Abstract

Several financial assets, such as shares of GameStop or Dogecoin cryptocurrency,

became the focus of substantial speculation in early-2021 that resulted in high price volatility and

trading volume. This “meme asset wagering” appears to be closely related to the emergence of

zero-fee retail brokerages, high-leverage cryptocurrency exchanges, and social media investment

communities that facilitate and encourage risky behavior. As an emerging form of financial risk-

taking, little is known about participants in these markets. In this study, an internet-based sample

(n=643) was recruited to assess the relation between meme asset ownership, perceived risks in

gambling and investing, investment knowledge, and measures associated with gambling

problems. Results suggest that meme asset wagerers perceive less risk from financial uncertainty,

have higher levels of overconfidence in their investment ability, and have higher risk of

gambling problems. The findings suggest that these products may be treated like gambling by

some individuals.

Meme asset wagering: Perceptions of risk, overconfidence, and gambling problems

“I am become meme, Destroyer of shorts” – Elon Musk (2021)

Meme asset wagering is an emerging phenomenon in capital markets. It occurs when

individuals speculate on the price of a security or digital asset, despite the asset price becoming

materially disconnected from any reasonable measure of value (Chaumont, Gordon, & Sultanum,

2021; Umar et al., 2021). Wagering on the price of meme assets is not well understood as a

social phenomenon but tends to involve a large group of unrelated individuals that use social

media to coordinate behavior around the purchase of an asset, to increase its price (Hasso et al.,

2022; Lyócsa et al., 2022).

Coordination among meme asset holders occurs without a mechanism to ensure that

others hold their position, which leads to a risk of large price decreases. What therefore emerges

is a zero-sum game where participants must assess whether popularity and growth is likely to

continue, or whether participants are likely to sell in the future. Unlike most games, meme asset

wagering does not have a traditional randomization mechanism such as dice, cards, or pseudo-

random number generators. Meme wagering also excludes speculation on asset productivity,

which differentiates it from more traditional financial securities where excessive risk-taking

centers on rare events that impact the underlying value of assets (Kumar, 2009).1 Instead, price

movements largely occur as a function of buyer sentiment (Cary, 2021; Divesh et al., 2022;

The term ‘meme asset wagering' does not characterize all meme asset holders as gamblers.
Market participants may have sophisticated strategies with a positive expected value. For instance, any
individual that held a US index fund likely had some exposure to meme assets. Semantically, the meme
wagering term distinguishes this risk-taking behavior from other forms of financial speculation, which
typically describe sources of equity returns through value generation that may be volatile or uncertain. For
example, speculating that a quarterly earnings report will exceed market expectations or that a
pharmaceutical company will receive a favorable clinical trial result.

Lansiaux et al., 2022; Umar et al., 2021). Overall, the distinguishing feature of meme wagering

is a collective willingness to coordinate purchase of a specific asset over a relatively short period

of time.

In traditional markets, the best recent example of a meme asset is GameStop stock during

early-2021. Largely coordinated through the WallStreetBets subreddit, an over 16-fold

appreciation in price occurred in January 2021, followed by similar sized collapse by February

2021 (Chaumont, Gordon, & Sultanum, 2021). While not all buyers were motivated by the

gambling-like properties of these assets (Anderson et al., 2021), many subreddit participants

describe their behavior as gambling (e.g. Ned_Flanderz, 2021) and many GameStop buyers had a

history of purchasing stocks with lottery-like features (Hasso et al., 2022). In digital assets, the

most widely cited example is Dogecoin, whose promotion by Elon Musk and others led to the

limited-utility cryptocurrency reaching a market capitalization of over $15 billion in 2021

(Shahzad et al., 2022).

In both GameStop and Dogecoin, trading volume increased, price became disconnected

from prior levels, and volatility grew exponentially before settling at new levels (see Figure 1).

Interest and activity followed a path that appears similar to either a novelty effect or the

gambling exposure/adaptation curve, with an early spike in activity that was followed by a

longer tail of reduced intensity in involvement (LaPlante & Shaffer, 2007).

Figure 1 – GameStop and Dogecoin price and volume activity before and after their peak periods of
interest.

Over-optimistic speculation on financial assets has been discussed as early as John

Maynard Keynes’ (1936) description of “animal spirits” in markets, but new technologies appear

to have magnified these effects in more recent years. Social media-based investment

communities have encouraged risk-taking (Cary, 2021; Divesh et al., 2022; Umar et al., 2021)

while high-leverage cryptocurrency exchanges and zero-fee retail brokerages have facilitated

activity (Barber et al., 2020). Although capital markets serve an important role in personal

finance and wealth building, these technology platforms increasingly appear to be used as a

venue for coordinated social gambling and there appears to be a strong memetic effect of social

platforms for growing interest in specific assets (Ante, 2021; Chaumont, Gordon, Sultanum, et

al., 2021). As a result, public attention has grown. Cryptocurrency analytics site,

CoinMarketCap, actively tracks over 300 assets in their ‘meme’ category of tokens

(CoinMarketCap, 2022).

Understanding the nature of this potentially speculative activity is important to decisions

around the regulatory framework of retail financial products and the clinical practice in treating

gambling problems. Recent research demonstrates that high volume cryptocurrency or retail

investment activity is correlated with measures of excessive gambling (Delfabbro et al., 2021;

Oksanen et al., 2022) but little is known about meme assets specifically, which appear to be

among the most volatile. It is unclear whether participants in these markets view their behavior

as risky or whether they are at the same risk of problems as traditional gamblers. It is similarly

unclear if meme asset holders are knowledgeable of financial risks and are allocating small

amounts of capital for entertainment purposes or whether there is excessive risk-taking. In this

study, an internet-based community sample was recruited to assess the relation between meme

asset ownership, perceived risks in gambling and investing, investment knowledge, and measures

associated with gambling problems.

Hypotheses

Several authors have identified behavior that is consistent with gambling on financial

assets, where there appears to be a subset of investors who seek higher volatility in returns in

order to receive a potentially larger payoff. Kumar (2009) examined data from a discount

brokerage in the early 1990s and found that retail investors preferred equities with lottery-like

distributions. Similarly, Dorn et al. (2015) found evidence that individuals were substituting

lottery play and retail brokerage trading based on lottery jackpot sizes. Gong et al. (2021) found

that investors’ preferences for lottery-type outcomes tend to be strongest during downturns in the

markets. Similarly, Pelster et al., (2019) found that cryptocurrency traders are more risk-seeking

in stocks cryptocurrency volatility was low. Other work has focused on behavior related to

speculative bubbles where market participants collectively overestimate asset values (Scherbina

& Schlusche, 2014). These findings suggest that individuals who are willing to own more

volatile financial assets may subjectively view them as less personally risky than non-owners.

H1: Meme asset ownership is related to reduced relative perceptions of financial risk-taking

In both finance and gambling, overconfidence appears to be related to increased risk-

taking (Allen & Evans, 2005; Glaser & Weber, 2010; Goodie, 2005; Grinblatt & Keloharju,

2009; Philander & Gainsbury, 2021). Overconfidence tends to emerge in two ways, better-than

average biases and miscalibration effects (Glaser & Weber, 2010). Better-than average biases

occur when individuals believe that they are more knowledgeable or skilled than a typical

participant and therefore believe they can outperform, such as in a financial market or poker

game. This is connected to illusion of control biases (Langer, 1975), where individuals believe

their skill will enable them to earn excessive returns. Miscalibration effects occur when

individuals systematically fail to accurate account for the probability and magnitude of tail-risks

(Glaser & Weber, 2010). For example, failing to accurately account for the low-probability of a

lottery jackpot or the risk of ruin from financial asset volatility (Taleb, 2007). Owners of meme

assets may therefore be more likely to have misplaced confidence in their ability to understand

financial markets.

H2: Meme asset ownership is related to increased relative overconfidence in understanding of

financial markets

In gambling studies, some authors have found that active trading of securities or

cryptocurrencies is a risk-factor for developing an addictive disorder (Delfabbro et al., 2021;

Mills & Nower, 2019; Oksanen et al., 2022). Although these results are largely correlational,

there are features of meme wagering that may match or accentuate these risks further. For

instance, there is evidence that demand in cryptocurrencies follows a fear-of-missing-out pattern,

where positive price changes impact volatility more than negative changes (Baur & Dimpfl,

2018; Bouri et al., 2019; Shahzad et al., 2022; Song, 2022). As this behavior grows and evolves,

the sudden changes in asset prices may heighten financial losses. Further loss chasing may be

accentuated by norms around “buying the dip” in prices (Ardia et al., 2022). Accordingly, it is

important to regulatory and health outcomes to understand how consumption of meme assets is

related to both personal finance behavior and gambling-like harms.

H3: Meme asset ownership is related to increased problem gambling risk levels

Method
Recruitment
Ethics clearance was granted by [REDACTED] Human Research Ethics Committee, who

found the study exempt from review. Only US participants were recruited to ensure that there

were no legal restrictions to the capital markets where the assets were traded. Respondents were

recruited online since the platforms where the assets are traded and discussed are predominantly

online. To evaluate the survey instrument, an initial group of 228 participants were recruited in

April 2021 using Amazon Mechanical Turk (MTurk), an online web-based platform for human

tasks. Data was collected using Qualtrics. Participants were restricted to those with an MTurk

approval rating of at least 95 percent, consistent with practices adopted in previous research

(Goodman et al., 2013). The first group of participants only included respondents that received

the MTurk Masters designation for demonstrated excellence across a wide range of tasks. No

errors were discovered in the survey instrument and a second group of 415 US participants were

recruited in May 2021. To improve recruitment of relevant subjects, that group included

respondents that were prequalified by MTurk as owning common share stocks. To improve

response quality, responses were collected anonymously, respondents were asked to complete a

captcha before beginning the survey, and an attention screener question was asked mid-survey

(Berinsky et al., 2014). Study data is available upon request for approved research projects.

A total of 33 responses were removed due to failure to complete the survey and 55 were

removed due to failure of the attention screener. Study analysis used the remaining 555

responses. A majority of the respondents were male (58%); the median income band was

$60,000 to $69,999; age frequencies by age band were: 5 (1%, 18–20), 17 (3%, 21–24), 139

(25%, 25–34), 201 (36%, 35–44), 89 (16%, 45–54), 81 (15%, 55–64), 20 (4%, 65–74), and 3

(1%, 75–84); all respondents had a high school diploma or equivalent, and 71.0% had a

bachelor’s degree or higher. Just over half the sample (52%, n=287) reported owning a meme

asset in 2021.

Measures

Meme Asset Ownership

When meme wagering first emerged as a widespread phenomenon in early-2021, the

most high-profile examples were the “BANG” stocks: BlackBerry, AMC Entertainment, Nokia,

and GameStop (Lyócsa et al., 2022), and the Dogecoin cryptocurrency (Nani, 2022). To

operationalize meme asset ownership, respondents were therefore asked, “In 2021, which of the

following assets have you owned? (select all that apply)” and were given the option to select

from the “BANG” stocks and/or Dogecoin. Meme asset ownership is computed as the sum of

unique assets owned within that group. The totals categories are zero (n=268, 48%), one (n=145,

26%), two (n=77, 14%), three (n=44, 8%), four (n=10, 2%), five (n=11, 2%).

Perceptions of Financial Risk Taking

The Domain-Specific-Risk-Taking (Dospert) risk perception scale (Blais & Weber, 2006)

was used to assess perceptions of risk. The Dospert financial subscale includes both a gambling

and an investing component and assesses subjective views of perceived financial risk (see

Appendix A). Markiewicz & Weber (2013) found that a related Dospert gambling propensity

subscale assessing likelihood of engaging in activities predicts volume of trades by investors.

Respondents were instructed to indicate “how risky you perceive each situation” on a seven-

point Likert scale from Not at all Risky (1) to Extremely Risky (7). There are six questions and

scores can range from 6 to 42. The mean score was 26.24 (SD=6.33).

Overconfidence in understanding of financial markets

Overconfidence in understanding of financial markets (Overconfidence) was computed as

the difference in standardized subjective understanding and standardized measured

understanding (Philander & Gainsbury, 2021). Subjective understanding was assessed using a

question from Cox et al. (2020) based on findings from Glaser & Weber (2007), “Compared to

an average investor, how would you rate your investment abilities?” The five-point scale ranges

from much worse to much better and scores were then standardized. Measured understanding

was assessed using the “Big Three” financial literacy questions (Cox et al., 2020; Lusardi &

Mitchell, 2007), covering the nature of compound interest, inflation, and portfolio diversification

risk (see Appendix A). Scores ranged from zero to four and were then standardized.
𝑥 −𝑥̅

𝑦−𝑦̅

Overconfidence = 𝑆𝑖 𝑥 − 𝑆 𝑦

Where 𝑥𝑖 is the reported subjective understanding of respondent i, 𝑥̅ and 𝑆 𝑥 are the respective

sample mean and standard deviation of subjective understanding, 𝑦𝑖 is measured understanding

of respondent i, and 𝑦̅ and 𝑆 𝑦 are the respective sample mean and standard deviation of

measured understanding. The mean score was 0.05 (SD=1.37).

Problem gambling risk

A modified version of the nine question DSM-5 diagnostic criteria risk (see Appendix A)

was used to measure gambling problems, which followed prior studies by replacing the word

‘gambling’ with ‘trading financial products’ (DSM-5, Cox et al., 2020; Youn et al., 2016). The

response scale for each question is: (0) Never, (1) Sometimes, (2) Often, and (3) All the time.

Items are summed and scores can range from 0 to 27. There was good dispersion in measured

problems (M=2.25, SD=3.63).

Analytic strategies

Using the rstatix package (Kassambara, 2021), independent Welch t-tests were used to

test for pairwise differences between the zero meme asset ownership category and the non-zero

categories. Pairwise tests are used as the primary interest is to understand differences relative to

zero asset ownership, as opposed to differences between varying positive levels. Due to the small

group size of owners reporting four or five assets, the final categories were: zero, one, two, and

three or more, with the last category including all individuals who report owning three, four, or

five meme assets. The pairwise tests were used for Dospert scores, Overconfidence, and DSM-5

scores and were visualized as boxplots with difference lines. Similar tests with bootstrapped

standard errors and non-parametric tests are provided in an online appendix. To assess the

measures’ joint predictive ability, a regression model was estimated using all of the variables of

interest simultaneously, along with demographic control variables. Since the dependent variable

is cardinal, an ordinary least squares model is estimated but a similar ordinal probit model is

included in an online appendix. The ungrouped meme scores were used in the linear regression

analysis since there are not the same small group measurement issues when the variable is used

as a dependent variable in a linear regression.

Results
Perceptions of Financial Risk Taking

Findings supported H1. The respondents who owned no meme assets (M = 27.5, SD =

6.6) showed higher perceptions of risk in investment and gambling activity than respondents

with one meme asset (M = 25.5, SD = 5.6), t(338) = 3.27, p = .001, d = .33 ; two meme assets

(M = 24.9, SD = 6.3), t(127) = 3.12, p = .002, d = .40; or three or more meme assets (M = 24.4,

SD = 5.9), t(107) = 3.69, p < .001, d = .49. Boxplots of score distributions are provided in Figure

Regression analysis

Findings from the regression analysis demonstrate that the variables of interest have joint

predictive ability, supporting H1-H3. All of the variables are statistically significant and have

coefficients with the correct sign. The variance inflation factors (VIF) of the variables did not

exceed 1.43, suggesting low multicollinearity in the model. Age group was also statistically

significant and negative, suggesting that younger respondents were more likely to hold meme

assets.

Robustness Tests

To assess whether the results were driven by broad cryptocurrency ownership as opposed

to meme assets specifically, a series of regression models were estimated as robustness tests. In

Appendix B – Table I, a set of models use meme asset ownership count as an outcome variable,

fitting models with and without ‘Past 12-month cryptocurrency ownership’ as a control variable,

along with demographic controls. The results show robust effects from the variables of interest in

the study, regardless of cryptocurrency ownership status. In Appendix B – Table II, the variables

of interest are used as dependent variables and meme asset ownership count is used as an

independent variable. Again, a robust relationship is observed between meme asset ownership

and the variables of interest.

Discussion

Prompted by growth in low-fee retail brokerages, cryptocurrency networks, and social

media platforms, meme assets appear to be an emergent way in which individuals are wagering

on the internet. This study tested whether interest in meme asset ownership was related perceived

risks in gambling and investing, overconfidence in investing abilities, and/or increase risk of

gambling problems. Support was found for all three measures, suggesting that meme asset

holders perceive less risk from financial uncertainty, have higher levels of overconfidence in

their investment ability, and have higher risk of problems. The findings were found in bivariate

tests and were robust to a multivariate model specification. In addition, younger individuals were

found to be more likely to own meme assets. These results closely resemble findings from

gambling literature and suggest that these products may be treated like gambling by some

individuals.

The findings from this study underline an ongoing need to consider prevention programs

that target non-traditional forms of gambling, including some financial assets. Based on coverage

in media and public discourse (Davies, 2022; Fleming, 2021; Lee, 2020; Zweig, 2020), there

appears to be a trend towards potentially harmful risk-taking by consumers in financial services.

Security regulators have begun to focus attention on excessive risk-taking. For example, the

European Securities and Markets Authorities identified gamification and other product design

trends as “potentially impacting retail investors’ risk awareness” (ECON Exchange of Views in

Relation to GameStop Share Trading and Related Phenomena, 2021) and the U.S. Securities and

Exchange Commission stated before Congress that gamification could lead to a “substantial

effect on a saver’s financial position” (Testimony Before the House Committee on Financial

Services, 2021).

As financial services appear to be increasingly delivered using gamified products and

user experience designs (Fleming, 2021), wider trends seen in gaming-gambling convergence

(Kolandai-Matchett & Abbott, 2021) may further extend into retail risk-taking. Given the sharp

changes that occur in meme assets’ prices, financial ruin can happen quickly for individuals that

fail to understand the nature of the risks they may be taking. As over half of the sample in this

study owned at least one meme asset in 2021, the group at-risk of financial harms from meme

wagering may be a large share of retail investors. Promotion of meme assets by high-profile

public figures or online brokerages may further accelerate risk-taking and may not come under

the purview of institutions with experience in responsible gambling rulemaking. As meme asset

popularity grows, financial regulators and retail-product operators should consider adopting

standards of practice that promote financial literacy and understanding of gambling problems.

Better controls at all related institutions may serve to promote responsible investment activity

that is consistent with the purpose of capital markets.

Limitations and Future Research

This study used a non-random community sample and therefore has limited

generalizability to the general population. Inclusion of related questions in prevalence studies

would improve our understanding of the scale of involvement. This study predominantly focused

on breadth of involvement across major meme assets in early-2021. Part of the cultural

phenomenon during that period also appeared to be an encouragement on forums to allocate

capital into concentrated portfolios of meme assets, which would further increase risk of

substantial losses.

This study explored whether holders of specific meme assets have traits or behaviors that

share similarities with conventional gamblers, but the analytical methods do not imply a causal

relationship. It remains unclear whether meme asset ownership perpetuates the noted

relationships, whether there is a self-selection effect towards asset ownership, and/or whether

there are other confounding variables. Future behavioral studies using brokerage account and

cryptocurrency exchange data would help improve our understanding about the extent of meme

asset ownership as a share of total portfolios and the potential antecedents to ownership. Since

purchase of many cryptocurrencies is restricted by jurisdictions or exchanges, instrumental

variable approaches using availability constraints as instruments may be useful as an empirical

strategy to infer causality.

The robustness tests in this study address the potential confounding role of general

cryptocurrency ownership but those findings do not preclude the possibility of more complex

relationship. However, given that cryptocurrency ownership has become a relatively normative

activity in the United States – 23% adults are estimated to have owned cryptocurrency when this

study’s data was collected (PYMNTS.com & BitPay, 2022) – it seems likely that the results are

not being driven by a small cluster of statistically entangled group of cryptocurrency holders.

Future studies should more closely assess this relationship. The negative coefficient estimated

between general cryptocurrency ownership and the variables of interest may reflect a

differentiation between owners that are actively engaged in riskier meme asset wagering and

more passive cryptocurrency owners that view the asset class as one part of a broader investment

portfolio.

Future psychological studies should examine other dimensions in which meme asset

holders are similar to traditional gamblers, including further exploration of cognitive distortions,

habit formation, harms, and attitudes towards risk. This study used an adapted version of DSM-5

criteria for gambling problems. As use of financial products for gambling grows, more research

is needed to validate this and other gambling-related scales to understand where they may be

useful in understanding risk taking with meme assets and other financial services.

Appendix A – Study Instruments

The Domain-Specific-Risk-Taking (Dospert) risk perception scale (Blais & Weber, 2006)
Instructions: People often see some risk in situations that contain uncertainty about what the
outcome or consequences will be and for which there is the possibility of negative consequences.
However, riskiness is a very personal and intuitive notion, and we are interested in your gut level
assessment of how risky each situation or behavior is...

1) Suppose that you have $100 in a savings account, the interest is 20% per year, and you
never withdraw the money or interest. How much do you have in the account after 5
years?
•
More than $200
•
Exactly $200
•
Less than $200
•
Don't know

Please indicate how risky you perceive
1) "Betting a day's income on the outcome of a sporting event"
2) "Investing 5% of your annual income in a very speculative stock"
3) "Betting a day's income at the horse races"
4) "Investing 10% of your annual income in a new business venture"
5) "Betting a day's income at a high-stake poker game"
6) "Investing 10% of your annual income in a moderate growth mutual fund"
The “Big Three” financial literacy questions (Cox et al., 2020; Lusardi & Mitchell, 2007)

2) Suppose the interest on your savings account is 1% per year and the inflation is 2% per
year. After 1 year, can you buy more, exactly the same, or less than today with the money
on the account?
•
More than today
•
Exactly the same as today
•
Less than today
•
Don't know
3) Is the following statement true or false? “A company stock usually provides a less risky
return than an equity mutual fund.”
•
True
•
False
•
Don't know
Modified DSM-5 diagnostic criteria risk (DSM-5, Cox et al., 2020; Youn et al., 2016)
Instructions: The following questions are about your of trading of financial products, such as
individual company stocks, ETFs, derivatives, leveraged products, and cryptocurrencies. While
answering these questions please consider your actual trading activities during the last 12
months...

1) You trade financial products with larger amounts of money to maintain the excitement.
2) You have to borrow money from family members or friends to cover the losses from
trading in financial products.
3) You always think of ways to get money to trade financial products.
4) You lie to your family or friends about your trading in financial products.
5) You tried to reduce your trading of financial products, or to quit altogether, but could not.
6) You trade financial products to escape problems in your life.
7) You trade more in order to win back your previous losses.
8) You have problems in your work, with family members or with your partner as a
consequence of your trading in financial products.
9) You become irritated when trying to reduce or quit trading financial products.
