How 58% of Polymarket Users Lose Money (And How DuelDuck's Model Is Different)
Bloomberg analyzed 2 million Polymarket wallets: 100,000+ lost over $1,000. The top 5% of accounts - mostly automated bots - took 75% of all volume. A London Business School/Yale study: only 3% of traders drive price discovery. 84% of all Polymarket participants have realized net losses. Here is what the data actually shows, why retail traders are structurally disadvantaged, and how DuelDuck's creator model changes the math entirely.
Key Takeaways
- Bloomberg analyzed 2 million Polymarket wallets active since January 2025 (published April 29, 2026): over 100,000 accounts lost at least $1,000 - nearly double the 50,000 that gained the same amount. Strip out the top winners and the rest of the user base recorded a combined net loss of $131 million. Almost half of all 2 million wallets made or lost less than $10 - they were experimenting, not trading seriously.
- The top 5% of accounts took 75% of all Polymarket trading volume. These high-volume accounts - identified as likely automated bots by Bloomberg's analysis - made $131 million on their trades. 823 of these accounts netted more than $100,000 each. The typical bot averaged 89 trades on each active trading day versus 2.2 for non-bots.
- A London Business School/Yale working paper (April 26, 2026) analyzed 1.72 million Polymarket accounts and $13.76 billion in trading volume: only 3% of traders account for most price discovery. Among the biggest winners by raw profit, only 12% actually beat a coin-flip benchmark. Roughly 60% of 'lucky winners' turned into losers when tested on a separate sample of events.
- Researcher Andrey Sergeenkov (April 8, 2026): 84.1% of Polymarket's 2.5 million traders are not profitable. Only 2% have made more than $1,000. Just 0.32% are profitable to the tune of $10,000+. A mere 840 addresses - 0.033% of all users - earned more than $100,000. This profitability rate has fallen from 40% two years ago as the user base expanded post-2024 US election.
- The median retail user of prediction markets loses 8% of their money - a worse outcome than the typical loss in legal sports betting, according to analysis cited in The Plain Bagel financial commentary. The bottom 95% of earners made 56% of their trades at extreme odds (below 10 cents or above 90 cents) - the worst possible entry points - compared to 28% for the top 0.1% of earners.
What Percentage of Polymarket Users Actually Make Money?
A Bloomberg News analysis of every Polymarket wallet active since January 2025 found that more than 100,000 accounts lost at least $1,000 - nearly double the number that made the same amount. A separate study by Andrey Sergeenkov found that 84.1% of Polymarket's 2.5 million traders are not profitable. A London Business School and Yale working paper found that only 3% of traders drive price discovery on Polymarket, while the rest lose money around them. The top 5% of accounts - largely automated bots - account for 75% of all trading volume. DuelDuck's creator model is structurally different: creators earn up to 5% net creator fee on every pool regardless of whether they win or lose the underlying prediction.
The Data: Four Studies, One Conclusion
Four independent analyses were published or circulated in April 2026, each using different methodologies and data sources, all arriving at the same conclusion: retail participants on Polymarket are structurally disadvantaged against a small group of informed, often automated, high-volume traders.

Why Retail Traders Lose: The Three Structural Disadvantages
Disadvantage 1: Bots Enter First at Better Prices
Bloomberg's analysis found the typical bot averaged 89 trades on each active trading day versus 2.2 for non-bots. Bots operate at millisecond speed, executing the moment new information (news releases, data publications, social media signals) enters public channels. By the time a human trader reads an article, processes the implications, and enters a position, bots have already moved the market price.
A retail trader who correctly identifies that WTI oil will hit $110 before month-end may be right - but if the bot bought the contract at $0.30 (30% probability) and the retail trader enters at $0.55 (after bots have moved the price), the retail trader's correct prediction produces a much smaller return than the bot's identical conviction. Being right is not enough. Timing and entry price determine profitability.
Disadvantage 2: Retail Traders Trade at Extreme Odds
The University of Toronto/HEC Montreal/ESSEC study found the bottom 95% of earners made 56% of their trades at prices below 10 cents or above 90 cents - the extreme ends of the probability spectrum. The top 0.1% of earners made only 28% of their trades at these extremes.
Trading at extreme odds creates a specific profitability trap: a 5-cent contract (5% probability) must be bought 19 times and win once just to break even. Retail traders who buy long-shot contracts consistently overpay for lottery-ticket-style positions. Professional traders and bots concentrate in the 20-80 cent range where market pricing is most efficient and edge can be extracted without requiring extreme outcomes.
Disadvantage 3: Information Asymmetry
The London Business School/Yale paper found only 3% of traders drive price discovery on Polymarket. These are participants with genuine information advantages: professional analysts who model events better than consensus, energy traders who understand Hormuz shipping data, music superfans who track chart algorithms, and - in some documented cases - participants with non-public information. These 3% move prices toward the correct outcome. Everyone else trades at prices already set by better-informed actors.
The Maduro insider trading case illustrated this in extreme form: three newly created Polymarket accounts bought contracts at 10% probability hours before Operation Absolute Resolve was announced. The accounts made over $630,000 collectively. The retail participants who sold them those contracts at 10% were pricing the event fairly based on public information - and lost to participants with classified knowledge. This is the information asymmetry problem in its most acute form.
The Wisdom of Crowds Myth: What the Data Actually Shows
Prediction markets are justified to regulators, media, and the public on the basis of the 'wisdom of crowds': the idea that collectively aggregating many participants' estimates produces more accurate forecasts than any individual expert. The academic literature from the Iowa Electronic Market supports this claim for well-structured markets. Polymarket's 2024 US election prediction (favoring Trump when polls showed a coin flip) is cited as the flagship example.
The London Business School/Yale paper challenges this narrative directly: prediction market accuracy on Polymarket comes from 3% of traders, not from the crowd. The '97%' are not contributing to price discovery - they are providing liquidity that the informed 3% trade against. The market produces accurate prices not because of crowd wisdom but because a small number of skilled (and sometimes insider-informed) participants move prices toward correct values.
Pablo Martineau, co-author of a related paper from University of Toronto, HEC Montreal, and ESSEC: 'You'd be surprised how many of them did not anticipate that you would see such concentrated gains — that so few make money.' His students who had been enthusiastically trading on prediction markets were 'taken aback' by the findings.
The Social Media vs. Reality Gap
Prediction markets are marketed on social media as a lucrative side hustle. A Polymarket referral program offers 30% of trading fees generated by referred participants - creating a wave of influencer-driven content showcasing large wins. The gap between social media presentation and data reality is significant:
Social media narrative | Data reality |
'I paid off my rent through Kalshi predictions' | 840 Polymarket addresses (0.033%) earned more than $100,000; 100,000+ lost more than $1,000 |
High-accuracy traders sharing win screenshots | Only 12% of biggest winners by raw profit beat a coin-flip benchmark; 60% of 'lucky winners' become losers on separate event samples |
'Anyone can make money with good research' | The median retail user loses 8% - worse than typical sports betting losses |
'Prediction markets are peer-to-peer' | 5% of accounts (largely bots) take 75% of volume; the 'peer' is typically an automated algorithm |
'Join the prediction market revolution' | Profitability rate has fallen from 40% to 15.9% as user base expanded post-2024 election |
Kalshi's user base is 24% under age 25, compared to just 7% for traditional sportsbooks like DraftKings. Young, first-time traders are the most represented demographic on a platform where 84% lose money. Research shows men aged 30 and under who wager on sports have a 10% rate of gambling problems. The prediction market demographic overlap with this risk group is significant.
The Three Paths to Profitable Prediction Market Participation
The data does not mean all prediction market participation is hopeless. It means the standard retail trading model - buy contracts, hope to win, repeat - is structurally disadvantaged. Three alternative models produce better outcomes:
Path 1: Develop Genuine Domain Expertise
Brandon Fean (music teacher) made $100,000 trading Ariana Grande charts. Caleb Davies made $389,000 on culture markets. Both had domain knowledge that general market participants lacked. Domain expertise converts to information edge that allows entry before the general market reprices. The London Business School paper confirms: skilled participants - those who beat the coin-flip benchmark - make money consistently. The problem is that most participants think they have domain expertise when they do not.
Path 2: Trade in Thin Markets Before Bots Dominate
Bot dominance is concentrated in high-volume markets (major election contracts, NBA finals, WTI oil). Niche markets - a specific Grammy category, a reality TV weekly elimination, a small-cap company KPI contract - have less bot activity because the volume does not justify algorithmic infrastructure. Participants with domain knowledge in niche categories can find edge that evaporates in high-volume markets.
Path 3: Create Duels Instead of Trading Them
DuelDuck's creator model offers a fundamentally different economic relationship with prediction markets: creators earn income regardless of whether their prediction is correct. A DuelDuck creator who designs a Grammy winner duel, distributes it to a music fan community, and earns a 5% net creator fee on a $1,000 pool has made $50 without taking any directional risk on the outcome. The creator income is not a trading profit - it is a platform fee for market design and distribution work.
DuelDuck's Creator Model: Income Without Directional Risk
The structural problem for retail Polymarket participants is that they must predict correctly and enter at good prices to make money. DuelDuck's creator model decouples income from prediction accuracy. Compare the two models:
Model | Income source | Requires correct prediction? | Exposed to bot competition? | Typical participant outcome |
Polymarket retail trading | Win on correct predictions | Yes - must be right AND enter before market moves | Yes - 5% of accounts take 75% volume | 84% not profitable; median loses 8% |
Kalshi retail trading | Win on correct predictions | Yes - must be right AND enter before market moves | Yes - similar bot dynamics | Similar structural disadvantages (Citizens analysis cited) |
DuelDuck community trading | Win on correct predictions | Yes - same information asymmetry applies | Lower - P2P community model, less bot infrastructure | Same informational dynamics; 50/50 entry advantage offsets some disadvantage |
DuelDuck creator role | 5% net creator fee on pool size | No - creator earns regardless of outcome | Not applicable - creator sets the question, not the position | Up to 5% net fee on every pool regardless of which side wins |
The Creator Fee Math
A DuelDuck creator who builds a consistent weekly publishing schedule earns predictable income without directional prediction risk:
5 weekly duels at $500 average pool: $2,500 pool volume per week, $125 net creator fee per week, $6,500 per year from weekly music/sports/culture duels alone
One major event duel (Grammy season, $2,000 pool): $100 net creator fee from a single event
Annual prediction market calendar: Grammys, Oscars, NBA Finals, World Cup, PGA majors, US elections, major economic releases - 52+ weeks of continuous creator income opportunities
The comparison to Polymarket retail trading: a Polymarket participant who deposits $2,500 and trades weekly has an 84% probability of being unprofitable. A DuelDuck creator who publishes 5 duels per week at $500 average pool earns $125/week with zero directional exposure to prediction outcomes.
What to Do If You Are Already Losing on Polymarket
If the data describes your experience on Polymarket or Kalshi, four concrete adjustments change the math:
Audit your trade timing, not your predictions. Track whether you enter positions before or after significant price moves. If you consistently enter after the market has already moved, you are experiencing the bot disadvantage. Shift toward niche markets where bot infrastructure is less competitive.
Stop trading long-shot contracts. The bottom 95%'s tendency to trade below 10 cents and above 90 cents is the single most damaging behavior pattern identified in the data. Contracts below 10 cents require 9 correct wins to offset 1 loss. Focus on markets priced 20-80 cents where the probability distribution is most accurate.
Build a creator income stream instead of or alongside trading. DuelDuck's creator model generates fee income regardless of prediction accuracy. For participants who enjoy the prediction market ecosystem but are not in the profitable 16%, creator income provides a sustainable alternative income stream that does not depend on beating bots at their own game.
Identify your actual domain expertise. The profitable 3% of traders have genuine informational advantages. Brandon Fean had Ariana Grande HTML code. Caleb Davies had streaming momentum models. Energy traders have EIA data workflows. Before trading, identify what specifically you know that the general Polymarket market does not price correctly. If the answer is 'I follow the news' or 'I have good intuition,' the data suggests caution.
Conclusion: The Industry's Uncomfortable Data
Bloomberg published the wallet analysis on April 29, 2026 - the same week Polymarket was reportedly raising $400M at a $15B valuation. The juxtaposition is striking: the platform is worth $15 billion partly because 84% of its participants consistently lose money to the 16% who consistently win. This is not a bug - it is how financial markets are structured. The question is whether prediction market participants understand which group they are in.
The data from Bloomberg, Sergeenkov, London Business School, and the University of Toronto consortium is not evidence that prediction markets do not work. They work extremely well for price discovery - because the 3% of skilled, often automated, participants move prices toward correct values. The crowd provides the capital. The informed minority provides the accuracy.
For participants who want to engage with prediction markets sustainably, three options exist: develop genuine domain expertise that puts you in the profitable 3%; trade in niche markets where bots have less infrastructure; or build creator income on DuelDuck that decouples your earnings from prediction accuracy entirely.
The question is not whether prediction markets are profitable. The question is which side of the information divide you are on - and whether your model depends on being right or on being useful.

Frequently Asked Questions
Multiple studies converge on different estimates. Bloomberg's April 2026 analysis of 2 million wallets found that those losing more than $1,000 nearly doubled those gaining the same amount. Researcher Andrey Sergeenkov found that 84.1% of Polymarket's 2.5 million traders are not profitable. A TU Berlin/German International University study found approximately 70% of Polymarket trading addresses have realized losses. The profitability rate has declined from approximately 40% two years ago as the platform grew after the 2024 US election. Only 840 Polymarket addresses (0.033% of all users) have earned more than $100,000.
Three structural factors drive retail losses on Polymarket. First, bots: the top 5% of accounts (largely automated) take 75% of trading volume, entering positions at better prices before human traders can react. The typical bot averages 89 trades per active day versus 2.2 for human traders. Second, extreme odds trading: the bottom 95% of earners make 56% of their trades at prices below 10 cents or above 90 cents, the worst possible entry points. Third, information asymmetry: a London Business School/Yale working paper found only 3% of traders drive actual price discovery; the remaining 97% trade at prices set by better-informed participants.
Yes, but the profitable group is small and specific. The London Business School/Yale paper identified a group of skilled traders who consistently beat a coin-flip benchmark and drive price discovery. Documented cases include Brandon Fean (music teacher) who made $100,000 trading Ariana Grande chart predictions, and Caleb Davies who made $389,000 on Kalshi culture markets. Both had specific domain expertise that general market participants lacked. Without a genuine information edge, the data suggests most participants will lose money in the medium term. An alternative is DuelDuck's creator model, which earns up to 5% net creator fee per pool regardless of prediction accuracy.
Bloomberg identified Polymarket bots as accounts averaging 89 trades per active day, spread across many markets. The top 1% of accounts, largely bots, captured over 80% of all profits. Bots enter positions at the moment new information becomes public - typically milliseconds before human traders can react. By the time a retail trader enters the same position, the price has already moved. The retail trader can be correct in their prediction but earn a fraction of what the bot earned for the same view. Bots also concentrate in high-volume markets (major elections, sports championships, WTI oil) where the trading volume justifies algorithmic infrastructure.
DuelDuck has several structural differences from Polymarket for retail participants. Every DuelDuck pool opens at 50/50 regardless of Polymarket or Kalshi consensus pricing, giving community participants better entry prices than consensus-priced markets. DuelDuck's P2P community model has lower bot penetration than Polymarket's general markets because individual community pools are smaller and less valuable as algorithmic targets. Most importantly, DuelDuck's creator model offers a different economic relationship: creators earn up to 5% net creator fee on every pool regardless of prediction outcome - a fee income stream that does not require correct predictions or competition with automated traders.
The DuelDuck creator model allows participants to design and distribute binary prediction duels for their community and earn up to 10% gross creator fee (50% platform share; creator nets up to 5%) on every pool. A creator who publishes a Grammy winner duel and attracts $1,000 in total pool size earns $50 net regardless of which artist wins. Creator income is a platform fee for market design and community distribution work, not a directional trading profit. This model does not require correct predictions, does not compete with algorithmic traders, and generates predictable income from a consistent publishing schedule. It is structurally different from retail trading on Polymarket where profitability depends on being in the profitable 16%.
According to researcher Andrey Sergeenkov's April 2026 analysis, the average trade size on Polymarket is $89. This small average trade size reflects the majority of participants who are experimenting with small amounts: Bloomberg found that almost half of 2 million active wallets made or lost less than $10 total. This experimental participant base provides liquidity that professional and bot traders exploit. The gap between the average $89 trade (retail) and the bot trades (which averaged 89 per active day) illustrates the scale difference between the two groups competing in the same market.
The median retail user of prediction markets loses 8% of their money, according to analysis cited in The Plain Bagel financial commentary. This is described as a worse outcome than the typical loss in legal sports betting. A report from Citizens analysts suggested users are losing proportionately more on Kalshi than they do on sports betting apps - though Kalshi rejected that analysis. The comparison matters because prediction markets are positioned as a financial product with information edge potential, while sports betting is regulated with problem gambling protections and age requirements. The actual loss rates for retail participants may be higher on prediction markets because the information asymmetry between bot/professional traders and retail is larger than in traditional sportsbooks.
