69% of All Traders on Polymarket Are Unprofitable

Data released by PredictParity shows that 69% of traders historically on Polymarket are unprofitable. The site, an analytics platform dedicated to tracking prediction markets, found that 53% of traders have lost between $1 and $100 trading on Polymarket.

Conversely, 31% of traders are profitable, with 23% earning between $0 and $100 historically.

This data is drawn from a pool of over 2.4 million traders across all time, revealing the everyday reality of what trading on a prediction market like Polymarket actually looks like.

Unprofiltable traders

More than 1.29 million traders, representing over half of the entire all-time user base, saw lifetime losses of $100 or less.

While the narrative around Polymarket and prediction markets often focuses on stories of high-stakes gambling, these micro-losses actually form the backbone of the platform’s community.

As the stakes climb, the numbers thin out. A small fraction of the user base faced significant financial hits: roughly 11,500 people lost more than $10,000, and an elite “underclass” of just 80 individuals recorded losses exceeding $1 million.

Profitable traders

On the other side of the ledger, the 31% of traders who finished in the green tell a similar story of modest returns for the masses. Nearly 561,500 people, or roughly 23% of all users, walked away with a profit of $100 or less. 

This suggests that for most, “winning” on Polymarket is enough to cover a nice dinner but not a career change. 

Fewer than 11,000 traders managed to cross the $10,000 profit mark. 

The true whales of the platform are a rare breed. Only 104 traders, a mere 0.0043% of the total population, achieved the milestone of $1 million or more in lifetime winnings. Interestingly, while there are slightly more million-dollar winners than losers, the low-stakes $1 to $100 range remains the most common experience, where losers outnumber winners by more than two to one.

The data

Predict Parity is a specialized on-chain analytics platform that focuses specifically on prediction markets. Because Polymarket is built on the Polygon blockchain, every single trade, win, and loss is recorded publicly on a decentralized ledger.

Parity scrapes these millions of blockchain transactions and transforms the raw numbers into readable analytics, revealing big-picture trends like the profit and loss distribution chart.

Further data available on Parity includes tracking for specific wallets, live market spreads and liquidity, and historical forecasting accuracy to see how reliably these markets predict real-world events over time.

Prediction markets are accurate at scale

Prediction markets grew rapidly in mainstream awareness because of how accurate they proved to be.

Polymarket and Kalshi predicted the 2024 U.S. election of Donald Trump more accurately than official pollsters did. And since then, they have proven again and again to get it right.

This is because humans as a collective have an innate ability to average out to the most accurate answer.

A great example of this is the classic “wisdom of the crowd” experiment involving a jar full of jelly beans. 

When you ask individuals to guess how many beans are in the jar, their personal estimates are usually wildly incorrect. But when you take hundreds of those independent guesses and average them together, the final number is almost always strikingly close to the exact count.

So the strength of the predictions on Polymarket is not in individual traders but as a collective. The more traders there are, the more accurate the predictions tend to be.

These platforms are so reliable that major financial data services like Bloomberg have integrated Polymarket odds directly into the Bloomberg Terminal. Meanwhile, traditional outlets like The Wall Street Journal and CNBC regularly cite their data, using them as crowdsourced pollsters in the modern media landscape.

Where the money goes: Bot trading

Many of the top accounts on Polymarket are not human; they are high frequency trading (HFT) bots acting as market makers. These algorithms aim for small, marginal gains by taking both sides of a market, placing bets on “Yes” and “No” simultaneously to capture the spread. By collecting just fractions of a cent per trade and repeating the process thousands of times, the most sophisticated of these algorithms generate massive profits over time.

Data released by Predict Parity highlights exactly how pervasive this is. They identified 5,785 bot accounts responsible for a staggering 39.9% of Polymarket’s total trading volume. Collectively, these bots have generated over $104 million in cumulative profit.

Interestingly, running a bot does not guarantee success. The data shows that roughly 62% of these automated accounts actually operate at a loss. However, a small handful of elite algorithms at the very top pull in enough millions to overwhelmingly skew the total bot profit into the green.

Ultimately, while everyday traders are experiencing widespread micro losses, this data reveals that a massive portion of that lost money is going directly into the pockets of a few highly optimized algorithms playing the spread.
