Nearly seven in ten retail accounts trading on Polymarket have lost money, according to new onchain analysis that estimates 69.2% of the cohort is unprofitable and has accumulated $338.9 million in aggregate losses. The figures offer a stark look at how trading outcomes are distributed across the prediction market, where users buy and sell contracts whose prices reflect the market-implied probability of future events.
Importantly, the data describe trading accounts or wallets identified within the analysis rather than necessarily unique individual people. A single trader can control multiple addresses, while methodology around realized versus unrealized profit and loss can also materially affect the results.
The 69.2% figure therefore should not be interpreted as proof that precisely 69.2% of every person who has ever used Polymarket has lost money. It nevertheless points to a pronounced imbalance between the large number of smaller losing accounts and a much narrower group capturing substantial profits.
Retail Losses Reach $338.9 Million
According to the analysis, losing retail accounts have generated $338.9 million in aggregate losses, illustrating how prediction-market activity can produce outcomes resembling other highly competitive trading markets.
A Polymarket contract generally settles at $1 if the specified outcome occurs and $0 if it does not. Before resolution, contracts can trade anywhere between those values as participants continuously update their expectations and positions.
That structure means correctly predicting an outcome is not necessarily sufficient to make money.
A trader purchasing a contract at 90 cents needs the underlying event to occur frequently enough to justify repeatedly risking 90 cents for a maximum $1 payout. Conversely, buying low-probability contracts can generate occasional large percentage returns while still producing losses if the market price systematically overstates the trader’s actual edge.
Active traders can also lose money through poor entry prices, changing probabilities and repeatedly exiting positions before resolution. The result is a market where informational advantage and price discipline matter alongside simply identifying the eventual winner.
Prediction Markets Are Becoming a Larger Trading Venue
The findings arrive as Polymarket evolves from a niche crypto application into a substantial event-trading marketplace.
The platform experienced explosive growth around the 2024 U.S. presidential election and subsequently expanded markets covering politics, economics, cryptocurrency, sports and other events. That growth has attracted professional traders, market makers and data-driven participants alongside casual users.
The distribution of profits and losses therefore matters when assessing prediction markets as consumer products. Markets can aggregate information efficiently while still producing sharply different financial outcomes for individual participants.
Large traders may benefit from superior models, faster information processing, automated execution or the ability to provide liquidity across many contracts. Retail participants may instead trade relatively small positions based on conviction about individual events.
There are also limitations to drawing behavioral conclusions solely from public blockchain data.
Wallet-level analysis cannot always determine whether addresses belong to the same participant, whether positions are hedged elsewhere or whether an account’s activity represents discretionary retail trading, professional market making or automated strategies.
Aggregate realized losses also do not necessarily equal money retained by Polymarket itself. Prediction contracts redistribute economic gains and losses among market participants, while the platform and intermediaries may separately earn fees.
The figures therefore provide evidence about trading outcomes rather than Polymarket’s revenue. Still, the headline result is substantial. If 69.2% of the accounts classified as retail in the dataset are losing money, the data suggest that the rapid expansion of prediction markets has not translated into broadly distributed trading profits.
Instead, Polymarket increasingly resembles other speculative markets in one im: participationportant respect is widespread, but sustained profitability appears considerably more concentrated.
