Only 1 in 5 Polymarket traders ever turns a profit. We checked all 1.5 million wallets.

Prediction markets are sold as the place where being right pays. The pitch is seductive: do your homework, bet your conviction, beat the crowd. So we asked the only question that matters — across everyone who has actually traded on Polymarket, how many walked away with more than they put in?

We have the data to answer it directly. Not a sample, not a survey — every trade settled on-chain on Polygon, aggregated per wallet. The answer is brutal.

The breakdown

Here is the split, straight from aggregated wallet P&L. "Not profitable" means a wallet ended at break-even or a loss — it did not make money.

Two honest readings live in that table:

• Across everyone, only ~1 in 5 is profitable. A huge slice — 37.8% — sits at almost exactly zero, the signature of accounts that placed a bet or two and stopped.
• Among people who actually played — 20+ resolved markets — the break-even crowd disappears and 62% are flat-out underwater. Filtering to serious participants doesn't rescue the average. It makes it worse.

Either way you cut it, the modal Polymarket outcome is not "small profit." It's "no profit."

This isn't just our data

We're not the first to land here, and that's the point — independent datasets converge on the same story.

• A widely-cited analysis by on-chain researcher Andrey Sergeenkov covering 2.5 million wallets found 84% of traders lost money, with only ~2% accumulating more than $1,000 in profit.
• A separate study of 124 million trades found 70% were unprofitable.
• The Wall Street Journal's investigation into Polymarket and Kalshi concluded that almost everyone loses except a small group of professional traders.

Our 20.6%-profitable figure is the same finding from a third, independent angle. When four datasets built by four different people all say "most people lose," that's not a methodology artifact. That's the base rate.

Where the money actually goes

The flip side of "most people lose" is "a few people win big." The winnings on Polymarket are extraordinarily concentrated:

• The top 1% of accounts capture 76.5% of all gains.
• The top 0.1% — fewer than 2,000 traders — take home 67% of all profits.
• Only 840 accounts (0.033%) have cleared more than $100,000.

This is a power law, not a bell curve. The median trader isn't competing against other amateurs for a fair slice — they're feeding a tiny cohort of sharp, persistent, often-coordinated wallets. Identifying those wallets is the entire reason CrowdIntel exists.

Methodology

Every wallet's realized P&L is aggregated from its on-chain Polymarket trades on Polygon. A wallet counts as "profitable" if its net realized P&L is greater than zero, "not profitable" otherwise. The all-wallet view includes every wallet with trade history; the active-trader view restricts to wallets with at least 20 resolved markets. P&L source of truth is each wallet's reconciled Polymarket figure, falling back to our computed total where Polymarket's isn't available.

Limitations

• Realized, not paper. Open positions aren't counted as wins or losses until they resolve. A wallet sitting on a large unrealized gain reads as break-even here.
• Wallets aren't people. One person can run many wallets; one wallet can be a shared or custodial address. "1.5 million wallets" is not "1.5 million humans."
• Break-even ≠ loss. We deliberately separate the two. The honest claim is "only 20.6% made money," not "79% lost money" — about half of that 79% ended near zero.

See it live

We built a live, always-current version of this chart that recomputes straight from on-chain data: crowdintel.xyz/loss.

If you'd rather study the 20% who do win, the profit leaderboard ranks them by real on-chain P&L, and the 3D galaxy shows the whole market at once — every wallet a star, green for profit, red for underwater, same-funder clusters pulled into bright knots. That's where the other side of this chart lives.
