Large trades·$10,000 and up·24-hour delay·Every Polymarket market
Polymarket whale tracker for sports and esports
Large Polymarket trades, $10,000 or more, with their side, size, odds, and the grade each wallet has earned on its settled record. Free reads it 24 hours behind, no account needed. Pro has no delay.
A fill enters the feed when all 4 of these hold. The wallet took the fill, trading against a resting order; the order it matched is not a second row. Its notional, shares times price, is $10,000 or more. Its price is under 97 cents. Its shares are at least 0.1% of the shares its market has traded.
Earnings markets count from $1,000 and up to 99 cents, because their books are thinner. The 0.1% rule withholds a fill only in a market that has traded at least 1,000 times its shares.
The same rules apply to every Polymarket market: the NFL, the NBA, MLB, soccer, tennis, CS2, and the rest. Each row is one fill, deduplicated, by a wallet whose record is public.

How to read a large-trade row
Side is BUY or SELL of the outcome named after the market. A sell reduces or closes the wallet's position in that outcome.
Size is the notional in USDC, shares times price, the number the floor is applied to. Odds is the fill price in cents: 63c means the market priced the outcome at 63% when the trade landed.
The grade beside the trader runs S to F, from the wallet's realized profit on settled markets. Unranked means the wallet has no grade yet: it has fewer than 5 markets, or its history is still loading.
03
Why the wallet grade matters
Size measures conviction or a hedge, not skill. A large buy from a wallet that has lost money across hundreds of settled markets is a different fact from the same buy by a wallet graded S, and the row shows which one it is.
In the October 7, 2026 run of the grade study, which graded 79,580 Polymarket buys of $10,000 or more as of each trade, S wallets beat the price they paid by 1.73 points and A wallets by 1.12. B wallets, whose grade certifies a profitable record, lost to it by 0.91. The method, the confidence intervals, and the SQL are in the study.
The delayed feed is open to everyone, no account needed. This page shows trades at least 24 hours old. The live feed shows the same delay across the last 7 days; a signed-out visit stops at 50 trades on page one, and an account pages through the rest of the window and adds Market Strength on a covered market.
Pro removes the delay, opens filters by sport, size, and side, keeps the full searchable history, and sends a daily email of the largest trades of the last 24 hours.
On 0xinsider, a large trade is a fill the wallet took, of $10,000 or more in notional, at a price under 97 cents, and at least 0.1% of the shares its market has traded. Earnings markets count from $1,000. The wallet behind it is graded on its settled record, so the feed separates a large wallet from a profitable one.
How do I track large trades on Polymarket?+
Open this page or the live feed. Each row shows the side, the market, the size, the fill price and the wallet's grade, and links to the wallet's profile and the market's page. Pro adds filters by sport, size, and side, and a daily email of the largest trades.
Is the large-trade feed real-time?+
The feed on this page is at least 24 hours old. The live feed shows the last 7 days on the same delay, signed in or not. Pro sees trades as they fill.
Does a big trade mean the trader is right?+
No. Size measures conviction or a hedge, not skill. The grade says more, at the top of the scale: in the October 7, 2026 run of the grade study, which graded 79,580 Polymarket buys of $10,000 or more as of each trade, S wallets beat the price they paid by 1.73 points and A wallets by 1.12. B wallets, whose grade certifies a profitable record, lost to it by 0.91.
Which markets does the feed cover?+
Every Polymarket market, under the same rules: the NFL, the NBA, MLB, the NHL, soccer, tennis, UFC, CS2, and other esports, plus politics, crypto, and the rest. The sports boards show which side the profitable wallets hold, game by game.
What does the wallet grade mean?+
A trader grade runs S to F. Banked realized profit sets about 95% of the grade. A skill tie-breaker settles the rest: forecasting edge, track record, win rate, risk-adjusted drawdown, and consistency. Any grade above C requires verified net-positive realized profit. A grade is a record of settled trades, not a prediction of the next one. Unranked means the wallet has no grade yet, which is not a low grade. A grade needs at least 5 markets and a fully loaded history: verified trading volume and daily P&L.
Can I copy large trades?+
0xinsider does not place trades. Each row links to the wallet's profile, where its settled record and other large trades are, and to the market on Polymarket, where a trade is placed.
Is 0xinsider affiliated with Polymarket?+
No. 0xinsider is an independent analytics site that reads Polymarket's public trade data. It does not place trades or hold funds. Links to Polymarket carry a referral tag.
