Polymarket Whale Tracker: Largest Trades, Live

Every Polymarket trade of $25,000 or more, newest first. Large trades often lead price moves, especially in thin political and geopolitical markets. This feed shows who bought or sold what, at what price and for how much, refreshed every 15 minutes from Polymarket's public trade data.

How to read the feed

• Trade says whether the trader bought or sold, and which outcome. "Bought No" at 70¢ means the trader paid 70¢ per contract that pays $1 if the event does not happen.
• Price is the price per contract, which is also the market's implied probability at that moment.
• Size is the cash that changed hands: number of contracts times price.
• Trader links to the public Polymarket profile, where you can see the trader's other positions and record. Compare with the Polymarket leaderboard to see whether a whale is also a consistent winner.

Only the side that took liquidity (the taker) is listed, so one trade appears once instead of twice.

Why whale trades matter

Polymarket settles on a public blockchain, so every trade is visible. In a market with $2 million of daily volume, one $100,000 order moves the price several points. That makes large trades useful for three questions:

1. Why did this market just move? If a whale bought heavily ten minutes before the jump, the move came from one trader's view, not from new public information.
2. Is the price reliable? A probability set by one large account is weaker evidence than the same probability set by thousands of small trades.
3. Is someone hedging? Large sells in a market that is not moving often mean a trader is reducing risk elsewhere.

Why you should not simply follow whales

A whale trade is information, not a tip.

• Whales lose too. Large accounts appear on both sides of most big markets, and half of them are wrong.
• You see the trade late. By the time a trade appears here, the price it was made at may be gone.
• Size is not conviction. A market maker can move $50,000 through a market with no view on the outcome.
