More than 85% of wallets on Polymarket are currently unprofitable, which suggests many retail traders act as exit liquidity.

Algorithmic wallets and latency arbitrage

Polymarket has attracted algorithmic trading; fourteen of the top twenty leaderboard wallets are now operated by bots.

• $313 → $3M: a bot exploits a 3–10 second price lag between Binance and Coinbase feeds versus Polymarket.
• Trades yield 0.5–4.8% per event; with over 200 daily trades and a 98% win rate, returns compound rapidly.
• $1 → $3.7M: another strategy reduces broadcast latency from 15–40 seconds to about 100 ms using co-located VPS access.
• $1K → $100K: weather arbitrage uses airport station data such as LaGuardia and Love Field, not city-center temperatures.

These bots aggregate METAR/TAF, Open-Meteo and GFS, convert readings into event probabilities and trade when Polymarket prices diverge.

Insider activity and documented cases

The Harvard-Columbia forum published the first systematic study documenting insider trading on Polymarket involving military officers and government officials.

• One wallet converted $38,500 into $485,000 surrounding a Maduro-related market.
• A wallet opened a position at 17% probability seventy-one minutes before U.S. strikes on Iran and later realized $553K.
• Six newly created wallets earned $1.2M in February 2026 trading the contract "US strikes Iran by Feb 28?" by buying YES at $0.10.
• A wallet correctly predicted 22 of 23 top Google search queries for 2025.
