Reddit and Hacker News users claim AI and bot arbitrage profits on Polymarket
Reddit and Hacker News users have posted claims of running profitable arbitrage bots on Polymarket. One Reddit user under the handle @b00k13 claims $8,300 in profits over three months from a cross-venue arbitrage bot that exploited lagging prices relative to sportsbook odds, and separately posted verified profit-and-loss data from January to April citing insufficient market-maker competition. Reddit user says an AI-generated Python bot produced roughly $5,000 with minimal manual coding. A Hacker News user detailed a strategy scraping sportsbook odds, removing vig, and posting limit orders on Polymarket esports markets, though without profit figures. None of the posts included full technical methodologies or independent verification.
Polymarket's order books are shallow enough that retail bots can still extract cross-venue alpha against sportsbook lines. Wintermute's formal entry into automated liquidity on the same venue means these opportunistic strategies face a shrinking window before institutional market makers close the spread.
Joins Wintermute's automated Kalshi-Polymarket liquidity deployment and Binance Wallet's prediction-markets API as fresh evidence that algorithmic trading bots are moving from experimental side projects into live, cross-venue arbitrage on prediction-market platforms.
