Reddit and Hacker News users claim AI and bot arbitrage profits on Polymarket
Multiple Reddit and Hacker News users posted claims of generating automated arbitrage profits on Polymarket in early June. One Reddit user under the handle @b00k13 reported $8,300 in cross-venue arbitrage over three months by exploiting lagging Polymarket prices against sportsbook odds, sharing verified profit-and-loss data from January to April. Reddit user claimed roughly $5,000 in profit from an AI-generated Python bot that required minimal manual coding, with a public wallet but no technical details disclosed. A separate Reddit user sought community advice for building an expected-value bot comparing Polymarket prices against consensus sportsbook pricing. A Hacker News user described an arbitrage bot scraping sportsbook odds, removing vig to derive fair prices, and posting limit orders on Polymarket esports markets, though without citing profit figures.
Polymarket's insufficient market-maker competition is now being systematically harvested by retail bots, tightening spreads but exposing unsophisticated automated strategies to institutional execution speed. Every public arbitrage template published on Reddit or Hacker News accelerates the arms race that Wintermute's quant infrastructure already dominates.
