Upvote ArbBets Share 1 / 2 ## About ArbBets ArbBets scans prediction markets across Polymarket, Kalshi, and Opinion to find price discrepancies on the same event, listing over 990 markets and surfacing more than 100 arbitrage opportunities daily. Each match shown on the site pairs a Kalshi and Polymarket listing for the same question, such as election outcomes, sports championships, or political appointments, alongside the percentage spread between them. Because arbitrage trades against the price gap itself rather than the eventual outcome, the underlying result of the market does not affect the trade the way it would for a directional bettor. The tool presents these matched market pairs with fee-adjusted ROI figures, so the spread shown accounts for trading costs rather than just raw price differences. Listings update on a delay and cover a wide range of categories, from national elections and legislative races to entertainment, sports titles, and corporate events like IPOs. ArbBets also offers an arbitrage betting API for automating detection or execution, with paid plans starting at $59/month, alongside a free tier for browsing available opportunities. It suits traders who already understand cross-platform arbitrage mechanics and want a running feed of matched markets rather than a tool that explains the strategy from scratch.

It is listed in the LaunchPoly directory, where it was added on December 5, 2025 and currently has 23 community votes this round.
