Rainmaker

EventArb
ArbitrageFree cross-platform arbitrage calculator for event contracts. Punch in YES/NO prices for the same event on Polymarket, Kalshi or Robinhood and it does the math each venue's fee schedule implies — whether buying opposite sides locks in a profit, what the spread nets after fees, and the opportunity cost of parking capital until resolution. Supports binary and multiple-choice markets, side-by-side venue comparison, shareable links and free email notifications when opportunities open.
