Executable arbitrage candidates

VoxOdds buys opposite sides of the same fingerprint-pinned binary outcome, matches the contract count, walks both live ask books, and includes estimated taker fees. A row appears only when the captured all-in cost is below the common settlement payout.

Exact reviewed binary pairs; equal whole-contract opposite sides; live ask depth; estimated taker fees and conservative Kalshi rounding. These are unfilled arbitrage candidates, not guaranteed trades. Cross-venue orders are non-atomic, and prices, depth, eligibility, balances, and venue previews can change before both legs fill. Sportsbook stakes respect provider-reported limits when available; missing limits are never interpreted as guaranteed capacity. 18+ only. Gamble responsibly. Prediction-market JSON · Sportsbook JSON
