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.

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.
