Frequently asked questions

Has this market been an arbitrage?
Yes — 25 separate windows where buying the cheaper side on each venue cost less than $1 after both fees, first on Aug 18, 2026 and most recently Sep 17, 2026. The largest net edge was 3.98% and windows averaged 258 minutes.
Do both contracts resolve the same way?
The pair was confirmed as the same question (AI-matched · 98%). That judgment covers the headline question; resolution rules can still differ in edge cases (sources, timing, ties). Read both venues' rules before treating a gap as risk-free.
What do the fees do to the gap?
Kalshi charges takers 7% × price × (1 − price) per contract; Polymarket charges its category rate on the same curve. Near 50¢ that is roughly 1.75¢ per contract on Kalshi and 1–1.75¢ on Polymarket, so a visible gap of 3–4¢ is typically the minimum before anything is left.
