This event group covers the UFC Fight Night bantamweight bout between Ethyn Ewing and Rafael Estevam, scheduled for April 4, 2026. Markets span fight outcome (moneyline), method of victory (KO/TKO, submission, decision), fight duration (rounds), and distance completion. All markets reference official UFC determination as the authoritative resolution source.
Polymarket and Kalshi use fundamentally incompatible resolution scopes. Polymarket's moneyline market (Question 10) resolves to '50-50' if the fight ends in a draw, technical draw, no contest, or is canceled/postponed beyond April 18, 2026. Kalshi's moneyline market resolves to 'Yes' if either fighter wins, with no explicit handling of draws or cancellations, creating a logical gap where Kalshi may resolve YES while Polymarket resolves 50-50 for identical outcomes.
Hero Tip:
If you hold positions on both platforms' moneyline markets and the fight ends in a draw or is postponed beyond April 18, 2026, Polymarket will resolve 50-50 (partial loss) while Kalshi's resolution is undefined—potentially leaving you with unhedged exposure. Clarify Kalshi's draw/cancellation rules before the event date or reduce cross-platform exposure.
Critical Divergence Points:
Polymarket:
Outlier on scope and edge-case handling: Polymarket's moneyline market (Question 10) explicitly resolves to '50-50' for draws, technical draws, no contests, or cancellations/postponements beyond April 18, 2026. Quote: 'If the fight is declared a draw or technical draw, ruled a No Contest, not scored, canceled, or postponed beyond April 18, 2026, this market will resolve 50-50.' This creates a three-outcome resolution space (Ewing wins, Estevam wins, or 50-50).
Kalshi:
Outlier on scope and edge-case handling: Kalshi's moneyline market provides only binary resolution logic: 'If Ethyn Ewing wins...then the market resolves to Yes. If Rafael Estevam wins...then the market resolves to Yes.' No explicit resolution path is defined for draws, no contests, or cancellations, leaving the outcome undefined for these scenarios and creating potential settlement ambiguity.
