Polymarket uses intraweek price extrema (any 1-minute candle HIGH/LOW during April 13-18, 2026), while Kalshi uses a single settlement price on April 17, 2026. These measure fundamentally different outcomes: Polymarket captures whether a price level is touched at any point; Kalshi captures only the closing price on a specific day.
Hero Tip:
If you trade Polymarket, you win if WTI ever touches your strike during the week—volatility works in your favor. On Kalshi, you win only if the settle price on April 17 lands in your band—directional accuracy matters more than range. Polymarket HIGH/LOW markets are broader (easier to hit); Kalshi bands are narrower (require precise settlement). Do not assume correlated outcomes across platforms.
Critical Divergence Points:
Polymarket: Resolves YES if any 1-minute candle for the Active Month WTI futures contract reaches or exceeds (for HIGH) or falls to or below (for LOW) the strike price at any point during the week of April 13–18, 2026. Resolution source is Pyth 1-minute candle data, with CME daily high/low as fallback. Quote: 'This market will resolve to Yes if, at any point during the week of April 13 2026, any 1-minute candle for the Active Month of WTI Crude Oil futures has a final High price equal to or above the listed price.'
Kalshi: Resolves YES if the front-month WTI settle price on April 17, 2026 (Friday, end of week) falls within a specific $1.00 band (e.g., $97.00–$97.99, $100.00–$100.99, etc.). All 15 bands collectively cover the range $91.00 and above, ensuring exactly one band resolves YES. Resolution source is the official front-month settle price on April 17, 2026. Quote: 'If the front-month settle price for a barrel of West Texas Intermediate oil on April 17, 2026 is between $97.00 and 97.99, then the market resolves to Yes.'
