Polymarket has launched a new prediction market for May WTI crude oil prices, offering multiple price tiers from $20 to $150. The market uses a unique settlement rule where a "Yes" outcome is determined if the highest closing price of any 1-minute K-line of the nearest-month WTI crude oil futures contract meets or exceeds the predicted price. This differs from the June settlement rules, which require the settlement price on the trading day to be higher than the predicted price for a "Yes" outcome. Odaily Seer is actively monitoring these prediction markets for price changes.
