Recent declines in U.S. regular gasoline prices to near $4.295 per gallon as of mid-October have anchored trader sentiment in Polymarket contracts on whether national averages hit specified thresholds by October 31. Lower RBOB futures near $3.11 per gallon reflect seasonal post-summer demand weakness, refinery utilization near full capacity, and inventories close to five-year averages, while mild late-October weather forecasts and steady domestic supply limit upside volatility. Crude oil benchmarks around $103 WTI and $113 Brent provide the main input-cost floor, though any unexpected inventory draw or geopolitical spike could test resistance near $4.40–$4.50. With resolution imminent on AAA data, market-implied odds price in limited scope for sharp moves before month-end.
