Intro

This market tracks whether the average regular gas price in the United States will exceed $3.90 on August 31, 2026, according to AAA data. On Kalshi, the current probability that prices will be above this threshold stands at 99.0%. The market will resolve based on AAA's reported average gas price for that date. Watch for the final AAA gas price report on August 31, 2026, which will determine the outcome.

Kalshi

Resolution is determined by the average regular gasoline price for the United States on August 31, 2026, according to AAA's official data. Each market resolves to Yes if the average price is strictly greater than its specified threshold ($2.50, $2.60, $2.70, $2.80, $2.90, $3.00, or $3.10 per gallon). The resolution uses AAA's published average for that specific date, with Yes outcomes triggered only when prices exceed the stated level rather than meeting or falling below it.

Frequently asked questions

The US gas prices market dashboard on Kalshi tracks real-time odds and historical price movements for the US gas prices market, allowing traders to monitor how the prediction community expects pump prices to move through August 2026. The interface displays current implied probabilities for different price ranges, along with 24-hour trading volume and cumulative liquidity. This live data helps participants gauge consensus sentiment on fuel costs and identify shifting expectations as new economic data or energy news emerges.

Prediction market odds often diverge from traditional analyst forecasts because they reflect real-money incentives and crowd wisdom rather than institutional models alone. Traders in this market are betting their capital on where gas prices will actually land, which can lead to faster price discovery than consensus surveys. When major economic reports, geopolitical events, or refinery disruptions occur, market odds typically shift before analysts publish revised estimates, making prediction markets a complementary signal to conventional energy forecasts.

On Kalshi, this market is priced through a continuous order-book mechanism where traders buy and sell shares representing different price outcomes. On Kalshi, prices reflect that venue's order book, liquidity, and how traders price the outcome right now. Each contract reflects the probability that gas prices will fall within a specified range by the resolution date. As new information enters the market—such as crude oil movements, supply disruptions, or macroeconomic shifts—traders adjust their positions, and the bid-ask spread tightens or widens accordingly, creating a dynamic price discovery process.

This market resolves around Aug 31, 2026, with the outcome confirmed once the event is verifiable from credible public reporting. The resolution will reflect actual US gas prices during August 2026, measured against the price thresholds defined in the contract terms. Traders holding the correct outcome receive their payout once the data is finalized and the market is officially settled.

Major catalysts for this market include crude oil price swings, OPEC production decisions, US refinery capacity changes, geopolitical tensions affecting supply, Federal Reserve interest rate policy, and seasonal demand fluctuations. Unexpected supply disruptions—such as hurricanes in the Gulf of Mexico or pipeline outages—can trigger sharp repricing. Additionally, shifts in global economic growth expectations and the US dollar strength will influence energy costs. Traders monitor weekly petroleum inventory reports and real-time fuel price data as leading indicators of where the market will ultimately settle.
