Kalshi traders put high odds on $4 gas before August

Gas is still below $4 nationally, but traders on Kalshi are betting that threshold gets crossed before July ends. For drivers and investors, the move matters because gasoline prices feed directly into household budgets and can ripple through inflation expectations.

Kalshi traders now assign a 93% probability that the U.S. average gasoline price rises above $4 a gallon this month, according to CNBC. They also see a 63% chance that the average moves above $4.10.

Kalshi is a prediction market, meaning users trade contracts tied to real-world outcomes. In this case, the contract asks where the U.S. gasoline price lands this month, with the result verified by AAA, according to CNBC.

AAA listed the national average at $3.89 on Wednesday, CNBC reported. That was roughly 3 cents above Tuesday’s level.

Why traders are watching oil

Gasoline prices tend to follow crude oil because oil is the main raw material refiners turn into fuel. The relationship is not one-for-one, since taxes, refining costs, distribution and local supply conditions also affect the pump price, but a sustained move in crude can put pressure on retail gasoline.

Oil has climbed for three consecutive days, according to CNBC. U.S. West Texas Intermediate futures for August delivery settled Wednesday at $79.60 a barrel, up 26 cents, or 0.3%, from the previous session. Brent crude futures for September delivery, the international benchmark, ended at $84.95 a barrel, also up 0.3% on the day.

The latest gasoline bets come as the U.S. has resumed strikes on Iran after ending a ceasefire last week, CNBC reported. U.S. Central Command said in a post on X that it launched a second wave of strikes on Iran at 3 p.m. ET Wednesday, after an earlier round that morning.

U.S. Central Command said Wednesday morning that the strikes were meant to reduce military capabilities Iranian forces had used against commercial shipping in the Strait of Hormuz, according to its post on X cited by CNBC. The Strait of Hormuz is a major waterway for global oil shipments, so conflict in the area can affect energy markets if traders expect supply risks to rise.

The $4.50 level still looks unlikely on Kalshi

The national average for gasoline already crossed $4 last month, CNBC reported. The highest level so far this year came on May 21, when AAA’s national average reached $4.56.

Kalshi traders are not pricing in a return to that level by month-end. CNBC reported that traders put the chance of gasoline rising above $4.50 again before the end of July at less than 5%.

CNBC disclosed that it has a commercial relationship with Kalshi, including customer acquisition and a minority investment.
