California gas prices are the highest in the U.S., but there's no proof of price gouging. Here's why.

California has the highest gas prices in the nation, but a state investigation found no evidence that oil companies are price gouging despite years of accusations from state leaders. CBS News California's investigation identified structural factors—rather than illegal corporate practices—as the primary driver of the elevated prices. The finding contradicts the longstanding narrative from California officials who have repeatedly blamed oil industry manipulation for pump prices. Understanding the actual causes matters because it shapes what policy solutions California considers, whether regulation-focused or market-based. The state's unique fuel formulation requirements, refinery capacity constraints, and tax structure are among the factors that typically explain California's price premium over other states.
