May 21, 2026 did set a record — for the Trump presidencies, at $4.56 a gallon. It was not an all-time record: June 2022 averaged over $5.00 nominal, and adjusted for inflation 2012 gas cost about $5.07 in today’s dollars. Prices have since fallen back to about $3.84.
The national average peaked at $4.56 per gallon on May 21, 2026 — the highest at any point during either of President Trump’s terms, which is the true kernel that gave the claim life. But “all-time record” fails on both measures that matter. In nominal dollars, June 2022 remains the record at over $5.00 a gallon. Adjusted for inflation, 2012’s $3.62 average works out to roughly $5.07 in today’s dollars — the real-terms record. By July 2, 2026, the national average had fallen back to about $3.84. A five-year high got marketed as a forever high.
