Story summary

As of mid-October 2026, the U.S. military has spent over $47 billion prosecuting the ongoing war in Iran, according to Pentagon data obtained by Reuters and CBS News. This figure represents a 25% increase from the Defense Department’s July estimate of around $37.5 billion, excluding costs for repairing damage to U.S. bases from Iranian attacks. The latest estimate includes more than $29 billion in replacement munitions, over $6 billion in lost equipment, and additional operational support costs.

The escalating war expenses have strained President Donald Trump’s Republican Party, facing significant political fallout ahead of the November 3 midterm elections, which will determine control of Congress. The war's economic impact has affected global energy prices and diminished public support for both Republican candidates and Trump himself, whose party holds a narrow majority in both chambers.

While not publicly shared by the Pentagon, these financial disclosures highlight the war’s substantial costs and logistical challenges, including strategic inventory shortages due to extensive munitions use. The conflict could continue to cost between $2 billion and $3 billion per month, primarily driven by the need for interceptor missiles to defend against Iranian attacks.
