What happened
According to the US Congressional Budget Office (CBO), the first five months of the Iran war cost the United States $38 billion.
The figure was reported by Cailian Press and carried by East Money Information.
Why it matters
The CBO's estimate provides an official price tag for the early phase of the conflict, giving lawmakers and the public a concrete reference point for the fiscal burden of the war.
Because the number covers only the opening five months, it suggests the total cost would continue to rise if operations persist, though the source does not project future spending.
