If current congressional plans go forward, the US federal deficit will be about 7% of GDP.

Judge the prediction against the US federal deficit as a share of GDP for fiscal year 2026 (Oct 2025–Sep 2026), the first full fiscal year after the June 2025 statement and the 2025 budget reconciliation law. Use the official figure, i.e. the Treasury's final monthly statement or CBO's FY2026 budget review, divided by nominal GDP. If both are published, use CBO's percentage. 'About 7%' is a rough figure. True: 6.5% to 7.5% inclusive. Mostly true: 6.0% to under 6.5%, or over 7.5% to 8.0%. Mostly false: 5.5% to under 6.0%, or over 8.0% to 8.5%. False: below 5.5% or above 8.5%. If Congress materially reversed the plans in question before FY2026, the claim's condition did not hold; note this, but still judge against the reported figure.

Set before the research began.

1. E1 CBO: FY 2026 Budget Deficit Totaled $2 Trillion - AAF American Action Forum · 8 October 2026

   “As a share of the economy, the FY 2026 deficit was an estimated 6.2 percent of gross domestic product (GDP), 0.3 percentage points of GDP higher than the 5.8 percent of GDP FY 2025 deficit.”

2. E2 Monthly Budget Review: September 2026 Congressional Budget Office · 8 October 2026

   “The federal budget deficit totaled $2.0 trillion in fiscal year 2026, CBO estimates, $218 billion more than the deficit recorded in fiscal year 2025.”

3. E3 U.S. Treasury: FY 2026 Deficit Totaled $2 Trillion - AAF American Action Forum · 18 October 2026

   “As a share of the economy, the FY 2026 deficit was an estimated 6.1 percent of gross domestic product (GDP), 0.3 percentage points above the 5.8 percent of GDP FY 2025 deficit.”

4. E4 [PDF] Final Monthly Treasury Statement U.S. Department of the Treasury, Bureau of the Fiscal Service · 30 October 2026

   “This issue includes the final budget results and details a deficit of $1.992 trillion for Fiscal Year 2026.”

E1 summarises CBO's September 2026 Monthly Budget Review and puts the FY2026 deficit at about 6.2% of GDP. E3, based on Treasury's final figures, gives about 6.1%. E2 and E4 confirm a deficit of roughly $2.0 trillion ($1.992 trillion per Treasury). The criteria say to use CBO's percentage when both are published, and either figure falls in the 6.0% to under 6.5% band, which they define as mostly true against a prediction of about 7%.
