The US government and the AI industry are both betting on debt. They are drawing from the same pool.

US Debt Crosses 100% of GDP as Big Tech's AI Buildout Competes for Capital Markets

TL;DR:

US public debt has exceeded 100% of GDP for the first time since World War II, reaching 100.2% at the end of March. This comes as Big Tech commits $660 billion to $690 billion in AI capex for 2026, further straining global capital markets already absorbing massive Treasury issuance.

The United States government now owes more than it produces. According to data from the Bureau of Economic Analysis (BEA) released on April 30th, public debt stood at $31.27 trillion in March, while nominal GDP was $31.22 trillion, resulting in a debt-to-GDP ratio of 100.2%. This is a first since World War II, with the wartime peak reaching 106% in 1946.

Maya MacGuineas, president of the Committee for a Responsible Federal Budget, highlighted the contrast: "the 1946 debt was borne from a seismic global conflict," while today's is the result of "a total bipartisan abdication of making hard choices."

Total gross national debt, including intragovernmental obligations, has already surpassed $39 trillion. That’s roughly $114,000 per American or $289,000 per household.

The government will spend approximately $1 trillion on net interest in fiscal 2026, surpassing the defense budget.

The Congressional Budget Office (CBO) projects debt held by the public to reach 108% of GDP by 2030 and 120% by 2036. The deficit for fiscal 2026 is projected at $1.9 trillion, growing to $3.1 trillion by 2036. Currently, the government spends $1.33 for every dollar of revenue collected.

Interest payments, already surpassing defense and Medicare as the second-largest federal expense, are expected to hit $2.1 trillion annually by 2036, based on the CBO’s baseline scenario with no changes in current law.

The recently passed One Big Beautiful Bill Act will worsen these projections before any potential improvement mechanisms kick in.
