# Federal AI Spending Surges as Pentagon Dominates US Government Investment

The Pentagon now commands nearly 99 percent of all federal artificial intelligence contract spending, a concentration so extreme that every other government agency has been reduced to what analysts call a rounding error in Washington's rapidly expanding AI budget.

A sweeping new analysis published by the Brookings Institution on May 18 reveals that federal AI spending has undergone a staggering transformation. The total value of funds obligated to AI contracts reached $7.2 billion in 2026, up 966 percent from $675 million in 2024. Even more striking, the potential value of AI contract awards ballooned to $91.8 billion, an increase of 1,912 percent over just two years.

The numbers tell a story of a government going all-in on military AI. The Department of Defense held 1,319 AI contracts in 2026, up from 657 in 2024 and just 254 in 2022. The department's share of potential contract value surged to $90.7 billion, representing 98.9 percent of all federal AI spending. By comparison, the Department of Health and Human Services and NASA trailed far behind with 134 and 71 contracts, respectively.

The $13.4 Billion Budget Line

The concentration of spending reflects a deliberate strategic choice. The Pentagon's $1.01 trillion fiscal year 2026 budget request includes a record $13.4 billion dedicated specifically to AI and autonomy, marking the first time the Department of Defense has created a separate budget line for these capabilities.

The breakdown reveals where the military sees AI's most immediate battlefield value: $9.4 billion for aerial drones and unmanned aerial vehicles, $1.7 billion for maritime autonomous platforms, $734 million for underwater systems, $210 million for autonomous ground vehicles, and $1.2 billion for software and cross-domain integration. An additional $200 million targets AI and automation technology specifically.

The Brookings researchers, led by James S. Denford of the Royal Military College of Canada, Gregory S. Dawson of Arizona State University, and Kevin C. Desouza, a nonresident senior fellow at Brookings, documented a market that is both maturing and consolidating. Their analysis found that "the Defense Department grew its AI investment to such a degree that all other agencies effectively became a rounding error."

A Maturing but Lopsided Market

The report tracks a clear evolution in how Washington buys AI. In 2022, contracting was dominated by small firms clustered near military bases, a pattern the researchers identified as characteristic of an immature market. By 2024, major players like Booz Allen Hamilton, Palantir, and Accenture Federal Services had entered the field. Now in 2026, large established vendors dominate the contracting space, though 87 percent of firms still hold only one or two contracts.

The Brookings analysis described the overall picture as a market in transition: "the federal government is still in the experimental phase of AI."

Yet the imbalance between military and civilian AI investment raises difficult questions. While the Pentagon's potential contract value exploded by 1,605 percent from 2024 to 2026, HHS saw its AI spending grow from just $27 million to $138 million. NASA's AI spending actually declined slightly, from $47 million to $45 million. The number of federal agencies with AI contracts grew modestly from 23 in 2024 to 28 in 2026, with new additions including the Executive Office of the President, the National Transportation Safety Board, and the U.S. Agency for International Development, each holding a single contract worth under $300,000.

The Strategic Context

The spending surge aligns with the Trump administration's AI Action Plan, released in July 2025, which emphasized deregulation and infrastructure investment to achieve what it called global AI dominance. In January 2026, the Pentagon published its Artificial Intelligence Strategy for the Department of War, establishing seven Pace-Setting Projects spanning autonomous swarms, AI-enabled battle management, and department-wide generative AI deployment.

The defense IT budget as a whole reached $66 billion for fiscal year 2026, a $1.8 billion increase from the prior year, with each military service branch adding to its AI investment. Meanwhile, global AI spending is projected to grow from $1.75 trillion in 2025 to $2.52 trillion in 2026, a 44 percent year-over-year increase, according to Gartner estimates cited in the Brookings report.

What It Means

The federal government's AI spending trajectory raises a fundamental policy question: whether a near-total concentration of government AI investment in defense applications serves the country's broader interests. Healthcare, transportation, environmental science, and dozens of other civilian domains stand to benefit enormously from AI, yet the budget data shows these agencies are barely participating in the government's AI spending boom.

For now, the Pentagon's dominance of federal AI spending appears set to deepen. The market is maturing, the contracts are getting larger, and the strategic imperative behind military AI investment shows no signs of slowing. Whether civilian agencies can carve out a meaningful share of the growing AI budget may be one of the defining policy battles of the years ahead.
