Washington's AI Spending Drives Fastest State GDP Growth in 2026

Washington's real GDP rose 1.1% to nearly $730 billion between Q4 2025 and Q1 2026, per the Bureau of Economic Analysis. At that pace, the state would end 2026 with a 4.5% increase, outpacing the projected 2.1% U.S. growth.

The Seattle metropolitan area hosts major technology firms, notably Amazon and Microsoft, projected to spend about $390 billion on artificial-intelligence infrastructure in 2026. The state's information sector—covering software, cloud computing, digital services, and communications—accounts for most of the growth, and analysts link the GDP acceleration primarily to AI-related capital expenditures.

James McCafferty, co-director of Western Washington University’s Center for Economic and Business Research, noted that Washington excels in the information sector, which includes AI-related activities. Hart Hodges, his co-director, said the state must monitor whether the current quarterly performance reflects a sustainable trend or an outlier.

Hodges warned that a few large data-center projects can disproportionately affect quarterly GDP figures and cautioned against labeling the state’s performance as “unbelievably amazing” or “terrible” without longer-term data. He also expressed uncertainty about the durability of the current growth rate.

The rapid expansion underscores the economic influence of AI investment in Washington and aligns with expectations that the state may outpace national growth if the trend persists.
