U.S. Economy Poised to Reaccelerate in 2026 as Fiscal Stimulus and AI Investment Intensify; California Growth Outpaces Nation Despite Ongoing Employment Weakness

Income tax cuts, AI infrastructure expansion and moderating tariff pressures shift risks from labor market cooling toward potential overheating

LOS ANGELES, March 4, 2026 /PRNewswire/ — The spring 2026 UCLA Anderson Forecast for the United States and California signals a meaningful shift in economic momentum since late 2025. In December 2025, the Forecast anticipated an economy “muddling through” amid tariff shocks and labor market stagnation. Three months later, the balance of risks has shifted toward reacceleration in 2026, fueled by income tax cuts, expansion of fiscal stimulus and sustained artificial intelligence investment.

While aggregate indicators point toward stronger growth, the Forecast also highlights continued structural imbalances. Nationally, productivity gains and capital spending remain strong, even as segments of the labor market continue to recover unevenly. In California, output growth continues to exceed national performance, but payroll employment remains subdued, underscoring the divergence between production and hiring.

The National Economy

The U.S. economy in 2025 was marked by tariff hikes, supply chain disruptions, reduced immigration flows and a record-setting 43-day federal government shutdown. Despite these headwinds, GDP expanded 2.2% for the year, remaining above the Congressional Budget Office’s long-run neutral growth estimate.

Looking ahead, 2026 is expected to bring stronger growth. As the national report states, “With the immediate impact of tariff hikes largely realized, the stage is set for substantial income tax cuts to stimulate an economy already buoyed by lower interest rates and massive capital expenditures in AI.”

The Supreme Court’s February ruling invalidating tariffs imposed under the International Emergency Economic Powers Act reduced the overall tariff burden. However, the report notes that “tariff uncertainty remains a permanent fixture of the economic landscape.” While some duties have been rolled back, substantial tariffs remain in place, and most of their costs were borne domestically and largely passed on to consumers.

Capital expenditures on AI infrastructure are projected to reach roughly $660 billion in 2026 — approximately 2% of GDP. Hyperscalers continue to lead investment, though emerging constraints in energy supply, grid transmission capacity and chip depreciation costs may moderate the pace of expansion over time.

The most significant policy shift entering 2026 is fiscal expansion through the One Big Beautiful Bill Act. Retroactive income tax provisions are expected to increase refunds and boost disposable income, while new incentives such as bonus depreciation are projected to stimulate private investment. Combined fiscal effects are estimated to add between 0.5% and 1% to GDP, with additional stimulus possible from refunded tariff revenues.
