Research and development expenditure in the US - Data and Analysis (1980-2032)

Research and development (R&D) expenditure is estimated to reach $901.1 billion in 2026, representing a 4.1% increase from the previous year. Advances in artificial intelligence and other emerging technologies have driven renewed interest in innovation, keeping R&D investment on an upward trajectory. While budgetary constraints have persisted due to prolonged high interest rates and lingering recessionary fears, the potential for AI-driven cost savings and windfalls have prompted businesses to keep R&D investment high.R&D expenditure followed a healthy upward trend from 2021 to 2026, increasing at a compound annual growth rate of 3.8%. Spending rose sharply in 2021 with an 8.0% increase, bringing investment above pre-pandemic levels as companies resumed projects paused during lockdowns and responded to new market opportunities created by digital transformation. However, momentum slowed in 2022 and 2023 as inflation surged and macroeconomic uncertainty grew. Businesses responded by tapering R&D investments, particularly in sectors most sensitive to consumer demand. Additionally, rising interest rates increased the cost of borrowing, further constraining capital spending. While R&D activity in manufacturing, which represents a substantial portion of private investment, continued to track closely with shifts in consumer and global trade dynamics, non-manufacturing sectors such as technology and professional services saw steadier commitment to R&D but remained indirectly exposed to broader business cycle fluctuations. Throughout the period, the share of private versus government funding remained stable, with private enterprises contributing approximately 90.0% of total expenditures. The persistent lack of significant public investment limited the counter-cyclical effect that government funding could provide, reinforcing the close correlation between R&D spending and overall corporate profitability.Technological innovation remained a critical macro trend, driving sustained investment even as challenging economic conditions persisted. Artificial intelligence, automation, and digitalization efforts across multiple industries have proven essential to maintaining competitive advantages and prompted companies to prioritize innovation despite resource constraints. Over the five years to 2026, these factors have underpinned the overall upward movement in R&D spending, as businesses aimed to capture new market segments and improve operational efficiencies in an evolving economic landscape.
