In 2023, the US government expenditure on R&D was at 0.29% of GDP. The forecast for the subsequent years positions the expenditure at 0.28% of GDP for 2024 and 2025, followed by a slight dip to 0.27% through 2026 to 2028. Over the five-year projection period, the Compound Annual Growth Rate (CAGR) is slightly negative, indicating a minimal decline in R&D spending as a percentage of GDP.
Future trends to watch for include potential shifts in government priorities that could alter R&D funding, particularly in emerging sectors such as technology and clean energy, which might influence overall expenditure levels.
