The government-financed gross domestic expenditure on R&D in the US is recorded at 0.57% of GDP in 2024, with a declining trend expected over the following years: 0.56% in 2025, 0.55% in 2026, 0.53% in 2027, and 0.52% in 2028. The year-on-year changes indicate a consistent decrease. The forecast suggests a continuous reduction, likely reflecting budget constraints or a shift towards private sector-led R&D initiatives.

Future trends to watch for:

Potential changes in governmental priorities or policies affecting R&D funding, especially in response to technological advancements or economic conditions.
Impact of geopolitical factors on federal R&D expenditure decisions.
Adaptations in R&D strategies to align with climate change and sustainable development goals.
