Business R&D expenditure in the US, expressed as a percentage of GDP, is forecasted to gradually increase from 2.86% in 2024 to 2.96% in 2028. This steady rise reflects ongoing investment in innovation and the technological sector. Given that in 2023 it stood at an actual 2.83%, the projections suggest modest year-on-year growth.

Future trends to watch include:

The influence of government policies on research funding and tax incentives.
Emerging technology sectors such as AI and biotechnology driving increased investment.
Global competition, which may affect domestic R&D strategies and expenditures.
