The R&D budget for Planet and Infrastructure as a percentage of GDP in the US is forecasted to decline from 0.09% in 2024 to 0.081% by 2028. This gradual decrease reflects a continuous, albeit modest, reduction over this period. The average annual decrease from 2024 to 2028 is around 2.58%, highlighting a subdued prioritization in R&D fiscal allocation relative to GDP growth.

Future trends to watch for:

Potential shifts in government policy that may increase the R&D budget allocation.
Innovation demands in infrastructure modernization and environmental technologies which might drive a revision in budget priorities.
Impact of macroeconomic conditions on fiscal policy relating to R&D investments.
