Any shift away from those programmes toward a single initiative carries risks that scientists have long flagged:

• Less room for curiosity-driven research, which has historically produced unexpected breakthroughs.
• Concentration of funds in one priority area, leaving other disciplines with shrinking budgets.
• Uncertainty for early-career researchers, who depend heavily on core grant lines to launch their labs.

Because the reporting is based on planning documents rather than a final, published budget, the scope of the cuts could still change. Budget proposals at federal agencies routinely pass through internal review and congressional approval before taking effect.

How does NSF funding normally work?

Congress sets the NSF's overall budget each year. The agency's directorate structure then divides that money among disciplinary divisions — for example, mathematical and physical sciences, or biological sciences — which run competitive grant competitions.

Rerouting money from those divisions to a cross-cutting initiative would represent a structural change in that process. Previous administrations have also created priority programmes at the NSF, but scientists and policy watchers often debate whether such programmes come with new money or simply reallocate existing funds.

In this case, the reported plan appears to follow the second path: funding the White House initiative by trimming the core science portfolio rather than by receiving a budget increase.

What happens next?

The plan's fate depends on several steps that remain ahead. Agency leadership would need to finalise its budget request, the White House would incorporate it into its overall spending proposal, and Congress would ultimately decide appropriations.

Researchers and university administrators will likely watch the coming budget cycle closely. If the cuts to core programmes materialise, grant success rates — already competitive — could fall further in affected fields.

For now, the story rests on planning documents described by Nature. No final figures, timelines or programme-by-programme breakdowns have been confirmed publicly. Scientists seeking certainty about their own funding will have to wait for the formal budget release.
