Europe attracts American brains for the first time since 1945
American applications for the prestigious ERC grants have tripled in two years. 169 young American researchers applied in 2026 compared to 60 in 2024. For established researchers, applications quintupled, rising from 23 to 114. The same phenomenon is occurring in Spain: more than half of the 2026 Atrae grant recipients came from the United States. For the first time since the end of World War II, the flow of brains is reversing between America and Europe.
The Trump administration’s budget cuts to American public research are triggering a scientific exodus to Europe. The European Research Council and several European countries are orchestrating a coordinated attraction policy to close their structural scientific gap. But this geopolitical windfall obliges Europe to deliver on its financial promises.
The essentials
- American applications for ERC grants for young researchers rose from 60 in 2024 to 169 in 2026
- More than half of the beneficiaries of Spain’s 2026 Atrae grant came from the United States
- The NIH and NSF face cuts of 15% and 22% respectively in the 2026 federal budget
- Europe is launching emergency programs endowed with €2.8 billion to attract American talent
Trump cuts trigger American scientific exodus
The National Institutes of Health loses 15% of its 2026 budget, amounting to $6.8 billion. The National Science Foundation sees its funding cut by 22%, losing $2.1 billion. These cuts directly impact the funding of postdoctoral grants and junior research positions. Result: 40% of American laboratories announce job cuts for 2026, according to the American Association for the Advancement of Science.
This bloodletting hits young researchers particularly hard. The NIH’s F32 grants, which finance postdocs, see their numbers divided by three. The NSF’s Early Career Awards fall from 850 to 320 in 2026. “We’re training doctors for Europe,” summarizes Sarah Chen, director of the molecular biology department at Stanford, who has seen six of her best postdocs leave for European laboratories since January.
Basic research bears the brunt. Budgets dedicated to climate change fall by 60%. Astrophysics loses 35% of its funding. Even the life sciences, traditionally spared, suffer cuts of 20% in several fields. This policy contrasts sharply with European investments, which are increasing by 12% in 2026 following the creation of the scientific sovereignty fund.
Europe coordinates the attraction of American talent
Brussels seizes the opportunity. The European Research Council urgently launches the “Welcome US” program endowed with €800 million over two years. Germany activates its Humboldt grants for experienced researchers, France mobilizes its chairs of excellence, Spain triples the allocations of its Atrae program. In total, €2.8 billion is released within six months to attract American talent.
This coordination is organized by specialty. Germany targets engineering sciences and fundamental physics, France focuses on mathematics and artificial intelligence, Italy attracts life sciences researchers. Spain positions itself on climate research, capitalizing on the desertion of American programs in this field. “We no longer compete among Europeans. We’re sharing American talent,” explains Maria Leptin, director of the European Research Council.
Procedures are accelerating. Application deadlines for ERC grants drop from eight months to four. Germany allows American researchers to begin their work before their visa is definitively validated. France creates a single window for administrative procedures. These simplifications contrast with the growing bureaucratization of the American system, where obtaining federal funding now takes an average of 18 months.
European universities modernize to compete
This race for talent forces Europe to modernize its research structures. Heidelberg University creates turnkey English-language laboratories to welcome American teams. The Swiss Federal Institute of Technology Zurich recruited 15 American researchers in six months and adapted its evaluation procedures to international standards.
Salaries align with American standards. A European postdoc now earns an average of €45,000 per year compared to €35,000 in 2024. Associate professors see their compensation increase by 25%. Germany removes duration limits on research contracts, long criticized by American scientists accustomed to the stability of the tenure system.
Equipment follows suit. The Max Planck Institute invests €400 million in new equipment to attract American laboratories. French INSERM unlocks €200 million to modernize its technology platforms. This equipment race benefits European companies: Zeiss sees its research microscope sales jump by 40%, Thermo Fisher Europe wins contracts worth €150 million.
Europe’s strategic sectors strengthen
European artificial intelligence benefits directly from this exodus. Thirty American researchers specializing in AI have joined European laboratories since January, mainly in Germany and the Netherlands. These recruitments partially compensate for American dominance in cloud infrastructure by strengthening European fundamental research capabilities.
European climate research closes its gap. Europe welcomes 85 American climatologists in 2026, more than the previous five years combined. These recruitments strengthen the Copernicus Climate Change Service and IPCC laboratories based in Europe. Research on renewable energies gains scientific credibility against American fossil fuel lobbies.
European biotechnology becomes denser. Forty-two life sciences researchers have crossed the Atlantic, primarily to Germany, Switzerland, and the Netherlands. This migration compensates for the historical weaknesses of the European ecosystem in molecular biology and genomics. European biotech startups see their valuation increase by 30% thanks to these new skills.
Europe must now deliver on its budget promises
This attraction policy is expensive. The €2.8 billion promised represents a 25% increase in European research budgets. Germany taps into its budget surpluses, France borrows an additional €400 million, Spain postpones infrastructure investments. This escalation raises questions about medium-term financial sustainability.
National parliaments are beginning to question these expenditures. The German Bundestag requests an audit on the effectiveness of recruitments. The French Senate worries about budget drift in the excellence program. These political tensions remind us that Europe must prove the return on investment of this talent attraction policy.
European industry is watching the results. Technology transfers from laboratories to businesses remain slower than in the United States. Patents filed by European laboratories advance 15% in 2026, but this increase does not yet compensate for historical productivity gaps. Europe must now transform this talent attraction into an industrial competitive advantage.
A window of opportunity lasting four years at most
This reversal of brain drain remains fragile. American cuts are part of a four-year political mandate. A change in administration could massively relaunched American public research and stem the exodus to Europe. American universities retain their structural advantages: higher salaries, entrepreneurial ecosystem, administrative simplicity.
Europe has a four-year window to durably anchor these talents on its territory. This requires creating an ecosystem for valorization competitive with that of the United States. The first signs are encouraging: fifteen American researchers who arrived in 2025 have already created their European startup. But this dynamic remains marginal compared to the 3,000 technology companies created each year by American doctoral students in the United States.
The battle for brains is now being fought on Europe’s capacity to retain these talents beyond the American political crisis. Europe has a historic chance to reduce its scientific gap. It must now prove that it can transform this geopolitical windfall into a lasting advantage.
