From Washington to Brussels, the question of who controls artificial intelligence is moving from theoretical debate to concrete policy. US officials are now exploring whether the federal government should take a direct financial stake in AI development, a concept that resonates with European policymakers already grappling with how to balance innovation, sovereignty, and public interest.
Public Investment as a Strategic Tool
The idea of public ownership in AI is not entirely new. History shows that transformative technologies—from the internet to nuclear energy—initially emerged from public research before being commercialised. In the United States, the Defense Advanced Research Projects Agency (DARPA) funded the early internet, while European governments played a central role in developing aerospace and telecommunications infrastructure.
Today, the debate centres on whether governments should go beyond funding research and actually hold equity in AI companies or infrastructure. Proponents argue that such stakes would ensure public oversight, prevent monopolistic control by a handful of Silicon Valley firms, and align development with societal goals like fairness, transparency, and security.
In Europe, the conversation has taken a different but complementary path. The European Union's AI Act, passed in 2024, establishes a risk-based regulatory framework, but some member states and MEPs have called for more direct public involvement. France, for instance, has invested heavily in national AI champions like Mistral AI, while Germany's federal government funds research clusters in Berlin and Munich. The European Commission's proposed 'AI Factories' initiative aims to pool computing resources across the bloc.
European Perspectives on Strategic Autonomy
The US exploration of public stakes comes at a time when European leaders are increasingly focused on technological sovereignty. The war in Ukraine and supply chain disruptions have underscored the risks of relying on non-European providers for critical technologies. As Ukraine's drone revolution has shown, rapid innovation in defence and dual-use technologies can reshape conflict dynamics—and control over AI is central to that shift.
Brussels is also watching US moves closely. The European Commission's executive vice-president for digital affairs, Margrethe Vestager, has repeatedly stressed that Europe must avoid becoming a mere consumer of AI systems developed elsewhere. The proposed 'European AI Infrastructure' plan, still under discussion, could involve joint public investment in cloud computing and data centres, possibly with equity stakes for member states.
However, not all European capitals are aligned. Some northern member states, led by Sweden and the Netherlands, favour a lighter regulatory touch and more private-sector-led innovation. Meanwhile, Brussels is pressing Italy to align its industrial strategy with EU digital goals, highlighting the tension between national priorities and collective action.
Historical Lessons and Future Risks
The push for public stakes in AI draws on a long history of state involvement in foundational technologies. The US government's role in developing the Global Positioning System (GPS) and the European Organisation for Nuclear Research (CERN) in Geneva are often cited as successful models. In both cases, public investment created platforms that later enabled vast private-sector innovation.
Yet critics warn that government ownership can lead to inefficiency, political interference, or stifled competition. The European experience with state-owned enterprises in sectors like energy and telecoms offers cautionary tales. The key, analysts say, is to design governance structures that insulate operational decisions from short-term political cycles while maintaining public accountability.
For now, the US debate remains exploratory. But as AI becomes central to economic competitiveness and national security, the question of public versus private control is unlikely to fade. European policymakers would do well to watch these developments closely—and perhaps to consider how their own traditions of public investment and regulation can shape a distinctly European path forward.
