A sudden AI ‘kill switch’ in the US has sparked a tech sovereignty reckoning in Europe, as the EU and UK scramble to match state-led industrial policy and close a $2tn revenue gap.
The US Department of Commerce issued an emergency directive on 12 June 2026, forcing the AI startup Anthropic to suspend foreign nationals from using its ‘Claude Fable 5’ model. This swift move, with no exemptions for allies, marked a decisive moment in the US’s ability to wield what’s known as an AI ‘kill switch’. This refers to the government’s capacity to instantly disable or restrict access to a foreign AI model, effectively limiting its use and potentially holding foreign companies hostage.
State-led industrial policy in focus
The EU and UK have responded by rolling out a series of tech sovereignty measures aimed at bridging their respective revenue gaps with the US. This includes strengthening regulations on AI exports, creating national champions through strategic investments, and promoting European AI startups. One key initiative is the EU’s proposed ‘European Data Act’, which would grant citizens more control over their personal data and create a unified data market.
Europe’s tech sovereignty challenge
EU Commissioner Thierry Breton has acknowledged that the bloc faces a ‘sovereignty gap’ of around $2tn in annual revenue compared to the US. Closing this gap will require sustained investment in AI, data infrastructure, and national champions. European governments must weigh the need for state-led industrial policy against concerns around over-regulation, which could stifle innovation and entrepreneurship.
As the tech landscape continues to shift, one thing is clear: the US’s AI ‘kill switch’ has set off a global game of catch-up. European policymakers must now decide whether state-led industrial policy is the key to bridging the revenue gap or if a more hands-off approach will unlock greater innovation and success.
What this means: The EU and UK’s response to the US AI ‘kill switch’ marks a significant turning point in the global tech sovereignty debate. As Europe seeks to close a $2tn revenue gap, state-led industrial policy will likely play a central role in shaping the future of AI development and deployment on the continent.
