As artificial intelligence reshapes industries, M&A activity in the AI sector is surging—but so is regulatory scrutiny. Companies looking to secure a competitive edge through acquisitions must now navigate a complex web of global antitrust and national security rules, making early risk assessment critical to deal success.
The regulatory landscape is evolving rapidly. The EU AI Act, which came into force in August 2024 and will be fully enforceable by 2027, sets strict rules on transparency and accountability for AI systems. In the US, a 2025 executive order under the Trump administration and a patchwork of state laws in Utah, Colorado and Texas have created layered AI-specific compliance challenges.
Against this backdrop, AI deals are facing deeper regulatory investigation. Antitrust authorities in the US, Europe and the UK are watching closely for market consolidation risks in a sector increasingly dominated by a handful of players with control over computing power, data and talent. In the US, the Department of Justice is probing Nvidia, while the FTC is examining Microsoft’s investment in OpenAI and its recruitment of staff from Inflection AI.
Attention is not limited to headline acquisitions. Regulators are also scrutinising less obvious deal structures such as acquihires, equity investments and strategic partnerships that provide governance or exclusivity. The UK’s Competition and Markets Authority and Germany’s Federal Cartel Office have both opened and, in some cases, closed investigations into such arrangements, while the US remains active in this space.
Alongside competition concerns, national security is now a major factor in AI M&A. In the US, outbound investment screening under a “reverse CFIUS” framework is restricting capital flow to countries such as China, especially where deals involve sensitive technologies or government data. New policies aim to protect strategic capabilities while streamlining allied investments, but investors must still expect extended timelines and higher compliance costs.
To manage these challenges, firms are adopting smarter deal structures—such as non-controlling investments, contractual limits on data access and carve-outs for sensitive technologies. These tactics are designed to reduce regulatory friction while preserving strategic value.
Policymakers are balancing two imperatives: guarding national and economic security, and ensuring the AI sector remains open to innovation and competition. There is growing debate over whether regulatory fragmentation could hinder the scale needed for advanced AI development, or instead enable more dynamic market entry for emerging players.
For companies and investors, the message is clear: success in AI M&A now demands an integrated legal and strategic approach. Engaging early with antitrust and national security experts is essential to structure deals that can withstand global scrutiny. As the UK seeks to position itself as a leader in AI, it must shape a regulatory environment that balances innovation, security and competitive fairness—ensuring it remains an attractive destination for investment and technological leadership.
