The Physical AI Opportunity: How UK Companies Can Win While US Platforms Lock Out Europe
 
How do you scale a European DeepTech company when your biggest market is closing its doors?
 
For most UK and European founders, the path to venture scale has always required accessing US customers for revenue growth. Whether you're building autonomous robots in Cambridge or AI semiconductors in Munich, the conversation with Series A investors inevitably turns to the same question: "What's your US market strategy?"
 
It's not just about revenue potential - though the US represents 41% of global tech spending. It's about proving you can compete on the world's most competitive stage.
 
But 2025 has fundamentally changed this playbook. The US isn't just becoming more selective about foreign technology - it's actively building infrastructure designed to exclude non-American AI companies from its most valuable segments.
 
When President Trump declares that "Perhaps most importantly, winning the AI race will demand a new spirit of patriotism and national loyalty in Silicon Valley and long beyond Silicon Valley" and announces $500 billion in domestic AI infrastructure, European founders face a stark reality: the market you've been planning to scale into is systematically locking you out.


The New Protectionist Reality: "Full-Stack AI Export Packages"

The strategic intent became crystal clear when President Trump addressed the "Winning the AI Race" summit attended by the great and the good of US tech last week. His message was unambiguous: "We need US technology companies to be all in for America" adding "Many of our largest tech companies have reaped the blessings of American freedom while building their factories in China, hiring workers in India, and slashing profits in Ireland... those days are over."
 
The Trump administration's AI Action Plan makes this strategy operational: the government will partner with US tech companies to make "full stack AI export packages" - AI models, hardware and software - available to American ally countries. That's in an effort to make US technology the global standard.
 
This isn't traditional protectionism through tariffs or quotas. It's technological sovereignty through ecosystem control. When the US exports complete AI solutions - from foundation models to cloud infrastructure to compliance frameworks - there's no room for European components or competitors.
 
You're not just competing against American companies; you're competing against American economic statecraft.

As White House AI Czar David Sacks explained during the All-In podcast's coverage of the summit: "It's a global competition now to lead in artificial intelligence. AI is a revolutionary technology that's going to have profound ramifications for both the economy and for national security, so it is just very important that America continue to be the dominant power in AI."
 
Consider the Stargate Project: $500 billion to build 20 "AI factories" across the United States, each one a specialised complex for training and running foundation models. Oracle's Larry Ellison describes these not as data centres but as manufacturing facilities for artificial intelligence - infrastructure designed to make American AI platforms the default global choice.
 
For UK founders who've built business plans around US market penetration, this creates a significant challenge. The market you're targeting isn't just competitive - it's actively designed to exclude you.

However, the UK's position is markedly better than continental Europe's. While the EU has agreed to 15% tariffs on semiconductors and other tech exports to the US, the UK secured preferential treatment with just 10% baseline tariffs, reflecting the enduring "special relationship" between London and Washington.
 
 
The VC Reality Check: US Market Access as Funding Prerequisite
 
This protectionist shift creates a cascading problem for European founders seeking growth capital. Venture investors - even European ones - have structured their returns around companies that can access US markets. When Atomico or Accel evaluate a UK AI startup, they're not just assessing technology; they're assessing scalability to American market sizes.
 
But if US market access becomes structurally difficult for non-American AI companies, what happens to the European VC value proposition? Can you still raise a £50 million Series B if your addressable market has suddenly shrunk by 40%?
 
The answer depends entirely on which segments of the AI market you're targeting. Not all AI categories face the same protectionist barriers, and not all require US market access for venture-scale returns. The key is understanding where European companies can still compete - and where they can't.
 
 
Decoding the AI Market Structure: Where Europe Can Still Play
 
Pitchbook's recent analysis of AI trends for 1Q25 reveals a market with dramatically different dynamics across four key segments:
 
Horizontal Platforms captured 67.6% of value ($49.8 billion) with $117.1 million average deal sizes in 1Q25. This includes foundation models, AI automation platforms, and core AI infrastructure. Despite the capital intensity, 1 in 4 companies that have raised capital in this segment (2,027 out of 8,313) are European - but they're concentrated in specialised subcategories like multilingual processing and regulatory-compliant automation.
 
Vertical Applications attracted 63.8% of deals but only 26.1% of value, with $18.8 million average deal sizes. These are industry-specific AI solutions - spanning consumer applications, healthcare IT, financial services, industrial automation, and transportation - built on top of horizontal platforms.
 
AI Semiconductors captured just 3.3% of value ($2.5 billion) across 4.1% of deals, with $37.8 million average deal sizes. Despite all the chip shortage rhetoric, this remains a specialist market.
 
Autonomous Machines secured 3.0% of value ($2.2 billion) across 5.7% of deals, with $24.6 million average deal sizes. This is where AI meets physical reality - robotics, industrial automation, autonomous vehicles.
 
Each segment faces different levels of US protectionist pressure and offers different opportunities for European companies.
 
 
Segment Analysis: Where the Barriers Are Highest
 
1. Foundation Models: The American Fortress
The clearest exclusion zone is foundation models - the GPT-4s and Claude-3s that require massive training investments. The US isn't just outspending competitors; it's building infrastructure designed to maintain permanent advantages.
 
Training costs for models like GPT-4 exceed $100 million, while OpenAI's recent $40 billion funding round demonstrates the scale of investment required. European companies aren't just facing funding gaps - they're competing against state-backed technological sovereignty.
 
However, specialised foundation models for European use cases remain viable. Germany's Teuken-7B, the EU's OpenEuroLLM project creating the first family of open-source LLMs covering all official EU languages, and Paris-based Bioptimus, which is developing universal AI foundation models for biology and medicine, demonstrate that European companies can build foundational infrastructure for markets American models systematically underserve.
 
2. AI Infrastructure: The Stargate Moat
The $500 billion Stargate Project makes clear that the US views AI infrastructure as a strategic asset. These aren't just data centres - they're specialised "AI factories" designed to maintain American platform dominance. A key component of this strategy involves co-locating AI facilities with dedicated energy generation capacity, creating self-sufficient computing complexes that can operate independently of traditional power grids.

This energy co-location strategy, discussed extensively at the AI summit, represents a fundamental shift toward AI infrastructure that combines computing power with direct energy generation - whether through nuclear, natural gas, or renewable sources - ensuring American AI facilities can scale without dependency on external power infrastructure.

European companies trying to compete at this layer aren't fighting for market share; they're challenging American technological hegemony.
 
3. Vertical Applications: The Regulatory Paradox
This is where European positioning becomes complex. While UK companies can still compete effectively in vertical applications across consumer, healthcare, financial services, and industrial sectors, applications built for European regulatory requirements (GDPR compliance, algorithmic transparency, bias detection) face active resistance in a US market that's explicitly rejecting what Trump calls "poisonous Marxism in technology."
 
At the Winning the AI Race summit, Trump announced he was "signing an order banning the federal government from procuring AI technology that has been infused with partisan bias or ideological agendas such as critical race theory." The message to European AI companies was clear: your regulatory compliance advantages in Europe become barriers to entry in America.
 
 
Where UK Companies Can Still Win: Three Strategic Priorities
 
Despite the protectionist headwinds, three hardware-focused segments offer genuine opportunities for UK and European DeepTech companies:
 
Priority 1: AI-Native Industrial Systems
The autonomous machines segment ($24.6 million average deal size, 5.7% of deals) represents the physical manifestation of AI where remote American competition is significantly hampered. When you're building robotic assembly systems for automotive manufacturing or AI-powered logistics automation, the intelligence must be embedded at the hardware level. This isn't software that can be cloud-delivered from Silicon Valley - it's industrial infrastructure that requires local presence, local expertise, and local trust.
 
UK companies like CMR Surgical (surgical robotics), Oxbotica (autonomous vehicle software), and Dogtooth Technologies (agricultural robotics) aren't building "AI applications" - they're creating AI-native physical systems that couldn't exist without intelligence built into the core architecture.

Priority 2: Specialised AI Semiconductors for Edge Computing
While general-purpose AI compute is dominated by NVIDIA, specialised semiconductors for edge AI, industrial IoT, and privacy-preserving computation remain accessible to European innovation. With $37.8 million average deal sizes, this market stays within European VC capacity while addressing use cases where relying on American cloud services creates unacceptable latency, privacy, or sovereignty constraints for local processing requirements.

Companies like UK-based Graphcore (AI processors), Netherlands-based Axelera AI (edge AI accelerators), and Israeli Hailo Technologies (edge AI chips) represent this approach - building specialised compute for specific AI workloads rather than competing with general-purpose dominance.
 
Priority 3: Regulatory-First Horizontal Platforms
Rather than avoiding European regulatory advantages, embrace them as technical capabilities. Build horizontal AI platforms - natural language processing, computer vision, AI automation - specifically designed for multi-jurisdictional compliance. As global corporations face increasingly divergent AI regulations between the US and Europe, there's growing demand for AI infrastructure that can navigate these differences technically, not just legally.
 
 
The Strategic Imperative: Build for Physical AI, Not Platform AI
 
The fundamental insight for UK founders is that European DeepTech's future lies not in competing with American AI software platforms, but in owning the intersection of AI and physical systems. While American companies build foundation models and cloud infrastructure, European companies can dominate the intelligent physical infrastructure that makes AI useful in the real world.
 
This means stopping thinking about "adding AI" to existing hardware and starting to design physical systems that are AI-native from the ground up. Industrial robotics that can't function without machine learning. Semiconductor architectures optimised for edge AI workloads. Manufacturing systems where intelligence is embedded at every layer.
 
The companies that succeed will be those that recognise AI integration isn't about software features - it's about reimagining what intelligent physical systems can do. That's not a platform challenge where American companies have structural advantages. It's an industrial challenge where European companies have decades of incumbency advantages in the sectors that matter most.
 
The fundamental message from Trump's address at the Winning the AI Race summit was uncompromising: "We mastered the Industrial Age, we created the Digital Age, and now we are leading the world into the golden age, indeed, the golden age of America. With your help, that golden age will be built by American workers. It will be powered by American energy. It will be run on American technology, improved by American artificial intelligence." This isn't just about market competition - it's about technological nationalism.

The US market may be closing for AI platforms, but it remains wide open for AI-native industrial solutions that can't be delivered remotely. With the UK's preferential 10% tariff advantage over the EU's 15% rate, British companies are particularly well-positioned to serve both European and American markets with hardware-embedded AI solutions.

For European DeepTech founders, the strategic imperative is clear: build for Physical AI, not Platform AI. The race isn't about copying American approaches anymore. It's about creating the intelligent infrastructure that AI software needs to touch the physical world.
