Kenji Tanaka stared at his computer screen in disbelief. As a supply chain manager for a major tech company, he’d seen shortages before, but this was different. The email from their Japanese supplier was brief but devastating: production delays on a critical material that most people had never heard of, but without which the entire AI revolution could grind to a halt.
“How can one company control so much of something so important?” he muttered to his colleague, not realizing he’d stumbled upon one of the tech industry’s best-kept secrets.
The answer lies in an unlikely place: Ajinomoto, the company you probably know for making MSG and other food additives, quietly controls 95% of the global supply of a material that’s absolutely essential for manufacturing AI chips like those powering Nvidia’s groundbreaking processors.
The Hidden Foundation of AI Technology
While everyone’s talking about ChatGPT, advanced AI models, and the chip wars between nations, there’s a critical piece of the puzzle hiding in plain sight. Ajinomoto Bio-Pharma Services, a subsidiary of the Japanese food giant, dominates the production of Ajinomoto Build-up Film (ABF), a specialized substrate material that serves as the foundation for high-performance semiconductors.
Think of ABF as the skeleton that holds everything together in modern AI chips. Without it, the complex, multi-layered processors that power artificial intelligence simply cannot exist. It’s not glamorous, it doesn’t make headlines, but it’s absolutely indispensable.
The semiconductor industry has become incredibly dependent on this single source, and most people outside the industry have no idea how vulnerable this makes our entire tech ecosystem.

This isn’t just about one company having a monopoly. It’s about how a food company accidentally became the gatekeeper of the AI revolution. Ajinomoto didn’t set out to control the future of artificial intelligence – they stumbled into it through decades of research into amino acids and biotechnology.
Breaking Down the Numbers: Japan’s Stranglehold on AI Infrastructure
The scale of this dominance is staggering. Here’s what the global ABF market looks like:
| Company | Market Share | Primary Use |
|---|---|---|
| Ajinomoto | 95% | High-end AI/GPU chips |
| Other suppliers | 5% | Lower-grade applications |
But the dependency goes even deeper. Here are the key facts that should worry anyone invested in the AI boom:
- Nearly every major AI chip manufacturer relies on Ajinomoto’s ABF substrates
- The production process takes months and requires specialized facilities
- Alternative materials exist but perform significantly worse for high-end applications
- Building new ABF production capacity takes 2-3 years minimum
- Ajinomoto’s main production facilities are concentrated in Japan and a few other Asian locations
The implications are mind-boggling. Every time you use ChatGPT, generate an AI image, or interact with any advanced AI system, there’s a 95% chance the underlying hardware depends on materials from this single Japanese company.
We’re essentially one natural disaster or geopolitical crisis away from a major disruption in AI chip production. That’s not a comfortable position for an industry worth hundreds of billions of dollars.

Why This Monopoly Happened (And Why It’s So Hard to Break)
You might wonder how a food company ended up controlling such a critical technology. The story goes back decades, to Ajinomoto’s research into amino acids and fermentation processes. Their expertise in creating precise, high-quality materials translated surprisingly well to semiconductor applications.
The company invested heavily in ABF technology when few others saw its potential. By the time AI chips became the hottest commodity in tech, Ajinomoto had already built an insurmountable lead in both technology and manufacturing capacity.
Breaking this monopoly isn’t just about money – it’s about time and expertise. ABF production requires:
- Proprietary chemical processes developed over decades
- Specialized manufacturing equipment
- Quality control systems that ensure near-perfect reliability
- Deep relationships with chip manufacturers
Even if competitors wanted to challenge Ajinomoto, they’d need years to develop comparable technology and build the necessary production infrastructure.
What This Means for the Future of AI
This hidden dependency creates ripple effects throughout the entire technology ecosystem. When Ajinomoto faces production challenges, AI chip manufacturers feel the impact immediately. When geopolitical tensions rise between Japan and other nations, the entire AI industry holds its breath.
For consumers and businesses relying on AI technology, this concentration of power in one company creates several concerning scenarios:
- Supply shortages could dramatically increase AI chip prices
- Production delays could slow the rollout of new AI technologies
- Natural disasters in Japan could disrupt global AI development
- Trade disputes could weaponize this critical supply chain
The AI revolution everyone’s excited about is built on a surprisingly fragile foundation. We need more companies capable of producing these critical materials, or we’re setting ourselves up for major problems down the road.
— Dr. Jennifer Liu, Materials Science Researcher
Major tech companies are starting to wake up to this reality. Some are investing in alternative suppliers or developing new substrate technologies. Others are building closer relationships with Ajinomoto to ensure continued access to ABF materials.
The race is on to diversify this critical supply chain before a crisis hits. But with Ajinomoto’s decades-long head start and the complexity of ABF production, breaking their monopoly won’t happen overnight.
Smart companies are already working on contingency plans, but the reality is that Ajinomoto will likely maintain this dominant position for years to come. The question is whether the industry can build enough alternatives to reduce the risk.
— Robert Kim, Semiconductor Industry Consultant
For now, the future of artificial intelligence – from the chatbots on your phone to the autonomous vehicles of tomorrow – depends on a Japanese food company that most people have never heard of. It’s a reminder that in our interconnected world, the most critical dependencies often hide in the most unexpected places.
FAQs
What exactly is ABF and why is it so important for AI chips?
ABF (Ajinomoto Build-up Film) is a specialized substrate material that provides the foundation for high-performance semiconductors, allowing multiple layers of circuits to be built in modern AI processors.
Could other companies start making ABF to compete with Ajinomoto?
Yes, but it would take 2-3 years minimum to build production capacity and develop the necessary expertise, making it a long-term solution rather than a quick fix.
What happens if Ajinomoto’s production gets disrupted?
Any major disruption could slow AI chip production globally, potentially increasing prices and delaying new AI technology releases across the industry.
Are tech companies aware of this dependency?
Major players in the AI industry are increasingly aware and some are investing in alternative suppliers, but the transition away from this dependency will take years.
How did a food company end up controlling AI chip materials?
Ajinomoto’s expertise in amino acids and precision chemical processes translated well to semiconductor materials, and they invested early in ABF technology before its importance became clear.
Is this monopoly legal?
Yes, Ajinomoto earned their market position through innovation and investment, though regulators in various countries are monitoring the situation due to its strategic importance.
