Rapidus’s $15 Billion Chip Bet Hinges on Winning Customers
Japan has put $15 billion of state backing behind Rapidus, and the project now faces one question that matters more than any other: can it fill its factory? The chipmaker said on Monday that it is partnering with 17 companies, including US chip design software firm Synopsys and India’s Infosys, to help customers design chips. The move is a step forward, but analysts say it is not yet proof that customers are lining up.
Key Takeaways
- The bet: Rapidus has $15 billion in state backing to build a leading-edge chip factory in Japan
- The news: On Monday, it announced partnerships with 17 companies, including Synopsys and Infosys
- The deadline: 2-nanometre contract chip production is planned for the second half of the next fiscal year
- The risk: Securing enough customers, plus technology and competition hurdles
- The long game: An IPO is targeted around the financial year ending March 2032
Why Does Rapidus Need Customers So Urgently?
Rapidus has to secure customers before it launches 2-nanometre contract chip production, which is planned for the second half of the next fiscal year. Prime Minister Sanae Takaichi is counting on the project to help rebuild Japan’s semiconductor industry.
Nori Chiou, investment director at White Oak Capital, put the issue plainly: the biggest open question is still who will actually fill the fab. In his view, Monday’s announcement is not yet evidence of commercial traction, though it does show incremental progress.
What Is at Stake for Japan?
Failure would be a major setback for Japan’s industrial strategy and could ripple across the country’s chip sector. Tokyo is trying to strengthen supply chain resilience at a time of rising regional tensions and concern about a possible Chinese move against Taiwan.
The context is long. Japan’s share of the global semiconductor market has fallen from about 50% in the 1980s to less than 10% today. Chipmakers operating in Japan include memory producer Kioxia and TSMC, which has partnered with Sony. Another government-backed effort, Noetra, is developing a foundational model for physical AI and robotics.
Who Is Rapidus Up Against?
Rapidus aims to make 2-nm chips, which deliver faster and more energy-efficient performance than earlier generations. The AI investment boom has pushed up demand for semiconductors and computing infrastructure, and Rapidus hopes to benefit.
But the competition is heavyweight:
- TSMC (Taiwan): Spent decades refining its processes and dominates leading-edge chipmaking
- Samsung Electronics (South Korea): Began producing 2-nm chips last year
- Intel (US): Also competes at the leading edge
Akira Minamikawa, an analyst at Omdia, expects TSMC to keep the majority of the market. However, he says plenty of customers in the remaining 20% cannot get capacity from TSMC, either because they are low on its priority list or because their orders are small. That is the gap Rapidus is aiming for.
Is There Enough Demand for Another Leading-Edge Chipmaker?
Rapidus CEO Atsuyoshi Koike is confident there is. He told Reuters that one or two companies are nowhere near enough to meet demand.
Some potential customers are more careful. One executive, who asked not to be named because the discussions are private, said his company already has TSMC making its chips and cannot move everything to Rapidus. If Rapidus did not deliver, he said, there would be no easy way back to TSMC, so caution is needed.
Minamikawa sees two possible upsides. Customers may use Rapidus to diversify their supply chains, and the presence of a leading-edge manufacturer in Japan could also benefit the country’s materials and equipment makers.
What Technology Hurdles Remain?
Koike said preparations for mass production are on schedule and that the environment is better than the company expected when it was founded in 2022. Rapidus is working with IBM and has started pilot operations.
Even so, experts say commercial success is far from guaranteed. Kazuyoshi Saito, an analyst at IwaiCosmo Securities, noted that running a fab around the clock, keeping yields stable and sustaining a viable business is extremely difficult. He pointed out that even Samsung has struggled.
What Does the Longer-Term Picture Look Like?
Beyond proving its technology, Rapidus has to build a profitable business. It is targeting an initial public offering around the financial year ending March 2032.
A government official was blunt about the horizon. Success or failure will not be clear for about 10 years, the official said, and no one will be able to take responsibility. The official pointed to the government-backed Cool Japan Fund, which booked investment losses, as a cautionary example.
Rapidus’s backers still have big plans. Daishiro Yamagiwa, a lawmaker who heads the ruling Liberal Democratic Party’s parliamentary group on chip strategy, said a listing and manufacturing operations in the United States are both possibilities.
