Japan plans to invest up to $21 billion in two chip factories in the United States, and GlobalFoundries will run them, according to a Nikkei Asia report. The figure is the largest single overseas manufacturing commitment attributed to Tokyo in the current cycle of semiconductor subsidies.

The deal, as reported by Nikkei, would place Japanese capital behind US-based fabrication capacity operated by GlobalFoundries, the Malta, New York-based foundry that exited leading-edge logic development years ago and now sells mature and specialty process nodes to automotive, industrial, and communications customers.

What do we know so far?

The confirmed facts are narrow. Nikkei reports:

• An investment of up to $21 billion from Japan.
• Two factories located in the United States.
• GlobalFoundries as the operating company.

The report has not specified process nodes, wafer sizes, site locations, construction timelines, or how the Japanese contribution would be structured. Whether the funds flow as direct government investment, through a joint venture, or via Japanese corporate partners remains unstated.

Tokyo has not confirmed the plan publicly. GlobalFoundries has issued no statement beyond the report. Treat site selection, capacity targets, and any revenue projections as roadmaps until the parties announce them.

Why would Japan fund US capacity?

The reported plan fits a broader pattern. Japan has spent heavily to rebuild domestic chip manufacturing, including support for Kioxia's memory plants and for Rapidus, the venture targeting 2-nanometer logic production in Hokkaido by 2027.

An investment in US factories would extend that strategy beyond Japanese soil. It would also align Tokyo with Washington's push to onshore advanced and mature chip production, a push funded by the CHIPS and Science Act's $52.7 billion allocation. Japan and the United States have cooperated on semiconductor supply chains since 2022, when both governments joined a framework that also includes South Korea and Taiwan.

For Japan, US-based capacity offers a hedge. It secures access to fabrication outside East Asia at a time when geopolitical risk around Taiwan, home to TSMC's most advanced plants, dominates supply chain planning for every major chip buyer.

What does the deal mean for GlobalFoundries?

GlobalFortries' foundry, GlobalFoundries, reported full-year 2024 revenue of $6.75 billion. Its existing network spans fabs in Malta, New York; Burlington, Vermont; Dresden, Germany; and Singapore.

Two additional US plants, funded by Japanese capital, would materially expand that footprint. GlobalFoundries already received $1.5 billion in planned direct CHIPS Act funding for its Malta and Vermont sites, announced in February 2024. The Nikkei-reported Japanese investment would run well beyond that amount and would make Japan a second government backer of the company's capacity buildout.

The foundry specializes in nodes from 12nm upward, including 22FDX FD-SOI, silicon photonics, and gallium nitride processes. Any new plants would most plausibly target these specialty markets rather than leading-edge logic, though no process detail appears in the report.

Who benefits from the extra capacity?

Mature-node capacity remains in demand from automakers and industrial equipment makers. Those customers endured severe shortages in 2021 and 2022 and have since pushed suppliers to guarantee long-term supply.

Japanese capital entering US fabs would connect two of the three largest pools of automotive chip demand and supply-chain investment. It would also add non-Taiwanese, non-Chinese capacity at a moment when Washington restricts advanced tool exports to China and Beijing retaliates with its own controls on gallium and graphite exports.

What comes next?

The $21 billion figure and the two-factory structure come from a single report. Investors and supply chain planners should watch for a formal announcement from GlobalFoundries, Japan's Ministry of Economy, Trade and Industry, or the US Commerce Department.

If confirmed, the deal would mark the largest Japanese semiconductor investment in US manufacturing to date and would intensify competition in specialty foundry capacity against TSMC's Arizona complex and Samsung's Taylor, Texas plant, both of which are scaling toward volume production in 2025.
