SoftBank Becomes Japan’s Largest Company After Market Value Tops ¥46 Trillion

SoftBank surpassed Toyota after its market value rose above ¥46 trillion, with investor enthusiasm tied to reported artificial intelligence infrastructure plans in France and a broader shift toward technology-led growth in Japan.

Fact Check
Nikkei Asia ('SoftBank dethrones Toyota as Japan's most valuable company') directly confirms SoftBank's market cap reached ¥46 trillion ($289B) on Monday and that it overtook Toyota as Japan's most valuable company. Cryptobriefing's two articles confirm the underlying catalyst: a pledge of up to €75 billion for AI data center capacity (5 GW) in France, described as Europe's largest AI infrastructure investment, announced May 30, 2026 at the Choose France summit. All three elements of the claim are corroborated.

Summary

SoftBank has overtaken Toyota as Japan’s largest company by market value, surpassing ¥46 trillion as investors rewarded its exposure to artificial intelligence and technology. Its shares have risen nearly 73% this year and more than 8% on Monday following reports that SoftBank pledged up to €75 billion for artificial intelligence computing clusters in France, with the project also described as Europe’s largest AI facility. The development is also being viewed as a sign of changing corporate leadership in Japan, where investors are increasingly favoring digital infrastructure and future-oriented technology over traditional manufacturing. Earlier reporting had cited a €45 billion investment in French AI data centers by 2031, while newer reporting points to a larger, more concentrated commitment, so both versions remain part of the record.
