SoftBank Group has overtaken Toyota Motor Corp. to become Japan’s most valuable listed company, driven by strong investor optimism surrounding artificial intelligence and the company’s growing role in the global AI ecosystem.
The milestone comes after a sharp rally in SoftBank shares, which have surged on expectations that the company will be a major beneficiary of the AI boom. Investors have increasingly focused on SoftBank’s extensive investments in artificial intelligence, semiconductor technology and data infrastructure, helping push its market capitalisation above that of Toyota, long regarded as Japan’s corporate heavyweight.
At the centre of investor enthusiasm is SoftBank founder and CEO Masayoshi Son’s renewed focus on AI. Son has repeatedly described artificial intelligence as the most significant technological shift of the century and has positioned SoftBank to capitalise on the trend through investments in chip design, AI infrastructure and next-generation computing technologies.
One of the key drivers behind the company’s rising valuation is its stake in British chip designer Arm Holdings. Since Arm’s successful public listing, its market value has climbed significantly as demand for AI-related semiconductor technology has accelerated worldwide. Arm’s processor designs are widely used across smartphones, data centres and emerging AI applications.
SoftBank has also announced ambitious plans to expand its presence in AI infrastructure. The group is investing in data centres, advanced computing facilities and partnerships aimed at supporting the growing demand for artificial intelligence services. Investors view these initiatives as positioning the company at the heart of the AI supply chain.
The development marks a significant turnaround for SoftBank, which faced challenges in recent years due to losses at its Vision Fund investment unit and declining valuations among several technology startups. The resurgence of AI-related investments has helped restore market confidence in the conglomerate’s long-term strategy.
Toyota remains one of the world’s largest automakers and continues to command strong investor support, but market attention has increasingly shifted toward companies linked to artificial intelligence and advanced technology.
