- • Founder Masayoshi Son expressed high confidence in OpenAI's prospects and future public listing potential, characterizing the ongoing AI revolution as potentially "50x bigger than the dot-com boom."
- • SoftBank announced a €75 billion ($87 billion) investment plan for AI infrastructure development in France, including 5 gigawatts of data center capacity, marking its largest European AI commitment to date.
- • Arm Holdings remains SoftBank's largest portfolio holding at over 50% of net asset value, while the company has doubled down on AI infrastructure bets across multiple geographies through partnerships including the Stargate project with OpenAI.
Summary
Son disclosed that OpenAI represents just over 20% of SoftBank's net asset value, positioning it as a significant but not dominant position within the conglomerate's portfolio. Arm Holdings maintains the group's largest allocation at over 50% of net asset value, providing substantial diversification relative to the OpenAI bet. The founder's confidence in OpenAI's trajectory comes as the AI company reportedly explores a future public listing, a development that could materially impact SoftBank's stake valuation.
The investment conviction extends beyond equity stakes. SoftBank earlier this year partnered with OpenAI on the Stargate project, a joint venture focused on developing critical AI infrastructure in the United States. Concurrently, the company announced a €75 billion ($87 billion) infrastructure investment plan for France, encompassing the construction of 5 gigawatts of AI data center capacity—the company's largest European AI infrastructure commitment to date. This multi-geography approach underscores Son's thesis that AI infrastructure will drive substantial value creation globally.
Son's broader market perspective frames the current AI cycle as transformative relative to historical technology booms. He stated that the ongoing AI revolution could be "more than 10x, probably 50x bigger than the dot-com" bubble of the 1990s and 2000s, drawing on historical precedent to support boom-and-bust cycles as inherent features of innovation systems. These comments position SoftBank's capital allocation decisions as long-term bets on AI infrastructure maturation, justified by the perceived scale of the opportunity relative to prior technological transitions.
SoftBank's strategy culminated in the company surpassing Toyota to become Japan's most valuable corporation for the first time in 20 years, a milestone that reflects investor recognition of its AI-focused portfolio transformation and infrastructure investment thesis.
