SoftBank Bets the House on “Artificial Super Intelligence” – CEO Masayoshi Son

SoftBank founder Masayoshi Son has never been shy about moon-shot pronouncements, but his latest pledge pushes even past the WeWork era: he told shareholders he wants SoftBank to become “the world’s leading Artificial Super Intelligence platform within ten years” and is ready to pour breath-taking sums into that quest. The centrepiece of the plan is an additional $40 billion underwriting commitment for OpenAI, on top of the billions SoftBank has already channelled into the ChatGPT maker, and a just-completed $6.5 billion cash acquisition of chip-designer Ampere Computing. Shares in Tokyo and Hong Kong jumped to record highs as Son declared, “Everything we’ve done so far was warm-up. Now the real game begins.”

The timing is exquisite. After four straight loss-making years, SoftBank’s Vision Fund is finally back in the black, buoyed by Arm’s soaring royalty revenue and a string of AI-related exits. Son is using that tail-wind to re-fuel his trademark “go-big or go-home” strategy. Analysts tally SoftBank’s total exposure to OpenAI at about $32 billion already, rising toward $40 billion as new equity and convertible notes close. If the AI lab ever lists, SoftBank would be its single largest outside shareholder, effectively making the Japanese conglomerate the financial backbone of Silicon Valley’s most talked-about company. 

But hardware is the other half of Son’s ASI equation. Arm still sits at the heart of 99 percent of the world’s smartphones, yet cloud data centres hungry for AI workloads have been shifting toward Nvidia and AMD. Buying Ampere Computing—designer of high-core-count Arm server CPUs used by Google and Microsoft—gives SoftBank a direct stake in that compute boom and an instant channel for pairing OpenAI-class models with Arm-optimized silicon. Son hinted that fresh joint ventures could link Ampere, Arm and OpenAI into a vertically-coherent “ASI stack” that SoftBank could license to every major cloud provider. 

For observers in the United States and the United Kingdom, the numbers redefine what post-dot-com risk tolerance looks like. Few Western boards would authorise a single-company bet of $40 billion—especially on a partner with lightly tested commercial revenues—but Son argues that Artificial Super Intelligence (ASI) will dwarf the internet and smartphone booms combined. In Germany and Norway, where Arm-based datacentres are ramping to support green-energy analytics and next-gen telecom, Ampere’s new SoftBank backing could accelerate local deployments. Nigerian tech circles, meanwhile, see a different upside: if OpenAI’s enterprise tools trickle down at SoftBank-subsidized rates, Lagos start-ups could leapfrog access barriers that once kept advanced AI firmly in Silicon-Valley hands.

Sceptics will recall that Son’s last era of exuberance birthed both the Alibaba jackpot and the WeWork fiasco. They point out that OpenAI’s valuation, reportedly above $300 billion, leaves scant margin for error if the commoditisation curve for large-language models steepens. There’s also execution risk: integrating Ampere, coaxing OpenAI toward an IPO, and keeping Arm’s newfound market cap intact is a plate-spinning act few corporations could manage even with calmer personalities at the helm.

Yet markets seem to believe this is Son’s arena. SoftBank stock has gained more than 60 percent year-to-date, hitting a 24-year high, and Vision Fund portfolio companies—from autonomous-driving firm Cruise to UK fintech Revolut—have quietly advanced toward exits that may pump even more dry powder into the ASI war-chest. For Son, the endgame is clear: own the chips, the models and the capital pipeline that fuels them, then sell that integrated package to every enterprise scrambling for an AI edge.

Whether the world buys SoftBank’s grand unification pitch is still uncertain, but the stakes are undeniable. If Son is right, SoftBank could sit at the control panel of intelligence engines that are—by his count—10,000 times smarter than any human. If he’s wrong, the Vision Fund could face another WeWork-scale write-down, only this time multiplied by the size of the frontier it’s chasing. Either way, SoftBank has pushed the AI race into a new, ultra-expensive gear, and the rest of the tech world—from Silicon Valley to Shenzhen—will now have to decide whether to chase, partner or get out of the way.
