Driving SoftBank's debt-financed expansion of its OpenAI stake

SoftBank Group cut its target for a margin loan backed by OpenAI shares from $10 billion to as low as $6 billion after lenders pushed back, Bloomberg reported May 8. The reduction came days after the Wall Street Journal reported that OpenAI had missed internal revenue and user-growth targets in early 2026. Anthropic had gained share in coding and enterprise markets. Lenders said the difficulty of pricing a private company with slowing growth made them unwilling to commit at the original size.

Controls roughly 90% of Arm; primary financial beneficiary of the pivot

For 35 years, Arm Holdings sold blueprints, not chips. Apple, Qualcomm, Nvidia and Amazon paid Arm to license its processor designs, then made the silicon themselves. On May 6, 2026, Arm formalized a different future: a $15 billion direct chip-sales business by fiscal 2031, anchored by an in-house data center processor called the Arm AGI CPU. Customer demand for the chip has already doubled to more than $2 billion for fiscal years 2027–2028 since the March 24 launch, and an IBM collaboration announced in April extended the AGI CPU's reach toward enterprise mainframes.

Delivered second $10B tranche from $40B loan, completing $40B total OpenAI commitment in $122B round

OpenAI closed a record $122 billion funding round on April 1, 2026, lifting the maker of ChatGPT to an $852 billion post-money valuation and eclipsing every prior private capital raise. Amazon led with a $50 billion commitment -- $15 billion upfront and $35 billion contingent on OpenAI reaching artificial general intelligence or completing an IPO by year-end. Nvidia and SoftBank each committed $30 billion, with SoftBank's second $10 billion tranche arriving alongside closes from a16z and D.E. Shaw. The round took the company from a $157 billion valuation seventeen months earlier to one more than five times larger.

Largest single investor in OpenAI with over $70 billion committed

Four months ago, Sam Altman told the world OpenAI had $1.4 trillion in data center commitments. Now the company is telling investors the real number is $600 billion — and that it would rather rent computing power than build its own facilities. The retreat, disclosed to investors in February 2026 and detailed publicly on March 22, marks the sharpest pivot in the short history of the artificial intelligence spending boom.

Leading SoftBank's pivot to AI infrastructure ownership while racing to meet $22.5B year-end Stargate funding deadline

SoftBank just agreed to pay $4 billion for DigitalBridge, the alternative asset manager that controls $108 billion in data centers, cell towers, and fiber networks across three continents. It's the latest—and clearest—signal that Masayoshi Son is betting SoftBank's future on owning the physical infrastructure that powers AI, not just the software running on top of it. The timing is no coincidence: SoftBank is racing to secure $22.5 billion by year-end 2025 to meet its Stargate funding commitment to OpenAI.
