SoftBank shares surge after Nvidia earnings beat

SoftBank Group rose more than 16% on May 21 after Nvidia’s latest results lifted sentiment around AI and underscored SoftBank’s exposure through Arm Holdings and OpenAI.

Arm, which majority owned by SoftBank, rose more than 15% in US trading, while hopes of a future OpenAI listing also helped drive the move.

Nvidia said revenue jumped 85% year on year to US$81.62 billion and announced a US$80 billion share buyback.

Analysts also said last week that Arm’s rally had strengthened SoftBank’s balance sheet despite heavy AI investment.

🧠 Food for thought

Implications, context, and why it matters.

SoftBank’s AI bets rely on new debt and Arm-backed borrowing

Investors cheer SoftBank’s AI ties through Arm Holdings and OpenAI, though the push relies on heavy borrowing.
SoftBank agreed to invest up to US$40 billion more in OpenAI and plans to syndicate US$10 billion, which leaves an expected net commitment of up to US$30 billion. That adds to US$2.2 billion from SoftBank Vision Fund 2, SoftBank’s second large technology investment fund, since September 2024 1.
The company is using its rising Arm Holdings stake as collateral to raise cash.
It is in talks for a US$5 billion margin loan, a loan backed by pledged shares. SoftBank earlier said it had raised its Arm-share-backed margin loan facility to US$20 billion 2.
The approach turns paper gains into cash for the AI push. It also ties Arm’s share price to SoftBank’s ability to fund future plans 3.

The market’s optimism hides a risky feedback loop

SoftBank’s stock climb has come with warnings about concentrated risk. Jefferies downgraded SoftBank Group over its focused holdings and growing financial commitments to OpenAI 4.
The company is also an OpenAI customer and pays about US$3 billion a year for services in Japan 4.
Money moving between an investor and its portfolio companies can lift valuations and blur each company’s financial position.
The pattern marks a shift from broader tech portfolios to debt-backed bets on a few AI companies. Wider market risk rises if OpenAI faces tougher competition 4.
