SoftBank's OpenAI Stake Faces a Reset as Funding Ambitions Cool

SoftBank Group investors spent much of the past week weighing two competing narratives: a resurgent AI trade that lifted the stock, and a quieter but potentially more consequential shift in how its most important bet plans to raise money.

Reports that OpenAI has scaled back the ambitions of its current funding round weighed on the Japanese conglomerate at the open, according to Nikkei, though the shares clawed back much of that ground as the session wore on. The episode put a spotlight on the terms under which OpenAI will secure fresh capital — and what those terms mean for a stake SoftBank has already built at considerable expense.

A Smaller Ask, a Lower Ceiling

OpenAI has cut the target for its ongoing raise from USD 30 billion to USD 20 billion, the Financial Times reported. The Wall Street Journal put commitments at roughly USD 11 billion — a figure that reflects investor interest rather than a closed round.

The distinction matters. A target is a wish; a signed round is a fact, and how much OpenAI ultimately collects has yet to be settled. Reuters reported that the first close of the round is likely to land below the USD 20 billion mark.

Alongside the smaller ask, the company trimmed its hoped-for valuation from USD 1.4 trillion to USD 1.25 trillion, according to the FT. Some backers, the newspaper added, want to see Anthropic's market pricing first — making a rival's valuation the yardstick for OpenAI's own fundraising. That complicates any reading of the commitments disclosed so far: they demonstrate appetite, but leave the final terms unresolved.

What It Means for a 13% Holder

SoftBank said on October 1 that it had completed the final tranche of its previously pledged additional investment in OpenAI, bringing its cumulative outlay to USD 64.6 billion and its holding to about 13%.

A lower target valuation for new money is not the same as a realized loss on that position. It is, for now, a negotiating parameter of a round still in progress, and any firm judgment must wait on the final valuation and closing conditions.

The stock's recovery from its weak start did little to dispel that uncertainty. The real test remains the completion of the funding round, when the reduced targets can be measured against terms actually agreed. Until then, investors would do well to keep media reports of commitments, aspirational valuations and completed investments in separate mental buckets.

A Rally, and the Debt Beneath It

The funding headlines landed against a brighter backdrop. An AI-driven rally on Wall Street on October 27 sent SoftBank shares up 7%, with the upswing reported to have spread across Asian technology names. Coverage also flagged concerns about borrowing costs for data centers and the purchase of AI chips.

Debt tied to SoftBank's AI investments and doubts about their profitability had already been cited in media reports on October 22 as a drag, alongside worries about rising credit risk. Premiums on credit default insurance reached their highest level in nearly four years on October 20, according to that reporting.

On one existing obligation, SoftBank could point to a completed step: it confirmed on October 23 the early repayment of its 2021 euro-denominated senior notes. The bonds were redeemed in full and cancelled, leaving nothing outstanding from that issue. They carried a 2.875% coupon and would have matured on January 6, 2027.

A Framework, Not a Commitment

Beyond the financing questions, a possible infrastructure project in Malaysia is on the table. SoftBank signed a framework agreement on October 8 with Grab Holdings and Petroleum Sarawak Berhad to explore a platform for artificial intelligence and digital infrastructure in Sarawak.

By the companies' own account, the arrangement obliges none of them to sign final contracts or to carry the project through.

One concrete payout, however, is locked in. About two weeks ago the board set an interim dividend of JPY 5.50 per share, totaling JPY 31,346 million, payable on December 2, 2026, with September 30 as the record date.

SoftBank publishes quarterly results on November 10 — the next scheduled checkpoint for assessing how its holdings are developing and where the group's finances stand.
