SoftBank pays off its OpenAI bridge loan early, takes a ¥321.9 billion derivative hit

SoftBank Group has cleared the bridge loan it took out to fund its massive bet on OpenAI, months before the money was due back.

The catch is the price. One of the tools it used to raise cash, a prepaid forward tied to its Intel shares, left the company with a ¥321.9 billion derivative loss after Intel’s stock climbed.

How SoftBank refinanced the bridge

The original facility was a $40 billion unsecured bridge loan arranged in March 2026. It was set to mature in March 2027.

Major banks led the deal, including JPMorgan Chase and Goldman Sachs. Its main purpose was financing a $30 billion follow-on investment in OpenAI through SoftBank’s Vision Fund 2.

By mid-September 2026, SoftBank said it had repaid the drawn portion of the loan in full. It also canceled the capacity it never tapped.

The money came from several places at once:

• A term loan of $11.87 billion.
• Intel-backed prepaid forward contracts that raised approximately $7.35 billion in August 2026. The arrangement included a share collar on SoftBank’s Intel stake.
• A larger Arm-backed margin loan. The facility was upsized by $5 billion to $25 billion in September 2026, secured by SoftBank’s large stake in Arm.
• Bond proceeds, which rounded out the package.

The Intel trade that cost ¥321.9 billion

In a prepaid forward, an investor receives cash upfront in exchange for delivering shares, or their cash value, at a future date. A collar sets a floor and a ceiling on the price range the investor is exposed to.

That structure protects against a falling stock. It also caps the upside. When Intel shares rose, the value of SoftBank’s obligation under the contracts moved against it, producing the ¥321.9 billion derivative loss.

The loss reflects accounting for the contract’s fair value rather than a fire sale of assets.

The OpenAI bet keeps growing

After an additional $10 billion tranche in October 2026, SoftBank’s cumulative investment in OpenAI reached $64.6 billion. That works out to a stake of about 13%.

A smaller balance sheet cushion

As of September 30, 2026, the group reported a net asset value of ¥59.8 trillion, or $380 billion. That was down from ¥72.3 trillion on June 30.

Cash stood at ¥5.0 trillion, or $32 billion.

What this means for SoftBank and its lenders

The early payoff removes a looming 2027 deadline. The trade-off is where the risk now sits. Much of the replacement funding is tied to the value of specific stocks, namely Arm and Intel.

An Arm-backed margin loan is fine while Arm shares hold up. If they fall sharply, margin loans can require more collateral or repayment, and a $25 billion facility makes that exposure meaningful.

The Intel structure carries the opposite issue. SoftBank has already shown it gave up upside when Intel rose, and the ¥321.9 billion loss is the visible result.

With $64.6 billion committed and about 13% ownership, SoftBank’s fortunes are increasingly linked to how the market ultimately values OpenAI, a private company whose valuation is set in funding rounds rather than on a public exchange.
