SoftBank Shares Jump 16% After Nvidia AI Earnings
SoftBank Group shares surged more than 16% after Nvidia reported blockbuster quarterly results that signalled strong momentum in artificial intelligence. The rally reflected SoftBank’s exposure to the AI boom through its stake in Arm Holdings (whose chip designs are widely used in AI servers) and its large investment in OpenAI. SoftBank has invested over $30 billion in OpenAI and reported investment gains of about $45 billion in the year ended March. Nvidia reported revenue up 85% year-over-year to $81.62 billion, unveiled an $80 billion share repurchase program and raised its dividend. Market commentators and analysts (including Andrew Jackson of Ortus Advisors and CreditSights at Fitch) said Nvidia’s results materially strengthened optimism around AI-related assets and a potential OpenAI listing.
Nvidia’s blockbuster earnings and large buyback signal accelerating demand for AI infrastructure, which materially affects valuations of AI‑exposed companies (SoftBank, Arm) and investment flows across the tech sector.

SoftBank shares jump over 7% after $11.1B bond issuance to fund OpenAI investment
SoftBank Group shares surged over 7% on Thursday as Japanese markets reopened after a holiday, following the company's announcement of an $11.1 billion bond issuance. SoftBank issued $10 billion in dollar-denominated senior notes and €1 billion in euro-denominated notes. Proceeds will fund the final $10 billion tranche of its $30 billion follow-on investment in OpenAI, expected to close on October 1, 2026, and for general corporate purposes. This brings SoftBank's cumulative investment in OpenAI to $64.6 billion, giving it an approximately 13% stake. The move underscores CEO Masayoshi Son's aggressive push into AI and comes amid investor scrutiny over SoftBank's rising leverage and ability to finance its AI ambitions.
SoftBank Rakes in $4.2 Billion from OpenAI Investment
SoftBank Group reported a fiscal third-quarter net profit of ¥248.6 billion ($1.6 billion), driven in part by a ¥4.2 billion gain on the value of its OpenAI investment and a ¥2.4 billion gain at its Vision Fund in the December quarter. SoftBank said it has invested more than $30 billion in OpenAI and owns approximately 11% of the company, recording about $17 billion of gains on that stake from April to December. The company flagged markdowns and share-price declines in other holdings — including Coupang, Didi and ByteDance — and said it has been selling assets (Nvidia, T-Mobile stakes) and using loans backed by holdings to fund AI investments. SoftBank also created a new "AI Computing Segment" that groups chip assets such as Arm, Graphcore and Ampere; that segment posted a ¥91.8 billion loss over the nine months to December.
