SoftBank Q1 Profit Drops 17.7% as Its OpenAI Bet Nears a 13% Stake

SoftBank’s Q1: Revenue Grows as OpenAI Commitment Deepens

SoftBank Group posted a net profit of ¥347.33 billion (€1.91 billion) for its fiscal first quarter ended June, a 17.7% decline from the same period a year earlier. Revenue, however, climbed 10.9% to ¥2.02 trillion (€11.1 billion), signalling that while operating momentum continued, bottom-line growth was dented by year-earlier comparison effects and the cost of its vast investment portfolio.

The Japanese conglomerate, led by founder Masayoshi Son, spotlighted its ballooning stake in OpenAI. By the end of the quarter, cumulative investment in the artificial intelligence company hit $44.6 billion (€38.6 billion), with a fair value of $89.6 billion (€77.6 billion) and an unrealised gain of $45 billion (€38.98 billion). SoftBank confirmed it had already completed two of three planned additional tranches—$10 billion in April and another $10 billion in July 2026—as part of a further $30 billion commitment announced in February. After a final $10 billion payment expected in October 2026, total investment will reach $64.6 billion (€55.95 billion), giving SoftBank an ownership interest of about 13%.

Elsewhere, the group recorded investment gains of ¥1.86 trillion (€10.22 billion), a 287% jump from the prior-year quarter. The bulk came from a latent gain of ¥1.33 trillion (€7.31 billion) on its Intel position, alongside revaluations of the ByteDance holding. The two tech-focused Vision Funds contributed a profit of ¥460.1 billion (€2.53 billion), down 30.3% year-on-year, largely because of a ¥358.4 billion (€1.97 billion) fair-value increase on ByteDance that was smaller than a year earlier.

Where SoftBank’s Multibillion-Dollar Bets Are Paying Off—and Where the Risks Lie

Scratching beneath the headline profit dip, SoftBank’s quarter was defined by the widening valuation gap between its marquee AI bet and its more traditional technology holdings—and by the sheer scale of the OpenAI gamble that is rapidly becoming the central pillar of Son’s investment thesis.

The OpenAI Calculus: A 13% Stake at an Implied $500 Billion Valuation

The numbers tell the story: a cumulative $64.6 billion investment for a 13% ownership implies an enterprise value for OpenAI of roughly $500 billion. That is a startling figure for a company that remains largely pre-revenue in the conventional sense, yet it mirrors the market’s conviction that artificial general intelligence (AGI) will eventually command platform-level economics. SoftBank is effectively betting that OpenAI’s technology, distribution and licensing potential will justify a valuation multiples of today’s leading cloud platforms within a decade. The two tranches already deployed in April and July suggest the group is moving fast, and the final October payment will cement its status as the largest external shareholder by some margin.

Intel and ByteDance: The Rocket Fuel That Lifted Quarterly Gains

While OpenAI dominates the narrative, the quarter’s gain surge was powered by legacy bets. A latent gain of ¥1.33 trillion on Intel stock—whether from a direct stake or derivatives—dwarfed all other contributors. Combined with a revaluation of ByteDance inside the Vision Funds, these positions delivered the bulk of the ¥1.86 trillion in reported investment gains. The message is that SoftBank’s earlier, riskier wagers in semiconductors and social media are finally crystallising value, providing a financial buffer that allows Son to keep writing enormous cheques for AI. The Vision Funds’ profit decline, on the other hand, was a matter of timing: ByteDance’s valuation had already jumped sharply in the prior year, so the incremental uplift was simply smaller this time around.

What the Earnings Mix Says About SoftBank’s Transformation

The revenue rise, driven by the holding company’s operating subsidiaries and income from its investment portfolio, shows the engine is turning. But net profit fell because the first quarter of the previous fiscal year likely included larger one-off disposals or exceptional items that were not repeated. SoftBank is, in effect, swapping short-term profit consistency for long-term exposure to a sector—artificial intelligence—where revenue models are still forming. This quarter’s results confirm that the Vision Funds are no longer the sole growth driver; the OpenAI commitment has changed the company’s centre of gravity from a diversified tech fund to a concentrated AI-first vehicle.

What SoftBank’s Corporate Showcase Means for Investors and the Tech Sector

• Monitor the October 2026 tranche and implied valuation. After SoftBank deploys the final $10 billion, its $64.6 billion investment will give it a 13% stake—implying an OpenAI valuation near $500 billion. Any delay or renegotiation of that payment would signal shifting sentiment. The next milestone is whether OpenAI’s revenue or product launches can justify that number in the public or private markets.
• Watch for exits from Intel and ByteDance positions. The $1.86 trillion in gains are largely unrealised. If SoftBank begins to monetise the Intel stake or the Vision Funds sell down ByteDance, it would unlock cash that could either be returned to shareholders or channelled into additional AI bets—a pivotal strategic signal.
• Expect further concentration in AI. With SoftBank’s cumulative investment in OpenAI set to exceed $64 billion, the group’s balance sheet is becoming disproportionately exposed to a single private company. Investors should stress-test scenarios where OpenAI’s commercial rollout disappoints, given that SoftBank’s mark-to-model gains could reverse sharply.
• Competitors in chip design and AI platforms face a powerful backer. SoftBank’s massive OpenAI position, combined with its Intel exposure, gives it leverage across the AI stack. Rivals such as Google, Meta, and emerging AI labs will watch whether SoftBank uses its influence to steer technology standards or partnership choices in OpenAI’s favour.
