• SoftBank's cumulative investment in OpenAI has reached $64.6 billion, giving it roughly 13% ownership, but the massive bet faces mounting scrutiny.
  • OpenAI reportedly scaled back its latest fundraising target to ~$20 billion from $30 billion, and its valuation to $1.25 trillion from $1.4 trillion.
  • SoftBank shares fell 10.8% on November 6, and its credit-default swaps hit their highest level since 2022 as investors question AI returns.

SoftBank Group (TSE:9984)'s massive wager on OpenAI has ballooned to $64.6 billion, the Japanese conglomerate disclosed in October, marking a dramatic escalation from the "hundreds of millions" initially discussed in 2024. The investment now gives SoftBank roughly 13% ownership of the AI pioneer, but the sheer scale has raised questions about concentration risk and the path to profitability.

The final $10 billion installment of SoftBank's $30 billion follow-on commitment was completed on October 1, financed through foreign-currency senior notes. The company said its earlier $40 billion bridge facility had been fully repaid and remaining undrawn commitments canceled. Still, the move replaces temporary financing; it doesn't eliminate the debt underpinning SoftBank's investment strategy.

A Funding Round in Flux

OpenAI's latest fundraising effort, in which SoftBank was expected to participate, remains unsettled. A November 2 report citing the Financial Times said OpenAI had reduced its target from $30 billion to approximately $20 billion and cut its anticipated valuation to $1.25 trillion from $1.4 trillion. Those are reported targets, not confirmed closing terms, and OpenAI has not publicly commented.

Revenue growth has not quelled concerns about costs. Reuters (NASDAQ:TRI) reported that OpenAI's September 2026 annualized revenue was almost $50 billion, below an earlier indication approaching $70 billion. Annualized revenue extrapolates a recent operating pace; it's not revenue already earned over a full year. In April, Reuters relayed Wall Street Journal (NASDAQ:NWSA) reporting that OpenAI had missed user and revenue goals, and that CFO Sarah Friar had raised concerns about paying for future computing commitments if revenue growth disappointed.

Market Jitters

Investors are increasingly questioning the timing and profitability of AI investments. SoftBank shares closed down 10.8% on November 6, according to Reuters, while its five-year credit-default-swap spread—a measure of the cost of insuring its debt—reached its highest level since October 2022. The stock has fallen almost by half since the start of September.

"Institutional investors like us are really focused on regulatory stability," said Andrea Valeri, Blackstone (NYSE:BX)'s country chairman for Italy and chief investment officer for private credit in Europe and APAC, at a recent conference. "Italy in this regard has been on a very steady growth trajectory." His comments, while about Italy, underscore a broader flight to certainty as AI bets face turbulence.

SoftBank's exposure extends beyond OpenAI. Its roughly 90% stake in Arm (NASDAQ:ARM), the chip designer, and its data-center investments tie its fortunes to multiple layers of the AI stack. That integration could amplify gains if AI demand produces durable profits—or magnify losses if competition compresses returns.

Competitive Pressures

OpenAI faces stiff competition, particularly from Anthropic in coding and enterprise markets. Reuters' April report linked some of OpenAI's missed targets to losing ground to rivals. Growing AI demand does not guarantee that one provider captures enough revenue to justify its commitments.

The October 28, 2025, recapitalization of OpenAI's commercial business into a public benefit corporation (OpenAI Group PBC) preserved nonprofit control through the OpenAI Foundation. California and Delaware regulators negotiated conditions that require mission-first consideration in safety and security decisions. These protections matter because outside investors like SoftBank hold economic interests without necessarily controlling the company's mission.

Regulatory and Geopolitical Risks

Cross-border regulatory risk is another concern. China blocked the proposed $5.4 billion sale of ABB (SIX:ABBN)'s robotics business to SoftBank, with reporting linking Chinese concerns to robotics data potentially being transferred abroad for AI training. That affects SoftBank's broader "physical AI" strategy.

Meanwhile, the U.S. midterm election results have increased investor concern about slower data-center development, according to Reuters. Futurum Group analyst Rolf Bulk argued that near-term demand and many already-approved 2027 projects were less exposed, while later development faced greater political uncertainty.

What's Next

The key issues are whether OpenAI closes another round on the reported terms, whether its revenue trajectory supports computing commitments, and whether SoftBank can fund its strategy without further pressure on borrowing costs. Reporting that OpenAI's public offering has moved to 2027 also extends the period before a potential public-market liquidity event.

Asymmetric Advisors strategist Amir Anvarzadeh told Reuters that the selloff might be near a short-term bottom but warned that evidence of slower development could cause shares to revisit their lows next year. Bulk was more reassuring about already-advanced infrastructure projects while acknowledging greater uncertainty further out.

The central trade-off is between strategic integration and concentrated risk. SoftBank's model, chip and infrastructure exposure could reinforce one another if AI demand produces durable profits. The same connections could amplify losses if model competition compresses returns.
