News that OpenAI failed to meet several key targets — including user numbers and revenue — prompted declines in multiple stocks. Because many companies rely on contracts with the AI startup for significant revenue, the firm’s underperformance set off knock-on effects across its supplier and investor network.
Who was affected and by how much
SoftBank, one of OpenAI’s largest investors, saw its shares fall by nearly 10 percent on the Tokyo Stock Exchange after the announcement. The drop came amid recognition that the Japanese firm has invested tens of billions of dollars in Sam Altman’s company.
In U.S. pre-market trading, several OpenAI-linked stocks also weakened. Oracle and CoreWeave — firms that develop data-center solutions for OpenAI — fell by roughly 5 percent. Microsoft, an early supporter of the startup, experienced a comparatively small decline of around 0.5 percent. Chipmakers that supply OpenAI, including AMD and Nvidia, also saw share-price weakness to varying degrees.
Bloomberg’s summary noted that companies tied to OpenAI have underperformed relative to some peers in recent months: a basket of OpenAI-linked stocks rose about 75 percent since 2024, while an index of firms cooperating with Alphabet (Google’s owner) gained more than 300 percent over the same period.
Market position and competition
OpenAI has long been viewed as a leading AI company, reflected in its high valuation. Recently, however, Google’s Gemini and Anthropic’s Claude models have dominated discussions about artificial intelligence and have been steadily taking market share from ChatGPT and other OpenAI models.
The company has also seen several important departures over recent years; among the founders, only CEO Sam Altman remains at the firm. Additionally, the company has committed to very large expenditures — reported at 1.5 ezermilliárd dollars (1.5 trillion USD) — raising questions among market participants about how those costs will be financed and whether they are sustainable.
Analysts warn that both cutting spending and further increasing outlays could send worrying signals: the former might undermine growth prospects, while the latter could raise doubts about long-term sustainability.
Why this matters
Contracts and integrations with OpenAI are strategically and financially important to many companies. When a major partner falls short of growth expectations, it can reduce revenues for suppliers, worsen investors’ positions, and create openings for competitors. The recent market reaction reflects this chain effect.
Going forward, investors and partners will watch how OpenAI responds to rising competition, what measures it takes to stabilize spending and revenue, and whether it can reclaim a leading role in AI development.
