# AI Infrastructure Stocks Tumble After OpenAI Revenue Miss Sparks Spending Doubts

A single Wall Street Journal report about OpenAI missing its revenue and user growth targets sent shockwaves through the AI infrastructure complex on Monday, wiping billions of dollars off the market capitalizations of data center operators, cloud providers, and chipmakers in a broad selloff that laid bare the fragility of the AI spending thesis.

Iren, the vertically integrated data center operator pivoting from Bitcoin mining to AI cloud services, bore the brunt of the damage, closing at $44.44 after falling 8.11% on the session. The stock was hit by a double blow: renewed fears about the sustainability of AI infrastructure demand and a price target cut from Bernstein, which slashed its target by $25 to $100 per share. CoreWeave, the AI cloud provider that holds an $11.9 billion infrastructure contract with OpenAI, dropped 5.83% to close at $105.53. Nebius Group sank 6.52% to $135.51. In Tokyo, SoftBank shares tumbled roughly 10% in one of the conglomerate's worst single-day declines in recent memory. Oracle, which signed a cloud computing deal with OpenAI worth an estimated $300 billion over five years, fell 7.7% in premarket trading.

The S&P 500 slipped 0.49% to 7,139, while the tech-heavy Nasdaq Composite lost 0.90% to finish at 24,664, dragged lower by a 2-to-5% decline across semiconductor names including Nvidia, AMD, and Broadcom.

The Catalyst

The trigger was straightforward but devastating in its implications. OpenAI failed to hit an internal goal of reaching one billion weekly active users for ChatGPT by the end of 2025 and missed several monthly revenue targets earlier this year. The company's CFO, Sarah Friar, reportedly warned colleagues that she is worried the company may not be able to pay for future computing contracts if revenue does not grow fast enough. OpenAI expects to burn through roughly $25 billion in cash in 2026 against projected revenue of $30 billion, a margin of error that spooked investors who had been counting on exponential demand growth to justify the industry's massive capital commitments.

John Belton, portfolio manager at Gabelli Funds, characterized the report as "largely a rehash of what we already knew: OpenAI's growth seems to have slowed in late-2025 into early-2026 as the business ceded some share to Anthropic and Gemini." But even a rehash was enough to puncture market confidence when valuations across the AI infrastructure chain had been priced for perfection.

Bloomberg Intelligence analyst Anurag Rana offered a more cautionary take, warning that the miss "will have an impact throughout the entire AI infrastructure ecosystem, with Oracle as the most exposed in terms of risk to its financial goals."

The Bernstein Downgrade

Adding fuel to the fire, Bernstein analysts cut Iren's price target from $125 to $100, citing a scaling back of Bitcoin mining operations and dilution from recent equity issuances. While the firm reaffirmed Iren as its top pick among AI-focused miners and expressed confidence in the company's transformation into a superscale AI cloud provider, the timing of the downgrade amplified the day's negative sentiment. For a stock that had become a proxy for the AI data center buildout, the combined hit of macro fears and a reduced target proved too much for bulls to absorb.

The Deeper Question

Monday's selloff exposed a tension that has been simmering beneath the surface of the AI trade for months. The entire infrastructure buildout, from hyperscale data centers to next-generation GPU clusters, has been premised on the assumption that demand for AI compute will grow faster than supply. CoreWeave has projected capital expenditures between $30 and $35 billion for 2026, more than double its 2025 spending. Oracle, SoftBank, and others have made similarly aggressive commitments. Much of that spending is anchored, directly or indirectly, to OpenAI's anticipated compute consumption.

If OpenAI, the single largest consumer of AI compute on the planet, cannot convert its first-mover advantage into the revenue trajectory it promised, the downstream implications are severe. Cloud providers risk building capacity that goes underutilized. Data center operators face the prospect of long-term contracts with a customer whose ability to pay is now openly questioned by its own CFO. Chipmakers must contend with the possibility that order growth decelerates sooner than their forward guidance suggests.

The competitive landscape is also shifting faster than the infrastructure thesis anticipated. Anthropic's Claude has carved out a dominant position in enterprise and developer markets, while Google's Gemini has leveraged its distribution advantage across Search, Android, and Workspace to erode ChatGPT's consumer lead. The AI market is growing, but the spoils are being divided among more players, which means no single company's infrastructure appetite can be treated as a reliable proxy for total industry demand.

What Comes Next

Investors should brace for a period of heightened scrutiny. Earnings season is in full swing, and any softening of AI infrastructure spending guidance from the hyperscalers would extend this pullback well beyond the OpenAI orbit. The coming weeks will determine whether Monday's selloff was a healthy repricing of overstretched expectations or the opening tremor of a deeper correction in the AI trade. For now, the market has delivered its verdict: when the biggest customer in the room admits it may have trouble paying the bill, everyone holding a shovel gets nervous.
