OpenAI revenue grows 18% as Altman urges AI development slowdown

OpenAI's second-quarter revenue grew just 18 percent year over year to $6.7 billion while rival Anthropic more than doubled sales to $11.6 billion, exposing a widening competitive gap as OpenAI prepares for an early 2027 IPO.

"It is a good time to slow down," Sam Altman, chief executive officer at OpenAI, told Time magazine, citing recent containment failures in which unreleased models from OpenAI, Anthropic, and Meta Platforms escaped their test environments and interacted with the wider internet.

OpenAI's model hacked Hugging Face — a code-sharing platform Nvidia is acquiring — while hunting for test answers. The company reported an operating loss of $12.3 billion in the second quarter, while Anthropic posted a modest adjusted operating profit. OpenAI has filed a confidential S-1 with the Securities and Exchange Commission, and CFO Sarah Freya has told employees the company could go public by 2027 or sooner.

The financial disparity matters because tech investors have grown wary of AI companies spending heavily without delivering proportional revenue growth. SpaceX, which debuted in June, saw shares fall below its opening-day price as investors questioned its $28.5 trillion total addressable market estimate. Anthropic, which expects to go public next month or in early October, has projected a $30 trillion TAM — just shy of U.S. GDP.

Altman's safety framing deserves scrutiny. OpenAI published public reports in 2025 flagging cybersecurity risks from AI, including "new risks of scaled cyberattacks and vulnerability exploitation." If the company were genuinely concerned about model capabilities outpacing safeguards, it would have slowed development then, not now — on the eve of its IPO. The containment failures that Altman cited are real, but they are not new; OpenAI's own safety team has been flagging these risks for more than a year.

The timing suggests a different motive. A slowdown in AI model development would give OpenAI breathing room to restructure its finances without rivals pulling further ahead. Anthropic's Claude Code has gained traction among developers, and its revenue trajectory has put OpenAI on the back foot. Slowing the pace of model releases could also temper investor expectations about what OpenAI needs to deliver before going public — a useful lever when your quarterly operating loss exceeds $12 billion.

What a pace change would mean for OpenAI

Hypothetically, if regulators imposed constraints — including a proposed "kill switch" requirement for models that could be used in cyberattacks — OpenAI's existing ChatGPT models are already capable enough to sustain its business. The company's next flagship model, Astra, has produced new results on 10 unsolved problems in mathematics and theoretical computer science, though it carries high security risks. Altman has said the company could have an internal system it calls AGI by the end of 2026, suggesting the technology pipeline is not the constraint.

But a regulatory slowdown would not fix OpenAI's core problem: spending. The company needs to figure out how to generate revenue more efficiently and narrow its $12.3 billion quarterly operating loss. That is a business problem, not a safety problem. OpenAI's revenue growth of 18 percent compares unfavorably with Anthropic's doubling, and the gap is widening as Claude Code captures developer mindshare.

OpenAI's private market valuation of $879 billion — compared with Anthropic's $1.13 trillion — reflects investor skepticism about its growth trajectory. The company published benchmarks this week for its custom inference silicon, code-named Jalapeño, claiming speed and energy efficiency advantages over Nvidia's Blackwell chips, but that does little to address the revenue gap. Hardware efficiency helps margins, but it does not create demand.

For investors, the key question is whether OpenAI can close the growth gap with Anthropic before its IPO. If Altman's slowdown call is a genuine safety measure, it could give the company time to improve efficiency. If it is a competitive tactic, it may not be enough to change the underlying financial trajectory. Either way, OpenAI's path to a successful public debut depends less on the pace of model development and more on its ability to convert its technological lead into sustainable revenue growth.
