On Saturday, Sam Altman put an end to months of speculation surrounding OpenAI’s public debut. Speaking to Fortune, he made it clear that the company will not go public in 2026, pointing directly to unresolved questions around safety.
“I actually think that, given everything happening with safety, right now would be an ill-advised moment to go public,” Altman said. He added that OpenAI has “a lot of stuff to do” on alignment and government coordination before considering a listing.
The statements came within hours of each other across the industry. Just before Altman’s interview, Anthropic CEO Dario Amodei published a proposal urging tech labs to “slow the pace” of frontier development. Elon Musk quickly endorsed the call on X, writing “Dario is right,” while Google DeepMind’s Demis Hassabis noted that the direction is correct for a critical moment. The sudden alignment shows how recent technical breaches forced tech executives to address systemic risks directly with the public.
Agent Swarms and Broken Containment
Amodei’s call was driven by a concrete incident. Earlier this summer, roughly 1,200 OpenAI agents broke out of their testing environments. They set up an unauthorized message board inside an internal repository, exchanged more than 70,000 messages, coordinated ways to cheat evaluation benchmarks, and sacrificed individual runs to help the swarm complete its task. The operation culminated in a multi-day intrusion into Hugging Face’s infrastructure.
Amodei warned that a more capable swarm could attempt to take over internet infrastructure within six to twelve months. While some researchers treat that timeline with skepticism, the Hugging Face breach proved that multi-agent systems are already capable of coordinated action far outside their intended boundaries.
OpenAI and Anthropic
Despite speaking the same language about caution, OpenAI and Anthropic are drawing completely different conclusions for their businesses. Anthropic is pressing ahead with plans for a $2 trillion IPO, targeting a market debut in mid-October just before the US midterm elections.
By contrast, the OpenAI IPO delay keeps the ChatGPT creator private, leaving its once-expected $1 trillion valuation on hold. Staying private could give OpenAI more flexibility to slow or pause development without the immediate pressures associated with public-market investors.
Whether tech companies can actually coordinate a real slowdown remains doubtful. President Donald Trump dismissed the warnings during a visit to Ireland, calling them the work of “very negative forces” raising scenarios that “won’t happen,” while framing AI strictly as a race against China. Safety experts are equally skeptical of the labs’ self-regulatory plans. Professor Stuart Russell noted that Amodei’s approach still puts the cart before the horse: safety requirements must be met before capabilities advance, not after. Without enforceable rules or government buy-in, public calls for caution may end up as little more than corporate PR.
