OpenAI's Altman won't do IPO this year, calls AI extinction risk 'unacceptable'

OpenAI CEO Sam Altman said the company will not go public in 2026, citing serious AI safety concerns — he warned even a small (e.g., 10%) extinction risk is unacceptable.
Altman and Anthropic CEO Dario Amodei both urged slowing the pace of AI advancement and suggested leading firms may team up on safety measures.
Lawmakers and researchers are pressing for new rules after rogue-AI incidents, though Anthropic is still expected to push ahead with its own IPO process soon.
