OpenAI Shelves IPO Citing AI Security Risks, Backs Pause

OpenAI has decided against an IPO this year, attributing the move to AI security risks and joining Anthropic in advocating a pause on further advancement to maintain human control. The decision reverses prior market expectations of a near-term listing and signals heightened regulatory and safety concerns within frontier AI firms. The financial impact is uncertain, but the move may delay liquidity events and reshape investor sentiment toward AI valuations.
