OpenAI is considering a slowdown in developing its most advanced artificial intelligence models, according to reports. The strategic shift threatens revenue projections for Nvidia and cloud providers who have bet heavily on accelerating AI infrastructure buildout.

Nvidia shares dropped 2.4 percent to $218.36 today on the news. Meta Platforms fell 1.4 percent to $644.38. Both have been key beneficiaries of aggressive capex spending by cloud hyperscalers racing to deploy large language models at scale.

The deliberation signals a re-evaluation of the aggressive "race to the top" in AI capabilities. Regulatory scrutiny and safety concerns surrounding powerful AI systems may be driving the internal assessment. A deceleration could mark a maturation of the AI development cycle, shifting focus from raw compute power to deployment efficiency and safety protocols—a direct threat to the capex forecasts hyperscalers provided to investors.

Microsoft, which invested $13 billion in OpenAI, rose 0.2 percent to $492.44. Its diversified revenue base, particularly Azure and enterprise software, cushions it against a direct hit from OpenAI's slowdown. Pure-play AI infrastructure providers face sharper risk. Bank of America maintained a "Buy" rating on Nvidia but flagged potential for a "modest re-rating" if long-term AI compute demand softens. The firm's $1,050 price target assumes continued rapid expansion of AI infrastructure.

OpenAI has not issued a formal statement. The company's developer conference scheduled for early next year should provide clarity on its strategic roadmap and development timelines.
