OpenAI IPO delay reported, AI chip stocks tumble
The New York Times reports that OpenAI is delaying its IPO to 2027. AI chip stocks plunge in early trading: Broadcom -3%, AMD -5%, Micron -7%, Sandisk -10%.
Partial recovery in chip stocks
By the end of the session, Broadcom closes up 2.10%, AMD down 2.50%, Micron down 5.16%, and Sandisk down 8.14%, paring some losses.
SpaceX IPO whipsaw
SpaceX goes public; stock closes first day up 19%, then surges as much as 50% above offering price before losing most gains, creating volatility that spooks other IPO candidates.
The sharp sell-off in AI chip stocks after OpenAI’s IPO delay highlights the AI industry’s deep dependence on a handful of well-funded labs. With OpenAI pausing its public entry, the pace of infrastructure expansion for next-generation models could moderate, posing risks for both chipmakers and the AI research community. Yet the long-term demand story remains intact, even if the near-term funding pipeline looks choppier.
