OpenAI Picked Broadcom for Its First Custom AI Chip. The Race for Number Two Just Got Dangerous.

OpenAI disclosed a chip partnership with Samsung, prompting investors to sell Broadcom shares on concerns that the deal could threaten Broadcom's AI-chip opportunity. The central unresolved issue is whether Samsung displaced any existing or prospective Broadcom business, rather than merely adding capacity or supply options for OpenAI. The news creates a near-term competitive-overhang risk for Broadcom but provides no disclosed evidence of lost revenue or orders.
