Jim Cramer warned on Thursday that Broadcom's AI business, particularly its ambitious fiscal 2028 AI revenue target of $230 billion, is heavily reliant on Anthropic, an AI company that is not publicly traded. Broadcom expects its AI semiconductor revenue to reach approximately $115 billion in fiscal 2027 and then double to $230 billion in fiscal 2028, with Anthropic projected to become its largest XPU customer. Cramer emphasized that investing in Broadcom today is effectively a bet on an Anthropic IPO, which has not yet been filed. Following these comments, Broadcom's stock fell 4% on Thursday, while NVIDIA, with its more diversified customer base, rose 2%.
