AMD commits $2.5 billion to Anthropic IPO, securing 0.2% stake and tying future $20 billion rack spend

Anthropic’s S‑1 filing shows AMD will buy $2.5 billion of Anthropic Class N shares, representing roughly a 0.2 % ownership stake. The purchase is part of a $26 billion private placement and follows AMD’s earlier $5 billion equity pledge to the AI startup. Under a July supply agreement, Anthropic could spend more than $20 billion on AMD Helios racks beginning in 2027. Goldman Sachs named AMD a top semiconductor pick after the filing, and Oppenheimer upgraded AMD to Outperform with a $600 price target.

The equity stake links AMD’s GPU sales to Anthropic’s projected $20 billion rack spend, which could boost AMD’s data‑center revenue (as noted in the filing). Oppenheimer’s upgrade reflects analyst optimism about the partnership’s upside.
