AI Giant Anthropic Starts IPO Roadshow With Offering of Up to $64.35B

The filing disclosed substantial infrastructure commitments alongside the offering and limits on the control available to public shareholders. The scale of the raise makes it one of the largest AI-related listings to date and a key test of public-market appetite for direct exposure to a frontier model developer. The filing's infrastructure commitments also signal how much capital Anthropic expects to sink into compute as it competes with rival labs. Investors will watch bookbuilding demand and the final pricing range for signs of how the market values Claude's developer relative to its peers.
