AI Giant Anthropic Files for Confidential IPO
5 Jun
Summary
- Anthropic filed confidentially for an IPO, signaling public market intentions.
- Annualized revenue surged to $47 billion, a significant increase from last year.
- The company partners with xAI for compute, costing $1.25 billion monthly.

Anthropic, a rapidly growing AI model maker, has taken preliminary steps toward a public listing by filing confidentially for an initial public offering (IPO). This decision comes after the company secured a significant $65 billion fundraise at a $965 billion valuation, which reportedly experienced strong private investor demand and was oversubscribed.
Co-founder Daniela Amodei cited the substantial capital requirements for training AI models and serving inference as the primary driver for seeking public markets. She believes the public market is well-suited to provide the necessary funding for companies advancing AI frontiers. Anthropic's annualized revenue has shown explosive growth, crossing $47 billion as of May, a substantial leap from approximately $9 billion at the end of 2025.
Despite potential concerns about corporations reining in AI spending, Amodei expressed optimism about AI's future use cases in driving efficiency and creativity across sectors like coding, financial services, legal, and healthcare. She anticipates AI becoming more integrated into daily work, unlocking further value. Unlike some rivals, Anthropic is not building its own data centers, preferring to manage compute capacity carefully.
In a notable development, Anthropic partnered with Elon Musk's xAI for compute capacity. This deal, disclosed in SpaceX's S-1 filing, is set to cost Anthropic $1.25 billion per month. This strategic move aims to secure necessary resources without overextending on speculative compute investments.
