AI model maker Anthropic is experiencing a period of intense growth, attracting significant private investment that has seen investors eager to secure a stake in the company. Multiple sources confirm that Anthropic's recent $65 billion fundraise, which valued the company at an impressive $965 billion, was substantially oversubscribed. Capitalizing on this sustained private demand, Anthropic has now initiated steps toward becoming a publicly listed company by filing confidentially for an Initial Public Offering (IPO).

Daniela Amodei, co-founder of Anthropic, elaborated on the strategic decision during the Bloomberg Tech conference, emphasizing the critical need for capital. She explained that the costs associated with training sophisticated AI models and serving their inference are exceptionally high. Amodei posited that core companies pushing the boundaries of AI will inevitably require considerable access to capital, a need she believes the public market is uniquely positioned to fulfill.

The company's financial trajectory underscores its rapid expansion, with annualized revenue reported to have surpassed $47 billion in May, a dramatic increase from approximately $9 billion recorded at the end of 2025. However, this aggressive growth path faces potential scrutiny. Some corporations, such as Uber, have indicated that while AI can yield returns, not all AI-related expenditures have proven productive. This sentiment raises the possibility that businesses might begin to moderate their AI budgets, potentially slowing sector-wide growth.

Despite these potential headwinds, Amodei maintains an optimistic outlook, suggesting that the business community is still in the nascent stages of effectively deploying AI technologies. She anticipates that current applications in areas like coding, financial services, legal, and healthcare will continue to be primary drivers of efficiency and creativity. Amodei's hope is that as businesses become more adept with AI tools, the technology will become increasingly integrated into the daily workflow of individuals, ultimately realizing significantly greater value.

Regarding the infrastructure required to meet its escalating compute demands, Anthropic has adopted a distinct approach compared to rivals like OpenAI and Elon Musk's xAI, choosing not to construct its own data centers. Amodei clarified Anthropic's philosophy: to plan for optimal outcomes without overextending by acquiring more compute capacity than can be productively utilized. Acknowledging the inherent difficulty in perfectly predicting future needs, she stated a preference for a scenario where demand for their product slightly exceeds their service capacity, rather than the reverse.

Further demonstrating this strategy, Anthropic recently surprised the AI industry by announcing a partnership with xAI for compute capacity. This significant agreement, later detailed in SpaceX's S-1 filing, stipulates a cost of $1.25 billion per month for Anthropic's access to xAI's computing resources.
