Anthropic’s recent IPO filing has pulled back the curtain on a complex and potentially risky business model defined by a deep entanglement with industry giants. While the AI startup has seen explosive growth—with revenue jumping 12-fold to $4.6 billion in 2025—nearly half of those sales were routed through cloud partners Amazon and Google. These companies serve a triple role as vital distribution channels, massive investors, and direct competitors in the race to dominate artificial intelligence. While this strategy allows Anthropic to tap into pre-existing global sales networks, it creates a circular financial dependency that exposes the firm to potential conflicts of interest and significant supply chain vulnerabilities.

The company’s path forward is marked by staggering capital requirements, with long-term commitments for computing capacity ballooning to over $417 billion by early 2026. This aggressive spending underscores the tension between scaling rapidly and maintaining independence. Furthermore, the prospectus highlights a lack of diversification in its revenue streams, noting that a significant portion of income relies on a small number of customers without long-term contracts. As Anthropic seeks a multi-trillion dollar valuation, it must balance these massive infrastructure costs against the reality that its two biggest cloud partners—who also process a majority of its outstanding bills—hold significant power over its market access and future profitability.
