Anthropic reported third-quarter 2026 revenue of $16.8 billion, representing a 45% quarter-on-quarter increase and an annualized run rate of $67 billion. However, the company's S-1 filing reveals that 25% of its 2025 revenue originated from two unnamed customers. The firm faces pressure from the New York City Comptroller, who urged a pause on the IPO due to concerns regarding AI safety and existential risks.
OpenAI has officially delayed its IPO until at least 2027, with CEO Sam Altman citing current AI safety concerns as a primary factor. Meanwhile, the broader chip sector experienced a $2 trillion selloff, fueled by skepticism over the high costs of AI infrastructure. Gartner forecasts that AI data center revenue will reach at most $3.6 trillion by 2030, falling short of the $8.5 trillion required to cover investments and returns.
The economic viability of closed-model AI is being challenged by open-weight alternatives. Enterprise adoption of open-weight models reached 67% in 2026, with reported cost savings of 70% to 90%. Research firm New Constructs estimates that justifying Anthropic's $2 trillion valuation would require an annual after-tax operating profit of $358 billion by 2035, alongside a 10% operating margin sustained for a decade.
Market data highlights a disconnect between AI spending and realized returns. While global AI spending is projected to hit $2.59 trillion in 2026, reports from MIT NANDA and KPMG indicate that only 5% to 7% of organizations have achieved a measurable return on investment from generative AI. Anthropic currently holds $518 billion in locked infrastructure commitments.
