Investors backing Anthropic, the maker of the Claude family of large language models, expect the artificial-intelligence company to list on public markets as early as October at a valuation of $2 trillion or higher, a level that would surpass the peak private valuation of SpaceX and rank as the largest initial public offering in market history.
NEW YORK, August 14 — Investors backing Anthropic, the maker of the Claude family of large language models, expect the artificial-intelligence company to list on public markets as early as October at a valuation of $2 trillion or higher, a level that would surpass the peak private valuation of SpaceX and rank as the largest initial public offering in market history.
The projection, conveyed by six shareholders to international financial press this week, reflects an extraordinary re-rating of the five-year-old AI laboratory: Anthropic’s valuation in private financing stood at roughly $965 billion in May, when the company briefly overtook OpenAI as the most valuable private AI firm. Less than three months later, the same group of backers is preparing for a price tag more than double that figure.
The pivot rests on revenue. Anthropic’s annualized run-rate revenue, a measure that extrapolates recent monthly sales to a full year, climbed from about $1 billion in January 2025 to $9 billion by year-end, accelerated to $30 billion in April 2026, and crossed $47 billion in May, a forty-seven-fold expansion in under eighteen months. In the second quarter of 2026 the company posted $10.9 billion in revenue, recording an adjusted operating profit of $559 million and turning profitable two years ahead of the timeline it had signaled to its own investors.
The most aggressive forecast circulating among shareholders projects year-end 2026 annualized revenue in the $100 billion to $120 billion range, a more than tenfold increase from the start of the year. At the high end of that range, a $2 trillion valuation would imply a price-to-sales multiple of roughly 17 to 20 times; a more bullish investor model, which assumes revenue growth of 800 percent, places the defensible multiple closer to 30 times and the implied market capitalization near $3 trillion.
“This is the first time a private AI company is being priced against a future cash-flow curve, not against current revenue,” said Marina Chen, senior analyst at a New York-based technology research firm. “Markets are pricing in dominance in enterprise AI, not parity.”
Dominance is, for now, a documented shift. Anthropic’s share of the enterprise large-model API market reached 32 percent in the second quarter, ahead of OpenAI’s 25 percent, marking the first time the company has led the segment. Amazon, Google, JPMorgan Chase and Salesforce are listed among its anchor customers. The Claude Code product line, an AI assistant for software developers, has crossed an annualized run-rate of $2.5 billion as a single product, a figure that places it in the company of the most widely deployed developer tools.
The IPO mechanics are largely settled. Anthropic confidentially submitted its S-1 registration document to the U.S. Securities and Exchange Commission in June, entering the required quiet period. Goldman Sachs, Morgan Stanley and JPMorgan Chase are running the institutional book-building exercise, with the market previously expecting a listing value of about $1 trillion. The doubling of expectations in two months has been driven less by changes in the IPO structure and more by the rapid upward revision of revenue forecasts.
The strategic backdrop is one of accelerated consolidation. Anthropic completed a $30 billion Series G funding round in February, led by GIC and Coatue, lifting the company’s post-money valuation to $380 billion. Earlier commitments from Amazon, which has progressively increased its investment to $8 billion, and from Google, whose cumulative commitment exceeds $2 billion, anchor a long-running partnership structure in which the company draws substantial compute capacity from the same firms whose enterprise customers it serves.
The risks embedded in the projection are considerable. A $2 trillion valuation rests on the assumption that enterprise AI spending continues to expand at a multiple that no software segment has sustained for more than a handful of quarters. Regulatory pressure on frontier-model developers has tightened across the European Union, the United Kingdom and several U.S. states. The collapse of any of the three largest investors — Amazon, Google or the sovereign and hedge-fund cohort that joined the Series G — would, by one analyst estimate, force a re-pricing of more than fifteen percent on listing day.
“The market is treating AI compute as a strategic asset class on par with oil reserves in the 1970s,” Chen said. “That framing supports a $2 trillion price. It also explains why the first quarter of disappointing revenue guidance would not be a soft patch — it would be a regime change.”
Anthropic’s management has not publicly committed to the $2 trillion figure; the range is the product of separate financial models constructed by the company’s early backers. The SEC-imposed quiet period prevents the company from disclosing its own preferred valuation. The October listing window is contingent on the regulator’s approval of the S-1, on the absence of material adverse market conditions, and on a final price discovery process that, given the dispersion of investor models, may be unusually volatile.
The Anthropic offering, if completed at the projected valuation, would also mark a structural shift in the geography of technology listings. A $2 trillion debut would, by one estimate, represent more than seven percent of the total market capitalization of all U.S. listed technology companies at the end of 2025, a concentration that would reset the composition of the leading equity indices.
