Anthropic reported $16.8 billion in third-quarter revenue for 2026, marking a 45% sequential increase and bringing its run rate to $67 billion ahead of a planned public stock offering. However, slowing growth rates and massive infrastructure commitments have prompted potential investors to weigh valuations below initial targets.
Anthropic executives met with prospective IPO investors at the company’s San Francisco headquarters on Wednesday, Oct. 14, 2026, to present the latest financial disclosures ahead of a share sale targeted for November. The figures show that revenue climbed to $16.8 billion in the third quarter, up from $11.6 billion in the second quarter and $4.7 billion in the first. The company also reported being profitable on an adjusted basis for the second consecutive quarter.
Combined revenue for the first three quarters reached about $33.1 billion. The third-quarter advance brought an increase of $5.2 billion in just three months, though the sequential growth rate fell short of the jump seen in the second quarter, when revenue more than doubled from the first.
Despite the rapid climb, the sequential growth rate slowed from the triple-digit percentage gains seen earlier in the year. That deceleration, paired with heavy capital expenditure plans, has caused some financial backers to reconsider the high valuations discussed earlier in the year. On the same day the company disclosed its partial financial figures, the Nasdaq Index fell 1.88% and the S&P 500 Index fell 1.11% following U.S. inflation data that raised concerns about potential Federal Reserve interest rate hikes.
San Francisco Investor Day Reveals Valuation Pushback
Attendees at the investor gathering, which included Chief Executive Officer Dario Amodei and Chief Financial Officer Krishna Rao, discussed a potential market capitalization of around $1.5 trillion. That figure represents a step down from the roughly $2 trillion valuation that investors had previously anticipated for the upcoming listing, while earlier market expectations in the first half of the year had circulated a prior valuation of $965 billion.
Independent financial research firm New Constructs issued a harsher assessment in a recent note, valuing the company at $150 billion—roughly 93% below the target discussed by market optimists. The firm cited the prospectus’s warning of existential risks, billions in historical losses, and hundreds of billions in contractual obligations.
A lot of people got hosed. A lot of people got scammed. It was terrible. Like, can we not keep doing this revisionist talk saying it was great?

Supply Chain Realities and Upstream Capacity Limits
The broader debate over Anthropic’s market debut centers on whether physical infrastructure can support projected revenue growth. Jon Culpan, a supply chain analyst cited in market commentary, questioned the math behind high valuations by pointing to upstream component suppliers and warning that IPO proceeds will not cover the next few years of artificial intelligence capital expenditures.
A trillion dollars of revenue coming out, I just don’t understand. I just don’t get it. Where is it coming from? Who’s paying for that?
Culpan noted, pointing out that chipmakers and contract manufacturers like TSMC and Foxconn are not scaling their operations by orders of magnitude to match software projections.
According to leaked prospectus data from late September, Anthropic recorded $4.6 billion in revenue for 2025 alongside a net loss of $42 billion and an operating loss exceeding $8 billion. That period included significant spending on computing and infrastructure.
Broader Market Pressures and Competitor Stances
The financial disclosures arrive as macroeconomic headwinds challenge the technology sector. On Oct. 14, the U.S. Bureau of Labor Statistics reported that the Consumer Price Index rose 3.7% year-over-year, while wholesale inflation accelerated to 6.3% annually in September, fueling concerns over Federal Reserve interest rate policy.
Rival artificial intelligence developer OpenAI has taken a different approach to the public markets. Sam Altman, CEO at OpenAI, told Fortune that his company would not pursue an IPO this year, pointing to safety considerations and market conditions.

With Anthropic pressing forward toward its scheduled November share sale, market participants remain divided over whether the company’s rapid enterprise adoption can permanently outpace the staggering capital expenditure required to train and run frontier models.
