19 reports11 sources10/29/2026 updated

Current overview (not historical)

AI overview

Anthropic plans a November 2024 IPO, with its valuation dropping from an initial $2 trillion to $1.5 trillion as the company reports slowing revenue growth. Third-quarter revenue reached $16.8 billion, up 50% year-on-year, but the growth pace has decelerated. The company highlights a significant improvement in Compute efficiency, with each dollar of computing power generating $1.70 in revenue, up from $0.63 a year ago. Major clients such as Meta and Microsoft are shifting toward in-house models, while Claude Haiku 5.5 pricing was cut by 75%. Despite these challenges, Anthropic maintains its IPO filing and plans a Nasdaq listing under the ticker 'ANT'.

    VCs eye billions as Anthropic prepares for IPO, but Amazon stands to profit far more via convertible notes

    Report first recorded Oct 28, 10:04

    Anthropic's S-1 filing reveals that venture firms including Menlo Ventures and Sequoia are expected to return billions from the IPO, yet none hold a 5% stake, a highly unusual situation for a tech IPO. Instead, Amazon emerges as the primary financial beneficiary, holding convertible notes with $6.2 billion in principal that the S-1 valued at $97.9 billion as of June 30. Amazon further invested $10 billion in non-voting preferred stock during the second quarter, bringing its total investment to approximately $18 billion. Beyond stock gains, Amazon is committed to spending at least $110 billion on its AWS cloud platform over the next decade.

    Anthropic's IPO filing reveals a $265.5 billion commitment to cloud providers Google, Amazon and Microsoft, roughly 16 times its $16.3 billion in first-half revenue.

The company reported $16.3 billion in revenue for the first half of 2026, up from $1.2 billion in the same period of 2025, but recorded a net loss of $80.7 billion, largely driven by noncash accounting adjustments related to convertible debt.

    Anthropic IPO valuation expected at $1.5 trillion, lower than initial $2 trillion projection

    Report first recorded Oct 16, 13:52

    Investors attending Anthropic's investor day in San Francisco reported a valuation around $1.5 trillion for the November listing, significantly lower than the previously expected $2 trillion. Anthropic reported third-quarter revenue of $16.8 billion, a 45% rise, and stated it was profitable on an adjusted basis. However, the growth pace slowed from $11.6 billion in the second quarter, partly due to large clients like Meta and Microsoft building their own AI models, and Anthropic cutting back on distillation, which accounted for 5% to 7% of revenue. Furthermore, Anthropic priced Claude Haiku 5.5 about 75% below its predecessor amid pressure from low-cost Chinese labs. Despite the lower valuation, $1.5 trillion is still below SpaceX's $1.77 trillion valuation from its June listing.

    Anthropic Reports $16.8B Q3 Revenue Amid Slowing Growth Ahead of November IPO

    Report first recorded Oct 15, 18:44

    Anthropic achieved $16.8 billion in third-quarter revenue, a roughly 45 percent jump from the second quarter, though growth has slowed compared to the Q1-Q2 surge driven by Claude Code demand. The company reported an adjusted operating margin of 11% for the year through Q3 and is cash-flow positive, generating $1.70 in revenue for every dollar spent on compute. Anthropic estimates 5 to 7 percent of its revenue comes from distillation, which is expected to decline following the rollout of countermeasures. The planned November IPO faces investor skepticism due to slowing growth, despite the company's private valuation reaching $965 billion in May.

    Anthropic Reports Revenue Growth Slowdown Ahead of $2 Trillion IPO Pitch

    Report first recorded Oct 15, 13:29

    Anthropic reported $16.8 billion in revenue for the third quarter, a 50% increase, alongside a second straight adjusted profit and 11% operating margins. This marks a significant improvement from 2025, where the company generated roughly $0.63 in revenue for every $1 spent on compute, compared to $1.70 in the third quarter. Despite this, revenue growth has slowed compared to earlier this year, and forecasts for year-end revenue have been revised down by SemiAnalysis to roughly $74 billion. Pressures include large clients like Meta and Microsoft developing in-house models, a reduction in distillation revenue (5% to 7% of revenue), and a price war involving OpenAI and low-cost Chinese labs. Anthropic plans its IPO in November, targeting a valuation above $2 trillion, with Goldman Sachs and Morgan Stanley reportedly leading the offering.
