• Anthropic's revenue growth decelerated sharply in Q3 2026, but total revenue still climbed to $16.8 billion, up 45% sequentially.
  • D.A. Davidson analysts Gil Luria and Turner Dischinger attribute the slowdown to rising competition from OpenAI and open-weight models, not a broader AI demand slump.
  • The company also disclosed at least $518 billion in infrastructure commitments, underscoring that AI investment remains on a steep upward trajectory.

A Deceleration, Not a Collapse

Anthropic’s revenue growth has slowed sharply, but the sky is not falling. According to details presented at a pre-IPO investor meeting in San Francisco on October 14, the AI developer generated $16.8 billion in the third quarter of 2026, a 45% increase from the prior quarter. That’s down from a blistering 145% sequential jump in Q2, when revenue hit $11.6 billion, and up from $4.7 billion in Q1.

While the percentage slowdown is eye-catching, Anthropic still added roughly $5.2 billion in new quarterly revenue—a figure larger than the total quarterly sales of most enterprise software companies. D.A. Davidson analysts Gil Luria and Turner Dischinger argue the deceleration should not be read as a sign of softer AI demand. Instead, they point to growing competition from OpenAI and open-weight AI models, as businesses diversify their spending across multiple providers.

“The update was more mixed than the market’s negative reaction suggested,” Luria said in a note, highlighting that Anthropic also reported positive third-quarter cash flow on an adjusted basis.

The Math of Scale

A company cannot grow at triple-digit percentages forever. As revenue balloons, maintaining that pace becomes mathematically harder. Anthropic’s base has expanded nearly fourfold in two quarters, making a 45% sequential gain equivalent to adding a mid-sized software firm’s entire annual revenue in just three months.

Still, the slowdown has raised eyebrows in a sector where valuations often assume hypergrowth. The lack of audited quarterly earnings—the figures come from a private investor presentation—adds to the uncertainty. Anthropic’s CFO, Krishna Rao, joined CEO Dario Amodei in delivering the numbers, according to Reuters (TRI), which cited an investor who attended the meeting.

What the headline misses is that overall AI investment remains robust. Anthropic’s decade-long infrastructure commitments now total at least $518 billion for cloud services, computing, and data-center capacity. Those obligations, while not guaranteed spending, signal that demand for compute power is still climbing.

Competitive Pressures and Regulatory Headwinds

The rise of open-weight models—freely available and customizable—has given enterprises more options, allowing them to spread workloads across providers rather than committing to a single vendor. This diversification could explain some of Anthropic’s deceleration. But the available data cannot disentangle lost market share from pricing pressure or capacity constraints.

Anthropic also faces company-specific policy risks. A February 2026 presidential directive instructed federal agencies to stop using its technology, and the Pentagon designated it a supply-chain risk. In June, foreign access to its Mythos 5 and Fable 5 models was restricted, then lifted on June 30. Anthropic has challenged the Pentagon action in court. In its IPO prospectus, the company warned that government attitudes could damage relationships with commercial partners.

Market conditions aren’t helping. September U.S. inflation came in above expectations, stoking fears of higher borrowing costs for capital-intensive AI projects. On October 15, semiconductor shares came under pressure, with the SOXX ETF down roughly 12% over the prior seven sessions. Japanese tech investor SoftBank (SFTBY) and South Korean chipmakers Samsung (005930.KS) and SK Hynix (000660.KS) also saw sharp declines, reflecting broader AI-spending and inflation concerns.

What to Watch

Anthropic is reportedly targeting a valuation above $2 trillion for its proposed IPO, which Reuters expects to occur after the November U.S. midterm elections. The listing would test public-market appetite for a company that, despite generating positive adjusted cash flow, still faces enormous infrastructure obligations.

For now, the evidence supports the D.A. Davidson view: Anthropic’s slower growth does not prove an AI-demand collapse. But it also does not prove that all AI investments are immune to competitive and financing pressures. The coming quarters will reveal whether the company can sustain its torrid expansion—and whether investors will reward it for doing so.

Update: An earlier version of this article incorrectly stated the sequential growth rate for Q2. It was approximately 145%, not 135%.
