Anthropic quarterly revenue hits $16.8B, growth slowdown questioned

KEY FACTS

  • Anthropic disclosed to investors that its revenue for the last quarter was $16.8 billion.
  • The figure grew significantly from the prior quarter, but the quarter-over-quarter growth rate was lower than from Q1 to Q2.
  • Geiger Capital posted a chart on X and said the growth rate was not good enough.
  • Gary Marcus, Andrew Yang and others publicly questioned the impact of this data on the AI high-growth narrative.
  • Andrew Yang noted that a quarterly revenue growth rate of about 45% would disappoint the market.

PHYSIX OBSERVATION

$16.8 billion is not low in itself, but the market buys the growth curve, not the absolute number. The quarter-over-quarter slowdown is being read as a signal that the AI hypergrowth narrative is loosening, and combined with IPO expectations, any deceleration will be magnified. For the industry, the real test is not a single quarter's figure but whether the next quarter can reaccelerate; otherwise, valuation-correction pressure will spread from Anthropic to the entire AI sector.
