The data indicates businesses aren’t rejecting Anthropic wholesale. Rather, organizations are leveraging less expensive alternatives, encompassing legacy Anthropic offerings and open-weight solutions from Chinese rivals, to handle the majority of their workload.

Advanced frontier models are being reserved exclusively for high-complexity assignments. This emerging pattern demonstrates that enterprises are exercising greater discernment regarding when premium-priced tools justify their cost.

Miles Clements, representing venture capital firm Accel—which has committed $1 billion to Anthropic—informed the Financial Times that the period when clients exclusively favored cutting-edge models “was not a durable era.”

The Fable 5 release in June arrived amid significant controversy. Media coverage highlighting its capacity to autonomously execute cyberattacks generated considerable scrutiny, and the Trump administration imposed a temporary prohibition on Anthropic’s foreign sales of the technology citing national security risks, though these limitations were subsequently removed.

Despite the removal of sales barriers, Fable 5’s market penetration has underperformed compared to previous Anthropic model deployments.

Revenue Performance Falls Below Projections While OpenAI Narrows the Distance

By July, Anthropic achieved $65 billion in annualized revenue. This figure represents a shortfall against the $80 billion benchmark certain investors established in anticipation of the company’s forthcoming initial public offering.

Meanwhile, OpenAI has been reclaiming market position it surrendered to Anthropic during the earlier part of the year. The company’s annualized revenue has climbed to $40 billion, propelled by GPT-5.6, a recently introduced model offering lower operational costs compared to Fable 5.

GPT-5.6’s competitive pricing strategy seems to be attracting customers who previously might have remained loyal to Anthropic. Reuters documented that OpenAI slashed developer costs for the model by over 20%.

Certain market analysts contend that Fable 5 expenditure figures present an incomplete picture. Alex Imas from Google DeepMind maintains that Anthropic’s focus centers on aggregate spending across its entire model ecosystem, rather than Fable 5 performance in isolation.

“Spending on Fable can go down and it would still add value if it’s complementary to the other models,” he wrote.

Ara Kharazian, serving as chief economist at Ramp, emphasized the exceptional difficulty in forecasting either company’s trajectory.

“If you impute previous trends you expect Anthropic to own the market. But because OpenAI’s newest model was so good and Fable underperformed, it’s been the reverse,” he told the Financial Times.

This market dynamic emerges during a critical juncture for Anthropic, as the organization advances toward a multitrillion dollar public offering that will demand robust growth metrics to validate its market capitalization.
