Anthropic Growth Accelerates Despite Regulatory Pressure and Rising AI Costs

Anthropic declined to comment.

The artificial intelligence startup, led by Dario Amodei, filed documents with the Securities and Exchange Commission in June and entered a quiet period that limits public disclosures about its financial performance.

Anthropic has strengthened its position against major AI competitors OpenAI and Google this year. The company released a model that outperformed rival systems while maintaining a strong focus on enterprise customers. In May, Anthropic reported annual revenue of more than $47 billion.

Venture capital firms, sovereign wealth funds and other institutional investors invested just under $100 billion in Anthropic during 2026. The company’s valuation exceeded OpenAI’s for the first time in May, reaching $965 billion after new investments were included.

Despite its rapid growth, Anthropic faces considerable uncertainty. The company has repeatedly clashed with the Trump administration and is pursuing an active lawsuit against the US Department of Defense, which designated Anthropic as a supply chain risk earlier this year.

Anthropic also faced export restrictions from the Department of Commerce in June and was forced to temporarily withdraw its flagship Fable 5 and Mythos 5 models. The disruption surprised some customers that depend on Anthropic’s AI systems.

At the same time, customers are becoming more sensitive to the cost of accessing advanced AI models. As expenses rise, some companies have reversed earlier instructions encouraging employees to maximize their use of AI tools and have instead adopted lower-performing, less expensive models.

According to Artificial Analysis, which evaluates AI models, Anthropic’s leading system costs more than 2.5 times as much to use as OpenAI’s flagship model. China’s Indiscriminate model, which also improved significantly this year, is available at a fraction of the price.

Anthropic increased its market share among US companies last month, according to data from payments company Ramp. However, Ramp’s analysts said businesses had “reached the limits of their AI spending” and were increasingly turning to cheaper alternatives.

“It’s easy to come up with challenges,” said an Anthropic investor who also backs AI companies including OpenAI and SpaceX, which went public in June at a valuation of $1.77 trillion. “But the company continues to be number one in performance, positioning and what people want to know.”
