Replit, a popular AI coding platform for developers and startup founders, announced that it is no longer collaborating with Anthropic, according to CEO Amjad Masad speaking at TechCrunch Disrupt on October 16, 2026. Masad cited multiple factors influencing this decision, including performance, partnership alignment, and especially cost considerations. While Replit had publicized a new partnership with OpenAI in August, there had been no explicit statement about ending its work with Anthropic until now.

Prior to this update, Replit had been leveraging Anthropic’s Claude models to power its cloud-based development interface, a partnership that reportedly helped Replit multiply its revenue tenfold. However, despite Masad’s comments, some insiders familiar with the alliance disputed that it had ended, noting continuing use of Anthropic models on Replit’s platform through late September, as reflected in company blog posts and employee social media sharing.

Masad also shared insights on Replit’s growth, noting a significant shift in its revenue mix toward enterprise customers. While enterprise contracts accounted for about 2% of revenue last year, this share grew to approximately 15% in 2026, and currently over half of all revenue now comes from business-to-business clients. He emphasized the importance of building secure, well-orchestrated environments to deploy AI safely, comparing AI agents’ habitat needs to those of human workers.

Overall, Replit’s pivot away from Anthropic underscores the complexities of balancing tech partnerships and performance deliverables in the evolving AI platform market. The company's embrace of OpenAI models reflects its strategy to optimize cost and enhance capabilities, even as some uncertainty remains about the full status of the Anthropic collaboration. Replit continues to focus on growing its enterprise base while prioritizing AI safety and operational reliability.
