Anthropic Acquires Bun JavaScript Runtime as Claude Code Hits $1B ARR
Anthropic has acquired Bun, the high-performance JavaScript runtime and all-in-one toolchain founded by Jarred Sumner in 2021, to accelerate Claude Code's infrastructure. Claude Code reached $1 billion in annualized run-rate revenue in November 2025, just six months after its May 2025 general availability launch. The acquisition deepens an existing partnership—Bun was already integral to Claude Code's infrastructure scaling and its native installer launch. Bun will remain open source and MIT-licensed, with Anthropic committing continued investment in the project.
Anthropic Acquires Vercept to Advance Claude's Computer Use Capabilities
Anthropic has acquired Vercept, a team specializing in AI perception and interaction for computer use tasks, whose co-founders include Kiana Ehsani, Luca Weihs, and Ross Girshick. Vercept will wind down its external product and join Anthropic to push computer use capabilities further. The announcement coincides with the launch of Claude Sonnet 4.6, which achieved 72.5% on the OSWorld benchmark—up from under 15% in late 2024—approaching human-level performance on tasks like navigating spreadsheets and completing web forms. This follows Anthropic's earlier acquisition of Bun and is part of a broader strategy to build agentic, multi-step task capabilities into Claude.
