OpenAI acquires Astral
OpenAI is buying Astral — the team behind popular Python tooling — to power its Codex agent while pledging continued OSS support, signaling more agentic developer automation is coming. The deal tightens Big Tech's grip on developer workflows but keeps key open‑source projects in play for now. (m.economictimes.com)
OpenAI and Astral published matching announcements on March 19, 2026 saying the companies have entered into an agreement and that closing is subject to customary closing conditions and regulatory approval. (openai.com) Astral’s public product list names uv, Ruff, and ty as flagship projects, and PyPI traffic shows uv had about 117,651,451 downloads in the last month while Ruff recorded roughly 149,951,925 downloads in the same period. (astral.sh) Astral engineered those tools in Rust for performance — Charlie Marsh’s Jane Street talk and Astral docs emphasize Rust rewrites and low‑level optimizations — and Astral’s ty package advertises “10x–100x” speedups over mypy/Pyright in its PyPI description. (janestreet.com) The Astral engineering blog post authored by founder Charlie Marsh confirms the Astral team will join OpenAI’s Codex organization and reiterates a commitment to continue maintaining Astral’s open‑source projects after the acquisition closes. (astral.sh) OpenAI’s company post states Codex has experienced 3x user growth and a 5x increase in usage since the start of 2026 and now exceeds 2 million weekly active users, framing Astral’s tools as candidates to be integrated into Codex workflows. (openai.com) Neither company disclosed a purchase price in the public filings or press coverage, and Bloomberg notes the deal’s financial terms were not released. (bloomberg.com)
