- Anthropic generated over $2.5 billion in annualized revenue from its Claude Code product, representing roughly 20 % of the company’s business as of February.
- OpenAI’s Codex was bringing in just over $1 billion in annualized revenue by the end of January, less than half Anthropic’s.
- OpenAI shifted focus after ChatGPT’s 2022 launch, reassigning the original Codex team to DALL‑E 2 and GPT‑4 development, leaving no dedicated coding product team for years.
- Anthropic trained Claude Sonnet 3.5 on messy real‑world code repositories and released Claude Code, which quickly attracted startups like Cursor and outperformed Codex in coding tasks.
- OpenAI built a reasoning model o1 that excels at generating and debugging code, then released o3 in early 2025, a model optimized for coding and the foundation for a new product.
- OpenAI formed a “sprint team” in March 2025 to combine internal groups and ship a competitive AI coding product within weeks, aiming to catch up with Anthropic’s market lead.
- Sam Altman said coding agents could become a multitrillion‑dollar market and the most likely path to artificial general intelligence, underscoring OpenAI’s urgency to launch a competitive product.
Why it matters: Enterprises that rely on AI‑assisted development stand to gain a new, faster coding assistant, while OpenAI risks losing market share and revenue to Anthropic’s faster‑to‑market Claude Code. The race also underscores how quickly product focus shifts can translate into multi‑billion‑dollar revenue gaps.
