To completely pull ahead of its competitors in the AI programming arena, OpenAI once again waved its checkbook.

On March 19, OpenAI officially announced the acquisition of Astral, a startup that builds open-source tools for developers. After the acquisition, the Astral team will be fully integrated into OpenAI, with the core mission of injecting new research and development momentum into the AI programming assistant Codex. Although the exact acquisition amount was not disclosed, this move undoubtedly demonstrates OpenAI's determination to dominate the developer market.

Astral's founder and CEO Charlie Marsh stated in a blog post that their goal has always been: to create tools that change the experience and make programming more efficient than ever before. This aligns perfectly with OpenAI's vision of deeply embedding AI throughout the entire software development lifecycle.

The programming race has become a "close combat"

In the past year, the popularity of AI programming assistants has exploded.OpenAI is facing strong competition from multiple sides:

Anthropic: With the excellent performance of the Claude series models in code logic, it is constantly eroding the professional market.

Cursor: As a rising underdog, it has won the favor of many developers with its extremely smooth experience.

Facing the competition, Codex has shown astonishing growth. According to OpenAI, the weekly active users of Codex have exceeded 2 million, and the user base has tripled since the beginning of this year.

The Acquisition Maniac: OpenAI's Ecosystem Puzzle

Since entering 2026, OpenAI's acquisition pace has significantly accelerated, trying to quickly fill gaps through acquisitions:

Hardware layout: In May 2025, it acquired io, an AI device company founded by Jony Ive, the former Apple design chief, for 6.4 billion dollars.

Security and healthcare: Earlier this month, it acquired the cybersecurity startup Promptfoo, and in January, it also acquired the healthcare technology startup Torch.

With the joining of former Google corporate development strategy leader Albert Lee, the acquisition logic of OpenAI has become clearer: by acquiring top teams precisely, it is building a comprehensive competitive advantage in key areas such as security, healthcare, hardware, and developer tools.

As AI not only writes code but also manages code through more professional tools, the development model of programmers is undergoing a deep transformation led by OpenAI
