OpenAI Has Already Made 6 Acquisitions in 2026 — Nearly Matching All of 2025 in One Quarter

Crunchbase News·medium signal

Crunchbase data shows OpenAI completed 6 acquisitions by March 2026, including Astral (open-source developer tools, March 19) and Promptfoo (LLM evaluation), nearly matching its full 2025 M&A count in a single quarter. This acquisition velocity — combined with the ChatGPT super app consolidating chat, coding, search, and agents — signals OpenAI is building a vertically integrated platform that directly competes with multiple SaaS categories simultaneously. Every acquisition strengthens the case that foundational model companies are becoming the new platform monopolies, absorbing tools that used to be standalone SaaS businesses.
