OpenAI M&A Spree: Seven 2026 Acquisitions Already Match Full 2025 Count — Hiro Finance Latest

Crunchbase News·medium signal

Crunchbase data shows OpenAI has made seven known acquisitions in 2026, nearly matching its full 2025 deal count, with the most recent being AI personal finance startup Hiro Finance (acqui-hired April 13, $1B+ in client assets managed in 5 months). OpenAI is systematically acquiring vertical AI startups to embed domain expertise into ChatGPT — personal finance (Hiro, Roi), developer tools (Astral, PromptFoo), and more. The pattern: rather than competing with vertical SaaS through horizontal capabilities, OpenAI is buying finished vertical products and folding them into the platform — the ultimate SaaS cannibalization strategy.
