Meta Platforms has completed the acqui-hire of Dreamer, the AI agent startup founded by industry veterans Hugo Barra, David Singleton, and Nicholas Jitkoff. The entire Dreamer team has joined Meta Superintelligence Labs under Chief AI Officer Alexandr Wang to accelerate the company's AI agent ambitions. Dreamer had launched earlier in 2026 with a revolutionary operating system for AI agents, enabling users to discover, build, and deploy personalized AI assistants without coding. The acquisition marks Meta's second major move in the AI agent space this March, following the Moltbook acquisition earlier in the month.

OpenAI announced on March 19, 2026, that it will acquire Astral, the company behind the widely-used open source Python developer tools uv, Ruff, and ty.

Astral's tools have achieved hundreds of millions of monthly downloads, making them foundational to modern Python development. The deal underscores OpenAI's aggressive push into the developer tools market as competition intensifies with rivals like Anthropic.

Elon Musk’s SpaceX has officially acquired/merged with xAI, consolidating Musk’s two largest private businesses into a single mega‑company that also encompasses X (formerly Twitter), which xAI previously acquired in 2025. Multiple outlets report the tie‑up values SpaceX at ~$1T and xAI at ~$250B, for a combined valuation around $1.25T. Musk and SpaceX frame the rationale around an ambitious plan to build space-based AI data centers to address power and cooling constraints on Earth—an idea he has been promoting more aggressively in recent months.
