📊 Thinking Machines Lab Raises $2B at $12B Valuation, Signaling Strong Backing for Murati’s Vision

Mira Murati capitalizes on her track record at OpenAI, where she oversaw ChatGPT, DALL‑E, and briefly served as interim CEO. She’s also known for her ability to recruit top talent like John Schulman and Barret Zoph. Thinking Machines is positioning itself as a creator of safe, multimodal AI—systems that can “see,” “hear,” and collaborate in human-like ways—filling a niche between experimental AGI research and industry-ready models.

While Murati’s strategy remains largely under wraps, this funding round reflects both the Power Law dynamics of venture capital and the emerging idea of a “Big Tech put.” Investors are betting that even if the company falters, its team of AI veterans is likely to be acquired or its intellectual property absorbed.

Top Takeaways

1. At $12B, this is among the largest single-stage valuations for a seed-stage startup—especially without a product or revenue track record.

2. The focus on open-source release hints at a hybrid research/commercial model aimed at both academia and startups.

3. Captured nearly 66% OpenAI alumni talent, underscoring a sharp talent exodus and realignment in generative AI.

4. AI dominated U.S. startup funding in the first half of 2025 (64% of $162.8B in deals).

5. Risks include murky roadmap, fierce competition from incumbents like OpenAI, Anthropic, DeepMind, and heavy R&D burn.

Looking Forward

Thinking Machines Lab’s debut funding is a landmark signal in AI: investors are putting big money behind proven executives and teams before the first line of code ships. With an open-source angle, heavyweights onboard, and a mission to build multimodal, collaborative intelligence, Murati’s venture is evolving beyond talent-driven hype—it’s positioning itself as a potential cornerstone lab in next-gen AI. The coming launches and early benchmarks will determine whether this ambitious wager pays off—or fuels another arms‑race acquisition.
