Luma AI Funding: Rounds, Investors and Valuation
Luma AI develops generative video and multimodal AI products. Its November 19, 2025 announcement disclosed a $900 million Series C led by HUMAIN, with significant AMD participation. The Series B and C announcements reviewed here do not disclose a company valuation. This is a funding-topic guide, not a complete Luma product or rolling-news archive.
November 19, 2025 round: $900M Series C. Valuation in the reviewed Series B and C announcements: not disclosed. Project Halo: compute infrastructure, not another funding round.
Luma AI funding timeline
Luma’s own announcements provide two clear financing checkpoints. The wording matters because the Series B page reports a cumulative total, while the Series C page reports the new round amount.
Andreessen Horowitz joined the investor group. Luma thanked Amplify, Matrix, NVIDIA, South Park Commons, and angels, and said the financing would accelerate compute, data, and team growth.
HUMAIN led the round with significant AMD participation. Luma also named Andreessen Horowitz, Omniva, Amplify Partners, and Matrix Partners.

Investor roles in the Series C
Where Luma said the capital would go
Luma tied the Series C to three operating priorities: expanding research and engineering, growing the team, and scaling deployment of multimodal models. The company described its aim as building systems that jointly learn from text, video, audio, and images and can understand and simulate the physical world.
- Research and engineering: advance multimodal and world-model capabilities.
- People: expand a team that Luma said had grown beyond 130 researchers, engineers, designers, artists, and operators.
- Deployment: scale training and inference so the models can serve creative and enterprise workflows.
Valuation: what is known and unknown
Known: the Series C amount, date, lead investor, named participants, and stated use of proceeds. Unknown from Luma’s announcement: pre-money valuation, post-money valuation, ownership sold, and pricing per share.
Third-party databases may publish valuation estimates, but those numbers should be labeled by source and date. They should not be inserted into the official timeline as if Luma disclosed them.
