Odyssey Raises $310M for World Models, Picks Amazon and AMD Over Nvidia
One-liner: World model startup Odyssey closed a $310M Series B at a $1.45B valuation — and conspicuously left Nvidia off the cap table while bringing in Amazon and AMD.
Key Facts
- Round led by Natural Capital; Amazon, AMD Ventures, GV, EQT, and CIA-affiliated In-Q-Tel joined
- AWS designated preferred cloud provider; Odyssey will run training and inference workloads on Amazon Trainium chips
- Nvidia's NVentures led the February 2026 Series A but did not participate in Series B
- Odyssey builds real-time physics-accurate world models targeting robotics, autonomous systems, and simulation-heavy gaming
Why It Matters
The cap table shift is a concrete data point in the ongoing battle to unseat Nvidia as the default AI chip. Odyssey is a credible lab — its Starchild-1 real-time multimodal world model and Agora-1 multi-agent framework have drawn frontier-lab attention. If Trainium proves competitive for world simulation workloads, other compute-hungry startups may follow suit.
