World model maker Odyssey nabs $1.45B valuation backed by Amazon and other big names

What happened

World-model startup Odyssey (CEO Oliver Cameron, ex-Voyage) announced on June 17, 2026 a $310M Series B at a $1.45B post-money valuation. Natural Capital led, with Amazon, AMD Ventures, GV, EQT and IQT joining.

Context and impact

World models are seen as the next wave after LLMs — modeling physical reality with accurate physics for robotics, simulation, and synthetic data generation. Odyssey collects data Google-Earth-style, with people walking around carrying back-mounted cameras. The round signals Amazon stacking against Nvidia (via Trainium + AWS preferred cloud) and building its own world-model stack.
