The $10B Satellite Empire Putting AI in Orbit, Why Chips Beat Rockets & China's #1 Open Model | #266
In a Nutshell
Planet operates a 200-satellite constellation imaging the entire Earth daily, turning that data into "large Earth models" that give LLMs real-world sensor grounding for applications from farming to defense. Its long-term bet is orbital AI data centers—placing GPUs next to sensors in space—where the decisive constraint will shift from launch costs to compute efficiency (inference per watt), favoring Google TPUs over Nvidia GPUs. Meanwhile, China's open-weight GLM 5.2 model has closed the frontier gap, proving advanced reasoning intelligence can no longer be monopolized and forcing urgent global decisions on AI governance and alignment.

Planet is a $10 billion public company with ticker PL. The company operates 200 satellites in Earth orbit, generating 25 terabytes of imagery every day. Will Marshall, CEO and co-founder, coined the term large earth models. The concept is analogous to how Google indexed the internet to make it searchable. Planet is indexing the Earth to make it searchable, enabling smarter stewardship of the planet.
When asked about competing with Elon Musk's plans for orbital AI data centers, Marshall noted that everyone except SpaceX pays the SpaceX launch tax, and everyone except Nvidia and Google pays the Nvidia tax. Near-term, the launch tax is more important, but longer-term, compute is the more significant constraint.
A Chinese model called GLM 5.2 in some cases matches or exceeds top models from OpenAI and Anthropic. The level of performance in an open-weight model is described as shocking. The Chinese have figured out how to burn tokens to get more intelligence and are figuring out how to reason more efficiently or cheaply.
Will Marshall is a physicist who earned his PhD at Oxford. Before founding Planet, he worked at NASA. He co-founded Planet with Robbie Schingler and partners. The company started by launching PhoneSat, a phone into orbit. Steve Jurvetson became a major investor. Planet has seen a 450% increase in stock price over the last year.
