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 generating 25 TB of daily Earth imagery to build "large earth models" that combine planetary sensing with LLMs for searchable, time-stamped physical-world data. The company is moving toward orbital AI compute clusters, arguing that once launch costs hit $200-300/kg, placing GPUs in space becomes cheaper than terrestrial data centers due to continuous solar power and no water/building costs. China's GLM 5.2 open-weight model now matches or exceeds Western frontier models on reasoning benchmarks, showing that distillation plus efficient token use is closing the gap and making frontier intelligence impossible to contain.

Planet is a $10 billion public company (ticker: PL) with a 450% stock price increase over the past year. The company operates 200 satellites in Earth orbit, generating 25 terabytes of imagery daily. Will Marshall, co-founder and CEO, coined the term large earth models.
Large earth models work by indexing the Earth to make it searchable, similar to how Google indexed the internet. The goal is to enable humanity to become smart stewards of the planet by combining planetary sensing data with large language models.
"Bit like Google index the internet to make it searchable. We're indexing the earth to make it searchable. It will finally enable us to be smart stewards of our planet."
When discussing competition with SpaceX's plans for orbital AI data centers, Marshall noted that everyone except SpaceX pays the SpaceX launch tax, while everyone except Nvidia and Google pays the Nvidia tax. Near-term, launch costs are the dominant constraint, but longer-term, compute becomes the more important factor.
GLM 5.2 is a Chinese model that in some cases matches or exceeds top models from OpenAI and Anthropic. This level of performance in an open-weight model is considered shocking. The Chinese have figured out how to burn tokens to get more intelligence and how to reason more efficiently and cheaply.
Will Marshall is a physicist with a PhD from Oxford who previously worked at NASA. He co-founded Planet with partners after launching PhoneSat, a project that drew Steve Jurvetson's attention and led to major investment. Planet has contracts with every European government and billion-dollar-plus deals across the continent.
