Cowboy Space Raises $275 Million to Build Rockets for Space Data Centers

The Critical Rocket Shortage for Space Data Centers

The apparently insatiable demand for AI compute has data center entrepreneurs looking to the stars. However, there's a key bottleneck: There aren't enough rockets to put data centers in orbit around the Earth, and they're too expensive. Most industry players are banking on SpaceX's Starship or Blue Origin's New Glenn, but these solutions may not be commercially available for years.

Cowboy Space's Bold Rocket Development Strategy

Baiju Bhatt, CEO and founder of Cowboy Space Corporation, has announced a different approach: "We're standing up our own rocket program." He expects the first launch before the end of 2028. The company, originally launched in 2024 as Aetherflux with plans to collect solar energy in space, has pivoted to focus on space data centers, which led to the development of its own rocket program and a new name.

$275 Million Funding at $2 Billion Valuation

Today, Cowboy Space announced the closure of a $275 million Series B round at a post-money valuation of $2 billion, led by Index Ventures. Breakthrough Energy Ventures, Construct Capital, IVP, and SAIC also participated. This substantial funding will serve as a downpayment on the company's ambitious rocket development program aimed at solving the launch capacity crisis for space data centers.

Industry Transformation Through Vertical Integration

Cowboy Space's decision to develop its own rockets represents a significant shift in the space industry. While bringing rocket development in-house is logical, it's also extremely challenging—only a handful of private companies in the West, mainly SpaceX, Rocket Lab and Arianespace, are consistently launching commercial rockets. By building its rockets specifically for data center deployment, Cowboy Space enters direct competition with industry giants SpaceX and Blue Origin while addressing a critical bottleneck in the AI compute supply chain.

The Future of Orbital Data Centers by 2030

Cowboy Space plans to build its data centers directly into the second stage of its rockets, a design approach reminiscent of the first US satellite, Explorer 1. Each satellite is expected to have a mass of 20,000 to 25,000 kilograms and generate 1 MW of power for nearly 800 onboard GPUs. The company's rocket would be slightly more powerful than SpaceX's Falcon 9 but smaller than its Starship. With industry veterans from Blue Origin and SpaceX on board, Cowboy Space aims to have its first operational system ready before the end of 2028, potentially revolutionizing how AI compute is delivered in the coming decade.
