SpaceX’s latest tender offer pegs its value at $350 billion. To justify that figure, analysts point beyond Starlink and launch services to a more speculative venture: orbital data centers. The concept leverages the company’s structural advantages—cheap, frequent launches via Starship and experience manufacturing satellites at scale—to address terrestrial data centers' core constraints: power scarcity and cooling costs.

The engineering trade-offs are severe. A single AI server rack can draw 100 kilowatts; current Starlink satellites generate about 3. While space provides a cold sink, heat rejection in a vacuum requires massive radiator systems, an unsolved problem at this power scale. Latency from signal propagation also rules out real-time applications, limiting initial use to batch AI training or specific government workloads, like processing reconnaissance data before downlink.

For practitioners, the architecture questions are paramount. Could you build a satellite bus that supports high-density compute, manages immense thermal loads through radiation, and powers it all with solar arrays an order of magnitude larger than today's? SpaceX’s platform offers a unique path to test this, but the leap from communication to computation in orbit is a fundamental redesign, not an incremental upgrade. The valuation reflects a bet that this engineering hurdle can be cleared, creating a new market. If it can’t, SpaceX’s established businesses remain, but the premium priced into that $350 billion would evaporate.
