❯ SemiAnalysis Says SpaceX to Build ~10GW of Compute by End of 2027, Microsoft Is Largest Buyer

10GWSemiconductor research firm SemiAnalysis released a report concluding that SpaceX could have ~10GW of compute built by end of 2027, with 6–8GW of that landing in 2027 alone; the report’s headline annualized revenue figure is $500 billion, while the body separately lays out a path to roughly $300 billion in annualized revenue by end of 2027. The report names Microsoft as the largest compute buyer, saying it has already signed binding contracts for 10GW this year.

PRICING PREMISEWhether this math holds hinges entirely on pricing: SemiAnalysis says large-scale, near-term-deliverable compute can sell for up to $50 billion per GW per year. Musk previously said on an earnings call that cumulative capacity brought online by end of 2027 would be “closer to 10GW than 5GW.” At that unit price, the annualized revenue range for 10GW at full utilization lands squarely between the $300 billion and $500 billion cited in the report — meaning the denominator of the entire projection is price, not capacity.

HARD WALLThere’s a hard wall on the supply side. Researcher @zephyr_z9 has calculated: 10GW requires roughly 3 million Rubin GPUs, while Nvidia’s total 2027 capacity is about 10 million units — SpaceX alone would consume over 30%. Whether that ratio holds directly determines the queue order for all other buyers — and how much of this revenue table still holds water.
