Tesla IncTesla gains significant revenue from SpaceX's Megapack purchases and AI compute demand, though some demand is internal.
Tesla and SpaceX are becoming increasingly intertwined across semiconductors, energy storage, AI computing and connectivity, raising questions about how much demand reflects the open market versus Musk buying from himself. Both companies are working on Terafab, an advanced semiconductor facility with an initial $16.8 billion investment, to address their growing chip requirements, with Musk indicating combined AI compute demand could exceed 1 terawatt annually. SpaceX purchased $329 million of Tesla Megapacks in the first half of 2026, following $506 million in 2025, and is targeting 20 GW of power and cooling capacity by the end of 2027, though Musk said 15 GW may be more realistic. Tesla's Digital Optimus robot is being built around SpaceX's infrastructure, Grok is being integrated into Tesla vehicles, and Starlink connectivity is being integrated into Cybercab. While disclosed pricing appears to be on market terms, investors should distinguish between Musk-driven demand and independently validated market demand.
