Tesla has disclosed that it expects to pull in roughly $890 million in revenue from transactions with two other companies controlled by Elon Musk: SpaceX and xAI. The revenue spans from 2023 through early 2026, covering everything from energy storage hardware to vehicle sales.

Where the money is coming from

In 2025 alone, Tesla reported $573 million in revenue from Musk-related entities. The lion’s share, $430.1 million, came from xAI. Another $143.3 million came from SpaceX.

The xAI revenue is largely driven by sales of Tesla’s Megapack energy storage systems. SpaceX, meanwhile, has been purchasing vehicles from Tesla.
