Not Starlink. Not Starship. Not Grok. $561 Million of SpaceX's $4.4 Billion Profit Came From an Unexpected Source.

SpaceX reported $4.4 billion in Q3 2026 net income, but $561 million came from an unrealized gain on its Boring Company investment rather than core operations. While operating income improved to $2.8 billion, the company is spending $48.1 billion in capex through nine months versus only $13.1 billion in operating cash flow, creating a $35 billion deficit. Investors should focus on operating income and free cash flow rather than headline profits to assess long-term sustainability.
