SpaceX Spent $18.4 Billion in a Single Quarter -- $15.8 Billion of It on AI. Here's Where the Money Is Going.

Space Exploration Technologies Corp. (SpaceX) deployed $18.4 billion in capital expenditures during the second quarter of 2026, with $15.8 billion—approximately 86% of the total—directed toward its artificial intelligence division, SpaceXAI. In comparison, Starlink received $1.4 billion and rocket operations accounted for $1.2 billion. The aggressive capital deployment was concentrated in compute infrastructure, expanding SpaceXAI's compute power capacity from 1.0 gigawatt in Q1 to 1.4 gigawatts in Q2 2026. The investment drove substantial top-line momentum, with SpaceXAI's quarterly revenue nearly tripling from $818 million to $2.56 billion quarter-over-quarter. Compute demand is further underpinned by a commercial contract with Anthropic, expected to generate up to $1.25 billion per month once full capacity is operational. SpaceX's capital allocation mirrors an expansive buildout across tech giants, where hyperscalers Meta, Amazon, Microsoft, and Alphabet collectively spent $302.8 billion on capex during the first half of 2026.
