Tomasz Tunguz, general partner at early-stage VC firm Theory Ventures, said the partnership allows SpaceX and Cursor to fill their individual infrastructure gaps.
“Winning in agentic coding requires three layers: compute, models, & distribution,” Tunguz said in an X post on Wednesday. “Anthropic, OpenAI, & Google own the full stack. xAI & Cursor each have gaps,”
He said xAI has massive compute power, referencing Musk’s Colossus data center in Memphis, but the company is losing popularity. Cursor, he said, has the opposite problem.
“Millions of developers vibe coding, but its model layer depends on OpenAI, Google, & Anthropic — all competitors. This relationship also pressures margins,” Tunguz said. “For $10 billion, SpaceX buys a call option on the distribution it couldn’t retain, & Cursor wins the independence it hasn’t yet secured.”
