AI Summary
5 min readSpaceX and Cursor team up to topple Claude Code
SpaceX and Cursor are partnering to build what they call "the world's best coding and knowledge work AI." The deal, which broke on April 22, 2026, is structured as a collaboration with an acquisition option: SpaceX will pay Cursor $10 billion for the joint model work, with the option to buy Cursor outright for $60 billion by the end of 2026. Given that Cursor is currently raising at a $50 billion valuation and will likely be worth more by year-end, the $60 billion buyout represents a discount — effectively a call option on the company.
Why the deal makes sense for both sides
Cursor has become one of the few credible competitors to OpenAI's Codex and Anthropic's Claude Code. It reached $2 billion in annualized run rate earlier this year and recently released Composer 2, its own model that benchmarks competitively against GPT-5.4 and Opus 4.6. Critically, Cursor also has deep developer market share, which means it collects real-world usage data from users who opt in — a training advantage that pure model companies lack.

Today’s show:
This week, SpaceX announced that it was partnering with AI coding startup Cursor on new AI models. xAI’s parent company is bringing compute, while Cursor brings developer market share and recent successes, training its own coding models.
The deal, while interesting, comes with a steep price tag. SpaceX will pay Cursor $10 billion for their shared work, with an option to buy the entire company for $60 billion later this year.
After poking our way through the deal, Chris Zacharia and Brian McRindle of Bitstarter joined Lon and Alex. Bitstarter is a ‘Kickstarter for Bittensor,’ helping founders get their subnet up and running without tripping over their shoelaces. The Bitstarter crew also broke some news on the show, telling TWIST that they have a new accelerator-ish program kicking off.
Next, Ning Ren from Trajectory RL joined the program to explain how Bittensor subnet 11 is using decentralized competitions to design and release better skills. Skills — markdown files with words — have become a critical building tool in the agentic era; how Trajectory will monetize is an open, interesting question.
