The old rivals are back at each other’s throats, and this time Apple’s lawsuit lit the fuse.
Elon Musk and Sam Altman reignited their years-long feud on X this weekend, just days after Apple sued OpenAI over alleged trade secret theft. The exchange turned personal fast, dragging in AI models, IPOs, and old grudges.
Key Details
Musk and Altman co-founded OpenAI back in 2015 as a nonprofit research lab. Musk exited the board in 2018 after donating tens of millions, and their relationship has been rocky ever since, including a 2026 trial where a jury sided with Altman over Musk’s claims about OpenAI’s for-profit shift. Musk says he’ll appeal.
The timing here matters. SpaceX just pulled off a $75 billion IPO, and OpenAI has quietly filed for its own. This week, both companies dropped new AI models – Grok 4.5 and GPT-5.6 Sol – and the launch hype spilled straight into an online brawl. Musk called Altman “Scam Altman” repeatedly, mocked his space data center comments, and referenced his legal troubles. Altman shot back, joking that Musk’s attention was really just proof that GPT-5.6 Sol is winning.
Market Reaction
Apple, Tesla, and SpaceX shares saw minor moves, with Tesla down about 1%, though nothing dramatic tied directly to the spat.
For traders, this isn’t just tabloid drama. AI leadership fights are shaping billion-dollar deals, IPO timing, and product rollouts across the sector – all things that move sentiment fast.
What to Watch
Keep an eye on the Apple-OpenAI lawsuit, SpaceX’s pending $60 billion Cursor acquisition, and any fallout from Musk’s own antitrust suit against Apple and OpenAI.
