AI rivalry Elon Musk and Sam Altman: SpaceXAI vs OpenAI battle for the AI throne

AI rivalry Elon Musk and Sam Altman heats up as SpaceXAI and OpenAI chase the next breakthrough

Elon Musk and Sam Altman have reignited their billionaire clash, each trying to convince investors that their vision will dominate the AI frontier. The feud, rooted in a 2015 partnership that birthed OpenAI, resurfaced over Apple’s recent lawsuit accusing OpenAI of misusing proprietary data.

Apple sued OpenAI and two ex‑Apple engineers on Friday, alleging theft of trade secrets to boost OpenAI’s hardware ambitions. OpenAI dismissed the claim, stating it “has no interest in other companies’ trade secrets.” Reuters reported the filing.

Musk seized the moment, tweeting, “Scam Altman strikes again.” He followed with a string of barbs, calling Altman “the king of scams” and suggesting he “loves scamming more than any human alive.”

Altman replied on X: “Musk is the one selling public‑market investors on short‑term space datacenters.”

Musk countered, “We start flying them next year. Maybe you can visit if your parole officer approves.” He also referenced a prior allegation that Altman “stole” OpenAI’s core mission.

Origins of the feud

In 2015, Musk, then CEO of Tesla and SpaceX, teamed with Altman, then head of Y Combinator, to launch OpenAI as a nonprofit aimed at preventing a single entity from monopolizing artificial intelligence. By 2018 Musk offered to inject up to ↑ $1 B and fold OpenAI into Tesla, but the board rejected the proposal. Musk quit the board and withdrew funding.

The split hardened when OpenAI released ChatGPT in 2022, catapulting it into a multi‑billion‑dollar enterprise. Musk sued the company in 2024, seeking ↓ $150 B in damages and demanding a return to nonprofit status. A May jury dismissed the case on procedural grounds; Musk has signaled an appeal.

Undeterred, Musk founded xAI in 2023, unveiled the Grok model, and later merged xAI into SpaceX, rebranding the venture as SpaceXAI. The unit went public in June, raising a record‑setting ↑ $4.5 B. OpenAI quietly filed for its own IPO the same month.

Competition flared again this week: OpenAI announced GPT‑5.6 Sol, while SpaceXAI rolled out Grok 4.5. Altman posted, “There are a lot of benchmarks that suggest 5.6 Sol is the best model in the world right now, but the most reliable way to tell is that Elon is obsessed with me again.”

Analysts at Bloomberg note that the rivalry could shape funding flows, talent migration, and regulatory scrutiny across the AI sector for years to come.
