Musk v. Altman week 2: OpenAI fires back, and Shivon Zilis reveals that Musk tried to poach Sam Altman

Musk vs. Altman Escalates: OpenAI Countersues and Shivon Zilis Exposes Recruitment Bid for Sam Altman

The bitter feud between Elon Musk and OpenAI cofounder Sam Altman intensified this week, marking the second chapter in a high-stakes legal showdown that has captivated the AI industry. OpenAI fired back with a blistering response, accusing Musk of hypocrisy and anticompetitive tactics, while Neuralink executive Shivon Zilis publicly revealed that Musk had attempted to poach Altman just months earlier. These developments underscore deepening tensions over OpenAI’s transformation from a nonprofit research lab into a for-profit powerhouse, a shift Musk has long decried.

To recap the origins, Musk helped establish OpenAI in 2015 as a counterweight to profit-driven AI development. He pledged $1 billion but contributed only a fraction before departing in 2018 amid disagreements over control and direction. OpenAI restructured in 2019, capping investors’ returns to fund its mission while pursuing commercial viability. Musk sued in March 2024, alleging breach of contract and demanding OpenAI revert to nonprofit status and open-source its technology. OpenAI dismissed the suit as “incoherent” and “frivolous,” but a California judge allowed key claims to proceed while dismissing others.

Week one of this coverage saw Musk amend his complaint, adding racketeering charges and claiming OpenAI’s Microsoft partnership stifles competition. OpenAI moved to dismiss again, but the real fireworks erupted this week. On May 6, OpenAI filed a countersuit in San Francisco Superior Court, portraying Musk as a sore loser bent on sabotaging its success. The 35-page filing details Musk’s alleged efforts to undermine OpenAI since his exit: launching xAI in 2023 as a rival, criticizing OpenAI publicly, and now weaponizing litigation to extract value.

Central to OpenAI’s narrative is Musk’s duplicity. The countersuit alleges Musk proposed a $97.4 billion buyout of OpenAI in February 2025, far exceeding its valuation, only after his bid failed did he escalate attacks. OpenAI lawyers argue this pattern reveals Musk’s true motive: control, not altruism. “Musk’s campaign of harassment has no basis in reality,” the filing states, citing his simultaneous pursuit of massive funding for xAI, including a recent $6 billion raise valuing it at $24 billion.

Compounding the drama, Shivon Zilis, a Neuralink director and mother of three of Musk’s children, took to X on May 7 to corroborate OpenAI’s claims. Zilis, who served on OpenAI’s board until 2023, disclosed that Musk personally solicited Altman last November to join xAI. “Elon called Sam directly and tried to recruit him to xAI,” she wrote, attaching screenshots of related communications. Zilis emphasized her independence, stating she remains committed to OpenAI’s mission despite her ties to Musk’s ventures. Her revelation bolsters OpenAI’s assertion that Musk seeks to hoard top talent while decrying their for-profit pivot.

Musk responded swiftly on X, dismissing Zilis’s account as “fiction” and accusing Altman of misleading the public. He reiterated his lawsuit’s core grievance: OpenAI’s secrecy around models like GPT-4o, which he claims prioritizes profits over safety. Musk’s xAI, by contrast, open-sourced its Grok-1 model in March 2024, positioning itself as the transparent alternative. Yet OpenAI counters that Musk’s openness is selective; xAI withholds critical training data and infrastructure details.

Legal experts predict a protracted battle. OpenAI’s countersuit seeks dismissal of Musk’s claims plus sanctions for bad-faith litigation. Musk’s team, led by Marc Toberoff, vows to press forward, potentially into discovery where internal emails could expose more. The case, Musk v. OpenAI, is set for case management in June 2026 before Judge Trina Thompson.

Beyond the courtroom, implications ripple across AI. OpenAI’s $157 billion valuation, fueled by ChatGPT’s dominance, draws regulatory scrutiny from the FTC and EU. Musk’s suit amplifies calls for nonprofit AI governance, echoing concerns from figures like Geoffrey Hinton. Meanwhile, xAI’s Colossus supercomputer, powered by 100,000 Nvidia GPUs, signals Musk’s aggressive scaling.

Altman, characteristically measured, posted on X: “We remain focused on our mission to ensure AGI benefits all of humanity.” OpenAI’s board, including Zilis until recently, has weathered internal upheavals, including Altman’s brief 2023 ouster and reinstatement.

This week two clash highlights AI’s philosophical divide: open collaboration versus competitive edge. As Musk and Altman, once allies, now adversaries, battle for supremacy, the industry watches closely. The outcome could reshape governance, funding, and innovation in the race toward artificial general intelligence.
