Bill Savitt Elon Musk lawyer matchups have become one of the most consistent storylines in Silicon Valley litigation over the past four years, and the record speaks for itself: twice now, Wachtell, Lipton, Rosen & Katz litigator William Savitt has gone head to head with the world’s richest man in court, and twice he has won decisively. First in 2022, when he forced Musk to honor his $44 billion agreement to buy Twitter. Then in May 2026, when he led OpenAI’s defense and convinced a federal jury to reject Musk’s $150 billion lawsuit against Sam Altman in less than two hours of deliberation. The pattern is striking enough that it has become a defining feature of Savitt’s career, and a recurring source of public frustration for Musk himself.
Round One: Forcing the Twitter Deal in 2022
The first major confrontation between Savitt and Musk began when Musk tried to walk away from his agreement to buy the social media company outright.
In 2022, Savitt led Wachtell, Lipton, Rosen & Katz to represent Twitter, now X, in its contract dispute with Elon Musk, who had sought to withdraw from the $44 billion acquisition. During pretrial, Savitt argued that Musk’s attempt to exit the deal lacked a legal basis and countered Musk’s request to delay the trial as a strategy to avoid fulfilling the agreement. He also highlighted how Twitter complied in providing Musk’s team with substantial data access, countering Musk’s claims for more information as a pretext for exiting the deal. CompareNI
“Bill Savitt, Twitter’s top lawyer on the case, claimed Musk was ‘banking on’ a justice ‘delay’ becoming ‘justice denied,'” while Musk’s lawyer fixated on Twitter’s calculations of spam accounts, arguing once again the company refused to offer Musk adequate data on bots and fake accounts. Musk is a ‘liar looking to conjure an exit ramp for a deal that doesn’t have one,’ Savitt said. Insurance Business America
The uncertainty caused by Musk’s threat to pull out of the deal “inflicts harm on Twitter every hour of every day,” Bill Savitt said at the hearing. Savitt accused Musk of trying to “sabotage” the deal and run out the clock past the deadline when the $13 billion Musk had lined up from banks to fund the deal would expire. Settle
The Delaware Court of Chancery, under Chancellor Kathaleen McCormick, granted an expedited hearing for an October 2022 trial. Musk eventually agreed to proceed with the acquisition on its original terms. CompareNI
That outcome forced Musk into one of the most expensive and consequential corporate purchases of his career, a deal he had publicly tried to escape, and Savitt’s litigation strategy was widely credited as the decisive factor that left Musk with no viable exit.
Round Two: Crushing the OpenAI Lawsuit in 2026
Four years later, Savitt and Musk met again, this time with Savitt on the opposite side of the table representing OpenAI against a lawsuit Musk had filed personally.
A federal court on Monday dismissed claims filed against OpenAI and its top executives by Elon Musk, who accused them of betraying a shared vision for it to remain a nonprofit dedicated to guiding artificial intelligence’s development for the good of humanity. The nine-person jury found Musk waited too long to file his lawsuit and missed a statutory deadline. After a three-week trial, the jury deliberated less than two hours. Actuarialpost
“It did not take the jury two hours to conclude that Mr. Musk’s lawsuit is nothing more than an after-the-fact contrivance that bears no relationship to reality,” OpenAI’s lead attorney, Bill Savitt, said after the verdict. “They kicked it exactly where it belongs, just to the side. This lawsuit is a hypocritical attempt to sabotage a competitor.” Consumerintelligence
“Mr Musk may have the Midas touch in some areas, but not in AI,” William Savitt, a lawyer for OpenAI, said in his closing argument. Confused.com
In his opening statement, Savitt told jurors it was Musk who saw dollar signs as he helped finance OpenAI’s early growth and pushed it to become a for-profit business, one he might eventually lead as CEO. Savitt said Musk wanted “the keys to the kingdom” and sued only after he failed, and then in 2023 started his own AI business, xAI. “What he cares about is Elon Musk being on top,” Savitt said. “We are here because Mr Musk didn’t get his way.” Quotezone
The Trial Itself: Character Attacks and a Sworn Confrontation
The three-week OpenAI trial in Oakland produced some of the most combative courtroom exchanges of Musk’s career, with Savitt at the center of the confrontation.
Musk testified late last month, and he was very combative while OpenAI’s lawyer, William Savitt, asked him questions. Musk accused Savitt of lying, asking misleading questions and questions that were designed to trick him. The pair argued back and forth on several occasions, and both men raised their voices.

Savitt, in his opening statement, said AI safety wasn’t a priority for Musk and that Musk denigrated OpenAI employees who focused on it. “Jackasses is what he called them,” Savitt said. Quotezone
Musk stopped coming to court after the first week, apparently choosing to travel to China with President Donald Trump instead, and was made to seem erratic, testy, and vindictive throughout the proceedings. CompareNI
The case ultimately centered on whether Musk’s claims were filed in time. In statements after her ruling, federal Judge Yvonne Gonzalez Rogers said there was substantial evidence that Musk knew or could have known enough about OpenAI to file his lawsuit prior to 2024. CompareNI
Musk’s Response: Defiance and an Appeal
Musk did not accept the verdict quietly, immediately signaling his intention to challenge the ruling at the appellate level.
Musk slammed the verdict, calling it a “terrible precedent.” Musk said he will appeal, repeating his claim that Altman and OpenAI President Greg Brockman viewed OpenAI as a means to great wealth. Musk said in a post on X that he will appeal the decision. “There is no question to anyone following the case in detail that Altman and Brockman did in fact enrich themselves by stealing a charity. The only question is WHEN they did it!” Confused.com
“I will be filing an appeal with the Ninth Circuit, because creating a precedent to loot charities is incredibly destructive to charitable giving in America,” Musk wrote. Reached for comment, Musk’s lead counsel, Marc Toberoff, said simply: “One word: Appeal.” Consumerintelligence
Musk’s team was led by Steve Molo of MoloLamken and Marc Toberoff of Toberoff & Associates. Altman and OpenAI were represented by a team of Wachtell Lipton and Morrison & Foerster lawyers led by William Savitt and Sarah Eddy. Moneyexpert

Latest Update: What Comes Next for Musk’s Appeal
The Bill Savitt Elon Musk lawyer rivalry now moves to its third chapter, with Musk’s appeal heading to the Ninth Circuit Court of Appeals.
The jury’s verdict was merely advisory, but Judge Gonzalez Rogers quickly accepted its conclusion as her own and dismissed the case. Musk said he plans to appeal. We’ll see what happens at the Ninth Circuit. Moneyexpert
Microsoft, which owns 27 percent of OpenAI and was a named defendant in Musk’s suit, said in an email that it “welcomed the jury’s decision to dismiss these claims as untimely.” OpenAI attorney Bill Savitt said in a statement: “We’re pleased that the jury reached the right result, and reached it quickly.” CompareNI
The appeal will likely take months to resolve and represents Musk’s final legal avenue to revive his claims against Altman, Brockman, and Microsoft.

Broader Implications: A Pattern Worth Watching
The Bill Savitt Elon Musk lawyer rivalry illustrates something larger than two individual legal victories. It speaks to the limits of even the world’s richest person’s leverage when facing a litigator who consistently outmaneuvers him on procedural and substantive grounds alike.
In the Twitter case, Savitt’s strategy denied Musk the delay tactics he sought, forcing the acquisition through on its original terms. In the OpenAI case, Savitt’s defense framed Musk’s entire lawsuit as a calculated business maneuver against a competitor rather than a genuine grievance, and the jury agreed within two hours. Both outcomes share a common thread: Savitt consistently exposed gaps between Musk’s public framing of a dispute and the legal record underpinning it.
For Musk, the pattern raises a genuine strategic question heading into the Ninth Circuit appeal and any future legal confrontations involving Wachtell Lipton’s litigation team. For Savitt, it cements a reputation as one of the few attorneys who has repeatedly and successfully gone toe to toe with one of the most litigious figures in American business.
