Elon Musk’s 2022 Twitter acquisition has produced a cluster of lawsuits still working through the courts. The biggest is a securities fraud class action in San Francisco, where a federal jury in March 2026 found Musk misled investors and calculated damages that plaintiffs’ lawyers estimate could reach about $2.6 billion. Alongside it sit an SEC enforcement settlement over a late stock disclosure, severance fights involving former executives and thousands of laid-off employees, a WARN Act class action, an antitrust suit X Corp filed against advertisers, and a breach of contract claim from a former board chair.
The $2.6 Billion Investor Verdict
Giuseppe Pampena v. Elon Musk, No. 3:22-cv-05937, was filed in the Northern District of California on behalf of investors who sold Twitter stock, call options, or put options between May 13 and October 4, 2022. The theory: Musk’s public statements putting the deal “on hold” and questioning Twitter’s fake-account numbers drove the share price down, so shareholders who sold during that stretch received far less than the $54.20 per share they would have received when the deal closed in October.1Courthouse News Service.

After nearly four days of deliberation, the nine-person jury delivered a split verdict on March 20, 2026. It found Musk liable for two specific tweets: the May 13, 2022 post declaring the acquisition “temporarily on hold,” and the May 17, 2022 post claiming more than 20 percent of Twitter traffic came from fake accounts and that the deal therefore “cannot move forward.” The jury rejected two other fraud claims, treating statements Musk made on a podcast as opinion, and absolved him of the broader allegation that he ran a “scheme” to intentionally defraud investors.3NPR.

How the Damages Work
Instead of a single lump sum, the jury calculated per-share damages of between $3 and $8 for each of the 98 trading days in the class period.4PBS NewsHour.

Musk’s team asked the court to set the verdict aside. At a June 18, 2026 hearing, Judge Breyer said Musk’s liability was “readily apparent” and supported by “ample evidence.”6Bloomberg Law.

The SEC Case Over the Late Disclosure
A separate track focuses on the eleven days between when Musk crossed the 5 percent Twitter ownership threshold on March 14, 2022 and when he filed the required SEC disclosure on April 4. According to the SEC’s January 14, 2025 complaint, Musk kept buying during that window, purchasing more than $500 million in additional shares between March 25 and April 1, and underpaid by at least $150 million relative to what those shares would have cost had investors known about his position.8SEC.

Severance and Layoff Litigation
Former Executives
Days after closing, Musk fired Twitter’s top leadership. Former CEO Parag Agrawal, CFO Ned Segal, chief legal officer Vijaya Gadde, and general counsel Sean Edgett sued in San Francisco federal court, claiming they were owed $128 million in severance covering one year of salary and stock awards. They alleged Musk falsely accused them of misconduct to avoid paying; Musk and X Corp maintained the firings were for performance.13CNBC.

The Rank-and-File Class Action
Twitter’s workforce shrank from roughly 7,500 to fewer than 2,000 after the acquisition.15The New York Times. Elon Musk X Settlements Former employees Courtney McMillian and Ronald Cooper filed McMillian v. X Corp. in 2023, alleging a 2019 severance plan promised most workers at least two months of base pay plus tenure-based additions, while the company paid at most one month and often nothing. The suit sought about $500 million.16CNN. Musk X Agreement Twitter Firings
A California federal judge dismissed the case in July 2024, ruling that no qualifying severance plan existed under federal benefits law. The employees appealed to the Ninth Circuit with amicus support from the U.S. Department of Labor. About a month before scheduled arguments, in August 2025, X Corp agreed to a tentative class-wide settlement on undisclosed terms. X also reached separate agreements with more than 2,000 former employees pursuing severance in arbitration, reportedly covering nearly all owed severance plus interest.17Bloomberg Law. Musk, X Corp.

The WARN Act Class Action
Filed November 3, 2022 in the Northern District of California (No. 3:22-cv-06857), this class action alleges Twitter violated the federal Worker Adjustment and Retraining Notification Act by cutting roughly 3,700 jobs, about half its workforce, without the required 60 days’ advance written notice. Attorney Shannon Liss-Riordan brought it on behalf of five named plaintiffs.18ClassAction.org. Cornet et al. v. Twitter Inc. The case was later transferred to federal court in Delaware, where a dismissal motion was pending as of mid-2025. It is one of at least eight federal WARN Act cases against the company, alongside dozens of individual suits and arbitration claims.19Bloomberg Law.

X Corp’s Antitrust Suit Against Advertisers
In August 2024, X Corp sued the World Federation of Advertisers, its Global Alliance for Responsible Media (GARM) initiative, and more than a dozen large companies including Unilever, Mars, CVS Health, Nestlé, and Lego, alleging a coordinated advertising boycott that violated federal antitrust law and cost X billions in ad revenue. GARM shut down shortly after the suit was filed.20BBC News. X Corp Advertising Boycott Lawsuit Dismissed
On March 26, 2026, U.S. District Judge Jane Boyle in Dallas dismissed the case with prejudice. She found X had not shown the kind of competitive harm antitrust law addresses, noting the defendants had not tried to corner any market and GARM neither bought ad space from X nor told X not to sell directly to advertisers. The court also found it lacked jurisdiction over several defendants and denied X the right to appeal.21The Hill. Elon Musk X Lawsuit Dismissed22The Next Web. X Advertising Boycott Lawsuit Dismissed
The Kordestani Stock Options Claim
Former Twitter executive chairman Omid Kordestani sued X Corp in San Francisco Superior Court on August 9, 2024 (No. CGC-24-617142), alleging the company refused to cash out his vested stock options and stock units after the acquisition.
