Musk Faces Trial Over Claims He Manipulated Twitter Stock During $44B Takeover
Former Twitter shareholders allege billionaire's bot concerns were pretense to drive down share price, setting up precedent-defining test of M&A conduct.
A federal trial that began this week in San Francisco examines whether Elon Musk deliberately manipulated Twitter’s stock price during the chaotic six-month period between signing and closing his $44 billion acquisition of the social media platform in 2022.
According to Bloomberg, investors allege that Musk publicly attacked the company in a ruse to drive down its market value and benefit himself at their expense, despite eventually paying the originally agreed price of $54.20 per share. The class-action lawsuit, filed in October 2022, claims Musk made deliberately misleading statements about spam bot accounts to depress Twitter’s stock while also failing to disclose when his stake exceeded 5%, according to Courthouse News Service.
The Core Allegation: Bot Complaints as Market Manipulation
The plaintiffs—including lead investors Steve Garrett, Nancy Price, John Garrett, and Brian Belgrave—allege Musk suffered major losses when he deliberately made misleading statements about spam bots to drive down the stock in hopes of backing out or renegotiating more favorably, according to Courthouse News Service. The lawsuit hinges on whether Musk’s highly publicized concerns about fake accounts constituted legitimate due diligence or intentional Stock Manipulation.
The statements at issue include a May 13, 2022 tweet where Musk said the Twitter deal was on hold “pending details supporting calculation that spam/fake accounts do indeed represent less than 5% of users”, as reported by Courthouse News Service. According to the Fordham Journal of Corporate and Financial Law, Musk did not conduct due diligence as part of the agreement and was aware of Twitter’s fake accounts prior to signing, yet failed to negotiate contractual protections.
The Delayed Disclosure Dimension
A parallel issue compounds the shareholders’ case: According to the SEC’s complaint, Musk was able to make purchases of Twitter stock at artificially low prices from unsuspecting sellers who had not yet priced in the material information of his ownership exceeding 5%, allowing him to underpay by at least $150 million. When Musk finally disclosed his stake, Twitter’s stock price jumped 27%, based on SEC filings.
In a separate but related case, a federal judge in New York ruled in March 2025 that a proposed class-action lawsuit over the delayed disclosure could proceed, according to CNBC. In February 2026, a federal judge rejected Musk’s attempt to dismiss the SEC lawsuit, after Musk had accused the agency of selective enforcement and challenged the case as an affront to his constitutional free-speech rights, as reported by Bloomberg.
The Market Context: A Deal Gone Sour
According to Fortune, Twitter’s stock declined nearly 20% between when Musk first made the offer to buy the company in April and when he formally announced he was pulling out on July 8, fueled partly by a larger market downturn and massive selloff in tech stocks that began in May. The stock closed at $32.65 on July 11, 2022, nearly 40% below the $54.20 per share price Musk agreed to pay, as reported by The Washington Post.
According to Twitter’s disclosures to the SEC, there had been no change in the percentage of fake bots on its platform for the last eight years, with the company consistently reporting the same qualified estimate, as noted in the Fordham Journal of Corporate and Financial Law. The company acknowledged that spam/bot accounts comprised less than 5% of monetizable daily active users, a figure Twitter had published for the last three years, according to TIME.
The lawsuit filed in federal district court for Northern California argues that Musk intentionally drove down the company’s stock to secure a better deal, stating “The fair market value of Twitter securities has been adversely affected by Musk’s false statements and wrongful conduct”, according to TechCrunch.
The Legal Framework at Stake
The trial is being closely watched by M&A practitioners and securities lawyers as a potential landmark case for shareholder rights and executive conduct during acquisition negotiations. U.S. District Judge Charles R. Breyer, a Bill Clinton appointee presiding over the trial, has noted that Musk is a public figure who will excite strong views, with the question being whether jurors can set them aside, as reported by Courthouse News Service.
In December 2023, Breyer allowed the investors’ claims to advance, finding Musk made a series of statements that were false or misleading in the days following the announcement of his Twitter purchase, according to Courthouse News Service. The trial, which seated nine jurors on February 20, is expected to last around three weeks, as reported by San Francisco Today.
- Shareholders allege Musk’s bot concerns were pretextual, designed to drive down Twitter’s stock after market conditions soured on the $44 billion deal
- Musk ultimately paid the full $54.20 per share after Twitter sued to enforce the merger agreement in Delaware Chancery Court
- The case could establish precedent for what constitutes legitimate due diligence versus market manipulation in signed M&A transactions
- Separate SEC and shareholder lawsuits over Musk’s delayed disclosure of his 5% stake remain pending
What to Watch
The trial’s outcome will hinge on whether the jury believes Musk’s concerns about spam accounts were genuine due diligence—despite waiving such diligence in the original agreement—or a cynical attempt to extract concessions after Tesla’s stock price collapsed. A plaintiff victory could establish new guardrails around acquirer conduct in signed deals, while a Musk win would affirm broad latitude for buyers to raise questions about target company disclosures even after signing. The defense has not indicated whether Musk will testify, according to Courthouse News Service.
With Musk’s legal team from Quinn Emanuel representing him against a class of former Twitter shareholders, the trial represents a high-stakes test of the boundary between permissible hardball negotiating tactics and securities fraud. The verdict, expected by late March, will be scrutinized by corporate law scholars, M&A advisors, and boards considering how much post-signing flexibility exists in acquisition agreements.
