Stock Market Lawsuits: Settlements, AI-Washing & SEC Rulings

Stock market lawsuits in 2026 are fewer in number but far larger in dollars than in recent years, with record per-case losses alleged, billion-dollar settlements being paid out, and a sharp rise in cases accusing companies of exaggerating artificial intelligence capabilities or hiding tariff exposure. If you held shares in a company during a period when executives allegedly misled investors, you may already be part of a pending class action without having to do anything.

How Big the 2026 Picture Looks

Federal courts saw 207 new securities class actions filed in 2025, down about 8% from 226 the year before. The money at stake went the other way. Aggregate disclosure dollar loss, which measures how much market value disappeared around the events alleged in each suit, hit $694 billion in 2025, the highest figure ever recorded. The median case alleged $503 million in disclosure dollar loss, up from $410 million the year before.¹

Settlements followed the same pattern. Seventy-nine cases resolved in 2025 for a combined $2.9 billion, with a median settlement of $17 million, a ten-year high.² Dismissals jumped 32% to 139 cases, with courts taking a median of 1.6 years to toss suits that failed at the motion-to-dismiss stage. Cases that survive and settle take a median of about 3.3 years.³

The pace of large settlements has accelerated into 2026. In the first quarter alone, 41 new class action settlements totaled $2.4 billion, with six individual cases exceeding $100 million. That is triple the number of nine-figure settlements seen in the first quarter of 2025.⁴

The Biggest Settlements Paid in 2026

Didi Global: $740 Million

The largest securities settlement of the year resolved claims that Chinese ride-hailing company Didi Global concealed cybersecurity compliance problems before its June 2021 IPO. Chinese regulators cracked down on the company shortly after it went public, and the share price collapsed. The class period was narrow, covering June 30 through July 21, 2021. Affected investors could receive an estimated $1.84 per American Depositary Share, though plaintiffs’ experts put maximum recoverable damages at about $4.56 per share.⁵ Judge Lewis A. Kaplan of the Southern District of New York granted final approval on June 16, 2026.⁶

Rivian Automotive: $250 Million

Electric vehicle maker Rivian settled claims that it made false and misleading statements in its IPO documents and a 2021 earnings report by concealing inevitable price increases around its November 2021 public offering. The $250 million deal combined $67 million from insurance and $183 million from company cash. Judge Josephine L. Staton granted final approval on May 20, 2026. Class counsel received $60 million in fees plus $6.46 million in costs.⁷ Rivian denied wrongdoing and said the settlement would let it focus on launching its mass-market R2 vehicle.⁸

Other Nine-Figure Resolutions

Celgene Corporation settled for $239 million, Fidelity National Information Services for $210 million, and Acadia Healthcare for $179 million.⁴ Plaintiffs’ firm Robbins Geller Rudman & Dowd finalized a $434 million settlement against Under Armour and a $100 million deal involving Wells Fargo oversight failures.⁹ During the same first quarter, $1.48 billion in prior settlements was actually distributed to shareholders, led by a $490 million payout from Apple’s settlement and a $200 million distribution from the Uber Technologies case.

What Companies Are Being Sued Over Right Now

AI Hype and “AI-Washing”

If one thread runs through 2026 securities litigation, it is artificial intelligence. Plaintiffs are accusing companies of exaggerating AI capabilities, overstating the efficiency gains AI delivers, or rebranding older technology as AI to attract investor enthusiasm. There were 15 AI-related securities filings in 2024 and 12 in just the first half of 2025, and the pace has continued into 2026.¹⁰

Courts are still drawing the line between corporate optimism and fraud. One judge found that calling an AI model a “fairly magical thing” was too vague to be actionable, while another ruled that touting a “significant advantage” over traditional credit-scoring models was specific enough for investors to rely on.¹⁰

The most closely watched AI suit targets Microsoft. The complaint covers May 2025 through January 2026 and alleges that CEO Satya Nadella and other executives painted a misleading picture of the Copilot AI product family. According to the complaint, the company claimed “best-in-class” capabilities and record adoption while concealing user-experience problems, data-siloing issues, and the need to divert billions in computing capacity away from the profitable Azure cloud business to keep Copilot competitive. The suit also alleges Copilot was losing ground to Google’s Gemini and OpenAI’s ChatGPT. The lead plaintiff deadline is August 11, 2026.¹¹

A February 2026 complaint against Richtech Robotics shows the AI-washing pattern in sharper relief. The Nevada company announced a collaborative partnership with Microsoft on agentic AI development, sending its stock up more than 44% in a single day. A media report the next day revealed that Microsoft denied any formal partnership, describing the arrangement as a standard customer program open to any partner. Richtech’s stock fell 20.87%, then dropped another 10.9% the following day. Plaintiffs allege the announcement was timed to inflate the stock price ahead of a $38.7 million private placement.¹²

The long-running case against enterprise AI company C3.ai is also moving forward. In March 2026, a federal judge in California partially granted and partially denied the defendants’ motion to dismiss, allowing claims that the company misled investors about its partnership with Baker Hughes and overstated its addressable market and technology investments to proceed into discovery.¹³ A putative class action against Oddity Tech alleges the beauty-tech company overstated its AI capabilities and the degree to which AI drove its sales, with a ruling on the motion to dismiss still pending.¹⁴

Tariff Exposure

The trade policy volatility of 2025 and 2026 has opened a new front. Companies that reassured investors they could manage tariff pressures and then couldn’t are now being sued over it.

Lakeland Industries was hit with a complaint in February 2026 alleging it promoted subsidiary growth for two years without disclosing tariff-related financial headwinds. When the company pulled its 2026 guidance, citing tariffs, freight costs, and supply-chain inflation, shares plunged from $23 to $9.16. Pinterest faces a similar suit filed in March 2026, alleging the social media company assured investors it could handle margin pressure on advertisers from tariffs, then slashed revenue guidance and disclosed what it called an “exogenous shock” from tariffs, sending shares down nearly 17%.¹⁵

Other Major Ongoing Cases

The securities fraud class action against Boeing, stemming from the January 2024 mid-flight detachment of a door plug from a 737, is pending before the Fourth Circuit after a district court certified the class. Investors allege Boeing made false statements about its commitment to safety over the three years leading up to the incident, artificially propping up its stock price.¹⁴

Roblox was hit with a securities class action in June 2026 covering a class period from October 30, 2025 through April 30, 2026. Plaintiffs allege the gaming platform concealed a looming slowdown in growth rates as enrollment in its age-verification rollout tapered, contributing to reduced app-store ratings and declining organic engagement. The lead plaintiff deadline is August 7, 2026.¹⁶

Stellantis faces multiple suits. A complaint filed in April 2026 covers February 2025 through February 2026 and alleges that executives guided investors toward earnings benchmarks the company had no ability to meet, while blaming a suspension of financial guidance solely on tariff-related uncertainty rather than deeper structural problems. When Stellantis disclosed €22 billion in charges on February 6, 2026, shares fell roughly 23.7% in a single day.¹⁷

A class action alleging Disney misled investors about Disney+ subscriber targets has survived multiple dismissal attempts. In August 2025, CEO Bob Iger was reinstated as a defendant. The case is moving toward trial and discovery.⁹

Court Rulings That Change the Rules

Supreme Court Expands SEC Clawback Power

On June 4, 2026, the Supreme Court ruled unanimously in Sripetch v. SEC that the agency can order wrongdoers to give back their illegal profits without first proving any investor suffered a specific financial loss. The case involved Ongkaruck Sripetch, who ran pump-and-dump schemes across at least 20 penny-stock companies. When the SEC sought over $4.1 million in disgorgement, Sripetch argued the agency had to show investors actually lost money.¹⁸

Writing for the Court, Justice Neil Gorsuch rejected that argument, holding that under traditional equitable principles, disgorgement targets the wrongdoer’s gain and not the victim’s loss. The ruling resolved a split between federal appeals courts: the First and Ninth Circuits had allowed disgorgement without proof of loss, while the Second Circuit had required it.¹⁹ Justice Clarence Thomas concurred but noted that in 2024 the SEC ordered $6.1 billion in disgorgements and returned only $345 million to victims, a disparity he suggested looks more like a fines system than restitution, which could entitle defendants to jury trials under the Seventh Amendment in future cases.¹⁸

A Pending RICO Case Could Reshape Who Can Sue

Plaintiffs who lack standing to sue under federal securities laws, such as shareholders who held stock through a fraud but never bought or sold, have increasingly tried to bring their claims under the Racketeer Influenced and Corrupt Organizations Act, which carries the prospect of triple damages and avoids the heightened pleading requirements of the Private Securities Litigation Reform Act. The Supreme Court is considering a petition in Citigroup Inc. v. Otto Candies, LLC (Docket No. 25-391) that asks whether the PSLRA bars such RICO workarounds. The First, Second, and Ninth Circuits have blocked the maneuver; the Eleventh Circuit allowed it.²⁰

Mandatory Arbitration Is Back on the Table

A long-standing SEC policy had effectively blocked companies from forcing shareholders to arbitrate disputes rather than litigate them. In September 2025, the agency reversed course and declared it would take a neutral stance on mandatory arbitration provisions. So far only one company, the small Texas-based oil explorer Zion Oil & Gas, has adopted such a provision, amending its bylaws on December 1, 2025. Legal scholars have noted that mainstream companies are staying away due to uncertainty about enforceability, the risk of triggering mass individual arbitration filings from plaintiffs’ firms, and concerns about alienating shareholders. Whether courts will uphold these clauses when challenged remains an open question.²¹

What This Means If You Owned the Stock

If you purchased shares of a company during the relevant class period, you are generally included in a securities class action automatically. There is no requirement to take affirmative action to join. Participation is the default, though you can opt out if you prefer to pursue individual claims.²²

The lead plaintiff role goes to the investor or group with the largest financial interest in the case, appointed by the court within 60 days of the first complaint. The lead plaintiff directs the litigation alongside class counsel and approves major decisions, including any settlement. If your losses are smaller, your rights are still represented by whoever is appointed, and you receive your share of any recovery automatically after the case resolves. When a settlement or judgment is reached, a claims administrator mails notice and claim forms to class members, who submit proof of their transactions, typically brokerage statements or trade confirmations, to receive payment. You do not need to still own the stock to be eligible. What matters is that you bought or sold during the class period.³

Dozens of cases have upcoming lead plaintiff deadlines in mid-2026, including suits against Microsoft (August 11), Roblox (August 7), Zoetis (July 27), Lucid Group (July 28), and Stellantis. If you held any of these stocks, you can monitor case developments through the firms representing each class or through the SEC’s investor education portal.²³
