Pinterest Lawsuit: Securities Fraud, Privacy, and Patents

A Pinterest lawsuit filed in early 2026 accuses the company and two top executives of misleading investors about how U.S. tariffs would hit its advertising revenue, and it is the most significant matter currently pending against the social media platform. It joins a newer data privacy suit and an unresolved patent case on Pinterest’s active docket. Earlier legal battles have already been resolved, including a $22.5 million gender discrimination settlement with a former COO, a $50 million shareholder derivative settlement that overhauled the company’s workplace policies, a dismissed 2021 securities class action, and a January 2026 copyright ruling in Pinterest’s favor.

The 2026 Securities Fraud Class Action

Investors filed Uziel v. Pinterest, Inc. (Case No. 3:26-cv-02745) in the U.S. District Court for the Northern District of California in early 2026.1Newsfilecorp. Pinterest Inc (PINS) Class Action Lawsuit: Investors Face May 29, 2026 Deadline The complaint names Pinterest along with CEO William Ready and CFO Julia Brau Donnelly. The proposed class covers anyone who bought Pinterest shares between February 7, 2025, and February 12, 2026, and the lead plaintiff deadline was May 29, 2026.2Levi & Korsinsky LLP. Pinterest Class Action Lawsuit (PINS)

According to the complaint, Pinterest executives described the business as “resilient, durable, and well-positioned” while concealing that advertisers, particularly large retailers exposed to U.S. tariffs, were pulling back spending. The suit alleges the revenue impact was severe enough to force a corporate restructuring that eventually included cutting nearly 15% of the workforce.2Levi & Korsinsky LLP. Pinterest Class Action Lawsuit (PINS)

The complaint also includes insider trading allegations. It claims Ready and Donnelly sold a combined 421,903 shares for over $13.5 million while the stock price was allegedly inflated. Ready sold roughly 141,000 shares for over $4.3 million, and Donnelly sold roughly 281,000 shares for over $9.1 million.2Levi & Korsinsky LLP. Pinterest Class Action Lawsuit (PINS)

The triggering event was Pinterest’s fourth-quarter 2025 earnings report on February 12, 2026. Ready attributed the shortfall to “an exogenous shock this year related to tariffs,” and Donnelly said the headwinds on large retailers “created a more meaningful headwind than we expected” and could become “slightly more pronounced” in the first quarter.3CNBC. Pinterest (PINS) Q4 Earnings Report The next day, Pinterest shares fell roughly 17% to close at $15.42, and at least 16 brokerages cut their price targets.4Investing.com. Pinterest Stock: Tariff Shock Exposes Retail Ad Dependence The complaint also points to earlier declines: a roughly 20% drop on November 4, 2025, after third-quarter results, and another after Pinterest announced workforce and office cuts on January 27, 2026.

The case is in its early stages. As of mid-2026, no lead plaintiff has been appointed.

The Brougher Gender Discrimination Settlement

In August 2020, former Chief Operating Officer Françoise Brougher sued Pinterest in San Francisco County Superior Court, alleging she was fired after reporting sexist comments by then-CFO Todd Morgenfeld and objecting to compensation less favorable than her male peers received. She also alleged exclusion from important meetings before and after Pinterest’s IPO.5Cohen Milstein. In Re Pinterest Derivative Litigation

Pinterest settled in December 2020 for $22.5 million without admitting liability. As part of the deal, Pinterest and Brougher jointly donated $2.5 million to charities supporting women and underrepresented minorities in tech.6The New York Times. Pinterest Gender Discrimination Lawsuit

The Brougher case followed public allegations by former public policy employees Ifeoma Ozoma and Aerica Shimizu Banks, both of whom said they were underpaid and assigned lower internal levels than white colleagues doing comparable work, costing them stock options worth hundreds of thousands of dollars. Both resigned in May 2020 and filed complaints with California’s Department of Fair Employment and Housing.7The Washington Post. Pinterest Race Bias: Black Employees

The $50 Million Shareholder Derivative Settlement

The discrimination allegations also produced a shareholder action. On November 30, 2020, the Employees’ Retirement System of Rhode Island filed In re Pinterest Derivative Litigation (Case No. 3:20-cv-08331-WHA) in the Northern District of California against Pinterest officers and directors, including co-founder Ben Silbermann, co-founder Evan Sharp, and Morgenfeld. The shareholders alleged the board breached its fiduciary duties by facilitating or ignoring a “systematic culture, policy, and practice of illegal discrimination” dating back to at least 2018.5Cohen Milstein. In Re Pinterest Derivative Litigation

Judge William Alsup granted final approval on June 9, 2022. Rather than a cash payout to shareholders, the settlement required Pinterest to spend $50 million on workplace and governance reforms.5Cohen Milstein. In Re Pinterest Derivative Litigation The key terms included releasing former employees from non-disclosure agreements so they could speak about mistreatment, bi-annual external pay equity audits covering compensation, promotions, and performance ratings across gender and racial categories, Audit Committee oversight of equity reforms, a board member designated to co-sponsor diversity efforts with the CEO, and diversity progress reports to shareholders.8Cohen Milstein.

The Dismissed 2021 Securities Class Action

The 2026 tariff case is not Pinterest’s first securities fight. A 2021 class action (Case No. 20-cv-08243) in the Northern District of California covered the period from February 4 through April 27, 2021, and alleged Pinterest concealed slowing user growth and an expected engagement decline in the second quarter of 2021. Shares dropped roughly 14.5% after the company reported that global monthly active user growth had slowed from 37% to 30% year-over-year. Judge William H. Orrick granted the defendants’ motion to dismiss on September 23, 2021.9Kessler Topaz Meltzer & Check LLP. Pinterest Inc Securities Fraud Class Action

The 2026 Data Privacy Suit

On February 20, 2026, California resident Ken Zhu filed Zhu v. Pinterest Inc. (Case No. 3:26-cv-01529) in the Northern District of California. The complaint alleges Pinterest embedded a “Pinterest Tag” and other tracking tools on third-party websites to capture users’ email addresses, IP addresses, and browsing activity from at least 35 websites without consent, and used the data to build marketing profiles for targeted advertising. The complaint invokes federal and state privacy laws.10Bloomberg Law. Pinterest Sued Over Consumer Data Tracking on Third-Party Sites The case is in its early stages.

The Harrington Copyright Ruling

In January 2026, a federal judge in the Northern District of California granted Pinterest summary judgment in Harrington v. Pinterest, a case brought by the estate of photographer Blaine Harrington III.11PetaPixel. Court Sides With Pinterest in Copyright Case Brought by Photographer Over Push Notifications

At issue was whether Pinterest’s email and push notifications, which displayed thumbnails of user-uploaded images including one of Harrington’s photographs of Waikiki Beach, fell outside the Digital Millennium Copyright Act’s safe harbor. The estate argued the safe harbor did not reach images sent by email or push notification. The court disagreed, finding “little difference between an infringing display via web browser… and an infringing display via email” because both simply provide access to content stored on Pinterest’s servers at user direction. The court also found no evidence Pinterest had actual knowledge of the infringement or drew a direct financial benefit from it, noting that general advertising revenue and platform growth were not enough to meet that standard.12IPWatchdog.

The OpenTV Patent Suit

In December 2024, OpenTV, Inc., a subsidiary of the Kudelski Group, filed a patent infringement lawsuit against Pinterest in the U.S. District Court for the District of Delaware. The suit alleges Pinterest infringes four U.S. patents covering core platform features, including the delivery of video pins, marketing funnel functionality, and targeted advertising.13NAGRA.
