Roundup Weedkiller (Glyphosate) Non-Hodgkin's Lymphoma Mass Tort – Bayer AG Ongoing Litigation
Case Overview
The Roundup glyphosate litigation is one of the largest and most consequential mass torts in American legal history. Since the International Agency for Research on Cancer (IARC) classified glyphosate — the active ingredient in Roundup — as 'probably carcinogenic to humans' in 2015, hundreds of thousands of plaintiffs have alleged that long-term Roundup exposure caused them to develop non-Hodgkin's lymphoma (NHL). When Bayer AG acquired Monsanto in 2018 for $63 billion, it inherited enormous legal liability: within two years, juries in California had returned verdicts of $289 million, $80 million, and $2 billion against Monsanto. In 2020, Bayer announced a landmark $10.9 billion settlement resolving approximately 125,000 cases, one of the largest product liability settlements in history.
Despite that settlement, new Roundup lawsuits continue to be filed at a rapid pace through 2025, with an estimated 60,000+ cases still active. Bayer has set aside additional billions in reserves and continues to fight certain cases at trial, recording mixed results. In 2024 and 2025, courts have issued conflicting rulings on federal preemption — specifically, whether EPA's determination that glyphosate is 'not likely carcinogenic' shields Bayer from state-law failure-to-warn claims. The U.S. Supreme Court declined to hear Bayer's preemption appeal in 2024, keeping the litigation alive and ensuring that Roundup cases will remain a defining mass tort well into the latter half of this decade.
Who May Qualify
Individuals who used Roundup or other glyphosate-containing herbicide products regularly (typically for one year or more) and were subsequently diagnosed with non-Hodgkin's lymphoma or a related blood cancer such as diffuse large B-cell lymphoma, follicular lymphoma, or chronic lymphocytic leukemia.
Frequently Asked Questions
Can I still file a Roundup lawsuit in 2025?
Yes — despite the prior $10.9 billion settlement, new Roundup cases are still being accepted. If you or a loved one developed non-Hodgkin's lymphoma after regular exposure to Roundup, you may still have a viable claim. Contact a mass tort attorney promptly, as statutes of limitations apply.
How much is a Roundup lawsuit worth?
Roundup settlements and verdicts have varied widely, from tens of thousands to millions of dollars depending on the severity of illness, length of exposure, and other factors. Bayer's 2020 settlement averaged roughly $160,000 per resolved claim, but individual trial verdicts have reached hundreds of millions.
Did the EPA say Roundup is safe?
The EPA has maintained that glyphosate is 'not likely to be carcinogenic to humans' at typical exposure levels, but the IARC (a WHO agency) classifies it as 'probably carcinogenic.' Courts have largely allowed state failure-to-warn claims to proceed despite the EPA's position, and the Supreme Court declined to grant Bayer preemption protection in 2024.
