Roundup Lawsuit 2026: Glyphosate Cancer Claims Against Bayer/Monsanto
Roundup lawsuits allege that Monsanto, now owned by Bayer, failed to warn users that glyphosate, the active ingredient in Roundup weed killer, could cause non-Hodgkin lymphoma. Bayer denies the allegations. A proposed nationwide class settlement announced in February 2026 is awaiting a court ruling, and federal cases are consolidated in MDL 2741.

What the Roundup lawsuit is about
The Roundup lawsuit targets Bayer AG (which acquired Monsanto) for failing to warn users that glyphosate — the active ingredient in Roundup weed killer — causes non-Hodgkin lymphoma and other serious cancers. The International Agency for Research on Cancer (IARC) classifies glyphosate as a probable human carcinogen. If you regularly used Roundup and were diagnosed with cancer, you may be entitled to significant Roundup lawsuit compensation.

Roundup Lawsuit Settlement Amounts 2026
Bayer has paid roughly $11 billion resolving about 100,000 Roundup cancer lawsuits since 2020 — one of the largest products liability programs in U.S. history. On 17 February 2026 Monsanto announced a proposed nationwide class settlement of non-Hodgkin lymphoma claims, filed in the Circuit Court of the City of St. Louis, Missouri. Bayer describes it as “declining capped annual payments for up to 21 years totaling up to US$7.25 billion.” Bayer’s announcement does not give individual amounts, but the official settlement FAQ lists average awards by tier, from $10,000 to $165,000 depending on exposure type, age and the form of lymphoma, plus quick-pay awards of $6,000 to $14,500; an individual award can range from 80% to 120% of its tier average. The court granted preliminary approval in March 2026 and held the final approval hearing on 14 September 2026; Bayer states that “the Court’s final approval decision is expected to come at a later time and not in conjunction with the hearing.” The settlement is therefore proposed, not payable. Jury verdicts at trial have exceeded $2 billion, but large punitive awards in this litigation are routinely reduced on post-trial motions and appeal. In June 2026 the Supreme Court ruled for Bayer on federal preemption in Monsanto v. Durnell, a significant setback for state failure-to-warn claims.

Who Qualifies for a Roundup Lawsuit?
- You used Roundup weed killer regularly for at least one to two years — including residential, agricultural, and landscaping use
- You were diagnosed with non-Hodgkin lymphoma, B-cell lymphoma, chronic lymphocytic leukemia (CLL), or another blood cancer
- Your cancer diagnosis followed your documented Roundup exposure
- You filed within your state’s statute of limitations (typically 2-3 years from cancer diagnosis)
Occupational exposures — farmworkers, groundskeepers, golf course workers, landscapers, nursery workers — represent the strongest Roundup lawsuit cases due to high-volume, long-duration exposure. However, residential users who applied Roundup regularly are also filing and winning Roundup lawsuits.
The Science Behind Roundup Cancer Claims
The Roundup lawsuit is supported by robust scientific evidence:
- IARC Classification (2015): Classified glyphosate as “probably carcinogenic to humans” (Group 2A)
- AGRICOH Study: Large-scale agricultural health study found significant association between glyphosate use and non-Hodgkin lymphoma
- Internal Monsanto Documents: Trial evidence revealed that Monsanto executives knew about cancer risks for decades while publicly claiming Roundup was safe
- Expert Testimony: Leading oncologists and toxicologists have testified in Roundup trials about the causal link between glyphosate and NHL
Roundup Lawsuit Status 2026
Three developments now shape every Roundup claim. On June 25, 2026, the U.S. Supreme Court held 7–2 in Monsanto Co. v. Durnell that federal pesticide law (FIFRA) preempts a state-law failure-to-warn claim that would require a cancer warning on the Roundup label, and on June 30 it sent the Anderson, Salas and Johnson judgments back to be reconsidered in light of that ruling. The proposed class settlement of up to $7.25 billion was still awaiting final approval on October 1, 2026, after the September 14 fairness hearing, and claims cannot be filed until the court approves it. And 1,104 cases were still pending in the federal Roundup MDL (No. 2741) on October 1, 2026, according to the Judicial Panel on Multidistrict Litigation. The EPA, which concluded in 2017 that glyphosate is not likely to be carcinogenic to humans, expects to finish an updated cancer evaluation in late 2026.
Our guide to the Roundup class action lawsuit explains who the proposed settlement covers and what the Durnell ruling does and does not decide. Filing deadlines still vary by state, so anyone considering a claim should have the deadline checked promptly.
Roundup lawsuit FAQ
What cancer does Roundup cause?
The cancer most strongly linked to Roundup exposure in litigation is non-Hodgkin lymphoma (NHL), including diffuse large B-cell lymphoma, follicular lymphoma, and mantle cell lymphoma. Chronic lymphocytic leukemia (CLL) and other blood cancers have also been linked to glyphosate exposure. The specific cancer type affects the value of your Roundup lawsuit settlement.

How much is my Roundup lawsuit worth?
Individual Roundup lawsuit settlements have ranged widely based on cancer severity, Roundup exposure duration, medical expenses, age of the plaintiff, and strength of evidence. Serious NHL cases with chemotherapy, stem cell transplants, or permanent health impacts typically yield the highest Roundup settlement amounts. Use our Roundup settlement calculator for an initial estimate.

Is it too late to file a Roundup lawsuit?
New Roundup lawsuits are still being filed and accepted in 2026. However, statutes of limitations apply — typically 2-3 years from your cancer diagnosis. Do not wait to contact an attorney. If you’re unsure whether your deadline has passed, an attorney can evaluate your specific situation — many survivors are surprised to learn they still have valid Roundup claims.
Did Bayer/Monsanto know Roundup caused cancer?
Yes — internal documents revealed in litigation show that Monsanto executives knew about the cancer risks of glyphosate for decades while publicly claiming Roundup was safe. The company funded scientific studies designed to create doubt about glyphosate’s carcinogenicity and worked to discredit independent researchers who found cancer links. This systematic deception is central to Roundup lawsuits and explains why juries have awarded punitive damages against Bayer in multiple trials.
