Roundup Lawsuit Eligibility: Who Can Still File After the 2026 Supreme Court Ruling
Thousands of people have sued Bayer, which bought Monsanto, claiming that exposure to glyphosate in Roundup weed killer contributed to non-Hodgkin lymphoma. The International Agency for Research on Cancer (IARC) classifies glyphosate as probably carcinogenic to humans, while the EPA has taken a different view. In June 2026 the U.S. Supreme Court limited one major theory in these cases, so eligibility questions matter more than ever. Legal Lawsuit explains what still applies and offers a Roundup lawsuit payout estimator and a free review.
Roundup Settlements and the Supreme Court Decision
Bayer has already paid billions of dollars to resolve Roundup claims and is pursuing a proposed nationwide class settlement, reported at about $7.25 billion, that received preliminary approval in a Missouri court. On June 25, 2026, the Supreme Court ruled 7-2 in Monsanto v. Durnell that federal pesticide law (FIFRA) preempts state failure-to-warn claims based on an EPA-approved label without a cancer warning. The ruling did not decide whether glyphosate causes cancer, and claims based on other theories, such as design defect or fraudulent concealment, may still proceed. Individual values vary widely and are not guaranteed.
Who Is Eligible for a Roundup Claim?
- You used Roundup regularly over a meaningful period, at home, on a farm or in landscaping work
- You were diagnosed with non-Hodgkin lymphoma, including B-cell subtypes, or a related blood cancer such as CLL
- Your diagnosis came after documented Roundup exposure
- You are within your state’s filing deadline, which is often two to three years from diagnosis or discovery, and you are not already bound by a class settlement
Heavy occupational users such as farmworkers, groundskeepers, golf course staff, landscapers and nursery workers often have the strongest exposure evidence, but regular residential users have brought claims as well.
The Science Behind Roundup Claims
Plaintiffs point to several kinds of evidence:
- IARC (2015): Classified glyphosate as “probably carcinogenic to humans” (Group 2A)
- Epidemiology: Some studies of agricultural workers have reported associations between heavy glyphosate use and non-Hodgkin lymphoma, though findings are mixed
- Company records: Plaintiffs have used internal Monsanto documents at trial to argue the company downplayed cancer concerns
- Expert testimony: Oncologists and toxicologists have testified for both sides about whether glyphosate can cause NHL
What the Litigation Looks Like Now
New Roundup claims continue to be filed, but the June 2026 Supreme Court ruling narrowed failure-to-warn theories, and the proposed class settlement affects many people who did not opt out. Whether you can still bring an individual claim depends on your exposure, diagnosis, deadline, class status and the legal theories available in your state, so get a review promptly.

Roundup Lawsuit Questions
Which cancer is linked to Roundup in these lawsuits?
Mainly non-Hodgkin lymphoma, including diffuse large B-cell, follicular and mantle cell lymphoma. Some claims involve CLL and other blood cancers. The type and severity of the cancer affect claim value.
How much is a Roundup lawsuit worth?
It depends on the cancer’s severity, how long and how heavily you were exposed, medical costs, your age, the strength of the evidence and whether your claim falls under the class settlement. Cases involving intensive chemotherapy or stem cell transplants tend to have the highest values. Our Roundup payout estimator can give an educational starting point.
Is it too late to file a Roundup claim?
Not necessarily, but deadlines, the class settlement and the Supreme Court ruling all affect who can still sue. Most states allow two to three years from diagnosis or discovery. Have an attorney check your situation before assuming either way.
What do plaintiffs claim Monsanto knew?
Plaintiffs argue that internal documents show Monsanto worked to influence research and downplay cancer concerns while marketing Roundup as safe. Bayer disputes these claims and maintains that glyphosate does not cause cancer. Juries in several trials have accepted parts of the plaintiffs’ arguments, and some awards were later reduced on appeal.
