The Monsanto Roundup lawsuit changed shape in 2026: a 7-2 Supreme Court ruling for Bayer on June 25, a $7.25 billion class settlement that Judge Timothy Boyer heard on September 14 and had not approved as of September 30, 2026, and tens of thousands of cases still open — one of which went to trial before a Missouri jury on September 29. Here is the verified status - and the science on how much exposure is dangerous.

Bayer Roundup Settlement News Today - the State of Play
Supreme Court: In Monsanto Co. v. Durnell (No. 24-1068), argued April 27 and decided June 25, 2026, 7-2 (Justice Kavanaugh writing; Justices Jackson and Gorsuch dissenting), the Court held that FIFRA preempts state failure-to-warn claims premised on a cancer warning the EPA has specifically determined is not required. The Court reversed the judgment of the Missouri Court of Appeals and remanded the case (“Judgment REVERSED and case REMANDED,” per the Supreme Court docket) and, in Bayer's words, should “significantly contain” the litigation - while legal analysts note non-label-based claims may survive. On September 29, 2026, attorneys for three cancer patients told a Missouri jury that Monsanto failed to adequately test Roundup before selling it, according to Reuters — a trial that could help determine which Roundup lawsuits remain viable after the ruling.
$7.25 billion class settlement: announced February 17, 2026, preliminarily approved by a Missouri state court on March 4, 2026; the opt-out deadline passed June 4, 2026; payouts are reported at $6,000-$165,000 per claimant by exposure, diagnosis and age, spread over up to 21 years; the fairness hearing was held on September 14, 2026 before Judge Timothy Boyer in St. Louis, who heard supporters and opponents of the deal and reserved his decision (Law Commentary); as of September 30, 2026, the official settlement site still says the court “has not yet granted final approval.” Objectors challenge the Missouri court's authority to approve a nationwide class and the $675 million in attorneys' fees sought; according to the law firm Miller & Zois, 135 objectors were heard, and people who opted out can still revoke that decision until final approval. The federal MDL judge, Vince Chhabria, has publicly questioned whether a state-court class deal can bind future claimants nationwide - the outcome is genuinely open.
Case Details
Scale: the federal MDL 2741 (N.D. Cal.) listed about 3,900 active cases in August 2026; trackers put total open cases (federal + state) at roughly 60,000-65,000 (industry estimates). As of September 2026, Law Commentary reports that Bayer faces about 65,000 Roundup claims in state and federal courts, the law firm Miller & Zois counts more than 4,000 cases still in the federal MDL, and Bayer says it has resolved well over 100,000 Roundup claims for roughly $11 billion (as quoted by Miller & Zois). Bayer raised its litigation provisions to about €11.8 billion in its 2026 half-year reporting.

How Much Exposure to Roundup Is Dangerous? What the Science Says
There is no official “dangerous dose” - the science is a dispute about risk at high exposure:
• IARC (WHO), March 2015: glyphosate classified Group 2A, “probably carcinogenic to humans” - limited human evidence (mainly non-Hodgkin lymphoma), sufficient animal evidence
• U.S. EPA: “not likely to be carcinogenic to humans” - the position the Supreme Court relied on in Durnell; EFSA and JMPR reached similar conclusions
• Zhang et al. 2019 (Mutation Research): meta-analysis found a 41% increased NHL risk in the highest-exposure groups (meta-RR 1.41, 95% CI 1.13-1.75)
• Agricultural Health Study 2018 (JNCI): the largest applicator cohort found no significant association overall - the tension between AHS and Zhang is the core of the expert fight
Law firms translate “high exposure” into intake rules of thumb - regular use over years (some cite 50+ lifetime hours or 3+ years), occupational or residential, with an NHL diagnosis at least a couple of years after first use. Those are screening criteria, not legal standards.

June 25, 2026 — Supreme Court Rules for Bayer
Durnell, 7-2: FIFRA preempts label-based failure-to-warn claims contrary to EPA's determination. The class deal's fairness hearing followed on September 14, 2026; Judge Boyer reserved his decision, and a new Roundup trial opened before a Missouri jury on September 29.
Watch Out For
The settlement window is attracting noise. Three cautions:
'Guaranteed $165,000' pitches
$165,000 is the reported top of a tiered range; most claimants fall far lower, payments stretch over years, and as of September 30, 2026, final approval had not been granted.
Pretending Durnell didn't happen
A June 2026 Supreme Court ruling narrowed the main legal theory. Any firm promising easy money without addressing preemption is behind the news.

Roundup Lawsuit - FAQ (September 2026)
What is the latest Bayer Roundup settlement news today?
As of September 30, 2026: the Supreme Court ruled for Bayer on June 25, 2026 (Durnell, 7-2); Judge Timothy Boyer held the fairness hearing on the $7.25B class settlement - preliminarily approved March 4 - on September 14 and reserved his decision, and the official settlement site still says final approval has not been granted; and on September 29 a Missouri jury began hearing three cancer patients' Roundup claims in a trial that could help show which cases survive Durnell. Judge Chhabria has voiced doubts about binding future claimants.
Is the Monsanto Roundup lawsuit over?
No. Bayer faced about 65,000 Roundup claims in state and federal courts as of September 2026 (Law Commentary), the MDL continued discovery as of July, and a new trial opened before a Missouri jury on September 29, 2026. But Durnell removed the core failure-to-warn theory where EPA said no cancer warning was required, so the landscape has shifted sharply toward settlement and narrower claims.
How much exposure to Roundup is dangerous?
Science gives no threshold. IARC calls glyphosate 'probably carcinogenic'; the EPA says 'not likely'; Zhang 2019 found 41% higher NHL risk at the highest exposures while the 2018 Agricultural Health Study found no overall link. Firms screen for regular use over years plus an NHL diagnosis.
What proof do you need for a Roundup lawsuit?
An NHL diagnosis with pathology and treatment records, proof of exposure (receipts, containers, photos, employer/job records, witnesses), and documentation of damages. Firms provide the experts; you provide the paper trail.
How much will the $7.25B settlement pay per person?
Reported range $6,000-$165,000 depending on exposure (occupational vs residential), cancer type/severity and age, paid over up to 21 years - if the court grants final approval.
I missed the June 4, 2026 opt-out deadline - what now?
If you are in the class, you remain bound by the settlement if approved and can claim under it. If you have a pending individual case, talk to your lawyer about how the class terms and Durnell affect it.
Does the $2 billion Georgia verdict mean I could get that?
No. Barnes is under appeal, Bayer notes final awards have been cut ~90% on average in concluded cases, and post-Durnell the main legal theory is narrower. Verdicts are outliers; settlement tiers are the realistic frame.
Separate from this case: were you injured in the last 2 years?
Class-action payouts are fixed amounts through an administrator. A personal injury claim is a different case — and often worth far more. Free estimate, no obligation.
