Monsanto Lawsuit and Bayer Lawsuit Tracker: Every Case, Where It Stands
Questions about this case?
AI Legal Assistant · free · answers in seconds · general information, not legal advice
As of September 30, 2026, “the Monsanto lawsuit” is really several cases. The one with money attached is the proposed $7.25 billion Roundup class settlement: a St. Louis judge heard it on September 14 and has not granted final approval, so registration is closed and nothing has been paid. On September 29 a Missouri jury began hearing a Roundup trial that could help show which cancer claims survive the Supreme Court's June ruling. Separately, Monsanto's old PCB chemicals keep producing school-injury lawsuits and state cleanup settlements — neither of which has a claim form for the public.

Why Monsanto Is in the News Right Now
Two things happened fifteen days apart. On September 14, 2026, Judge Timothy Boyer of the Missouri Circuit Court in St. Louis held the fairness hearing on the Roundup class settlement, heard supporters and opponents, and reserved his decision. Monsanto's lawyer told him: “This is the settlement. There is not another settlement.” Then on September 29, according to Reuters, attorneys for three cancer patients told a Missouri jury that Monsanto failed to adequately test Roundup before selling it — a trial that could help determine which Roundup lawsuits remain viable.
Why that trial matters: in Monsanto Co. v. Durnell, the U.S. Supreme Court held on June 25, 2026 that federal pesticide law preempts a failure-to-warn claim built on Roundup's EPA-approved label lacking a cancer warning. The decision focused on warning-label claims and left other product-liability theories to be litigated. The lawsuits allege that Roundup exposure caused non-Hodgkin lymphoma; Bayer maintains that Roundup and glyphosate do not cause cancer. Monsanto has been a Bayer company since 2018, which is why the same cases are searched as a “Bayer lawsuit.”
Case Details
Roundup class settlement — King v. Monsanto Company, Case No. 2622-CC00325, Missouri Circuit Court, Twenty-Second Judicial Circuit (City of St. Louis), Division 8, Judge Timothy Boyer. Filed February 17, 2026; preliminarily approved March 4, 2026; fairness hearing held September 14, 2026; final approval not granted as of September 30. On August 27 the Eighth Circuit dismissed objectors' attempt to challenge the federal ruling that sent the case back to state court.
Supreme Court — Monsanto Company v. Durnell, No. 24-1068, argued April 27, 2026, decided June 25, 2026: 7–2, judgment reversed and remanded, opinion by Justice Kavanaugh, dissent by Justice Jackson joined by Justice Gorsuch. It came up from the Missouri Court of Appeals, Eastern District.
Federal Roundup MDL — the consolidated federal cases in California before U.S. District Judge Vince Chhabria, still more than 4,000 cases according to the law firm Miller & Zois. Most of the roughly 65,000 pending Roundup claims are in state courts.
PCB cases — injury suits in Washington state courts over the Sky Valley Education Center school, state attorney-general suits over polluted waters, and a Missouri federal case in which Monsanto sought indemnification from companies that bought its PCBs; per Mealey's, that claim was dismissed with leave to amend (reported September 25, 2026).
Essure — Bayer's permanent birth-control implant. Bayer agreed in 2020 to pay $1.6 billion to settle Essure lawsuits; Law Commentary counted almost 39,000 claims.
Status: Roundup Deal Proposed, Not Approved — Nothing Payable Yet
Roundup individual lawsuits: continuing. Bayer faces about 65,000 Roundup claims in state and federal courts, and Monsanto told the judge it is prepared to keep fighting individual lawsuits if the settlement is rejected. The Missouri trial that opened September 29 is being watched as a test of the claims that remain after Durnell.
PCBs: no consumer settlement. PCB money so far goes to states for cleanup or to individual people who sued. There is no PCB claim form for the public.

Are You Covered? It Depends on the Case
Roundup class settlement. The class covers people exposed to Roundup or other covered weed killers in the U.S. before February 17, 2026 — both people already diagnosed with non-Hodgkin lymphoma and people who have not been diagnosed. The deadline to opt out or object was June 4, 2026 and has passed. If you fit the definition and did not opt out, you are in the class; there is nothing to file until the court grants final approval. According to Miller & Zois, people who opted out can still revoke that choice until final approval — a question for your own lawyer, not for someone who calls you. People who opted out keep the right to sue on their own; state filing deadlines are on our Roundup statute of limitations page.
PCB cases. Only people who filed their own suits are parties — for example teachers, students and parents from the Sky Valley Education Center in Monroe, Washington, where the suits blame PCBs in fluorescent light fixtures. State PCB settlements are paid to states, not to residents.
What Money Exists — and Who It Is For
Earlier Roundup deals. Bayer committed roughly $10 billion in 2020; per Miller & Zois, it says it has resolved well over 100,000 claims for roughly $11 billion.
PCBs. Michigan settled for $108 million and Rhode Island for at least $25 million (up to $62.5 million, depending on Monsanto's indemnity litigation) in May 2026; Rhode Island's money goes to cleaning up contaminated waters. Juries awarded Sky Valley plaintiffs $185 million (three teachers, restored by the Washington Supreme Court on October 30, 2025) and $857 million (seven former students and parent volunteers, 2023, which Monsanto said it would seek to have reduced or overturned).
Monsanto and Bayer Litigation Timeline
- 1
2018 — Bayer Buys Monsanto
Bayer acquires Monsanto for $63 billion, and with it the Roundup and PCB litigation. Monsanto had stopped making PCBs in 1977; the U.S. banned them in 1979.
- 2
October 30, 2025 — PCB Verdict Restored
The Washington Supreme Court restores a $185 million verdict for three Sky Valley teachers. Bayer calls the ruling wrong and unconstitutional; in August it had reached confidential agreements in principle on all but eight of the other school cases.
- 3
February 17 to March 4, 2026 — Roundup Class Deal
The up-to-$7.25 billion class settlement is filed in St. Louis as King v. Monsanto and preliminarily approved on March 4.
- 4
May 18, 2026 — Two More State PCB Deals
Michigan ($108 million) and Rhode Island (at least $25 million) settle PCB pollution claims. Bayer calls them its 11th and 12th state settlements, with five state cases still pending.
- 5
June 25, 2026 — Supreme Court Rules in Durnell
By 7–2 the Court sides with Monsanto: federal pesticide law preempts the label-based failure-to-warn claim. The opt-out deadline had closed three weeks earlier, on June 4.
- 6
September 14 and 29, 2026 — Hearing, Then Trial
Judge Boyer hears the fairness arguments and reserves his decision. On September 29 a Missouri jury begins hearing three cancer patients' Roundup claims.
Three Things to Watch For
Tens of thousands of claimants, a billion-dollar number in every headline and no open claim form is the gap imposters fill:
“Register for your Roundup payment now”
Registration is not open. The court-authorized site, run by BrownGreer, says claims cannot be submitted until the court grants final approval. A page asking for your Social Security number or a “processing fee” today is not the settlement — check anything against the official site.
“Guaranteed” Roundup cases after Durnell
The Supreme Court held the label-based warning claim preempted on June 25, 2026, and trials like the one a Missouri jury began hearing on September 29 are testing what is left. Anyone quoting $165,000 as what you will get, or promising a case the ruling cannot touch, is selling certainty nobody has.
“Monsanto PCB settlement” checks
The PCB settlements pay states for cleanup, and the Sky Valley awards belong to the people who sued. There is no public PCB claims program — a letter or text offering you a share for a fee does not come from a court administrator.
Monsanto and Bayer Lawsuits — Questions People Actually Ask
What is the Monsanto lawsuit in the news right now?
Two Roundup events: Judge Timothy Boyer's pending decision on the $7.25 billion class settlement after the September 14, 2026 hearing, and a Missouri jury trial that opened September 29 over three cancer patients' claims. The PCB cases are a separate track.
Is there a Bayer lawsuit I can join?
Not by signing up. If you were exposed to Roundup in the U.S. before February 17, 2026 and did not opt out by June 4, 2026, you are already in the proposed Roundup class; claims open only after final approval. People with a diagnosis who opted out can pursue their own case with a lawyer. There is no consumer class for PCBs.
Has the $7.25 billion Roundup settlement been approved?
Not as of September 30, 2026. It has preliminary approval from March 4, 2026. Judge Boyer reserved his decision at the September 14 hearing, and the official site still says registration is not available. Our final-approval tracker follows each step.
What did the Supreme Court decide in Monsanto v. Durnell?
On June 25, 2026, by 7–2, the Court held that federal pesticide law preempts a Missouri failure-to-warn claim based on Roundup's EPA-approved label lacking a cancer warning, and reversed and remanded the Missouri judgment. Other product-liability theories were left to be litigated. Our Roundup lawsuit update covers the ruling in depth.
I opted out before June 4 — can I change my mind?
Possibly. According to Miller & Zois, people who opted out can revoke that decision until final approval, and the court's August 6 order noted “a significant number of challenges” to opt-out requests. Ask your own lawyer. Nobody can opt out for the first time now.
What is the PCB lawsuit against Monsanto?
Monsanto made PCBs until 1977. States sue over polluted waters — Bayer counted twelve state settlements and five pending state cases in May 2026 — and more than 200 teachers, students and family members sued over PCB exposure at the Sky Valley Education Center in Washington. None of it has a claim form for the public.
How much could a Roundup claim pay?
The official site says $6,000 to $165,000+, depending on exposure, age and diagnosis, paid from a program that runs for as many as 21 years. Those are gross amounts. Our per-person page breaks down the tiers.
What is worth doing right now?
Keep your pathology report, treatment records and any proof of Roundup use — receipts, job records, photos. Sign up for updates only on the official settlement site. For settlements that are taking claims today, see open class action settlements.
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.
