Latest update (as of September 21, 2026): On June 25, 2026, the U.S. Supreme Court ruled 7-2 in Monsanto v. Durnell that federal pesticide law preempts state-law failure-to-warn claims when the EPA has made a definitive safety determination, a major shift in how Roundup claims are pursued.
Separately, on September 14, 2026, a St. Louis judge heard final-approval arguments on Monsanto’s proposed $7.25 billion class settlement but did not rule that day. Objectors have challenged the notice process, the opt-out terms, and a $675 million attorney-fee request. As of this check, no ruling has been reported and no class payments have been made.
Last updated: September 2026
The Roundup weed killer lawsuit is one of the largest product liability cases in U.S. history, and it is still active in 2026. If you or someone you know used Roundup and later developed non-Hodgkin’s lymphoma, you may be entitled to real money.
Bayer, the company that now owns Monsanto, has already paid out more than $10 billion across tens of thousands of claims. That number keeps growing.
This guide covers everything you need to know: who qualifies, how much you can get, what the 2026 updates mean for your case, and exactly what steps to take before the deadline closes on you.
What Is the Roundup Weed Killer Lawsuit?
The Roundup weed killer lawsuit refers to mass tort litigation filed by people who claim Roundup herbicide caused their cancer. Specifically, plaintiffs allege that glyphosate, the active chemical in Roundup, causes non-Hodgkin’s lymphoma.
These are not a single class action. They are individual personal injury claims bundled together through multidistrict litigation, known as MDL 2741, in the Northern District of California.
The lawsuits target both Monsanto, the company that made Roundup for decades, and Bayer AG, the German pharmaceutical and chemical giant that acquired Monsanto in 2018. When Bayer bought Monsanto for $63 billion, it also inherited this legal nightmare.
Quick Facts:
| Detail | Info |
|---|---|
| Lawsuit Type | Mass tort / personal injury |
| MDL Case Number | MDL 2741 |
| Court | U.S. District Court, N.D. California |
| Company Sued | Monsanto / Bayer AG |
| Core Claim | Roundup causes non-Hodgkin’s lymphoma |
| Total Claims Filed | Over 160,000 |
The central argument is simple: Monsanto knew glyphosate was potentially carcinogenic but chose not to warn users. That failure to warn is at the heart of every lawsuit.
Roundup Lawsuit 2026: Where Things Stand Right Now
In 2026, the Roundup lawsuit is still very much alive. New claims are being filed. Pending cases are moving through courts. And Bayer is still fighting certain claims while settling others.
The U.S. Supreme Court declined to hear Bayer’s appeal in 2023. That decision was a turning point. It left intact the legal framework allowing juries to award damages even when the EPA says glyphosate is not a carcinogen.
Bayer set aside $16 billion in total to address Roundup litigation. Roughly $10 billion has been paid out as of recent reporting. The remaining funds are actively allocated for pending and future claims.
2026 Status Summary:
| Status | Detail |
|---|---|
| Active Claims | Thousands still pending in state and federal courts |
| Supreme Court Appeal | Denied in 2023; no federal preemption protection for Bayer |
| Settlement Fund | $16 billion reserved; $10 billion+ paid |
| New Claims | Still being accepted in 2026 |
| Claims Closed | Some early MDL waves are fully settled |
If your diagnosis happened recently, 2026 may actually be a better window to file. Courts are more experienced with the evidence now, and payout structures are more defined.
Bayer Roundup Lawsuit: How Monsanto’s Parent Company Got Sued
Bayer AG became the defendant in the Roundup lawsuit because it acquired Monsanto in June 2018. The deal closed just weeks after a California jury handed Dewayne Johnson a $289 million verdict against Monsanto.
Bayer did not make Roundup. But it bought the company that did. When you buy a company, you inherit its liabilities.
That is the basic legal reality Bayer has been wrestling with since 2018. The company has publicly stated it believes glyphosate is safe. Courts and juries have repeatedly disagreed.
Key Bayer Litigation Milestones:
- August 2018: Bayer acquires Monsanto; litigation exposure revealed
- 2019: Edwin Hardeman wins $80 million verdict in federal court
- 2019: Pilliod couple wins $2 billion verdict (later reduced to $87 million)
- 2020: Bayer announces $10.9 billion settlement framework
- 2023: U.S. Supreme Court refuses to shield Bayer from state failure-to-warn claims
- 2026: Remaining claims proceed; new filings still accepted
Bayer’s core legal defense has been that the EPA approves glyphosate. Judges have ruled that federal EPA approval does not preempt state law failure-to-warn claims. That legal door remains open in 2026.
Key Takeaway: The Roundup lawsuit is a mass tort against Bayer AG, filed by over 160,000 people claiming Roundup’s active ingredient caused their cancer, and it remains active in 2026.
Roundup Cancer Lawsuit: What Disease Is at the Center of This?
The Roundup cancer lawsuit is centered on one specific diagnosis: non-Hodgkin’s lymphoma. This is a cancer of the lymphatic system, and it is the only cancer type consistently tied to glyphosate exposure in court-accepted science.
Non-Hodgkin’s lymphoma, often abbreviated NHL, includes over 60 subtypes. B-cell lymphomas are the most commonly cited in Roundup cases.
Think of it like an umbrella term. NHL is the umbrella. Diffuse large B-cell lymphoma, follicular lymphoma, and mantle cell lymphoma are some of the types that fall under it.
Cancer Types Accepted in Roundup Lawsuits:
| Cancer Type | Commonly Accepted |
|---|---|
| Non-Hodgkin’s Lymphoma (general) | Yes |
| Diffuse Large B-Cell Lymphoma | Yes |
| Follicular Lymphoma | Yes |
| Chronic Lymphocytic Leukemia (CLL) | In some cases |
| Multiple Myeloma | Limited; contested |
| Hodgkin’s Lymphoma | Generally not accepted |
Plaintiffs must show they used Roundup and later developed one of the accepted cancer types. The timeline of exposure and diagnosis matters to courts.
Glyphosate Lawsuit: Why One Chemical Started It All
Glyphosate is the herbicide chemical that is the center of every lawsuit filed against Roundup. It is one of the most widely used pesticides in the world, appearing in Roundup and hundreds of other products.
In 2015, the International Agency for Research on Cancer, known as IARC, classified glyphosate as “probably carcinogenic to humans.” That single report changed everything.
It gave plaintiffs the scientific foundation to argue in court that Roundup exposure is not harmless. Monsanto and Bayer have repeatedly pushed back, pointing to EPA findings that glyphosate is not a carcinogen.
The Science Divide:
| Agency | Finding on Glyphosate |
|---|---|
| IARC (2015) | Probably carcinogenic to humans (Group 2A) |
| U.S. EPA | Not likely to be carcinogenic to humans |
| California OEHHA | Listed as a known carcinogen under Prop 65 |
| European Chemicals Agency | Not classified as carcinogen |
Courts have generally allowed juries to weigh both sides. Juries have repeatedly sided with plaintiffs when the IARC classification and internal Monsanto documents are presented together.
Those internal documents showed company scientists worried about glyphosate’s safety long before the IARC ruling. That evidence has been central in the biggest verdicts.
Key Takeaway: Glyphosate’s 2015 IARC “probably carcinogenic” classification is the scientific foundation for every Roundup lawsuit, and courts have consistently let juries decide which science to believe.
Who Qualifies for the Roundup Lawsuit?
You qualify for the Roundup lawsuit if you used Roundup or a glyphosate-based herbicide and were later diagnosed with non-Hodgkin’s lymphoma or a related lymphatic cancer. Both residential and occupational users qualify.
You do not have to be a farmer. Homeowners who used Roundup in their yards have successfully filed claims and received compensation.
Occupational users, such as landscapers, groundskeepers, golf course workers, and agricultural workers, tend to have stronger claims because their exposure was more frequent and prolonged.
General Qualification Checklist:
- You used Roundup or a glyphosate product directly (sprayed it yourself)
- Your exposure occurred over multiple uses, not just once
- You were diagnosed with non-Hodgkin’s lymphoma or an accepted subtype
- Your diagnosis came after documented Roundup exposure
- You are within the statute of limitations for your state
Family members of deceased users may also file wrongful death claims. Those claims carry the same eligibility requirements but must be filed by a surviving spouse, child, or legal representative.
Roundup Lawsuit Eligibility: Full Requirements Breakdown
Roundup lawsuit eligibility depends on four core factors: product use, duration of exposure, cancer diagnosis, and timing of the claim.
Courts and claims administrators look at all four together. Meeting just one or two factors is not enough to build a strong claim.
Duration matters a lot. Studies cited in trial testimony suggest that longer and more frequent exposure correlates more strongly with cancer risk. Plaintiffs who used Roundup for two or more years tend to have the strongest cases.
Eligibility Requirements Table:
| Requirement | What Courts Look For |
|---|---|
| Product Used | Roundup or glyphosate-based herbicide |
| Exposure Duration | Ideally 2+ years or repeated use |
| Exposure Type | Direct contact (spraying, mixing, handling) |
| Cancer Diagnosis | Non-Hodgkin’s lymphoma or accepted subtype |
| Diagnosis Timing | After documented Roundup exposure |
| Filing Deadline | Within your state’s statute of limitations |
| Medical Records | Pathology report confirming cancer diagnosis |
Age and general health history can affect settlement valuation. Younger plaintiffs with more severe cancer diagnoses and longer life expectancy losses typically receive higher settlements.
Key Takeaway: To file a valid Roundup claim in 2026, you need a documented cancer diagnosis, proof of repeated Roundup exposure, and you must file before your state’s statute of limitations runs out.
Roundup Non-Hodgkin Lymphoma Lawsuit: The Cancer Connection Explained
The Roundup non-Hodgkin lymphoma lawsuit is built on the argument that glyphosate disrupts the immune system in a way that leads to abnormal lymphocyte growth. That is the biological mechanism plaintiffs’ experts have argued in court.
NHL is not one disease. It is a family of cancers originating in the white blood cells called lymphocytes. The lymphatic system runs throughout the body, which is why NHL can appear in lymph nodes, the spleen, or bone marrow.
The Dewayne Johnson case in 2018 was the first to go to trial. Johnson, a school groundskeeper, had used Roundup extensively. He was diagnosed with NHL and died shortly after the trial. The jury awarded him $289 million, later reduced to $20.4 million on appeal.
NHL Subtypes and Roundup Lawsuit Acceptance:
| NHL Subtype | Accepted in Claims |
|---|---|
| Diffuse Large B-Cell Lymphoma | Yes |
| Follicular Lymphoma | Yes |
| Mantle Cell Lymphoma | Yes |
| Marginal Zone Lymphoma | Yes |
| Burkitt Lymphoma | Sometimes accepted |
| T-Cell Lymphoma | Evaluated case by case |
If your diagnosis falls outside this list, a legal evaluation is still worthwhile. Claims administrators look at each case individually based on medical evidence presented.
Roundup Weed Killer Lawsuit Settlement: What Has Been Paid Out?
The Roundup weed killer lawsuit settlement is not one single payment. It is a collection of individual settlements, jury verdicts, and negotiated agreements worth more than $10 billion combined as of 2026.
Bayer announced a $10.9 billion settlement framework in June 2020. That covered approximately 125,000 resolved claims. Thousands more were carved out or excluded from that framework.
Some of those excluded cases went to trial and produced massive jury verdicts. The Pilliod case, for example, produced an original verdict of $2 billion in punitive damages before being reduced by the court to $87 million.
Settlement Payment History:
| Year | Event | Amount |
|---|---|---|
| 2018 | Johnson v. Monsanto verdict | $289M (reduced to $20.4M) |
| 2019 | Hardeman v. Monsanto verdict | $80.2M (reduced) |
| 2019 | Pilliod v. Monsanto verdict | $2.055B (reduced to $87M) |
| 2020 | Bayer global settlement announcement | $10.9B for ~125,000 claims |
| 2021-2022 | Additional state court settlements | Varied |
| 2023-2026 | Ongoing claims from remaining plaintiffs | Active |
The settlements do not mean Bayer admitted wrongdoing. Settlements rarely involve admissions. But they do mean people received real money.
Key Takeaway: Bayer has paid out over $10 billion in Roundup settlements, with individual verdicts ranging from $20 million to $87 million after appeals, and more payments are flowing in 2026 for unresolved claims.
Roundup Settlement Amount: How Much Is the Fund Worth?
The Roundup settlement fund totals approximately $16 billion in reserves set aside by Bayer. Of that, more than $10 billion has already been distributed to settled plaintiffs.
That leaves a meaningful portion still available for pending and future claims. Bayer has also set aside additional reserves specifically for cases that have not yet been evaluated or filed.
The fund is not a shared pool where everyone divides one number equally. Each claim is valued individually based on medical evidence, exposure history, and severity of harm.
Roundup Fund Overview:
| Category | Estimated Amount |
|---|---|
| Total Reserves Set Aside | $16 billion |
| Amount Already Paid | $10+ billion |
| Claims Resolved | ~125,000+ |
| Average Settlement Value | $150,000 to $200,000 (estimated range) |
| Remaining Available | Billions still in reserve |
Think of it like an insurance pool. The total pot is fixed. But how much you pull from it depends entirely on your specific situation. Two people with NHL from Roundup exposure could receive very different amounts.
Roundup Lawsuit Payout Per Person: What Can You Actually Expect?
The Roundup lawsuit payout per person ranges widely, from around $5,000 for minor claims to more than $250,000 for severe cases involving terminal cancer diagnoses and prolonged exposure.
Individual jury verdicts have been far higher. But most claims settle, and settled amounts are typically lower than jury verdicts, even if they are more predictable and faster to receive.
The biggest driver of your individual payout is diagnosis severity. A plaintiff who recovered fully from early-stage follicular lymphoma will receive less than one who developed an aggressive terminal form of NHL.
Payout Range Breakdown:
| Claim Severity | Estimated Payout Range |
|---|---|
| Minor exposure, mild diagnosis | $5,000 to $50,000 |
| Moderate exposure, treatable NHL | $50,000 to $150,000 |
| Significant exposure, aggressive NHL | $150,000 to $300,000 |
| Terminal diagnosis, extended exposure | $300,000 to $500,000+ |
| Jury verdict (not settled) | Millions (variable) |
These are estimates based on reported settlement ranges and verdict data. Your specific amount will depend on medical records, expert testimony, and negotiation.
Roundup Lawsuit Compensation: What Factors Change Your Award?
Roundup lawsuit compensation is calculated based on several specific factors that courts and claims administrators use to score and rank individual claims.
It is not random. The process has structure. Think of it like a point system where each factor adds or subtracts from your base compensation value.
The most impactful factors are: cancer type, stage at diagnosis, exposure frequency, age at diagnosis, economic losses, and ongoing medical costs.
Compensation Factors:
| Factor | Impact on Award |
|---|---|
| Cancer stage at diagnosis | Higher stage = higher award |
| Cancer type (aggressive vs. slow-growing) | Aggressive = higher |
| Years of Roundup use | More years = stronger claim |
| Age at diagnosis | Younger = higher loss of earnings |
| Medical treatment costs | Chemotherapy, transplants increase value |
| Lost wages and career impact | Documented losses increase award |
| Death of plaintiff | Wrongful death claims often higher |
| State law damages caps | Can reduce punitive damages in some states |
Punitive damages, the kind that punish bad corporate behavior, have been awarded in jury trials but are sometimes reduced on appeal. Most settled claims include compensatory damages only.
Key Takeaway: Your individual Roundup payout depends most heavily on cancer severity, exposure duration, and economic losses, with the strongest claims involving terminal diagnoses and multi-year occupational exposure.
How to File a Roundup Lawsuit Claim in 2026
Filing a Roundup lawsuit claim in 2026 starts with gathering your medical records and documenting your Roundup exposure history. You do not need a receipt from a hardware store. But you do need to show you actually used the product.
The process is not as complicated as people fear. Mass tort claims follow a defined path. You submit documentation. An attorney reviews it. The claim gets evaluated against eligibility criteria. Then settlement negotiations begin.
Here is the step-by-step process most claimants follow:
Filing Process:
| Step | Action Required |
|---|---|
| 1 | Gather medical records showing NHL diagnosis |
| 2 | Document Roundup exposure: years used, frequency, brand |
| 3 | Collect witness statements or co-worker testimony if available |
| 4 | Request medical records from treating oncologist |
| 5 | Submit claim through a mass tort law firm |
| 6 | Claim gets reviewed and scored by legal team |
| 7 | Settlement offer made or case goes to trial |
| 8 | Compensation paid after agreement |
You do not need purchase receipts to file. Witness testimony, photos, and employer records can substitute. Courts have accepted a wide range of exposure documentation.
Lawsuit Against Roundup Weed Killer: Key Court Cases That Changed Everything
The lawsuit against Roundup weed killer changed course in three landmark trials between 2018 and 2019. Those three cases set the legal precedent that made tens of thousands of additional claims viable.
Each case went before a jury in California. Each jury found Monsanto liable for cancer caused by Roundup exposure. Each verdict included both compensatory and punitive damages.
These are not minor cases. They are the legal bedrock of every claim filed today.
Three Landmark Roundup Trials:
| Case | Plaintiff | Verdict | Key Outcome |
|---|---|---|---|
| Johnson v. Monsanto (2018) | Dewayne Johnson | $289M (reduced to $20.4M) | First ever Roundup trial win |
| Hardeman v. Monsanto (2019) | Edwin Hardeman | $80.2M (reduced) | Federal court precedent set |
| Pilliod v. Monsanto (2019) | Alva and Alberta Pilliod | $2.055B (reduced to $87M) | Largest punitive award |
Hardeman’s case was particularly significant because it was the first federal bellwether trial in MDL 2741. Federal bellwether trials are test cases designed to see how juries respond to evidence before thousands of other cases settle.
The Ninth Circuit Court of Appeals upheld the Hardeman verdict in 2021. That ruling told Bayer that federal courts would not protect it from state failure-to-warn claims. Bayer’s hope of a Supreme Court rescue died in 2023.
Roundup Lawsuit Update 2026: The Latest Legal Developments
The Roundup lawsuit update for 2026 shows continued litigation activity with new waves of claims, ongoing state court trials, and Bayer still seeking legislative relief from Congress.
Bayer has lobbied lawmakers to pass a law that would shield pesticide makers from failure-to-warn lawsuits when the EPA approves their product. That effort has not succeeded as of 2026.
At the state court level, juries are still awarding large verdicts. California, Missouri, and Pennsylvania courts have all seen active Roundup trials in recent years. That pattern continues in 2026.
2026 Key Developments:
- Bayer’s congressional lobbying effort for federal preemption protection remains stalled
- State court trials continue producing plaintiff-friendly verdicts
- New cases are still being evaluated and accepted by mass tort firms
- Appeals from prior verdicts are still working through the system
- Bayer’s stock has taken repeated hits each time a major verdict is announced
One more important development: some courts have begun consolidating smaller claims for faster processing. That means some plaintiffs who filed later may actually see resolution sooner than those who filed years ago.
Key Takeaway: In 2026, Bayer still faces active litigation in multiple state courts, new claims are still being accepted, and the company’s attempt to get congressional protection has not moved forward.
Roundup Lawsuit Deadline 2026: When You Must Act
The Roundup lawsuit deadline varies by state because personal injury statutes of limitations differ across the country. Most states give you two to three years from the date of cancer diagnosis to file.
Missing that deadline means losing your right to sue permanently. No exceptions. No extensions. That is why the timing of your filing matters as much as the strength of your medical evidence.
Some states have a “discovery rule.” That means the clock starts not when you were diagnosed, but when you reasonably discovered that Roundup may have caused your cancer. This gives some later filers more time than they expect.
State-by-State Statute of Limitations (Sample):
| State | Deadline from Diagnosis |
|---|---|
| California | 2 years |
| New York | 3 years |
| Texas | 2 years |
| Florida | 4 years |
| Illinois | 2 years |
| Pennsylvania | 2 years |
| Missouri | 5 years |
Deadline-related facts to know:
- Wrongful death claims may have separate shorter deadlines
- The discovery rule may extend your window in some states
- Filing sooner is always better because evidence degrades over time
- Some MDL waves have closed to new claimants; remaining waves have capacity
If you are unsure whether your deadline has passed, getting a claim evaluation is the fastest way to find out. Legal teams can pull your state’s specific rules and calculate your window precisely.
Frequently Asked Questions
How much is the average Roundup lawsuit payout per person in 2026?
The average Roundup lawsuit payout per person is estimated between $150,000 and $200,000 for settled claims.
Individual amounts vary widely based on cancer severity, exposure history, and economic losses.
Jury verdicts in cases that go to trial have been significantly higher, ranging from tens of millions to over a billion dollars before appeal reductions.
What cancer do you need to qualify for the Roundup weed killer lawsuit?
You need a diagnosis of non-Hodgkin’s lymphoma to qualify for the Roundup weed killer lawsuit.
Accepted subtypes include diffuse large B-cell lymphoma, follicular lymphoma, mantle cell lymphoma, and marginal zone lymphoma.
Hodgkin’s lymphoma and most other cancer types are generally not accepted under current claim criteria.
Is the Roundup lawsuit still open in 2026, or has it already settled?
The Roundup lawsuit is still open in 2026. New claims are being accepted and evaluated.
While over 125,000 claims were resolved in Bayer’s 2020 settlement framework, thousands of additional cases remain active in federal and state courts.
Bayer has set aside approximately $16 billion in total reserves, and a significant portion remains unallocated to settled claims.
What proof do I need to file a Roundup weed killer lawsuit claim?
You need medical records confirming your non-Hodgkin’s lymphoma diagnosis and documentation of your Roundup use.
Proof of use can include witness statements, employer records, or personal testimony about where and how often you used Roundup.
Purchase receipts help but are not required; courts have accepted multiple forms of exposure evidence.
How long does a Roundup lawsuit take to settle?
A Roundup lawsuit settlement typically takes one to three years from initial filing to payment.
Cases with stronger evidence and more severe diagnoses may move faster through the evaluation process.
Claims filed in 2026 may benefit from streamlined processing as courts and administrators have refined their review procedures over years of similar cases.
The Stakes Are Real. Your Time Is Limited.
Bayer has already paid billions to Roundup users who developed cancer. The litigation is still active. New claims are still being accepted in 2026.
If you used Roundup and have a non-Hodgkin’s lymphoma diagnosis, your window to act is real and it is shrinking. Statutes of limitations are not flexible.
Get your medical records together. Document how long and how often you used Roundup. Then get your claim evaluated by a mass tort legal team before your state’s deadline closes the door permanently.
