The high 87% implied probability for a ruling in Monsanto’s favor stems primarily from the Supreme Court’s April 27, 2026, oral arguments in Monsanto Co. v. Durnell. In that case, the Court is considering whether the Federal Insecticide, Fungicide, and Rodenticide Act preempts state-law failure-to-warn claims when the EPA has not mandated a cancer warning on Roundup labels containing glyphosate. Justice questioning during arguments appeared to favor Monsanto’s preemption position over the Missouri Court of Appeals ruling that allowed the plaintiff’s claim to proceed. A decision is expected before the end of the October 2025 term in late June or early July, with the outcome likely to affect thousands of related Roundup liability suits. Trader consensus incorporates the Court’s recent history of narrowing state tort exposure in regulated product cases alongside the specific signals from argument.
