Trader consensus on Polymarket prices a 67% implied probability that SCOTUS will bar counting mail ballots received after Election Day, driven by ongoing Republican-led litigation in battleground states like Pennsylvania, Wisconsin, and Nevada challenging extended deadlines amid tight national polls. The Court's October 22 shadow docket order, in a 5-4 split with conservative dissenters, declined to block Pennsylvania's three-day grace period for timely postmarked ballots, yet traders expect potential emergency docket intervention before November 5, given the conservative majority's history of enforcing uniform election rules as in 2020 Pennsylvania case. Close margins in swing states heighten stakes, with in-person voting trends favoring Republicans.
