Based on: Speculative
Polymarket assigns 85-92% probability to Democrats winning the House majority. Historically, the president's party has lost House seats in 18 of 20 midterm elections. President Trump currently holds a slim Republican majority, creating high vulnerability to the classic backlash effect. The full Democratic sweep (House + Senate) is priced at 62% on Polymarket, implying strong Democratic momentum specifically in the House. Prediction calibrated at 85% per market anchor — deviating significantly would not be justified given the historical pattern and consistent market data.

Missouri voters will decide on Amendment 3 on November 3, 2026 — a legislatively referred measure that would reverse the abortion rights enshrined by voters in 2024 and impose a broad abortion ban. Kalshi rates the probability of Amendment 3 passing at 14–19% (as of early October 2026), implying a rejection probability of ~81–86%. Polling shows 43% support, 44% opposition (±3 margin of error). Since the Dobbs ruling in 2022, US voters have rejected abortion restrictions at state level in seven consecutive votes (Kansas, KY, MT, MI, VT, CA, OH) — a robust historical trend. No specific Polymarket market found for this ballot measure.

The 1 October 2026 Léger poll places PQ at 29% (PLQ 25%), a clear lead. The vote-scope.com seat-projection model (50,000 simulations) shows a median of 66 PQ seats; the 60-seat threshold corresponds to roughly the 25th percentile of that distribution. No Polymarket market for Quebec 2026 found. The majority threshold is 63 seats (125-seat Assembly; platform's existing open prediction targets ≥64). A ≥60 prediction is fully consistent with the existing platform prediction (PQ ≥64) and adds information: it resolves TRUE even in a near-miss majority scenario. CAQ collapse (<10 seats) and PLQ recovery (≥30 seats) are already captured in separate open predictions.

All leading electoral models position the PLQ as the second-strongest party behind the PQ. 338Canada (as of October 3, 2026) projects 39 seats as its central estimate (90% CI: 33–44), PoliWave projects 34 seats, and 127QC 35–36 seats. The PLQ was polling at 25–26% of votes (Léger, October 1, 2026). The prediction market Lines.com assigns 65.5% probability to PLQ winning ≥ 28 seats; Cassandra calibrates the slightly higher bar of 30+ seats at 65%, as the lower tail of the model range does not fully rule out a sub-30-seat outcome.
