Trump Impeachment Odds 2026: What Prediction Markets Say Before the Midterms
Prediction markets are pricing Trump impeachment odds ahead of the 2026 midterms. Here's what Polymarket and Kalshi data actually show — and how to trade it.
Prediction markets have become the most watched real-time indicator of political risk — more responsive than polls, more honest than pundits. With the 2026 midterms approaching, two questions dominate the markets: will Democrats retake the House, and if they do, will impeachment follow?
Here's what polymarket.com and Kalshi are currently pricing — and what the smart money is actually doing.

Current Impeachment Odds on Prediction Markets
As of mid-2026, markets are pricing impeachment as a conditional event: it depends almost entirely on whether Democrats win the House in November.
The logic is straightforward: a Republican-controlled House will not impeach a Republican president. If Democrats flip the chamber, the political calculus changes entirely — though even then, Senate conviction requires a 67-vote supermajority, making removal effectively impossible regardless of House action.
What markets are actually pricing is the probability of an impeachment vote — not removal.

What the 2026 Midterms Markets Show
The midterms themselves are the foundational bet. Before any impeachment trade makes sense, you need a view on the House.
Key things to watch on the prediction markets:
Generic ballot movement: When national polling shifts by 2–3 points, prediction market odds tend to overshoot in response, then correct. That's where trading opportunities emerge.
District-level markets: Both Polymarket and Kalshi have opened contracts on specific competitive races — PA-7, AZ-6, NV-3. These are more predictive than national averages and often lag the aggregate market.

How to Trade the Impeachment-Midterms Nexus
The most sophisticated trade here isn't a direct impeachment bet — it's building a position around the conditional chain.
The chain: Democrats win House → Impeachment inquiry launched → Impeachment vote → (Senate acquits)
Each step in that chain has a probability. The smart money on Polymarket trades the earlier steps because they're more likely and resolve sooner.
Practical approach:
1. Take a position on House control based on your view of the generic ballot 2. If you're long Democrats winning, consider a small position on impeachment inquiry as a correlated hedge 3. Monitor district-level races as leading indicators — they move before national markets

Historical Context: What Markets Got Right (and Wrong)
In 2020, prediction markets gave Trump a higher probability of winning than most polls suggested — and got closer to the final margin than FiveThirtyEight's models.
In 2022, markets correctly priced a smaller-than-expected Republican wave weeks before election night, while mainstream media was still calling for a red tsunami.
The lesson: prediction markets aren't always right, but they aggregate information faster than any other source. When markets diverge significantly from polls, that divergence is worth investigating.

Key Dates to Watch
The impeachment and midterms trade has several catalysts between now and November:
- July–August: Primary season completes, giving clearer picture of candidate quality in swing districts - September: First major polls of general election season; markets typically reprice sharply - October: Final debate season and any major news events (October surprises historically move prediction markets 5–10 points in 48 hours) - November 3, 2026: Election Day — all House contracts resolve
