Third Trump Impeachment Talk Grows as Kalshi Odds Favor Democrats

What’s going on here?

A third impeachment of President Donald Trump has become a live campaign topic weeks before the November 3 midterms. At an October 1 rally in Oklahoma, Trump told supporters that if Republicans lose, Democrats would impeach him. House Speaker Mike Johnson predicted on October 6 that a Democratic majority would move within its first day or two. Several Democrats, including Rahm Emanuel and James Carville, have urged the party not to try. House Minority Leader Hakeem Jeffries has said Democrats have ruled nothing in or out. On Kalshi, a prediction market, traders price a 66% chance of impeachment before 2028.

What does this mean?

First, the basics. Nothing has happened yet. Winning the House would not by itself start an impeachment; it would only change which party controls the chamber that can bring charges. The House can impeach with a simple majority, while conviction in a Senate trial needs two-thirds of senators present. Trump was impeached twice before, in December 2019 and January 2021, and the Senate acquitted him both times.

The odds explain why the debate is heating up. According to Kalshi, its markets put the chance of impeachment before 2028 at 66% and before March next year at 26%. The chance of impeachment and removal is much lower, at 17%. Kalshi's balance-of-power market showed a 63% chance of a Democratic sweep of both chambers on October 3, a 30% chance of a Democratic House with a Republican Senate, and 8% for a Republican sweep. Its separate Senate market put Democrats at 63%, up from 49% on September 14. Fox News, citing projections, reported Democrats on track for 215 House seats to 201 for Republicans, with 19 toss-ups. Prediction markets reflect traders' bets, not certainties, and can move quickly.

Each side is using the issue for its own reasons. Trump and Johnson have framed impeachment as a reason for Republican voters to turn out; The Hill described Johnson's remarks as both a warning and a campaign message. Johnson also says Republicans will keep the House. Among Democrats, the split is sharper. In September, 147 House Democrats backed impeachment articles forced to a vote by Rep. Al Green, while Jeffries and other leaders voted "present." Caucus chair Pete Aguilar called the topic something right-wing media wants Democrats to discuss. Emanuel, Carville and former adviser Dan Turrentine argued that a Senate conviction is out of reach and that investigations would be a better use of time.

That points to what may matter more for investors: oversight and gridlock. Democrats, including Sen. Maggie Hassan and Rep. Robert Garcia, are reportedly preparing investigations into administration officials and the president's family. A split or Democratic Congress would also make it harder to pass new White House priorities, such as Trump's proposed $5,000 payments to adults, which have been estimated to cost more than $1 trillion.

The bull case

Historically, markets have often been able to live with divided government, partly because gridlock limits sudden policy shifts. With Kalshi pricing removal at just 17% and a two-thirds Senate vote needed to convict, a change in leadership looks unlikely. Investors may treat impeachment headlines as political noise and focus instead on earnings, interest rates and the economy.

The bear case

A Democratic House focused on investigations and possible impeachment could tie up Washington for much of 2027. That might delay budget work and other legislation, add uncertainty around spending and tariffs, and keep political risk in the headlines. Even if removal is unlikely, a long fight could weigh on sentiment and make markets more sensitive to bad economic news.
