The Midterms Are Coming! What Does It Mean for Your Money?

Ahhh, election season. That wonderful time when your television fills up with political ads, your mailbox gets stuffed with flyers you immediately throw away, and suddenly everyone on social media becomes an expert on fiscal policy. Welcome to the 2026 midterm elections!

Normally, I try to keep politics out of trading because mixing political beliefs with investment decisions is generally a great way to lose money. The market doesn't care who you voted for, what bumper sticker is on your car, or which cable news network you watch. However, politics can impact markets. Tax policy, regulation, government spending, tariffs and energy policy all matter, and a change in control of Congress can alter expectations for all of them.

So rather than arguing about which party is "better" for the stock market, let's ask a much more useful question: What is the market currently expecting, and what happens if it's wrong?

Who Is Going to Win?

Obviously, nobody knows, but prediction markets can give us some insight. I like looking at Kalshi because, unlike a traditional poll, participants actually have money riding on the outcome. It's easy to tell a pollster you're 100% certain your candidate will win. It's a little different when someone responds, "Great, how much would you like to bet?"

As of August 2026, Kalshi traders give Republicans roughly a 58% probability of retaining the Senate, versus about 42% for Democrats. The House is another story. Kalshi's balance-of-power market currently puts roughly a 39% probability on Democrats winning both chambers, a 35% probability on Democrats taking the House while Republicans retain the Senate, and only about a 23% probability that Republicans maintain control of both chambers.

In other words, the market currently sees a Democratic House and Republican Senate as a very real possibility. Remember, these are probabilities, not guarantees, and we're still months away from Election Day. In politics, that's an eternity. One debate, economic report, geopolitical event, scandal or candidate saying something incredibly stupid into a live microphone can change things quickly.

Why Should Traders Care?

Republicans currently control the White House and Congress, making it easier for President Trump to pursue his legislative agenda. If Democrats capture one or both chambers, that changes the equation considerably.

For newer traders, here's an important concept: markets are forward-looking. Wall Street isn't going to politely wait until November to reposition portfolios. If the probability of a particular election outcome moves from 60% to 85%, money will begin adjusting well before Election Day. That means some of the biggest opportunities — and risks — could develop before the votes are counted.

There's also history to consider. The president's party typically loses congressional seats during midterm elections,  think of it as political mean reversion. Interestingly, while midterm years can generate considerable uncertainty leading into the election, the period afterward has historically been strong. BlackRock found that, going back to 1970, stocks historically began rallying about 22 trading days before midterms and averaged a 14.1% return during the following six months.

Before anyone loads up on leveraged calls because "Merlin said stocks are going up 14%," that's an historical average, not a forecast. If historical averages guaranteed future returns, we'd all be trading from yachts. What the statistic does show is that markets tend to dislike uncertainty more than they dislike either political party.

Three Possible Outcomes

Democrats take the House, Republicans keep the Senate: This may actually be the most market-friendly outcome because it creates one of Wall Street's favorite environments: gridlock. Major tax changes, spending programs and sweeping legislation become harder to pass. Washington may hate gridlock, but businesses often appreciate knowing that nobody can dramatically change the rules overnight.

Democrats take both chambers: This would create the biggest political shift. President Trump would retain veto power, but Democrats would gain considerably more influence over budgets, spending and legislation. Healthcare could see increased volatility around drug pricing and insurance policy, traditional energy could face greater regulatory uncertainty, while renewables could benefit from expectations of a friendlier legislative environment. I'd also keep a very close eye on the 10-year Treasury yield. If investors anticipate larger deficits or greater Treasury issuance, rising yields could pressure technology, growth stocks, REITs and utilities.

Republicans retain both chambers: Based on current prediction-market pricing, this would be more of a surprise. It would preserve Trump's ability to pursue policies involving taxes, deregulation, energy, defense and trade, potentially benefiting financials, traditional energy, defense and industrials. But don't automatically translate "Republicans win" into "stocks go up." Tariffs can be inflationary, deficits can push yields higher, and the Federal Reserve isn't going to ignore inflation because one party won an election.

Where Should Investors Look?

The sector implications aren't as simple as "Democrats buy this, Republicans buy that," but there are areas worth watching.

Notice there aren't many slam-dunk trades in that table. That's because markets are complicated. Sorry. If you're looking for easy answers, financial television has plenty of them.

Don't Trade Your Politics

This may be the most important takeaway. Investors routinely assume their preferred party winning means stocks will rise, while the other party winning means financial Armageddon is right around the corner. History simply doesn't support that conclusion.

J.P. Morgan Asset Management has examined market performance under different configurations of government going back to 1937. Stocks have made money under Democrats, Republicans and divided government because, over time, corporate earnings, economic growth, inflation, interest rates and valuations matter far more than the letter next to someone's name.

Between now and November, I'll be watching Kalshi's probabilities, the 10-year Treasury yield, sector relative strength and, of course, the Federal Reserve. Most importantly, I'll be watching price, because you can have the greatest macroeconomic thesis in human history and still lose money if price tells you you're wrong.

The Bottom Line

The 2026 midterms matter because control of Congress can influence taxes, regulation, spending, energy, healthcare and defense policy. Current prediction markets suggest Democrats have a strong opportunity to capture the House while Republicans remain favored in the Senate, making divided government a very real possibility.

But don't make the mistake of believing the election itself determines whether stocks go up or down. Historically, markets have often performed well following midterms as political uncertainty fades and investors return their attention to what ultimately drives markets: earnings, interest rates, inflation and economic growth.

So I'm not particularly interested in arguing about which party is "better" for stocks. I'm interested in two much more profitable questions:

What outcome is Wall Street already pricing in, and what happens if Wall Street is wrong?

Because that's usually where the best trading opportunities are hiding.
