How do you bet on elections and political events?

Q: How do you bet on elections and political events?

You bet on elections at prediction markets like Kalshi, Polymarket, and FanDuel Predicts. Not at a sportsbook. You buy a contract in cents. It pays $1 if the outcome you backed is correct. Markets exist for party control of Congress, individual Senate and House races, and the presidency. Election contracts can stay open for weeks after election night. Read the settlement terms on each contract before you buy.

Short answer

Election bets live on prediction markets, not sportsbooks.A contract at 68 cents means the market prices in roughly a 68% chance.Contracts can take days or weeks to settle after election night.Line shop across platforms the same way you do for sports.

If you follow politics and sports, you've probably wondered whether you can bet on who controls Congress. You can. These bets don't live at a sportsbook. They live on prediction markets. The contract mechanics work just like betting on a game.

Where election bets live

US sportsbooks don't take election bets. Prediction markets do. Platforms like Kalshi, Polymarket, and FanDuel Predicts offer markets on party control of Congress, individual Senate and House races, and governor contests. Kalshi and Polymarket are both CFTC-regulated exchanges. FanDuel Predicts runs under a similar federal framework.

Three types of markets you'll find

▸Party control markets: 'Republicans win Senate majority' or 'Democrats win the House.' One yes/no contract for the whole chamber.

▸Individual race markets: 'Candidate X wins Ohio Senate seat.' One contract per race.

▸Seat-count markets: 'Republicans win 52 or more Senate seats.' These pay based on a specific range, not just who controls the chamber.

How to read the price

A contract at 68 cents means the market prices in about a 68% chance. You pay 68 cents. If your side wins, you get $1. If it loses, you get $0. Same math as any prediction market bet.

You can also sell before the race is called. Say you bought at 68 cents and the price moves to 81 cents. You can sell and keep the difference. You don't have to wait for results.

A worked example

Say 'Republicans win Senate majority' is trading at 68 cents. You buy 50 contracts.

50 contracts x $0.68 = $34.00 cost. Republicans win: 50 x $1.00 = $50.00. Profit: $16.00. Democrats win: $0.00. Loss: $34.00.

Same arithmetic as any prediction market contract. The main difference is how long you wait for the result.

Now say 'Democrats win Senate majority' is trading at 35 cents on the same platform. Add the two prices: 68 + 35 = 103. That extra 3 cents is the market's built-in margin. Buying both sides costs $1.03 and returns exactly $1.00. You cannot lock in a guaranteed profit by taking both sides.

How elections differ from sports bets

The structure is different from what most sports bettors are used to. Here's how they compare:

	Sports bet	Election bet
Where to place it	Sportsbook	Prediction market
Contract format	Spread, moneyline, or total	Yes/No contract priced in cents
Settle time	Same night, usually within hours	Hours to weeks depending on the race
Exit early?	Cash out if the book offers it	Sell on the order book any time someone bids
Bet against	Usually the house	Other traders on the exchange

When do election contracts settle?

Most platforms settle when major news outlets call the race. Not when votes are officially certified. Some contracts settle on inauguration day. A race called on election night settles fast. A close race that goes to a recount can sit open for weeks. Your money is tied up the whole time either way.

Read the settlement terms on the exact contract before you buy. The contract page will spell out the specific trigger. 'Majority' can mean different things on different platforms. Confirm that definition too.

Before you buy

Check the settlement date and the settlement trigger. A contract that takes 3 weeks to close ties up capital you might want for other bets. It takes about 30 seconds to read the terms. Do it every time.

Line shopping works here too

The same Senate race can trade at different prices on Kalshi versus Polymarket. A 2-cent difference on 100 contracts is $2. That's not a big number on one bet. But across a full election cycle with dozens of races, it adds up the same way it does in sports.

▸Check prices on both platforms before placing.

▸Look at the spread between the best bid and the best ask. A wide spread makes it harder to exit early at a fair price.

▸Smaller races like individual House contests often have wider spreads than major Senate or presidential markets.

The contract math is the same as any other prediction market bet. Two things are different: the longer hold time and the need to read the settlement terms. Everything else you already know from betting on sports applies here.
