How Prediction Markets Trading Works on PredictIt

Trading on PredictIt involves buying and selling contracts on political events.

First, you pick the political market you want to speculate on. Then you choose Yes or No, depending on whether you think the event will happen.

Each contract trades on a scale from $0 to $1. That price is what you pay for one share. If the outcome you bought wins, the contract settles at $1. If it loses, it settles at $0.

So if you buy a Yes contract at 61 cents, you’re risking $0.61 to win $1 if you’re right. Your profit on that one contract would be 39 cents, before fees. If you buy at 14 cents and it wins, you’d make 86 cents.

The contract price does more than show the cost of entry. It’s also giving you a live read on how the market is pricing the outcome. A contract near $1 means traders think that the result is very likely. A contract near $0 means the market sees it as a long shot.

For example, in Michigan’s Democratic Senate nomination market, Mallory McMorrow at 61 cents and Haley Stevens at 14 cents indicate that traders view McMorrow as the stronger candidate to emerge from that primary.

Those prices move all the time. News, polling, rumors, endorsements, and momentum can all push a contract up or down.

What Happens After You Buy a Contract

Once you buy a contract, you have a few ways to play it from there.

One option is to hold the position until the market resolves. If you’re right, the winning contract settles at $1. Your profit is the difference between the $1 payout and your entry price.

Let’s say you bought a Yes contract on Mallory McMorrow in Michigan’s Democratic Senate primary at 61 cents. If she wins the primary and you hold the contract through settlement, it cashes at $1. That means you make 39 cents per share before fees.

If she loses, the contract settles for $0, and the money you paid for it is gone.

That’s the basic trade. You’re risking the entry price for the chance to cash out at a dollar if your side comes through.

Many traders don’t wait for the market to settle. They buy a contract and sell before primary day to lock in a gain, cut a loss, or adjust the position as the race changes.

Say McMorrow opens at 61 cents, then a new poll drops, she lands a key endorsement, or Haley Stevens hits a rough patch on the trail. If traders start liking McMorrow’s chances more, her contract might climb to 72 cents.

At that point, you can sell and book an 11-cent gain per share before fees without waiting for the primary day.

You don’t have to sell the whole position either. You can sell part of your shares, book some profit, and leave the rest open in case the number keeps climbing. That gives you a way to take something off the table without fully stepping out of the market.

The same idea works on the downside.

Maybe McMorrow has a bad debate night, a weak fundraising update hits, or a headline shifts momentum toward Stevens. If her contract slips from 61 cents to 46 cents, you can sell early and cut the loss instead of holding all the way to settlement.

That’s a big part of how prediction market trading works. You’re not just trading on the outcome. You’re trading the market’s reaction as the race changes.

How Limit Orders Work on PredictIt

A limit order lets you decide the price at which you want to buy or sell a contract.

So if a contract is trading at 58 cents but you only want to buy at 54 cents, you can enter a limit order at 54 cents. Your order stays open unless the contract reaches that price. If it gets there, the trade goes through. If it doesn’t, nothing happens.

The main reason traders use limit orders is to control price. You’re not forced to buy after a contract jumps or sell after it drops. You can set your number and wait for the market to meet you there.

That helps a lot in political markets, where prices can move quickly on a poll, an endorsement, a fundraising report, a debate performance, or a Washington headline.

Say Mallory McMorrow is trading at 61 cents in Michigan’s Democratic Senate primary market, but you only want to buy if the price comes down a bit. You can place a buy order at 56 cents and leave it there.

If the contract slips after a good news cycle for Haley Stevens or after traders start taking profit, your order could go through at 56 cents. If McMorrow stays above that number, the order stays open.

You can use the same idea when you want to sell.

Let’s say you bought McMorrow at 56 cents, and later the contract rises to 68 cents. If you think the market could keep climbing, you might place a sell order at 72 cents instead of selling right away. If the contract reaches 72 cents, your shares sell there automatically.

You can do that with all of your shares or only part of your position. A lot of traders like selling part of their stake to lock in some profit while keeping the rest open in case the price keeps rising.

The downside is that a limit order only works if the market reaches your number. If the contract never gets there, you don’t get the entry or exit you wanted. Even with that, I’d still rather set my price than rush into a trade at a bad number.

PredictIt Pricing & Fees

ODDS ASSIST RATING: 25/40

PredictIt works as a peer-to-peer market. You’re trading with other users, not against the platform. PredictIt handles the transaction, but traders drive the price.

Every trade on PredictIt needs someone on the other side. If you're buying Yes, another trader has to be selling Yes. Both sides have to agree on the price before the trade goes through.

PredictIt doesn’t make its money the way a sportsbook does. It isn’t building a baked-in house edge into every market. Instead, it charges a 10% fee on profits from winning trades.

That fee is one of the bigger drawbacks for me. It only hits winning positions, but it can still take a pretty noticeable piece of your upside, especially if you trade often and stack a few good calls together.

Here’s how PredictIt compares with some other prediction market platforms on fees:

• Robinhood: $0.02 per contract
• Kalshi: $0.000175 to $0.004375 per contract for makers, and $0.0007 to $0.0175 per contract for takers
• ProphetX: 2% on all markets
• Novig: No fees

PredictIt lets users buy into a market for as little as $0.01 per contract. Position size is capped at $3,500 per contract, so there’s a firm limit on how much exposure you can take in a single market.

PredictIt Market Variety

ODDS ASSIST RATING: 2/12.5

PredictIt only offers politics markets across 5 categories:

• Elections. This is the broadest category on the site and probably the best place to start if you want the main stuff in one spot. It pulls together a mix of major election markets, so you can scroll through the biggest races and narratives without bouncing around the platform.
• Congress. This is where PredictIt gets more specific. You’ll see markets on House and Senate control, seat counts, individual Senate races, and other contracts tied to the balance of power on Capitol Hill.
• State/Local. This section covers races and issues further down the ballot. That includes governor races, redistricting questions, state court elections, ballot measures, and other local political fights that don’t always dominate the national conversation.
• World. The world gives you political markets outside the U.S., including foreign elections, leadership questions, and other government-related developments abroad.
• President. This category is all about the White House and the stories around it. You’ll find presidential nominee markets, general election contracts, approval-related questions, impeachment angles, and other markets tied to whoever is in power or trying to get there.

My Experience Using The PredictIt App

ODDS ASSIST RATING: 12.5/12.5

I wasn’t thrilled when I realized PredictIt doesn’t have a native mobile app. After using the platform, I came away less bothered by it. The browser version is easy enough to use that it never felt like a major problem.

The design isn’t as slick as OG, and parts of it look a bit old-school. Even so, it’s easy to browse, and that counts for more. Whether you’re new to prediction markets or already have some reps on similar apps, it doesn’t take long to get comfortable.

I think PredictIt is easy to use, mainly because it focuses only on prediction markets. Compared with platforms like Crypto or Robinhood, where you’re sorting through a bunch of other financial products, PredictIt feels less crowded and easier to move through.

Interface and Navigation

PredictIt is split into two main sections.

The first section is the news hub, and it’s pretty much a running feed of political drama. You’ll see updates on the latest developments, breakdowns of the stories moving markets, and general analysis of elections, Capitol Hill, and the broader news cycle. They’ve got a podcast in there, too, if you like following the latest election chatter in audio form.

The second section is where the trading happens. This is the Markets area, and it’s broken into five categories: Elections, President, Congress, State/Local, and World.

Inside each category, the platform shows how many markets are available right at the top of the page. So if you open World, for example, you’ll see a count like 28 markets.

The lobby filters are useful too. Trade volume helps you find the busiest markets. Price change shows which contracts are moving the most. New arrivals surface recently added markets, while expiring helps you find contracts that are getting close to settlement.

There’s a keyword search too, which is nice when you already know the candidate, race, or issue you want to find.

On each market tile, PredictIt shows the contract price along with trading activity, typically as total shares traded. That gives you a quick read on how active the market is before you click in.

Inside a PredictIt Market

Once you open a market, the first thing you’ll see is the activity chart at the top. It shows how trading has moved over time, so you can get a sense of how the market has been priced and where traders have been willing to buy or sell over the last 24 hours, 7 days, or a month.

Below that, you’ll see the contracts available in that market and the prices attached to each one. One small touch I like is that PredictIt shows the price in dollars along with a multiplier, which gives you a quick read on the potential payout compared to what you’re putting in.

Further down, there’s a comment section where users can discuss the market, react to news, and go back and forth on where they think the price should be headed.

There’s also a Rules tab, and I strongly recommend reading it before you trade. That section spells out exactly what has to happen for the market to settle, and it’s worth checking closely so you don’t end up with the wrong idea about how the contract will be graded.

Making a Trade

When you select a market, the trade slip opens with two tabs at the top for Yes and No. You pick the side you want to trade.

Below the tabs are sections for buy, sell, and limit orders. At the bottom, PredictIt shows the trade button and a multiplier that helps you see the potential payout relative to the amount you’re risking.
