Interactive Brokers Prediction Markets Review: Is Interactive Brokers legit?

How does Interactive Brokers Prediction Markets work?

Interactive Brokers (IBKR) is a prediction market site that provides traders with access to event contracts from three major US providers: Kalshi, CME Group, and ForecastEx. All you have to do is create an account with IBKR Prediction Markets, and you won't have to open separate accounts or fund each exchange individually.

One of the advantages of trading event contracts through IBKR Prediction Markets is that you can compare liquidity and event contract prices on all three exchanges before deciding where to trade.

Event contracts feature Yes/No positions. When a prediction market is resolved, a correctly predicted contract settles at $1, while a wrong prediction settles at zero according to the contract's terms. You can exit a position by selling your contract before the prediction market is resolved. However, whether you can do so depends on the available liquidity and the market prices at the time.

Moreover, event contract prices are determined by traders' collective expectations and fluctuate as new information enters the market. These prices also imply the probability of an event. For instance, if a Yes contract for a US election outcome is trading at $0.51, it implies a probability of about 51% that the event will occur. Likewise, a higher Yes price may indicate that traders view the event as more likely.

On prediction market sites such as IBKR Prediction Markets, event contract prices and the displayed percentages generally correspond. However, the numbers may not always align due to bid-ask spreads and order-book activity.

During my review, I noticed that the Yes and No prices may not always add up to $1.00 exactly. This is caused by differences between bid and ask quotes, plus market liquidity.

I found subcategories such as Cryptocurrency, Foreign Exchange, Commodities, Corporate Activity, Corporate Performance, and Stock Market Indices.

In the cryptocurrency market, IBKR features event contracts for Bitcoin, Solana, Dogecoin, Ethereum, XRP, Z Cash, and BNB. At the time of this review, Bitcoin Price at the End of 2026 had the highest trading volume at over $5.8M.

Technology

IBKR Prediction Markets supports trading artificial intelligence event contracts. I found markets such as "When Will OpenAI Achieve AGI?", "Best AI Base Model," and "US Grants License for New Nuclear Reactor Before 2027?"

Economic Indicators

The economic category is among the top markets on prediction sites. On IBKR Prediction Markets, there are subcategories such as Economic Activity, Education, Housing, Industry, Interest Rates, Labor, Oil & Energy, Price & Inflation, Sentiment Surveys, and Taxes.

Fed Decision and Hormuz Return to Normal markets were the most active during my review.

Government

There are only two subcategories within the Government category: Fiscal Policy and Government Actions. Some of the top markets I found include: "Donald Trump Announces Departure As President?" (excluding death), US-Iran Nuclear Deal?, and Who Will Leave Their Role in the Trump Administration in 2026?”

Environmental

You can trade event contracts on agriculture, climate change, temperatures, and weather on IBKR. At the time of my review, Highest Temperature in Los Angeles had over $562,000 in trading volume, ranking as the most active market.

By the time I finished assessing the categories on IBKR Prediction Markets, I didn't find sections for trading contracts on sports and entertainment events, unlike in my Coinbase review.

Bonuses for traders on Interactive Brokers Prediction Markets

Since there was no Interactive Brokers Prediction Markets promo code to claim a welcome offer, I wasn't really expecting a sign-up bonus. However, I received a $10 welcome bonus after opening an IBKR Prediction Markets account, whereas at Moomoo I didn't receive a sign-up bonus and no Moomoo promo code was provided.

All I had to do to access the bonus was register on the site. Some of the required details included my legal name, date of birth, address, citizenship information, contact information, employment details, source of wealth, net worth, trading account type, security questions, tax information, and a completed W-8BEN form. You must be at least 21 years old to register with IBKR Prediction Markets and claim the welcome bonus.

Interactive Brokers usability – What the prediction site looks and feels like

Once I signed up for my Interactive Brokers Prediction Markets review, I found a search bar to look up available markets or contract names.

Below the search bar were different market categories I could trade in, including elections, government, and environmental outcomes. When I clicked a category, its subcategories were listed. For instance, within the Economic Indicators category, there are subsections for Education, Housing, Interest Rates, and more.

On the bottom static bar, I found tabs such as Markets, Elections, and Search. The Election tab is a dedicated section that provides a broader view of congressional and gubernatorial prediction markets.

IBKR Prediction Markets also features trending markets where you can find popular contracts in different categories. Trading event contracts on the site is easy, given the interface.

By selecting an outcome, I could see the price history on a chart, view the contract price at the available exchanges, compare prices, and decide which exchange to trade on. I also observed that before clicking on a market, I could tell which exchanges offered event contracts for that market. The site features each exchange’s logo on the market banner to quickly identify them.

Despite the event contracts offered by different exchanges, I didn't find trading on IBKR Prediction Markets confusing. When I clicked the “Compare Market Rules” link, I saw a comparison table with details such as the market name, measured period, date and resolution, current status, payout date, last trade time, and more information about the same event on each exchange.

The side menu lists my account ID, buying power, total cash, daily P&L, and tabs for Settings, Alerts, and Two-Factor Authentication.

In terms of appearance, I could select either a black or white background theme by clicking the theme toggle. Different tabs are colored light blue, while Yes and No contracts are distinguished by green and red font and fills, respectively.

IBKR offers a mobile app for trading predictions on the go

On IBKR Prediction Markets, I wanted to trade event contracts on the go, just as I did during my Gemini review. Hence, I downloaded the IBKR Mobile on the Google Play Store and the Apple App Store for my devices.

The app currently has a rating of 4.0 or higher on both app stores. When I compared the IBKR website and IBKR mobile app, I realized they share many features. The major difference is the screen size display. I prefer trading on IBKR Mobile for the convenience of trading on the go and not having to log in via a browser each time.
