Interactive Brokers ForecastEx review
Our full tested review
Interactive Brokers has no published promo code for ForecastEx prediction markets. The operator offers something entirely else. That’s no separate commission on forecast contracts, and interest is paid on the collateral behind open positions.
Interactive Brokers has no published promo code for ForecastEx prediction markets. The operator offers something entirely else. That’s no separate commission on forecast contracts, and interest is paid on the collateral behind open positions.
Every other US prediction market operator charges for trades and pays nothing on the stake. The longer you hold a position, the more the carry works in your favor.
Interactive Brokers or ForecastEx doesn’t have a promo code for a sign-up offer. There’s nothing that even resembles a welcome bonus or a no-deposit offer for new players. The commercial terms are in the pricing model instead.
Forecast contracts on the platform have no separate commission. However, trading isn’t entirely free. The cost comes in the spread rather than a line.
Yes or No contracts for single events sum up to roughly $1.01 instead of the usual $1.00. CME contracts are a different product, and they follow standard IBKR futures commissions, instead of ForecastEx’s structure.
At most prediction markets, money behind open positions is idle until settlement. ForecastEx accrues interest when holding positions. The cost of the carry comes to you instead of slipping away.
This scales with time, and is beneficial on long-dated contracts, while intraday contracts accrue almost nothing.

Unlike Kalshi or other operators, ForecastEx prediction markets don’t list sport contracts.
What ForecastEx Lists Instead
| Category | Detail |
|---|---|
| Economics | Yes. |
| Climate and weather | Yes. |
| Politics | Yes. |
| Native sports markets | No. |
| CME event contracts | Available through the same Interactive Brokers account, but listed by the CME Group. |
| Further contracts | Added by self-certification. |
Compared to the three other prediction market operators, ForecastEx is the cheapest. The tradeoff is the lack of native sports markets. But there’s no commission due to the embedded spread cost, which comes at roughly a cent per contract pair. Interest paid on collateral is a strong ForecastEx feature that no rival offers.
Beyond the lack of sports contracts, ForecastEx also has thinner liquidity. It’s built for active, institutional traders rather than casual traders.

Before you assume that a contract fee applies, check the following points.
ForecastEx LLC is a CFTC DCM designated prediction market. It was licensed in June 2024. It also holds a DCO registration, meaning that it lists and clears its own contracts.
Access is intermediated by Interactive Brokers LLC, a CFTC-registered futures commission merchant. Settlement sources are named by the ForecastEx rulebook. The exchange lists the contract; the broker carries the customer.
As a predictions market, ForecastEx is regulated and available on a federal level. You need an Interactive Brokers account to access it. Robinhood also distributes ForecastEx contracts to its customers, but the cost is different.
State-level restrictions may apply to specific market categories. Check the ForecastEx legal states page to see what’s available where.
No, it doesn’t. ForecastEx doesn’t have a promo code nor a sign-up bonus. It’s not a sportsbook or casino, so its promotional value lies elsewhere. It’s in the pricing instead, with no commissions on forecast contracts, and interest paid on collateral behind open positions.
Interactive Brokers doesn’t charge commissions on ForecastEx’s contracts. CME events are reached through the same account. However, they follow standard IBKR futures commissions schedules. Check whether your selected venue lists an event contract before assuming it trades free or not.
Yes, it does. ForecastEx open positions accrue interest on the collateral when held. This is structurally different from every other venue in the USA in this category. Most will let the stake sit idle until settlement. At ForecastEx, the longer a prediction contract runs, the stronger the value.
Yes, on its published terms. Kalshi charges price-dependent taker fees, which peak at a 50c contract price. ForecastEx charges no commissions on forecast contracts. It pays interest on the collateral, so the longer you hold an open position, the larger the interest.
ForecastEx doesn’t list sports markets. It lists economics and economic indicators, political events, climate and weather, and further contracts added by self-certification. Interactive brokers provides access to CME Group’s own event contracts via the same account for a wider catalog.
Yes, you do. Direct access to ForecastEx’s contracts is provided through an Interactive Brokers account. You can use the IBKR desktop client, the mobile app, the client portal for browser access, or the ForecastTrader interface. There’s no ForecastEx mobile app. Robinhood also distributes some of ForecastEx’s contracts to its traders.
No. Robinhood has its own fee schedule, which is charged per contract per side. The underlying contract is the same as ForecastEx’s product, but the cost is different. Check the prediction markets tracker for the broader federal picture. Our ForecastEx legal states page lists the current availability of markets across US states.
