ForecastEx is a CFTC-regulated event contract exchange operated by the Interactive Brokers (IBKR) group, a major US brokerage. It is structurally the opposite of the crypto-native, on-chain venues most people associate with prediction markets: there is no wallet, no token, and no blockchain anywhere in the flow. You trade yes/no event contracts denominated in US dollars, and access is distributed through Interactive Brokers accounts, the same accounts people already use for stocks, options, and futures. Its most distinctive feature is that ForecastEx pays incentive coupons on held forecast contract positions, so capital parked in a long-dated position is not simply dead money the way it is on most venues.

This guide covers what ForecastEx is, how it works mechanically as a regulated exchange, what makes it different from Polymarket and Kalshi, who it is built for, and how to use CoinRithm to browse and research ForecastEx markets before committing real money.

TL;DR

• ForecastEx is a CFTC-regulated event contract exchange operated by the Interactive Brokers (IBKR) group. It is not on-chain and does not use crypto.
• Contracts are yes/no event contracts denominated in US dollars. Access is distributed through Interactive Brokers accounts, so there is no separate app or wallet to set up if you already have one.
• ForecastEx pays incentive coupons on held forecast contract positions, which is unusual: on most venues, money locked in a long-dated position earns nothing while it waits.
• Coverage skews toward politics, elections, US politics, and inflation/macroeconomics, and markets are typically binary (two-outcome).
• As of August 2026, CoinRithm tracks roughly 19,000 ForecastEx events in total, with roughly 5,000 currently open, at /en/prediction-markets/forecastex.
• You can paper-trade prediction market events on CoinRithm with mock USD ($10 min) before risking real money anywhere.

What Is ForecastEx

ForecastEx is a regulated event contract exchange built for a brokerage-style audience rather than a crypto-native one. It launched as the Interactive Brokers group's event-contract exchange (IBKR calls the products forecast contracts), and it operates as a CFTC-regulated venue. In plain terms, it is much closer in shape to Kalshi than to Polymarket: users trade dollar-denominated yes/no contracts on real-world outcomes, under a federal regulatory framework, with no blockchain in the loop.

The defining characteristics that separate ForecastEx from crypto-native platforms:

• Regulated exchange structure. ForecastEx is a CFTC-regulated exchange. That means published contract specifications, a rulebook, and federal oversight, rather than the smart-contract-and-oracle pattern used by on-chain markets.
• No crypto, no wallet. Contracts are yes/no event contracts denominated in US dollars. You do not need a crypto wallet, a token, or a bridge. If you have never touched crypto, nothing about ForecastEx requires you to start.
• Interactive Brokers distribution. Access is distributed through Interactive Brokers accounts. IBKR is a major US brokerage with a large existing client base across stocks, options, and futures, so ForecastEx did not have to build an audience from scratch.
• Incentive coupons on held positions. ForecastEx pays incentive coupons on held forecast contract positions. This is a genuinely distinctive design choice, and we cover what it means (and what to verify about it) below.
• Politics- and macro-heavy coverage. On CoinRithm's tracking, the largest categories are politics, elections, US politics, and inflation/macroeconomics. Markets are typically binary, two-outcome questions.

This positions ForecastEx as a regulated, brokerage-distributed venue oriented toward political and macroeconomic questions, reaching users through an account type many investors already hold.

How ForecastEx Works

The core mechanics follow the standard prediction market model: you buy a contract on a yes/no outcome, a winning contract pays out its full defined value at resolution and a losing contract pays nothing, and the price you pay reflects the market's collective probability estimate. That much is the same as every prediction market.

What matters on ForecastEx is the specific shape of the venue underneath.

1. Yes/No Forecast Contracts in US Dollars

Every market is a binary question: will this outcome happen or not. You can take either side. Contracts are denominated in US dollars, and your maximum loss on a bought contract is what you paid for it. There is no leverage-and-liquidation dynamic and no token whose own price adds a second layer of risk.

2. Access Through Interactive Brokers

You reach ForecastEx through an Interactive Brokers account rather than a standalone consumer app or a crypto wallet. For existing IBKR clients that is close to zero setup friction. For everyone else, it means opening a brokerage account, with whatever account approval and eligibility requirements Interactive Brokers applies. Those requirements are IBKR's to define, so check them directly rather than assuming.

3. Matched Prices, Regulated Settlement

CoinRithm's ForecastEx feed is built on current-day matched prices, meaning the prices you see reflect where buyers and sellers actually transacted on the exchange that day, plus completed-day metrics once a trading day closes. Settlement runs through the regulated exchange under its contract rules, not through a smart contract or an on-chain oracle. The trade-off is the usual one for regulated venues: you are trusting a supervised financial institution and its rulebook rather than trustless code.

4. Incentive Coupons on Held Positions

This is ForecastEx's most distinctive feature. The exchange pays incentive coupons on held forecast contract positions. On most prediction markets, money committed to a position that resolves months from now simply sits there earning nothing, which quietly penalizes long-horizon trades. ForecastEx's coupon design pushes against that: holding a position generates coupon payments while you wait. We deliberately do not quote a rate here, because the rate and its terms are ForecastEx's to set and can change; confirm the current coupon terms with Interactive Brokers before treating them as part of your expected return.

5. Resolution to a Defined Outcome

When the underlying event concludes, each contract resolves according to its official contract specification, and winning contracts pay out in US dollars. On a regulated venue, the specification is what governs resolution, not your interpretation of the question. For political and macroeconomic contracts, the exact data source and definition (which official result, which statistical release, which reading of it) is the entire game.

Prices as Probabilities

The same logic applies here as on every prediction market. A yes contract trading at 65% of its payout value implies roughly a 65% market-implied probability of that outcome. If you believe the real probability is higher, buying has positive expected value before costs. If you believe it is lower, the no side is the better position. Because ForecastEx contracts are binary dollar contracts, the price maps cleanly to an implied probability.

For the full probability and payout mechanics explainer, read How Prediction Market Probabilities Work.

Resolution Rules Are Non-Negotiable

Before trading any ForecastEx market, read the contract's resolution criteria. Regulated venues publish precise contract specifications, and the specification is what settles the market. For macro contracts specifically, check exactly which data release resolves the contract, from which source, and whether revisions matter. For political contracts, check what counts as the official outcome and when it is deemed final. These details decide who gets paid.

For a deeper walkthrough of how outcomes are determined across venues, read How Prediction Markets Resolve.

Not reading the rules is the most common reason experienced traders lose money on an unfamiliar venue.

What Makes ForecastEx Different

Most of the prediction market attention over the last few years has gone to on-chain venues and consumer apps. ForecastEx took a different route, and its differences are worth stating plainly.

• It is a regulated exchange from an established brokerage group. Interactive Brokers is a major US brokerage, and ForecastEx operates under CFTC regulation. That is a fundamentally different trust model from an offshore site or an unaudited protocol.
• It pays you to hold positions. The incentive coupon on held forecast contract positions is rare in this category. On most venues, the opportunity cost of locking dollars into a contract that resolves in six months is a hidden tax on long-horizon forecasting. ForecastEx's design reduces that tax, which makes patient positions on elections and macro outcomes structurally more attractive. Verify the current terms with IBKR before counting on them.
• It is dollar-denominated and wallet-free. No wallet, no token, no bridging. For a mainstream investor, that removes most of the operational friction and most of the operational risk of on-chain trading.
• It rides existing brokerage distribution. Access flows through Interactive Brokers accounts, so the venue plugs into an existing, sophisticated client base rather than needing to bootstrap a consumer audience.
• It leans into politics and macro. On CoinRithm's tracking, politics, elections, US politics, and inflation/macroeconomics lead the category mix. If your interest is Fed decisions, inflation prints, and election outcomes rather than sports, ForecastEx's book is oriented toward you. For the category context, see Election Prediction Markets and Economics and Fed Prediction Markets.

The honest summary: ForecastEx is trying to make forecasting a normal instrument inside a serious brokerage account, and it sweetens long-horizon positions with coupons instead of leaving parked capital idle.

Who ForecastEx Is For

ForecastEx is built for a specific profile:

• You want prediction markets without touching crypto, wallets, or tokens.
• You already have (or are willing to open) an Interactive Brokers account, and you want event contracts alongside your existing portfolio.
• You are interested in politics, elections, and macroeconomic questions more than sports.
• You take long-horizon positions and care that held positions earn incentive coupons rather than sitting idle.
• You are comfortable trusting a regulated exchange and its rulebook rather than trustless on-chain code.

If you specifically want permissionless, on-chain, crypto-settled markets, ForecastEx is not that; Polymarket and other on-chain venues fit that preference better. If you want a consumer-first standalone prediction market app, Kalshi is the closer comparison. If you want event contracts inside a serious brokerage account, with a coupon paid on held positions, ForecastEx is designed with you in mind.

Ground Truth: What We Know and What to Verify

This section is a direct honesty note. Some things about ForecastEx we can state with confidence from our own tracking; others should be checked at the source.

What we are confident about:

• ForecastEx is a CFTC-regulated exchange operated by the Interactive Brokers (IBKR) group.
• Contracts are yes/no event contracts denominated in US dollars, and access is distributed through Interactive Brokers accounts. It is not an on-chain venue.
• ForecastEx pays incentive coupons on held forecast contract positions.
• On CoinRithm's tracking, coverage is led by politics, elections, US politics, and inflation/macroeconomics, and markets are typically binary.
• CoinRithm aggregates its markets using current-day matched prices and completed-day metrics, and has tracked the venue since July 2026.

What you should verify directly with ForecastEx or Interactive Brokers:

• Current fee structure. We do not have ForecastEx's fee schedule and will not guess at one. Confirm current trading costs with Interactive Brokers before trading.
• The current incentive coupon rate and its terms. We describe the coupon qualitatively because the specifics are the venue's to set and can change.
• Eligibility and geographic availability. Access runs through Interactive Brokers accounts, and account approval, jurisdiction, and product-eligibility rules are IBKR's. Confirm your own eligibility.
• Account requirements, funding methods, and settlement timelines for your specific account type.

For any of the above, treat this article as directional and check ForecastEx and Interactive Brokers directly for current terms. We will not invent a fee number, a coupon rate, or an availability claim we cannot confirm. That is how users get misled.

ForecastEx vs Other Prediction Markets

The platforms differ along a few key axes. This is a directional comparison. For the full current comparison, use CoinRithm's prediction market compare page, and for the underlying method read How to Compare Prediction Markets.

The practical read: ForecastEx's closest peer is Kalshi, another regulated US venue, not Polymarket. The two big separators are distribution (a brokerage account versus a standalone consumer app) and the incentive coupon on held positions, which matters most for long-dated political and macro contracts. If you want permissionless on-chain markets, Polymarket is the on-chain option; see What Is Polymarket and What Is Kalshi for the full venue explainers.

These are not mutually exclusive. Many traders track several venues and route positions based on which one has better odds or liquidity for a given market. CoinRithm's prediction markets hub and sources directory are built for exactly that kind of cross-platform research. For a fee-by-fee breakdown across venues, see Prediction Market Fees Comparison.

How to Research ForecastEx Markets on CoinRithm

CoinRithm aggregates ForecastEx markets alongside Polymarket, Kalshi, Limitless, and others. You can browse odds, view odds history, and compare across sources without holding an account on every venue.

The dedicated hub for ForecastEx is: coinrithm.com/en/prediction-markets/forecastex.

As of August 2026, CoinRithm tracks roughly 19,000 ForecastEx events in total, with roughly 5,000 currently open. Coverage began in July 2026. The feed uses current-day matched prices while a trading day is live and completed-day metrics once it closes, so what you see reflects where the market actually transacted, not indicative quotes. Those counts move constantly as contracts open and resolve, so treat any snapshot as a point in time.

From the hub you can:

• See all aggregated open ForecastEx markets
• View current implied probabilities for each yes/no outcome
• Check odds history (24h, 7d, 30d charts where data is available)
• Compare ForecastEx odds against the same or similar markets on other platforms
• Read the resolving question and category without an account

Useful Research Steps Before Trading on ForecastEx

1. Check the odds on CoinRithm first

Open the ForecastEx hub and find the market you are interested in. Check whether a similar market exists on another venue. If ForecastEx implies 60% and Kalshi implies 66% on the same underlying question, that spread is worth understanding before you commit. For how to read cross-venue disagreement, see How to Compare Prediction Markets.

2. Read the contract's resolution rules

The market detail on CoinRithm surfaces the resolving question. On a regulated venue, the official contract specification governs settlement, especially for macro contracts (which release, which source, revisions or not) and political contracts (what counts as the official, final outcome). Read them before you open a position.

3. Factor in the holding period

ForecastEx's book skews toward elections and macro outcomes, which often resolve months out. Long holding periods change the math: your capital is committed for the duration, and ForecastEx's incentive coupons on held positions partially offset that cost. Confirm current coupon terms with IBKR, then include the holding period in your expected-value estimate rather than treating a six-month contract like a one-week one.

4. Track the odds history

The 24h and 7d trend on CoinRithm's market detail shows how implied probability has moved. A macro market that jumped after a data release, or an election market that drifted after a polling cycle, is pricing in information you should understand before buying at the new level.

5. Open on ForecastEx when ready

CoinRithm is a research and discovery layer, not a trading interface. Once you have done the research, place your trade directly through your Interactive Brokers access to ForecastEx. CoinRithm is not ForecastEx, is not affiliated with ForecastEx or Interactive Brokers, and is not a broker. CoinRithm is a research tool.

Paper Trading Prediction Markets on CoinRithm

If you want to practice prediction market thinking without risking real money on ForecastEx (or any other venue), CoinRithm supports paper trading for prediction market events with mock USD.

The minimum paper trade size is $10.

This lets you:

• Get used to reading odds and making probability judgments
• Track whether your reads are consistently good before scaling up
• Practice position sizing without real financial consequences
• Develop a research process before applying it to real money

Paper trading does not simulate execution costs, account funding friction, or the psychological weight of real money. But it is useful for building and testing a prediction market research process, and politics and macro questions are a good training ground because the resolution criteria are usually crisp. If you are consistently losing mock money, that is a good signal to pause before using real money on ForecastEx. Always research before risking real money.

Common Mistakes When Trading Politics and Macro Markets

ForecastEx's politics-and-macro orientation creates some specific failure modes worth flagging.

Not reading the exact resolution definition

Macro contracts resolve to specific data releases. "Inflation" is not a number; a particular print from a particular source on a particular date is. Political contracts have equally precise definitions of what counts as the official outcome and when. If your mental model of the question differs from the contract specification, you can be right about the world and still lose the trade.

Ignoring the holding period on long-dated contracts

An election contract that resolves in eight months ties up your capital for eight months. ForecastEx's incentive coupons soften this compared with venues where held capital earns nothing, but the time dimension still belongs in your expected-value math. A 5-point edge that takes a year to realize is a very different trade from a 5-point edge that resolves on Friday.

Confusing a probability with a prediction

A market at 70% is not saying the outcome will happen; it is saying roughly 7-in-10. Political outcomes at 70% fail three times out of ten, and a well-calibrated market will show exactly that over time. For why market prices beat gut reads (and where they do not), see Prediction Markets vs Polls and How Accurate Are Prediction Markets.

Trading the headline instead of the contract

News moves fast, and binary contracts are unforgiving about wording. A headline can be directionally true while the specific contract condition remains unmet. Before reacting to news, re-read the contract's condition and ask whether the news actually changes the probability of that condition.

Ignoring liquidity and spreads on quieter questions

Marquee election and Fed markets can be active; narrower questions can be thin. Entering a thin market means paying the spread immediately, and exiting early can cost you again.

Frequently Asked Questions

What is ForecastEx in simple terms

ForecastEx is a CFTC-regulated event contract exchange operated by the Interactive Brokers group. You trade yes/no contracts on real-world outcomes, mostly political and macroeconomic questions, using US dollars through an Interactive Brokers account. When the event resolves, winning contracts pay out in cash. There is no crypto and no wallet involved, and held positions earn incentive coupons while you wait.

Is ForecastEx legit

ForecastEx is a CFTC-regulated exchange operated by the Interactive Brokers group, a major US brokerage. That regulated structure is a meaningful legitimacy signal compared with unregulated offshore venues. As with any trading product, regulation reduces certain risks but does not remove market risk: you can still lose money, and you should confirm your own eligibility and the current terms with Interactive Brokers before trading.

How does ForecastEx work

You buy a yes or no contract on a defined outcome, denominated in US dollars, through an Interactive Brokers account. The price reflects the market's implied probability of the outcome. When the event concludes, the contract resolves per its official specification and winning positions are paid in cash. While you hold a position, ForecastEx pays incentive coupons on it; confirm the current coupon terms with IBKR.

What are ForecastEx incentive coupons

They are payments ForecastEx makes on held forecast contract positions. The practical effect is that capital committed to a long-dated contract is not idle: it generates coupon income while the position is open, which most prediction market venues do not offer. We do not quote a rate because the rate and its conditions are the venue's to set and can change; check the current terms with Interactive Brokers directly.

Do I need a crypto wallet to use ForecastEx

No. ForecastEx is not on-chain and does not use crypto. Contracts are denominated and settled in US dollars, and access runs through Interactive Brokers accounts. If you want a prediction market experience with zero crypto setup, that is one of ForecastEx's main selling points. If you want to practice without any account at all, CoinRithm's paper trading lets you trade prediction market events with mock USD ($10 min).

What fees does ForecastEx charge

We do not publish a fee number for ForecastEx because we do not have its current fee schedule, and inventing one would be worse than useless. Trading costs, account requirements, and the incentive coupon terms should all be confirmed with Interactive Brokers directly before you trade. For a cross-venue view of how prediction market fees generally work, see Prediction Market Fees Comparison.

What can I trade on ForecastEx

On CoinRithm's tracking as of August 2026, the category mix is led by politics, elections, US politics, and inflation/macroeconomics, and markets are typically binary two-outcome questions. CoinRithm tracks roughly 19,000 ForecastEx events in total with roughly 5,000 currently open. Browse the aggregated open markets at coinrithm.com/en/prediction-markets/forecastex to see current coverage at a glance.

Conclusion

ForecastEx is a prediction market built for a regulated, dollar-based, brokerage-account audience rather than a crypto-native one. CFTC regulation, Interactive Brokers distribution, a politics-and-macro-heavy book, and incentive coupons on held positions are its defining characteristics. It is much closer to Kalshi than to Polymarket, and it is the right fit if you want event contracts inside a serious brokerage relationship without crypto, wallets, or on-chain mechanics.
