Robinhood’s support article on event contracts says you cannot open or close individual legs. That matters when the first result goes your way. It may raise the value of what remains, but it does not pay out that leg separately.

The whole combo needs a buyer

To close, you open Your positions, select the combo and choose Close position. Robinhood says opening or closing a combo needs both an exchange quote and a participant willing to take the other side, and that closing may be unavailable if nobody will. Combo orders use fill-or-kill, which means the entire order fills or it cancels. A close can therefore fail even though you can see the position in your account.

Picture a three-selection combo where the first event has won. The other two can still lose, so a buyer prices that remaining risk. They are not obliged to hand back your stake because one selection came in. A rising displayed value is also no guarantee of an exit at that value, so read the actual closing quote and check the final order status.

Canceling and closing do different jobs

Robinhood’s canceling and closing guide says a pending order can be canceled, but once an order fills it cannot be, even if it was an accident. Event contract trades are final once executed. Closing a position is a new trade at the available price, and if the market is closed or no buyer is available, you hold until expiration, when a correct contract pays $1 and an incorrect one pays $0.

The same guide warns that the app may let you submit certain custom combos with conflicting selections. Once filled, the order is final, so check the outcomes on the order review rather than relying on the app to catch a mistake.

What an early sale leaves you

Here is an arithmetic example, not a Robinhood fee schedule or a live quote. You pay $30 for a position plus $1 in opening fees, for a $31 cost. A buyer later offers $38 and a $1 closing fee applies. You receive $37, a $6 gain on the $31.

If you hold instead, the combo follows its settlement rules. Comparing a certain sale with the full payout, while ignoring the chance of losing the remaining selections, gives a false picture. Before you open a combo, decide whether you are willing to hold it if closing is unavailable. A position that only works if you can sell midway is a poor fit for an exit that depends on another trader.

Kalshi, Robinhood and Interactive Brokers are three routes in. Their catalogs and account rules are not the same.

Sources for the table: Kalshi climate markets, Robinhood’s event contracts overview and Interactive Brokers’ event contracts page. A shared label does not make the three catalogs identical.

Account rules differ

Robinhood says you need an approved Robinhood Derivatives account, which requires an individual brokerage account, US residency and age 18 or older, in a state where event contracts are offered. It adds that Maryland and Nevada residents cannot trade sports contracts, and that Michigan residents cannot open new sports contracts as of September 9, 2026. Interactive Brokers limits event contracts to eligible clients aged 21 or older. Check current eligibility before you open an account.

Choose the event before the app

For weather, identify the measurement. A daily high at a named airport, an hourly reading and a long-run climate indicator answer different questions. Our Kalshi weather settlement guide explains why a general forecast app may show a different number than the contract.

For economic subjects, IBKR’s materials describe contracts on rates and similar indicators. Match the release and the measurement period to the exact event you meant to trade.

Being right is not the same as a good trade

Paying 95 cents for a $1 contract that wins leaves five cents before charges. Losing it costs the 95 cents plus any fees. Knowing the subject does not remove the need to judge the price.

Settlement can also lag the news. Kalshi says some weather markets wait for the official source report, and in rare cases are delayed when preliminary and final figures disagree. A delayed payment should be checked against the contract’s timetable before you treat it as an account failure.

For the routes in detail, see our Interactive Brokers review, our Robinhood combo explainer and our prediction market hub.

Kalshi’s weather markets guide says each market names its settlement source in its rules, and that apps such as AccuWeather, iOS Weather or Google Weather may help with guidance but do not decide outcomes.

The daily contract names its evidence

Per Kalshi, daily high and low temperature markets settle on the final climate report issued by the National Weather Service for the listed station, typically released the next morning. Hourly temperature markets are different: they settle on The Weather Company’s reading at an exact time for the coordinates named in the rules. This article covers daily markets only. Do not apply it to hourly, precipitation or index markets without reading their own rules.

Read the station, date and condition together. A daily high at an airport is not the temperature near your home, and a range contract is not the same as an “or above” threshold.

Why public airport readings can look inconsistent

The National Weather Service explains in its airport temperature guide that the shortened five-minute reports carry temperature only to the nearest whole degree Celsius, and may not match what the station tracks internally. The station’s own record of the daily high and low is the most precise, and that is what feeds the Daily Climate Report.

The NWS observations FAQ gives an example. An actual reading of 80°F converts to 26.7°C, rounds to 27°C for the five-minute report, and converts back to 81°F on many websites. The daily extreme can also happen between public observations. So a row of readings on a weather site need not reproduce the official daily high.

Daylight saving time

Kalshi notes that the NWS climate reports record daily highs in local standard time. During daylight saving time, that means the high is recorded between 1:00 AM and 12:59 AM local time the next day, not midnight to midnight on your clock. Check the measurement period, not just the date.

When settlement waits

Kalshi says a daily market can be delayed in rare cases, for example if the climate report high is lower than an earlier preliminary figure, or if the high is not consistent with the 6-hour or 24-hour highs in the METAR reports. A short wait after a market closes is not by itself an account problem.

If a result looks wrong, save the contract wording and the source report with its date and issue time. That is better evidence for a support request than two conflicting app screenshots.

The cost also depends on which exchange supplies the contract, so one platform label is not enough to compare.

Account, venues and eligibility

IBKR’s event contracts page says its prediction markets platform gives access to three exchanges: Kalshi, CME Group and ForecastEx. Its disclosures say event contracts are available only to eligible clients aged 21 or older, and that ForecastEx contracts on US election results are limited to eligible US residents. Having an account does not mean you can trade every contract.

ForecastEx is an affiliate of Interactive Brokers, and IBKR’s disclosure says the displayed prices reflect market sentiment from ForecastEx and other registered exchanges. A 70-cent price is a market price, not a broker telling you there is a 70 percent chance.

Fees depend on the venue

IBKR’s published US schedule lists, per contract:

IBKR says clients introduced by another broker or managed by an advisor may pay more, and that rates can change.

Here is the arithmetic for 100 ForecastEx contracts at a hypothetical 60 cents. The position costs $60 and the opening exchange fee adds $1, for $61. A $100 settlement leaves $39 above that outlay, ignoring other costs. The same trade under the $0.02 schedule would cost $62.

That isolates the fees only. A price two cents worse costs more than a one-cent fee saving, so compare the same outcome, quantity and settlement wording before calling either venue cheaper.

ForecastEx positions close by taking the other side

IBKR’s ForecastTrader lesson says winners receive a standard $1.00 per contract and that positions can be exited at any time by taking the opposing side. In practice, closing a Yes position means buying the matching No, which offsets it.

A hypothetical example: you buy Yes at 60 cents, then later buy the matching No at 30 cents. Together they cost 90 cents against a combined $1 value, before fees. Confirm the order preview before you submit, and do not treat this as a closing instruction for Kalshi or CME contracts reached through IBKR.

The incentive coupon

ForecastEx contracts pay an interest-like incentive coupon, based on the closing market value of the position, accruing daily and paid monthly. IBKR’s prediction markets page listed 3.38% APY on November 2, 2026, and says the rate can change. On an unchanged $100 position for 30 days, that comes to about 28 cents on a simple 365-day basis. It is a payment attached to a risky position, not savings protection, and it will not rescue a badly priced short-term trade.

Who it suits

An eligible existing IBKR customer interested in economic releases or climate indicators has a concrete reason to explore ForecastTrader. For anyone who would open a new account for a single event, the paperwork may outweigh a small fee saving.

This review rests on IBKR’s public documentation, checked November 2, 2026. We did not fund an account, place an offset trade or test a withdrawal.

Who can play

Hard Rock says anyone aged 21 or older who is physically in Florida and has a verified Hard Rock Bet account can place these bets. Its Florida eligibility page names titles such as Cash Eruption and Cleopatra, and says more are coming. Hard Rock states that its online casino is not available in Florida, while its availability page lists a separate casino in New Jersey and Michigan.

What happens behind the animation

According to Hard Rock, each wager is decided by the outcome of an authentic, previously completed motor race, selected at random from an official database. Hard Rock explains that once the result is locked in, the game plays a video reveal, and that the video is for entertainment because the payout is already decided.

You do not pick a driver or study form. The race supplies the result, and the game supplies the theme, sounds and animation. Hard Rock’s newer title announcements repeat that amounts won are determined solely by the outcome of wagers on past motor races.

Titles differ in more than theme

Hard Rock’s own release notes show that the games come from different providers and carry different wager ranges. In its October 14 update, Buffalo Blitz III from Playtech listed a $0.20 to $20 wager range, while Lucky Box Baccarat listed $1 to $1,000. Its October 20 update listed $0.20 to $560 for Oktober Cash.

That matters if you are comparing the Florida app with a casino app in another state. A familiar name does not show that a Florida title has the same payout rules or return as a conventional slot with that name. We have not established a return-to-player figure for any of these games, so a figure quoted for the casino version of a title should not be carried across.

What to check before you compare

Look at the rules page inside the specific game, the wager range, and any promotion terms attached to your account. Hard Rock publishes separate terms for each offer, so read them in the app before you deposit.

That can surprise you when the same login opens both. A familiar account does not mean a shared spendable balance. If your Sportsbook balance shows $100 and Predicts shows $0, you have no buying power for a new prediction trade until you fund Predicts itself.

What FanDuel says about funding Predicts

FanDuel’s Predicts deposit guide lists three ways to add money: debit card, Apple Pay and online banking. It also says payment methods saved on other FanDuel products are not available in Predicts, so you set up the one you want to use there before placing an order.

What this does to your total exposure

Say you hold $100 in Sportsbook and add $50 to Predicts. You now have $150 across FanDuel, in two places that cannot spend each other’s money. If you later decide to move money, treat a withdrawal from one product and a deposit to the other as two separate transactions. FanDuel keeps a separate support article on how to withdraw funds from Predicts, so check that guide for the steps and timing.

Keep both balances in view before you add more money, so you do not end up funding more than you meant to.

If the balance still looks wrong

Check which product the app is showing, then your transaction history for that product. When you contact FanDuel support, name the product, the amount and the date, and do not post account or payment details publicly.
