What are prediction markets?
A prediction market is an exchange where you trade contracts on the outcome of real-world events. Each contract pays $1 if the event happens and $0 if it doesn’t. The price between zero and one dollar reflects the market’s collective probability. Unlike a sportsbook, that price is continuously discovered by the buyers and sellers in the order book.
In the United States, regulated prediction markets operate under CFTC oversight as derivatives exchanges, the same regulator that supervises commodity futures. This puts the product closer to oil futures with full transparency on volume, open interest, and settlement.
The most active market categories today are politics, sports, economics, and crypto. Liquidity has roughly tripled in the last 18 months, and several traditional brokerages have signaled plans to enter the space including ICE.
These are two-sided markets
Every buyer needs a seller. The price you see is what someone else is willing to take — not a number set by the house.
Continuous movement
Prices update tick-by-tick as new information arrives, giving a live probability for the event right up until resolution.
Cash settlement
Contracts cash-settle to $1 or $0 at resolution. This is a clean P&L on a binary outcome.
By the Numbers
How prediction markets work
Exchange publishes the question and rules
Every contract is worth exactly one dollar if it’s right and exactly zero if it’s wrong — that’s the whole payout structure. Since our market resolved No, every “No” contract pays out a full dollar, and every “Yes” contract expires worthless. If you bought “No” at 70 cents, you just made 30 cents on the dollar. If you bought “Yes,” that position is gone. The math is that simple by design. And it happens right away. The moment the market resolves, winnings are credited and you can withdraw — there’s no waiting period, no payout review, no haggling. Because everything was defined up front, the close-out is automatic. That predictability, from the first published question to the final dollar, is the entire appeal: you always know exactly what you’re holding and exactly what it’s worth.
The order book opens. Price emerges from real bids.
Once the market is listed, it goes live and the price starts to move on its own. Nobody at the exchange decides the odds. Instead, buyers and sellers post what they’re willing to pay, and the price settles wherever those offers meet — exactly like a stock. If a “Yes” contract is trading at 18 cents, the crowd is collectively saying there’s roughly an 18% chance the Fed cuts. As new information lands, people adjust their bids and the price drifts up or down in real time. This is what makes prediction markets different from a sportsbook. A sportsbook sets a line and you take it or leave it. Here, the line is just the running tally of what real people are putting real money behind. The price isn’t an opinion handed to you — it’s the market’s best live guess, updated every time someone trades.
You buy, sell and exit anytime.
Prediction markets don’t require you to hold a contract until the event happens. If you think the Fed’s going to hold rates steady, you buy “No” at whatever it’s trading for. If the price later moves your way, you can sell and pocket the difference without waiting for the meeting at all. And if you’ve got no edge, you do nothing — sitting out is a perfectly fine move, which is something a fixed-odds bet never really lets you do. That flexibility changes how you think about it. A contract bought at 30 cents and sold at 45 cents is a win, full stop, regardless of how the event eventually turns out. You’re trading your read of the probability against everyone else’s, and you can step in or step out whenever the price makes sense to you. Your risk is always capped at what you paid — you can’t lose more than you put into the position.
The named source is checked. Yes or No is declared.
When the market closes, there’s no debate and no judgment call. The exchange goes to the one source it named back in step one and reads off the answer. For our example, that source was the FOMC’s June statement — and on June 17, 2026, the committee voted to hold rates steady. The question was “Will the Fed cut rates in June 2026?” The answer was no, so the market resolves No. This is why the precise wording from step one matters so much. Because the question and the source were both nailed down in advance, resolution is just a lookup, not an argument. Everybody knew the rule going in, so everybody accepts the outcome coming out. There’s nothing to dispute because nothing was left vague.
Winners get $1, losers get $0. Funds clear instantly.

- Customer support has no 24/7 phone line, leaning on live chat and email, which is a gap in the US market.

Tips for trading on prediction markets
Having several options to consider is a good problem to have, but it can also lead to uncertainty about which is the best choice for you. When comparing prediction market platforms, you can keep it simple and begin by focusing on these key areas.
- Fees: Review the fee structure for any platform that you plan to trade with. It should be clearly defined and reasonable. Take the time to compare fees to help decide where to trade, as they can have a direct impact on your bottom line.
- Liquidity: If markets aren’t actively traded, prices can be skewed, and the appeal can be limited. Not every contract will be liquid, but you’ll want to make sure that there’s active and regular interest in the markets that you want to trade.
- Market depth: You’ll want to make sure that the platform offers all of the markets that you’re interested in trading. The industry leaders cover all of the bases, while others are more specific in focus areas, such as sports or politics.
- State availability: If a platform isn’t accessible in your state, it’s not going to do you any good. This applies to many of the sports-specific platforms. For others that operate nationally, availability could be subject to change.
- Banking and speed: Most of the leading platforms have several funding options to consider. You’ll want to make sure that your preferred methods are covered, whether it’s crypto or a traditional banking method.
- Accessibility: Some traders prefer apps, while others prefer the larger desktop experience. While many of the top platforms operate in both environments, make sure your preferences will be met.
- Registration process: For all regulated platforms, there’s a sign-up and verification process, with KYC protocols to meet. The registration process should be smooth and hassle-free, provided you do your part in verifying your details.
If you land on a platform that checks off all these boxes, you’ve landed on a solid option. One miss doesn’t signal automatic disqualification, but missing the mark in multiple areas could be a red flag on a platform where the potential for headaches outweighs the appeal.

Latest news and updates
Texas Senate Race Continues To Trade Like a Toss-Up as Paxton Holds a Thin Kalshi Edge
More than $10.6 million has traded on Kalshi’s Texas Senate market since the race turned competitive in August, while Polymarket traders now narrowly favor Democrat James Talarico. The split-screen comes as Republicans, including Sen. Ted Cruz, Senate Majority Leader John Thune and President Donald Trump, publicly acknowledge that Texas is no longer a race they can take for granted.
Over $106M Has Been Traded on LA’s Mayor Race as Bass Holds a Narrowing Edge
More than $100 million has traded on Kalshi’s Los Angeles mayor market, where Karen Bass remains near 65%.
Challenger Nithya Raman is gaining ground, has just secured the endorsement of the local Democratic Socialists of America chapter, and is running in a city where the general election is less a fight over party than a fight over what kind of Democrat gets to run Los Angeles.
New Jersey Asks Supreme Court to Decide Whether Prediction Markets Are Sportsbooks or Swaps
New Jersey has asked the U.S. Supreme Court to review its loss to Kalshi, giving the justices a direct chance to resolve the growing split over whether sports-event contracts are federally regulated derivatives or state-regulated gambling.
The petition comes days after the Ninth Circuit ruled for Nevada and against Kalshi, the opposite conclusion reached by the Third Circuit in New Jersey.
Polymarket Reportedly Hits $21B Valuation in New $1B Funding Round
Polymarket’s new funding round reportedly values the company at $21 billion, bringing it within striking distance of Kalshi’s reported $22 billion mark.
The deal is another huge vote of confidence in prediction markets, but it also lands as courts continue to question whether the sports contracts powering the sector’s growth belong under federal derivatives law or state gambling regulation.
New York Attorney General Asks Federal Court to Disregard CFTC Emergency Order to Kalshi
The Monday letter from NY AG James disputes the validity of the CFTC’s denial of Kalshi’s emergency rule change for consideration in the agency’s lawsuit against the state.
Kalshi Sanctions Congressional Candidate Laurie Buckhout Following Trades She Placed On Her Own Race
Laurie Buckhout, who is running to represent North Carolina’s first congressional district, faces a fine and has been suspended by Kalshi after she traded on markets related to the race she is a candidate in.
Ninth Circuit Deals Kalshi Major Blow, Rules Sports Event Contracts Aren’t CFTC-Regulated Swaps
The Ninth Circuit has dealt Kalshi one of its biggest legal losses yet, ruling that the platform’s sports-event contracts are sports bets—not swaps protected by the Commodity Exchange Act. The decision lets Nevada enforce its gaming laws against Kalshi’s sports products, deepens a circuit split with the Third Circuit, and raises the stakes for prediction-market operators facing state regulators around the country.
Connecticut Attorney General Escalates Action Against Kalshi Amid CFTC Lawsuit
Connecticut AG joins fray of colleagues taking to state courts to seek order limiting residents’ access to prediction market exchanges.
Responsible trading at prediction markets
As with any type of trading, there are risks attached to prediction markets. No matter how likely an outcome may appear to be, profits are never guaranteed. Contracts that are priced near certainty levels can suddenly move in the opposite direction as new developments arise.
One of the regularly highlighted benefits of prediction markets is the aggregation of the wisdom of the crowd. Unfortunately, that too can come with risk. The crowd isn’t always correct. If you follow blindly without assessing the situation for yourself, you’re taking unnecessary risks.
In markets that are liquid, entering and exiting positions as prices move is generally seamless. That’s not always the case in markets with lower volume. Slippage can happen while you await an order fill, and your set limit prices may not be readily accepted.
While the regulatory environment is out of the control of market participants, it is a situation that bears monitoring. Changes in availability or markets that can be traded could have an impact on your portfolio. Our news hub is the go-to spot to stay on top of the latest developments.
Lastly, the potential for a complete loss of your stake can happen on any trade. You should only trade with funds that you can afford to lose. As a general rule, your trading account should be limited to an amount that’s completely separate from what you need for living expenses.
Kalshi and Polymarket are regarded as the industry leaders in the US with the best apps. That doesn’t automatically make them the best fit for all users. You will want to consider factors like availability, fees, liquidity, and market depth to determine what you prefer the most.
Most platforms charge a trading fee that’s capped by the number of contracts traded, such as a maximum of $1.75 for 100-contract trades at Kalshi. Some also incorporate maker and taker fees based on liquidity impacts, and may charge nominal fees on select transactions, such as debit card withdrawals.
No. Prediction markets are based on event-contract trading on real-world outcomes. Under CFTC regulation, they’re considered a form of derivatives trading, not traditional gambling.
In the U.S., Kalshi tends to attract the most liquidity, while Polymarket is tops in international circles. Traders should also note that liquidity can vary by market. For example, a political topic may see more liquidity on Kalshi, while a crypto market could be more heavily traded at Polymarket.
No, availability varies by state. Kalshi and Polymarket advertise themselves as being available across the U.S. due to CFTC regulation, but have received pushback in some markets, specifically Nevada and New York. Platforms like DraftKings Predictions and FanDuel Predicts avoid certain states while being mindful of existing sports betting laws and regulations.
