Best Prediction Markets for Trading in September 2026: Reviews & Comparisons

The Best Prediction Market Apps in the US September 2026

Finding a reliable platform requires looking at trading fees, available markets, and regulatory compliance. We tested the top options available to US traders right now to see how they stack up. Below is a breakdown of the leading prediction apps, starting with our top overall pick.

1. Polymarket Prediction Market

Why it’s Ranked #1: Polymarket is arguably the most powerful prediction market in the world by volume, often handling more activity than any other platform. While its ranking was previously held back during a slow U.S. rollout phase, the official launch of its dedicated mobile app has cemented its top position.

Make no mistake, Polymarket is a true heavyweight in the prediction space. After securing a massive investment from the Intercontinental Exchange (the parent company of the New York Stock Exchange), the platform brings serious institutional credibility to the table. They also acquired a fully licensed CFTC exchange, meaning they now legally operate under strict federal regulation in the US. For traders looking for the widest possible range of prediction event contracts, this is often the first choice.

If Kalshi is the traditional bank of prediction sites, Polymarket operates more like a high-speed open network. It is famous for hosting markets on absolutely everything, from obscure pop culture debates to major economic indicators. Rather than just claiming to be transparent, Polymarket actually proves it by running its entire system on the Polygon blockchain. This means every single transaction, trade, and order book is publicly verifiable on the open ledger, ensuring the house cannot manipulate odds or hide liquidity behind closed doors. This infrastructure also frequently allows for much lower trading fees than what traditional financial competitors charge.

Currently, the fully compliant Polymarket US platform operates exclusively as a mobile app. After months of throttling access via a massive waitlist to handle strict identity verification (KYC) requirements, the platform officially opened its doors to the American public in May 2026. You no longer have to wait behind a velvet rope or secure a referral link to get your account set up. Downloading the iOS or Android app grants you immediate access to an incredible depth of niche events and a premier trading environment directly from your phone. New users can enter Polymarket promo code WSN at sign-up to claim the welcome bonus.

2. Kalshi Prediction Market

Why it’s Ranked #2: Kalshi sits behind Polymarket because it lacks Polymarket's crypto-native scale and market variety, but it stays ahead of Crypto.com and OG as the most established CFTC-regulated, cash-based exchange with the deepest liquidity of any dedicated exchange.

Kalshi is the first fully federally regulated prediction market approved by the CFTC, making it an incredibly safe and legitimate platform for US residents. While some alternative markets require complicated crypto setups to get started, Kalshi provides a seamless, cash based experience with incredible liquidity, consistently handling well over $1 billion in weekly trading volume.

When you compare Kalshi to other prediction market sites in the US, the difference is night and day. It completely bypasses the frustratingly low betting limits you will find on older sites like PredictIt, and it offers a much wider market catalog than the basic event contracts recently launched by brokerages like Robinhood.

By registering with the Kalshi promo code WSN, you get access to an app that perfectly bridges the gap between high finance and sports fandom. Thanks to their recent launch of NFL and NBA player props, you can trade CFTC approved contracts on specific athlete outcomes, like touchdown scorers or total points, right next to the exact same markets where you trade on Fed interest rates, pop culture events, and election results.

3. Crypto.com Prediction Market

Why it’s Ranked #3: Crypto.com ranks ahead of OG and Underdog because it already runs a live, high-liquidity CFTC-regulated market paired with a full crypto exchange, but it trails Kalshi's cash-based liquidity and Polymarket's market breadth.

While primarily known as a massive cryptocurrency exchange, Crypto.com operates a robust, fully CFTC regulated prediction market for US customers. In the past, these features were buried deep within their complex crypto ecosystem, which frustrated casual users. However, they recently solved this in 2026 by launching OG, a completely standalone prediction app that makes trading on sports, elections, and pop culture incredibly straightforward without needing to navigate a crypto wallet.

Despite having a new mainstream app, the main Crypto.com platform lets you fund trades by converting crypto from your Crypto.com wallet to USD instantly with no conversion fees, and if you are looking to join it be aware that you don't need any kind of special Crypto.com promo code. Because their prediction tools sit directly alongside your actual crypto portfolio, you can actively protect your investments. For example, if you own a large amount of Bitcoin, you can easily buy a "No" contract on Bitcoin rising to offset any potential market dips.

The platform also shines with its unique UpDown Options, which allow you to automatically exit a trade early if the price hits a predetermined ceiling or floor. This built-in risk management is a feature that almost every other prediction market completely lacks, giving traders a massive advantage when navigating highly volatile events.

4. OG Prediction Market

Why it’s Ranked #4: OG ranks behind Crypto.com because it's still building liquidity outside of sports and political markets, but it edges out Underdog and Robinhood with the only margin trading available on a regulated US platform.

While the brand is a new standalone app, OG is wholly owned by Crypto.com and functions as their dedicated sports trading platform. This relationship provides incredible technical stability because the app is powered by the exact same CFTC regulated derivatives engine that Crypto.com uses for its broader exchange. By moving its prediction market business to this specialized app, they have created a focused environment for traders who want to target sports, political, and economic outcomes without the clutter of a general cryptocurrency interface.

We currently rank OG at number four, trailing behind industry leaders like Kalshi and the main Crypto.com app. This gap is primarily because OG is a newer platform still building its overall liquidity for niche events. Despite this, its toolset is technically superior for active trading. Unlike its competitors, the OG platform was built to handle professional order types like limit orders and automated knockouts. These features allow you to set a specific price ceiling or floor to automatically exit a position, ensuring you can lock in a profit or cut a loss without having to constantly monitor the app. This level of automation is a massive upgrade over the simple market orders found on most other prediction sites.

OG is also the absolute best platform for maximizing your buying power. It is currently the first prediction market to offer margin trading, meaning you can use leverage to take a larger position on a high conviction prediction with a smaller upfront deposit. Use OG promo code WSN to boost your starting bankroll and claim the following offer: Trade $25, get $25 in rewards. All new users who sign up with promo code can grab this welcome reward. This makes it the premier choice for aggressive scalpers who want to treat event trading like a high speed derivatives market.

⚡ Payout Speed: 3 to 5 Days
💳 Payment Methods: PayPal, Apple Pay, Google Pay, Venmo, ACH, Debit Card, Wire, Plaid

📱 Android User Rating: 4.0
🍎 iOS User Rating: 4.2
📜 Licensed in: Available in 48 US States (Currently restricted in NY and AZ)

5. Underdog Predict

Why it’s Ranked #5: Underdog Predict ranks below the dedicated exchanges because it's still building depth outside of sports and pop culture and lacks a desktop trading experience, but its DFS integration gives it an edge over Robinhood's more generic approach.

Underdog is already a major player in daily fantasy contests, and its prediction platform is built directly into the Underdog Fantasy ecosystem. This integration provides incredible stability because the app is powered by the exact same reliable engine that millions of sports fans already use. By keeping these markets housed completely within its main app, Underdog has created a familiar, welcoming environment for users who want to trade on sports and pop culture without needing to learn a complex financial interface. Get up to $1,000 in Bonus Cash + a shot at $1,000,000! Make sure to use Underdog promo code WSNPLAY during sign-up to claim this incredible offer!

We rank Underdog Predict slightly behind dedicated platforms like Crypto.com primarily because it is still building its market depth for non-sports events and currently lacks a full desktop trading experience. However, its setup is perfectly designed for the everyday sports fan. Unlike its purely financial competitors, Underdog actually allows you to combine your traditional fantasy entries with prediction market positions into singular combos. This hybrid approach lets you build completely unique strategies that standard prediction sites simply do not support.

Underdog remains the absolute best prediction market platform for casual traders who value simplicity and low friction trading. Because it uses a straightforward flat fee structure, typically charging just two cents per contract upon purchase with no exit fees, and charges zero banking fees on deposits or withdrawals, you always know exactly what your trades will cost. This makes it the premier choice for users who want to focus on their sports and pop culture predictions without having to manage complicated variable fee schedules. Don't forget to use Underdog promo code WSNPLAY during sign-up to unlock your bonus!

6. Robinhood Prediction Market

Why it’s Ranked #6: Robinhood offers the easiest way to try event contracts for the millions who already trade stocks and crypto there, but with a narrower market selection than Kalshi or Polymarket.

Robinhood lands at number six on our list not because it lacks quality, but because it is explicitly designed for a different audience: the everyday retail investor. If you already trade stocks or crypto, Robinhood removes the friction of opening a totally new account. It seamlessly integrates federally regulated prediction markets into the exact same app you already use, making it the most accessible entry point for millions of Americans.

Convenience is the absolute driving factor here. Robinhood allows you to trade binary "Yes or No" Event Contracts directly alongside your Apple stock and Bitcoin portfolio. Rather than building an exchange from scratch, they route these trades through established derivatives platforms like ForecastEx. This means you get the stability of institutional markets wrapped up in Robinhood's incredibly clean, beginner friendly interface.

Rather than just claiming to be intuitive, Robinhood proves it with a strictly simplified pricing structure. Every single contract is priced between $0.01 and $0.99 and pays out exactly $1.00 if your prediction is correct. Whether you are forecasting political elections, S&P 500 daily movements, or even professional sports, the maximum risk and potential return are always entirely transparent before you hit buy. It is the perfect platform if you want to casually dabble in prediction markets and manage your risk without having to juggle a separate crypto wallet or specialized financial app.

How We Rate Top Prediction Market Platforms

Every platform on this page earns a score out of 5, calculated by averaging five factors we test firsthand. It is the same BetEdge method we use for sportsbooks and casinos, rebuilt for how event contracts work. Buying Yes or No shares is not placing a wager, so we dropped our standard betting metrics and scored the things that decide whether you keep your edge or hand it back.

Here are the five BetEdge factors for prediction markets, each scored out of 5:

• Markets & Liquidity: How many event contracts a platform lists and how deep the order books run. Thin liquidity traps your money and widens spreads, so we place live trades to measure how fast orders fill and how tight the Yes and No prices sit.

• Fees & Payouts: What each contract costs to open, close, and settle, plus the deposit methods and withdrawal speed. Prediction markets charge you directly instead of baking a vig into the odds, so a heavy fee schedule eats a winning strategy alive.

• User Experience: Interface quality and how quickly a new trader finds a market and places an order across mobile and desktop.

• Promotions & Bonuses: The welcome offer and ongoing promos, run through our EV calculator to expose the real cash value behind the headline number.

• Customer Support: Availability, response times, and whether the help actually solves the problem, tested across every channel a platform offers.

Two factors sit outside the score but decide whether a platform makes this page at all: regulation (we rank only CFTC-regulated exchanges and academic-exempt markets) and responsible trading tools. On every platform we rate, we deposit our own money, trade live, and test a withdrawal, spending a minimum of 12 hours across a full week before publishing, then revisiting each review monthly to keep the scores current.

What are Prediction Market Sites?

Think of a prediction market as a stock exchange for real-world events. Instead of dealing with traditional sportsbook odds, you are simply buying "Yes" or "No" shares on whether a specific outcome will happen. These shares are priced between one cent and 99 cents. If a share costs 60 cents, it means the market believes there is a 60 percent chance that the event will occur. If your prediction is right, every winning share pays out exactly $1. The biggest advantage is that you are never locked in. You can buy and sell your shares on an open market at any time before the event ends, allowing you to secure a profit early or cut your losses.

Are Prediction Markets Legal in the US?

Yes, federally. The Commodity Futures Trading Commission (CFTC) regulates event contracts as financial derivatives under the Commodity Exchange Act, which is why platforms like Kalshi and Polymarket operate nationwide instead of applying for a license in each state the way sportsbooks do.

The states are where it gets complicated. More than a dozen argue that a contract on a football game is a sports bet, whatever the CFTC calls it, and they have gone to court to say so. The CFTC has countersued to defend the platforms, filing against Arizona, Connecticut, Illinois, Kentucky, Minnesota, New York, Rhode Island, and Wisconsin.

Where things stand as of September 2026:

• Two appeals courts have now ruled, and they split - In April the Third Circuit held 2-1 that Kalshi's sports contracts are swaps under federal law, blocking New Jersey from enforcing its gambling statutes. On Aug. 28 the Ninth Circuit went the other way, ruling 3-0 that the contracts are likely not swaps and clearing Nevada to enforce its gaming laws against Kalshi, Crypto.com, and Robinhood. That direct conflict between two federal circuits is the fastest route to the Supreme Court.

• The fight is now at the Supreme Court's door - New Jersey petitioned the Court on Sept. 2 to overturn its Third Circuit loss, and Robinhood filed a second petition after the Ninth Circuit ruling. Kalshi's response in the New Jersey case is due Oct. 8. Kalshi has also asked the full Ninth Circuit to rehear the Nevada case en banc rather than take it straight to the top.

• More circuits are still deciding - The Fourth Circuit heard Maryland's case on May 7 and Kalshi remains live in the state while it waits. The Sixth Circuit is weighing conflicting district court rulings out of Ohio and Tennessee.

• A group of states have switched sports markets off - Nevada now enforces against the platforms after the Ninth Circuit ruling. Michigan won a preliminary injunction on Sept. 1 forcing Kalshi to geofence the state or face a $500,000 daily fine, and Robinhood agreed on Sept. 9 to pull its Michigan sports contracts and close open positions by Oct. 9. Washington restricted Kalshi earlier this year, and Robinhood stood down there too.

• Massachusetts is blocked but paused - The state won an injunction in January that is stayed while its Supreme Judicial Court weighs the appeal, so sports trading continues there for now.

• Minnesota tried an outright ban and lost, at least temporarily - The state made it a felony to operate or advertise a prediction market starting Aug. 1. A federal judge blocked the law five days before it took effect.

• Utah produced the first final ruling, and the platforms lost - On Aug. 4 a federal judge granted summary judgment to Utah, holding that federal commodities law does not override the state's gambling ban. Kalshi is appealing to the Tenth Circuit, which has already refused to pause enforcement while the appeal proceeds.

• New York remains a flashpoint - Attorney General Letitia James sued Kalshi on July 31. On Aug. 11 the CFTC invoked emergency powers ordering the platform to keep operating in the state, putting a federal agency and a state government in open conflict.

• Iowa is testing a middle path - Rather than ban prediction markets, Iowa lawmakers advanced a bill to license and tax them, the first state to move toward regulating the platforms instead of shutting them out. Kalshi has also sued Iowa's regulators.

• The federal rulebook is still being written - The CFTC proposed a framework in June for deciding which event contracts run contrary to the public interest. Comments closed on July 27 and nothing has been finalized. As drafted, it would permit most straightforward sports contracts while barring ones tied to injuries, officiating decisions, and in-game incidents.

Federal status cuts both ways for traders. These are financial instruments, so trading on non-public information is a federal crime rather than a terms-of-service problem, and prosecutors have already charged people over it.

Practically, check the platform before you deposit. Access shifts state by state as these cases move, and a market that was open last month may be geofenced today. Here's how the fight got here, newest first.

• Sept. 11, 2026 - Crypto.com petitioned the U.S. Supreme Court to review the Ninth Circuit's Nevada ruling, becoming the third party to seek review of the sports-event-contract question.

• Sept. 11, 2026 - North American Derivatives Exchange (NADEX) filed its own petition for certiorari on the same Ninth Circuit ruling.

• Sept. 10, 2026 - Connecticut issued cease-and-desist orders to nine prediction platforms (Polymarket, Coinbase, Crypto.com, Robinhood, ProphetX, Novig, Webull, Gemini, and Underdog Predict) and nearly 30 subpoenas to payment processors, app stores, and media, ordering them to stop offering sports event contracts to state residents.

• Sept. 9, 2026 - Kalshi petitioned the full Ninth Circuit for an en banc rehearing of the Nevada ruling rather than going to the Supreme Court, arguing the panel decision created a circuit split.

• Sept. 9, 2026 - Robinhood filed a petition for certiorari asking the Supreme Court to review the same Ninth Circuit ruling.

• Sept. 8, 2026 - The Tenth Circuit denied Kalshi's emergency motion for an injunction pending appeal, clearing Utah to enforce its gambling laws against sports event contracts.

• Sept. 4, 2026 - A federal judge in the Western District of Michigan signed a stipulation and order under which Robinhood agreed to stop offering new sports event contracts to Michigan customers and close open positions by Oct. 9, making it the second platform pulled from the state after Kalshi.

• Sept. 2, 2026 - New Jersey's attorney general filed a petition asking the U.S. Supreme Court to decide whether states can enforce gambling laws against Kalshi's sports event contracts.

• Sept. 1, 2026 - An Ingham County judge granted Michigan a preliminary injunction barring Kalshi from offering sports event contracts, requiring geofencing through a state-licensed provider and a $500,000 daily fine for violations.

• Aug. 31, 2026 - New York Attorney General Letitia James asked the Southern District of New York to disregard the CFTC's Aug. 11 emergency order, arguing it merely restated legal arguments that multiple courts had already rejected.

List of All Prediction Market Sites and Apps in the US

Driven by major legal breakthroughs and soaring trading volumes, prediction markets have officially evolved from a niche financial corner into a mainstream alternative to traditional sportsbooks. With several major operators now live for real-money trading nationwide, platforms are aggressively competing for users by rolling out the best prediction market bonuses and welcome perks.

Before diving into your first event contract, here is an unranked overview of all the active prediction market platforms currently operating in the US, detailing how they stack up across their offerings, user experience, regulatory compliance, and market specialization.

If you are still undecided, we have a head-to-head comparison of the biggest prediction market apps in the US. You can check the actual differences to find the right prediction market for you.

Prediction Markets vs. Traditional Sportsbooks: Key Differences for Users

Prediction markets and traditional sportsbooks may look similar on the surface, but the mechanics behind the scenes are vastly different. Here is a quick breakdown of prediction markets vs. sportsbooks:

How Are Prediction Market Winnings Taxed?

One of the biggest and most overlooked perks of a regulated prediction market is how the IRS treats your money. Because the CFTC regulates sites like Kalshi as financial exchanges, they don't count as "gambling" platforms under the law. Our guide to gambling taxes explains how the sportsbook side is taxed.

Win a bet at a sportsbook and the IRS treats it as ordinary gambling income. Trade contracts on a regulated prediction market and those count as financial assets instead. So your profit is usually taxed as a short-term capital gain, reported on IRS Schedule D, just like day trading stocks.

A big sportsbook win comes with a W-2G gambling tax form. Prediction markets don't use W-2Gs. They track your profits and losses for the year and send you IRS Form 1099-B at tax time (or a 1099-MISC for academic sites like PredictIt).

This is where prediction markets pull ahead. Starting in 2026, the One Big Beautiful Bill Act tightened how sports bettors deduct losses. Recreational gamblers can now write off only 90% of their losses against winnings, and only if they itemize. That creates "phantom income." Win $10,000 and lose $10,000 in a year and you have broken even, yet you still owe tax on $1,000.

Prediction markets skip that penalty. Your trades are capital assets, so losing trades offset winning ones in full. You can apply 100% of your losses against your profits, and you don't have to itemize to do it. If your losses beat your gains for the year, you can even use up to $3,000 of the difference against your regular income.

• Community-backed ratings Our experts know the math, but we also rely on the wisdom of the crowd. We actively track feedback from our visitors, incorporating your real-world experiences with these prediction platforms directly into our final ratings.

Trading Responsibly and Managing Risk on Prediction Markets

Prediction markets aren't legally classified as gambling, but the money at risk is real, and so is the pull to keep trading. Because every platform on this list is CFTC-regulated, your funds are held to the same anti-fraud standards as a stock brokerage. That protects you from a platform collapsing or manipulating prices. It does nothing to protect you from a bad trading decision, and the constant price movement, real-time news reactions, and ability to buy and sell instantly can make event contracts feel a lot closer to sports betting than to long-term investing.

A few habits keep that risk in check:

• Set a trading budget before you start, not after. Decide what you can afford to lose in a week or a month, and treat that number as fixed. Don't fund a new deposit because a previous trade went against you.

• Size your positions. Putting your entire balance into a single contract, even one you feel certain about, removes any room for being wrong.

• Be extra careful with leverage. Margin trading multiplies losses exactly as fast as it multiplies gains. If you don't fully understand how a margin call works, skip it.

• Don't chase a loss. Doubling down on a worse price after a trade moves against you is the same instinct that drives problem gambling, whether or not the product is technically a "bet."

• Step back if trading starts affecting your mood, sleep, or finances outside the platform. Checking prices compulsively, hiding your activity, or trading with money set aside for bills are signs it's time to take a break.

The capital loss tax treatment covered earlier is a real financial advantage over traditional sportsbooks, but it's not a safety net. A trade that loses money is still money lost, deduction or not.

If prediction market trading stops feeling like a calculated decision and starts feeling compulsive, WSN's Responsible Gambling center can help you recognize the signs, and the National Council on Problem Gambling helpline (1-800-GAMBLER) is free, confidential, and there when you need to talk to someone.
