Kalshi was the first regulated financial exchange dedicated to trading event contracts by the Commodity Futures Trading Commission, an independent federal government agency that regulates commodity exchanges. Kalshi and Polymarket US have become two of the largest prediction market apps in the country for event contracts in terms of U.S. trading volume.
Kalshi's platform is easy to use and intuitive, and it's a breeze to deposit or withdraw your money. The site's promo for new users offers $55 in bonus trading credits after trading $25 or more on Kalshi.

What we like:
No trade limits: Because Kalshi is a regulated peer-to-peer trading platform, the only limit to how large of a trade you can make is the amount of shares available at the particular price point you're seeking.
Availability of real-time data: Users can see each other's trades live, which can help you predict pricing changes, set trading thresholds, and help you understand what sort of information causes markets to swing.
Easy cash out: During live sporting events, you'll often have the ability to sell shares at a profit or to reduce liability.
Low trading fees: Kalshi's fee structure varies, but on Yes/No events like the ones typically offered in sports prediction markets, the fees average around 1.4% per transaction, and there are no deposit or withdrawal fees for ACH/Wire transactions.
What could be better:
More player prop offerings: Users who come from a sports betting background might notice that Kalshi currently offers a somewhat limited number of player props, and some props like yardage or points scored are heavily banded (yardage slides by 10 yards and points by five points).
Liquidity: For more niche markets, liquidity issues (the amount of total money available) can make it extremely difficult to enter or exit certain positions.
What is Kalshi best for?
Kalshi is currently the easiest to use platform in the United States because of its instant deposits, fast withdrawals and a very large catalog of sports markets. It's particularly good for people who want the ability to choose Yes or No outcomes in sports markets. Claim the Kalshi promo code CBSSPORTS55 now:
Polymarket US
Polymarket.com exited the United States market in 2022 because it hadn't registered with the CFTC. It acquired a regulated exchange in 2025 and launched in the U.S. via the Polymarket app, though some markets on the Polymarket global site may not be available on the regulated Polymarket app, the only place you can claim the latest Polymarket promo code. In summary, the Polymarket global site and Polymarket U.S. app are two separate products.

Polymarket sign-up offer | |
Available states* | All U.S. states (except NV), Washington D.C. and U.S. territories |
Platforms | iOS / Android / Web |

*Some markets on the Polymarket global site may not be available on the Polymarket U.S. app.
Polymarket returned to the United States after purchasing QCEX last year. Now, the Polymarket promo code above allows new users to claim a "Deposit $10, get a $25 trading bonus" offer.
Because of its trading volume from around the world, Polymarket offers a wide variety of markets and generally benefits from great liquidity (although niche markets always present some problems). Note that many markets globally are not available on the Polymarket U.S. app. However, most sports prediction markets are available.
Like Kalshi, it uses a peer-to-peer trading exchange and offers Yes/No event contracts with plenty of tools to analyze trading volume in real time. Claim the Polymarket promo code CBSSPORTS here:
What we like
Plenty of options: Polymarket offers an incredible variety of trading options.
Phone-friendly interface: The Polymarket app currently only takes up 155 MB of storage on your phone, and an incredibly intuitive interface allows you to make trades quickly, a major advantage in fast-moving markets.
Lowest fees in the industry: Polymarket only charges a 0.01% fee on take orders, so you'll be charged less than a penny ($0.0075) on a $75 trade.
What could be better
Market availability: Polymarket does not offer its full library of markets on the Polymarket US app. However, most sports prediction markets are available.
What is Polymarket best for?
This is a massive prediction market platform, and if you're looking for a large variety of offerings with a lot of money moving, you'll be hard-pressed to find a better option. For sports in the United States, Kalshi might have more offerings. However, it's probably only a matter of time before Polymarket develops a competitive market catalog in America.

What could be better

What is Underdog Predict best for?
If you're already an Underdog player and live in a state where its prediction markets are available, you already have access to them and might not even realize it. Underdog Predict is best for DFS, Best Ball and Pick'em fans who want to seamlessly switch between those games and try out trading on sports event contracts within the Underdog Predict tab of the Underdog app. Claim the Underdog promo code CBS here:
FanDuel Predicts
Another prediction market spinoff of an industry leader in sports betting, FanDuel Predicts offers Yes/No event contracts via a familiar platform.

FanDuel Predicts sign-up offer | Get up to $100 in Bonus Credits When You Trade $1 for 5 Days |
Available states* | Available in all states |
Platforms | IOS/Android |

*Note that sports prediction markets are only available in AK, AL, CA, DE, FL, GA, HI, ID, MN, ND, NE, NM, OK, RI, SC, SD, TX and UT
Once again, familiarity is key here for FanDuel Predicts, as it's backed by online sportsbook leader FanDuel and financial services provider CME Group. Sports prediction markets are only available in 18 states, a major increase from five at launch in Dec. 2025.
FanDuel Predicts, like many other prediction markets, offers a promo to new users. By trading just $1 a day for five straight days, users get $100 in bonus credits ($20 per day). This sign-up bonus allows new users to test this prediction market platform without making a significant financial investment. However, users will have to navigate intrusive live-trading prompts, and there is a limited number of withdrawal options available.
What we like
Familiar app layout: While you will have to download a separate app to use FanDuel Predicts, the layout is easy-to-use for anybody who has previously used FanDuel, and the learning curve is small for newcomers.
Strong sign-up bonus: By trading just $1 a day for five straight days, users get $100 in bonus credits. Users get $20 in bonus credits per day by trading $1 for five days.
Backed by CME Group: Chicago Mercantile Exchange Holdings is a longstanding financial services company.
What could be better
Market availability: Sports prediction markets are only available in 18 states, and the limited user pool has led to a general lack of available markets for each game, as well as liquidity issues.
Withdrawal limitations: FanDuel Predicts currently only authorizes certain banks for withdrawals, so getting funds out can be a difficult process, depending on the options available to you.
What is FanDuel Predicts best for?
This product is best suited to users with previous FanDuel experience, but if FanDuel can leverage its marketing reach to improve liquidity, this platform could grow quickly.
PrizePicks Team Picks
A partnership offering Kalshi prediction markets through the PrizePicks app.
PrizePicks Team Picks | No promo code required |
PrizePicks Team Picks sign-up bonus | Play $5, get $50 in bonuses |
Available states | AK, AL, AR, CA, FL, GA, HI, IA, ID, IN, KS, LA, MN, MO, MS, MT, NC, ND, NE, NH, NJ, OK, OR, RI, SC, SD, TN, TX, UT, VA, VT, WA, WI, WV, WY |
Platforms | IOS/Android |
Info last verified | October 12, 2026 |
PrizePicks got into the prediction markets space in November 2025 by partnering with Kalshi. They simply added a prediction markets section to the PrizePicks app (in the 33 Team Picks states and 48 Culture Picks states), and all of the event contracts are provided by Kalshi. For sports, it is called Team Picks.
So effectively, you're trading on Kalshi through the PrizePicks app. That's obviously convenient for any PrizePicks players, who receive a strong signup bonus in comparison to other prediction market apps because of it. The offer awards users with $50 in bonuses after they spend $5. However, that integration adds a layer of complication if you're not interested in playing picks lineups.
What we like
Powered by Kalshi: Because event contracts are provided by Kalshi, more liquidity and trading are happening than on other Fantasy and sportsbook apps that have jumped into the prediction market space.
Clear contract details: Unlike on some of the newer sites, PrizePicks provides very clear contract details so it's clear to see how a trade is settled.
Early payouts: Because of Kalshi's liquidity, PrizePicks often offers early payouts that are easy to process.
Good signup bonus: Because PrizePicks' regular bonus can be spent on its prediction market, the spend $5, get $50 in bonuses ends up as one of the stronger prediction market bonuses.
What could be better
Limited team picks availability: Trading on sports might not be allowed based on where you live.
Not exclusively a prediction market: If you're not already a PrizePicks app user and you're exclusively interested in prediction markets, why wouldn't you just use Kalshi instead?
What is PrizePicks Team Picks best for?
Like Underdog, if you're already a PrizePicks user, this is going to be an extremely easy transition. Even better, it's actually backed by Kalshi, which means it's peer-to-peer and doesn't suffer from the same liquidity issues as other sites. However, if you're not interested in playing PrizePicks lineups, you might be better off going to the source (Kalshi).
Novig
While Novig is not quite as recognizable as some of the other markets listed above, it has made a name for itself as one of the better up-and-coming options for those interested in sports trading.
Novig promo code | No promo code required |
Novig sign-up bonus | Deposit $10, get $25 bonus trading credits |
Available states* | Nationwide (excluding AZ, MI, and NV) |
Platforms | IOS/Android/Web |
Info last verified | October 12, 2026 |
Novig stands out as one of the newest nationwide prediction markets catered to trading sports contracts. While other apps often carry markets unrelated to sports, Novig is exclusively focused on sports, giving the app a tailored feel. Additionally, like other reputable prediction markets, Novig is regulated by the CFTC. Users can feel safe when providing details regarding their identity and financial institutions.
What we like
- Novig's interface is clean and easy to use, regardless of one's familiarity with navigating prediction markets.
- The Novig promo code offer is a solid one, keeping pace with the rewards offered by Kalshi, Polymarket, and FanDuel.
What could be better
- While other markets have a wide variety of sports options for traders, Novig's sports section is comparatively small.
- Additionally, Novig only offers sports markets, potentially disincentivizing users who might want to dabble in trading on other areas as well as sports.
What is Novig best for?
Novig is best for users who know that they are exclusively interested in trading on a small range of well-known sports. Novig cuts out everything else for that demographic, offering a focused sports-market experience that is rare among trading platforms.
How we rate prediction market sites
Given the relative newness of the prediction markets industry, prediction market apps are constantly evolving to better suit the needs of traders and the markets themselves. So you can expect sign-up bonuses and features to change pretty rapidly, but we've thoroughly evaluated the current offerings from the brands we've listed above.
Our team considered factors like market variety and depth, bonus and promo value, platform user experience (web and mobile), user safety, withdrawal options, payout speed and customer support quality. We also only review prediction market sites that are federally regulated by the CFTC.
Ultimately, we found some common threads among sites and also tried to define what sets each individual brand apart with hopes of helping you make an informed decision about which prediction market sites are right for you. We'll also frequently update these reviews as promos and features inevitably change or as yet-to-be-created platforms gain popularity.
What is a prediction market?
CFTC-regulated prediction markets offer event exchange contracts, which allow you to trade on predictions about the outcomes of designated events. These are typically Yes/No contracts with clearly defined parameters. In sports prediction markets, that usually means that you're trading on the outcome of a future event, like which team will win the game or will a player score 20 points or more.
Prediction market platforms are built as exchanges, meaning you're purchasing or selling contracts to another trader. Those other traders could be individual users or employees of financial corporations trading on their behalf. They're also probability-based in nature, so pricing is meant to correlate with a percentage likelihood of something happening. If you buy 100 shares of something at $0.60 per share, that assumes a 60% probability of a desired outcome, and those 100 shares pay out a total of $100 ($1.00) per share if you're correct.
Are prediction markets permitted in the United States?
Yes, prediction markets are generally permitted in the United States, although availability may vary by state. The most prominent prediction-market platforms available to U.S. users include Kalshi and Polymarket.
Final thoughts on prediction markets
Which prediction market is right for you is dependent upon a number of circumstances, but stability should be a primary consideration given the changing nature of the landscape. For that reason, an industry leader like Kalshi or an offering from established online gaming brands like FanDuel might make the most sense.
Availability is also worth checking first. Traders in states like Texas, for example, currently have access to most of the platforms covered here.
Regardless of your personal choice, remember to check out the latest prediction market promo codes and sign-up bonuses to maximize your trading power. This is a rapidly expanding industry with serious growth opportunities, but you have to understand how prediction markets work and the potential risk before trading.
Responsible Trading
All event contract customers must be U.S. residents and 18+. Some event contracts may not be available in every state, and event contract trading carries significant risk and is not appropriate for everyone. There is no guarantee against loss offered, and past results are not indicative of future results.
If you or someone you know has a trading problem, please seek assistance from trained professionals. Call or text 1-800-MY-RESET.
Responsible trading tools
Check your prediction market account settings for various tools. Many prediction markets offer tools like:
Trading breaks: Take a temporary pause from trading when you need to step back.
Deposit limits: Set a maximum monthly deposit amount.
Education guides: Understand the risks of trading and how to trade responsibly.
For those who want to self-exclude from prediction markets, visit selfexclude.io for ecosystem-wide self-exclusion. This will permanently remove you from being able to trade on prediction markets.
Prediction markets FAQ
What is our pick for the best prediction market site in 2026?
Kalshi is our pick as the best prediction market app. The site has a massive range of trading options available on a user-friendly, accessible interface, making it an ideal example of how prediction markets work.
How do prediction market promo codes work?
Not all prediction market sites offer promo codes, and there are a number of different sign-up bonuses available. However, the best prediction market apps generally require you to either opt in or enter a brand-specific code to collect some form of incentive. Be sure to check the fine print to ensure that you fully understand the requirements before signing up.
What's the difference between a prediction market and sports betting?
The main differences are regulatory structure and market mechanics. Prediction markets are generally regulated at the federal level by the CFTC, while sportsbooks are typically regulated by state gaming authorities. At a sportsbook, bettors wager against the operator, which sets and adjusts odds. In a prediction market, users trade contracts with other participants on an exchange, and prices fluctuate based on buying and selling activity in the market.
Event contracts trading involves a risk of substantial loss and is not suitable for all investors. Participation in prediction markets is subject to applicable eligibility requirements. Participation may be restricted or prohibited in certain jurisdictions and participants are responsible for ensuring their participation complies with applicable laws and regulations in their jurisdiction. Prediction markets content is not intended for individuals located in jurisdictions where they are prohibited.
