After trying all the top bonuses, Kalshi is my top prediction market platform, with a trade $25, get $35 welcome bonus. To earn this bonus, simply enter promo code SBR35.

Even though some competing brands have higher bonuses, Kalshi's is among the easiest to claim, and their prediction market platform is my favorite of the bunch.

Top prediction market promos reviewed and explained

Nearly all prediction market apps offer new-user promos. Here are my favorite welcome offers right now.

Kalshi: Most available markets

Kalshi has been my go-to prediction market app since its 2021 launch. The platform offers everything from popular sports to niche events in politics and pop culture, and you can use Kalshi in many states where sportsbooks still aren't regulated.

I particularly love Kalshi’s Predictive Insights feature, which provides data-driven probabilities for various events, making it especially useful if you’re looking to go beyond casual trading and make highly informed predictions.

As for the welcome offer, you get $35 in bonuses after making a deposit of at least $10 and trading at least $25 in event contracts. You must enter SBR's Kalshi promo code SBR35 during registration to earn your bonus funds.

The Kalshi promo code is available in all 50 states + DC (excluding Nevada and Washington). You can even use Kalshi in California, the country's most populous state. Read my Kalshi review for more information. And for a direct comparison between Kalshi and Polymarket, check out my Kalshi vs. Polymarket breakdown. Or, if you'd rather try an alternative, check out other apps like Kalshi.

Polymarket: Best overall prediction market app

Getting $25 in bonus funds just for making a deposit of $10+ and inputting the Polymarket promo code SBR provides unrivaled value.

While the bonus is excellent, my favorite feature of Polymarket is its infrastructure. The platform runs on the Polygon blockchain and uses USDC for all transactions. Fees are close to negligible, and there’s no standard trading fee, with only a 0.01% fixed charge on taker orders.

While Polymarket isn’t particularly bonus-heavy, it offers Liquidity Rewards that reward users who provide liquidity and keep certain markets active. Polymarket is also offering 40% off all trading fees on football markets (college and professional) for the entire month of October. That's a nice bonus for some of the platform's most popular sporting markets. 

The platform provides deep market coverage, especially in politics, global affairs, and other non-sports markets. You also won't find any trading size limits, which gives experienced traders more room to operate.

FanDuel Predicts: Best for beginners

FanDuel Predicts is a brand-new prediction market offering from one of the most trusted names in the business. With decades of experience running online fantasy sports and online sportsbooks, FanDuel brings a wealth of know-how to the prediction market game. 

New users in select states can grab a terrific welcome bonus: Trade $5, and get $100 in Predicts Bonuses. This promo comes as five daily $20 bonuses that you earn for trading $1 or more every day after you create your account, for five straight days. You won't need a FanDuel Predicts promo code to get started, either. 

The only downside? This bonus is only available in 18 states, which are notably all states where the FanDuel Sportsbook is not legally available: AK, AL, CA, DE, FL, GA, HI, ID, MN, ND, NE, NM, OK, RI, SC, SD, TX, and UT.

ProphetX: Great for sports

I've always enjoyed ProphetX, but now that it has transitioned from a DFS platform to a prediction market app, it's officially one of my favorite platforms.

ProphetX is available in all 50 states + DC (excluding Nevada). It has a great welcome bonus, and I was able to trade $50 and get $75 after using the ProphetX promo code SBR.

The platform currently focuses exclusively on sports markets, with NFL, NBA, college football, golf, tennis, and MLB all available. This puts the platform behind others that offer markets for politics, pop culture, weather, crypto, and more. However, with a full focus on sports markets, ProphetX is one of the best NFL prediction market sites.

Novig: Best low-risk, high-reward promo

Novig is offically a full-fledged prediction market platform. New users can enter the Novig promo code SBRBONUS, then deposit $10 to earn $50 in Trade Credits. No trading is required.

Your bonus funds can be used on any available markets. Unfortunately, only sports markets are available at this time, as Novig doesn't offer pop culture or financial markets at this time.

Though there aren't any available markets outside of sports, plenty of sports markets are available, including game lines, player props, and even parlays. The $50 you earn for signing up is more than you'll get from almost every other prediction market app, and I recommend using it to get familiar with the platform before risking your own cash.

Underdog: Best for mobile users

Use the Underdog promo code SBRBONUS, and you'll be eligible for multiple welcome bonuses.

My favorite is the Play $10, Get $50 promo. You'll receive 5 $10 entries to DFS contests, and any winnings you earn, you get to keep. If that bonus doesn't appeal to you, then you can grab a 50% deposit match up to $1,000*. To max out this bonus, you'll need to deposit at least $2,000. While this is a steep price, getting $1,000 in bonus funds is no joke. No other prediction market platform offers more than $200.

And finally, there is a Rips Pack bonus, which grants you 5 free Rips worth up to $750.

No matter which bonus you choose, you can also play a game called Keep Your Million. After registering, you can join the game and be awarded $1 million. You'll then be tasked with answering 20 player prop questions. Every time you get an answer right, you keep your wager. If you're wrong, you lose your money. If you have any money left over after 20 questions, then you'll be awarded bonus funds equal to the amount you have left.

*Max. deposit match offer is 25% up to $250 in the following states: CT, HI, ID, IA, LA, ME, MT, WA

Gemini Predictions: Best for cryptocurrency exchange integration

You won't need a Gemini Predictions promo code to earn up to $100 in Predict Cash thanks to the platform's welcome bonus. Just register, deposit, and make a first trade. Gemini will match your first trade at 50%, with up to $100 in Predict Cash. 

One of the key benefits of using Gemini Predictions is its integration with the Gemini exchange. This means that if you already have a Gemini account, you won't have to download a new app, and all trades can be made within the same familiar platform. There are also no trade caps. Available markets include sports, pop culture, politics, and more.

OG: Best for live sports trading

OG is offering a $50 welcome bonus to new customers who deposit and trade at least $25. It's that simple. I was awarded $25 in bonus funds immediately after meeting the trade requirements, then received the next $25 one week later. No OG promo code is necessary.

In my opinion, this is one of the most valuable promos in the industry. While some operators provide more bonus funds, you often have to deposit and trade more to max out those bonuses. With just a $25 point of entry, OG provides one of the lowest trade limits to reach a welcome offer's full potential.

Only trades using your cash balance count towards the bonus, so you can't use any bonus funds to trade and try to collect more bonuses.

Plus500: Best for Financial Experts

Plus500 might be a new as a prediction market platform, but the company itself has been around much longer. As an investment and stock trading app, Plus500 has more than 33 million global users and trades on the London Stock Exchange as a public company. In short, this isn't some fly-by-night operator trying to cash in on prediction markets. No, Plus500 is the real deal. 

It has partnered with Kalshi to provide even contracts, which are cleared through Kalshi Klear LLC. With the backing of one of the biggest names in the business, Plus500 is a strong contender for anyone looking to branch out and try new prediction market apps. It's also a great place to start for anyone already familiar with mobile apps for investing or making online financial trades. 

New customers can use the Plus500 promo code SBRBONUS to claim a solid welcome bonus: Trade $10, Get $20 in Bonus Funds. 

Crypto.com: Best for cryptocurrencies

Unlike the other promos on this page, Crypto.com doesn't offer a standard welcome bonus. Instead, it offers $50 in bonuses for signing up and referring friends to the platform. While I didn't need a Crypto.com promo code, I found grabbing this bonus a bit tedious, even though it offers more than other competing bonuses.

Once you join Crypto.com, you'll have plenty of markets to choose from, including the MLB, PGA Tour, and MMA action. Where Crypto.com really separates itself from the competition is in the number of available cryptocurrencies for purchase and redemption.

In all, there are over 400 cryptocurrencies and fiat options supported at Crypto.com, making it one of the most easily accessible platforms in the industry.

Moon Predicts: Best for Rake Back

Moon is a relative newcomer on the prediction scene, offering a unique way to trade using its leverage multiplier. Unfortunately, markets remain limited to crypto, select stocks, and a handful of commodities and forex options. 

The Moon desktop site is really polished and easy to navigate, but there are no dedicated mobile apps yet, putting the company a step behind the competition. There are no fiat banking options yet, either, so the site is best suited to customers who are comfortable using cryptocurrencies. 

Use the Moon promo code SBR will earn you a 3.5% Rake Back welcome bonus, refunding a portion of any trading fees you end up paying. 

Onyx: Newest prediction market

Onyx Predictions is a brand-new prediction market platform that recently launched in nine states: AL, CA, CO, ID, IN, LA, ME, NJ, and WV.

As a CFTC-licensed trading platform, Onyx offers markets for sports, finance, tech, and more. Currently, new customers can snag a welcome bonus with the Onyx promo code SBR, which is 'Spend $10, Get $50'.

You can use the Bonus Funds to trade event contracts on Onyx Predictions markets. However, if you're not in one of the nine states listed above, you'll probably see the Onyx Odds daily fantasy sports (DFS) bonus instead.

Other prediction market platforms

While I've highlighted SBR's top prediction market promos, I also recommend checking out the Coinbase promo code, Robinhood promo code, Sleeper Markets promo code, Fanatics Markets promo code, or ROLR prediction market promo code.

How I rate and review prediction market promos

Here’s a detailed breakdown of how I determine the best prediction market promos:

• Bonus value: The overall value of the bonus is very important, but this isn't the only thing to consider. Still, $100 is more than $20, and that matters.
• Spending/Trading requirements: Aside from the bonus value, the next important factor to consider is deposit or trading requirements. For example, a $50 bonus that only requires you to trade $10+ might actually be better than a $100 bonus that requires you to trade $100 or more.
• Market depth: A good registration promo is only meaningful if the platform gives you a diverse range of markets to use it on. I evaluate coverage across sports, politics, finance, and real-world events to see if you have enough trading options.
• Platform fees: Expenses matter more than bonuses, so I always emphasize the total cost of participation over any single promotional perk.
• Banking structure and trading limits: Deposit and withdrawal flexibility, speed, supported currencies, and trading caps are all considered.
• UX and beginner-friendliness: I assess how intuitive the platform is from sign-up through trade execution, ensuring newcomers can take full advantage of promos and features without getting lost.
• Customer support: Although rare, sometimes I encounter small hurdles that require reaching out to a customer support team. Platforms with live chat and other communication methods that provide fast and effective resolutions get top marks.
• Mobile apps: It's 2026. Almost everyone is doing their research, banking, and trading on smartphones. Prediction market bonuses with the best mobile apps, which consider factors such as stability, speed, and ease of use, are ranked higher.

How prediction market promos differ from sportsbook bonuses

After acquiring dozens of prediction market and sportsbook promos, I've noticed numerous differences between the two.

On prediction market apps, you generally won't see typical odds boosts or bonus bets. Nearly all prediction market promos require placing a deposit and making an initial trade. Platforms like Polymarket even offer incentives for providing liquidity and keeping markets active, which doesn’t exist in a sportsbook setting.

Another distinction lies in market eligibility. Sportsbook bonuses are sometimes tied to specific markets or events, with additional terms like minimum odds requirements and rollover. In contrast, prediction market bonuses are often applied to all markets without any demanding wagering requirements.

Trading mechanics matter as well. Many of the prediction market app promos I used required me to actively trade or maintain positions rather than simply placing a single wager. This aligns the promo with the platform’s goal of encouraging engagement and liquidity, making the reward more about learning and participating than chasing a one-off payout.

That said, prediction market promos tend to be smaller at face value and usually apply to smaller beginner trades. While a sportsbook like BetMGM covers your first wager losses up to $1,500 in bonus bets, most prediction market bonuses have a much lower maximum value.

You can really get a sense of the differences between prediction market promos and sportsbook promos, by using an app like Kalshi in New York, where prediction markets and sportsbooks both legally operate.

Are prediction market promos legal?

Short answer: Yes, prediction markets and any promotions they offer are legal in most U.S. states. 

Most U.S.-based prediction markets are CFTC-approved, adding an extra layer of regulatory oversight and helping ensure fair play. Promo availability often depends on user location, though traders can use Kalshi in Texas and other states where sportsbooks are illegal.

The best way to determine a bonus's legitimacy is to check that the platform has provided details on promo eligibility, minimum deposit, trade limits, maximum bonus, expiration dates, and more.

I also recommend looking into a platform's reputation. Established names like Kalshi, Polymarket, and Fanatics are widely recognized for compliance and operational reliability. They also offer clear settlement rules, so you always know how your trades and rewards are calculated and paid out.

That said, even some lesser-known and newer platforms offer great promos.

Understanding the value of prediction market promos

Don't just chase the headline number of a promo. $25 might look better than $10, but that’s only part of the picture. It’s important to consider how easy the promo is to claim, whether it comes with restrictive conditions, if certain markets are excluded, and how fees and platform mechanics affect the overall benefit.

Many prediction markets require a certain deposit amount or even that you make a certain number of trades (usually $10 or $20) before awarding you any bonus funds. Keep these requirements in mind when judging how lucrative a potential bonus is (or isn't). 

I've found that the best value comes from a platform that's easy to use, offers good liquidity across markets, and keeps costs low. The promo simply adds a little extra incentive to get started. 

Prediction market promos and market liquidity

Even if a promo comes with no market restrictions, it won’t be very useful unless there’s sufficient liquidity to keep trades flowing.

I've had no issues using promos in high-liquidity markets, where trades are executed quickly, prices are adjusted smoothly, and promo credits can be used effectively to enter and exit positions without unexpected slippage.

However, low-volume markets are a different story. When trying to use my promo for a low-volume market, I've been limited in how much I can trade, with some trades remaining dormant for a long time (if they fill at all), making it harder to capitalize on the promotion. In general, Kalshi and Polymarket have the most liquidity in the most markets, as the two platforms with the largest user bases. 

Choosing a platform based on promo structure

I recommend that you don't solely base your decision to sign up with a platform on its registration bonus. While welcome promos are a great way to get traders in the door, available markets, trade volume, regulatory standards, available banking methods, and more should all factor into your registration decision.

To choose the best prediction platform for you, check out the best prediction market apps and learn more about all that they have to offer.

Who prediction market promos are best for

Since the prediction market industry is still relatively new, most platforms use promos to target beginners. If you’re new, they will provide you with a low-risk way to test the waters, learn trading mechanics, and experiment without putting too much of your own money on the line.

The promo credits can also be effectively used to hedge (take an opposing position on an outcome) and offset risks or to explore alternative markets that might otherwise be avoided.

But prediction market apps aren't only for beginners. Since online sports betting became legal in the US, I've used apps like bet365, FanDuel, and BetMGM to place wagers. The transition from these platforms to Kalshi and Polymarket has been seamless. And as someone interested in entertainment and pop culture, I love being able to trade on the Oscars, Grammys, and more.

When prediction market promos may fall short

Prediction market promos can be a great way to get started, but probability-based trading can feel tricky for beginners, and if you're not careful, you can quickly see your bonus funds disappear.

Prediction market promos also aren't really designed for serious traders chasing large payouts. The bonuses are relatively small and won’t make a meaningful impact on high-stakes positions.

Additionally, some promos may come with market-specific constraints, limiting which contracts you can trade or how much bonus credit you can use at once. 

How to use a prediction market promo responsibly

Prediction market bonuses are primarily designed to help you explore a given platform, so treat them as learning tools rather than guaranteed profit.

Bonus or no bonus, understanding probabilities and pricing mechanics is essential before you jump into the prediction market game. Every contract reflects the market’s current estimate of an event’s likelihood, and prices fluctuate in real time as others make trades. Therefore, always take the time to learn how positions gain or lose value before committing your bonus funds.

I recommend that you also avoid overspending your promo on high-risk trades to maximize it. It’s much smarter to use it on small trades across different markets to test strategies and learn the nature of liquidity, fees, settlement rules, and other mechanics.

Remember, whether you consider it financial trading or plain ol' gambling (the jury is still out, in many states), there is a very real risk of losing your money.

If you think your prediction market spending is getting out of control, please call the national helpline at 1-800-MYRESET or 1-800-GAMBLER.
