Best Prediction Market Promos for August 2026

Which prediction market app has the best promo?

I've tried them all and can honestly say that Kalshi has the best prediction market welcome bonus. While how much you ultimately receive is random, you can max out the bonus at $500 with just $25 worth of trades (although it can be as low as $15). Polymarket requires just a $10 deposit, but the bonus maxes out at $20. 

What are the best prediction market promos?

As I see it, the best prediction market promos right now come from Polymarket, Kalshi, ProphetX, OG, and Crypto.com. Here's an overview of the different welcome bonuses available from these industry leaders, how they compare, and how you can claim them today:

Top prediction market promos reviewed and explained

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

Kalshi: Most available markets

Kalshi has been my go-to prediction market app since its 2021 launch. The platform features everything from popular sports to niche events related to politics and pop culture, and you can use Kalshi in Georgia and other states where sportsbooks are still not 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 up to $500 in bonuses after making a deposit of at least $10 and trading at least $25 in event contracts. You must enter SBR's exclusive Kalshi promo code SBR 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, take a look at other apps like Kalshi.

It's worth noting that Michigan ordered Kalshi to cease offering sports event contracts by Aug. 12, 2026. However, the CFTC ordered Kalshi to keep offering them, stating that the state doesn't have the authority to make such a demand. I will continue to provide updates as this develops.

Polymarket: Best overall prediction market app

Getting $20 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 does offer something called Liquidity Rewards, which rewards users who provide liquidity and keep certain markets active.

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.

ProphetX: Newest prediction market

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 $10 and get $20 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, there are plenty of sports markets available, and I expect ProphetX to add more cultural markets in the coming weeks. 

I'm not a huge fan of ProphetX still using a dual-currency model (Prophet Points vs. Prophet Cash), which dates back to its days as a sweepstakes platform. This makes it so you have to pay a little extra attention to ensure you know exactly what you're buying when you spend your money. 

OG: Best for live sports trading

OG is offering a $10 welcome bonus to new customers who deposit and trade at least $10. It's that simple. I was awarded the $10 in bonus funds immediately after meeting the trading requirements. 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 $10 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.

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 did find acquiring this bonus a bit tedious, even if the value is higher than many other platforms offer.

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.

DraftKings Predicts - Best welcome bonus

After years of running a highly successful sportsbook, fantasy sports platform, and online casino, DraftKings jumped onto the prediction market bandwagon in late 2025 with its own dedicated app called DraftKings Predictions. The product is fully regulated by the CFTC and is currently available in 48 states.

The overall user experience is polished with a clean and intuitive interface that doesn’t feel too data-heavy, making it an ideal spot for beginner traders. The app covers both sports-related contracts and real-world events, although the overall market variety isn’t as deep as what you'll find at other established prediction platforms. 

By unlocking the DraftKings Predictions promo code, new users will be rewarded with a "Spend $5, Get $200 in Predictions Dollars" welcome offer. This is a much larger bonus than you'll find at other prediction market apps, and with a $5 minimum deposit, it's very accessible for new traders.

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 plays a big part in how I judge it, but it's not 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 to trade execution, ensuring that newcomers can take full advantage of the promos and features without getting lost.
• 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 won’t see typical odds boosts or bonus bets, and 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 is something that simply 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, usually applicable to smaller beginner trades. While a sportsbook like BetMGM covers your first wager losses up to $1,500 in bonus bets, the best you can hope for at trading platforms is $150. While Kalshi offers up to $500 in bonuses, I've yet to meet anyone who earned that amount.

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, which provides an extra layer of regulatory oversight and helps ensure fair play. Promo availability often depends on user location, though traders can use Kalshi in Texas and other states where sportsbooks are illegal. Additionally, I've used Kalshi in Florida, where Hard Rock Bet is the only sportsbook that can operate legally.

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, DraftKings, 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.

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.

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.

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. Ever since online sports betting became legal in the US, I've been using apps like DraftKings, FanDuel, and BetMGM to make wagers. The transition from these platforms to Kalshi, Polymarket, and OG 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 aren’t perfect for everyone. Sure, they 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 easily see your bonus funds go down the drain.

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.
