Interest in prediction markets continues to rise. The FIFA World Cup is currently driving record trading activity, and leading prediction market apps are using enhanced promotions to stand out in an increasingly competitive market.

Kalshi has joined the trend with their largest trade offer yet: a "Trade $20, Get $20" bonus that new users can now claim, giving them extra funds to trade on World Cup markets and other popular event outcomes. 

To make it easy to claim one of these leading welcome offers, we consolidated all the important bonus terms into a single table, including the best promo codes for our top prediction market apps.

The hassle-free $20 bonus is larger than the other Kalshi welcome offers and still enough to let you test their world-class prediction trading app. I also personally found the Kalshi prediction platform to be one of the most intuitive to use, with some of the deepest sports offerings in MLB, NBA, and the World Cup, whether you're on desktop or mobile.

The leading prediction market apps typically offer new users welcome offers that include small amounts of bonus money or site credit after they complete registration, and make their first trade or deposit. 

In general, prediction market promos have simple terms and can often be cleared quickly, allowing users to try event contract trading with the aid of some site credit.

This differentiates them from the welcome bonuses offered by larger sportsbooks that try to impress with big totals but are often tied to difficult terms or confusing conditions. 

Here are the most common forms of prediction market promos for event trading right now. 

🎁 Deposit matches

Deposit matches have a simple promo structure that asks you to deposit a certain amount, which will then be matched in cash or site credits. Polymarket currently has the highest-value deposit match on the market, with a 'Deposit $20+, get $50' match offer. 

↔️ Trade and get

A trade-and-get offer requires users to make a deposit and complete their first trade to unlock a bonus. While these offers do require an extra step, the rewards are often larger than those of simple deposit matches. Kalshi has a very simple trade-and-get offer, where users get $20 after completing a $20 trade. ProphetX, one of the newest prediction market platforms, also offers a similar trade-and-get offer that requires only a first trade of $10 or more. 

🪜 Laddered promos

Laddered promos are promos whose value increases as you complete certain steps or milestones. With a laddered welcome promo, a site increases the value of your offer as you complete specific tasks or stages. 

🎉 Contests

For big events such as the World Cup or Super Bowl, sites like Polymarket and Kalshi often reward new and existing users with large-scale contests offering chances at big prizes. 

Looking for more prediction platforms and promo offers? The ROLR prediction market promo code is one you'll want to check out soon, as this new prediction site now has a waitlist open for new users. 

Prediction market promos are a useful tool for anyone who wants to start trading on sports events like the World Cup or real-world events such as elections. They are almost always easy to claim and offer a helping hand on your first trade or two as you try out apps like Kalshi and other platforms.

Most traders who benefit from prediction promos will be new users trying out prediction trading for the first time, or potentially comparing new sites. However, other specific traders can benefit from prediction market promos as well, including:

• Traditional sports bettors who want to speculate on real-world events such as politics, entertainment, or finance. 
• Sports bettors who want to benefit from the no vig/low fee model of prediction markets.
• Event contract traders who want access to site-specific markets, such as politics or geopolitical event trading (war, diplomacy, etc) on Polymarket.
• Traders wanting an alternate platform for hedge trading purposes, or for trading crypto assets specifically.
• Anyone who wants to speculate on sports such as MLB or the NFL and lives in a state where sports betting is banned or limited, such as Texas, Florida, Georgia, or California.

Most people will find welcome offers and bonuses on prediction platforms and apps like Polymarket useful. However, there are those who may not find prediction promos to be much help. 

Since prediction market promos tend to be lower-valued, low-commitment bonuses, anyone seeking to unlock a larger sportsbook-style bonus in their startup may need to reconsider options. Prediction market bonuses won't provide you with a large boost in bankroll right away, and for some traders, they will hardly register at all. 

Others who not benefit from prediction market promos include:

• Those seeking regular profit boosts for trading. Prediction sites offer little for existing users in this area compared to a sportsbook.
• Anyone who prefers sportbook-style odds to the implied probabilities used in prediction markets.
• Sports bettors who would prefer not to learn about trading and would rather stick with simple sportsbook dynamics, including bookmaker-created odds.
• Bettors who only want access to specific sports and game props and aren't typically interested in speculating on areas outside of sports.

Promotions for prediction markets from leading platforms are generally considered safe and legitimate. Our top-rated prediction platforms, such as Kalshi or Polymarket, are all regulated by federal agencies, including the CFTC, and are designated contract markets.

However, it is important to note that prediction markets do function differently from sportsbooks. Instead of wagers that use odds set by a bookmaker, prediction sites offer financial derivatives in the form of binary contracts that trade event shares priced from $0 to $1 and act as "all-or-nothing" contracts.

This payout system means that if you are wrong, you lose the entire value of your trade, making prediction trading very similar to sports betting in many regards, and (overall) riskier than traditional stock investing.

How to tell if a prediction market promo is legit?

Legit prediction market promos (such as those from Polymarket or Kalshi) are usually structured as deposit matches, trade-and-get, laddered rewards, or profit boosts for regulated event contracts. These sorts of promos are often easily verified by checking the site's CFTC registration.

The best prediction market promos are legal welcome offers offered by a prediction market platform that is a federally regulated trading site under the Commodity Futures Trading Commission (CFTC).

All of our featured prediction market platforms are legitimate operators, federally regulated to operate in the US, and legal in up to 50 states (although some small state-by-state restrictions may apply). This means that residents of California, Texas, and Florida, where sports betting is not currently legal, can use prediction markets and claim our featured prediction market promos.

Most promos from legitimate prediction market sites are easy to claim and come with clear terms. However, always ensure you review the conditions before claiming.

Prediction market promos state guides

Most prediction markets are available across the United States, outside of Nevada and other select locations. However, for those users in states where sportsbooks aren't legal or regulated, you'll still able to access several prediction markets platforms and their welcome offers.

To help, we've provided state guides for users in the largest states:

The best prediction market promos differ from top sportsbook promos in several important ways, with terms and bonus allocation being key differences.

Here are the main differences to consider when claiming a prediction market app welcome promo vs. a traditional sportsbook promo.

Note: We're in the process of acquiring an Underdog promo code.

Prediction market promos expose you to speculating with higher-risk binary contracts on platforms with markets on almost everything. While the promo offers themselves are a nice starting bonus its still prudent to be mindful when claiming these offers and using prediction market sites. 

Here's my list of tips that will help you use an event contract promo responsibly from the get-go:

📜 Review the terms and conditions

Although prediction market promos are easier to claim and often have clearer terms than sportsbook bonuses, these bonuses can still include fine print that requires you to follow certain procedures closely. Do your own due diligence before you sign up.  

🏦 Only deposit what you're comfortable with

Prediction markets aren't the same as investing. They may present themselves differently from sportsbooks, but binary trading is very similar to placing a sports bet, as you can lose your entire investment on any single trade. Don’t overlook the fact that trading predictions on real-world events carries a lot of risk.

📊 Understand implied probabilities and how trading works

Since they’re not sportsbooks, prediction platforms generally display current prices as percentages that represent the implied probability of an event occurring. Make sure you understand what these percentages represent so you can better interpret price action and historical data, and make smarter trades.

👉👈 Understand the concept of peer-to-peer trading

Unlike sportsbooks, prices on prediction platforms aren’t controlled by bookmakers employed by the site. Instead, price action is driven by the collective buying and selling activity of market participants (traders). Make sure you understand how supply and demand affect the price of an outcome before investing.

💡 Develop a trading plan based on your knowledge base

Keep your world small as you start out. While it will be tempting to invest in the most trending topics, trading in areas you're familiar with will likely lead to better results, at least initially. Avoid FOMO'ing into trades at all costs.
