How to Bet on Prediction Markets

Prediction markets are becoming increasingly prominent across the United States, offering a new way for users to speculate on real-world events. Rather than placing traditional bets, traders buy and sell contracts tied to specific outcomes - from election results and economic indicators to sports championships and entertainment awards.

These platforms blur the line between investing and betting, allowing users to trade opinions on future events in real time as market sentiment shifts. But how exactly do prediction markets work, where are they available, and how do they differ from the sportsbooks most bettors already know?

Below, we break down everything you need to know - including how to sign up, how to start trading, and what makes prediction markets one of the most talked-about developments in U.S. wagering.

What Does “Betting” in Prediction Markets Mean?

Unlike a sportsbook, where you place a fixed bet, trading in prediction markets means buying and selling event contracts whose price reflects the market’s expectation of an outcome. For a binary (yes/no) contract:

• If you buy a “Yes” contract at $0.60, that implies the market believes there’s a 60% probability the event will occur.
• If the event resolves as “Yes,” your contract pays $1; if “No,” it’s worth $0.
• Likewise, you can buy “No” contracts (or short “Yes”) depending on your view.

You can enter a market early, hold until resolution, or exit by selling your position beforehand (if liquidity exists).

Because prices shift with market sentiment, you may profit (or lose) before the outcome is even decided. It works like a mini stock market for real-world events.

How to Sign Up with Prediction Market Apps

Getting started with prediction market apps is quick and easy. The process is similar across platforms, and you can be trading event contracts within minutes. Follow these simple steps to open your first account:

1. Choose Your Prediction Market Platform

The first step is to decide where you want to trade. Compare leading prediction market sites such as Kalshi and Polymarket, both of which offer user-friendly interfaces and a growing range of event-based markets. Check each platform’s product range, regulation, and available markets before signing up - so you choose one that matches your interests and trading style.

2. Create and Verify Your Account

Once you’ve selected your preferred site, it’s time to register. You can usually do this on desktop or via a mobile app. Provide a few personal details - your full name, email, home address, and date of birth - to set up your profile.

Because prediction markets are regulated similarly to financial exchanges, most operators will ask for identity verification. This may include a Social Security Number (SSN) and a photo ID (driver’s license, passport, or similar). Completing verification ensures your account is secure and compliant with U.S. regulations.

3. Claim a Welcome Offer (If Available)

Some prediction market platforms offer new-user incentives - often in the form of trading credits or fee rebates rather than traditional “bonus bets.” If there’s a promo code or welcome bonus available, be sure to enter it during registration or first deposit. While offers in this space are less common than at sportsbooks, keep an eye on each site’s promotions page for any seasonal or referral-based bonuses.

4. Make Your First Deposit

Next, add funds to your account. Head to the cashier section, choose your preferred payment method, and enter the amount you’d like to deposit. Most U.S. prediction market apps support bank transfer (ACH), debit card, or wire deposit options. Once the funds appear in your balance, you’re ready to trade.

5. Start Trading Event Contracts

Now for the exciting part - placing your first trade. Browse the available markets, decide whether you want to buy “Yes” or “No” contracts on a specific outcome, and confirm your trade.

Prices move dynamically based on demand, so you can enter, adjust, or close your positions any time before the event settles.

Prediction markets often feature political, economic, weather, or entertainment-based events, giving you far more flexibility than a typical sportsbook.

6. Manage and Withdraw Your Funds

When you’re ready to cash out, return to the cashier and select Withdraw. Enter the amount you’d like to withdraw, confirm your method, and submit your request.

Most leading platforms process withdrawals within a few hours, and funds typically land in your bank account within one business day.

Key Concepts & Strategies

To trade smartly, you need more than intuition. Here are essential concepts and tactics:

Pricing = Implied Probability

The contract price corresponds to how the market estimates the probability of an outcome. A $0.75 “Yes” contract implies a 75% chance. 

Liquidity & Spread

If few participants trade a contract, spreads may be wide, or matching your bid/ask may be hard. Low liquidity is a major risk in nascent markets.

Value / Edge

Search for mispriced contracts. If you believe the true probability is higher or lower than the market’s, that’s your opportunity.

Risk Management

• Never bet your whole balance on one outcome
• Cap your exposure to a certain percentage
• Diversify across multiple markets
• Take partial profits when possible
• Avoid emotional trades

How It Works on Kalshi

Because Kalshi is the most prominent U.S.-regulated platform, here’s how a typical trade flows:

• You open a contract (“Yes” or “No”) for a given event.
• The market price shifts in real time depending on supply and demand.
• You can exit early – selling your contract before resolution – if there is sufficient counterparty liquidity.
• At event resolution, contracts pay out $1 if correct, or $0 if wrong.

Prediction Market Sites vs. Traditional Sportsbooks

While prediction markets and sportsbooks share the same core idea - speculating on the outcome of events - the way they operate is quite different. Here’s how they compare in 2025:

• Market Structure Prediction markets revolve around straightforward Yes or No contracts. Each event has two possible outcomes, and you decide which side to take. Sportsbooks, meanwhile, offer a wider range of betting options - from moneylines and spreads to props and parlays - covering all major leagues and many niche sports.
• Variety of Markets Sportsbooks tend to feature extensive coverage of sporting events worldwide. Prediction markets focus on a more selective range of outcomes - often spanning sports, politics, finance, and current affairs. This makes them attractive to users who like the simplicity of binary outcomes, while sportsbooks appeal to those seeking more betting variety.
• How Prices Are Set At sportsbooks, odds are set by traders and algorithms that factor in data, form, and betting patterns. Prediction market prices, on the other hand, are determined by the activity of traders themselves - the balance of buyers and sellers sets the value of each contract. This peer-driven approach can lead to fluid, market-based pricing that moves in real time.
• Transparency and Market Movement Prediction markets display live prices and total trading volumes, allowing users to see how sentiment changes over time. Sportsbooks don’t typically publish detailed data about line movement or betting volume, though odds updates reflect similar underlying shifts in opinion.
• Regulation Sportsbooks are licensed at the state level, operating under local gaming commissions. Prediction markets such as Kalshi are regulated at the federal level by the Commodity Futures Trading Commission (CFTC). That difference means prediction markets can sometimes operate across multiple states, while sportsbook access depends on local laws.
• User Experience Sportsbooks offer a familiar betting experience - choose your wager, set your stake, and wait for the result. Prediction markets function more like exchanges, allowing you to buy or sell positions before an event concludes. That makes them appealing to users who like the idea of trading outcomes as probabilities change.

Which Sites Will Offer Prediction Markets in the Future?

We expect more entry & expansion in this space. Here’s what’s on the horizon:

• Major sportsbooks & fantasy/betting operators like DraftKings and FanDuel are rumored or likely to follow. The competitive pressure is increasing as prediction markets gain profile and legitimacy. (Note: as of now, no public full launch by those, but industry commentary suggests they’re watching closely.)

Where Can You Bet on Prediction Markets?

Legal States / Sites

Because much of the legality is federal (CFTC), many prediction markets claim to operate in all 50 states. For example, Kalshi states that its sports trading and election markets are legal everywhere in the U.S. under its federal regulation. 

However, in practice, there are many states where state-level regulators have issued cease‐and‐desist orders or other challenges, especially for certain sports or political markets: New Jersey, Illinois, Maryland, Montana, Nevada, Ohio are often cited. 

If you are in one of those states, particular contracts / markets may be unavailable or you may face legal uncertainty.
