Prediction markets are growing rapidly and let you trade on the likelihood of real-world outcomes, from elections and economic data to sports, culture, and tech milestones. Contract prices reflect the marketโs collective probability of an event happening.
In this guide, we explain how buying and selling prediction market contracts works and highlight the best prediction market sites available right now - including Kalshi, Polymarket, and Robinhood.

Prediction markets are exchanges where users trade on the outcomes of a wide range of real-world events. While they may resemble betting at first glance, participants arenโt wagering against a sportsbook or house. Instead, they buy and sell contracts with other users based on how likely an event is to occur.
Each market is framed as a simple question, and users can purchase either a 'Yes' or 'No' contract depending on the outcome they believe will happen. Contract prices fluctuate as information changes and reflect the marketโs collective view of probability.
An example can be seen here:
If a 'Yes' contract for Will Candidate A win the presidential election? is trading at $0.55, the market is implying a 55% chance of that outcome.
The prediction markets industry is still in its relative infancy, but a few brands have quickly risen to the top. Here are a few of the best prediction platforms to give you a good idea of what you should be looking for:
Kalshi is a federally regulated prediction market exchange that lets users trade on real-world outcomes like elections, economic data, sports, and major news events. Because it operates under CFTC oversight, itโs often seen as the most legitimate and transparent option for U.S. users.
The platform feels more like a financial exchange than a betting site, with clear pricing, fixed payouts, and solid liquidity on major markets. While some sports contracts face state-level restrictions, Kalshi remains the go-to choice.

Crypto.com offers prediction markets as part of its broader crypto ecosystem, giving existing users an easy way to trade on event outcomes without leaving the platform. Markets typically mirror regulated event contracts and appeal to users already comfortable with crypto wallets and balances.
While not a standalone prediction market exchange, Crypto.comโs strength is convenience and ecosystem integration. Availability can vary by state, and the experience depends heavily on how much you already use the Crypto.com app.

Robinhood brings prediction markets directly into its investing app, allowing users to trade event contracts alongside stocks, ETFs, and options. This makes it one of the easiest entry points for casual users curious about prediction markets.
The experience is intentionally simple, with limited tools but low friction. While advanced traders may find it basic, Robinhood is ideal for users who want quick, straightforward access without learning a new platform.

Polymarket is a crypto-native prediction market known for its wide range of markets across politics, culture, sports, tech, and global events. Contract prices update quickly, and liquidity is often strongest on high-profile, news-driven questions.
The platform runs on blockchain infrastructure and typically uses stablecoins for trading, which means users still need some familiarity with crypto. That said, Polymarketโs fast-moving markets and depth make it especially appealing for users who want more choice and sharper pricing than many other alternatives.

One of the most enjoyable things about using the best predictions sites is just how much variety you get in terms of what you make predictions on.

Sometimes itโs just fun to sift through the various prediction markets to see some of the more unusual options. Check out these predictions for starters:
There is ongoing debate over whether prediction markets should be classified as gambling. However, many prediction market platforms currently operate legally in the U.S., largely because they are not regulated in the same way as state-licensed online sportsbooks.
Instead of requiring state-by-state gambling licenses, prediction market platforms operate under federal oversight, most notably from the Commodity Futures Trading Commission (CFTC). Because these platforms are structured as event-based financial contracts rather than traditional wagers, they typically allow users to participate at 18 years old, compared to the 21+ requirement common for regulated sports betting.
That said, the legal landscape is actively evolving. Several states (including Illinois, Maryland, Nevada, New Jersey, and Ohio) have raised objections or taken enforcement action against certain types of prediction markets, particularly sports-related event contracts. As a result, availability can vary by platform and by state, and some operators have chosen to limit or pause services in specific jurisdictions.
While there is a growing number of prediction market sites out there, they all work in a fairly similar manner. This means that youโll usually just have to take the following steps to make your predictions:
While prediction markets are still a relatively new space, the number of available platforms is growing quickly. To help you choose with confidence, we review and compare each prediction market site using a clear and consistent set of criteria focused on legality, usability, and overall value.
We only recommend prediction market platforms that are legally permitted to operate in the U.S. and, where applicable, available in your state. Each site featured on this page has been checked for regulatory standing and operational legitimacy.
A strong prediction market should offer a wide range of questions, covering areas like U.S. sports, politics, economics, pop culture, and global events. We also look for active markets with enough volume to ensure fair pricing and easy entry or exit.
Fees should be clearly explained and easy to understand. We favor platforms that outline how fees are charged upfront, with no hidden costs or confusing pricing structures.
Reliable customer support is essential. We look for platforms that offer responsive help through channels like live chat, email, or in-app support, with clear guidance when issues arise.
Users should have access to secure funding options, whether through fiat payments, crypto, or both. We also consider how quickly and smoothly withdrawals are processed once a contract settles.
A good prediction market platform should be easy to navigate, with a clean layout and intuitive tools. We also assess whether mobile apps or mobile-friendly web platforms are available for trading on the go.
Security is a top priority. We check for SSL encryption, strong account protections, and clear privacy policies to ensure user data and funds are properly safeguarded.
Prediction markets and online sportsbooks both revolve around forecasting outcomes, but they differ significantly in how prices are set, where theyโre available, and what users can trade on. For some players, prediction markets offer more flexibility and transparency, while sportsbooks still lead when it comes to familiarity and promotions.
As prediction markets continue to grow in popularity, more regulated platforms are expected to enter the market, bringing increased competition, improved features, and potentially more incentives for new users.
For now, the prediction market sites reviewed on this page offer trusted, legally compliant options for users looking to trade on a wide range of events.
Some of the most widely used prediction market platforms right now include Kalshi, Crypto.com, and Robinhood. The landscape is evolving quickly, and we regularly update this guide as new platforms and features become available.

Yes. Prediction markets involve financial risk, and there is always the possibility of losing money. Outcomes are uncertain by nature, so itโs important to use reputable platforms and only trade amounts youโre comfortable risking.
Prediction markets donโt provide guaranteed accuracy, but prices often reflect the collective view of participants. Platforms like Kalshi are well regarded for their market-driven pricing model, where probabilities are shaped by user activity rather than a traditional bookmaker.
Prediction markets involve financial risk, and outcomes are never guaranteed. In light of this, trading should always be controlled and enjoyable. Keep your activity in check by following responsible trading practices such as:
Only trade money you can afford to lose and stop when your budget is reached.
Avoid increasing trade size or frequency to recover losses.
Don't trade when stressed, tired, emotional, or under the influence.
Take breaks and avoid letting trading interfere with daily life.
Learn how contracts, pricing, fees, and settlement work before trading.
Use spending limits, account history, or self-exclusion tools where available.
