What is Polymarket, and is it legal?

Polymarket is a decentralized prediction market that allows users to trade on real-world events using cryptocurrency. Founded in 2020 by Shayne Coplan, the platform was built on the Polygon blockchain to make information markets accessible.

Users trade “Yes” or “No” shares on the likelihood of future outcomes in a variety of markets. After gaining traction following its debut, Polymarket exited the US market in 2022 after reaching a settlement with the CFTC on the offering of unregulated financial products. 

Polymarket continued operating globally, emerging as the world’s largest prediction market platform. In 2025, the company acquired QCEX, a CFTC-registered exchange, and subsequently announced plans to return to the US.     

Latest news on Polymarket’s growth & market expansion

Since its debut, Polymarket has grown into one of the largest and most liquid prediction markets in the world. The company’s early traction was derailed in 2022. It was forced to exit the US over allegations it was operating an unregistered derivatives trading platform

Polymarket has been operating globally since then, soaring in usage, with volume reportedly over $3 billion in October 2025 alone. The company continues to prepare for a US relaunch, receiving a green light from the CFTC following its acquisition of a registered exchange. 

It’s currently in beta mode in the US, with the full relaunch expected to happen soon. Often viewed as the global leader in the prediction market space, Polymarket will face stiff competition from Kalshi, which has emerged as the dominant US platform. 

How Polymarket works

Polymarket is a decentralized prediction market that lets users trade on the outcome of real-world events. Each market centers on a topic that will be resolved in he future. Examples of markets available for trading include: 

• Fed decision in December? 
• What price will Bitcoin hit in November? 
• Republican presidential nominee 2028? 
• Heisman Trophy winner?  

Each contract is priced between $0.01 and $0.99, reflecting the collective probability that the event will occur. For example: 

• A “Yes” share priced at $0.72 signals a 72% market belief that the event will happen.
• A “No” share priced at $0.28 implies a 28% belief that it won’t.

When the event resolves, winning shares are paid out at $1 each, while losing shares settle at $0. The difference between your purchase price and payout determines your profit or loss. Consider the following scenario: 

• You buy 100 “Yes” shares on “Bitcoin above $100,000 by December” at $0.45, for a total of $45.
• If the event resolves in your favor, your payout is $100. Your profit is $55, less fees. 
• If Bitcoin fails to hit that mark, your contract expires worthless. You’re out $45. 

Learn: How prediction markets work

Markets are resolved by independent on-chain oracles, which verify outcomes using publicly available data. You can enter or exit positions at any time before resolution, buying or selling shares based on how market sentiment shifts. 

Polymarket’s decentralized model means pricing adjusts dynamically according to user demand rather than a central exchange operator. Open access and transparency have helped make it a standout option and a global leader in prediction market trading.

• Polymarket supports global access and crypto-based trading, while PredictIt is limited to US political markets with tighter constraints.

What others are saying about the app

While reviewing Polymarket, we checked out the feedback across major review hubs. We found a mixed bag. On TrustPilot, it has a poor rating of 1.3. Common complaints include price moves based on “whale” trades, while a handful alleged they were trading against bots. 

On the App Store, the platform has a much more favorable rating of 4.8, while it currently stands at 2.8 on Google Play. Positive reviewers touted the depth of markets and ease of use, while several complaints centered on the crypto-only banking options.  

Polymarket does make it crystal clear that it’s a crypto-focused environment. Our experience aligned more with the iOS reviewers. During our test runs, we had a seamless and hassle-free experience. Polymarket deserves solid marks for its iOS and Android apps. 

Polymarket deposit and withdrawal options 

Polymarket is a crypto-only platform. All deposits and withdrawals are handled in USDC. To fund your account, you connect a compatible crypto wallet and transfer USDC on a supported network. Deposits are processed instantly on Polygon or other supported networks. 

Withdrawals are equally fast, with users able to move USDC back to their wallets on the same network they deposited from. Polymarket does not charge fees, but standard blockchain network fees may apply. Timing varies based on network congestion, but is generally fast.

While reviewing Polymarket, we found a mixed bag of feedback from users. Some reviewers had positive customer support experiences, while others were unhappy with both wait times and the helpfulness of the answers they received. 

During our own test, we used the chat feature and received an answer within minutes. We also found the help center to be informative and useful. While we had a positive experience, numerous negative reviews suggest Polymarket has lots of room for improvement.   

Who is Polymarket best for?

Polymarket is a great fit for traders who are comfortable using cryptocurrency. It’s especially appealing to users who value decentralization, low fees, and the ability to trade global events with deep liquidity. Data-driven traders will feel right at home on the platform.

It’s not the best match for beginners who prefer traditional banking or anyone unfamiliar with blockchain transactions. For those used to fixed odds environments or trading in other financial markets, know that there is a learning curve when getting started with prediction markets. 

Final rating 4.5 out of 5.0

Polymarket has become one of the most influential prediction market platforms in the world. Its decentralized structure and deep liquidity have made it a hit. It’s a great fit for users who want speed, transparent trading, a wide range of markets, and global access. 

The platform brings plenty to the table, and there should be more to come as its re-entry to the US market continues to play out. Our rating could rise even further as the platform continues to refine its user experience.

• Banking: If you only want to deal with crypto, you’ll be right at home here. Those who want the additional flexibility of leaning on traditional banking methods as needed will have to wait and see if any new options will be added.  
• Support: Common customer complaints on major review platforms center around customer support, both helpfulness and wait times. Polymarket could benefit from a greater focus on improving the customer experience here. 
• Data: The platform’s “breaking” section provides real insight into the biggest market movers, which is notably lacking at some competitors. Adding some additional simple volume tallies without the need for excessive filtering would help it stand out even more. 

Prediction markets continue to evolve quickly. Polymarket has positioned itself as one of the clear leaders in the space. Whether you’re an experienced trader or completely new to the game, it’s more than deserving of a spot in your lineup. 

FAQs

Can I withdraw my winnings to a bank account?

Indirectly. You withdraw USDC to your wallet, then use an exchange or off-ramp service to convert it to fiat. Polymarket itself does not handle bank withdrawals.

How does Polymarket determine market outcomes?

Outcomes are resolved through independent oracles and verified third-party data sources. Once resolved, winning shares pay out $1 and losing shares settle at $0.

Do I need crypto experience to use Polymarket?

Some, as you’ll need to understand how wallets work and be comfortable with transferring. New users may need a brief learning period before trading comfortably.

Is Polymarket good for beginners?

It can be, but only if you’re comfortable with crypto basics. For those new to wallets or stablecoins, Kalshi or another regulated platform may feel more familiar.

Can I cancel a trade after submitting it?

No. Once a trade executes on-chain, it’s final. You can exit by selling your shares before the market settles.

Can Polymarket markets be manipulated?

Large trades can move prices in low-liquidity markets, but outcomes cannot be manipulated. All contracts settle based on independent, verifiable data sources, not trader activity. Price swings reflect supply and demand, while settlement is locked to official results.

Does Polymarket limit how much I can trade?

There are no fixed position caps for most Polymarket markets. Your limits depend on available liquidity and how much USDC you choose to risk. High-volume markets can support large positions, while smaller markets may require more cautious sizing.
