Key Points
Polymarket is a decentralized prediction market where users can trade shares on the outcomes of real-world events in areas such as politics, sports, finance, and culture.
The platform operates on the Polygon blockchain, using USDC stablecoin, and will transition to a fee-based profit model in 2026.
After restrictions in 2022, Polymarket received approval from the CFTC in December 2025 to re-enter the US market through a regulated Designated Contract Market framework.
What is Polymarket?
Polymarket is an online platform where users can trade on the outcomes of real-world events. You are not betting against a casino or sports betting platform; instead, you are trading directly with other users. You choose an outcome (typically a simple 'yes' or 'no') and buy shares based on your judgment of the likelihood of that outcome occurring.
For example, a market might ask: "Will a certain candidate win the election?" "Will Bitcoin break a certain price this month?" or "Will a certain team win the championship?" If you think the answer is 'yes', you can buy 'yes' shares; if you believe the answer is 'no', you can buy 'no' shares.
Polymarket is referred to as a 'decentralized' platform because it uses blockchain technology. This makes the platform operate more transparently without relying on traditional banks or brokers to record and settle each transaction.
To use Polymarket, most people will connect a cryptocurrency wallet (like MetaMask or Phantom), deposit USDC, and then start trading.
How is Polymarket different from regular betting?
Polymarket is closer to financial markets than a typical betting site. In regular sports betting, the bookmaker sets the odds and has an inherent advantage built into the platform; in casino games, the rules are designed to ensure the casino wins in the long run. In Polymarket, the 'price' of each outcome is primarily determined by the amount that other users are willing to pay.
The value of prediction markets lies in their aggregation of information from the public. When many users put money into a particular outcome and take on the risk, the market price becomes an approximate estimate of the probability of that outcome occurring. Simply put, if the price of 'yes' shares is $0.70, the market roughly indicates a probability of about 70% for it to happen.
Of course, markets are not perfect. They can be influenced by speculation, rumors, large trades, or breaking news. But the core idea is that prices fluctuate based on supply and demand rather than being set by a company.
How does Polymarket work?
To understand Polymarket, you can start with three main components:
How to trade
How to use blockchain and USDC
How does the platform determine the final result (settlement)?
1) Trading, order book, and prices
Polymarket uses a system similar to stock exchanges, known as a Central Limit Order Book (CLOB). You can choose to:
Place an order at your desired price and wait for others to accept your order; or
Take existing orders, i.e., accept orders that others have placed.
Most markets are of the 'yes/no' type, with share prices ranging from $0.01 to $1.00.
Here is a simple example:
You buy 'yes' shares at a price of $0.65
If the final answer is 'yes', the share's value will become $1.00
Your profit will be $1.00 - $0.65 = $0.35 (per share)
If the final answer is 'no', the value of your 'yes' shares will drop to zero
But you do not have to wait until the event is over. If the price moves favorably, you can sell early for a profit; if the market moves unfavorably, you can also sell to cut losses.
The order book shows the prices buyers are willing to pay and the prices sellers are willing to accept. As new information (breaking news, injuries, polling updates, financial reports) emerges, traders will react, and prices will fluctuate.
2) Blockchain structure
Polymarket operates on Polygon (a scaling network connected to Ethereum) and uses the stablecoin USDC as its trading currency.
Since transactions occur on-chain, they generate public records that anyone can verify. This is often seen as an advantage because it enhances transparency.
The advantages often mentioned for this architecture include:
Clear records: Transactions can be verified on the blockchain.
Reduced reliance on centralized custodians: Users can store funds in their own cryptocurrency wallets.
Immutable records: Blockchain entries can be preserved permanently.
However, it is not without flaws. Since users control their wallets, they also have to bear the security responsibility. If you lose your wallet key or are hacked, it is nearly impossible to recover your funds.
Additionally, note that blockchain transactions require paying Gas fees. Polygon's fees are typically low, but if transactions are frequent, these small costs can add up.
3) Time-divided markets
You can browse different markets based on settlement time, ranging from 5 minutes to annual markets.
For short-cycle markets (5 to 15 minutes), please exercise caution. These markets can be exciting due to the quick resolution of results, but the risks are often higher. Prices can fluctuate rapidly, making it harder for you to make calm judgments.
4) How markets settle (who determines the final answer?)
Prediction markets must have a clear method for determining the final result. Polymarket uses a system that combines data sources with manual verification, introducing an optimistic oracle from the UMA Protocol.
Here's how it works:
Proposal: After the event ends, anyone can propose a determination of the result and submit a stake (usually 750 USDC on Polymarket).
Challenge period: The system has a challenge window (about two hours) during which anyone can dispute the result by submitting an equivalent amount of collateral.
Automatic settlement: If no one challenges, the proposed settlement result will be accepted, and winning shares will be automatically paid at $1.00 each.
Dispute escalation: If someone raises a challenge, the matter will escalate to UMA's Data Validation Mechanism (DVM), where UMA token holders will vote to determine the correct result within 48-96 hours.
Final settlement: The final result is determined by majority vote, and those who vote incorrectly will face economic penalties (forfeiture).
For very clear questions (like sports scores or market closing prices), settlements are usually straightforward. For more subjective questions, the situation can be more complex, requiring a dispute resolution process.
How does Polymarket make a profit?
Transaction costs
For a long time, Polymarket was known for not charging direct trading commissions. However, even without explicit 'platform fees', traders still face costs.
In many markets, the main cost is the bid-ask spread:
The bid price is the best price offered by buyers.
The ask price is the best price expected by sellers.
If the best bid price is $0.64 and the best ask price is $0.66, then buying and immediately selling will result in a loss of about $0.02 per share. This spread is a real cost, especially noticeable for short-term trading.
Users also need to pay blockchain fees for operations such as deposits, withdrawals, or settlements. Polygon's fees are typically low but not zero.
Changes in 2026
Polymarket pivoted in 2026 from a model that relied on direct fees to a profit model based on transaction fees. This is a significant shift, indicating that the platform is beginning to focus more on generating stable revenue from user activity.
Financing, valuation, and growth
Polymarket's growth has attracted widespread attention and investment, including:
October 2025: Reportedly secured a $2 billion investment from ICE (Intercontinental Exchange Group, parent company of NYSE), with a valuation reaching $9 billion.
January 2026: Reportedly the secondary market valuation was approximately $11.6 billion.
March 2026: Reportedly early financing discussions valued at about $20 billion.
If these numbers are accurate, they confirm how quickly prediction markets have entered the mainstream. The same report also pointed out that as Polymarket matures, it may consider going public.
Additionally, the sports market has become particularly important, accounting for about 39% of trading activity. The total trading volume for the 2026 Super Bowl-related markets was about $795 million.
Is Polymarket safe?
"Safety" can cover different aspects: Is it a scam? Can you make a profit? Will it be hacked? Is it legal? Can you protect your account?
Transparency and past records
Polymarket's trading records are on-chain, allowing independent verification of whether the market settles correctly and whether payments are made as promised.
Since its launch, the platform has processed billions of dollars in trading volume and has settled thousands of markets, establishing a good record of respecting market rules and distributing rewards.
Security risks
Polymarket is built on Smart Contracts, which may have vulnerabilities. Projects are typically audited, but this does not guarantee absolute safety.
Another major risk is wallet security. If you use a self-custody wallet, you will have complete control over your assets. This autonomy is powerful but also comes with risks:
If you lose your recovery phrase, you may permanently lose your funds.
If your device is compromised or you sign a malicious transaction, your wallet may be emptied.
Regulation
Polymarket had a dispute with the CFTC in 2022 and was fined $1.4 million for failing to register properly. In December 2025, Polymarket was approved to re-enter the U.S. market through a regulated Designated Contract Market (DCM) structure (Polymarket US operates through QCX LLC).
Outside the U.S., regulations vary significantly. In some countries/regions, prediction markets may be restricted or exist in a legally ambiguous gray area. Users should check local laws and regulations before participating.
Objective views
To date, Polymarket's operation aligns with its claims: people trade, the market settles, and winners receive profits as per the rules. However, you should still be aware of the following risks:
Smart contract issues
Wallet security mistakes
Changes in law and enforcement
Risk of manipulation by large traders
Less consumer protection compared to traditional finance
Conclusion
Polymarket is one of the most popular cryptocurrency prediction markets, enabling people to trade on real events in a C2C manner. By using Polygon and USDC, it aims to keep transactions fast, low-cost, and maintain stability in dollar valuation, while retaining a transparent on-chain record.
But it is not without risks. Anyone using Polymarket should understand how prediction markets work, protect their wallets, and closely monitor local regulatory requirements.
