Polymarket is not a bookmaker in the usual sense, but a leading prediction market. Instead of betting against the house, you trade shares of "yes/no" on real-world events: elections, economics, sports, crypto, culture. The price of a share reflects the probability of an event, and a correct prediction brings profit. The platform operates on the blockchain, settles in the stablecoin USDC, and has already attracted $2 billion in investments from the owner of the New York Stock Exchange. Let's break down how it works and how Polymarket differs from traditional betting.

What is Polymarket and a Prediction Market

A prediction market is a platform where participants buy and sell shares that reflect the probability of an event. The key difference from a bookmaker is that you are not betting against the house, but amongst yourselves, and the price is formed by the market itself in real-time.

How it works on Polymarket:

Each market is a question with a yes/no answer ("Will the Fed lower rates this quarter?")
YES and NO shares together always cost $1
A share price from $0.01 to $0.99 shows the market's assessment of the event's chance
A YES share at $0.62 means the market assesses the event's chance at ~62%
If the event happens – your share is worth $1, if not – $0

Example: you buy YES at $0.40. The event happens – you get $1 (profit $0.60). It doesn't happen – you lose your invested $0.40. The mechanism is as simple and transparent as possible.

How Polymarket Differs from Traditional Betting

The format is fundamentally different from classic betting – the difference is key:

Traditional Bookmaker: You bet against the house, they set the odds and earn from the margin. If you win, the house pays.

Polymarket: it's an exchange, not a bookmaker. You trade shares with other participants, the market sets the price, and smart contracts handle settlements. There is no competing bookmaker – there is a live market of probabilities.

What this offers:

Transparency – all trades are on the blockchain, no one can manipulate the odds
Real probabilities – the price reflects the opinions of thousands of participants, not the bookmaker's margin
You can exit at any time – sell your share before the event ends at the current price
No bookmaker limits – the market is limited only by liquidity

How Accurate is Polymarket

The platform's main advantage is its reputation as an accurate predictor. A 2025 study showed that Polymarket predictions come true in accordance with their probabilities in over 94% of cases, and even more accurate than traditional polls a month before the event occurs.

The most famous example is the 2024 US Presidential election. While national polls showed a statistical tie between candidates, Polymarket was trading Trump's contract above $0.60 back in October. Trump won. It was then that the media began to widely quote Polymarket as a source of real probabilities.

Today, the platform is monitored by media, analysts, and even politicians – it's no longer just a betting platform, but a tool for collective forecasting.

Market Categories

You can trade on events from a wide variety of spheres on Polymarket:

Politics – elections, appointments, laws, resignations
Economics – Fed rates, inflation, macro indicators
Sports – finals, championships, matches
Crypto – coin prices, regulation
Culture – awards (Oscars), events, trends
Geopolitics and World Events – major international topics

Sports section on Polymarket: betting on match outcomes, championships, and finals – share price reflects team chances.

Polymarket crypto markets: trading predictions on coin prices, regulation, and crypto events.

Polymarket political markets: elections, appointments, decisions – the platform's most famous and accurate category.

Commissions

Polymarket uses a dynamic commission model – the amount depends on the category and how close the chances are to 50/50 (commission peaks at 50/50, decreasing towards the extremes):

Category	Maximum Commission (taker)
Geopolitics and World Events	0% (free)
Sports	0.75%
Politics	1.0%
Economics	1.5%
Crypto	1.8%

An additional benefit: USDC deposits and withdrawals are commission-free from the platform. You only pay the Polygon network fee (a few cents), and Polymarket covers the withdrawal gas fee.

Payment and Access

Polymarket operates on cryptocurrency:

All settlements are in USDC (a stablecoin pegged 1:1 to the dollar)
Network – Polygon (plus Solana support)
Deposit: transfer USDC from your wallet or buy through MoonPay with a Visa/Mastercard
Funding is possible with USDC, USDT, or SOL, but all trading is conducted in USDC

Access: The international version works globally and does not require verification (KYC) for most actions – login via a crypto wallet. This is convenient for players worldwide.

Who is Behind Polymarket

The scale and trust in the platform are impressive:

Founded in 2020 by Shane Coppleman (his net worth is now estimated around $1 billion)
$10 billion in monthly turnover (first exceeded in March 2026)
Company valuation – $15-20 billion
ICE, the owner of the New York Stock Exchange, invested $2 billion and received approximately 22% of the shares – a high level of institutional trust
Investors include Peter Thiel (Founders Fund) and Vitalik Buterin (creator of Ethereum)
Recognized by TIME magazine as one of the 100 most influential companies of 2025

When a company with blockchain roots is acquired by the owner of the NYSE, it signifies that prediction markets are entering the financial mainstream.

Is Polymarket Worth Trying

Who it's for:

Those who follow politics, economics, sports, and want to "bet on their opinion"
Crypto enthusiasts – everything is in USDC, without banking barriers
Analysts – the platform provides real probabilities, not bookmaker margins
Those who value blockchain transparency and the ability to exit a position at any time

What to consider:

This is not classic betting – you need to understand the logic of YES/NO shares
The accuracy of the market depends on liquidity: on "thin" markets, the price is less reliable
It operates on crypto – you will need USDC and a crypto wallet
As with any betting, only risk what you can afford to lose

Polymarket is a unique format at the intersection of betting, trading, and collective forecasting. If you are interested not just in betting, but in trading the probabilities of real events on a transparent, global-scale blockchain platform – Polymarket is worth your attention.

Frequently Asked Questions

Is Polymarket a bookmaker or an exchange?

This is an exchange, not a bookmaker. You don't bet against the house, but trade 'yes/no' shares with other participants. The price is formed by supply and demand, and smart contracts handle the settlements. There is no opposing bookmaker setting odds here.

What does the share price on Polymarket mean?

The price reflects the market's assessment of the event's probability (from $0.01 to $0.99). The closer the price is to $1, the higher the market's assessment of the probability that the event will occur. When the event resolves, the share is worth either $1 (it happened) or $0 (it didn't happen). The difference between the purchase price and the final $1 is your profit.

Is verification (KYC) required for Polymarket?

The international version generally does not require verification for most actions – login is through a crypto wallet. This differentiates Polymarket from regulated exchanges. However, availability and requirements depend on your country.

Can I sell a share before the event ends?

Yes, this is the advantage of the exchange format. You can sell your share at any time at the current market price, without waiting for the event to resolve – for example, to lock in profits if the price has risen in your favor.

Why are Polymarket predictions considered accurate?

The share price reflects the collective opinion of thousands of participants investing real money. Studies have shown agreement with outcomes in over 94% of cases. A classic example is the US 2024 election, where Polymarket indicated the winner more accurately than polls.

In what currency are settlements conducted?

All settlements are in USDC – a stablecoin pegged 1:1 to the dollar. You can fund your balance with USDC, USDT, or SOL, but trading and payouts are in USDC. USDC deposits and withdrawals are not subject to platform fees.
