Introduction

On the night of November 5, 2024, something unusual happened. While TV networks and pollsters were still calling the U.S. presidential race too close to call, one corner of the internet had already made up its mind — not with opinions or punditry, but with money. Millions of traders were buying and selling shares on the election's outcome in real time, and their collective verdict pointed to the winner hours before the final results were confirmed.

That corner of the internet was Polymarket.

Polymarket is the world's largest blockchain-based prediction market — a platform where you trade "Yes" or "No" shares on the outcome of real-world events, from Bitcoin price moves and elections to sports and breaking global news. Every share trades between $0.01 and $1.00, and the price itself is the forecast: a "Yes" trading at $0.72 means the crowd puts roughly 72% odds on that outcome. No pundits, no polls — just people backing their convictions with real money, and collecting exactly $1 per share when they're right.

It sounds like a tool reserved for Wall Street quants and crypto natives. It isn't. You can access Polymarket directly inside the KuCoin App through KuCoin Web3 Wallet — no separate account, no browser extension — including fast-paced 5-minute crypto "Up or Down" markets, where you predict whether Bitcoin finishes higher or lower within the next few minutes.

This guide covers everything you need to get started: what prediction markets are, why a crowd with skin in the game is often sharper than the experts, and how to place your first Polymarket trade on KuCoin, step by step.

What Is Polymarket?

Polymarket is a prediction market platform built on the Polygon blockchain, where users buy and sell outcome shares — typically "Yes" or "No" — on the results of real-world events. Markets span crypto, sports, politics, culture, technology, macroeconomics, and global news. All trades are denominated in USDC, a stablecoin pegged 1:1 to the U.S. dollar, and settled transparently on-chain .

Shayne Coplan founded Polymarket in New York in 2020, originally as an experiment in turning public opinion into financially backed, crowd-implied forecasts . Instead of a bookmaker setting the odds, prices emerge organically from thousands of traders putting real money behind their beliefs — which is why Polymarket's odds are often cited alongside (or ahead of) traditional polls. One analysis puts Polymarket's accuracy at roughly 94% a full month before an outcome is known.

The platform's growth has been striking: over $3.5 billion in volume during the 2024 U.S. election cycle, $3.74 billion in November 2025 alone, and a $2 billion strategic investment from Intercontinental Exchange (ICE), the parent company of the New York Stock Exchange . After acquiring the CFTC-regulated exchange QCEX in 2025, Polymarket also relaunched in the United States — a sign that prediction markets are moving firmly into the financial mainstream .

How Do Prediction Markets Work?

The mechanics are simpler than most people expect. Every market asks a question with a binary outcome, and you trade shares on which side you believe is right.

Price Equals Probability

Each Yes or No share trades between $0.01 and $1.00, and one Yes share plus one No share always equals exactly $1.00 . If a "Yes" share trades at $0.72, the market collectively assigns a ~72% probability to that outcome. Prices update in real time as new information arrives and traders adjust their positions.

Winning Shares Pay $1 — Losing Shares Pay $0

When a market resolves, each winning share redeems for exactly $1.00 in USDC, while losing shares expire worthless . Buy Yes at $0.30 and you're right? You earn $0.70 per share — a 233% return. If you're wrong, you lose the $0.30 per share you paid.

You Can Exit Early

You're never locked in. Polymarket runs on a central limit order book (CLOB), similar to a stock exchange, so you can sell your position at any time before resolution — locking in profits or cutting losses as prices move .

Decentralized Resolution

Market outcomes are verified through UMA's Optimistic Oracle, a decentralized system where anyone can propose a result and anyone can dispute it, removing single-point-of-failure risk from settlement .

A quick example: A market asks, "Will Bitcoin finish above $120,000 this month?" Yes trades at $0.40. You spend $40 on 100 Yes shares. If BTC closes above $120,000, your shares pay out $100 — a $60 profit. If not, they settle at $0.

How to Trade Polymarket on KuCoin Web3 Wallet (Step-by-Step)

The whole setup takes just a few minutes. Here's the complete process, based on the official KuCoin Web3 tutorial.

Before you start, make sure you have:

The latest version of the KuCoin App installed.
A created or imported Web3 wallet in the app.
At least 20 USDC for trading (on the Polygon network).
About 1 POL for gas fees (also on Polygon) to cover on-chain actions like deposits and withdrawals.

Step 1: Prepare USDC and POL in Your KuCoin Web3 Wallet

Fund your Web3 Wallet with supported assets on Polygon. Double-check the network before confirming any transfer — sending via the wrong network can result in lost funds.

Step 2: Open Polymarket

Once your assets arrive, open the Polymarket entry inside KuCoin Web3 Wallet. The exact entry point may vary slightly depending on your app version and region.

Step 3: Add Funds to Your Polymarket Account

Deposit your available USDC into your Polymarket trading account. This step requires a small amount of POL to pay the on-chain gas fee, so keep some POL in your wallet.

Step 4: Place Your Trade

Browse markets by category, pick an event, choose Yes or No, enter your amount, and confirm. That's it — your position is live.

Once your trade is placed, you can:

View your open position and monitor price changes in real time.
Sell before resolution to lock in profit or limit losses, if liquidity is available.
Hold to settlement and claim your proceeds if your outcome wins ($1 per winning share).

How to Use Crypto Up or Down Markets (5-Minute Predictions)

If you're a crypto trader at heart, the fastest way to get a feel for prediction markets is through Crypto Up or Down markets — short-term markets on whether BTC, ETH, SOL, and other major assets finish up or down within a set window. Here's how they work, per the official KuCoin Web3 guide.

Available Time Ranges

Time Range	Pace	Best For
5 Min	Very fast	Quick scalps, high engagement
15 Min	Fast	Short-term momentum reads
1H	Moderate	Intraday traders
4H	Slower	Swing-style predictions
1D	Slowest	Daily trend views

How to Access Crypto Up or Down Markets

Open the KuCoin App.
Switch to Web3 on the top bar.
Open Polymarket.
Select Crypto.
Choose a time range — 5 Min, 15 Min, 1H, 4H, or 1D.
View active markets, sorted by trading volume.

How to Read a Market Before You Trade

Every Crypto Up or Down market page shows six key data points. Check all of them before entering:

Market name: the asset and time window (e.g., BTC, 5 minutes).
Time range: shorter windows move fast and leave little room to adjust.
Target Price: the benchmark. Finish above it, and Up wins; finish below it, and Down wins. Always read the market rules for the exact resolution source and edge cases.
Current price: the asset's live price — compare it with the Target Price to see which side is closer to winning.
Up/Down prices: the market's implied probability. If Up is priced at 60¢, one Up share costs about $0.60, pays $1 if it wins, and settles at $0 if it loses — a roughly 60% market-implied probability (not a guarantee).
Settlement time: when the outcome is determined. Short markets close quickly, so check the remaining time.

Placing the Trade

Open your chosen market → check the Target Price, current price, and settlement time → choose Up or Down → enter your amount → confirm. You can then track the position on your Polymarket Assets page, sell early if there's liquidity, or hold to settlement.

Worked example: A 5-minute BTC market shows a Target Price of $100,000, with BTC currently at $100,050. Up is priced at 55¢. You buy $55 of Up shares (100 shares). Five minutes later, BTC closes at $100,080 — above the target. Your shares pay out $100, a $45 profit (an ~82% return in five minutes). Had BTC closed below $100,000, the shares would settle at $0.

Conclusion

Polymarket has turned prediction markets into one of crypto's most compelling real-world use cases: a transparent, on-chain arena where prices reflect what informed traders actually believe will happen. With billions of dollars in monthly volume and backing from institutions like ICE, it's no longer a niche experiment — it's becoming part of mainstream market infrastructure .

And with KuCoin Web3 Wallet, getting started couldn't be simpler: fund your wallet with USDC and POL on Polygon, open Polymarket in the KuCoin App, and place your first prediction in minutes — whether that's a 5-minute Bitcoin Up or Down call or a position on the world's biggest events.
