How to Use Polymarket

What is Polymarket?

Polymarket is a decentralized prediction market platform. On this platform:

  • You can buy and sell shares representing specific future event outcomes (e.g., “Will X happen?”).

  • The share prices reflect the current market estimation of the probability of that outcome occurring.

  • If you purchase a “Yes” share at, say, $0.65 and the event resolves in your favor, each share becomes worth $1 — giving you a $0.35 profit per share.

  • Importantly: Unlike traditional betting against a house, on Polymarket you are trading with other users (peer-to-peer), and you can also sell your positions before the final outcome.

In essence, Polymarket gives you a chance to express your views on how the future will unfold — and possibly profit from being right.


Why Use Polymarket via ioPay Wallet?

Using Polymarket through your ioPay Wallet offers several notable advantages:

  • Seamless access: If you already use ioPay, you can integrate prediction-market action into your existing wallet ecosystem rather than setting up a separate account.

  • Wallet control & self-custody: You control your private keys via ioPay; your assets remain your own.

  • Lower friction: Funding your wallet with USDC and interacting with Web3 dApps becomes streamlined.

  • Strategic alignment: For IoTeX community members, this is another extension of engaging with DeFi, prediction markets, and on-chain usage beyond simple token holding.


Quick Start Guide (via ioPay)

Here’s a high-level flow to get started with Polymarket via your ioPay Wallet — refer to the full ioPay blog article for detailed steps, screenshots, and tips.

  1. Open your ioPay Wallet and ensure you have USDC (ideally on the Polygon network) ready.
  2. Navigate to the dApp browser inside ioPay (or connect your wallet via Browser) and go to Polymarket (at polymarket.com).
  3. Connect your wallet, approve the signature.
  4. Choose a market you’re interested in: use the search/filter tools to find an event.
  5. Decide your position: “Yes” or “No” on the selected outcome. The displayed price indicates the implied probability.
  6. Buy shares. If the event resolves in your favor, each share becomes worth $1. If not, they resolve to $0. You also have the option to sell your shares before resolution to lock in profit or limit loss.
  7. Manage your risk carefully: prediction markets are not just fun — they carry risk.

From the limited content of this post, I understand that you provide a platform for two players to gamble one-on-one, with the winner taking a portion of the loser’s funds. Does the platform then charge a commission? If so, is this a zero-sum game (the platform profits, the loser loses)?

ioPay just supports this DApp and doesn’t charge any fees.
