#Polymarket百U战神挑战 The following is a core summary of the Gate Polymarket beginner tutorial:

· Product positioning: Gate Exchange's first entry point integrating Polymarket prediction markets, supporting "Yes/No" prediction trading on real-world events (sports, cryptocurrency prices, politics, etc.).
· Access method: Only available on the Gate App (v8.15+), via: Market → Alpha Predictions, or the Polymarket section on the homepage.
· Two participation modes:
1. Gate account login (recommended for beginners): Direct spot USDT trading, no on-chain operations.
2. Web3 wallet login: Using USDC on the Polygon network, suitable for users familiar with on-chain operations.
· Core mechanism: Buy shares of Yes (event occurs) or No (event does not occur). The price represents the market probability (e.g., Yes=0.65 USDT means a 65% chance). After the result is confirmed, the correct shares settle at 1 USDT, and incorrect shares become zero.
· Two interaction modes:
· Prediction mode: Displays probability + odds, supports quick purchase on the list page.
· Trading mode: Offers order book, candlestick charts, limit/market orders, suitable for professional users.
· Order placement rules: Amount ≥ 1 USDT and shares ≥ 5. Market orders may partially fill due to slippage protection, with remaining funds automatically refunded.
· Position management: View holdings and profit/loss on the "Positions" page, supports market/limit/share selling. May be unable to sell if the market is closed or liquidity is insufficient.
· Settlement process: After the event ends and is confirmed by the UMA oracle (2-hour challenge period), the correct position shows a "Claim" button, and earnings are automatically transferred to the spot account or on-chain wallet.
