What is Polyblock?
Polyblock is a professional trading terminal for Polymarket, the world's largest prediction market. It provides advanced tools for trading crypto price prediction events with real-time data, historical charts, and sophisticated order management.
Unlike basic trading interfaces, Polyblock offers a terminal-style experience with live orderbook data, WebSocket price streaming, and deep market analysis tools. Our platform connects directly to Polymarket's CLOB (Central Limit Order Book) for lightning-fast trade execution.
Quick Overview
- •Buy and sell shares — representing crypto price prediction outcomes (e.g., "Will BTC close above $100k in the next hour?")
- •Always priced between 0.00 and 1.00 USDC.e — every pair of event outcomes (YES + NO shares) is fully collateralized by $1.00 USDC.e
- •Shares created on agreement — when opposing sides come to an agreement on odds, such that the sum equals $1.00
- •Market resolution payout — shares representing the correct outcome are paid out $1.00 USDC.e each
Understanding Prices
Prices on Polyblock represent the market's belief in the probability of an outcome. A YES share priced at $0.75 means the market thinks there's approximately a 75% chance that outcome will occur.
The orderbook shows all available buy and sell orders at different price levels, allowing you to see market depth and liquidity before placing your trade.
Making Money on Markets
There are several strategies for profitable trading on Polyblock:
Directional Trading
Buy YES or NO shares based on your prediction of the outcome. If you believe BTC will rise, buy YES on "BTC up" markets at favorable prices.
Market Making
Provide liquidity by placing both buy and sell orders. Earn the spread between bid and ask prices when both sides of your orders are filled.
Arbitrage
When YES + NO prices sum to less than $1.00, buy both sides for a guaranteed profit upon resolution. Polyblock shows spread analysis to help identify these opportunities.
