What Is Polymarket Betting: A Practical Overview
Polymarket betting is trading outcome shares on a decentralized prediction-market exchange where each outcome token pays $1 if it resolves YES and $0 if NO. Traders buy and sell binary or multi-outcome shares on a Central Limit Order Book using pUSD. Pricing reflects market probability: for binaries, YES and NO prices sum to about $1.00. PolyArb automates intra-market arbitrage on Polymarket and offers faster fills, Telegram/Discord alerts, and a $7.62 minimum guaranteed edge per trade.
How Polymarket betting works
Polymarket runs on Polygon and uses Gnosis's Conditional Token Framework to mint outcome tokens; each outcome is an ERC-1155 token. You trade those tokens on a Central Limit Order Book (CLOB) priced in pUSD. Gas is sponsored by Polymarket's Relayer so end users don't pay gas for typical actions like placing orders or splitting and merging complete sets.
Markets are either binary (YES/NO) or multi-outcome. At fair value the sum of binary prices equals $1.00; for multi-outcome markets the sum across all outcomes is $1.00. The WebSocket and REST APIs expose order books, trades, and midpoints for programmatic access.
What bettors and traders should know
Polymarket displays best bid and best ask prices; spreads and tick size (usually $0.01, tightening near price extremes) determine execution cost and slippage. Fees vary by category and can be up to 1.8% for takers; maker fees are zero. Resolution is handled by the UMA optimistic oracle, which introduces dispute windows and timing risk before final settlement.
Geographic restrictions apply: several countries are blocked from new orders and some regions are close-only. Do not attempt VPN bypass — that violates Polymarket's Terms of Service.
Where PolyArb fits in
PolyArb is a non-custodial arbitrage bot built to capture intra-market opportunities on Polymarket. It monitors best-ask combinations and executes buy-complete-set strategies when the sum of best asks is below $1.00, locking in the difference subject to execution and settlement risks. PolyArb runs at 40ms latency versus ~800ms for common free bots, includes Telegram and Discord alerts, and is live today for $99/month.
PolyArb advertises a $7.62 minimum guaranteed edge per trade; users should still consider resolution, slippage, fees, and smart-contract risks when evaluating performance.
How this affects your approach
For a trader, Polymarket betting is both a source of speculative exposure to event probabilities and a venue for statistical arbitrage. If you focus on intra-market arb, you prioritize speed, fill quality, and reliable fee accounting. If you prefer directional positions, you focus on liquidity, news, and timing relative to resolution.
If you want automated arb execution, PolyArb packages low-latency connectivity, monitoring, and alerts with a clear productized offering. Evaluate it alongside manual workflows and alternative platforms like Kalshi or PredictIt by comparing fees, settlement mechanics, and legal access.

FAQ
- Is Polymarket betting decentralized?
- Polymarket uses decentralized smart contracts (Gnosis CTF) and runs on Polygon, but it routes user transactions through a Relayer to sponsor gas. Resolution uses the UMA optimistic oracle.
- Can I arbitrage on Polymarket safely?
- Intra-market arbitrage (buying a complete set when sums are below $1.00) is a well-known strategy, but it carries risks: resolution disputes, partial fills and slippage, fees, and smart-contract risk. PolyArb automates execution to reduce latency and slippage but does not eliminate those risks.
- How does PolyArb differ from free bots?
- PolyArb focuses on low latency (around 40ms vs ~800ms for many free bots), non-custodial execution, Telegram and Discord alerts, and a product guarantee of a $7.62 minimum edge per trade as part of its $99/month plan.
