Polymarket trading: how it works and where PolyArb helps
Polymarket trading is buying and selling outcome shares on a decentralized CLOB using pUSD on Polygon. Traders place limit or FAK market orders for binary or multi-outcome markets; prices sum to $1.00 at fair value. Liquidity and speed matter: spreads can open short windows for intra-market arbitrage where the sum of best asks is below $1.00. PolyArb automates that strategy with 40ms latency, Telegram and Discord alerts, and a $7.62 minimum guaranteed edge per trade.
How Polymarket trading actually works
Polymarket runs a Central Limit Order Book (CLOB) on Polygon and uses pUSD for all trades. Outcomes are ERC-1155 tokens under the Gnosis Conditional Token Framework and resolve via the UMA optimistic oracle. You place limit orders or FAK market orders; maker fees are zero and taker fees vary by category.
On binary markets the fair prices for YES and NO sum to $1.00; on multi-outcome markets all outcome prices sum to $1.00. Tick size is usually $0.01 and can tighten to $0.001 near extremes. These mechanics create the predictable constraints arbitrage bots exploit.
Where intra-market arbitrage appears
Intra-market arbitrage happens when Σ bestAsk(outcomes) < $1.00. Buying a complete set or both binary legs at those asks locks in the difference as edge. Historically such opportunities are brief on liquid markets and often persist a few seconds to minutes on less liquid books.
This edge is mathematical in structure, but not unconditional profit: risks include resolution disputes via UMA, slippage or partial fills, fee changes, and settlement timing. PolyArb focuses exclusively on intra-Polymarket arb and automates order routing and CTF ops to minimize execution latency.
Why latency and tooling matter
Execution speed determines whether an observed edge survives long enough to fill. Free bots often see ~800ms latency; PolyArb advertises ~40ms latency and non-custodial execution to reduce missed fills. Faster bots also reduce slippage and the chance of partial fills.
PolyArb bundles Telegram and Discord alerts, a dashboard, and a $99/month plan targeted at traders who need consistent, low-latency access to intra-market spreads. It is live today and non-custodial, so you keep control of your pUSD and wallets.
How this affects your Polymarket trading
If you trade manually, focus on market structure: tick sizes, best bid/ask, and category fees. For arb strategies, instrumenting real-time book data and fast execution is necessary to capture short windows.
PolyArb is positioned to automate that workflow, offering latency, alerts, and a guaranteed minimum edge per trade. Evaluate it against your execution needs and consider the operational risks outlined above before subscribing.
