Arbitrage in Crypto: How It Works and Where PolyArb Fits

Arbitrage in crypto is the practice of profiting from price differences across markets or outcomes. On Polymarket, the most reliable form is intra-market arbitrage: buying a complete set of outcomes when their best-ask sum is below $1.00. PolyArb automates that process, offering $99/month, 40ms latency vs ~800ms for free bots, Telegram and Discord alerts, non-custodial execution, and a $7.62 minimum guaranteed edge per trade. Arbitrage can be systematic, but it carries platform, resolution, and execution risks you should understand.

How crypto arbitrage works in practice

Arbitrage exploits price discrepancies. On binary or multi-outcome prediction markets the fair sum of outcomes is $1.00; when the sum of best asks is lower, buying the full set locks a mathematical edge equal to $1.00 minus that sum. Execution requires fast mid-market reads, immediate order placement, and the ability to mint or merge outcome tokens if you need to form a complete set for settlement. Successful bots track the order book, calculate edge after fees and tick size, and execute FAK or limit orders to capture spreads before others.

Why latency and execution matter

Spreads on liquid markets often last seconds; latency and refresh cadence decide whether a bot wins the race. PolyArb advertises 40ms latency compared with ~800ms for many free options, which materially increases capture probability on short-lived edges. Faster execution also reduces partial fills and slippage, though maker/taker fees and tick-size behavior still affect realized profit. Always factor in taker fees (variable by category), possible tick-size tightening near price extremes, and the time it takes to complete CTF operations on Polymarket.

Risks you must acknowledge

No arbitrage is unconditional 'risk-free.' On Polymarket, resolution disputes via UMA, settlement timing, smart-contract risk, API or relayer outages, partial fills, and fee changes can erode or reverse expected profit. Geo restrictions and Terms of Service rules also affect who can trade and how. PolyArb is non-custodial, but operational and oracle risks remain. Good risk management means sizing positions, monitoring UMA disputes near resolution, and understanding Polymarket's gasless relayer and CTF token lifecycle.

Where PolyArb fits the workflow

PolyArb automates intra-Polymarket arbitrage: continuous book scanning, edge calculation, and order routing with alerts to Telegram and Discord. The product offers a guaranteed minimum edge per trade ($7.62) and non-custodial execution for $99/month, live today. It's intended for traders who want a latency advantage and turnkey alerting, not as a substitute for monitoring resolution risk or compliance with geographic rules. If you trade across other platforms (Kalshi, PredictIt, Manifold), remember PolyArb focuses on intra-Polymarket opportunities; cross-platform strategies are a different class with separate tooling.

Is arbitrage on Polymarket risk-free?
No. The raw spread may be mathematical, but risks include UMA resolution disputes, settlement timing, slippage, partial fills, changing fees, and operational outages. Always factor these into expected returns.
