Sports Bet Arbitrage Calculator for Polymarket Traders
A sports bet arbitrage calculator converts market prices into a guaranteed edge by comparing the sum of best-ask prices to $1.00. On Polymarket and similar prediction platforms that list sports outcomes, the calculator shows whether buying every outcome nets a positive spread. Remember the arithmetic edge must be weighed against risks: UMA resolution disputes, slippage, fees, and settlement timing.
How a sports bet arbitrage calculator works
The calculator sums the best-ask prices for all mutually exclusive outcomes; for a binary market it adds YES and NO, for multi-outcome it sums every leg. If the sum is below $1.00 the result is a raw edge equal to $1.00 minus that sum. That arithmetic edge is the starting point for deciding whether to execute an intra-market arbitrage trade on Polymarket. The calculator should also factor in taker fees and expected slippage. Polymarket taker fees vary by category (0%–1.8%), and maker fees are zero. Subtract expected fees and execution slippage from the raw edge before trading.
Practical inputs to include
Enter best-ask prices for every outcome, the exchange’s taker fee rate, and an estimated fill probability or partial-fill loss. For binary markets the tool needs just two prices; for N-way markets it needs N prices. Also include UI conveniences: tick-size rounding (Polymarket uses $0.01 normally and tightens to $0.001 near extremes), currency units in pUSD, and quick conversion to a guaranteed dollar edge so you can compare against fixed costs like builder fees.
When the calculator isn’t enough (risks to watch)
Arithmetic edge doesn’t remove risk. UMA optimistic-oracle disputes can delay or change settlement; smart-contract risk and temporary order-book moves can produce partial fills; geography and account restrictions may prevent order placement. Never treat an output as unconditional profit. Use conservative estimates for slippage and allow a time window for execution—liquid arbitrage opportunities on Polymarket often last seconds to minutes.
