Prop 50 Polymarket: what traders need to know
Prop 50 on Polymarket is a specific market search term traders use to find the on-chain event labeled "prop 50"; if you landed here because you want to trade or arbitrage that market, this guide explains where it fits in Polymarket’s market structure and how PolyArb (our arbitrage bot) approaches it. PolyArb is non-custodial, live today, $99/month, and advertises 40ms latency with Telegram and Discord alerts. Below are practical notes about liquidity, pricing symmetry, and the real risks you must track before attempting an intra-market arb.
How Prop 50 appears on Polymarket
On Polymarket every market (including anything labelled prop 50) is an on-chain CLOB-driven prediction market on Polygon using pUSD. Outcomes are ERC-1155 tokens under the Gnosis CTF. Binary markets enforce complementary prices — YES + NO should sum to $1.00 at fair value — and multi-outcome markets sum to $1.00 across all outcomes. Use the Gamma API’s /markets endpoint to find the exact market id or slug if you want programmatic access.
Where arbitrage shows up
Intra-market arbitrage exists when the sum of best-ask prices across complementary outcomes is below $1.00. For a binary like Prop 50 that means bestAsk(YES) + bestAsk(NO) < $1.00. PolyArb continuously scans order books, spots those inefficiencies, and routes FAK orders through the CLOB to capture the spread. Remember that ticks, partial fills, and maker/taker fee variation can affect realized profit.
Risks and settlement caveats
No spread is truly free. Resolution risk (UMA disputes), settlement timing, slippage, partial fills, tick-size changes near price extremes, and smart-contract risk all matter. Polymarket sponsors gas via the Relayer and maker fees are zero, but taker fees can vary by category. PolyArb lists the edge it targets alongside these operational risks so you can make an informed decision.
