How MLB markets on Polymarket work

MLB markets on Polymarket are either binary (yes/no) or multi-outcome (e.g., series winner, MVP). Each share pays $1 if its outcome resolves YES and $0 if NO. Trading happens on a Central Limit Order Book (CLOB) denominated in pUSD. Tick size, maker/taker fees, and order types follow Polymarket rules; maker fees are zero and taker fees vary by category.

Where intra-market arbitrage appears in MLB grids

The simplest arb is intra-market: when bestAsk(YES) + bestAsk(NO) < $1.00 you can buy both legs and lock in the difference. For multi-outcome MLB markets the same logic applies across all outcomes. These opportunities are typically brief on liquid games and require low-latency execution to capture before others tighten the book.

Why latency and alerts matter

Arb windows often last seconds; latency determines whether your order fills. PolyArb advertises 40ms latency versus roughly 800ms for free bots — lower latency increases your chance of getting fills at quoted prices. Real-time alerts (Telegram + Discord) let you monitor fills and edge events without maintaining a UI open.

Risks and practical constraints

Never call any trade risk-free unconditionally. Resolution disputes (UMA), partial fills, slippage, fee changes, and settlement timing can reduce or eliminate apparent edge. Polymarket also geo-blocks certain jurisdictions; do not attempt VPN workarounds. PolyArb is non-custodial, but smart-contract and oracle risks remain in the platform.
