What is Polymarket arbitrage?
Polymarket arbitrage is the practice of exploiting price inefficiencies in prediction markets. Because Yes and No shares on a binary market should always sum to $1.00, any deviation below $1.00 for the combined outcome is a risk-free profit — minus fees and execution slippage. Cross-market arbitrage extends this to related markets whose implied probabilities should track each other.
How does PolyZig detect arbitrage opportunities?
PolyZig continuously scans Polymarket order books and the public event graph for mispriced outcomes and correlated markets. Our AI pipeline pairs algorithmic filtering with Anthropic Claude deep analysis to validate relationships and score opportunities by profit, liquidity, and confidence. Opportunities are surfaced via WebSocket in under a second.
Is arbitrage on Polymarket risk-free?
No strategy is truly risk-free. Execution risk (partial fills), liquidity risk (thin order books), resolution risk (ambiguous market outcomes), and fee drag can all eat into spread. Most opportunities are 1-5% gross — after costs, 0.5-3% is typical. PolyZig surfaces spreads pre-fees so you can size appropriately.
How fast do arbitrage opportunities disappear?
On active markets, binary mispricings often close in seconds once retail traders react. Deeper cross-market inefficiencies can persist for minutes to hours. PolyZig's mempool monitoring and sub-500ms execution is designed for the former — latency is the single biggest driver of arbitrage profitability on Polymarket.
