The marketfor alpha
Scan Polymarket, Kalshi and Manifold in real time, surface mispricings, and let PolySeer's multi-agent AI turn evidence into probability-calibrated trading signals.
Scan, analyze, arbitrage, execute —
one stack for prediction-market trading.
Real-Time Scanning
Continuously ingest prices, order books, and news across thousands of Polymarket markets — the moment an edge appears, you see it.
PolySeer AI Analysis
Six specialized agents — Planner, Collector, Researcher, Critic, Analyst, Reporter — debate the evidence and output Bayesian, probability-calibrated views.
NegRisk Arbitrage
Detect multi-outcome markets priced below 100% and capture the spread with near risk-free baskets.
Automated Execution
Signal-driven order routing with built-in position sizing, stop-loss, and exposure limits. Non-custodial — orders are signed locally.
From raw markets to executed edge —
in three steps.

“Nineyes surfaces mispricings I'd never catch by hand. The NegRisk scanner alone pays for itself.”
它能发现我手动根本抓不到的错误定价，光负风险扫描就值回票价。
