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.
A personal project, developed and run for the author's own use. Features are still being built and no services are offered to third parties. Disclaimer
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 study the theoretical spread of buying every outcome (before fees, slippage and execution risk).
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.

Always-on by default.
Scanners never sleep. Nineyes watches thousands of markets around the clock and surfaces signals in under a second.

“Trigger averaging-down off the real ask, never the mid.”
On low-priced legs the spread is a large share of the price, so a mid-based trigger fires the moment a position opens. That came out of live paper testing, not out of the design.
