read-only analytics no orders · no keys

Prediction-market data.
Every fee counted. Read-only.

The Scanner checks Kalshi prices for differences in pricing on historical data, and the Terminal is a read-only view of on-chain Polymarket fills and fees on Polygon. Nothing here places an order, connects a wallet, holds funds or gives advice: it is a research tool, and figures are historical data, not returns. Sports, esports and short-term up/down markets are left out by default (operator setting). The operator admin runs on the operator's own machine, not on this site. Event contracts are regulated differently from country to country and restricted in many; the operator of this site is responsible for the rules where it is published.

Spread Scanner

01
Kalshi ingestion on a scheduled runner, every fee counted on every leg, and a pair matcher that vetoes contracts about different subjects. Research only: no order is placed.

Prediction Terminal

02
A read-only view of Polymarket fills and fees, decoded from the exchange contract's OrderFilled and FeeCharged logs on Polygon. It reads public chain logs only: there is no order form, no wallet connection and no key.

Only events where every outcome is listed, so one leg must pay. Single-venue check on historical data; not a cross-venue result.
No figure on this page is seeded, mocked or placeholder. Counts, amounts and statuses are read from scanner/public/board.json and terminal/public/data/tape.json; operator settings (brand, links, hidden categories) from config/public.json when it exists. Where something is unknown it says unknown. Nothing here promises a return.
