Prediction Stackby MIKODESPolymarket lets an interface attach a builder code to the orders its users sign and charge up to 1% on top. Prediction Stack is the interface you brand for your audience — today it reads the chain; the order flow that earns the fee is designed, not built.
The live app runs on committed data from the refresh job. Read-only: no wallet, no orders.

Business plan
Buy the source code once. Run it under your brand. The revenue lines are already in the code — they pay you, not us.

Example scenarios, not a forecast. This release places no orders, so it earns no builder fee yet: the order flow is designed, not built, and Polymarket's builder payout has not been verified. Prediction markets are restricted in many places.
For the operator
What it does
Decodes Polymarket OrderFilled and FeeCharged events from Polygon: fills, prices, fees and which builder code each fill carried.
Read-only · no key, no signatureCounts the fills that carry a builder code and highlights yours, so you can see what an interface like yours moves on-chain.
Income is not estimated — it cannot be read from chainKalshi spreads with every fee counted and annualised over the lock-up. When nothing is positive after fees, it says so.
Spread, not profit — the vocabulary is enforcedScores Kalshi–Polymarket pairs with subject, year, predicate, party and settlement vetoes. Only human-confirmed pairs are ever priced.

Unknown renders “unknown” — no fake dataIllustrations of built features, with numbers from the committed 2026-09-25 snapshot. The live app shows the real screens.
The rest of the product
Both public surfaces are read-only. The console is where the builder code is set and where a person confirms, or rejects, every candidate pair.
Desktop and phone
Real screens from the Prediction Stack demo build, on the devices your users will hold.

This one is a read-only demo: it refuses every change in the server, so nothing you click can break it for the next visitor. On your own install the same screens write for real.
Prediction markets are restricted in many places. The operator decides where it is offered. Not financial or legal advice.
