Research tools

Do the work, then read the methodology

High-intent research should not end at an article. Start with a calculator, replay, wallet audit, market workspace or data sample; use the linked guides to inspect the assumptions behind the result.

Free calculator

Prediction-market slippage calculator

Paste displayed bids or asks and walk the ladder for a requested order size. See fillable shares, VWAP, worst price, unfilled size and modeled slippage.

Calculate slippage →No account · no live trading

Execution research

Backtest Lab

Test stated entry and exit rules against recorded Polymarket and Kalshi books with midpoint, fixed-slippage and depth-aware VWAP fill models.

Open Backtest Lab →Recorded L2 · reproducible parameters

Public-wallet research

Wallet Intelligence

Inspect public Polymarket positions, activity and PnL context, then audit whether comparable displayed depth remained after eligible trades.

Analyze a wallet →Read only · no private keys

Market workflow

Sports workspace

Explore sports prediction markets while preserving venue identifiers, contract timing and the order-book evidence needed for point-in-time research.

Developer access

API documentation

Inspect the historical REST and live WebSocket contracts, normalized ladder fields, timestamps, identifiers and pagination behavior.

Research standard

Every output should expose its assumptions

A useful prediction-market tool identifies its source observation, timing, market identifiers, side, size, fill rule and missing-data behavior. It should separate displayed liquidity from guaranteed execution and make a result reproducible by another researcher.

Use the free calculator to test one ladder before moving into a historical replay. When the workflow needs repeated requests, exports, multiple venues, or a live feed, inspect the API contract and documented coverage before selecting a plan. Wallet and arena outputs are research views, not endorsements or promises of future performance; preserve the underlying market identifiers when comparing a result elsewhere.
