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.
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.
ToolsFrom a research question to a result
A calculator, a replay, a wallet audit, a market workspace and the API contract behind them.
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.

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.

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.
