Frequently asked

Where is the liquidity in prediction markets right now?

Across Kalshi and Polymarket, 2,412 active questions carry $56.6M of 24-hour volume. The liquidity heatmap on this page sorts every market by time-to-resolution (x-axis) and 24h volume (y-axis), so the brightest dots and densest cells show exactly which sectors and resolution windows are absorbing the most capital today.

How do I find the most liquid prediction markets to trade?

Use the venue and liquidity-floor filters on this page (Both / Kalshi / Polymarket and $100+ / $1K+ / $10K+ thresholds), or open /screen for a full-table screener with sortable IY, CRI, τ, RV, VR, and IAR filters across the same dataset.

What indicators are overlaid on the heatmap?

Five indicators recolor the topography: IAR (information arrival rate, price changes per hour), VR (vol budget — realized vol / theoretical max for a binary martingale), RV (realized volatility, annualized 48h stddev), IY (implied yield to expiry), and CRI (cliff risk, pace toward resolution). Pick one and the dots get brighter where that signal is hot.

How fresh is this data?

The market_indicators table is recomputed every 15 minutes from the Kalshi Events API and the Polymarket Gamma API. Page-level data is cached at the edge for 15 minutes (revalidate=900).

Are these prediction markets accurate?

On the resolved sample, the t-24h Brier score is in the fair-to-good range. See /calibration for the full calibration curve, by-venue and by-category breakdowns, and methodology.
