Methodology
Volume is reported on each venue's own basis: Polymarket and Limitless figures are traded on-chain value (USDC); Kalshi figures are settlement notional (contracts times $1, the basis Kalshi itself reports); Smarkets figures are lifetime matched volume, reported in GBP and converted to USD at our hourly exchange rate; Rothera figures are settlement notional (contracts times $1), read from the exchange's daily public clearing file; Futuur figures are real-money traded volume in USDC only — its parallel play-money book is tracked for market coverage, never as dollars, and Futuur publishes no liquidity figure; Myriad figures are onchain stablecoin traded volume (USDC, USDC.e, USDT, and USD1) only — its play-money Myriad Points markets are tracked for market coverage, never as dollars, and volume on incentive-boosted BNB Chain markets can overstate organic activity; ForecastEx figures are matched-contract notional (each matched Yes/No pair settles to $1), read from the exchange's end-of-day data, so they refresh on a daily (T+1) basis rather than intraday; Gemini figures are provider-reported cumulative and rolling 24-hour matched volume from its public prediction-market API and refresh intraday; Manifold uses play-money and is shown for market coverage only. Metaculus and PredictIt do not publish volume, so their totals appear as zero rather than being estimated. Monetary totals — volume, 24h volume, and liquidity — cover real-money venues only; play-money and forecast platforms such as Manifold and Metaculus contribute market counts and probabilities, not dollar figures. Where the same binary question trades on several real-money venues, event pages also show a CoinRithm reference probability — the liquidity-weighted median across those venues, always displayed with the venue count and the cross-venue spread. Volume and liquidity totals cover currently-open markets: when a market settles, its volume leaves the totals, so day-over-day totals can fall as well as rise.
