The mean absolute cross-venue price gap, in probability points ×100, published directly — no divisor, no chaining, no inception base. A percent change of a dispersion statistic is not a return, so only the absolute move is published.

Equal-weighted. A fragmentation reading asks how far apart venues are on a typical question, so weighting by liquidity would let the deepest handful of markets speak for the whole category.

WETFRAG publishes 40 of the 53 constituents its 2026-09-22 level was computed over — the first 40 the settlement recorded, not a ranked selection, so these are not necessarily the largest. The remainder is real and priced but not written to the settlement row: a full daily roster at this width would be tens of megabytes a year. These holdings are a window on the index, not the index — figures computed from them alone would not reproduce the published level.

A benchmark reading of prediction-market prices. The holdings below are the composition the published close was computed over, priced at the mid, before fees, spread and slippage. W.E.T. is not an exchange and never handles orders — every holding links to the venue that lists it. The index is not directly investable. Data, not advice.
