Q3 prediction market trading volume was overstated
Start here
AI-assisted source synthesis · not an independent investigation.
In the third quarter of 2026, four prediction markets reported a combined nominal trading volume of $179.6 billion, but traders actually paid only $56.1 billion. Finance Magnates reported on November 10 that the difference was approximately $123 billion, mainly because low-priced multi-leg combination trades (combos) were included in the nominal trading volume. This means there is a significant discrepancy between the Q3 trading volume disclosed by the relevant platforms and the amounts actually paid by traders. The report did not specify the names of the four platforms or provide any subsequent regulatory or platform responses.
