Prediction markets’ October trading volume reached $128 billion, equivalent to approximately 171 trillion wo

Prediction markets posted $128 billion (roughly 171 trillion won) in notional October trading volume, according to a DeFi Rate snapshot taken Nov. 1 at 11:30 p.m. ET, with the tracker's page showing a 63% month-over-month increase. The 63% growth figure compares the eight platforms that reported data in both September and October, while the October monthly total aggregates nine platforms, including Rothera, which was excluded from the month-over-month comparison. DeFi Rate counts each contract at a $1 face value (about 1,333 won) regardless of actual execution price, so the notional figure differs from real payouts. The methodology matters for anyone benchmarking sector growth, since headline volume can overstate actual economic activity. Watch for whether November volumes sustain the pace and whether trackers converge on standardized notional-versus-payout reporting.
