[Kalshi Weekend Nominal Trading Volume Reaches $3.9 Billion] According to a report by Jinse Finance, on October 14, the U.S. prediction market platform Kalshi experienced a single-day nominal trading volume of $3.9 billion over the weekend, with parlay-style combination bets contributing approximately 70% of the weekend's nominal trading volume. Analysts also pointed out that nominal trading volume measures the notional value of contracts and does not equate to the actual cash invested by buyers, nor does it represent the number of new users on the platform. Therefore, this metric cannot directly reflect Kalshi's actual capital inflow or user growth.
