Polymarket contracts news and market signals

Prediction market heavyweights Kalshi and Polymarket experienced a combined 15 percent drop in trading volume during August, marking the first monthly decline for the sector in a full year. This unexpected pullback interrupts a twelve-month streak of consecutive growth for the leading betting platforms. Investors and liquidity providers are closely watching this shift to determine if it represents a temporary summer lull or a broader cooling of speculative retail interest.
