Kalshi and Polymarket have recorded an all-time high in trading volumes for November, reaching a combined figure of US$10 billion, according to data from The Block.
The Block reports that the month was defined by growth of retail activity, deeper platform integrations, and a steady stream of news events that kept traders active.
Prediction markets allow people to trade contracts tied to real-world events, with the prices reflecting what the market believes is the likely outcome of each event. Traders increasingly use these markets to track sentiment around elections, economic news, and global risk factors.
Kalshi led the month’s gains, with monthly spot volume jumping from US$4.4 billion in October to US$5.8 billion in November, breaking its own record.
