According to CoinMeta, data from Dune shows that the total transaction volume in markets such as Polymarket and Kalshi across multiple categories including politics, finance, technology, world events, weather, and culture has exceeded $13 billion. Among these, the transaction volume in the finance category alone reached $2.08 billion. The five largest of these markets track the Federal Reserve's interest rate decisions and are re-priced hourly before each FOMC meeting. In addition, the cross-asset signal markets that attract significant attention from hedge funds and asset management companies include those that track geopolitical risks such as "U.S. military intervention in Iran" and ceasefire situations, the probability of a U.S. government shutdown which reflects fiscal trends in real-time, as well as predictions about the next Federal Reserve chairman, which directly indicate the direction of monetary policy.
