Bitcoin ETF Flows on September 22?

Currently, prediction market odds offer a distinct perspective compared to traditional spot price expectations. While spot prices reflect immediate buying and selling pressure, this market aggregates informed speculation about future ETF flows. Discrepancies between the two can indicate areas where the market believes analysts or polls are underestimating or overestimating the likelihood of positive inflows. It's important to note that prediction markets often incorporate information not immediately reflected in spot prices, offering a forward-looking view.
