Putting the daily Volume/OI ratio curves of the three major prediction markets on BSC together for comparison makes it easier to see the level of market speculation. Probable's recent Vol/OI ratio reached 2,300%, which is not only high in absolute terms but also shows significant daily fluctuations. When Opinion, Predict Fun, and Probable are plotted on the same graph, the first two are almost overshadowed, with Probable's market turnover—or rather, speculation intensity—significantly surpassing the other two. Opinion and Predict Fun briefly showed higher Volume/OI ratios on certain days during their early stages, but both gradually declined and stabilized. Currently, even though Opinion leads in both trading volume and open interest, its Volume/OI ratio is only about half that of Predict Fun, which can be considered a relatively more mature state.
