Svmuu reported that Spencer Bogart, a partner at Blockchain Capital, posted on X platform, stating that the total trading volume of Kalshi and Polymarket in March was nearly flat, both at approximately $12 billion ($12.29 billion for the former and $12.22 billion for the latter). Excluding sports-related trading, Polymarket’s non-sports category volume was $7.5 billion, while Kalshi’s was only $1.6 billion. Although there are differences in positioning between the two in the prediction market, it is strange that they are still classified into the same category.
