Crypto News, Trump has recently softened his stance on prediction markets, saying that many smart people support these platforms and noting that other countries are adopting them. Trump told reporters in Florida that he realizes many influential people support these platforms and warned that the U.S. could fall behind if it does not get involved in this trend. Previously, he had expressed dissatisfaction with the growth of prediction markets and believed that the modern world is too much like a casino. According to Token Terminal data, the combined trading volume of Polymarket and Kalshi in March totaled $23.6 billion. Trump’s shift in attitude may be related to his family’s ties to the industry: his son, Donald Trump Jr., invested in Polymarket in August and served as an adviser to Kalshi in January 2025.
