(FILES) This photo illustration shows set up screens displaying the logo and home page of US based prediction market platform Kalshi, in Saint-Mande, east of Paris, on April 29, 2026. New York's attorney general sued betting platform Kalshi on July 31, 2026, accusing it of running an illegal gambling operation in a case that could shed a spotlight on the lightly regulated and controversial world of prediction markets. The suit alleges that Kalshi, one of the biggest such markets, exposes New Yorkers to "serious personal and financial risk." (Photo by Martin LELIEVRE / AFP via Getty Images)
