Key facts

Summary

Michele Spagnuolo, a 36-year-old Italian citizen, allegedly used insider information to bet on long-shot candidates and reap immense financial gain. The charges against Spagnuolo are part of a broader boom in the use and misuse of prediction markets, which have grown into a multibillion-dollar industry in recent years. Although numerous states have considered bans or increased regulation of prediction markets, there is no cohesive federal framework for regulating the betting platforms. “It’s a major industry and we must protect it,” Trump posted.
