Catie Di Stefano

Founder, PredictionRanks

Catie Di Stefano has spent 15 years inside the regulated gambling industry — starting at Betsson Group in Malta, then nearly five years at Gaming Innovation Group (GiG) rising to B2C Group VIP Manager. She built an independent consultancy spanning European and US iGaming brands, including a licensed engagement with Hard Rock Hotel & Casino Atlantic City under a New Jersey DGE vendor license, before building the OnlineGamblers.com brand from the ground up and holding marketing director roles at Smartico.ai and Vegas Kings. She was covering prediction markets specifically as early as 2022, speaking on a Next.io New York panel about NFT's and Web3 prediction platforms — years before founding this network. She has been named to multiple iGamingExpress industry rankings, including the Top 70 Most Influential Women in iGaming and the Top 25 Women Shaping the Future of the Gaming Industry, and has shared conference stages with the American Gaming Association, Morgan Stanley, MLB, and the NY Jets on regulation and responsible gaming. PredictionRanks applies that same regulated-market rigor to ranking and reviewing the new wave of CFTC-regulated prediction market platforms.
