Charlotte Nimmo on Why Prediction Markets Disagree on Price

Charlotte Nimmo, founder and CEO of iPredicta, says the growing popularity of prediction markets is now moving beyond politics and into mainstream entertainment and finance. In a 2026 Skynet report cited by the company, global trading volume rose from $15.8 billion in 2024 to $63.5 billion in 2025, with venues able to price the same outcome differently. Nimmo points to competition and contract differences driven by liquidity, user bases, fee structures, and market design. She notes growth signals including FIFA naming ADI Predictstreet as its first official prediction market partner, plus entries from Robinhood, DraftKings and Underdog. She argues regulation must catch up with durable demand.
