Manipulation, Insider Information, and Regulation in Leveraged Event-Linked Markets
When prediction markets use borrowed money, who cheats and how to stop them
Prediction markets that let traders borrow money to bet create two completely different ways to cheat: manipulating the market price itself, or secretly influencing the real-world event being predicted. Borrowed money makes price manipulation easier but actually changes *whether* it's worth trying to manipulate the event—and across different jurisdictions, regulators have left gaps that savvy traders can exploit.
As prediction markets grow and add leverage features, platforms and regulators need to know which manipulation tactics actually work and which safeguards backfire. Without this roadmap, leverage could shift cheating from hard-to-detect price games to outcome manipulation that distorts real elections, financial forecasts, or sporting events—while traders park their money in whichever country's rules make cheating easiest.
