Prediction markets have sparked a golden age of insider trading-but the party may be coming to an end | Fortune
"The rise of these prediction markets has given rise to a series of high-profile controversies. One saw a Polymarket user wager $32,000 that President Nicolas Maduro of Venezuela would be out of power—a bet placed only hours before U.S. special forces captured Maduro, earning the bettor a $400,000 payout."
"Insider trading on prediction markets is hardly limited to geopolitics. The problem has also bubbled up in domains like elections, where a California gubernatorial candidate wagered on his own candidacy, and in the tech industry, where a trader made $1.2 million by correctly predicting Google's 'Year in Search' results before they were released."
"Polymarket may be especially prone to these shenanigans, because its corporate structure for now leaves it outside of U.S. and state laws: Its off-shore platform lets users not only place bets, but create wagers of their own with little scrutiny or oversight."
Insider trading has escalated in prediction markets like Kalshi and Polymarket, allowing users to bet on significant events. High-profile cases include a $32,000 wager on Venezuelan President Maduro's ousting, resulting in a $400,000 payout. Similar incidents have occurred in elections and tech, with fears of athletes betting on their performance. The lack of regulatory oversight, particularly for Polymarket, raises concerns about the potential for widespread insider trading, as many insiders may exploit confidential information for profit.
