Norwegian authorities are investigating a potential data leak after unusual betting activity on the Polymarket website predicted the 2025 Nobel Peace Prize winner before it was officially announced. The inquiry began when bets favoring Venezuelan opposition leader Maria Corina Machado surged hours before her name was revealed in Oslo on Friday, according to Bloomberg. The investigation follows notice from the Nobel Institute, who confirmed their involvement after observing a significant spike in bets on Machado just before the announcement. The platform’s data indicates that users placed thousands of dollars worth of bets on Machado shortly before the official announcement. Polymarket has also been under scrutiny for past instances where betting activity appeared to mirror insider knowledge regarding information leaks ahead of official pronouncements, and this latest investigation is aimed at determining if someone involved with the Nobel process shared confidential information prior to the prize’s public disclosure.
