Unusual Polymarket Bets on Nobel Peace Prize Winner Spur Probe on Leak

Record bets totaling over $1.8 million surged on María Corina Machado as winner hours before the announcement, prompting the Norwegian Nobel Committee to investigate possible insider trading.

  • On Friday, 10 October 2025, María Corina Machado was named the 2025 Nobel Peace Prize laureate in Oslo, while large wagers on Polymarket surged hours before the announcement.
  • A newly registered Polymarket account 6741 placed a single large wager on Machado hours before the announcement, while @dirtycup and Polymarket whales boosted positions with high-value bets.
  • Platform data shows a total volume of $21,461,938, with around USD 1.85 million traded between 2 a.m. and 11 a.m. Oslo time.
  • The Norwegian Nobel Committee denied any leak, and Kristian Berg Harpviken, Director of the Norwegian Nobel Institute, said the Institute will examine the circumstances but cautioned it is too early to conclude.
  • Journalists and anti-fraud experts urged scrutiny when Philippe Auclair called the data consistent with a leak and Nick Raudenski called it a 'clear warning signal'; prediction markets and regulators will likely scrutinise more closely.
