The Night Oslo Leaked, and the Night It Didn't

About this episode

In October 2025, hours before the Nobel Peace Prize announcement, María Corina Machado's Polymarket price climbed from about four percent to over seventy while Oslo slept. The Norwegian Nobel Institute opened an inquiry and in January 2026 concluded that the result had most likely been stolen through digital espionage. Its director said it was not possible to determine who was behind it. Four days ago a chart with the same overnight shape lifted Yulia Navalnaya past fifty percent. The prize went to Navi Pillay, a name neither Polymarket nor Kalshi had listed.

Nadia and Miles rebuild both nights from the timestamps, test the explanations against each other (crowd wisdom, an insider, a theft, a few large accounts, plain noise) and set out what evidence would actually settle it. No account named in this episode has been identified or charged with anything. Nothing here is trading advice.

On January 30, 2026, Reuters reported the Nobel Committee's conclusion that the Peace Prize winner was likely revealed early by digital spying, and that officials could not determine how the breach happened or who was responsible, saying criminal or state actors could be involved and that it was unknown whether the motive was profit or damaging the prize's credibility.

   Corrected The evidence does not say officials concluded they were likely prey to a criminal actor seeking profit. It says criminal or state actors could be involved and the motive, profit or harming the prize's credibility, is unknown.

25. In October 2026, Kalshi opened a review of three bets totalling about $173, placed when Katie Zacharia traded at about 1% odds to be named White House press secretary: one $19 bet placed around 10:42 p.m. ET on October 8, about 15 hours before the October 9 announcement, and two bets of about $74 and $80 placed around 1:41 p.m. ET on October 9, less than 20 minutes before reports surfaced.
