Approximately 12 hours before the announcement of the Nobel Peace Prize, a newly registered account named "6741" on Polymarket began to heavily bet on Machado's victory. Under the influence of "6741", Machado’s odds surged from around 5% to 70% within minutes, ultimately securing profits exceeding $50,000. In this relatively low-volume market, these bets were sufficient to significantly alter the odds.
A mysterious trader's precise wager 12 hours before the announcement of the Nobel Peace Prize has sparked a storm of speculation regarding insider trading.
According to media reports on Saturday, a newly registered user with the alias "6741" made a substantial purchase on Polymarket, a cryptocurrency prediction market, just 12 hours before Venezuelan opposition leader María Corina Machado was awarded the 2024 Nobel Peace Prize. This action pushed Machado’s probability of winning from 5% to 70%, ultimately yielding profits exceeding $50,000.
The Norwegian Nobel Institute has launched an investigation, suspecting a potential information leak. Erik Aasheim, a spokesperson for the institute, stated: "We have noticed that someone made a substantial profit by betting on this year's prize, and we will investigate whether this implies illegal access to our internal information."
This incident highlights the regulatory blind spots faced by the rapidly growing prediction markets. As an offshore platform without regulation, Polymarket does not prohibit insider trading nor is it subject to relevant U.S. laws.
The event occurred at a pivotal moment when Polymarket's valuation surged to $8 billion. Earlier this week, the parent company of the New York Stock Exchange announced plans to invest up to $20 billion in the platform, underscoring the growing interest of mainstream financial institutions in prediction markets.
Midnight Surge: The Mysterious Account’s Precise Strike
The dramatic scene unfolded at midnight Oslo time on Friday, approximately 12 hours before the announcement of the Nobel Peace Prize. A newly registered account named "6741" suddenly began aggressively betting on Machado's win.
At the time, Machado was neither considered a leading candidate in expert forecasts nor media reports, with her chances of winning on Polymarket standing at only 3.7%. However, driven by "6741," her odds soared to 31.5% within minutes and subsequently climbed further to 73.5%.

According to Polymarket data, the mysterious trader placed a $1,500 bet backing Machado shortly after midnight, while also wagering $1,085 against the previously favored candidate—the Sudanese 'Emergency Response Room.' In this relatively low-volume market, these bets were sufficient to significantly alter the odds.
Other traders quickly followed this trend, with an account named "GayPride" placing consecutive bets while Machado’s probability of winning fluctuated between 60% and 71%, eventually earning over $85,000 in profits.
The Nobel Committee then made the final decision and called Machado a few minutes before the announcement at 11:00 AM on Friday. The five-member selection committee, comprising a human rights advocate, a foreign policy expert, and three former ministers, all hail from Norway.
Gray Areas Amid Regulatory Vacuum
Polymarket, a cryptocurrency-based prediction market, allows users to place yes-or-no bets on various events spanning politics, sports, and pop culture. The contract prices reflect traders’ assessments of the likelihood of future events.
The platform does not prohibit insider trading. As an offshore, unregulated market that officially bars American participation, it is not subject to U.S. stock market laws prohibiting insider trading. Even if market participants traded based on leaked information about the Nobel Prize decision, it remains unclear whether such trades would be deemed illegal.
Jason Furman, a Harvard economics professor and former advisor to President Obama, posted on the social media platform Bluesky: "A student asked me the other day how prevalent insider trading is in prediction markets. I now have an answer." His post included a screenshot of Polymarket’s Nobel Prize betting market.
Some economists argue that insider trading benefits prediction markets by enhancing predictive accuracy. However, regulated U.S. platforms like Kalshi have implemented policies prohibiting insider trading.
On Polymarket, some users monitor trading data for clues of insider bets and use such activity as a reference for their own investment strategies. In August this year, a user named "romanticpaul" purchased contracts related to Taylor Swift’s engagement shortly before the official announcement, sparking similar concerns.
The Business Ambitions of Prediction Platforms
This controversy arises at a pivotal moment for Polymarket’s commercial expansion. This week, Intercontinental Exchange, the parent company of the New York Stock Exchange, announced an $8 billion valuation of the platform and plans to invest up to $2 billion, underscoring growing mainstream financial interest in prediction markets.
Polymarket, founded in 2020, currently prohibits users from the United States as a result of a settlement agreement reached with the U.S. Commodity Futures Trading Commission (CFTC) in 2022. In recent months, the company has acquired a small exchange licensed by the CFTC and hinted at plans to re-enter the U.S. market.
Polymarket gained prominence for its accurate prediction of the 2024 U.S. presidential election outcome, with its forecast of a Trump victory proving more precise than traditional polls. The platform has established close ties with the new U.S. administration—Donald Trump Jr. serves as a strategic advisor to its competitor Kalshi and is also an investor in Polymarket.
Sports betting is viewed as a potential growth area for Polymarket in the U.S. market. Kalshi already offers betting contracts on professional sports events such as soccer and basketball, beginning to erode the market share of traditional sports betting platforms like DraftKings and FanDuel, which is owned by Flutter Entertainment.
