Vitalik Cashes $70K Betting Against Wild Polymarket Predictions

Ethereum co-founder Vitalik Buterin just pocketed a cool $70,000—not from a token launch or a protocol upgrade, but from betting against the crowd on a prediction market.
The Polymarket Payday
Polymarket, the crypto-powered prediction platform, has become a playground for wagering on everything from election outcomes to celebrity drama. Buterin spotted an opportunity where the crowd's optimism—or perhaps delusion—overshot reality. He took the other side of the trade. The result? A six-figure score that proves sometimes the smartest money bets on sanity.
Prediction Markets Meet Reality Check
This isn't about insider knowledge. It's about recognizing when market sentiment detaches from plausible outcomes. While retail traders chase moonshots and narrative pumps, a disciplined approach to probability can still print profits. It’s a stark reminder that in crypto, the most reliable alpha might just be a healthy dose of skepticism toward the latest hype cycle—almost as reliable as a Wall Street analyst missing the point entirely.
Buterin’s move highlights a core, often overlooked utility of blockchain: creating transparent, global markets for information. While DeFi yields fluctuate and NFT trends fade, the ability to bet on real-world events with crypto remains a potent, if underrated, innovation. It turns crowd wisdom—and crowd folly—into a tradable asset.
The takeaway? In a sector obsessed with speculative assets, sometimes the best trade is against the speculation itself. Just don't expect your traditional financial advisor to understand it; they're still trying to figure out what a 'wallet' is.
Buterin illustrates the crucial value of prediction markets
Buterin stated that he had invested around $440,000 in Polymarket. After placing a bet on the prediction market in 2025, he generated $70,000 in profit, representing a 16% return. Concerning this profit, the industry executive argued that betting against market HYPE often proves profitable for him. Therefore, according to his argument, bettors target markets driven by extreme, irrational sentiment to maximize their earnings.
Responding to the Ethereum co-founder’s statement, Loxley Fernandes, a prominent Web3 entrepreneur and fintech innovator, and Dastan, CEO of Dastan company, expressed his belief that Buterin’s success stemmed from identifying and profiting from obviously flawed assumptions, demonstrating the significant value of prediction markets.
“When emotional extremes and irrational feelings affect markets, rational players not only make money but also help bring prices back to reality,” he said, further adding that, “ this is exactly what prediction markets are meant to do: provide clear signals amid all the noise.”
However, as with other marketplaces, Buterin disclosed that betting platforms such as Polymarket face key challenges, particularly regarding how oracles operate. Notably, oracles are decentralized third-party services that bridge real-world event outcomes to the blockchain, automatically and securely resolving market bets.
To outline some of the challenges faced, the industry executive highlighted an example of a prediction market connected to the Russia-Ukraine conflict. In this prediction market, individuals bet on whether the Russian army WOULD seize control of Myrnohrad, a city in Ukraine. Here, the Oracle for this prediction market used maps retrieved from the Institute for the Study of War (ISW), a nonpartisan, nonprofit Washington, D.C.-based think tank.
Buterin raises concerns about prediction market oracles’ security measures
Regarding the ISW-sourced maps, Buterin mentioned that they were shared on the social media platform X. In the Russia-Ukraine conflict, an industry executive noted that the prediction market determined “control” based on which army controlled the city’s train station.
Upon the breach of the ISW’s X account, the think tank’s maps were swiftly updated to show that Russian forces controlled the train station. The following day, the Institute apologized and removed the incorrect information.
In the meantime, the precise payout figures were not officially disclosed. Still, local media in Ukraine reported that some participants in this bet may have received returns exceeding 33,000%, with trading volume of approximately $1.3 million.
At this moment, reports noted that Buterin shared such examples to demonstrate that the security measures of prediction market oracles are inadequate. “They never thought that one message they shared would decide who owned $1 million on the blockchain,” he said.
