Ethereum co-founder Vitalik Buterin believes prediction markets offer a more balanced and honest way to engage with uncertain events than traditional financial markets or social media debates — especially when emotions are running high.
In a recent post on Farcaster, Buterin shared why he finds prediction markets “healthier” to participate in. At the center of his argument is accountability. Unlike social media, where bold opinions often earn attention without consequences, prediction markets attach real money to beliefs. If a prediction turns out to be wrong, the loss is immediate and unavoidable.
According to Buterin, this simple dynamic forces people to think more carefully before making strong claims. On social platforms, users can confidently declare that a war will “definitely” happen or a crisis is “inevitable,” only to move on when reality proves them wrong. Prediction markets, by contrast, require participants to back up their views with capital.
Another major advantage, Buterin says, lies in how prediction markets are structured. Prices are always limited between 0 and 1, representing probabilities rather than open-ended valuations. This design helps limit hype, extreme speculation, and the kind of reflexive behavior often seen in stock markets. In traditional investing, prices can spiral upward simply because traders believe someone else will buy at a higher price — a pattern commonly linked to pump-and-dump schemes.
Prediction market contracts ultimately settle at either 0 or 1, depending on the outcome. That finality, Buterin argues, prevents assets from drifting into irrational territory driven by pure speculation. As a result, these markets tend to stay calmer and more focused on estimating reality rather than fueling excitement.
Buterin also addressed concerns that prediction markets might encourage harmful actions, such as betting on disasters. He acknowledged the theoretical risk of someone profiting from causing harm, but argued that small-scale prediction markets around large events don’t work that way in practice. More importantly, he noted that traditional stock markets face similar risks — only at much larger volumes.
On a personal level, Buterin shared how prediction markets have helped him manage emotional reactions to breaking news. He described moments when alarming headlines made him anxious, only to feel calmer after checking prices on Polymarket, which often reflected lower probabilities than the headlines suggested.
Polymarket, the largest prediction market platform globally, recently returned to the US in early December 2025 after nearly three years away. The platform had exited the country following a 2022 settlement with the Commodity Futures Trading Commission, which included a $1.4 million fine and a halt to US operations. Its return is being rolled out gradually, starting with sports-related contracts through invitation-based access.
Buterin also criticized mainstream media and social platforms for amplifying sensational narratives. Headlines often push readers toward dramatic conclusions, while social media rewards attention-grabbing predictions without follow-up or verification.
In contrast, Buterin says prediction markets naturally punish bad bets and reward accuracy over time. As a result, they tend to become more truth-seeking and better at reflecting real-world uncertainty than either traditional markets or online discourse.
