Buterin’s Approach on Prediction Markets

Vitalik Buterin recently revealed his successful strategy on Polymarket, a platform for prediction markets, where he earned $70,000 by implementing what he calls “anti-insanity mode.” This approach involved betting against irrational market behaviors during periods of heightened frenzy.

Buterin shared his insights during a detailed interview with Foresight News in Chiang Mai, where he conveyed his worries that cryptocurrency applications are drifting from their initial purposes, even in light of substantial technological advancements.

His betting strategy centered on identifying markets in “crazy mode” and placing wagers on the unlikelihood of certain events, such as betting against Donald Trump winning the Nobel Peace Prize and predicting that the dollar would not collapse to zero during panic-driven moments.

This announcement coincides with a notable surge in the adoption of prediction markets, with Polymarket's app installations increasing by 1,200% between January and December 2025. Additionally, weekly trading volumes across various platforms skyrocketed from $500 million to nearly $6 billion.

Ethereum's Three Major Concerns

Buterin expressed his current motivations concerning three critical issues that extend beyond mere technical enhancements, raising existential threats for the cryptocurrency sector.

“My biggest fear right now is that the entire industry will eventually degenerate into a place for 100% cryptocurrency speculation, with only conjecture and no real applications,” he stated.

Amid this “doomsday scenario,” Buterin highlighted the urgency to upgrade Ethereum's technology, specifically by enhancing the efficiency and decentralization of Layer 2 networks, while also striving to match Web2 user experiences.

He pointed to an even grimmer possibility: “If we fail with Crypto, the future technological landscape could be dominated by Centralized AI, which poses a significant danger,” he warned.

Buterin emphasized cryptocurrency’s role as “our defense against the trend of digital totalitarianism, helping to preserve diversity and freedom in technology.“

When Technology Progresses, Applications Stagnate

The Ethereum founder identified a growing disconnect in blockchain development over the past year that could jeopardize the industry’s larger goals.

“In the past year, Ethereum has made remarkable strides in scaling technology,” he explained, highlighting the increase in gas capacity from 30 million to 60 million, with aspirations to reach 300 million this year.

However, a report from MigaLabs indicated that Ethereum has faced difficulties with data-heavy blocks following December’s Fusaka upgrade, with missed-slot rates surpassing 1.7% when blob counts exceed 16.

Despite these technological advancements, Buterin voiced concerns about stagnation at the application layer, noting that prediction markets are the only sector currently showing significant growth in 2025, while also exposing major issues.

He criticized Polymarket’s emphasis on short-term bets, like hourly Bitcoin price fluctuations and weekly sports results. “These short-term bets lack lasting social significance,” he remarked, advocating for mechanisms designed for long-term incentives, such as Robin Hanson’s Futarchy concept, which is being tested by MetaDAO to determine governance methods via prediction markets rather than mere wagers.

When discussing priority applications, Buterin advocated for decentralized social networking first, followed by “smarter” DAOs that extend beyond basic token voting. “It can’t just be about issuing a token and having a vote,” he said. “Developers need to consider: What are the specific objectives of this organization? What governance structure is best suited for these objectives?“

In light of ongoing infrastructural challenges, the Ethereum Foundation recently prioritized quantum resistance with a $2 million funding allocation and the formation of a dedicated Post Quantum team.

Oracle Vulnerabilities Impact Prediction Market Growth

Buterin emphasized significant security concerns in existing oracle systems that could undermine the reliability of prediction markets as they expand.

He recounted an example involving a market related to the Ukraine conflict, where maps from the Institute for War Studies were used to ascertain Russian control over a train station. “ISW employees, whether by accident or intention, tampered with their own system, and the maps abruptly indicated that Russian troops controlled the station,” Buterin detailed.

This incident turned a 5% probability event into a certainty before ISW retracted the update the following day.

Current oracle solutions are plagued with limitations. Centralized models such as Bloomberg require trust in a single entity, while decentralized systems like UMA present game-theoretic flaws that can allow major stakeholders to manipulate voting outcomes. “Even if you vote for the truth, if you oppose the majority, the system will label you as the loser, resulting in a monetary loss,” Buterin explained, compelling participants to align votes with major stakeholders instead of the truth.

Nevertheless, despite these warnings, the prediction market economy is thriving. Polymarket has returned to the U.S. market following CFTC approval with minimal taker fees of just 10 basis points, and the company recently secured a $2 billion investment from the Intercontinental Exchange at a valuation nearing $9 billion.
