Vitalik Buterin raises concerns about prediction markets’ “unhealthy” direction

Ethereum co-founder Vitalik Buterin warned that prediction markets are sliding toward “unhealthy product market fit” by focusing on short-term cryptocurrency price bets and sports betting.

Writing on X, Buterin called the trend “corposlop” and argued platforms feel pressured to embrace dopamine-driven content that lacks long-term societal value.

Buterin proposed redirecting prediction markets toward hedging use cases, including a system where personalized prediction market baskets replace fiat currency entirely.

“We do not need fiat currency at all! People can hold stocks, ETH, or whatever else to grow wealth, and personalized prediction market shares when they want stability,” he wrote.

Current model relies on traders with “dumb opinions”

Buterin identified three types of actors willing to lose money in prediction markets: naive traders with incorrect opinions, info buyers running automated market makers to learn information, and hedgers using markets as insurance to reduce risk.

The industry currently depends on naive traders and creates what Buterin called a “fundamentally cursed” dynamic.

“It gives the platform the incentive to seek out traders with dumb opinions, and create a public brand and community that encourages dumb opinions to get more people to come in. This is the slide to corposlop,” he wrote.

Personalized prediction baskets could replace stablecoins

Buterin questioned whether an “ideal stablecoin” based on decentralized global price indices is the right solution. “What if the real solution is to go a step further, and get rid of the concept of currency altogether?” he asked.

The proposed system creates price indices for all major categories of goods and services, treating physical items in different regions as separate categories.

Each user maintains a local large language model understanding their expenses, offering personalized baskets of prediction market shares representing future spending needs.

Users could hold stocks, ETH, or other assets for wealth growth while holding personalized prediction market shares for stability. The system removes fiat currency dependence while allowing customization for individual expense patterns.

Implementation needs prediction markets denominated in assets people want to hold: interest-bearing fiat, wrapped stocks, or ETH. Non-interest-bearing fiat carries opportunity costs that overwhelm hedging value.

“Both sides of the equation are likely to be long-term happy with the product that they are buying, and very large volumes of sophisticated capital will be willing to participate,” Buterin concluded.
