Vitalik Buterin Shares New Proposition for Prediction Markets

Vitalik Buterin has outlined a vision for prediction markets that moves beyond short-term speculation and toward personalized financial stability tools.

In a recent post, he argued that today’s markets are converging too heavily around crypto price bets and sports wagering, and instead should evolve into instruments that help users hedge real-world economic risk.

The proposal centers on using local large language models (LLMs) to construct customized baskets of prediction market shares that reflect each user’s expected future expenses. Rather than holding stablecoins for generic price stability, individuals could hedge their personal cost-of-living exposure directly.

From Speculation to Hedging Infrastructure

Buterin acknowledged that prediction markets have achieved meaningful scale, with enough liquidity to support full-time traders. However, he warned that the current product-market fit leans too heavily toward dopamine-driven, short-term betting rather than long-term informational value.

He described three types of participants in prediction markets:

• Naive traders – individuals with inaccurate opinions who lose money.
• Information buyers – entities that subsidize markets to extract insights.
• Hedgers – users who accept a small negative expected value in exchange for risk reduction.

Buterin argued that relying too much on the first category creates perverse incentives for platforms to cultivate low-quality speculation. The second model, while idealistic, faces a public goods problem, since information benefits everyone regardless of who pays.

The third category, hedgers, is where he sees long-term sustainability.

Personalized Risk Reduction Through Prediction Shares

Buterin illustrated the concept using a political election example. If a biotech investor believes one political outcome is better for their holdings, purchasing shares that pay out under the opposite scenario can reduce portfolio volatility. In effect, prediction markets become insurance tools rather than betting platforms.

He then extended the idea to everyday expenses. Instead of relying on dollar-pegged stablecoins for purchasing power protection, users could hold prediction market shares tied to price indices for goods and services they actually consume.

Under this model:

• Price indices would exist for major goods and services across regions.
• Prediction markets would form around those indices.
• A local LLM would analyze a user’s spending profile.
• The system would generate a personalized basket representing “N days of expected future expenses.”

In this framework, users could hold assets such as Ethereum or equities for long-term growth, while using tailored prediction market exposure to hedge inflation or regional cost increases.

Rethinking Stablecoins and Fiat

Buterin questioned whether the concept of fiat currency itself is necessary in a digitally native financial system. Instead of designing a single “ideal stablecoin” tied to a generalized index, he suggested moving toward individualized hedging instruments.

He noted that non-interest-bearing fiat carries high opportunity costs relative to yield-generating assets, which can overwhelm the hedging benefit. For prediction-based hedging to function efficiently, markets would need to be denominated in assets participants actually want to hold, such as interest-bearing fiat equivalents, tokenized equities, or ETH.

A Structural Shift in Financial Design

The broader implication is not about replacing trading platforms, but about redefining what prediction markets optimize for. In Buterin’s view, the next stage of financial evolution should prioritize tools that reduce real economic risk rather than amplify speculative cycles.

If implemented at scale, such a system could transform prediction markets from entertainment-driven liquidity pools into decentralized, personalized economic stabilizers.

His closing message was direct: build the next generation of finance, not speculative excess.
