Vitalik Buterin Questions Current Incentives in Prediction Markets

Ethereum co-founder argues long-term growth depends on aligning prediction markets with real financial needs.

Prediction markets have expanded rapidly, attracting liquidity and growing public attention. However, Ethereum co-founder Vitalik Buterin believes current growth may be drifting in the wrong direction. In a recent post, he questioned incentive structures that favor short-term speculation over meaningful economic use. 

Ethereum Co-Founder Flags Structural Risks in Prediction Market Growth

Vitalik Buterin recently expressed concerns about the incentive structures shaping modern prediction markets. He argues that short-term crypto price bets and sports gambling are dominating activities. Such markets attract attention and trading fees. However, they offer limited long-term social value.

According to Buterin, platforms appear to be focusing more on short-term bets that appear exciting. These bets bring traffic and fees, especially during bear markets when revenue is harder to find. He warns that relying too much on traders who make poor or emotional bets can hurt a platform’s reputation over time.

Prediction markets rely on two core participants. First, informed traders contribute insights and seek profit. Second, another group must accept expected losses. Sustainable design depends on understanding who willingly takes that losing side.

Ethereum’s co-founder also explains that prediction markets rely on two core participants. First, traders who provide useful information and seek to profit. Second, another group that takes the opposite side of those trades and, on average, loses money. For a market to last, it needs a good reason why that second group keeps participating.

Moreover, Buterin argued that only three types of participants are likely to accept consistent losses in prediction markets. First, naive traders enter positions based on weak or incorrect assumptions, and as a result, lose capital over time due to flawed judgment.

Second, information buyers deliberately fund liquidity, often through automated market makers. By seeding liquidity, they hope to reveal valuable knowledge from traders. Once information becomes public, non-paying actors benefit as well.

Third, hedgers accept a negative expected value in exchange for risk management. This group uses prediction markets as a form of financial insurance to offset exposure elsewhere in their portfolios or business operations.

Buterin takes the idea beyond investing and applies it to currency design. Stablecoin users ultimately seek price stability for future expenses. These users want to be sure they can pay future bills and expenses. Dollar-backed tokens help with that in the short term because they track the US dollar.

However, relying on the dollar means crypto still depends on traditional financial systems, limiting true decentralization. He also points out that people do not all spend money in the same way. Everyone has different needs, costs, and lifestyles. Thus, a single “stable” currency may not align with everyone’s actual expenses.

Buterin Proposes Expense-Linked Market Baskets for Financial Stability

Buterin proposed a system built around category-based price indices. Major expense groups, such as housing, transportation, or utilities, would each have corresponding prediction markets. These markets would price future changes in specific cost segments.

Under this model, users would hold personalized baskets of prediction market shares. Each basket would reflect a set number of days of expected future expenses. Rather than relying on a fiat-pegged token, stability would derive from directly matching assets to individual spending exposure.

Now, 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.

Vitalik Buterin said.

Buterin argues that, if implemented successfully, such a model could offer a more durable foundation. Under this structure, both sides would gain clear economic value. Informed traders would earn by pricing risk accurately, while hedgers would secure downside protection and income stability.
