Vitalik Buterin Warns Prediction Markets Face “Corposlop” Crisis

• Vitalik Buterin says prediction markets chase clicks and quick bets, losing their power to deliver useful, long-term insights.

• He argues markets now depend on uninformed bettors, pushing platforms to value engagement and profit over accurate forecasting.

• Buterin sees a future where prediction markets help people hedge everyday costs, acting more like insurance than gambling tools.

Ethereum co‑founder Vitalik Buterin has issued a stark warning about the current state of prediction markets. He says these markets risk losing meaningful value by focusing on short‑term bets like crypto prices and sports.

Buterin argues this trend weakens long‑term social value and steers teams toward what he calls “corposlop.” He proposes a new role for prediction markets in finance that could replace traditional currency hedging with personalized future expense markets.

Buterin emphasizes that while trading volumes have grown enough to support full‑time market participants, this growth comes at a cost. “Market volume is high enough to make meaningful bets,” he notes, “but also they seem to be over‑converging to an unhealthy product market fit.” Instead of socially useful information, these platforms attract bets driven by dopamine and revenue needs.

Current Problems With Prediction Markets

Buterin identifies two fundamental roles in prediction markets: smart traders and money‑losing counterparts. Smart traders inject useful information into pricing. However, one side must lose money. Currently, markets rely on naive bettors who make uninformed bets. Buterin warns this encourages platforms to actively seek out less experienced traders.

Moreover, he says that relying on uninformed actors encourages brands and communities to cultivate unrealistic or “dumb” opinions just to increase participation. This, he explains, fuels a cycle where platforms prioritize engagement over genuine forecasting value. Consequently, the quality of information and societal benefit stagnates.

Hedging as a New Use Case

Buterin suggests shifting markets toward generalized hedging use cases. He explores scenarios where hedgers enter markets not to gamble, but to reduce risk. For example, owning shares in a biotech firm ties political outcomes to financial risk.

Betting on the underdog can stabilize returns by smoothing volatility, he explains. This framing positions markets as insurance tools rather than pure speculation venues.

“Suppose that you have shares in a biotech company,” Buterin writes, illustrating how prediction markets could lower risk. “Taking a logarithmic model of utility, this risk reduction is worth $0.58.”

Beyond Stablecoins to Expense Index Markets

Buterin then links prediction markets to the future of money itself. Stablecoins aim for price stability, but they still depend on fiat systems. He proposes prediction markets built on price indices across major goods and services. Each user could hold a basket of market shares tailored to expected future expenses.

This vision eliminates traditional currency altogether. People might hold assets for growth and market shares for stability. “We do not need fiat currency at all!” he declares.
