Vitalik: The Success of Prediction Markets Depends on Oracles
Ethereum co-founder Vitalik Buterin stated, "The quality of prediction markets entirely depends on their oracles."
He expressed happiness to see prediction markets shifting towards decentralized and non-financial oracle solutions, avoiding centralized risks and financial speculation distortions.
Vitalik further pointed out that the next step should be to achieve privacy in attester voting to enhance mechanism security and resistance to censorship.

Vitalik has continuously focused on the infrastructure of prediction markets since raising the oracle issue in Ethereum in 2018, previously criticizing centralized or financialized oracle solutions like Polymarket. This statement continues his long-standing position advocating for decentralized oracles (such as those based on Ethereum consensus or zero-knowledge proofs).
In terms of capital pathways, prediction markets are shifting liquidity from mere financial speculation to real information aggregation, reducing manipulation risks through non-financial oracles. At the same time, privacy in attester voting can lower bribery and attack vectors, attracting more institutions and real event participants to inject capital.
The lessons from the early failures of Augur's oracles and the current hybrid models of Polymarket and Kalshi indicate that the prediction market industry is at a critical stage of transitioning from early financial gambling to mature information infrastructure.
Essentially, this is a technological replacement: Vitalik is promoting prediction markets to use decentralized and privacy-focused oracles, replacing traditional centralized data sources and financially driven models, shifting capital from speculative bets to real-world event pricing mechanisms. Mechanically, this reduces collusion risks through privacy voting, facilitating the upgrade of prediction markets from entertainment tools to infrastructure for social truth.

No matter how lively prediction markets are, if the oracles are untrustworthy, they are just high-end casinos. Decentralization alone is not enough; financialization must also be reduced to allow truth, not capital, to determine outcomes. Privacy voting is not a detail but the last line of defense against the mechanism being bought out.
