Idea

'Vote on values, bet on beliefs': elected bodies define a measure of welfare, and prediction markets decide which policies are expected to improve it.

Theory

Robin Hanson proposed futarchy around 2000. It relies on evidence that prediction markets often aggregate information well.

Real examples

  • Some blockchain projects use conditional markets to select proposals.
  • Corporate prediction markets have been used to forecast internal outcomes.

Critique

Markets can be manipulated, thin markets are noisy, and agreeing on a single welfare measure is itself highly political. Long-term effects are hard to price.

Results

No government uses futarchy. It remains a proposal with small on-chain trials.

TheoryCLM-0038 · checked 2026-10-23

Futarchy has not been tested as the governance system of any country or city; experiments have been limited to small online organisations.[1]
