Futarchy is a governance system in which decisions are settled by prediction markets rather than by counting votes. Proposed in 2000 by the economist Robin Hanson, its one-line design is "vote on values, but bet on beliefs": a community decides what it wants to maximise — a measurable success metric — and speculative markets decide which proposal is most likely to achieve it. For each decision, traders bet on the value of that metric in two conditional worlds, one where the proposal passes and one where it fails; whichever world the market prices higher becomes policy. It is the most market-native alternative to the ballot-based mechanisms most DAOs use, and after two decades as a mostly theoretical curiosity it now runs live on-chain.

Vote on values, bet on beliefs

Hanson's insight was to separate two questions a normal vote fuses together. A token-weighted vote asks holders to simultaneously express what they want and predict whether a given action will deliver it — and it rewards neither honesty nor accuracy, because a single vote almost never changes the outcome. Futarchy splits the two. The electorate (in a DAO, its token holders) democratically fixes a welfare metric — Hanson's original example was GDP-per-capita; on-chain it is almost always the DAO's own token price, a rough but liquid proxy for organisational value. Then, for every proposal, a decision market forecasts that metric conditional on the proposal passing versus failing. Because participants stand to win or lose real money on their forecasts, the mechanism is designed to pull information out of whoever holds it — an expert with a strong view can move the price by trading on it, rather than being outvoted by a larger but less-informed crowd. Values stay democratic; beliefs get priced.

Decision markets on-chain

Turning Hanson's proposal into working software is mostly a market-design problem: the markets must be liquid enough to price accurately and hard enough to manipulate that the verdict can be trusted. MetaDAO, the reference implementation on Solana, does it with conditional tokens. When a proposal goes live, the DAO takes roughly half the liquidity from its spot pool and moves it into two conditional markets — a pass market and a fail market — so neither starts empty. Spot tokens are split into conditional versions, and a conditional trade reverts if its world does not happen: buy in the pass market and the proposal fails, and your trade simply unwinds as though it never occurred. That structure lets traders take real positions on the outcome without betting on the wrong branch. After a fixed window — three days in MetaDAO's current configuration — the protocol compares a manipulation-resistant lagging TWAP (time-weighted average price, which caps how far the recorded price can jump per update) between the two markets. If the pass market's TWAP beats the fail market's by more than a set threshold, the proposal executes automatically; otherwise it dies. The threshold and window are governance-tunable parameters, not fixed law.

Where it is being tried

Futarchy spent most of its life as a thought experiment — Hanson floated it, Vitalik Buterin sketched a crypto version in 2014, and a handful of projects toyed with it — but until recently no organisation ran on it. MetaDAO changed that: launched in November 2023 with a tiny treasury, it governs itself by futarchy and has since run binding proposals for more than a dozen other organisations, making it the first DAO where market prices, not token votes, are the final word on every material decision. In 2026 the model reached a blue-chip DAO in advisory form: GnosisDAO's GIP-145, a nine-month "advisory futarchy" pilot with Futarchy Labs, put a widget on Snapshot proposals showing the estimated percentage impact of a proposal on the GNO price, backed by $100,000 in temporary GNO/WETH liquidity to bootstrap the markets. It runs alongside the existing Snapshot vote — a price signal voters may consult but are not bound to follow — a telling middle path for a DAO not yet ready to hand policy entirely to a market.

Strengths, and where it breaks

Futarchy's appeal is that it attacks two chronic DAO failures at once: voter apathy (you no longer need a quorum of informed voters, only a few informed traders) and the fact that ordinary voting rewards neither conviction nor being right. Its failure modes are equally sharp. Thin markets price badly and are cheap to push, which is why liquidity-bootstrapping is the central engineering problem and why the model works best where the token is already liquid. Metric gaming is the deeper hazard: whatever proxy you choose, you get Goodhart's law — optimise hard for token price and you can reward decisions that pump the price while hollowing out the thing the price was meant to measure. Choosing whose welfare the metric captures is itself an unresolved political question, not a market one. And a rich actor can, in principle, subsidise a market to steer a decision, betting that the value of controlling the outcome exceeds the trading loss — a live concern the governance-attack literature takes seriously. Futarchy does not remove politics from a DAO; it relocates it to the choice of metric and the design of the market.

How Caper approaches this

Caper and futarchy start from the same complaint — that one-block, capital-only voting aggregates the wrong signal — but answer it in opposite registers. Futarchy externalises the judgement to a market and lets price stand in for collective belief; a caper keeps the judgement with its members and instead changes what a vote weighs. Voting power on a Caper proposal is the canonical formula w = (t · v) / (V · T), where t is your governance-token balance and v is your accumulated participation — a soulbound record earned by showing up to vote, which cannot be bought in a block the way a market position can. That makes a large but disengaged holder structurally weaker than a long-standing contributor, without asking anyone to price the DAO's future in a conditional AMM. It also sidesteps futarchy's metric problem: there is no single proxy to game, because each proposal resolves to a definite executed outcome rather than to a market's verdict on a number. And because that same weight sets a member's pro-rata exit share, the incentive to accumulate participation honestly is built in — a different bet than futarchy's, that who decides is easier to get right than what to measure.
