What Is Futarchy, and What Is Progno Actually Doing With It?

Futarchy is not just asking who wins a vote. It is asking which choice leads to the better measured future.

Start with the core idea

The usual short version of futarchy is: vote on values, bet on beliefs. A community decides what outcome it cares about, then uses markets to estimate which decision is most likely to produce that outcome.

That matters because ordinary politics often mixes two arguments together. People argue about what goals matter, and they argue about what policy will actually achieve those goals. Futarchy tries to separate those questions.

• First define the target clearly.
• Then compare decisions by their predicted effect on that target.
• Let the forecast, not just rhetoric, carry more weight.

Why markets show up at all

Prediction markets are useful here because they force participants to make explicit, falsifiable claims about the future. Instead of saying a policy is good in a vague way, you put a number on the outcome you expect.

In a strong version of futarchy, the policy with the better predicted outcome would actually be chosen. That is the part most people find radical, and it raises real governance questions.

What Progno copies from futarchy

Progno keeps the conditional forecasting structure. For every Swiss initiative, the platform asks users to forecast a public welfare index under two different worlds: one where the initiative passes and one where it fails.

That means the key object is not vote share. It is the expected index level in each counterfactual future. The spread between those two forecasts is the crowd's claim about whether the initiative helps or hurts the measured outcome.

• Pass world: what does the index look like if the initiative becomes law?
• Fail world: what does the index look like if the status quo remains?
• Difference: which world looks better on the chosen metric?

What Progno does not copy

Progno is not an automated government and it is not a money market. There are no wallets, no payouts, and no mechanism that directly decides Swiss policy. It is a public forecasting interface that helps people reason more concretely about initiative consequences.

That design choice is deliberate. It lowers legal and ethical complexity while preserving the main educational and analytical value: forcing participants to compare two measurable futures instead of two slogans.

Progno is a shadow futarchy product. It borrows the discipline of conditional forecasting without claiming the legal or political authority to replace voting.

Why the index matters so much

A futarchy-style system is only as good as the metric it uses. If the metric is shallow, gameable, or politically incoherent, the forecasts become less meaningful too.

That is why Progno gives each initiative a named public welfare index with explicit components, weights, and source notes. The platform is trying to make the target legible, not hide it behind a black box score.

How to read a Progno market

Suppose an initiative shows a pass forecast of 64 and a fail forecast of 58. The market is not saying the initiative has a 64 percent chance to pass. It is saying the measured welfare outcome looks stronger in the pass world than in the fail world.

If the pass value is below the fail value, the crowd is claiming the opposite. If the values are close together, the market is effectively saying the initiative does not change the measured outcome very much.

Why publish an explainer at all

Most people have never encountered conditional decision markets, and the word futarchy can sound abstract or ideological. Without a plain-language explanation, users can easily misread Progno as either a referendum polling app or a crypto betting site.

It is neither. The product is closer to a structured public reasoning tool: pick a metric, compare both futures, and make your assumptions visible.
