Futarchy is governance by betting. It replaces democratic deliberation with a market where traders bet on the outcome of policy proposals, creating a direct financial incentive to be right. This mechanism, pioneered by economist Robin Hanson, is now being tested in DAOs like Axie Infinity's Ronin chain.
Why Futarchy Is a Dangerous Experiment for Urban Management
Governance-by-prediction-markets, as proposed by Robin Hanson, outsources policy to speculative forces, creating perverse real-world incentives for network states and pop-up cities. This is a first-principles critique for builders.
Introduction
Futarchy proposes replacing political debate with prediction markets, a dangerous abstraction for managing complex urban systems.
Urban management is not a casino. Cities are complex, adaptive systems where policy outcomes are lagging, multi-variate, and non-binary. A market optimized for a single, tradable metric like 'citizen happiness index' will inevitably optimize for the metric, not the outcome, leading to perverse incentives and systemic fragility.
The data is already flawed. Prediction markets like Polymarket and Augur struggle with low liquidity and manipulation on niche questions, making them unreliable for high-stakes urban planning. The Oracle Problem—ensuring accurate, real-world data feeds—becomes a single point of catastrophic failure for a city.
The Core Argument
Futarchy replaces democratic deliberation with market speculation, creating perverse incentives that are catastrophic for public goods.
Markets optimize for profit, not welfare. Futarchy's core mechanism uses prediction markets to decide policy, betting on a chosen metric like GDP. This creates a principal-agent problem where traders profit from market moves, not from the policy's real-world outcome. The system incentivizes policies that are easy to game, not those that create sustainable value.
Liquidity dictates governance. In a futarchy, policy outcomes are determined by where capital flows, mirroring flaws in DeFi governance like Curve's vote-escrow model. This creates plutocracy, where wealthy speculators, not affected citizens, control urban development. The result is policy optimized for financialized metrics, not livability or equity.
Prediction markets are manipulable. Real-world examples like Augur and Polymarket show that low-liquidity markets are vulnerable to oracle manipulation and coordinated attacks. An attacker could profit by betting against a city's well-being, then sabotaging the metric. This is a fatal flaw for managing critical infrastructure.
Evidence: The 2012 Futarchy experiment by Robin Hanson proposed using GDP futures. Critics immediately noted this would incentivize policies that boost short-term GDP at the expense of long-term sustainability and equality, validating the core misalignment.
The Futarchy Resurgence: Why Now?
Futarchy—governing via prediction markets—is gaining traction as a tool for urban policy. This is a high-stakes gamble, not a proven solution.
The Problem: Voter Apathy & Short-Termism
Traditional city governance suffers from low engagement and myopic election cycles. Citizens vote on leaders, not on specific policy outcomes, leading to misaligned incentives and stagnation.
- Key Risk: Markets could amplify the tyranny of the majority or well-funded interests.
- Key Benefit: Creates a continuous, high-stakes feedback loop for every decision.
The Solution: Manifold & Polymarket
Platforms like Polymarket and Manifold Markets provide the low-friction infrastructure needed to run policy prediction markets at city scale.
- Key Mechanism: Citizens bet real capital on the measurable success (e.g., crime rate, traffic flow) of a proposed policy.
- Key Risk: Opens governance to financial speculation and potential market manipulation by whales.
The Fatal Flaw: Quantifying the Unquantifiable
Urban health is defined by metrics like GDP growth or carbon emissions. But social cohesion, equity, and cultural vitality are nearly impossible to measure objectively for a smart contract.
- Key Risk: Optimizing for a narrow metric (Goodhart's Law) will distort behavior and destroy intangible value.
- Key Benefit: Forces explicit, rigorous definition of what "success" means for a city.
The Precedent: DAO Governance & Ocean Protocol
DAOs like Ocean Protocol have experimented with futarchy for treasury management. The results are a cautionary tale for complex civic systems.
- Key Lesson: Markets are efficient at price discovery but terrible at valuing long-term, non-financial goods.
- Key Risk: Replaces democratic legitimacy with plutocratic information aggregation.
The Attack Vector: Sybil & Manipulation
A city-scale prediction market is a fat target for Sybil attacks (fake identities) and wash trading to create false consensus. Existing anti-Sybil tech (Proof of Humanity, Worldcoin) is insufficient for high-stakes governance.
- Key Risk: Urban policy becomes a financial derivatives game for sophisticated actors.
- Key Benefit: Could pioneer new cryptographic identity primitives with real-world stakes.
The Irreversible Gamble
Once a policy market resolves and funds are auto-executed via a DAO treasury (e.g., Aragon, Colony), there is no undo button. This is governance as a high-frequency trading terminal.
- Key Risk: Permanent, algorithmic enforcement of a policy mistake discovered too late.
- Key Benefit: Eliminates bureaucratic inertia and creates unprecedented accountability for results.
The Slippery Slope: From Market to Manipulation
Futarchy's reliance on prediction markets creates perverse incentives that corrupt urban governance.
Prediction markets are manipulable. A governance token's price reflects speculative sentiment, not civic welfare. Attackers can short the token to profit from policies that harm the city, creating a direct financial incentive for sabotage, akin to a decentralized version of Enron's market manipulation.
Liquidity dictates outcomes. The policy with the most capital backing its prediction market wins, not the most rational one. This creates a pay-to-win governance model where wealthy speculators like Jump Crypto or a DAO whale override local expertise, turning city planning into a derivative game.
Real-world evidence exists. The 2022 Mango Markets exploit, where a trader manipulated a prediction market's oracle to steal $114 million, demonstrates the fragility of these systems. Applying this to infrastructure budgets or zoning laws invites catastrophic, financially-motivated attacks on public goods.

Steelman: The Case for Futarchy
Futarchy proposes replacing political debate with market-based prediction to make optimal urban policy decisions.
Markets outperform committees at aggregating dispersed information and forecasting outcomes. A prediction market for a policy's impact, like reduced traffic congestion, creates a financial incentive for truth discovery that a city council debate cannot match.
Decouples values from beliefs. Citizens vote on a measurable goal (e.g., 'increase median income'), and the market bets on which proposed policy best achieves it. This separates the 'what' from the 'how', preventing ideological gridlock over implementation details.
Incentivizes expert participation. Specialists with non-public data, like traffic engineers or epidemiologists, are financially rewarded for contributing their knowledge to the forecast. This creates a continuous information revelation mechanism superior to periodic expert testimony.
Evidence: The Good Judgment Project demonstrated that prediction markets consistently outperform intelligence analysts. In a simulated urban context, a market for a new zoning law's effect on housing prices would price in expert analysis, resident sentiment, and developer data simultaneously.
Precedents and Parallels
Futarchy's core mechanism—using prediction markets to guide policy—has failed in practice, offering a clear warning for urban management.
The DAO That Bought Itself: Augur's Governance Paralysis
The decentralized prediction market platform Augur implemented a futarchy-inspired governance system. It failed spectacularly due to market manipulation and voter apathy.\n- Critical Bug Resolution stalled for months as prediction markets failed to attract liquidity.\n- Vote Buying became trivial, allowing whales to skew outcomes for minimal cost.\n- Result: The system was abandoned, reverting to a simpler, non-futarchy token vote.
The Manipulation Problem: Gnosis & Omen's Thin Markets
Prediction markets for governance require deep liquidity to be accurate. In practice, they remain illiquid and easily gamed.\n- Low Participation: Niche policy questions fail to attract sufficient betting volume, rendering prices meaningless noise.\n- Synthetic Attack Vectors: An attacker can profit more by manipulating the market outcome than by the policy's real-world effect.\n- Parallel: This mirrors how a real estate developer could profitably bet against a city zoning policy they secretly intend to sabotage.
The Oracle Dilemma: Real-World Data is Subjective
Futarchy assumes a clean, objective metric for success (e.g., "city happiness index"). In urban policy, success metrics are inherently political and gameable.\n- Metric Corruption: Officials will optimize for the measured metric (e.g., GDP per capita) at the expense of unmeasured civic health.\n- Oracle Centralization: Determining the "true" outcome requires a trusted oracle, reintroducing the central point of failure futarchy aims to eliminate.\n- Precedent: This is the Goodhart's Law problem that plagues all metric-driven governance, from corporate KPIs to MakerDAO's stability fee polls.
The Speed Mismatch: Markets vs. Civic Timelines
Prediction markets settle in days or weeks. Urban infrastructure projects and policy impacts unfold over years or decades.\n- Temporal Arbitrage: Short-term market incentives (quarterly profits) will systematically undervalue long-term public goods.\n- Liquidity Evaporation: No trader will lock capital in a 10-year prediction market for a new subway line.\n- Contrast: This is why DeFi protocols like Aave use instant snapshot votes, not futarchy, for parameter tweaks—the feedback loop must be tight.
TL;DR for Builders
Futarchy proposes governing cities via prediction markets, turning policy into a speculative asset. Here's why that's a catastrophic design pattern.
The Oracle Problem in Concrete
Prediction markets like Polymarket or Augur require perfect information to price policies. Urban outcomes (e.g., 'crime reduction') are lagging, multi-variable, and easily gamed. Correlated oracles like Chainlink can't solve for subjective, long-term social goods.
- Manipulable Metrics: Stakeholders can influence the measured outcome to profit.
- Time Lag Disaster: A 5-year infrastructure project's 'success' is priced today, divorcing finance from reality.
- Adversarial Data Feeds: Creates perverse incentives to corrupt the data sources that settle the market.
Liquidity > Legitimacy
The system's decision-weight shifts from democratic legitimacy to capital concentration. This mirrors DeFi governance flaws seen in Compound or MakerDAO, but with higher stakes. The richest speculators decide public policy, not the most affected.
- Whale Control: A $10M+ market maker can swing policy votes for profit, not civic good.
- Short-Termism: Markets optimize for immediate trading gains, not sustainable, complex urban health.
- Vulnerable to Sybil Attacks: Unlike token-weighted governance, prediction markets are explicitly plutocratic by design.
The Black Swan Planning Fallacy
Cities must be robust to unpredictable events (pandemics, natural disasters). Prediction markets fail in low-probability, high-impact scenarios because they rely on crowd consensus, which is historically blind to Black Swans. This creates systemic fragility.
- Tail Risk Mispricing: Markets will underprice preparation for rare disasters.
- Reflexivity Crisis: A market predicting 'economic growth' can trigger a recession if it crashes, creating a self-fulfilling prophecy.
- No 'Unknown Unknowns': The mechanism cannot account for fundamentally unforeseeable policy side-effects.
Code is Not Law, It's a Constraint
Futarchy attempts to automate governance with smart contracts on chains like Ethereum or Solana. Urban policy requires nuance, exception-handling, and adaptation. Immutable code is a bug, not a feature, for dynamic human systems.
- Rigidity Trap: A poorly coded market rule (e.g., on Avalanche or Arbitrum) cannot be easily amended during a crisis.
- Upgrade Dilemma: Introducing admin keys or DAO votes to fix code reintroduces the politics futarchy aims to eliminate.
- Execution Layer Risk: Adds bridge hacks and sequencer failures as new civic threat vectors.
