Futuur vs Metaculus

Futuur was established in 2019 by Tomás Mateo as a global prediction market platform designed to blend crowdsourced intelligence with dual trading environments. Headquartered in Montevideo, Uruguay, Futuur operates a hybrid forecasting architecture where users can participate in either risk-free play-money pools (denominated in OOMS) or real-money cryptocurrency pools across a wide range of geopolitical, technological, and economic markets.

To ensure constant liquidity across thousands of niche and global questions, Futuur utilizes automated market maker (AMM) algorithms and limit orderbook engines. Users trading with real money can fund positions using major digital assets including Bitcoin (BTC), Ethereum (ETH), USD Coin (USDC), Litecoin (LTC), and TRON (TRX). The platform's unique dual-currency structure allows researchers and market participants to compare forecasting accuracy between play-money crowd sentiment and real-money financial stakes.

Metaculus was founded in November 2015 by three scientists at UC Santa Cruz: astrophysicist Anthony Aguirre, astronomer Greg Laughlin, and data scientist Max Wainwright. Aguirre had co-founded the Future of Life Institute the previous year — the organization that famously published the open letter signed by Stephen Hawking and Elon Musk calling for a pause on certain AI research. Metaculus was conceived as a companion instrument: if FLI was going to warn about existential risks, it needed a rigorous way to aggregate what the best thinkers actually believed the probabilities were. The founding insight was different from prediction markets in one essential way. On Polymarket or Kalshi, you risk money. On Metaculus, you risk your reputation. Aguirre's argument was that reputation, properly tracked and scored, produces calibration without the distortions that financial incentives introduce — and that some of the most important questions facing humanity are too long-horizon for any market to price.

The platform grew slowly through the late 2010s, primarily in the effective altruism and rationalist communities — people who took probabilistic reasoning seriously as a practice rather than a theory. COVID-19 changed the scale. When the pandemic began in early 2020, Metaculus launched dedicated epidemiological forecasting tracks. The platform's aggregate predictions on case counts, mortality rates, and vaccine timelines were referenced by public health researchers and, eventually, by organizations that had previously treated crowd forecasting as a curiosity. By 2022, Metaculus had received $5.6 million in grants from Open Philanthropy and over $300,000 from Effective Altruism Funds. Total funding exceeded $8.5 million from Coefficient Giving by 2023.
