Today we are announcing that a16z is investing in Kalshi, a regulated exchange for trading on prediction markets. Prediction markets are a modern implementation of a classic economic idea, one most clearly articulated by Friedrich Hayek.
Hayek and the knowledge problem
Hayek argued that no central planner could ever access the dispersed knowledge held by millions of people across an economy, a fundamental challenge that has come to be known as the “knowledge problem.” Much of this knowledge is tacit and unspoken, embedded in people’s experiences, circumstances, and preferences.
Hayek wasn’t just pointing out the limits of central planning. He was offering a solution. In his 1945 essay The Use of Knowledge in Society, Hayek argued that the solution lies in looking outward, not inward: “We need decentralization,” as he put it.
Markets, in Hayek’s view, are not just allocation mechanisms but information systems. Prices act as signals, compressing vast amounts of local knowledge into actionable information. Moreover, prices create incentives: they encourage people to make decisions and act in ways that drive information back into the system. This creates an iterative feedback loop, an engine that drives better performance.
Today we might say that the answer to the knowledge problem is not to give central planners more sophisticated computers. The answer is that markets themselves are the computers. Prediction markets make this idea concrete, applying it to questions about the future and turning collective knowledge into prices that reflect probabilities.
Why we’re investing in Kalshi
This is why we’re excited about prediction markets, and why we’re investing in Kalshi. Kalshi is bringing prediction markets into the mainstream with a compliant, scalable platform for event contracts covering everything from elections and economics to sports and culture. It has already seen billions in trading volume and continues to grow quickly. Kalshi also plans deep crypto integrations, work we’re excited to collaborate on, and today announced they’re expanding globally to 140 countries.
We’re not the only ones excited about the potential of prediction markets. For businesses and investors, event contracts can hedge risk, such as exposure to economic or policy changes. For policymakers and analysts, market prices offer real-time forecasts that can outperform polls and expert predictions. And for society at large, prediction markets create an open, transparent, and incentive-driven way to aggregate beliefs about the future.
This is the right moment for prediction markets. As trust in established institutions reaches historic lows — at least according to the polls — we need new systems that can earn trust in different ways. We believe the answer lies in open, decentralized systems. DeFi provides an alternative to traditional finance, stablecoins to conventional payment providers, and prediction markets to expert forecasts. Where people once trusted banks or pundits, they can now trust protocols and markets.
Hayek’s insight was that knowledge is too widely distributed for any one authority to possess. Instead, we need systems that harness the intelligence of the many. Kalshi puts this idea into action, transforming dispersed information into concrete, market-based forecasts. We’re excited to support their work as they bring prediction markets into the mainstream.
