Prediction · the edge desk
Find the mispriced edge
Prediction markets price real-world outcomes — elections, the Fed, sports, crypto — as a live, money-weighted probability. This desk is where you find the edge: where Polymarket (global) and Kalshi (CFTC-regulated, US) disagree, which platform is worth your money, and the tools to price it yourself — process, never picks. As of July 2026.

All explainers →What is Polymarket?
Polymarket is a decentralized prediction market on Polygon, settling trades in USDC. Blocked for US users since a 2022 CFTC settlement, it processed $3.5B+ in volume during the 2024 US election.
What is Kalshi?
Kalshi is the first federally regulated prediction market in the U.S., operating under CFTC oversight since 2020. Trade real-money event contracts legally in all 50 states via ACH.
What are prediction markets?
Prediction markets let traders buy and sell binary event contracts priced by live auctions — not fixed odds. They're federally regulated by the CFTC, legal in all 50 US states, and distinct from traditional sportsbooks.
How do event contracts work?
Event contracts are binary derivatives priced as implied probabilities, settling at $1 or $0 based on real-world outcomes. They're traded on CFTC-regulated exchanges like Kalshi and CME.
Is Polymarket legal in the United States?
Polymarket has been legally inaccessible to U.S. residents since a January 2022 CFTC settlement. Here's what that means for U.S. users and what legal alternatives exist.
What is Manifold Markets?
Manifold is a prediction-market platform where users create markets and trade with play-money "mana", making it a low-stakes way to forecast almost anything.
