# Polymarket

## Overview
Crypto-native prediction market platform on Polygon. Users trade binary outcome contracts on real-world events (politics, economics, sports, crypto). Built on USDC. Vindicated by 2024 US presidential election — called Trump victory when polls showed a toss-up. Now the world's largest prediction market by volume.

## Current State
- **Volume**: $390M 24h, $2.6B 7-day, $8.7B 30-day (March 2026)
- **Accuracy**: 94%+ one month before outcome resolution; 98% on calling winners
- **US access**: Returned to US users (invite-only, restricted markets) after CFTC approved Amended Order of Designation (November 2025). Operating as intermediated contract market with full reporting/surveillance.
- **Valuation**: ICE (Intercontinental Exchange) invested up to $2B, making founder Shayne Coplan the youngest self-made billionaire.
- **Market creation**: Permissionless — anyone can create markets (differentiator vs Kalshi's centrally listed model)

## Timeline
- **2020-06** — Founded by Shayne Coplan (age 22, NYU dropout). Pivoted from earlier DeFi project Union Market.
- **2022-01** — CFTC fined Polymarket $1.4M for operating unregistered binary options market; ordered to cease and desist. Blocked US users.
- **2024-11** — 2024 US presidential election: $3.7B total volume. Polymarket correctly predicted Trump victory; polls showed toss-up. Major vindication moment for prediction markets.
- **2025-10** — Monthly volume exceeded $3B
- **2025-11** — CFTC approved Amended Order of Designation as regulated contract market
- **2025-12** — Relaunched for US users (invite-only, restricted markets)
- **2026-03** — Combined Polymarket+Kalshi weekly record: $5.35B (week of March 2-8, 2026)

## Competitive Position
- **#1 by volume** — leads Kalshi on 30-day volume ($8.7B vs $6.8B)
- **Crypto-native**: USDC on Polygon, non-custodial, permissionless market creation
- **vs Kalshi**: Kalshi is regulation-first (USD-denominated, KYC, traditional brokerage integration). Polymarket is crypto-first. Both grew massively post-2024 election — combined 2025 volume ~$30B.
- **Not governance**: Polymarket aggregates information but doesn't govern organizations. Different use case from MetaDAO's futarchy. Same mechanism class (conditional markets), different application.

## Investment Thesis
Polymarket proved prediction markets work at scale. The 2024 election vindication created a permanent legitimacy shift — prediction markets are now the reference standard for forecasting, not polls. Growth trajectory accelerating. Key risk: regulatory capture (CFTC constraints on market types), competition from Kalshi on institutional/mainstream side.

**Thesis status:** ACTIVE

## Relationship to KB
- [[Polymarket vindicated prediction markets over polling in 2024 US election]] — core vindication claim
- [[speculative markets aggregate information through incentive and selection effects not wisdom of crowds]] — mechanism theory Polymarket demonstrates
- [[decision markets fail in three systematic categories where legitimacy thin information or herding dynamics make voting or deliberation structurally superior]] — boundary conditions apply to Polymarket too (thin-information markets showed media-tracking behavior during early COVID)
