Abstract

This research analyzes Polymarket, the leading crypto-native prediction market platform built on Polygon. We examine how Polymarket unique characteristics—blockchain settlement, global accessibility, and crypto-native user base—create distinct market dynamics compared to regulated alternatives. Through analysis of historical accuracy, liquidity patterns, and participant behavior, we identify systematic mispricing opportunities and develop frameworks for trading on decentralized prediction markets.

Key Takeaways

Polymarket is where prediction markets meet DeFi—bringing both the innovation and the chaos of crypto to forecasting.

The absence of position limits on Polymarket means that when you are right, you can be very right. When you are wrong, you can be very wrong.

Crypto-native traders bring different biases to prediction markets—understanding these biases is the key to finding edge.

On Polymarket, the biggest risk is not being wrong about the event—it is smart contract risk, regulatory risk, and liquidity risk.

Problem Statement

Polymarket has emerged as the dominant crypto-native prediction market, processing billions of dollars in trading volume on political, crypto, and cultural events. Unlike regulated platforms like Kalshi, Polymarket operates on blockchain infrastructure (Polygon) with USDC settlement, enabling global participation without position limits or KYC requirements. This structure attracts a distinct participant base—crypto-native traders, DeFi users, and international participants excluded from US-regulated markets. This research investigates: How do Polymarket unique characteristics affect price discovery and market efficiency? What systematic biases exist among crypto-native prediction market participants? How can traders identify and exploit mispricing while managing platform-specific risks?

Frequently Asked Questions

What is Polymarket and how does it work?

Polymarket is a decentralized prediction market platform built on Polygon blockchain. Traders buy and sell event contracts using USDC stablecoin, with contracts paying $1 if an event occurs and $0 if it does not. Unlike regulated platforms, Polymarket operates globally without position limits or KYC requirements, enabling permissionless participation through crypto wallets.

How accurate are Polymarket predictions?

Polymarket demonstrates strong accuracy for high-liquidity political events, often matching or exceeding traditional polling. However, accuracy varies significantly by event type and liquidity. Crypto-related events may reflect crypto-native biases, while low-liquidity markets can exhibit significant mispricing. Polymarket prices tend to be more volatile than Kalshi for identical events.

Is Polymarket legal in the United States?

Polymarket legal status in the US is uncertain. The platform operates offshore and does not require KYC, but US residents may face legal risks. In 2022, Polymarket settled with the CFTC and agreed to block US users, though enforcement is limited. US traders should consult legal counsel before participating.

What are the risks of trading on Polymarket?

Polymarket carries several unique risks: (1) Smart contract risk—bugs could result in loss of funds; (2) Regulatory risk—platform could be shut down or restricted; (3) Oracle risk—disputed resolutions could affect payouts; (4) Liquidity risk—thin markets may prevent exit at fair prices; (5) Counterparty risk—no SIPC insurance or regulatory protection.

How does Polymarket compare to Kalshi?

Polymarket is crypto-native (USDC on Polygon), globally accessible, has no position limits, and attracts speculative traders. Kalshi is CFTC-regulated, US-based, uses USD, and has position limits. Polymarket offers higher liquidity for some events and more flexibility, but carries regulatory and smart contract risks. Prices often diverge between platforms, creating arbitrage opportunities.

How do I start trading on Polymarket?

To trade on Polymarket: (1) Set up a crypto wallet (MetaMask or similar); (2) Acquire USDC on Polygon network; (3) Connect wallet to Polymarket; (4) Browse markets and place trades. No KYC is required, but you need basic familiarity with crypto wallets and DeFi. Start with small positions to understand the platform mechanics.

Key Concepts

Polymarket
A decentralized prediction market platform built on Polygon blockchain, using USDC for settlement. Polymarket enables global participation in event contracts without position limits or traditional KYC requirements.
USDC Settlement
Polymarket contracts are denominated and settled in USDC (USD Coin), a stablecoin pegged to the US dollar. This enables crypto-native trading while maintaining dollar-denominated pricing.
Polygon Network
A Layer 2 scaling solution for Ethereum that provides faster and cheaper transactions. Polymarket uses Polygon to enable low-cost trading while maintaining Ethereum security.
Smart Contract Risk
The risk that bugs or vulnerabilities in Polymarket smart contracts could result in loss of funds. Unlike regulated exchanges, there is no SIPC insurance or regulatory recourse.
Liquidity Provider
Participants who provide capital to Polymarket markets, earning fees from trading activity. Liquidity provision on Polymarket involves different dynamics than traditional market making.
Resolution Oracle
The mechanism by which Polymarket determines event outcomes. Polymarket uses UMA optimistic oracle for decentralized resolution, with dispute mechanisms for contested outcomes.

Competing Explanatory Models

Crypto-Native Efficiency Model

Polymarket permissionless structure enables superior price discovery by removing barriers to participation. Global access, no position limits, and 24/7 trading allow information to be incorporated faster than regulated alternatives. The model predicts that Polymarket prices are more accurate than Kalshi for events with global interest.

Crypto Speculation Model

Polymarket attracts crypto-native traders who bring speculative biases from cryptocurrency markets. These participants may overweight tail risks, exhibit momentum-chasing behavior, and have different loss aversion than traditional traders. The model predicts systematic mispricing driven by crypto-native behavioral patterns.

Regulatory Arbitrage Model

Polymarket primary value is enabling trading that regulated platforms cannot offer—either due to event restrictions or participant exclusions. Prices reflect the marginal trader who cannot access alternatives, not necessarily the most informed view. The model predicts that Polymarket prices diverge from Kalshi when participant composition differs significantly.

Liquidity Fragmentation Model

Prediction market efficiency depends on liquidity concentration. Polymarket and Kalshi fragment liquidity across platforms, reducing efficiency on both. The model predicts that neither platform achieves optimal price discovery, and that cross-platform arbitrage opportunities persist due to fragmentation.

Verifiable Claims

Polymarket processed over $1 billion in trading volume during the 2024 US presidential election cycle.

Noise Model

This research analyzes a rapidly evolving platform with significant regulatory and technical uncertainties.

  • Polymarket regulatory status is uncertain and may change
  • Smart contract risks are difficult to quantify
  • Crypto market conditions affect Polymarket liquidity unpredictably
  • Participant composition may shift as the platform evolves
  • Historical data is limited and may not reflect future dynamics
  • Cross-platform comparisons are complicated by different market structures

Implications

These findings suggest that Polymarket offers unique trading opportunities for participants comfortable with crypto-native infrastructure and associated risks. The most promising strategies focus on: (1) exploiting behavioral biases specific to crypto-native traders, (2) cross-platform arbitrage with Kalshi when prices diverge, (3) providing liquidity in underserved markets, and (4) trading around crypto market events that affect Polymarket participant behavior. However, traders must carefully manage smart contract risk, regulatory uncertainty, and the correlation between crypto markets and prediction market liquidity. Polymarket is not suitable for risk-averse traders or those requiring regulatory protection.
