Key takeaway: Polymarket is a decentralised prediction market where traders purchase YES/NO shares on real-world events utilising USDC on the Polygon blockchain. All settlements are managed through smart contracts with no intermediary involvement.
What is Polymarket and how does it function? Fundamentally, Polymarket operates as a prediction marketplace: rather than wagering against a bookmaker's built-in edge, you exchange positions with fellow traders holding opposing views. Market prices continuously shift to reflect participants' collective assessment of likelihood — adjusting instantly as fresh information emerges.
The basics: prediction markets
In a prediction market, you acquire shares representing potential outcomes. Each share yields $1 upon a YES resolution, or $0 if the outcome is NO. When you purchase a YES share for 40 cents ($0.40), you're expressing the belief that this event has a 40% probability of occurring. Success means your capital doubles. Failure means your investment is forfeited.
Polymarket differs from conventional bookmakers by operating without a built-in margin (the "vig"). Pricing emerges purely from the interplay of supply and demand across the trader base.
How Polymarket uses blockchain
Polymarket operates atop the Polygon blockchain (a layer-2 scaling solution built on top of Ethereum). This architecture delivers:
- Complete transparency and on-chain verifiability of all activity
- Automated handling of account funding, trading execution, and settlement via smart contracts
- Prevention of fund seizure or outcome manipulation by Polymarket operators
- Near-instantaneous settlement within minutes rather than extended periods
USDC: the currency of Polymarket
Trading on Polymarket exclusively uses USDC (USD Coin), a stablecoin maintaining a 1:1 peg with the US dollar. Your account balance remains insulated from cryptocurrency price fluctuations — each USDC consistently equals $1 in value.
How markets resolve
Upon determination of an event's outcome, Polymarket employs the UMA Oracle (Universal Market Access) for market settlement. An assigned "proposer" presents the result; a 2-hour challenge period follows; if no objections arise, settlement becomes binding. Contested determinations are escalated to UMA token holders for decentralised resolution through voting.

Why Polymarket prices are accurate
Prediction markets have repeatedly demonstrated superior forecasting performance relative to conventional opinion surveys and specialist analysis. Throughout the 2024 US election period, Polymarket's probability assessments outperformed the majority of prominent polling organisations. The mechanism driving this accuracy: financial incentives compel participants to form rigorous, unbiased judgements.
