Polymarket Insiders Glossary
A comprehensive reference of prediction market and on-chain analysis terminology. Bookmark this page — you'll come back to it.
A–C
Accumulation
The process of gradually building a position over time through multiple smaller purchases, rather than buying all at once. Whales accumulate to minimize price impact and avoid detection. Identifying early-stage accumulation is one of the most valuable skills in on-chain analysis. See our smart money signals guide for accumulation detection techniques.
Arbitrage
Profiting from price differences for the same outcome across different platforms or related markets. For example, buying "YES" at 45 cents on Polymarket while selling the equivalent at 48 cents on Kalshi locks in a 3-cent risk-free profit. Cross-platform arbitrage helps keep prediction markets efficient.
Calibration
A measure of how accurately a prediction market's prices reflect true probabilities. A well-calibrated market means that outcomes priced at 70% actually occur approximately 70% of the time. Polymarket's political markets have historically shown strong calibration, while newer or lower-volume markets tend to be less calibrated.
Conditional Token Framework (CTF)
The smart contract system Polymarket uses to represent market outcomes as tradeable tokens. Each outcome in a market is an ERC-1155 token that's worth $1 if the outcome resolves YES and $0 if it resolves NO. The CTF enables trustless settlement — no intermediary decides who gets paid.
Convergence
When multiple independently profitable wallets take the same position in a market within a short timeframe. Convergence is one of the strongest smart money signals because it represents agreement among traders with different strategies and information sources. Three-wallet convergence has historically preceded correct outcomes roughly 72% of the time on Polymarket.
Copy Trading
The practice of automatically replicating the trades of a selected wallet or set of wallets. On Polymarket, copy trading is enabled by on-chain transparency — you can see exactly what any wallet buys or sells and mirror those trades. Effective copy trading requires careful wallet selection and risk management.
D–H
Dune Analytics
A blockchain analytics platform that provides SQL access to decoded on-chain data. For Polymarket analysis, Dune enables querying wallet performance, market volume, trade history, and custom metrics. It's the primary tool for systematic on-chain research. See our on-chain analysis guide for Dune query examples.
Edge
The difference between a trader's estimated probability and the market price. If you believe an outcome has a 65% probability but the market prices it at 55%, you have a 10-point edge. Consistent profitability requires finding and exploiting edges while managing the variance inherent in probabilistic outcomes.
Funding Chain
The sequence of transactions through which a wallet received its initial capital. Tracing funding chains is a primary technique for wallet clustering — wallets funded from the same source are likely controlled by the same entity. Sophisticated operators use exchanges and mixers to obscure funding chains.
Gas (MATIC)
The transaction fee required to execute operations on the Polygon blockchain. Every Polymarket trade requires a small amount of MATIC for gas. While gas costs on Polygon are minimal (fractions of a cent), gas payment patterns can be used in wallet clustering analysis to identify related wallets.
Hedge
A position taken to offset potential losses from another position. On Polymarket, hedging often involves buying correlated outcomes across different markets. For example, a trader long on "Democrats win presidency" might hedge by buying "Republicans win Senate" to protect against scenarios where their primary thesis is wrong but a related outcome partially compensates.
I–M
Informed Flow
Trading volume generated by wallets with historically demonstrated edge — as opposed to noise flow from uninformed participants. The ratio of informed flow to total flow in a market is a leading indicator of price discovery. Markets with rising informed flow ratios are likely to experience directional price moves.
Kelly Criterion
A mathematical formula for optimal position sizing based on edge and odds. The Kelly formula recommends betting a fraction of your bankroll equal to (edge / odds). Most professional traders use fractional Kelly (25-50% of the full Kelly recommendation) to reduce variance at the cost of slightly lower expected returns.
Liquidity
The depth of buy and sell orders available in a market at various price levels. High liquidity means you can enter and exit large positions without significantly moving the price. Low liquidity means even small trades can cause meaningful price impact. Polymarket liquidity varies dramatically by market — popular political markets are deep, while niche markets can be very thin.
Market Maker
A participant who provides liquidity by continuously placing both buy and sell orders, profiting from the bid-ask spread. Market makers are essential for market functioning but their trades are not directionally informative — they buy and sell roughly equally. Filtering out market maker activity is important for accurate signal detection.
Mispricing
When a market's price doesn't accurately reflect the true probability of an outcome. Mispricings are the source of all trading edge. They occur due to retail sentiment bias, slow information processing, low liquidity, or complex conditional probabilities that participants struggle to evaluate correctly.
N–R
Neg Risk Exchange
Polymarket's contract for trading complementary outcomes (YES/NO pairs) efficiently. The Neg Risk Exchange allows traders to take positions on the "No" side of markets without directly buying NO tokens, instead using a mechanism that's capital-efficient for both sides of the trade.
On-Chain
Refers to data and activity recorded on a blockchain. On Polymarket, "on-chain" means the trade data is permanently stored on the Polygon blockchain and publicly accessible. On-chain analysis is the practice of extracting trading intelligence from this blockchain data.
Order Flow
The stream of buy and sell orders entering a market. Analyzing order flow reveals the intentions and behavior of market participants. On Polymarket, order flow is fully transparent on-chain, enabling detailed analysis of who is buying, who is selling, at what sizes, and at what times.
PnL (Profit and Loss)
The total profit or loss generated by a wallet's trading activity. On Polymarket, PnL is calculated by comparing the cost of acquiring positions against the resolution value (or sale price) of those positions. Cumulative PnL over many trades is the primary metric for evaluating wallet quality.
Resolution
The process by which a Polymarket market is settled — the outcome is determined and winning positions are paid out. Resolution can be based on official data sources, oracle reports, or UMA's optimistic oracle system. Understanding resolution criteria is essential for avoiding disputes and edge cases.
S–Z
Slippage
The difference between the expected price of a trade and the actual execution price. Slippage occurs when a market order consumes available liquidity at the best price and fills at progressively worse prices. Large orders in low-liquidity markets experience the most slippage. Using limit orders eliminates slippage risk.
Smart Money
A collective term for traders who consistently demonstrate edge — better information, faster processing, or superior analytical models. On Polymarket, smart money is identified by historical PnL, win rate, and consistency across market categories. Tracking smart money activity is the foundation of insider wallet analysis.
Spoofing
A manipulation tactic involving placing large orders with no intention of execution, designed to create a false impression of supply or demand. Spoofers place visible orders to influence other traders' behavior, then cancel before the orders fill. See our market manipulation guide for detection techniques.
Sybil Attack
Creating multiple fake identities (wallets) to gain disproportionate influence in a system. On Polymarket, Sybil attacks can inflate volume metrics, create false convergence signals, or game reward systems. Sybil detection uses wallet clustering techniques to identify wallets controlled by the same entity.
Wash Trading
A form of market manipulation where a single entity trades with themselves across multiple wallets to artificially inflate volume. Wash trading creates the illusion of market activity and interest where none genuinely exists. Detection relies on funding chain analysis, timing correlation, and behavioral fingerprinting.
Whale
A wallet with significant capital deployed on Polymarket — typically $50,000+ across active positions. Whales have outsized influence on market prices, and their trading activity is closely watched by other participants. Not all whales are profitable — the term refers to capital size, not skill. See our whale tracker for detailed analysis.
Win Rate
The percentage of a wallet's resolved positions that were profitable. A win rate above 55% over 100+ trades suggests genuine edge rather than luck. However, win rate alone is insufficient — a wallet with a 90% win rate that loses 10x on each loss is not profitable. Win rate must be evaluated alongside average win size and average loss size.
