Best On-Chain Analytics Tools for Prediction Markets (2026)

On-chain analytics transform raw blockchain data into trading intelligence. For Polymarket traders, the right analytics tool can reveal which wallets are consistently profitable, when whales are accumulating, and where the smart money is flowing. Here are the 6 best tools ranked.

Polymarket settles every trade on the Polygon blockchain. This means the complete trading history of every participant — every buy, every sell, every position — is permanently recorded and publicly accessible. The raw data is there for anyone. The difference between average traders and consistently profitable ones often comes down to how effectively they analyze this data.

We evaluated each tool on analytical depth, ease of use, real-time capability, actionability (can you trade on insights directly?), and cost.

1. Polycool — Best for Actionable Analytics

Most analytics tools stop at showing you data. Polycool goes further: it analyzes on-chain data, surfaces the most profitable wallets, and lets you automatically copy their trades. It turns analytics into action.

Why It Ranks #1 for Actionable Analytics

The gap between "knowing" and "doing" is where most traders lose money. You might spend hours on Dune Analytics identifying a profitable whale, but by the time you set up monitoring and manually execute trades, the edge has evaporated. Polycool collapses this gap by integrating analytics, monitoring, and execution into a single workflow.

Analytics Features

• Wallet performance rankings — Wallets ranked by PnL, win rate, consistency, and trade frequency. Filter by time period and market category.
• Trade-level detail — See every trade a wallet has made, including entry price, exit price, market, and outcome.
• Market category analysis — Understand which categories (politics, crypto, sports) each wallet trades and where their edge is strongest.
• Convergence detection — Alerts when multiple tracked wallets independently take the same position, a strong signal of informed trading.
• One-tap execution — Go from analytics insight to live copy trading without switching platforms.

Considerations

Polycool's analytics are focused on wallet performance and copy trading use cases. If you need to run arbitrary SQL queries against raw blockchain data or build custom dashboards for non-trading research, a tool like Dune Analytics provides more flexibility. The ideal setup for serious traders is Polycool for daily monitoring and execution, supplemented by Dune for deep research.

2. Dune Analytics — Best for Custom Research

Dune Analytics is the gold standard for blockchain data analysis. It provides SQL access to decoded on-chain data from dozens of blockchains, including Polygon where Polymarket operates.

What Makes It Powerful

Dune decodes raw blockchain transactions into human-readable tables. Instead of parsing hex-encoded calldata, you can write SQL queries like "show me the top 50 wallets by Polymarket PnL in the last 90 days." The community has built hundreds of Polymarket-specific dashboards that you can use immediately or fork and customize.

Pros

• Full SQL access to all decoded Polymarket on-chain data
• Hundreds of community-built Polymarket dashboards
• Can answer virtually any analytical question about Polymarket activity
• Free tier available for basic queries and public dashboards
• Excellent for historical analysis and backtesting hypotheses

Cons

• Requires SQL knowledge for custom queries
• Not real-time — data refreshes on a schedule
• No trade execution capability
• No alerting on the free tier
• Paid plans ($349+/month) required for API access and faster refreshes
• Steep learning curve for complex queries

Dune is indispensable for serious on-chain research. Use it to identify patterns, validate hypotheses, and discover profitable wallets. Then use Polycool to act on those insights in real time. For query examples, see our on-chain analysis guide.

3. Nansen — Best for Cross-Chain Wallet Intelligence

Nansen is a professional-grade blockchain analytics platform known for its wallet labeling system and cross-chain coverage. It labels millions of wallets by type (fund, whale, smart money, DEX trader) and tracks their activity across multiple chains.

Polymarket Relevance

Nansen's Polygon coverage includes Polymarket activity. Its wallet labels can help you quickly identify whether a large Polymarket trader is a known fund, a DeFi whale, or a new wallet. The cross-chain view is useful for understanding a wallet's broader activity beyond just Polymarket.

Pros

• Professional wallet labeling — know who you are tracking
• Cross-chain coverage reveals a wallet's full activity profile
• Real-time alerts for tracked wallets
• Clean, intuitive interface
• Strong for identifying institutional and fund wallets

Cons

• Expensive — plans start at $150/month, with full features at $2,500+/month
• Polymarket-specific analytics are limited compared to Dune
• No trade execution capability
• Wallet labels for Polymarket-specific traders are sparse
• Overkill if you only trade on Polymarket

Nansen is valuable if you trade across multiple chains and want to understand the broader context of Polymarket whale wallets. For Polymarket-only analytics, Dune and Polycool provide better value.

4. Polygonscan — Best Free Transaction Explorer

Polygonscan is the official block explorer for Polygon. It shows every transaction, token transfer, and contract interaction for any wallet address on the network.

How to Use It for Polymarket Analytics

Enter any wallet address to see its complete transaction history. The "ERC-1155 Token Txns" tab shows Polymarket conditional token transfers (position entries and exits). The "Internal Txns" tab can reveal interactions with Polymarket's CLOB contracts.

Pros

• Completely free, no account required
• Shows every transaction — the ground truth of on-chain data
• Useful for verifying specific trades or auditing wallet claims
• Contract source code and ABI available for technical analysis

Cons

• Raw data only — no Polymarket-specific context or analytics
• Cannot calculate PnL, win rates, or performance metrics
• No alerting or monitoring features
• Impractical for tracking multiple wallets
• No execution capability

Polygonscan is a verification tool. Use it to confirm specific transactions or audit wallet activity you have identified through other analytics platforms.

5. Custom SQL Queries (Direct RPC / Subgraph)

For developers, querying Polymarket data directly via Polygon RPC endpoints or The Graph subgraphs provides the most flexibility and freshest data.

How It Works

You connect to a Polygon RPC provider (Alchemy, Infura, QuickNode) and query blockchain state directly, or use Polymarket's subgraph on The Graph for pre-indexed data. This approach lets you build custom analytics pipelines, real-time monitoring systems, and automated trading infrastructure.

Pros

• Real-time data — no refresh delays
• Complete flexibility in what you query and how you process it
• Can feed directly into automated trading systems
• No platform dependencies

Cons

• Requires strong programming and blockchain development skills
• Significant development time for useful analytics
• Must handle data decoding, indexing, and storage yourself
• RPC provider costs scale with query volume
• No pre-built dashboards or visualizations

Direct querying is the right approach for teams building production trading systems. Individual traders are better served by platforms that have already done the heavy lifting of data indexing and visualization.

6. Flipside Crypto — Best Alternative Analytics Platform

Flipside Crypto is a blockchain analytics platform similar to Dune, offering SQL access to decoded on-chain data with a focus on community-driven analysis and bounty programs.

Polymarket Relevance

Flipside covers Polygon data, which includes Polymarket activity. Its community bounty programs incentivize analysts to build dashboards and research, which means new Polymarket analytics content is regularly produced.

Pros

• Free tier with generous query limits
• Community bounties incentivize quality Polymarket analysis
• SQL-based querying similar to Dune
• Good documentation and learning resources

Cons

• Smaller Polymarket-specific community compared to Dune
• Fewer pre-built Polymarket dashboards
• Not real-time
• No trade execution capability
• Less mature data decoding for some Polymarket contracts

Flipside is a solid alternative to Dune, especially if you want to earn bounties for your analysis. For Polymarket-specific work, Dune currently has a larger community and more pre-built resources.

Building Your Analytics Stack

The most effective approach layers multiple tools:

• Daily monitoring and execution: Polycool for real-time wallet tracking, performance analytics, and automated copy trading.
• Deep research: Dune Analytics for custom queries, historical analysis, and pattern discovery.
• Verification: Polygonscan for auditing specific transactions and wallet claims.
• Broader context: Nansen for cross-chain wallet intelligence (if budget allows).

The key insight is that analytics alone do not make money — execution does. The best analytics stack is one that efficiently converts data into trades. That is why tools that bridge analytics and execution, like Polycool, deliver the most value for active traders. For more on turning data into trading signals, see our whale tracker page.
