Data Pipelines for Prediction Markets

A guide to indexing EVM-compatible chains with The Neighborhood, enabling unified data pipelines across Ethereum, Base, Arbitrum, and more.

Indexing Co powers real-time, high-precision data for prediction markets.

Prediction markets depend on perfect information. Whether you’re building something like Polymarket or Kalshi, running your own onchain venue, arbitraging markets across chains, or integrating external prediction feeds into an analytics product, the foundation is always the same: fast, clean, reliable data. Indexing Co delivers that data layer. Built on The Neighborhood, our distributed compute network, we index onchain and offchain market events with sub-second latency across 125+ chains. We stream liquidity changes, order flow, collateral movements, token transfers, settlement events, and user activity directly into your backend, dashboards, agents, or pricing models.

Why it matters for prediction markets:

Trading and Arbitrage

Latency determines edge. Firms running cross-market or cross-chain arbitrage need deterministic, high-speed indexing that doesn’t degrade when markets spike. Our dedicated Neighborhood nodes colocate with RPCs or validators to deliver the fastest possible feed. This setup is outperforming standard indexers or Subgraphs..

Your Own Prediction Market

If you're launching a new venue, you need more than block data. You need decoded events, stablecoin flows, oracle updates, and settlement logic delivered exactly as you define it. Our pipelines give you full control over transformations and schema, so you can design the mechanics of your market instead of fighting data infra.

Analytics & Insights Products

If you’re building dashboards, forecasting tools, or modeling engines, you need structured, query-ready data without ETL overhead. We transform raw network activity into clean streams you can plug directly into your warehouse, AI system, or API.

Integrating External Markets

Aggregators and research platforms that want to pull in Polymarket, Kalshi, or chain-native markets can unify everything through a single pipeline. Mix offchain APIs with onchain settlement and liquidity data in one transformation layer. Prediction markets thrive on clarity, speed, and truth. Indexing Co gives you all three with enterprise-grade reliability, customizable pipelines, and nodes tuned for sub-second performance. If you're building trading systems, arbitrage bots, new markets, or analytics on top of prediction-market data, we can power the full stack end-to-end.
