Oddpool Raises $3M Seed for Prediction Market Data Infrastructure
Oddpool Raises $3M Seed Round
Oddpool, an institutional data infrastructure provider for prediction markets, has raised $3 million in Seed funding. The round was backed by Y Combinator.
What Oddpool Does
Oddpool builds data infrastructure aimed at institutional participants in prediction markets. According to the company, its platform gives quant funds, prop shops, market makers, and hedge funds unified access to every venue through a single API. The company currently covers Kalshi and Polymarket.
The platform captures every trade and order-book update under universal tickers. On top of that data layer, Oddpool offers:
- Tick-level historical depth for backtesting
- Real-time whale-trade tracking
- Cross-venue arbitrage detection
The core proposition is consolidation: rather than integrating separately with each prediction market venue, institutional users can access normalized, tick-level data through one interface. For quantitative funds and market makers, that kind of unified historical and real-time feed is a prerequisite for systematic trading and research in the prediction market space.

Company Background
Oddpool was founded in 2026 by Avi Arora and Ritesh Malpani. The company went through Y Combinator's Spring 2026 batch, and Y Combinator is listed among the investors in this Seed round.
The company operates at oddpool.com.
Why It Matters
Prediction markets have grown into a distinct venue category, with Kalshi and Polymarket among the most prominent platforms. As institutional interest in these venues increases, demand rises for the data plumbing that professional trading firms expect: consistent tickers, complete order-book history, and the ability to monitor activity across venues simultaneously.
Oddpool's positioning is squarely in that infrastructure layer rather than in trading or market-making itself. That places it alongside other institutional data providers that sell normalized market data and analytics to funds, though Oddpool's focus is specifically on prediction markets.
What to Watch
The Seed round gives Oddpool capital to build out its data coverage and institutional offering. Key questions for the company's next phase include how quickly it expands beyond its current venue coverage of Kalshi and Polymarket, how it deepens its historical data set, and how it converts quant funds and market makers from evaluation into paying institutional customers.
For observers of prediction market infrastructure, Oddpool represents an early-stage bet that the venue category will mature into one that demands the same caliber of data tooling as traditional asset classes.
