Prediction Market Liquidity

A prediction market maker is a firm that continuously places buy and sell orders on prediction market contracts, ensuring that traders always have a counterparty when they want to enter or exit a position. Without market makers, platforms like Polymarket and Kalshi would have wide spreads, thin order books, and prices that don't reliably reflect the actual probability of an outcome. Institutional market makers like Raven use proprietary algorithms to price thousands of contracts simultaneously across categories like politics, sports, crypto, economics, and entertainment. By keeping spreads tight and books deep around the clock, market makers are what make prediction markets functional as both trading venues and forecasting tools.

Prediction markets are only useful as forecasting tools when their prices accurately represent the probability of an outcome. That accuracy depends entirely on liquidity. When a prediction market contract shows 62%, but the spread between the best bid and ask is 5 points wide, that number is unreliable and traders can't trust it. Dedicated liquidity providers solve this by maintaining consistent depth on both sides of every order book. This benefits platforms (more users, more credibility, more volume), traders (tighter execution, less slippage), and researchers or analysts who depend on prediction market data for decision-making. During high-volatility moments like election nights, breaking news events, or surprise economic announcements, institutional liquidity providers are especially critical because retail participants tend to withdraw, leaving markets thin exactly when accurate pricing matters most.

Prediction market platforms looking for institutional liquidity can reach out through our partnership inquiry form. Raven works with platforms to design liquidity provision programs tailored to their specific situation, whether that means bootstrapping deep liquidity for a brand new platform launch, strengthening order books across specific contract categories on an established venue, or providing dedicated market making for high-profile events. Our firm is backed by Hack VC, Wintermute Ventures, Coinbase Ventures, and CMCC Global. We currently provide liquidity on Polymarket, Kalshi, and Gemini Predictions, and are continuously evaluating new platforms as the prediction market ecosystem grows.

Prediction market platforms now cover a remarkably wide range of real-world events. The most popular categories include politics and elections (who will win a race, what policy will pass), sports (game outcomes, player performances, season results), economics (interest rate decisions, inflation numbers, jobs data), crypto (token prices, protocol milestones, regulatory actions), entertainment and pop culture (award shows, release dates, viral moments), weather, and breaking news events. Kalshi has reported that sports contracts now drive approximately 90% of its trading volume, while Polymarket remains strongest in politics and crypto-related markets. Raven provides market making across all of these categories, ensuring deep and reliable liquidity regardless of the event type.

Polymarket operates a central limit order book (CLOB) on the Polygon blockchain, where both individual traders and institutional market makers place orders. The deep, continuous liquidity that enables Polymarket's tight spreads across thousands of active markets comes primarily from institutional market making firms. These firms run algorithmic trading systems that quote buy and sell prices on hundreds or thousands of contracts at once, adjusting in real time as news breaks, polls shift, or market conditions change. Raven is one of the few institutional-grade firms actively providing liquidity across Polymarket, Kalshi, and Gemini Predictions simultaneously, using the same proprietary trading infrastructure that powers its market making on 30+ centralized and decentralized crypto exchanges.
