Railbird Volume-Based Revenue Model

This pricing model only works if Railbird can keep trades cheap enough that people place lots of them, because the business gets paid a small cut every time users buy and sell contracts. That makes Railbird look more like an exchange than a media or subscription product. The core job is to maximize liquidity, tighten spreads, and keep capital turning over fast, especially in sports and other short duration markets where users can reuse the same dollars many times per week.

• A volume based model is standard for prediction exchanges. Kalshi charges retail traders an effective roughly 1% take rate on volume, while market makers trade free and can receive rebates, because deep order books matter more than charging access fees.

• The tradeoff versus sportsbooks is lower margin per bet, but much lower friction and broader reach. Prediction markets can price closer to true odds, while sportsbooks usually keep a 4% to 5% house edge. Lower fees make active traders more willing to churn capital repeatedly.

• The strongest comparable is the Kalshi and Polymarket split. Kalshi monetizes trading directly with regulated U.S. rails and higher operating costs. Polymarket pushed fees to zero to maximize liquidity, then added data monetization later. That shows how fee strategy shapes the whole business model.

Going forward, the winners in prediction markets are likely to be the venues that become the default place where order flow lands. For Railbird, that means revenue growth will come less from raising fees and more from stacking more markets, more market makers, and more distribution so daily trading volume compounds.
