How Do Prediction Markets Work for Betting Operators?
Prediction markets allow betting operators to offer wagers on real-world events beyond sports — politics, crypto, entertainment, and more. Here's how operators integrate prediction market content and what the business model looks like.
Prediction markets enable users to bet on the outcomes of real-world events — "Will X happen by Y date?" — with odds reflecting the crowd's collective probability estimate. For betting operators, they represent a new revenue vertical that attracts a different player demographic than traditional sports betting or casino games.
What changed as of October 2026
- The market is far larger, and sports now lead it. Pew Research Center's analysis of data from The Block shows combined monthly trading volume on Kalshi and Polymarket rose from $26 billion in May 2026 to $53 billion in July 2026, and that sports is now the most traded topic on both platforms by a large margin.
- U.S. sportsbooks launched their own prediction products. FanDuel Predicts is the app of FanDuel Prediction Markets, a joint venture between FanDuel Group and CME Group; its contracts are listed on CME Group exchanges and regulated by the CFTC.
- European B2B feeds arrived. DATA.BET, a sportsbook supplier, launched Prediction Markets as a new vertical for operators on April 29, 2026, covering politics, geopolitics, finance, technology, crypto, economy, culture and weather.
- The U.S. legal line moved. The Ninth Circuit (August 28, 2026) and the Sixth Circuit (September 25, 2026) held that sports event contracts are likely sports bets rather than swaps, so states can apply gaming law to them; on October 9, 2026 the CFTC proposed a rule defining event contracts as swaps. For licensed operators outside the U.S. exchange model, the practical route remains offering event markets as fixed-odds bets under an existing betting licence.
How Operators Integrate Prediction Markets
There are two approaches:
1. Build In-House (Expensive)
Building prediction market infrastructure from scratch requires:
- Content generation pipeline (question creation, resolution criteria, probability calibration)
- Real-time pricing engine (an automated market maker such as LMSR, or fixed odds with a bookmaker margin)
- Automated resolution system (multi-source verification)
- Risk management framework
Cost: $500K-$2M+ | Timeline: 6-12 months | Ongoing maintenance: 3-5 engineers
2. API-First Content Feed (Fast)
Integrate a prediction market content feed that handles complexity:
- Curated questions from aggregated sources
- Real-time odds updates
- Automated resolution
- Built-in risk management
Cost: varies by vendor; monthly fees, revenue share or both | Timeline: days to a few weeks | Ongoing maintenance: Minimal
The Business Model
Prediction markets generate revenue through the spread between buy and sell prices (similar to a sportsbook margin). The margins and the revenue example below are illustrative assumptions, not measured industry benchmarks:
| Market Type | Gross Margin |
|---|---|
| Binary events | 5-10% |
| Multi-outcome | 8-15% |
| Long-duration | 10-20% |
For an operator with 50,000 monthly active users and 5% prediction market adoption rate:
- Monthly handle: ~$500,000
- Gross revenue (8% margin): ~$40,000/month
- Annual revenue: ~$480,000
The key advantage: these are incremental revenues from players already on your platform — zero additional acquisition cost.
What Categories Work Best
Based on volume data from active prediction platforms:
- Politics & elections — Historically the headline category (requires compliance review); since mid-2026 sports has been the most traded topic on Kalshi and Polymarket (Pew Research Center), but a licensed sportsbook already offers sports, so non-sports events are where a prediction feed adds new content
- Cryptocurrency — "Will Bitcoin hit $X by [date]?"
- Sports-adjacent — Transfer predictions, award winners, record-breaking events
- Entertainment — Awards shows, TV show outcomes, celebrity events
- Technology — Product launches, company milestones, AI developments
Getting Started
The fastest path for operators: integrate an API-based prediction market feed like Adkuu Pulse, a fixed-odds prediction-markets feed that sources questions from 5+ prediction platforms and regional news, delivers ready-to-use fixed odds priced with a margin the operator controls, and resolves markets automatically — all through a single real-time API. Because Adkuu Pulse is fixed-odds, it fits inside an operator's existing sports-betting licence; it is priced as a revenue share and goes live in days.
