01What it sells and who buys it
Polymarket operates prediction markets on real-world events. Traders buy and sell outcome contracts, while institutions and media can use the probabilities implied by market prices.
02How the business makes money
Trading and prediction-data distribution are distinct commercial activities. Fee eligibility and rates follow market-specific rules, so trading volume is not company revenue. The ICE agreement adds institutional distribution for prediction data.
03Marketing and customer acquisition
Trading produced probabilities that became news and then institutional data.

Create markets around real-world outcomes

Expand attention into financial data distribution

For institutional expansion, ICE agreed to distribute Polymarket data through its existing financial network. Retail trading participation and institutional data adoption are separate acquisition routes.

Financing the next stage

How the growth mechanism works
- Follow an event
- Participate in a market
- Share changing probabilities
- Distribute institutional data
Participation can make market prices more useful, while published probabilities attract attention back to the markets. Trading volume is not company revenue. The ICE partnership connects this activity to institutional data distribution, a different sales motion from acquiring individual traders.

More about the founding and key events
Shayne Coplan started Polymarket in 2020 as a prediction market for the outcomes of events. Prices formed by participants become information about possible outcomes. Distributing that information is also part of the business.
ICE’s investment included a partnership to distribute Polymarket data to institutional customers. Information produced on a trading platform gained a route into an established financial data network. The investment announcement alone does not quantify how much election-driven attention became lasting customer activity.
In 2025, ICE announced an agreement to invest up to $2 billion at an $8 billion pre-money valuation. It announced a further investment in 2026. Coplan, 27 in March 2026, was estimated to be worth $1 billion. Participation, liquidity and the uses of market data are central to this business. Market rules and geographic availability also shape its operations.
