What to know
- Intercontinental Exchange announced on October 7, 2025, that it would invest up to $2 billion in cash in Polymarket.
- The deal valued Polymarket at roughly $8 billion before the investment.
- ICE gained the right to distribute Polymarket's event data to institutional investors worldwide.
Prediction markets spent years on the edge of finance. On October 7, 2025, the company that owns the New York Stock Exchange bought its way in.
Intercontinental Exchange, known as ICE, said it would invest up to $2 billion in cash in Polymarket, at a valuation of roughly $8 billion before the new money. ICE told shareholders the investment was not expected to materially affect its 2025 results.
What ICE got
Two things beyond the stake, according to its announcement:
- Data rights. ICE became a global distributor of Polymarket's event-driven data, including indicators of market sentiment, to institutional customers.
- A tokenization partnership. The two companies agreed to work together on future projects to put assets on blockchains.
Why the data was the point
An exchange operator makes much of its money selling market data. Prediction market prices are a new kind: a live number for the odds of an election result, a rate decision or a policy change. Trading desks already estimate those odds. ICE was betting they would pay for a traded price instead.
Why it mattered
The investment was a statement about legitimacy. A year earlier, prediction markets were best known for election betting and regulatory fights. After October 2025, the owner of the world's best-known stock exchange was a major shareholder in one.
It also raised the stakes of the industry's unresolved questions, including insider trading and the dispute over whether sports contracts are gambling. Those came to the surface in 2026, with a record Super Bowl, a push to stop campaign staffers trading on their own races, and new scrutiny after the midterms.
