It's been a huge few months for Polymarket. The prediction market operator has secured a $1 billion round at a $21 billion post-money valuation. That's a 40% valuation surge in just over four months.

That mega-raise aligns with fresh Wall Street projections from investment firm Bernstein, which forecasts that trading volume for prediction market apps will reach $240 billion in 2026 in the U.S., a 370% year-over-year expansion.

Polymarket's $1 billion capital injection, reported by Bloomberg, reflects unprecedented private equity demand for the booming event-contract trading market. 1789 Capital led the funding and committed about $300 million. Donald Trump Jr., a partner in 1789 Capital, is also a strategic advisor for Polymarket.

Late last year, Intercontinental Exchange (ICE), the parent company of the New York Stock Exchange, invested over $1.5 million in the company. ICE CEO Jeffrey Sprecher stated at the time that the partnership presented new opportunities for collaboration between traditional exchanges and emerging blockchain technologies.

Earlier this year, Polymarket closed a financing round at a $15 billion valuation, led by D.E. Shaw and G Squared. Polymarket is expected to use the new capital to expand its operational infrastructure, strengthen order book liquidity, and fund regulatory compliance initiatives.

While the 40% valuation surge is notable, it lags behind that of its closest competitor. Kalshi achieved a $22 billion valuation in May and is in discussions for fresh funding rounds based on a valuation of up to $40 billion.

A busy summer

Polymarket has been quite busy this summer, expanding its footprint and gearing up for the NFL season. Ahead of the NFL regular season starting Sept. 9, Polymarket has introduced "combos" to its North American platform. It has begun to beta test multi-leg parlay trades, with the first official beta combo completed on Aug. 5. Some competitors took this step last season, and it is likely to be a major source of trading volume this season.

The company struck a sponsorship agreement with the New York Yankees earlier in the month. That deal, which runs through the end of the MLB season, includes getting Polymarket branding on signage throughout Yankee Stadium, including LED displays that will run before and during home games.

Polymarket will also get a rotating spot on signage behind home plate during locally televised Yankees broadcasts on the YES Network and Prime Video.

The company has also inked a deal with On3, one of the largest college football media outlets in the country. As the exclusive prediction market partner, the company will weave its trading data into articles, videos, podcasts, newsletters, and social channels starting with the 2026 season.
