Polymarket Secures $1 Billion Round at $21 Billion Valuation Led by 1789 Capital, Trailing Kalshi by Narrow Margin
TL;DR — Polymarket is raising $1B at a $21B valuation led by 1789 Capital, with Donald Trump Jr. as a partner. The deal narrows the gap to Kalshi’s $22B valuation amid record trading volumes that reached $12.1B weekly. Legal circuit splits and integrity probes continue to cloud the sector’s path forward.
SCCG Take — Investor capital continues to flow into prediction markets on growth expectations, yet unresolved CFTC-state jurisdiction fights and integrity referrals create material execution risk until federal clarity emerges.
Polymarket is raising $1 billion in funding at a reported $21 billion valuation. The round is led by 1789 Capital, which includes Donald Trump Jr. among its partners. The venture firm is expected to invest roughly $300 million now after committing about $200 million previously, for a total stake near $500 million. The deal would lift the company’s valuation from roughly $15 billion.
This places Polymarket just behind rival Kalshi at $22 billion. Kalshi reached that mark after a $1 billion Series F in May led by Coatue, with participation from Sequoia Capital, Andreessen Horowitz, IVP, Paradigm, Morgan Stanley and ARK Invest. According to the New York Times and Wall Street Journal, the transactions reflect sustained investor appetite for prediction markets despite active litigation and integrity concerns.
Surging Trade Volumes Support High Valuations
Combined weekly notional trading volume for Kalshi and Polymarket reached $12.1 billion, per DeFi Rate. Broader monthly prediction-market volume expanded from about $1.2 billion in early 2025 to more than $20 billion by January 2026, according to TRM Labs. Polymarket alone recorded $425 million in daily volume on Feb. 28.
Sports events remain central. Since July 2024, sports has represented about 80% of Kalshi’s total volume and 39% of Polymarket’s.
Legal Classification and Integrity Issues Pose Limits
The funding arrives while the regulatory status of prediction markets stays unresolved. Kalshi is litigating in multiple states over whether sports event contracts are CFTC-regulated derivatives or unlicensed sports betting. The Ninth Circuit ruled for Nevada that Kalshi’s contracts were likely sports bets rather than swaps. The Third Circuit previously sided with Kalshi in New Jersey. The split makes Supreme Court review more likely, with New York, Connecticut, Utah and Michigan among states pursuing enforcement. The Commodity Futures Trading Commission asserts exclusive federal authority.
Polymarket has faced separate scrutiny over alleged deceptive social media marketing and potential insider trading tied to military information. The company has referred more than 90 accounts to law enforcement and maintains policies against trading on material nonpublic information.
These legal and integrity questions will determine whether the platforms can scale nationally without adopting the state-by-state licensing framework required of sportsbooks. Resolution at the Supreme Court or through legislation would remove a primary obstacle to the growth investors are now pricing in.
