Polymarket Reportedly in Talks to Raise $1 Billion at Over $20 Billion Valuation

Polymarket is in preliminary discussions with potential investors aimed at raising approximately $1 billion at a valuation exceeding $20 billion, according to a Bloomberg report published Aug. 4 that cited individuals familiar with the private negotiations.

No deal has been formally announced, and a Polymarket spokesperson declined to comment when contacted about the report. The proposed fundraising amount, valuation, and participating investor group should accordingly be regarded as preliminary rather than finalized terms.

If completed, the round would bring Polymarket's valuation close to that of Kalshi, its principal prediction market competitor, which attained a $22 billion valuation in May. It would also extend a broader surge in private valuations across a prediction market industry that has grown well beyond election contracts to encompass sports, economics, crypto, and other real-world events — a category that has attracted both retail and institutional interest as event contracts gain visibility as a distinct asset class.

Funding Discussions at an Early Stage

The reported transaction remains in its initial phases. No term sheet, closing date, or definitive investor roster has been disclosed. As with any private financing, the terms — including total capital raised and the valuation investors ultimately agree upon — are subject to change prior to completion.

Comparisons with Polymarket's October 2025 valuation warrant some caution. Bloomberg referenced a figure of roughly $9 billion. Intercontinental Exchange's (ICE) official announcement, however, stated that its planned investment reflected an approximate $8 billion valuation on a pre-money basis. The discrepancy may stem from different valuation methodologies and is not necessarily contradictory.

Details surrounding the April financing round similarly blend reported and confirmed information. Bloomberg reported that Polymarket raised approximately $1 billion at a $15 billion valuation, with D.E. Shaw and G Squared joining as new investors. ICE separately confirmed an additional $600 million investment on March 27 as part of a Polymarket equity raise. The New York Stock Exchange parent had previously committed $1 billion in October 2025. ICE did not disclose the valuation associated with its March investment.

A valuation above $20 billion would represent an increase of at least 33% over the reported April figure and more than double the valuation Bloomberg attributed to Polymarket's October round.

U.S. Expansion Underpins the Valuation Thesis

Polymarket's re-entry into the U.S. market provides the company with a regulated growth channel to complement its international platform, which operates using crypto-based settlement. ICE's involvement brings the backing of one of the world's largest exchange operators, lending Polymarket institutional credibility and infrastructure expertise as it transitions from an offshore crypto-native platform to a federally regulated U.S. exchange.

The CFTC's official registry lists QCX LLC, operating as Polymarket US, as a designated contract market, with a recorded designation date of July 9, 2025. The exchange has since submitted multiple rule changes covering areas such as fees, liquidity programs, market surveillance, and trading procedures.

Bloomberg reported that Polymarket launched its U.S. exchange following its April financing. The company's own U.S. access page notes that its application is being gradually released to users from a waitlist, suggesting that availability may still be expanding in phases rather than being universally accessible.

Revenue growth forms another component of the valuation argument, though the figures remain private company metrics. Bloomberg's sources indicated that Polymarket's annualized revenue had more than tripled since April, surpassing $1.2 billion. Reuters separately reported in June that the platform's annualized revenue had exceeded $1 billion. An annualized figure projects recent performance over a full year and is not equivalent to audited revenue for a completed fiscal period.

Trading activity data further illustrates the U.S. venue's acceleration. As crypto.news reported, Polymarket, Polymarket US, and Kalshi generated a combined $50.6 billion in July volume — a record total. Kalshi accounted for $37.7 billion of that figure. Polymarket US grew its volume by 54% to $5 billion, while Polymarket's international venue declined 26% to $7.9 billion. The data signals faster U.S. growth, though it also indicates that the broader Polymarket business is not expanding uniformly.

Kalshi Sets a High Competitive Bar

Kalshi formally announced a $1 billion Series F round at a $22 billion valuation on May 7. Coatue led the financing, with participation from Sequoia Capital, Andreessen Horowitz, IVP, Paradigm, Morgan Stanley, and ARK Invest.

Kalshi reported that its institutional trading volume had risen 800% over a six-month period and that annualized trading volume climbed from $52 billion to $178 billion. These are company-provided trading figures and should not be conflated with revenue.

In related reporting, crypto.news noted that Kalshi claimed over 90% of U.S. prediction market activity at the time of its funding announcement. Independent July data also showed Kalshi processing nearly three times the combined volume of Polymarket's international and domestic venues.

Polymarket's reported target would narrow the valuation gap with Kalshi despite the latter's substantially higher trading volume. Prospective investors may be factoring in Polymarket's international footprint, crypto settlement infrastructure, brand recognition, and strategic partnership with ICE. Trading volume alone does not determine a private company's valuation. Fee structures, customer retention, compliance costs, market composition, and post-event activity levels following major sporting or political events all influence revenue quality. Notably, July open interest declined after the conclusion of the World Cup even as monthly trading volume set a record.

Regulatory Disputes May Shape Investor Sentiment

Although Polymarket US holds a federal designation, several states contend that sports-based event contracts constitute gambling and remain governed by state law.

In January, the Nevada Gaming Control Board filed a civil complaint against Polymarket and QCX, requesting that a state court bar the companies from offering what the regulator characterized as unlicensed wagering within Nevada.

As previously reported, Polymarket and Kalshi are also embroiled in a wider dispute over whether the Commodity Exchange Act grants the CFTC exclusive regulatory authority over federally registered event contract platforms. The jurisdictional question carries industry-wide implications: a definitive resolution — whether through litigation, legislation, or regulatory rulemaking — could determine how broadly event contracts can be offered across U.S. states and set precedents for future product categories at the intersection of financial markets and gaming regulation.

North Carolina has taken a divergent approach. A law enacted in July formally recognizes CFTC-regulated prediction markets and imposes a 6% tax on trading fee revenue starting in 2027.

These legal and regulatory conflicts do not preclude Polymarket from pursuing financing discussions. They could, however, influence market access, legal expenditures, and how investors ultimately assess the value of the company's U.S. expansion strategy.
