Prediction Market Giant Polymarket Seeks $1B in Funding at $20B Valuation

According to a Bloomberg report, Polymarket is in negotiations with investors to raise $1 billion at a valuation of more than $20 billion. No deal has been completed yet, but the talks show how fast interest in prediction markets has grown. This comes just four months after completing a funding round at a $15 billion valuation.

Polymarket eyes bigger funding round

The company is reportedly speaking with potential investors on a new funding round worth $1 billion. The talks are said to be in their preliminary stage, according to Bloomberg. The new funding round could be worth more than the one seen in April,  where the firm raised capital at a $15 billion valuation at that time. 

Polymarket was founded in 2020 by Shayne Coplan. The platform allows users to buy "Yes" or "No" contracts on events like elections, crypto prices, sports, among others. Prices on bets change in real time on prediction markets as traders update their projections.

The company has seen strong business growth as demand for these kinds of offerings increases. Reports said its annualized revenue jumped over $1 billion after launching its regulated U.S. exchange. This platform was in the works from October 2025 before it was later launched in May 2026.

Daily trading volume on the U.S. platform has since then grown to over $100 million. The global version sees over $150 million in trades each day.

Competition from Kalshi strengthens

Polymarket has its wins, but rival Kalshi seems to be pulling ahead. Earlier this year, Kalshi completed a $1 billion funding round at a $22 billion valuation and could aim for an even higher valuation later.

Trading data also shows Kalshi currently leads the U.S. prediction market. In the past month, Kalshi leads with a monthly trading volume of $10.79 billion, followed by Polymarket at $3.08 billion, according to DeFiLlama.

It was also reported that Kalshi is exploring an IPO amid its rapid growth. 

Experts also expect prediction markets to keep growing. Bank of America and Bernstein estimate the sector could see $240 billion in trading volume during 2026. This is a 370% increase from 2025. They added that the market could reach $1 trillion in annual trading volume by 2030.

Regulation still creates uncertainty

Prediction market platforms are still facing regulatory challenges in the U.S. Polymarket’s U.S. exchange operates through QCX LLC, a federally approved contract market under the CFTC.

But despite this approval, some U.S. states are asking questions on if prediction contracts should be seen as a financial product or gambling.

In fact, a court just lifted a prediction market ban in Minnesota that could have hurt Polymarket and other businesses if it stood.

Nevada regulators, for instance, filed legal action to block certain services in the state. While some are looking to ban them, some are introducing exorbitant fees. 

North Carolina passed a law recognizing federally regulated prediction markets but implemented a 6% tax on trading fee revenue beginning in 2027. These legalities could affect how investors value the business in funding rounds.
