Polymarket is in talks to raise $400 million at a $15 billion valuation, according to a report by The Information. The report cited two people familiar with the matter. If completed, the new Polymarket funding round would add to the recent flow of capital into prediction markets.
Even at $15 billion, the reported Polymarket valuation would remain below the Kalshi valuation in its latest funding round. That round valued Kalshi at about $22 billion. Still, the reported deal shows that major investors continue to back firms tied to event-based trading.
The report also said Polymarket wants to add more strategic investors beyond Intercontinental Exchange, or ICE. Moreover, the broader round could reportedly reach $1 billion. That detail places the possible Polymarket funding round among the larger reported capital raises in the sector.
Polymarket valuation rises as prediction markets pull in more capital
The reported Polymarket valuation comes after another major investment in the company. In late March, ICE, the parent company of the New York Stock Exchange, invested $600 million into Polymarket. That deal added another large institutional name to the company’s backers.
At the same time, prediction markets have drawn more investor attention across the sector. The gap between the Polymarket valuation and the Kalshi valuation shows where investors currently place the two platforms. However, both figures point to the same trend: capital continues moving into this market.
According to the report, prediction markets now record more than $10 billion in monthly trading volume. That activity started rising around the 2024 US election. Since then, trading has spread into sports, political races, company results, and cultural events. As a result, firms in the space are attracting more funding and more attention.
Prediction markets draw Wall Street firms beyond Polymarket and Kalshi
The growth in prediction markets has also brought in traditional finance firms. In early March, Nasdaq MRX, one of Nasdaq’s options exchanges, filed to offer cash-settled, binary-style contracts on the Nasdaq-100 index. That move showed how regulated exchanges are entering adjacent areas of event-based trading.
Meanwhile, Cboe Global Markets is also launching a prediction market-style product. In addition, CME Group partnered with US gambling company FanDuel. That partnership will allow traders to bet on markets outside finance. Therefore, the sector is expanding across both financial and non-financial events.
Last week, Charles Schwab and Citadel Securities also said they are weighing a move into prediction markets. That matters because it shows the sector is no longer limited to crypto-native platforms. Instead, larger financial firms are now studying the space as trading volume grows.
Prediction market regulation remains a key issue for the sector
Despite the growth, prediction market regulation remains unsettled. Kalshi and other firms have faced scrutiny over allegations of insider trading and market manipulation. These legal issues continue to follow the sector as activity rises.
At present, Kalshi is in a court fight with the Nevada Gaming Control Board. A lower court temporarily blocked Kalshi from operating in the state. Nevada regulators argue that the company’s contracts amount to unlicensed gambling.
The case could shape the future of prediction market regulation in the United States. Coinbase chief legal officer Paul Grewal said the dispute could reach the US Supreme Court. If that happens, the case could help define how US regulators treat prediction markets, gambling products, and event-based derivatives.
