Polymarket plans to Capital $400 million at a valuation of $15 billion.

According to The Information , Polymarket – a decentralized prediction market platform – is in negotiations to raise an additional $400 million at a valuation of approximately $15 billion.

This Capital round follows reports from October, when Polymarket was reportedly in talks with investors about raising additional funds at a valuation of $12–15 billion.

The Information reported in October that Polymarket was Capital at approximately $9 billion after ICE – the parent company of the NYSE – agreed to invest up to $2 billion. The new funding, if finalized, would add to the $600 million that ICE had already committed.

The report also stated that Polymarket wants to invite additional strategic investors beyond ICE, and the total Capital size could be raised to $1 billion.

Recently, both Polymarket and its rival Kalshi have attracted significant attention from investors. Kalshi, in particular, is believed to have raised over $1 billion in March at a valuation of $22 billion, nearly double its November valuation.

In terms of activity, Kalshi and Polymarket remain the two leading platforms. In March, Kalshi recorded approximately $13 billion in monthly Volume , while Polymarket recorded around $10.57 billion.

Nevertheless, the prediction market is facing increasing regulatory pressure. Last month, both Kalshi and Polymarket had to increase measures to limit insider trading risks as US lawmakers pushed for stricter regulation of prediction markets.

In March, Senators Adam Schiff and John Curtis proposed the “Prediction Markets Are Gambling Act,” which would ban the listing/trading of sports-related or casino-style prediction contracts on registered platforms. Kalshi subsequently added screening tools, while Polymarket expanded restrictions against market manipulation.
