Polymarket, a market platform, plans to raise $400 million in funding, valuing the company at around $15 billion.

According to two informed sources, the prediction market platform Polymarket is currently in talks with investors for a new round of financing, planning to raise $400 million, with a post-financing valuation of approximately $15 billion for the platform. The New York Stock Exchange's parent company, the Intercontinental Exchange, invested $600 million in the platform in the last round of financing last month, at which time the exchange only announced the investment news and did not disclose the valuation. Another source said that Polymarket plans to introduce other strategic investors beyond the Intercontinental Exchange in this round of financing, with the total size of the financing round expected to reach $1 billion. The current financing round has not yet closed, and there may still be adjustments to the terms.
