ICE adds $600m to Polymarket investment despite US regulatory oversight
Intercontinental Exchange (ICE), parent of the New York Stock Exchange (NYSE), announced Friday that it has completed a $600 million direct cash investment.
The company said it expects to buy up to $40 million in Polymarket securities from existing owners, adding to an investment commitment it previously made in October 2025.
In that earlier deal, ICE said it would invest up to $2 billion in Polymarket, one of the largest institutional moves into the prediction market sector. That arrangement follows recent transaction developments, although terms of the new investment, including valuation, were not disclosed.
The deal shows ICE's desire to expand its exposure to valuation markets, even as the sector faces US regulatory scrutiny.
Polymarket's scale underscores the role of infrastructure, Polygon Labs said.
Aishwari Gupta, head of global business at Polygon Labs, said ICE's latest investment reflects institutional focus on onchain marketplaces.
Gupta told Cointelegraph that Polymarket's development on Polygon demonstrates how blockchain infrastructure can be used to support high-frequency and real-time market activity.

“Intercontinental Exchange's investment in Polymarket highlights the growing institutional interest in onchain market platforms,” Gupta said.
Polymarket's growth on Polygon demonstrates how blockchain infrastructure can support real-time market activity at scale, he said.
Regulators in 11 states have taken action against prediction markets.
The news comes as forecast markets face increasing regulatory pressure across the US.
At least 11 states are taking legal action against prediction marketplaces such as Polymarket and Kalshi.
Nevada has issued a temporary ban on Polymarket competitor Kalshi, while Arizona has filed criminal charges against the platform for operating illegal gambling. Several other states have issued cease-and-desist orders or are considering new legislation.
Polymarket recently updated its rules to expressly prohibit trading on confidential information as lawmakers and critics worry that prediction markets could be particularly vulnerable to activities around politics, sports and geopolitics.
