Intercontinental Exchange (ICE) invested $2 billion into Polymarket at a $9 billion post-money valuation, CEO Shayne Coplan announced on Oct. 7.
The deal represents the most significant single investment in prediction markets and positions the sector as crypto’s emerging battleground as institutional capital seeks on-chain infrastructure with real-world utility.
ICE is the owner of the New York Stock Exchange and the world’s largest exchange company.
Lynn Martin, president of NYSE, celebrated the partnership in a post before the opening bell. She said that the partnership will “help bring prediction markets into the financial mainstream.”
Beyond the investment
Coplan described the partnership as “a major step in bringing prediction markets into the financial mainstream” and “a monumental step forward for DeFi.”
The announcement also highlighted that ICE founder Jeff Sprecher plans to utilize NYSE infrastructure to advance the tokenization of assets. Additionally, ICE will distribute Polymarket data to thousands of financial institutions globally.
The investment follows two previously unannounced rounds. Coplan revealed that Founders Fund led a $150 million Series B earlier in 2025 at a $1.2 billion valuation, with participation from Ribbit, Valor, Point72 Ventures, and Coinbase.
Blockchain Capital also led a $55 million Series A in 2024 at a $350 million valuation.
What it means for prediction markets
Polymarket’s return to US markets gained regulatory clearance on Sept. 3 when the Commodity Futures Trading Commission (CFTC) issued a no-action letter to QCX LLC, enabling event contracts to operate under federal derivatives rules. QCX was acquired by Polymarket this year.
The approval marks a comeback for the platform, which ceased US operations in 2022 after settling unregistered derivatives charges for $1.4 million.
The regulatory green light arrives as prediction markets captured mainstream attention. September’s monthly volume more than doubled to $4.28 billion, up 126.3% from August’s $1.89 billion.
Kalshi seized market leadership with $2.74 billion in September volume, claiming roughly 64% share, while Polymarket posted 41.4% growth to $1.42 billion.
Haseeb Qureshi, partner at Dragonfly, called the move “a regime change” for prediction markets. He added:
“Polymarket + NYSE is a regime change. $2B investment means there’s a before and after now for prediction markets. We’re not in the kiddie pool anymore. Watch this space.”
Stani Kulechov, founder of Aave, praised Coplan’s focus and said “Polymarket is the future of news.”
Martin, from NYSE, added:
“Through the gold standard of financial infrastructure, we are redefining how modern markets operate.”
ICE’s entry validates prediction markets as institutional-grade infrastructure.
The backing of the world’s largest exchange operator and enthusiasm from established crypto figures suggest prediction markets have crossed from an experimental DeFi vertical to a category poised for mainstream adoption.
