Polymarket and the New York Stock Exchange: A rapprochement around tokenized shares

From prediction markets to stocks on blockchain. Shayne Coplan, founder and CEO of Polymarket, declared on October 7 at TOKEN2049 in Singapore that Intercontinental Exchange (ICE), parent company of the New York Stock Exchange, is among the main shareholders of its platform. According to his remarks reported by PANews, ICE is also working with regulators on issues related to on-chain actions.

These declarations extend a merger initiated in October 2025. The initial agreement already combined capital investment, data distribution and cooperation on future tokenization initiatives.

ICE, a major shareholder of Polymarket

The presence of ICE in the capital is not new. On October 7, 2025, the group announced a strategic investment of up to $2 billion, based on a valuation of Polymarket of around $8 billion before investment. The market operator also wanted to become a global distributor of the platform's data to financial institutions.

On March 27, 2026, ICE announced that it had made a first direct investment of $1 billion in October, then a new contribution of $600 million. The group also planned to purchase up to $40 million of securities from existing shareholders. These operations were to complement its obligations under the original agreement.

We must therefore distinguish the ceiling of 2 billion announced at the start from the 1.6 billion dollars of direct investments confirmed in March. Purchases of existing securities constitute a separate transaction: the money goes to the sellers rather than to Polymarket.

Mr. Coplan's statements underline the strategic weight of this shareholder. However, they do not give a new percentage of participation or indication of a change of control.

Prediction data and tokenization: Two linked projects

The cooperation has already produced a concrete service. In February 2026, ICE launched Polymarket Signals and Sentiment, a tool that structures prediction market data for professional investors.

These data represent the implicit probabilities assigned by participants to different events. ICE offers them as complementary signals to traditional financial data, with flows close to real time and histories intended in particular for quantitative analyses. They reflect market expectations, without guaranteeing future results (of course!).

Tokenization also featured in the October 2025 agreement. It consists of representing financial assets or rights by tokens on a blockchain. Its deployment on the equity markets requires in particular defining the rights of holders, the storage arrangements and the trading rules.

According to reported comments from Shayne Coplan, ICE is continuing this work with regulators. However, no specific platform, launch date or authorization obtained is announced in this statement.
