Shayne Coplan is an American entrepreneur best known as the founder and CEO of Polymarket, a blockchain-based prediction market. In October 2025, at the age of 27, he was recognized by Bloomberg as the world's youngest self-made billionaire following a significant investment in Polymarket by Intercontinental Exchange (ICE), the parent company of the New York Stock Exchange.

After dropping out of college, Coplan experienced a period of financial difficulty. At the onset of the COVID-19 pandemic in 2020, at age 21, he described his situation as having "nothing to lose," stating he was running out of money two and a half years after leaving university with little to show for it. [6] He at one point sold personal belongings to cover the rent for his apartment in the Lower East Side of Manhattan. [2]
During 2019, he became disillusioned with what he termed "crypto grifts" and dedicated a year to studying the potential societal impact of prediction markets, drawing significant inspiration from the work of economist Robin Hanson. Coplan believed that the concept of aggregating information through markets was too valuable to be confined to academic papers and sought to create a practical application for it, noting that there were "a million reasons why it shouldn't work... but we had to try." [3] [6]
Shayne Coplan attended New York University (NYU) before making the decision to drop out to pursue ventures in the cryptocurrency industry. His formal education was cut short by his ambition to apply his ideas directly within the emerging digital asset space. [7] [2] [3]
Coplan founded Polymarket in June 2020, reportedly beginning development of the platform from a "makeshift bathroom office" during the COVID-19 pandemic. [2] [6] The platform allows users to wager cryptocurrency on the outcomes of real-world events, spanning politics, economic indicators, sports, and cultural milestones. As founder and CEO, Coplan retained a majority stake in the company. [3]
Under Coplan's leadership, Polymarket grew to host over 1.3 million unique users and handle more than $18.1 billion in trading volume. [5] The platform regularly facilitates over $1 billion a month in trading volume. [8] It experienced a significant "breakout moment" during the 2024 U.S. presidential election, where users wagered more than $3.5 billion on the potential outcomes in 2024 alone. [7] [1]
Polymarket attracted numerous high-profile investors, including Peter Thiel's Founders Fund, Ethereum co-founder Vitalik Buterin, Blockchain Capital, and 1789 Capital. [2] [7] In 2025, the company closed a $150 million funding round led by Founders Fund, which brought its valuation to $1.2 billion. [4] This was followed by a landmark announcement on October 7, 2025, that Intercontinental Exchange (ICE), the owner of the New York Stock Exchange, intended to invest up to $2 billion in Polymarket. The deal valued Polymarket at $9 billion and positioned ICE as a global distributor for Polymarket's event-driven data, with plans for future collaborations on financial tokenization projects. [5] [3]
In August 2025, Donald Trump Jr., a partner at the investment firm 1789 Capital, joined Polymarket as an adviser. [2]
Following the ICE investment, Coplan began hinting at the launch of a native token for the platform. On October 9, 2025, he posted on the social media platform X, listing "$POLY" alongside major cryptocurrencies like Bitcoin and Ethereum, suggesting an ambition for it to become a top-tier digital asset. [4] [5] Speculation had been building since September 2025, when Polymarket's parent company, Blockratize, filed documents with the U.S. Securities and Exchange Commission (SEC) that mentioned "other warrants," a strategy noted as being similar to that used by other crypto projects prior to their token launches. [4]
Coplan's and Polymarket's growth was marked by significant regulatory challenges in the United States, stemming from a business approach described as "move-fast, ask-permission-later." [2]
In 2022, Polymarket settled with the Commodity Futures Trading Commission (CFTC) for $1.4 million to resolve allegations of offering illegal trading contracts and operating as an unregistered exchange. As part of the settlement, in which the company did not admit or deny wrongdoing, Polymarket agreed to block users based in the United States from its platform. [1] [9]
Despite the ban, suspicions arose that the platform continued to serve American traders. In November 2024, one week after the U.S. presidential election where Polymarket's markets correctly predicted Donald Trump's victory, federal agents from the FBI raided Coplan's New York City apartment. [7] [9] Agents seized his cellphone and other electronic devices. Coplan, who was 26 at the time, was not arrested or charged. [9] Following the raid, he posted on X, "New phone, who dis?" Polymarket publicly characterized the raid as "obvious political retribution by the outgoing administration." [2] [9]
The raid was part of parallel investigations into Coplan and Polymarket by the U.S. Department of Justice (DOJ) and the CFTC. However, in early July 2025, Polymarket received formal notice that both the DOJ and the CFTC had officially dropped their respective investigations. This development, which occurred under the Trump Administration, cleared a major legal obstacle for the company and paved the way for its legal re-entry into the U.S. [1] [8] [10]
To secure a legal path for re-entry into the U.S. market, Polymarket acquired QCEX, a CFTC-licensed exchange and clearinghouse, in mid-2025. The acquisition, valued at $112 million, was finalized on September 4, 2025, providing the company with the necessary regulatory framework to operate legally in the United States. [3] [2]
