Polymarket is a prediction market: users buy and sell shares in yes/no outcomes for elections, sports, economic data, weather, awards, legislation and world events, and the price of a share becomes a real-time probability estimate. The company was founded in June 2020 by Shayne Coplan, who was 21 at the time and still runs it as CEO and majority owner. It is headquartered in Manhattan, New York, with a legal domicile in Panama, and its international exchange settles in USDC on the Polygon blockchain through a hybrid order book.
The company spent its first years as a crypto-native DeFi experiment. It raised a $4M seed led by Polychain Capital in October 2020, a $70M Series A/B in May 2024 backed by Founders Fund, General Catalyst and Vitalik Buterin, and two undisclosed rounds — $55M in 2024 led by Blockchain Capital at a $350M valuation and $150M in 2025 led by Founders Fund at a $1.2B valuation — that Coplan disclosed only in October 2025. The 2024 U.S. presidential election made it mainstream: more than $3.3B was wagered on that race on the platform, and its odds were quoted alongside polls by national media.
Regulation shaped the company's second act. After a January 2022 CFTC settlement forced it to wind down U.S. operations and pay a $1.4M penalty, Polymarket blocked American users and grew internationally, handling more than $6B in trades in the first half of 2025 alone. In July 2025 the CFTC and DOJ closed their investigations without charges, and Polymarket acquired QCX LLC, a licensed U.S. exchange, for $112M. It launched Polymarket US as a CFTC-regulated designated contract market in December 2025, dropped the waitlist in May 2026, and now runs a separate U.S. order book alongside the international one. ICE's up-to-$2B investment, announced October 2025 and completed with a further $600M in March 2026, made the NYSE parent both a major shareholder and a global distributor of Polymarket's event data.
The business model changed in 2026. Polymarket historically charged no trading fees, earning mainly on collateral float, spreads and data; in April 2026 it expanded taker fees across nearly all markets (0.04-0.07 × p(1-p), peaking at $1.75 per 100 crypto shares and $1.25 for sports at 50¢, with 15-25% maker rebates and geopolitics fee-free). Combined with the World Cup and the open U.S. exchange, that pushed reported daily fees past $1M and, per the company, annualized revenue above $1B by late June. Growth is now strategic as well as consumer: Polymarket partnered with Nasdaq Private Markets on prediction markets for private companies in May 2026 and acquired DeFi infrastructure startup Brahma in March 2026 to smooth onboarding and settlement. The reputational file is not clean — insider-trading episodes, influence-campaign allegations, paid-influencer coverage and the ethics of war and disaster markets are recurring criticisms — and the regulatory file is not settled, with the CFTC suing nine states to defend its exclusive jurisdiction while federal appeals courts have begun letting states regulate event contracts as gambling.
Polymarket is the category-defining prediction market, and 2026 is the year it stopped being a crypto curiosity and became a financial exchange with a real business. In one year it cleared its regulatory path back into the United States, launched a CFTC-regulated exchange, lifted the U.S. waitlist, expanded trading fees far enough that the company told CNBC its annualized revenue passed $1 billion, and was reported raising $1B at a $21B valuation led by 1789 Capital — up 40% from the $15B round it closed quietly in April with D.E. Shaw and G Squared. NYSE parent Intercontinental Exchange has committed up to $2 billion, giving the world's most-watched crypto-native venue the balance sheet and data distribution of a legacy exchange operator.
The arc is unusual. Founded in June 2020 by Shayne Coplan, Polymarket was fined $1.4M by the CFTC in 2022 and blocked from serving U.S. users, so it built abroad — and became famous doing it, with the 2024 presidential race drawing more than $3.3B. Then the calculus flipped: a second Trump administration eased the regulatory environment, the CFTC and DOJ dropped their probes in July 2025, Coplan bought a licensed exchange (QCX) for $112M, and Donald Trump Jr. joined as an advisor while his firm 1789 Capital invested. ICE followed with up to $2B at an $8B pre-money valuation in October 2025. By May 2026 the U.S. exchange was open to any American with the mobile app, and daily notional volume had climbed past $100M domestically and $150M internationally.
The open questions are as large as the opportunity. Kalshi, its most direct regulated rival, raised at $22B in May 2026 and is reported to be seeking $40B, while federal appeals courts have begun siding with states that want to treat event contracts as gambling — a patchwork that could shrink the national market Polymarket's valuation assumes. Prediction markets remain plagued by insider-trading optics, market-manipulation debates and the reputational baggage of betting on war and disaster, and Polymarket's own fee shift in 2026 puts it in the awkward position of monetizing the liquidity that made it dominant. The bear case is that the category's growth is real but its winner is still undecided and its regulatory footing still fragile; the bull case is that once an exchange becomes the default place to price the future, everything else is distribution. Polymarket is the purest bet on that thesis.
