Polymarket, the largest decentralized prediction market platform by trading volume, has surpassed $1 billion in annualized revenue as of June 26, 2026, according to a source familiar with the matter cited by Reuters and reported separately by CNBC. The figure comes from a single anonymous source and has not been confirmed publicly by the company. The milestone arrives just six weeks after the platform opened its U.S. exchange to all users without a waitlist, following a CFTC Amended Order of Designation in November 2025. That regulatory step ended a roughly four-year period in which U.S. users were barred from the platform. Polymarket had also acquired a CFTC-regulated exchange in July 2025 as part of the compliance groundwork for its American re-entry, and it continues to pursue additional CFTC approvals.

The milestone is notable partly because of where the platform stood a year earlier. Throughout all of 2025, Polymarket generated zero revenue, operating entirely fee-free to grow liquidity and attract traders. Fee collection began in January 2026 on crypto markets, expanded to select sports markets in February, and reached a fuller schedule by March 30, 2026. That schedule charges taker-only fees up to 0.44%, while market makers pay nothing and receive a 25% rebate. Geopolitical and world events markets remain fee-free entirely.

The FIFA World Cup 2026 has been a significant accelerant. Trading volume across World Cup winner markets has crossed $3.1 billion in cumulative total. Daily volume in the soccer category jumped from roughly $53 million to $220 million during the tournament's opening stretch. At the same time, the U.S. exchange saw daily volume climb from approximately $50 million in mid-May to over $200 million by June 20. Analysts at Sacra estimated Polymarket's annualized revenue at around $375 million as recently as May 2026, which means the platform more than doubled that figure in roughly a month. The acceleration is consistent with the U.S. volume surge and World Cup activity.

The platform runs on the Polygon blockchain and settles trades in pUSD, a stablecoin that replaced the platform's older bridged USDC.e token and is backed one-to-one by native USDC under a partnership with Circle announced on February 5, 2026. That infrastructure migration formed part of the compliance groundwork for the U.S. re-launch. Polygon keeps transaction costs between $0.001 and $0.01, compared with $5 to $50 per equivalent transaction on Ethereum's main network. That cost advantage matters beyond the United States. Monthly unique wallets grew nearly threefold year over year, reaching roughly 840,000 by February 2026, according to blockchain analytics firm TRM Labs. The growth is driven largely by new participants entering the platform rather than existing users trading more, a sign of genuine geographic expansion. Even so, a lack of local fiat on-ramps remains a practical friction point across many of these emerging markets, limiting accessibility despite the platform's low transaction costs.

That expansion is uneven by region and constrained by varying regulatory postures. Following earlier blocks by Taiwan and France, Singapore's Gambling Regulatory Authority declared Polymarket an illegal gambling platform on January 12, 2025. Users there face fines up to SGD 10,000 and up to six months imprisonment. India has not issued a block, and a substantial user base exists there, but the regulatory status of prediction markets sits in an unresolved gap between crypto asset rules and online gaming law. In Sub-Saharan Africa, Kenya and Nigeria both allow access without platform-level restrictions. Nigeria's updated Investments and Securities Act of 2025 formally recognized digital assets under the Securities and Exchange Commission of Nigeria (SEC Nigeria), and the Central Bank of Nigeria (CBN) has eased restrictions on licensed digital asset providers, though no rules specific to event contracts exist yet. A legal analysis published by ENS Africa authors Altair Richards et al. in May 2026 described South Africa's situation as sitting at "one of the more interesting fault lines" in the country's evolving crypto framework, implicating the Financial Sector Conduct Authority under the Financial Advisory and Intermediary Services Act, Capital Flow Management Regulations, and the Financial Markets Act simultaneously, with no clear resolution from any of them. More broadly, none of the African or South Asian markets covered here have issued any regulatory guidance specifically addressing prediction markets as a distinct product class.

Intercontinental Exchange, the company that owns the New York Stock Exchange, has invested in Polymarket across two tranches: a Series D in October 2025 and a follow-on in March 2026, with its total carrying value in the platform reaching approximately $2 billion. ICE also distributes Polymarket's institutional data product, Polymarket Signals and Sentiment, through its own infrastructure. The platform is now in discussions to raise $400 million in new capital at a valuation near $15 billion, up from $9 billion last year. Bernstein analysts have projected that prediction market trading volumes across the industry could reach $1 trillion by 2030. Combined volumes for Polymarket and U.S. rival Kalshi have already reached $60 billion year-to-date in 2026, with the full industry projected to reach around $240 billion for the year.

The regulatory picture is still taking shape. Polymarket is seeking CFTC permission to reopen its main global exchange to U.S. traders, a step that would let it compete more directly with Kalshi, which as of late April 2026 held a $22 billion valuation and $1.5 billion in annualized revenue. The competitive field is expanding beyond those two players: Robinhood is building event-contract capabilities in partnership with trading firm Susquehanna International Group, and DraftKings entered the space by acquiring Railbird, a CFTC-licensed prediction market platform. In March, Polymarket and Kalshi jointly published their Enhanced Market Integrity Rules on March 23, 2026, establishing shared insider trading restrictions for both platforms. The U.S. House Committee on Oversight sent a letter to Polymarket CEO Shayne Coplan on May 22 signaling growing legislative interest in the sector. Coplan, 27, founded the platform while in college and left before graduating to run it full-time. A native POLY token had been announced for launch in early 2026, though its current status has not been publicly confirmed. An IPO is reportedly under discussion as well. For now, the platform's growth is outpacing the regulatory frameworks in most of the markets where it operates.
