Adventure One QSS Inc.

History

Polymarket was founded by Shayne Coplan in June 2020 in New York City as a U.S.-based prediction market startup. Soon after launch, the platform faced regulatory scrutiny for offering binary options without a license in jurisdictions such as Ontario, Canada. To continue serving international users, the operational duties were transferred to a newly created Panama-based entity, Adventure One QSS Inc., incorporated in Panama several months before becoming the platform’s operator. Between June 2020 and May 2023, first Blockratize Inc. and then Adventure One QSS Inc. operated the Polymarket platform. During this period, the Ontario Securities Commission (OSC) found that both entities violated Ontario securities law by offering binary options to residents without registration or prospectus. The OSC reached a settlement with the respondents in early 2025, with the Canadian regulator imposing penalties and requiring the platform to cease operations in the province. In July 2025, the Australian Communications and Media Authority (ACMA) issued a formal warning to Adventure One QSS Inc. for contravening the Interactive Gambling Act 2001 by providing a prohibited and unlicensed interactive gambling service (the Polymarket platform) to Australian customers. In 2025 and 2026, Adventure One QSS Inc. (via Polymarket) raised substantial venture capital. A $200 million round led by Founders Fund was reported to be on the verge of closing in June 2025, and a $1 billion funding round led by Coatue Management was completed in March 2026. In August 2025, Donald Trump Jr. joined the company in an advisory capacity.
