Corporate and historical context

Okcoin traces its origins to the broader “OK” exchange ecosystem founded in the early 2010s; secondary sources commonly describe Okcoin as having been founded in 2013 by Mingxing (“Star”) Xu and later associated with the international OKX/OKEx brand family. (investopedia.com)

Rebranding to OKX (U.S. transition)

As of 2026, Okcoin’s own website states that “Okcoin is rebranding to OKX” as part of a brand consolidation effort. (okcoin.com)
Okcoin’s Help Center further states that, at 11:59 p.m. Central Time on May 15 (year not specified in the article text), trading services on Okcoin will be turned off and deposits will no longer be accepted, with customers instructed to withdraw assets by that deadline. The same article notes that wire deposits were no longer accepted as of January 2025. (support.okcoin.com)

Regulation and licensing (U.S.)

Okcoin’s licensing disclosures describe the U.S. platform as being provided by Okcoin USA Inc., identified as:

• a money services business (MSB) registered with FinCEN, and
• a licensed money transmitter, with NMLS ID #1767779, and a listed San Francisco address. (okcoin.com)

Okcoin’s licensing page also lists restricted U.S. states/territories (which may differ by document/version), indicating that availability depends on the user’s jurisdiction. (okcoin.com)

Relationship to OKX (as described by U.S. authorities)

A U.S. Department of Justice press release about OKX states that OKX has a U.S.-based affiliate exchange, OKCoin USA, Inc. (“OKCoin”), and distinguishes that affiliate from the non-U.S. entity discussed in the case. (justice.gov)
