The company's lineage begins in 1924, when Saul Stone founded a commodity brokerage in Chicago that became Saul Stone and Company. For decades it served agricultural hedgers and traders in the Midwest's grain markets.

The modern business was built through serial acquisition by Saul Stone's successors, eventually operating as FCStone Group. A defining period began in the 2000s under Sean O'Connor, who expanded the firm from a niche commodities broker into a diversified financial group through more than 30 acquisitions: futures clearing, securities brokerage, global payments, metals trading and market intelligence.

A 2009 merger combined FCStone with International Assets Holding Corporation, and the renamed INTL FCStone continued its buying streak through the 2010s, adding the GPM metals business, Allen & Company-era assets and FX trading operations.

The largest single move came in 2020, when the company acquired GAIN Capital Holdings, owner of retail forex brands FOREX.com and City Index, for approximately $236 million, completing in July 2020. That same month the parent renamed itself StoneX Group Inc., unifying decades of acquired businesses under one identity.

The 2020s added record results and bigger deals. The 2025 completion of the R.J. O'Brien acquisition, the Chicago futures brokerage, at a reported value exceeding $900 million, made StoneX one of the largest futures commission merchants in the world. FY2025 closed with operating revenues of $4.13 billion, total revenues of $132.4 billion including physical commodities flows, and record net income of $305.9 million.

The company's structure was built deal by deal. The 2009 combination of FCStone Group with International Assets Holding created a publicly traded platform with clearing capabilities; the renamed INTL FCStone then spent the 2010s acquiring its way into adjacent businesses: metals trading through the GPM purchase, global payments, foreign exchange, securities brokerage and market intelligence.

Sean O'Connor, who led the company from 2002 through its transformation, made acquisition integration a core competency: StoneX typically buys operating businesses at disciplined multiples and plugs them into its clearing infrastructure and client relationships, a model that compounded book value for two decades and produced a diversification that pure-play rivals lack.

The July 2020 GAIN Capital acquisition, approximately 236 million dollars, added the retail trading brands FOREX.com and City Index, and the parent simultaneously renamed itself StoneX Group, unifying the accumulated portfolio under one identity for the first time.

The largest deal of its recent history closed in 2025: the acquisition of R.J. O'Brien, the venerable Chicago futures brokerage founded in 1914, at a reported value exceeding 900 million dollars. The combination created one of the largest futures commission merchants in the world by client equity, consolidating two independent clearing franchises as banks continued retreating from the business.

StoneX's regulatory record carries the ordinary incidents of a large FCM: periodic CFTC and exchange actions on supervision and reporting, settled without material impact. Its retail forex subsidiary GAIN Capital paid a $500,000 CFTC settlement in 2019 over execution supervision.

The larger governance story is compensation and founder-era deals: the company's growth-by-acquisition model has produced occasional shareholder criticism of integration costs, though record FY2025 results muted the debate.
