Former U.S.-based online trading services provider specializing in foreign exchange, CFDs and related market-access services.
Last updated August 26, 2026
Overview
GAIN Capital was a United States-based online trading services provider founded in 1999 in Bedminster, New Jersey. The company emerged during the early development of electronically delivered retail foreign-exchange trading and built a business serving both individual and institutional market participants. Its services gave customers access to foreign exchange, contracts for difference, margin-based speculation and exchange-traded products through electronic execution platforms. The company operated across several parts of the trading-services value chain. Its retail brands included Forex.com, which became its largest consumer-facing foreign-exchange business, and City Index, a British-origin platform acquired in 2014 that strengthened GAIN Capital's CFD, spread-betting and international operations. The group also operated GTX, an electronic communications network and multi-dealer foreign-exchange venue aimed at hedge funds and institutional clients. Other businesses included SALT Invest, an advisory CFD operation, and Daniels Trading, a futures brokerage and trading-services provider. GAIN Capital's technology offering centered on its proprietary FOREXTrader PRO platform, later renamed StoneX Pro after the acquisition by StoneX Group, together with MetaTrader 4. The company also provided market-access, execution and white-label services to other online trading businesses. Its customer base extended across more than 140 countries, and the business generated more than half of its revenue outside the United States according to the referenced company description. Operations and affiliates had offices in the United States, the United Kingdom, Poland, Australia, Hong Kong, Japan and Singapore. GAIN Capital became a public company in 2010, although its initial offering was reduced shortly before completion because the intended price level was not achieved. Its subsequent expansion was driven in part by acquisitions. In October 2014, it purchased UK-based rival City Index for approximately $118 million, adding scale in CFDs and expanding the group's position in the United Kingdom and other international markets. In February 2017, it agreed to purchase the U.S. customer accounts of FXCM after U.S. regulators barred FXCM from conducting business in the country. The transaction used a contingent payment structure based on subsequent account activity. The company also faced regulatory scrutiny. In 2008, China's banking regulator determined that GAIN Capital had breached rules concerning the direct online solicitation of Chinese residents for retail foreign-exchange services without the required permission. GAIN Capital temporarily stopped accepting Chinese clients between 2008 and 2010. In 2010, the National Futures Association fined the company over alleged margin, liquidation and price-slippage practices that were considered detrimental to customers. GAIN Capital agreed to pay a fine and reimburse affected customers for negative slippage during the specified review period. In February 2020, StoneX Group, then known as INTL FCStone, announced an all-cash agreement to acquire GAIN Capital Holdings. The transaction was approved by the boards of both companies and valued at approximately $236 million in equity value. Following completion, GAIN Capital ceased to operate as an independent listed company, while important brands and platforms, including Forex.com, City Index and the proprietary trading technology later known as StoneX Pro, continued within StoneX's broader financial-services structure.
History
GAIN Capital was established in 1999 in Bedminster, New Jersey, during the early expansion of internet-based foreign-exchange trading. Rather than operating as a traditional bank, it developed electronic systems that allowed retail and institutional customers to obtain market access and execute leveraged trades in global currency markets. The company's core activity became margin foreign-exchange trading, in which customers used collateral to take positions whose notional value exceeded the funds deposited in their accounts. Over time, GAIN Capital broadened its business beyond retail forex. Its consumer trading operations were represented primarily by Forex.com, while its institutional division included GTX, a multi-dealer foreign-exchange platform and electronic communications network for professional market participants. The company also operated or owned businesses associated with CFD advice and futures trading, including SALT Invest and Daniels Trading. Its technology stack included the proprietary FOREXTrader PRO platform and MetaTrader 4. The proprietary platform was later renamed StoneX Pro after the acquisition of GAIN Capital by StoneX Group. International expansion was central to the company's development. Although headquartered in the United States, GAIN Capital served customers in more than 140 countries and generated more than half of its revenue outside the United States according to the referenced account. Affiliates and offices were located in several major financial and technology centers, including New York and New Jersey, London, Cracow, Sydney, Hong Kong, Tokyo and Singapore. The company also supplied white-label trading infrastructure to other online foreign-exchange businesses. GAIN Capital's growth was accompanied by regulatory challenges. In 2008, China's financial regulator objected to the company's direct internet solicitation of Chinese residents for retail forex services without a required permit. The company temporarily stopped accepting Chinese clients during the period from 2008 to 2010. In October 2010, the National Futures Association imposed a $459,000 fine after alleging that GAIN Capital's margin, liquidation and price-slippage practices benefited the firm at customers' expense. GAIN Capital agreed to reimburse customers for negative slippage on affected trades during the review period. The company entered public markets in 2010. Its initial New York Stock Exchange offering was reduced shortly before launch because the proposed price was not achieved, but the listing nevertheless provided a public-company structure for subsequent expansion. In October 2014, GAIN Capital purchased City Index, a UK-based competitor, for approximately $118 million. The deal added a large CFD and spread-betting operation and increased GAIN Capital's reach in Britain and other non-U.S. markets. In 2017, GAIN Capital expanded its U.S. retail customer base by agreeing to acquire FXCM's U.S. accounts after regulatory action prevented FXCM from continuing American operations. The purchase price varied according to account activity, with different payments applying to accounts that traded within specified periods. This transaction reinforced GAIN Capital's role as one of the established U.S. online forex providers. GAIN Capital's independent corporate existence ended in 2020. StoneX Group, then operating under the INTL FCStone name, agreed to acquire the company in an all-cash transaction valued at about $236 million in equity value. After the acquisition, GAIN Capital was no longer an independent listed company, while its principal brands, customer operations and trading technology became part of StoneX's wider financial-services business.
