Company News
Citigroup is expanding its digital asset infrastructure with the launch of Custody+, a new platform combining faster settlement, real-time asset servicing, foreign exchange, liquidity management and planned digital asset custody. The platform complements Citi Token Services, which enables round-the-clock transfers of tokenised deposits. Citigroup's Services segment showed strong momentum in the first half of 2026, with revenues up 17% year-on-year. Assets under custody rose 22% to approximately $35 trillion, whilst Securities Services deposits increased 15% to $165 billion. The bank invests over $2 billion annually in its Services platform. An initial Bitcoin offering is expected later in 2026. Morgan Stanley has also entered the space with the launch of Ethereum and Solana trusts.
Bitcoin tested $65,000 on Tuesday as two Wall Street institutions deepened their cryptocurrency commitments. BlackRock reiterated its recommendation for a 1–2% portfolio allocation to Bitcoin, arguing the recent selloff stemmed from forced selling rather than weakened fundamentals. The asset manager's iShares Bitcoin Trust held over $47 billion by March 2026. Meanwhile, Citi unveiled Custody+, a new platform that will offer Bitcoin custody alongside traditional assets later this year. The bank is investing over $2 billion annually in platform infrastructure covering more than 100 markets. Amit Agarwal, head of custody at Citi Investor Services, said the platform matches clients' strategy speeds. Bitcoin traded near $64,708 at press time, roughly 50% below its October 2025 peak.
Hopscotch Primary Care, a technology-enabled primary care provider serving rural communities, has raised $53 million in Series D funding. Lead investors include 8VC and Townhall Ventures, with participation from existing backers and new investors including the Autism Impact Fund, John Doerr, Dr Richard Merkin, and the Leon Levine Foundation. Founded in 2021, Hopscotch serves over 15,000 patients across 12 locations in the southeastern United States, with its largest concentration in rural Western North Carolina. The company will use the funding to expand access across the region, enter new rural markets, and scale its technology operations. Hopscotch reports a Net Promoter Score of 89, patient retention above 90%, and profitable operations in Western North Carolina. The company offers same-day visits and 24/7 access to care teams.
Citi Investor Services has launched Custody+, a suite of near- and real-time custody solutions designed for institutional investors navigating compressed settlement cycles and continuous markets. The announcement follows completion of the US rollout of Citi's patented Single Event Processing technology. Custody+ offers a modular ecosystem adaptable to client workflows at scale. Key capabilities include real-time asset servicing, which has reduced processing times for voluntary corporate actions by up to 92%, with 96% of US voluntary events now processed under two hours. The suite also features instant settlements, on-demand foreign exchange, and real-time cash and liquidity solutions. Citi expects to launch digital asset custody later this year, starting with Bitcoin. The bank invests over $2 billion annually in its platform strategy, supporting clients in over 100 markets worldwide.
Citigroup has appointed Adam Clark as head of wealth planning, according to an internal memo. Clark will join from J.P. Morgan, where he served as global head of Trusts and Estates, overseeing 500 staff across 40 offices worldwide. He replaces Mike Troth, who held the position on an interim basis. Clark is set to begin in November after completing garden leave and will be based in New York. At J.P. Morgan, Clark managed the bank's global trusts and estates operations and worked with ultra-high-net-worth clients on complex financial matters. Previously, he spent seven years at Goldman Sachs in roles including president of the Goldman Sachs Trust Company. Clark will report to Keith Glenfield, Citi Wealth's investment solutions head.
