Banks Block AI Agents; Revolut Launches UK Loans
Major US banks including JPMorgan, Bank of America, Citi, Wells Fargo, Morgan Stanley, and Schwab have restricted AI agents that log into customer accounts with shared passwords since mid-October, citing security concerns. Customers sharing credentials may lose fraud protection under Regulation E. Banks are developing their own agents and negotiating official access routes, potentially charging fees. Separately, Revolut has launched its first UK loans, offering £2,000 to £25,000 at rates between 6.9% and 29.3%, aiming to keep loan-to-deposit ratio around 6% and sell risk via securitisation. This move is part of a broader strategy to expand lending while managing valuation.
This article covers a critical development in the financial sector: banks blocking AI agents that access customer accounts, which affects the emerging field of agentic commerce and AI-driven financial services. The liability shift and the banks' move to build their own agents could reshape how AI agents interact with financial institutions, with significant implications for AdTech and MarTech companies that rely on such agents for payments and customer engagement. Revolut's entry into UK lending is also notable as a major fintech scaling its services.

Recent verified developments and strategic activity across this market segment.
Revolut valuation jumps 53% to $115B in share sale
Revolut has closed a secondary share sale valuing the fintech at $115 billion (€103 billion), a significant leap from $75 billion last year and $45 billion in 2024. Led by Glade Brook, Coatue, Durable Capital, T. Rowe Price, and Baillie Gifford, the deal allowed employees to sell shares at around $2,017 each without raising new capital. CEO Nik Storonsky emphasized employee ownership. The company serves over 80 million retail customers globally and plans to exceed 100 million. It has expanded internationally, launching local banks in Britain, Mexico, Australia, and New Zealand, and obtaining licenses in France, Colombia, Argentina, and preliminary U.S. approval. In Austria, IBANs will be issued from 2027. Revolut reported 2025 revenue of €5.3 billion (up 46%) and pretax profit of €2.0 billion (up 57%). An IPO, potentially at $200 billion, is delayed until after 2028.
Citi Downgrades Adobe Stock to Sell
Citi has downgraded Adobe Inc. from neutral to sell, citing the company's focus on long-term strategic changes over near-term growth. The investment bank lowered its price target to $207 from $250, implying roughly 16% downside from the prior close. Analyst Tyler Radke noted the incoming CEO Anil Chakravarthy will assume the role in December amid leadership vacancies, and expects strategic shifts in Adobe's Creative business that could pressure near-term growth. Additionally, rising competition from AI-integrated software and macroeconomic uncertainties pose challenges. Citi expects Adobe's annual recurring revenue (ARR) to grow only about 5% year-over-year through fiscal 2028, 200-300 basis points below consensus. The downgrade contradicts Wall Street consensus, as most analysts hold, but shares have already fallen ~30% year-to-date.
Marvell downgraded on $100B Lumentum acquisition concerns
Bank of America downgraded Marvell Technology to neutral from buy, citing concerns over its announced all-stock acquisition of photonics firm Lumentum Holdings. The deal, valued at over $100 billion, aims to position Marvell as a leader in AI connectivity but faces extended regulatory review, limited EPS accretion, and potential customer conflicts. Analyst Vivek Arya lowered the price target to $225 from $400, implying 31% upside. Shares closed down 13% on Monday, adding to a 12% decline over three months. The downgrade contrasts with consensus, as most of the 45 analysts covering the stock maintain buy ratings.
