Global business banking is fracturing along a fault line that most people in the industry sensed but could not quite name. On one side sits the domestic financial operating system, the world of corporate cards, expense management, bill pay, and treasury automation for companies whose money largely stays within the United States. On the other side sits something newer: borderless, stablecoin-native infrastructure designed for companies that move money across jurisdictions as a matter of routine. Three companies, at three very different stages of maturity, have staked out positions on this fault line. As we noted in our analysis of Wise’s move to Nasdaq and the structural shift toward global payment rails, the gravitational pull of US capital markets on companies building cross-border infrastructure has never been stronger.
Global Business Banking Splits Along a Domestic vs Cross-Border Fault Line
The split inside global business banking is not really about features. It is about underlying infrastructure choice. Ramp and Mercury have both built within the US banking system, working with FDIC-insured partner banks or seeking their own national charters. Limited has built outside that system from day one, with EU IBANs, PIX in Brazil, MX CLABE accounts for Mexico, stablecoin settlement, more than 300 payment rails, and self-custody wallets as core features rather than add-ons. The customer profile each platform serves follows from that infrastructure choice rather than determining it. Companies whose financial flows are primarily domestic gravitate to Ramp or Mercury. Companies operating across borders from day one gravitate to Limited. Global business banking is the umbrella category, but the implementations are increasingly incompatible.
Ramp’s $40 Billion Velocity Defines the Domestic Bet
Ramp is the most dramatic story of the three as a capital markets event. The New York-based spend management company, founded in 2019, is in advanced talks to raise $750 million at a pre-money valuation exceeding $40 billion, co-led by existing backers Iconiq Capital and Singapore’s sovereign wealth fund GIC, according to TechCrunch citing Wall Street Journal reporting. If completed, that would mark a 25% step-up from the $32 billion valuation Ramp achieved just six months ago. The trajectory is unusual. Ramp was valued at $13 billion in March 2025, $16 billion in June, $22.5 billion in July, and $32 billion in November. The proposed May 2026 round would be the fifth valuation step-up in fourteen months. You can follow the full timeline on our Ramp funding tracker.
Ramp crossed $1 billion in annualised revenue in late 2025 and reports being free cash flow positive. The company now serves more than 50,000 customers and enables more than $100 billion in annualised purchase volume. CEO Eric Glyman has been deliberate about repositioning the business as an AI operations layer for finance teams, with autonomous agents flagging out-of-policy purchases, detecting fraud in real time, sourcing vendors, reviewing contract terms, and sweeping idle cash into interest-bearing accounts. The platform now spans procurement, travel booking, bill payment, treasury, and accounting automation. Within global business banking, Ramp has become something closer to a financial operating system than the card product it started as. What Ramp is not, at least not yet, is a global business banking platform in any meaningful cross-border sense. Its infrastructure is built around the US banking system, and its customer base is predominantly US companies.
Mercury’s Charter Application Signals a Different Path
Mercury, founded in 2017 and launched in 2019, became the de facto banking stack for US startups, particularly those incorporated in Delaware. Inside the global business banking landscape, Mercury occupied the slot that traditional banks had failed to serve well. In March 2025, Mercury raised $300 million in a Sequoia-led Series C at a $3.5 billion valuation, doubling its previous valuation from a 2021 Series B. By the end of Q3 2025, Mercury had reached $650 million in annualised revenue, up 30% from $500 million at the end of 2024, and expects to have turned a profit for three consecutive years. The company serves 200,000 corporate customers and saw payment volume reach $156 billion in 2024.
Mercury’s path through global business banking has been more complicated than Ramp’s. The company was caught up in the fallout from the collapse of Synapse and its partner bank Evolve Bank and Trust in 2024 and early 2025, a saga that exposed the fragility of the Banking-as-a-Service model and triggered meaningful regulatory scrutiny of fintechs operating through bank partnerships. Mercury migrated its customers away from Evolve to Column N.A. and Choice Financial Group, a transition since completed. The company has also submitted its own application to the OCC for a national bank charter and applied for FDIC deposit insurance, a long-term bet on regulatory internalisation rather than continued dependence on partner bank infrastructure. The charter application is still under review. Mercury’s primary competitor Brex was acquired by Capital One earlier in 2026 for approximately $5.15 billion, concentrating the competitive landscape around Ramp and Mercury as the two dominant independent players in US startup and SMB banking.
Limited Builds for the Cross-Border Future
Limited is the company in this comparison that is least well known but arguably most interesting from a structural thesis perspective. It is building global business banking from scratch on cross-border infrastructure. Its bet is that the real opportunity inside global business banking is not in optimising how US companies manage domestic spend, but in building the financial infrastructure for companies that operate across borders from day one. The macro data behind that thesis is striking. SWIFT processes approximately $150 trillion in cross-border flows annually. The global cross-border payments market processed $190 trillion in transaction value in 2023 and is projected to reach $300 trillion by 2033. B2B payments covering supplier payments, cross-border invoicing, payroll, and wholesale trade account for $10 trillion of current annual flows and are projected to become the largest cross-border payment category by 2030.
The 733% B2B Stablecoin Surge in McKinsey Data
The specific data point that should recalibrate how the industry thinks about global business banking comes from the McKinsey and Artemis Analytics joint report covered by CoinDesk in early 2026. Of the roughly $35 trillion in total annualised stablecoin transaction volume, the report identified approximately $390 billion in genuine end-user stablecoin payment activity, stripping out trading noise, internal shuffles, and automated smart-contract cycling. Within that $390 billion, B2B payments dominate, accounting for about $226 billion, or roughly 60% of global stablecoin payment volume. B2B payments increased 733% year over year. We have published a detailed breakdown of what the McKinsey stablecoin data really means for finance teams and investors. The 733% B2B surge is not a consumer story delayed. It is a treasury story maturing. The enterprises building on stablecoin rails today are solving real operational problems, including cross-border friction, correspondent banking inefficiency, and working capital delays.
The monthly run-rate data is equally revealing. Monthly stablecoin payment volume stood at just $5 billion in January 2024. By early 2026, that figure had surpassed $30 billion, a sixfold increase in under two years, with the steepest acceleration arriving in the second half of 2025. Stablecoin market capitalisation has grown from under $30 billion in 2020 to over $300 billion today. US Treasury Secretary Scott Bessent has publicly projected that stablecoin supply could reach $3 trillion by 2030. Juniper Research, in a report published in late April 2026, found that the total value of cross-border B2B stablecoin transactions will reach $5 trillion by 2035, from $13.4 billion in 2026. That represents a 370-fold increase in under a decade, one of the most significant infrastructure transitions in the history of global business banking, and it is reshaping where global business banking innovation now centres.
The regulatory environment that any stablecoin-native global business banking provider must navigate has clarified substantially over the past eighteen months. The signing of the GENIUS Act in the summer of 2025 created the first comprehensive federal regulatory framework for payment stablecoins in the US, defining stablecoins issued by permitted issuers as payment instruments and mandating 100% reserve requirements. In Europe, MiCA moved from legislative framework into active supervisory enforcement, with a hard deadline of July 1, 2026 for all crypto-asset service providers to secure full authorisation or cease operations. Banks can now act as stablecoin custodians and issue their own stablecoins, and the structural integration of stablecoins into traditional financial infrastructure is now a compliance and execution challenge for global business banking providers rather than a speculative scenario.
Why All Three Bets Can Be Right at Once
The deeper strategic question these three companies illuminate is about market segmentation and the direction of global business banking’s evolution. The dominant narrative for the past five years has been about domestic efficiency. Ramp and Mercury have both built excellent businesses within that narrative. But the narrative is becoming insufficient as a complete account of what business banking needs to be. Supply chains run across borders. Remote teams span continents. Emerging-market customers and suppliers are increasingly central to revenue models that might have looked exclusively domestic a decade ago. Meanwhile, as our analysis of the UK political crisis and its impact on fintech shows, US business banking platforms are widening their lead at precisely the moment UK regulatory uncertainty is deepest.
The Ramp $40 billion valuation and the 733% B2B stablecoin growth are both real. They are measuring different parts of the same future. Ramp is playing a known game with extraordinary execution. Mercury is playing a similar but distinct game with deeper banking integration and its own charter application. Limited is playing a genuinely different game, where the total addressable market is measured in tens of trillions rather than billions, but where the execution risks are correspondingly higher and the regulatory complexity is multi-jurisdictional. What the data increasingly suggests is that all three bets may be correct simultaneously. Global business banking is not a single market converging on a single solution. It is splitting. The domestic US financial operating system that Ramp is winning and Mercury is competing in fiercely is one market. The global, borderless money movement layer that Limited is building for is another. The companies that will define the next decade of global business banking are probably not the ones that try to be everything to everyone. They are the ones that execute most precisely within their chosen world.
