Mercury, the fintech company providing banking services to startups, has raised $200 million in a new funding round, pushing its valuation to $5.2 billion. The round completed on May 20, 2026, marking a 49% increase from its $3.5 billion valuation 14 months earlier.
More significant than the funding, however, was the preliminary approval of a national bank charter from the Office of the Comptroller of the Currency (OCC) in April. This is a watershed moment for Mercury: previously it operated as a middleman connecting to partner banks; now it is on track to become a full-fledged federal bank.
How the $200 Million Is Allocated
The round features familiar names:
- Lead investor: TCV (Technology Crossover Ventures)
- Participants: Sequoia, Andreessen Horowitz, Coatue
- Total: $200 million
- Valuation: $5.2 billion (post-money)
Mercury has raised $700 million cumulatively since 2017, with this single round accounting for 28% of that total. The valuation trajectory — $3.5 billion (March 2025) to $5.2 billion (May 2026) — represents a 49% increase in 14 months. For a corporate banking company, this jump is not excessive given market sentiment in May 2026, but it is certainly not cheap.
Can the Financials Support This Valuation?
Yes, they can.
- Annualized revenue: $650 million (Q3 2025)
- Profitable for four consecutive years
- Over 300,000 business customers
- One in three early-stage U.S. startups is a Mercury customer
These metrics show that Mercury's story is not about future growth promises but about an already profitable banking business poised to ride the AI startup wave. Compared to competitors like Brex and Ramp, which are still burning through cash, Mercury's combination of profitability and a customer base entrenched in the AI era makes TCV's late-stage investment logical.
The Bank Charter Is the Real Game Changer
Many overlooked the OCC's preliminary approval in April, which fundamentally changes Mercury's business model.
Before the charter:
- No own bank license
- Customer deposits held at partner banks like Choice Bank and Evolve Bank
- Revenue primarily from interest sharing and wire transfer fees
After the charter:
- Can issue loans directly
- Access mainstream payment networks like Zelle
- Reduced reliance on partner banks, significantly boosting gross margins
CEO Immad Akhund has stated that Mercury will not sell to a bank and aims for an IPO. In plain terms, Mercury is repositioning itself as an independent federal bank for tech companies, rather than a fintech middle layer.
CEO Links Growth to AI Startup Boom
Akhund made a notable remark:
"AI is collapsing the friction between an idea and a company faster than anything I have seen in my career."
In other words, AI has compressed the time from having an idea to forming a company to a pace he has never witnessed. Starting a company, registering a legal entity, building a demo, and launching an MVP now takes weeks or days instead of months. Each new company needs a business account, and early founders are unlikely to spend two weeks applying for a Chase account. That is Mercury's entry point.
Akhund also noted that mainstream bank infrastructure has barely changed since 2006. This is a sharp critique: traditional banks have not only failed to catch up with fintech but have not even updated their APIs. Mercury itself has launched an AI agent for account management, allowing payments, invoicing, and reconciliation via AI interfaces. Akhund revealed that a more comprehensive conversational banking assistant will be released by year-end, enabling customers to approve payments using natural language.
What to Watch Next
Whether the bank charter progresses from preliminary to final approval is the key hurdle for Mercury to move from a $7 billion valuation to $10 billion.
Short-term metrics to monitor:
- How quickly ARR grows from $650 million to the next milestone
- The timeline for OCC final approval — typically 6 to 18 months from preliminary approval
- Adoption of the conversational banking assistant after its year-end launch
Mercury's combination of profitability, real charter prospects, and a customer base tied to the AI startup wave makes it a rarity in the current primary market. Whether its next valuation can double will depend on OCC progress after June.
