Ownership, FDIC coverage, yield, cards, eligibility, and stablecoin support are compared for 2026. - Author: Milos Djukanovic - Tags: Fintech, neobanks Slash, Mercury, and Brex are three of the most visible business banking platforms in the US market, and they are frequently compared as though they are variations on the same product. In 2026 they are not. Each sits on a different corporate structure, holds deposits through different partner arrangements, sets different eligibility thresholds, and bundles a different mix of banking, cards, and treasury. This comparison sets out what each platform actually offers, where the structural differences lie, and which questions determine the fit, without ranking them against one another. > All three are compared on the same criteria here because they occupy the same category. None of them is presented as the better option, because that depends entirely on the business asking. ### Key Takeaways - All three partner with FDIC-member banks rather than holding deposits directly, though Mercury has received conditional approval to charter its own. - Ownership differs: Slash and Mercury are independent, while Brex became a Capital One subsidiary in April 2026. - Eligibility differs most sharply, with published revenue and funding thresholds varying by platform. - Published FDIC sweep ceilings and yield rates change frequently and should be verified directly. - Stablecoin support is uneven across the three, which matters for businesses settling on-chain. --- ## The Structural Picture Before comparing features, the corporate and banking structures are worth separating, because they determine what each platform can offer and how that may change. | | Slash | Mercury | Brex | | ------------------- | ----------------------------------------- | ---------------------------------------------- | --------------------------------------- | | Corporate status | Independent, $1.4B valuation (April 2026) | Independent, $5.2B valuation | Capital One subsidiary since April 2026 | | Is it a bank? | No, fintech with partner bank | No, but holds OCC conditional charter approval | No, fintech with partner banks | | Named partner banks | Column N.A. | Column N.A., Choice Financial | Column N.A., Emigrant Bank, Fifth Third | | Customers cited | 5,000 to 10,000 businesses | 300,000+ businesses | 25,000+ companies | Note that all three name Column N.A. among their partner banks, so a shared dependency exists across platforms that market themselves as alternatives to one another. The wider movement of fintechs toward their own charters is tracked in [**American Banker's running list of 2026 charter applications and approvals**](https://www.americanbanker.com/news/fintechs-asking-for-and-receiving-bank-charters-in-2026). [![Fintechs asking for, and receiving, bank charters in 2026](https://storage.ghost.io/c/73/6a/736af0e4-2274-4543-a329-2952b2b52abc/content/images/2026/08/Screenshot-2026-08-25-at-14.10.36.png)](https://www.americanbanker.com/news/fintechs-asking-for-and-receiving-bank-charters-in-2026) --- ## Slash Slash operates as a financial technology company with banking services provided by Column N.A., and it reached a $1.4 billion valuation in April 2026 through a $100 million Series C backed by Khosla Ventures and Ribbit Capital alongside earlier investors including NEA, Goodwater, and Menlo Ventures. Its published pricing runs a free tier at $0 per month and a Pro tier at $25 per month, with free domestic wires and ACH for Pro users. International wires are $25 on both plans and card purchases abroad carry a 1% foreign transaction fee with a $0.40 minimum. The Slash Platinum Card is a charge card issued by Column N.A. under Visa licence, advertising up to 2% cashback with unlimited virtual and physical card issuance and per-card spend controls. Published yield on idle cash has been cited in the 3.84% to 3.86% range, and FDIC coverage runs through Column's participation in IntraFi Cash Service, sweeping deposits across a network described as 800 or more banks. Slash also offers native stablecoin rails and Twin, an AI financial agent introduced alongside the Series C. --- ## Mercury Mercury operates as a financial technology company with banking through partner banks including Column N.A. and Choice Financial, and reports a $5.2 billion valuation with more than 300,000 business customers. Its structural position changed in April 2026, when it received conditional approval from the Office of the Comptroller of the Currency to establish Mercury Bank as a chartered national lender. If completed, that would reduce its dependence on the partner-bank arrangements it currently uses. Eligibility is comparatively open, with no minimum revenue, no personal guarantees, and no minimum employee count. FDIC coverage extends to approximately $5 million through its sweep network, and Mercury Treasury sweeps balances into US Treasury securities at published yields around 4%, subject to a $250,000 minimum across accounts. The Mercury IO Card is a charge card earning up to 1.5% cashback, with credit limits that adjust against the account cash balance. Mercury also publishes a developer API and runs Mercury Raise, an investor introduction programme. --- ## Brex Brex operates as a financial technology company with partner banks including Column N.A., Emigrant Bank, and Fifth Third Bank N.A., and became a subsidiary of Capital One when a $5.15 billion acquisition closed on 7 April 2026. Its published pricing runs three tiers: Essentials at $0 per user per month, Premium at $12 per user per month, and Enterprise at custom pricing. Eligibility is restricted to incorporated entities, with reported thresholds requiring roughly $400,000 in monthly revenue or venture backing. Brex Cash is structured as a brokerage cash management account rather than a checking account, with FDIC coverage to approximately $6 million through an insured cash sweep network. Published yield was 3.74% as of January 2026 on cash invested in a government money market fund, with no yield on uninvested balances. The Brex Card is a charge card with category-based rewards, and the platform bundles expense management, bill pay, travel booking, and multi-entity card issuance, with cards accepted across 210 or more countries and territories. --- ## Where the Differences Actually Sit Four dimensions separate these platforms in ways that affect real decisions, and each cuts differently depending on the business. ### **Eligibility** The thresholds differ substantially. Mercury publishes no revenue or funding minimum, Brex has reported requirements around monthly revenue or venture backing, and Slash markets account opening in under ten minutes for standard business entities. A business that does not meet one platform's criteria may qualify at another regardless of any other consideration. ### **Deposit protection** None of the three holds deposits directly today, so coverage depends on partner banks and sweep networks. Published ceilings differ, with Mercury citing around $5 million, Brex around $6 million, and Slash describing coverage extended through IntraFi across a large bank network. These figures are restated inconsistently across third-party sources and change over time, so verifying current terms directly with each provider is the only reliable approach. The distinction between a chartered bank and a fintech operating through partners is set out in the Congressional Research Service's [**analysis of bank charters**](https://www.congress.gov/crs-product/R47014). [![An Analysis of Bank Charters and Selected Policy Issues](https://storage.ghost.io/c/73/6a/736af0e4-2274-4543-a329-2952b2b52abc/content/images/2026/08/Screenshot-2026-08-25-at-14.30.36.png)](https://www.congress.gov/crs-product/R47014) ### **Yield structure** All three route idle cash toward government securities, with mechanics that differ. Mercury Treasury applies a $250,000 minimum, Brex distinguishes between invested and uninvested balances with no yield on the latter, and Slash publishes a rate on idle cash without a comparable stated minimum. Published rates sat in a similar band during 2026 and move with short-term interest rates. ### **Cards** All three issue charge cards rather than revolving credit. The reward structures differ in shape: Slash advertises a flat rate up to 2%, Mercury a flat rate up to 1.5%, and Brex a category-multiplier structure. Which produces more depends entirely on spending composition. --- ## The Stablecoin Dimension For businesses settling any portion of payments on-chain, the three platforms are not equivalent on this axis. Slash markets native stablecoin support as part of its platform. Brex has referenced cryptocurrency transfer functionality that reporting in 2026 described as still unavailable to most users. Mercury's public materials centre on conventional banking rails, treasury, and API access rather than on-chain settlement. This matters less than it might appear for many businesses, since converting stablecoins to dollars and moving them over ACH or wire can be handled separately from the banking platform, as our guide to [**off-ramping USDC to ACH or wire**](https://stablecoininsider.org/how-to-off-ramp-usdc-to-ach-or-wire/) sets out. Native support removes a step rather than enabling something otherwise impossible. [![How to Off-Ramp USDC to ACH or Wire (2026)](https://storage.ghost.io/c/73/6a/736af0e4-2274-4543-a329-2952b2b52abc/content/images/2026/08/Screenshot-2026-08-25-at-14.11.47.png)](https://stablecoininsider.org/how-to-off-ramp-usdc-to-ach-or-wire/) --- ## Questions That Determine the Fit Rather than a recommendation, five questions tend to resolve the choice on their own. **Do you meet the eligibility criteria?** This eliminates options before any feature comparison begins, and the thresholds differ enough that some businesses will only qualify at one. **How much idle cash sits in the account?** A $250,000 treasury minimum is irrelevant below that balance and central above it. **What does your card spend look like?** Concentrated category spend and diffuse spend favour different reward structures, and the answer is arithmetic rather than preference. **Do you need one platform or several?** Some businesses run banking on one platform and cards or spend management on another, which changes what any single platform needs to cover. **Does any of your revenue or payables settle on-chain?** If suppliers invoice in stablecoins, native rails reduce steps, though workflows for paying suppliers in USDC operate independently of the banking platform. --- ## What Applies to All Three Several characteristics are shared and worth stating plainly, since they are sometimes presented as differentiators. None of the three is currently a chartered bank, so deposits sit at partner institutions and protection depends on those relationships and their sweep arrangements. All three issue charge cards rather than revolving credit lines, so none replaces a traditional credit facility. All three operate in a category where pricing, yields, coverage ceilings, and eligibility criteria change frequently, and where several published figures already conflict across sources. For businesses moving any payables on-chain alongside these accounts, our guide to [**paying suppliers in USDC**](https://stablecoininsider.org/how-to-pay-suppliers-in-usdc/) covers the workflow. [![How to Pay Suppliers in USDC (2026)](https://storage.ghost.io/c/73/6a/736af0e4-2274-4543-a329-2952b2b52abc/content/images/2026/08/Screenshot-2026-08-25-at-14.13.39.png)](https://stablecoininsider.org/how-to-pay-suppliers-in-usdc/) --- ## Conclusion Slash, Mercury, and Brex occupy the same category and are built on different structures. Slash is independent and positions around cards, controls, and native stablecoin rails. Mercury is independent, holds conditional approval to become a chartered bank, and positions around banking primitives and treasury. Brex is a Capital One subsidiary positioning around a consolidated spend, travel, and expense platform. The differences that matter most are structural rather than promotional: who qualifies, how deposits are protected, whether idle cash clears a treasury minimum, and how card rewards are shaped. Each of those cuts differently depending on the business. No single platform is the right answer for every company, and published figures in this category move often enough that any comparison, including this one, should be checked against each provider's current terms before a decision is made. ***Read Next:*** - [**How to Off-Ramp USDC to ACH or Wire**](https://stablecoininsider.org/how-to-off-ramp-usdc-to-ach-or-wire/) - [**How to Pay Suppliers in USDC**](https://stablecoininsider.org/how-to-pay-suppliers-in-usdc/) - [**50 Fintech Statistics That Matter in 2026**](https://stablecoininsider.org/50-fintech-statistics-in-2026/) --- ## FAQs: ### 1\. Are Slash, Mercury, and Brex actual banks? None of the three is currently a chartered bank. All operate as financial technology companies with deposits held at FDIC-member partner banks, including Column N.A., which appears as a partner across all three. Mercury received conditional OCC approval in April 2026 to establish a chartered national bank, which would change its structure if completed. ### 2\. How much FDIC coverage does each provide? Coverage runs through partner banks and sweep networks rather than directly. Mercury cites approximately $5 million, Brex approximately $6 million through an insured cash sweep network, and Slash describes coverage extended through Column's participation in IntraFi across a large bank network. These figures are restated inconsistently across sources and change over time, so verify current terms with each provider. ### 3\. Which one is easiest to qualify for? Eligibility criteria differ substantially. Mercury publishes no minimum revenue, no personal guarantees, and no minimum employee count. Brex restricts access to incorporated entities with reported thresholds around monthly revenue or venture backing. Slash markets account opening in under ten minutes for standard business entities. ### 4\. Do any of them support stablecoins? Support is uneven. Slash markets native stablecoin rails as part of its platform. Brex has referenced cryptocurrency transfer functionality that reporting described in 2026 as still unavailable to most users. Mercury's public materials focus on conventional banking rails, treasury, and API access. ### 5\. Can I use more than one of them? Yes, and many businesses do. It is common to run banking on one platform and cards or spend management on another, since the three bundle banking, cards, and expense tooling in different proportions and none is required to be the sole provider. --- ***Disclaimer:*** This content is provided for informational and educational purposes only and does not constitute financial, investment, legal, or tax advice; no material herein should be interpreted as a recommendation, endorsement, or solicitation to buy or sell any financial instrument, and readers should conduct their own independent research or consult a qualified professional.
