The numbers that changed the conversation

Let's start with what actually happened. In the span of two years, stablecoins went from a $130 billion market to over $312 billion. The total supply of USDT alone sits at $187 billion. USDC grew 73% in a single year. The combined transaction volume of just these two assets exceeded $31.6 trillion in 2025.

But the number that should stop you is this one: stablecoins now account for 30% of all on-chain crypto transaction volume — and that share is growing every quarter.

This isn't speculative trading volume. Increasingly, this is payroll. It's remittances. It's B2B settlement. It's cross-border payments that used to take three days and cost $45, now settling in seconds for pennies.

The GENIUS Act, signed into law in July 2025, created the first federal framework for payment stablecoins in the United States. Europe's MiCA regulation did the same across the EU. For the first time, the world's two largest economies gave stablecoins a legal home. And the market responded immediately — 54% of financial institutions and corporates that weren't yet using stablecoins said they planned to adopt within six to twelve months.

The infrastructure era had officially begun.

Why this matters if you're building a banking product

Here's the part most founders miss: stablecoins don't just change how money moves. They change what a bank can be.

Traditional banking infrastructure is built on a stack of intermediaries — correspondent banks, clearing houses, card networks, payment processors. Each one adds latency, cost, and complexity. Building a banking product on top of this stack used to mean months of integration, millions in licensing, and a permanent dependency on systems designed in the 1970s.

Stablecoin rails collapse that entire stack into a single layer. A dollar-denominated stablecoin can move from one wallet to another, across borders, in under a second, for a fraction of a cent. No correspondent bank. No three-day settlement window. No SWIFT fees.

For anyone building a neobank, a payment app, a remittance product, or even a corporate treasury tool — this changes the economics completely. Your cost per transaction drops. Your settlement time drops. Your geographic reach expands instantly. And your users get an experience that feels like the future, because it is.

The 39% of U.S. merchants that already accept crypto? They're not doing it because they love blockchain. They're doing it because 88% of them are getting asked by customers, and 79% believe it helps attract new ones. The demand is already there. The infrastructure to serve it is what's been missing.

The card connection

One of the clearest signals that stablecoins have become infrastructure — not just an asset class — is what's happening with crypto cards.

Visa-backed crypto card spending grew 525% in 2025. Monthly card volume hit a record $607 million in March 2026. Visa now processes 97% of all crypto card transactions globally.

Think about what that means: users are loading stablecoins into accounts, and spending them with a Visa card at the corner store. The merchant sees a normal card payment. The user sees their crypto balance going down. The underlying rail is a stablecoin settling on-chain, then converting to fiat at the point of sale.

This is the hybrid model that every new banking product should be designed around. Not "crypto or fiat" — both, simultaneously, invisible to the end user.

The brands that figure this out first will own the next decade of consumer finance. The ones that wait will spend the decade after that trying to catch up.

What's actually holding people back

If the market is this big and the demand is this clear, why isn't every fintech founder building on stablecoin rails right now?

Three reasons.

First, complexity. Integrating stablecoin infrastructure alongside traditional banking rails — fiat accounts, card issuance, KYC/AML compliance, on-ramps, off-ramps — is genuinely hard. Most providers offer one piece of the puzzle. Very few offer the full stack.

Second, compliance. Until the GENIUS Act and MiCA, the regulatory picture was unclear enough to scare off anyone with institutional ambitions. That barrier is now largely removed, but the perception lingers.

Third, the build-vs-buy decision. Many founders default to building in-house because they assume that's what "serious" companies do. The reality is that building banking infrastructure from scratch — compliance frameworks, card programs, stablecoin integration, wallet architecture — typically costs north of $500,000 and takes 12 to 18 months. For most founders, that's a death sentence in a market moving this fast.

The smartest teams are skipping the build phase entirely. They're partnering with full-stack infrastructure providers that already have live products, licensed banking relationships, and stablecoin rails running in production. They launch in weeks instead of quarters — and put their capital into growth instead of infrastructure.

At Omni, this is exactly what we see across our portfolio. The founders who move fastest are the ones who stopped trying to become banking engineers and started focusing on what makes their product different. The infrastructure is a solved problem. The brand, the market, the user experience — that's where the real competition is.

The next 18 months

Here's what the data says is coming.

Stablecoin market cap is projected to exceed $1 trillion by late 2026. Citibank's base case puts total stablecoin issuance at $1.9 trillion, with a bull case of $4 trillion. Monthly stablecoin transaction volumes are on track to breach $1 trillion by the end of this year.

The Banking-as-a-Service market — the layer that sits between stablecoin rails and consumer-facing products — is at $29 billion and growing at nearly 18% annually. By 2031, it's projected to hit $66 billion.

87% of corporates surveyed by EY believe stablecoins create a competitive advantage. 77% say cross-border payments is the most compelling use case. 84% of U.S. merchants believe crypto payments will be mainstream within five years.

Every one of these numbers is a tailwind for anyone launching a banking product right now. The regulation is in place. The infrastructure exists. The demand is proven. The only question left is how fast you move.

The bottom line

Stablecoins aren't coming. They're here. They're not alternative finance. They're the new default rail for moving value globally.

If you're building a banking product, payment app, or financial service in 2026, the question isn't whether to integrate stablecoins. It's how quickly you can get to market with a product that uses them natively — alongside fiat, alongside cards, as a seamless layer your users never have to think about.

The window for early movers is closing. The infrastructure to launch is available. The market is waiting.

If you're ready to build, we should talk.
