$5 Billion in Acquisitions, $10 Billion Monthly Volume: Stablecoin Infrastructure Goes Mainstream 🚀

Welcome to Advance Genie, weekly newsletter that helps operators in highly stigmatized industries find alternative financing methods.

October 2025 marked the moment stablecoin payment rails went from experiment to enterprise infrastructure. 

Payment giants spent over $5 billion acquiring stablecoin companies. Actual usage hit $10 billion monthly.

The world's largest asset manager launched a trillion-dollar fund to back stablecoin issuers.

Mastercard, Visa, Stripe, and others are now betting billions that stablecoins will power the next generation of commercial payments.

The infrastructure wave isn't theoretical. It's operational. 

And it bypasses standard banking relationships that have blocked businesses for so long.

Payment Giants Spend $5+ Billion on Stablecoin Infrastructure

Three big acquisitions in nine months.

Mastercard is acquiring Zerohash for nearly 2 billion, according to sources familiar with late-stage talks reported October 29. The Chicago-based startup builds stablecoin and blockchain infrastructure, including payment rails and crypto trading capabilities.

Days later, Coinbase entered late-stage talks to acquire BVNK for roughly $2 billion, with the deal expected to close late this year or early 2026. BVNK's platform lets merchants accept stablecoin payments and manage treasury operations.

Stripe already set the market in February, acquiring Bridge for $1.1 billion.

That’s over $5 billion deployed on stablecoin payment infrastructure this year.

These aren't crypto startups buying crypto companies. 

These are payment processors and networks that move trillions annually through traditional rails now building parallel stablecoin infrastructure.

Visa chose a different path. 

Rather than acquire, the company is building its own stablecoin settlement platform. 

During its October 28 earnings call, Visa CEO Ryan McInerney revealed the network now supports four stablecoins across four distinct blockchains, with the ability to convert to over 25 traditional fiat currencies.

"We are adding support for four stablecoins, running on four unique blockchains, representing two currencies that we can accept and convert to over 25 traditional fiat currencies," McInerney said.

The strategy isn't to replace card networks with blockchains. It's to make existing networks blockchain-capable. 

Stablecoins flow through familiar channels. Compliance and AML guardrails remain. Speed and cost improve dramatically.

Stablecoins represent over $250 billion in circulating value. A USDC transaction can settle $10 million in 10 seconds with instant finality. Traditional wire transfers take 72 hours and require correspondent banks.

When payment infrastructure companies spend billions to own the orchestration layer, they're not betting on potential. 

They're responding to demand that already exists.

Payments Hit $10 Billion Monthly

The usage data supports the infrastructure spend.

Over $10 billion moved through stablecoins in August alone for goods, services, and transfers, according to blockchain data provider Artemis. That's up from $6 billion in February and more than double the volume from August 2024.

At this pace, stablecoin payments will reach a $122 billion annualized run rate.

The growth accelerated immediately after President Trump signed the GENIUS Act into law on July 18, 2025. 

The legislation established federal regulations for stablecoin issuers and requires them to back tokens with highly liquid assets like Treasury bills.

"If you look at stablecoin supply on a certain trend, and then right after GENIUS passed, the trend does inflect even more," said Andrew Van Aken, data scientist at Artemis. "We certainly think it has had an incremental impact."

Business-to-business transfers now dominate stablecoin payments. 

B2B payments hit $6.4 billion monthly, representing nearly two-thirds of total volume and marking 113% growth since February. 

This is the first time business payments exceeded peer-to-peer consumer transactions, which held steady at $1.6 billion monthly.

Companies are using stablecoins to bypass traditional international banking delays.

Businesses are "fed up with this very cumbersome send deposit here to this bank, which then sends another bank, which sends another bank," Van Aken explained.

With an average business stablecoin payment of $250,000, speed matters most. Companies use stablecoins to avoid routing payments through multiple correspondent banks in the traditional system.

Banks have taken notice. 

Even Zelle, the bank-owned service that facilitates consumer money movement, announced plans to expand internationally using stablecoins to enable cross-border transfers.

Stripe Launches Stablecoin Subscriptions

The infrastructure acquisitions aren't about future capabilities. 

The tools are operational today.

In October, Stripe launched stablecoin subscription payments in private preview for U.S. businesses. 

The feature supports recurring payments in USDC over Base and Polygon blockchains, with automatic settlement in fiat currency.

The innovation solves a fundamental blockchain limitation. Typically, wallet owners must manually "sign" each transaction. Stripe built a smart contract that lets customers save their wallet once and authorize recurring payments, just like saving a credit card. Over 400 wallets are supported.

The cost advantage is significant. 

AI company Shadeform shifted approximately 20% of its payment volume to stablecoins, cutting transaction costs in half while achieving near-instant settlement.

Stripe serves 30% of businesses with recurring business models. 

For frontier operators who face inflated "high-risk" processing rates of 4-6% compared to 2-3% for standard merchants, a 50% cost reduction changes unit economics.

Coinbase is building similar infrastructure. 

The company announced Coinbase Business, a platform businesses can use for payments and invoicing. BVNK's merchant acceptance capabilities, which Coinbase is acquiring, will expand these offerings.

Coinbase reported that almost 20% of its third-quarter revenues came from stablecoins, according to its shareholder letter released in October. During the earnings call, executives confirmed they're continuing to pursue acquisitions in payments.

The pattern: Payment platforms that historically excluded frontier operators due to "reputational risk" are now building infrastructure that doesn't discriminate based on industry classification.

BlackRock's $1 Trillion Milestone, FASB Votes for Accounting Clarity

Institutional validation arrived from an unexpected source.

BlackRock just announced that its Cash Management business surpassed the $1 trillion milestone in assets under management, reaching $1,005 billion. 

Days later, the firm introduced a strategic update to its BlackRock Select Treasury Based Liquidity Fund (BSTBL).

The fund's new investment strategy aligns with the requirements of the GENIUS Act, enabling it to serve as a reserve asset for payment stablecoin issuers. 

BlackRock structured the fund to hold overnight repurchase agreements and short-term U.S. Treasury instruments, meeting the liquidity and backing requirements stablecoin issuers need.

"We're seeing increasing demand from stablecoin issuers and clients seeking innovative, compliant reserve management solutions," said Jon Steel, Global Head of Product and Platform within BlackRock's Cash Management business. "We believe it positions BlackRock as one of the reserve asset managers of choice for the digital payments ecosystem."

BlackRock is the third largest Rule 2a-7 money market fund provider globally. 

When a firm managing this scale launches products specifically for stablecoin backing, the asset class has moved from speculative to institutional.

Accounting legitimacy followed. 

Financial Accounting Standards Board (FASB) voted 6-1 to add stablecoin accounting to its technical agenda. The decision follows the GENIUS Act and addresses how companies should record and disclose stablecoin holdings on balance sheets.

A preliminary framework is expected by mid-2026. If stablecoins qualify as "cash equivalents" under U.S. GAAP, they'll transform liquidity reporting, working capital classification, and financial ratios.

The combination of federal regulation, institutional reserve backing, and accounting clarity removes the three barriers that prevented enterprise stablecoin adoption.

What This Unlocks for Frontier Operators

The infrastructure wave solves problems traditional banking created.

Cost advantage that compounds. Shadeform's 50% cost reduction matters most when current "high-risk" merchant rates are 4-6% versus 2-3% for standard businesses. For operators processing millions annually, the savings fund growth instead of inflated fees.

Speed advantage that enables growth. Stablecoins settle $10 million in 10 seconds versus 72 hours for traditional wires. For businesses managing tight working capital, near-instant settlement eliminates the float that strains cash flow.

B2B infrastructure where it matters most. Business payments grew 113% to $6.4 billion monthly. The average stablecoin payment is $250,000. Frontier operators are primarily B2B — suppliers, manufacturers, distributors. The infrastructure is being built for exactly the transaction types these businesses process.

Alternative to discriminatory banking. Stablecoin infrastructure doesn't underwrite industry classification. It validates transaction legitimacy. When payment networks like Visa and Mastercard build stablecoin capabilities, merchant acceptance expands without requiring traditional banking relationships that exclude frontier operators.

The decision calculus isn't "should we explore crypto."

The decision calculus is "which stablecoin payment tools fit our business model today."

The alternative finance rails aren't coming. They're operational today.
