Stablecoins Shift From ‘Trading Tool’ To Payments Rail As Volume Hits $4.5 Trillion In Q1, a16z Says

• Stablecoin transaction volume reached $4.5 trillion in Q1 2026, reflecting a shift from crypto trading tools to broader use in payments and financial services, according to a16z.
• Consumer-to-business payments rose 128% year-over-year, while adoption of stablecoin-linked payment cards continued to grow with deposits exceeding $300 million.
• The total stablecoin market cap reached $315 billion, with Tether accounting for roughly two-thirds of the market, as regulatory clarity in the U.S. continues to evolve.

Stablecoins are increasingly evolving into core global financial infrastructure, with transaction volumes reaching $4.5 trillion in the first quarter of the year, according to a report from Andreessen Horowitz (a16z).

The venture firm released a report on Friday, explaining that stablecoins were moving beyond cryptocurrency trading and store-of-value use cases, with adoption expanding into payments and financial services across global markets.

Following the passage of the GENIUS Act last year, which established a regulatory framework for stablecoin issuance and usage in the United States, transaction volumes accelerated, reflecting broader institutional and commercial adoption, the report said.

Consumer-to-business payments rose 128% year-over-year to 284.6 million transactions in the first quarter, while the use of stablecoin-linked payment cards increased, with monthly collateralized deposits exceeding $300 million.

On Stocktwits, retail sentiment around Tether’s price remained in the ‘bullish’ zone, while retail sentiment around USAT which is a bridged version of Tether’s USDT dropped to ‘neutral’ from ‘bullish’ over the past day.

Shift Toward Real-World Payments

Stablecoin usage is increasingly moving toward everyday payment activity. Asia accounts for the largest share of payment flows, followed by North America, as adoption expands across both cross-border and domestic transactions.

The report said circulation efficiency improved, with stablecoin velocity rising from 2.6 times at the start of 2024 to 6 times, indicating a shift from passive holding to active usage. Business-to-business payments are also gaining traction as companies adopt stablecoins for faster settlement and lower transaction costs.

Growth is also reflected in market size and concentration. According to a report released last week by Fidelity Digital Assets, total stablecoin market capitalization reached approximately $315 billion as of March 31, 2026, up $110 billion from the start of 2025.

Tether (USDT) remains the dominant issuer, with a market capitalization between $159 billion and $185 billion, accounting for roughly two-thirds of the market and serving as the primary liquidity layer across trading and payment flows.

Regulatory Momentum Builds In The US

The findings come as U.S. lawmakers continue to debate broader digital asset regulation. While the GENIUS Act has been enacted, the Clarity Act, which aims to define oversight for digital asset markets, is still awaiting markup.

The report said clearer regulation, along with lower costs and faster settlement enabled by blockchain infrastructure, is driving stablecoin adoption beyond speculative use.
