Coinbase CEO Brian Armstrong has reinforced his prediction that autonomous AI agents will eventually conduct more daily transactions than all humans combined through cryptocurrency infrastructure, as Base payments using the x402 protocol have crossed over 100 million transactions according to Chainalysis data. In a recent post on X, Armstrong rejected the advice that people in crypto should pivot to AI, calling that framing 'zero-sum scarcity thinking'. He compared crypto to electricity and the internet, both of which work as base infrastructure that later technologies run on top of. Armstrong emphasized that autonomous software cannot operate inside traditional finance - agents cannot open bank accounts or wait 3 days for a wire, requiring fast, programmable and global settlement that blockchains and stablecoins can provide. This prediction focuses on transaction frequency rather than payment value, with software potentially paying small amounts for every API call, data request or computing task.
The latest developments come during a challenging year for digital assets, with Bitcoin (BTC) falling more than 25% in 2026 and US spot exchange-traded funds recording $4.5 billion of outflows in June. However, AI-linked equities have moved in the opposite direction, with the S&P 500 gaining roughly 9% this year and AI names accounting for almost all of that advance. Armstrong disputed competition concerns, arguing that AI being a megatrend takes nothing away from crypto and that both technologies serve different purposes in the financial ecosystem. The drawdown has also weighed on crypto-linked stocks and platform activity, making the timing of Armstrong's optimistic predictions particularly significant for the sector's recovery narrative.
Coinbase introduced Base in February 2023 as a low-cost Ethereum layer-2 network for onchain applications, which later became the main network for x402 payments due to its lower fees and faster settlement. Coinbase launched x402 in May 2025, an open protocol that uses the HTTP 402 'Payment Required' status code to let websites and APIs request stablecoin payments. Under this system, a client receives payment instructions, signs a blockchain transaction and gains access after the payment is checked. USDC serves as a common settlement asset because its price tracks the U.S. dollar, while Agentic Wallets allow developers to set spending and trading rules for AI systems without manual approval for each transaction. The Agentic.Market operates as a public discovery platform for x402-enabled services, requiring no accounts or API keys and offering live pricing, volume data, and integration support for both human developers and AI agents.
Chainalysis reported on June 3 that x402-linked payments on Base crossed 100 million transactions after about nine months of activity. The analytics company found that payments worth at least $1 made up 95% of the value transferred, with agentic payment wallets tending to be newer, held smaller balances and owned 550% more asset types than typical Base users. However, meme-coin farming drove much of the early transaction growth, limiting claims that all 100 million payments came from independent AI agents buying useful services. Automated scripts, incentive campaigns and other software activity can also create x402 transfers, though the report demonstrates growing x402 activity as the protocol matures. Outside Coinbase, companies have begun testing the protocol for travel, cloud services and online content, with Travala launching an AI hotel-booking system that lets agents search more than 2.2 million properties and pay with USDC on Base.
U.S.-listed cryptocurrency exchange Coinbase has significantly expanded its payment acceptance capabilities, with Coinbase Business users now able to accept USDC payments from AI agents beginning this week. According to Coinbase, this feature is powered by Coinbase Payments and native x402 support, enabling businesses to receive, track, reconcile and cash out agent payments from the same account used for other payment activity. The exchange offers rewards on eligible idle USDC balances with a 3.35% annual reward rate, though rates vary by region and may change. Coinbase notes that USDC payments do not carry chargeback risk because Coinbase does not act as a party to transactions between businesses and their customers. This expansion builds on the exchange's earlier partnership with Checkout.com, which has achieved a 13 percentage point increase in payment acceptance rate and supports the exchange's mission-critical payment infrastructure across more than 100 markets globally.
While industry builders recognize the potential of machine-speed finance, they highlight significant structural challenges. Tory Green, CEO of decentralized network io.net, noted that "agents don't just need money, but they need money that moves at machine speed" - our entire financial stack has evolved for human interfaces and money represents the first rail that needs to catch up. However, developers warn about potential risks in giving autonomous software agents direct control over financial assets. NeoSoul AI commented that "building the rails is cool, but giving an agent capital without a track record is wild" - the transition from agentic payments to an agentic economy requires a missing layer of reputation and memory, as you can't trust a blank slate with a crypto wallet. The market remains early, with Coinbase's products showing that machines can initiate blockchain payments, but adoption figures depend on how analysts classify agent activity, security measures, spending controls, identity rules and service quality. Coinbase will publish its second-quarter 2026 results on July 30 after U.S. markets close, which may provide investors with more detail on stablecoin revenue, Base activity and developer products, though the company has not said it will disclose AiFi revenue separately.
