The technology industry has spent the better part of two decades obsessing over mobile-first strategy. But as artificial intelligence becomes the organizing principle of consumer computing, the real competition among OpenAI, Amazon, and Apple is shifting from controlling the handset to controlling the financial transaction that happens on it. The smartphone is no longer the destination. The wallet is.
This represents a fundamental realignment of power in fintech. For the past fifteen years, platform operators have treated payments as a feature of the device. Apple Pay, Google Pay, Samsung Pay—these were conveniences layered atop existing banking infrastructure. But the emergence of large language models as primary interfaces to digital life has triggered a reckoning. When an AI system becomes your primary contact point with the digital world—handling queries, executing commands, and making decisions on your behalf—it naturally becomes the arbiter of which financial services you access and under what terms. The smartphone, as a discrete device, loses its centrality. The AI layer, by contrast, gains unprecedented leverage over commercial transactions.
OpenAI's integration strategy reveals the urgency of this shift. Rather than building a consumer device, the company is positioning its language model as the intermediary through which users interact with commerce. Every query has the potential to be a transaction. Every recommendation, a payment opportunity. The architecture is fundamentally different from the smartphone model, which required users to unlock, navigate menus, and initiate action. A conversational AI system can embed financial behavior into natural language itself. "Can you order my usual coffee?" becomes not a voice command but a completed financial exchange, with the AI layer determining which vendor processes it, what payment method is used, and whether the transaction is bundled with other services.
Amazon's position in this ecosystem is particularly instructive. The company already operates payment infrastructure through Amazon Pay, a system that has struggled to gain traction as a standalone rival to PayPal or Stripe. But Amazon's integration of AI through Alexa and broader commerce operations positions it to become the default financial rail for purchases initiated through voice or conversational interfaces. The company's Whole Foods acquisition and AWS payments infrastructure create a closed loop—AI recommendations leading directly to transactions processed through Amazon's own rails, with minimal exposure to traditional banking intermediaries.
Apple's leverage is perhaps most consequential. With 2 billion active devices worldwide and Apple Pay already embedded in the operating system, the company controls both the device and the primary payment method for tens of millions of users. As Apple develops its own AI capabilities, the natural evolution is toward a unified model where device, AI assistant, and wallet are synonymous. Unlike OpenAI and Amazon, which must negotiate access to hardware and payment networks, Apple controls the entire stack. The company's introduction of AI features into iOS represents not merely a software update but a repositioning of the fundamental relationship between user, device, and financial service.
For traditional financial institutions and fintechs, the implications are severe. Banking has long operated on the assumption that the customer relationship is direct and durable. A person has an account, initiates transactions, and the bank processes them. Payment applications like Wise and Revolut disrupted this model by positioning themselves as the primary interface to money movement, but they still operate within the broader financial infrastructure, subject to regulations, banking licenses, and ACH or SWIFT rails. The AI-mediated transaction model threatens to make the bank—even the fintech—invisible. Users won't choose between banking services; their AI assistant will.
This dynamic creates an acute regulatory challenge. The European Central Bank, European Banking Authority, and equivalent bodies in North America have spent years establishing frameworks for Open Banking and payment infrastructure. These rules assume human agency and explicit choice at transaction points. But if an AI system is executing financial decisions autonomously, or recommending vendors and payment methods without explicit authorization for each transaction, existing frameworks may be inadequate. Questions of liability, consumer protection, and anti-competitive behavior become urgent when a single AI layer controls the transaction funnel.
The smartphone revolution of 2007 took fifteen years to fully reshape finance. The AI-mediated commerce revolution is likely to move faster. The next three years will determine whether payments remain a competitive feature set among payment networks and banks, or whether they become simply an execution layer controlled by whichever AI platform wins consumer trust. For fintech companies and financial institutions, the strategic question is no longer how to build a better mobile experience. It's how to maintain relevance when the primary interface to commerce isn't your app, your device, or your service—but an AI system that has no incentive to make you visible.
