The theoretical phase of agentic commerce is ending as the actual rules of engagement take shape. Today on The Merchant Desk, we're unpacking how Stripe and Melio are positioning for machine-driven B2B payments, the dedicated protocol stack emerging to govern autonomous transactions, and a billion-dollar consolidation play in South Africa's retail landscape.
Stripe co-founder John Collison predicts a fundamental shift in online shopping where AI agents will handle product discovery, comparison, and purchasing on behalf of consumers. He argued on Tuesday that this will render traditional advertising and SEO strategies less effective, forcing brands to optimize their product data for AI algorithms rather than human search. Stripe is positioning its platform, including its Agentic Commerce Suite and Link product, to be the core payment infrastructure for this new era.
Why it matters
This is a clear articulation of the agentic commerce thesis from a major payments infrastructure provider. It signals that the core architecture of e-commerce—from discovery to payment—is being re-evaluated. For operators, this means the competitive landscape will shift from winning clicks to being selected by an agent, demanding a new focus on structured data, API-first product catalogs, and payment rails built for machine-to-machine transactions.
B2B payments platform Melio has launched an AI agent-powered network that allows buyers to pay suppliers without requiring suppliers to join a new platform. First detailed in mid-June and highlighted again on Tuesday, the agents autonomously log into supplier portals, identify preferred payment methods, execute payments, and reconcile remittance data. The goal is to reduce the friction and reliance on paper checks that have long plagued US B2B payments.
Why it matters
This is a practical application of agentic AI to solve a notoriously fragmented problem. By removing the need for bilateral supplier onboarding, Melio is changing the architecture of B2B payments. For an operator, this model demonstrates how AI agents can automate complex financial workflows, creating a significant opportunity to digitize accounts payable and receivable for SMBs, a key value proposition in merchant tech.
Nayax, a commerce and payments platform for unattended retail, has launched an AI layer within its MoMa mobile management application. Announced Tuesday, the new features provide an AI Assistant for querying business data, AI-based planogram suggestions to optimize product mix, and visual recognition to configure machine layouts from a photograph. The tools are aimed at democratizing operational intelligence for small and mid-sized vending operators.
Why it matters
This is a strong case study of vertical SaaS AI in action. Nayax is using AI not as a flashy add-on, but as a practical tool embedded directly into operator workflows to solve specific problems like product mix and restocking. This creates a powerful competitive moat, tying operational intelligence directly to its underlying payments infrastructure and making the platform stickier for its target market of unattended retail.
New Visa rules for stored-credential transactions, which became fully enforced on July 1st, are reportedly causing elevated 'soft decline' rates for subscription merchants. The rules require more precise signals for transaction intent, particularly affecting businesses with variable pricing or trial offers. Brands are now being forced to re-architect their billing and dunning systems to comply and maintain authorization rates.
Why it matters
This highlights the significant operational overhead that evolving card network mandates place on merchants and their payment providers. For a fintech operator, this is both a threat and an opportunity. It underscores the value of sophisticated billing infrastructure that can abstract away this complexity, reduce churn from failed payments, and provide a clear compliance pathway for merchants managing recurring revenue.
Mastercard is expanding its use of stablecoins, announcing a pilot Wednesday with SoFi Technologies and Galileo for card transaction settlement. Building on the HSBC B2B agent pilot we tracked earlier this month that supported SoFiUSD, this new initiative uses the same stablecoin to streamline backend interbank clearing and liquidity, leaving the consumer point-of-sale experience unchanged.
Why it matters
This move by a major card network to integrate regulated stablecoins into its core settlement flow is a significant validation of the technology for mainstream finance. It signals a future where tokenized assets could run in parallel with traditional rails, improving the speed and capital efficiency of the global payments system. This directly challenges similar stablecoin initiatives being pursued by Visa.
HabariPay, the fintech subsidiary of Nigerian banking giant GTCO, announced plans on Tuesday to deploy 200,000 Point-of-Sale (PoS) terminals in 2026. The aggressive expansion aims to capture a significant share of Nigeria's merchant acquiring market, directly challenging the dominance of fintechs like Moniepoint, OPay, and PalmPay that have built extensive agent networks.
Why it matters
This signals a strategic counter-offensive by Nigeria's incumbent banks against the fintechs that have dominated the agency banking and merchant services space. For the Nigerian payments landscape, this means intensified competition on the ground, likely leading to pressure on terminal pricing and merchant fees. It's a classic case of a well-capitalized incumbent leveraging its balance sheet to reclaim market share.
South African fintech Float, which offers a card-linked installment platform, announced its international expansion with a launch in the UK on Tuesday. The service allows shoppers to split purchases into monthly installments using their existing credit cards, without requiring a new credit application or a separate BNPL account.
Why it matters
A South African fintech expanding into a competitive market like the UK is a notable milestone. Float's model, which leverages existing credit card rails rather than originating new credit, represents a capital-light and less risky approach to BNPL that is gaining traction globally. It's a smart strategy that sidesteps much of the regulatory scrutiny facing standalone BNPL providers.
African payments leader Flutterwave has received a strategic investment from Circle Ventures, the venture arm of the USDC stablecoin issuer. The partnership, announced Tuesday, will integrate USDC settlement directly into Flutterwave's payment flows, enabling near-instant, lower-cost settlement for merchants and businesses operating across the continent.
Why it matters
This move deepens the trend of African payment gateways adopting stablecoins as a core part of their cross-border infrastructure. By integrating USDC, Flutterwave can reduce its reliance on traditional correspondent banking, lower FX costs, and offer faster settlement to its merchants. It's a clear operational play to improve unit economics on cross-border transactions.
Abu Dhabi National Oil Co's retail unit, Adnoc Distribution, has agreed to acquire Shell's downstream operations in South Africa for an enterprise value of $1 billion. The deal, announced Tuesday, includes 580 Shell-branded retail stations and their associated convenience stores, as well as wholesale fuel, aviation, and lubricants businesses. Adnoc will retain the Shell brand and sell a 28% stake to a local empowerment partner, with the transaction expected to close in 2027.
Why it matters
This is a landmark transaction for South Africa's fuel retail sector, introducing a new, deep-pocketed international player. The acquisition will intensify competition for BP, TotalEnergies, and others, likely driving significant investment into the forecourt experience, convenience retail, and associated payment technologies. For operators in merchant tech, this signals a major new client and a catalyst for modernization across the entire fuel and convenience vertical.
The fragmented AI agent ecosystem is beginning to consolidate into a layered protocol stack. A new analysis published Tuesday shows standards emerging for distinct functions: Anthropic's Model Context Protocol (MCP)—which we recently noted as the emerging baseline for enterprise tool calling—is being joined by Google's Agent-to-Agent (A2A) for peer communication, the W3C-backed WebMCP, and the Agent Payments Protocol (AP2) for machine-native transactions.
Why it matters
Standardization is the critical step needed to move agentic commerce from isolated pilots to a scalable ecosystem. The emergence of a payments-specific protocol (AP2) alongside the MCP layer we've tracked provides the dedicated infrastructure for secure, authorized transactions between machines. For a payments operator, understanding this evolving stack is essential.
The crisis in digital game preservation we've been tracking—contrasting starkly with Sega's recent nostalgic push back to physical cartridges—is escalating following Sony's confirmed 2028 exit from physical disc production. On Tuesday, Frank Cifaldi of the Video Game History Foundation stated that piracy has become the only effective method for long-term preservation, compounding a blow dealt by Germany's largest video game archive losing its public funding.
Why it matters
The industry's decisive shift to digital-only distribution is creating a cultural crisis. Without physical media or well-funded archives, decades of video game history are at risk of being lost to server shutdowns and licensing issues. This forces a difficult conversation about the role of piracy not as theft, but as a necessary, if legally fraught, act of cultural preservation.
Equity Group, the AfricaNenda Foundation, and the Gates Foundation have formed a partnership to accelerate the development of Digital Public Infrastructure (DPI) across Africa. The initiative, announced Tuesday, will focus on creating interoperable digital payment systems and identity frameworks, starting in Rwanda. Equity Group CEO Dr. James Mwangi has been named a 'Continental Champion' to lead the private-sector effort.
Why it matters
This is a heavyweight coalition tackling one of the biggest brakes on African commerce: fragmentation. Building shared, open standards for payments and identity (DPI) is a prerequisite for a truly functional single market under AfCFTA. For operators, this initiative promises to create a more unified landscape, making it easier to build and scale pan-African products.
The Infrastructure for Agent Commerce Solidifies From Stripe's vision of AI-led discovery to Melio's agentic B2B payment network, the focus is shifting to building the foundational rails, protocols, and governance for a machine-driven economy.
Consolidation and Competition Reshape SA Retail Adnoc's $1B acquisition of Shell's fuel stations and the continued dominance of Checkers Sixty60 signal major shifts in the South African retail landscape, driving new investments and competition in forecourt and grocery services.
African Fintech Focuses on Foundational Infrastructure Across the continent, major initiatives are underway to build the core digital public infrastructure needed for growth, from a partnership involving Equity Bank and the Gates Foundation to a new unified payment API in Liberia.
Game Preservation Becomes a Crisis Point Sony's move away from physical media, coupled with the loss of funding for major archives, has intensified the debate on game preservation, with many experts now viewing piracy as the only viable long-term solution for ownership.
The 'Sovereign AI' Stack Takes Shape in Africa Partnerships like TrendAI/Anthropic in South Africa and acquisitions like Backbase/Kasisto are focused on building locally governed AI and data infrastructure to address data sovereignty and compliance, a key hurdle for enterprise adoption on the continent.
