Klarna reported Q1 2026 revenue of $1.0 billion, up 44% year over year, with GMV rising 33% to $33.7 billion and adjusted operating profit increasing to $68 million from $3 million a year ago. The company said it now serves 119 million active consumers and over 1 million merchants, with growth driven by broader wallet coverage across Pay Now, Pay Later, and Fair Financing.

Walmart switched its embedded buy now, pay later provider from Affirm to Klarna last year through OnePay, but both companies say they are still seeing strong volume from Walmart customers. Affirm CEO Max Levchin said many Walmart shoppers kept using Affirm through Affirm cards, while Klarna said its Walmart partnership is performing in line with expectations as Q1 revenue rose 44% to $1 billion.

OpenAI is partnering with Plaid to let ChatGPT users connect read-only financial account data and receive more personalized guidance on budgeting, debt repayment, and financial planning. The integration could move ChatGPT from generic advice to specific recommendations, such as which credit card to pay down first, though OpenAI says it is not a replacement for professional financial advice and users must still take actions themselves.

Modern vertical SaaS “Control Points” are not doomed by AI, but they must move urgently to become the System of Action before foundation models and Native AI startups move up the stack. The playbook is to win strategic product surfaces, replumb the company for product velocity, charge explicitly for valuable agents, and define moats around scarce workflows, data, and customer gravity.

a16z is investing in Stitch, an API-first operating system for financial institutions that includes a general ledger, core database, product software for cards, loans, and bank accounts, plus workflow integrations like KYC and KYB. Stitch is well-positioned in the Middle East, where financial services are growing rapidly and new institutions need modern core banking infrastructure built for clean APIs, data access, and AI-native workflows.

Banks have spent the last decade chasing digital efficiency while stripping away the human support systems many customers still rely on. Despite thousands of branch and ATM closures across the UK, surveys show even Gen Z customers continue visiting branches, especially when dealing with complex or stressful financial issues. The future of banking isn't fully digital or fully physical, but a hybrid model where AI and apps handle routine tasks while humans step in for trust, guidance, and problem-solving.

Companies are splitting into those rebuilding their operating model around AI and those waiting to have it done to them. This article defines 6 levels of AI adoption, with most companies stuck at Level 1 (personal productivity) and only a handful like Ramp and Allica Bank at Level 4. Three transformation paths are emerging: DIY, partnering with AI labs and their forward-deployed engineers, or having it forced by PE shareholders. Anthropic's new Claude for Small Business plugs into QuickBooks, PayPal, HubSpot, and others — running payroll, closing the month, and chasing invoices — essentially killing an entire category of vertical fintech startups, for free. The key warning: companies that don't move up the adoption curve face two endings — acquisition on someone else's terms, or irrelevance.

Coinbase will manage USDC liquidity on Hyperliquid under its Aligned Quote Asset framework, while Circle will serve as the technical deployer for cross-chain USDC infrastructure. The move effectively sunsets USDH, Hyperliquid's native stablecoin, after it failed to gain traction against roughly $5 billion of USDC supply on the platform.

Xero is bringing real-time accounting data directly into Anthropic's Claude, giving small businesses a new way to ask financial questions in plain English and instantly pull insights like cash position, overdue invoices, and profit trends. The integration allows users to interact with live financial data inside Claude without switching platforms, marking one of the clearest examples yet of AI assistants becoming embedded operating layers for SMB finance workflows. For Xero, which serves more than 4.9 million customers globally, the move also signals how accounting platforms are evolving from passive reporting tools into proactive AI-driven financial copilots.

Adyen, the financial technology platform of choice for leading businesses, today announced a new collaboration with SAP, deepening its partnership to support the launch of the SAP Unified Payment solution.

Revolut is exploring a private banking unit in the UK and parts of Europe as it looks to expand wealth management revenue from higher-net-worth customers. The fintech could launch the offering as soon as this summer, with a potential eligibility threshold of £500,000, though plans remain under discussion.

Digital payments may dominate the fintech conversation, but new Federal Reserve data shows cash usage has stabilized after a steep decline between 2017 and 2020. The average number of monthly cash transactions has remained largely flat since the pandemic, suggesting consumers still rely on physical money more than many in the industry expected. The trend is a reminder that banks and payment providers will likely need to support cash infrastructure for years to come, despite the continued push toward wallets, tap-to-pay, and other digital payment methods.

Embedded finance is often presented as a platform-led story. Marketplaces and software providers are integrating payments into their ecosystems to capture data and monetise flows. With global digital payments reaching £18.6 trillion last year, the scale of opportunity is clear. For policymakers and financial institutions alike, the more important question is not who embeds payments, but who controls the infrastructure in which they operate.

Amazon is replacing its standalone Rufus shopping chatbot with “Alexa for Shopping,” a new AI-powered assistant embedded across its app, website, and Echo devices.

Shopify says traffic from AI-powered shopping experiences grew 8x year over year.

The biggest risk with AI agents isn't that they become smarter than humans, but that companies can't reliably verify whether the systems are actually correct before they execute decisions at massive scale.
