↓ -2%Stripe executives told investors in a letter obtained by Axios that they believe the "singularity" — when artificial intelligence surpasses human intelligence — arrived on 1 January 2026. The payment processor has been operating on that assumption ever since. CEO Patrick Collison, president John Collison, and president of technology and business William Gaybrick cited "a large inflection in long-run trends", including a significant increase in new firm creation. They join other tech leaders like OpenAI's Sam Altman and Tesla's Elon Musk in declaring the singularity's arrival, though several AI experts dispute this view. The company announced it was acquiring OpenRouter, an AI model marketplace startup. Stripe's first-half revenue rose 41% year-over-year.
Stripe to acquire OpenRouter in roughly $7.5 billion bet on AI's future. 0 Comments Payments giant Stripe just made one of its boldest moves yet, reaching beyond its familiar territory of processing transactions and into the fast-moving world of artificial intelligence infrastructure. The company announced Wednesday it has agreed to acquire AI routing platform OpenRouter, a deal that reportedly carries a price tag around $7.5 billion and has three law firms steering the transaction through to close. Why Stripe wants an AI traffic cop. In its deal announcement, Stripe framed the acquisition as a natural extension of its existing playbook rather than a departure from it. The company said OpenRouter will expand its AI capabilities well beyond payments and billing, layering new functionality on top of the tracking and billing tools Stripe has already built for businesses. What OpenRouter actually does. Think of OpenRouter as a switchboard operator for artificial intelligence: it gives businesses access to hundreds of different AI models through a single platform, automatically directing each request to whichever model best balances cost, speed and performance - sparing companies the headache of juggling multiple AI providers on their own. Stripe said the platform already counts major names among its users, including Nvidia, Zoom and Lovable. The price tag, confirmed quietly. Stripe itself declined to disclose financial terms publicly, and OpenRouter did not respond to a request for additional information. But a person familiar with the transaction confirmed the purchase price sits at roughly $7.5 billion - a figure that underscores just how much value the market now places on AI infrastructure plays, even ones that don't manufacture chips or build foundation models themselves. A play for cost efficiency. According to Stripe's announcement, folding OpenRouter into its ecosystem will help customers cut their AI spending by intelligently matching each request to the most cost-effective model capable of handling it - building directly on Stripe's existing tools for tracking and billing AI usage, rather than replacing them. The strategic vision. Stripe framed the combination as addressing both sides of the profitability equation at once. "Together, Stripe and OpenRouter will be able to help companies manage both sides of profitability in the AI era: maximizing revenue and efficacy while minimizing costs," the company said in its announcement - a pitch aimed squarely at businesses trying to harness AI without watching their budgets spiral out of control. The legal team guiding the deal. Fenwick & West LLP is representing Stripe in the transaction, with a team led by Ken Myers and Victoria Lupu steering the acquisition through what promises to be one of the more closely watched AI-adjacent deals of the year.
Stripe told investors that January 1st marked the "beginning of the singularity," a major inflection point in longterm trends, according to a letter obtained by Axios. The payments giant said first-half revenue rose 41% year-over-year and free cashflow increased 43%. Stripe confirmed its acquisition of OpenRouter for more than $8 billion, mostly in stock. The company says 88% of the Forbes AI 50, including OpenAI and Anthropic, are building on its platform. The share of its revenue from AI and crypto companies has more than doubled year over year. Stripe was valued at $159 billion in February during an employee tender offer, up from $91.5 billion a year earlier. The company is also pursuing an acquisition of PayPal with Advent International, reportedly offering $53 billion.
Stripe has agreed to acquire OpenRouter, an AI model gateway and routing platform used to optimise token usage across more than 400 models from over 80 providers.

The card, developed in partnership with payment infrastructure company Stripe, can be used at any merchant that accepts Visa. It allows users to hold and spend more than 600 currencies and cryptocurrencies, with rewards of up to 2% back in U.S. dollars or Bitcoin on eligible purchases. Expanding from Europe to the U.S. Market The debit card was previously introduced in the United Kingdom and Europe, where it gained traction among crypto users seeking to integrate digital assets into everyday spending.

The rewards program - offering up to 2% back in USD or BTC - adds an incentive for everyday use, potentially encouraging wider adoption of crypto payments. Implications for Crypto Payments Adoption The launch of Krak's debit card in the U.S. signals a maturing crypto payments ecosystem. As regulatory clarity improves and consumer interest grows, crypto debit cards are becoming a bridge between traditional finance and digital assets. For Kraken, this move strengthens its ecosystem beyond trading, aiming to make crypto more practical for daily transactions. For users, it offers a convenient way to spend digital assets while earning rewards, without needing to manually transfer funds to a bank account.
