Stripe Sessions 2026 觀察：Stripe 把加密圈五年沒幹成的事，一晚上幹完了

Original Author: Xiaobing, TechFlow

On April 29, San Francisco Moscone West, Stripe Sessions 2026 kicked off.

As the keynote entered its second half, the lights dimmed. On the big screen appeared an image that made the entire audience raise their phones: Sam Altman, wearing his iconic beige sweater, seated on a light-colored sofa opposite Stripe President John Collison.

Those familiar with the scene smiled knowingly: This was Sam's second time on the Stripe Sessions sofa. The first was in May 2023, less than six months after ChatGPT had taken off. Back then, Sam was still debating with John about whether AI posed an "existential risk."

Three years later, things have changed drastically.

Sam's OpenAI has become a behemoth valued at $500 billion with 900 million weekly active users; Stripe's valuation has surged 70% over the past year to $159 billion; and the Agentic Commerce Protocol (ACP), jointly launched by the two companies in September 2025, already allows ChatGPT users to directly order Etsy and Shopify products within the chat interface.

Sam's appearance this time is a signal in itself: OpenAI's commercialization channel for its 900 million weekly active users is being bet on Stripe's infrastructure.

And across from the sofa where he sat, behind John on the big screen, was the core number from this year's keynote: 288.

That's the number of new products and features Stripe announced in one go at this year's Sessions. Nearly 9,000 people sat in the audience, 1.32 times more than last year. Patrick Collison joked at the start that this didn't even count "the agents you secretly brought in."

For the crypto industry, at least 60 of these 288 updates directly touched its "core territory," and the person endorsing them on stage was none other than Sam Altman.

Flattening the 288 Updates, There Are Really Only Three Things

If you click on Stripe's official post, "Everything we announced at Sessions 2026," you'll be inundated with product names: Checkout studio, Reader T600, Authorization Boost, Smart Disputes, Workflows, Custom objects, Stripe Console... Each comes with status tags like "preview," "GA," or "private preview," resembling the Jira board of some SaaS company.

But as an editor with a Claude MAX account, let me tell you: All these products are essentially answering just three questions.

First question: How does money cross borders? The answer is stablecoins.

Second question: What if the buyer isn't a person but an AI agent? How do you collect payment? The answer is the Agentic Commerce Suite + Machine Payments Protocol.

Third question: What if merchants want to use Stripe like a bank? The answer is the full-stack launch of Treasury.

Linking these three questions, you'll see Stripe is doing something almost no one is openly discussing: Using its payment company identity for compliance and distribution, it's taking the things the crypto industry has repeatedly tried but failed to bring mainstream over the past five years—stablecoins, agent economy, on-chain settlement—and stuffing them all at once into the pipes already laid by Visa, Mastercard, and PayPal.

The disruptive power of this lies in: It doesn't require users to know they're using blockchain.

Stripe May Have Already Won the Stablecoin Battle

First, look at some staggering data.

John Collison showed a chart at the 2025 Sessions: Bridge (the stablecoin infrastructure company acquired by Stripe) had a payment volume growth curve in its first 24 months steeper than Stripe's own at the same period. This was a rare moment where Stripe was "outdone by its own investment target"—a stablecoin pipeline that started less than two years ago outpaced the growth of Stripe, which dominated online payments for a decade.

By 2026, that curve hasn't turned.

At this year's Sessions, Stripe's updates around stablecoins can only be described as full-stack:

• Treasury stablecoin accounts expanded to 41 new markets, plus over 100 previously, meaning businesses in 150+ countries can use Stripe to store stablecoins and make cross-border payments. Patrick posted on X: "This is the biggest international launch we've ever done."
• Stripe Issuing launches stablecoin-backed debit cards covering 30 countries, allowing users to spend their stablecoin balances directly.
• Bridge now supports multiple stablecoins like USDG, CASH, and USDSui, with cross-chain coverage across Tempo, Plasma, Celo, and Sui.
• Privy enables stablecoin balances to be directly connected to Morpho's DeFi yields, meaning users' "current accounts" could theoretically earn DeFi returns passively.
• Crypto Onramp supports headless integration and a full KYC-free mode for transactions up to $500—a treat for crypto app developers, making the onramp experience as smooth as Apple Pay.

Put these together—what do you see?

A complete "stablecoin shadow banking" system. Cross-border receiving, storage, interest accrual, spending, withdrawal, cross-chain—things traditional crypto exchanges tried for five years without perfecting, Stripe has connected the full stack in one year.

Even more critical is its distribution capability. Stripe now covers over 16,000 platforms and 11 million businesses globally. When you receive a stablecoin payment from Ghana on Shopify, pay delivery drivers with stablecoins on DoorDash, or receive stablecoin subscriptions on Substack, Stripe's pipes are behind it all.

Crypto purists might say: "This isn't real crypto; it's centralized." But the market doesn't care. The market cares about one thing: money moving faster, cheaper, and with less friction.

At last year's AMA, Patrick was asked if Stripe would issue its own stablecoin. His response was telling: "We don't plan to. Our goal is to catalyze stablecoin adoption."

The Agent Economy: Stripe, Visa, and Mastercard Join Forces to Make "AI Paying" Like TCP/IP

What truly took my breath away at this year's Sessions was something else.

It's called the Machine Payments Protocol (MPP).

This was actually teased on March 18, when Tempo, the L1 blockchain co-incubated by Stripe and Paradigm, launched its mainnet alongside the MPP protocol. But back then, most people, including me, dismissed it as just another "x402 killer" crypto project.

We were wrong.

At Sessions, Stripe integrated MPP into a bigger narrative: Agentic Commerce Suite.

Here's the story:

• Your online store can now be "seen by AI agents." Merchants upload product catalogs on the Stripe Dashboard and authorize agent access. The underlying standard is the ACP (Agentic Commerce Protocol), an open-source protocol jointly published and governed by Stripe and OpenAI in September 2025. Sam's appearance at Sessions was essentially to endorse ACP.
• Stripe partnered with Meta so products in Facebook ads can be ordered directly by AI.
• Stripe partnered with Google to integrate AI Mode and Gemini into the Universal Commerce Protocol (UCP).
• Link launched an agent wallet, allowing users to authorize AI agents to make payments with their Link wallet while retaining approval and visibility.
• MPP enables agents to make micropayments, subscription payments, and even streaming payments on Stripe, supporting both stablecoins and fiat.

Notice the subtle landscape: Stripe holds two agent commerce protocols simultaneously—ACP with OpenAI, and MPP with Tempo, Visa, and Mastercard.

The former leans toward the application layer ("how agents place orders in ChatGPT"), while the latter leans toward the payment layer ("how agents settle on-chain, on cards, in wallets"). Google launched its own UCP, and Coinbase went solo with x402, but Stripe is the only company that has established standard partnerships with OpenAI, Visa/Mastercard, and Google simultaneously.

That's why Sam had to come in person.

Connecting the dots: When you have ChatGPT book a flight for you, Claude buy a gift, or some agent manage your SaaS subscriptions, the money flowing behind it will pass through Stripe.

And Stripe's smartest move this time was not doing it behind closed doors. MPP is open-source and rail-agnostic. Visa has already extended it to credit card payments, Lightspark to the Bitcoin Lightning Network, and Stripe to BNPL services like Klarna and Affirm.

This "I set the standard, everyone uses it" approach reminds me of one thing: This is how TCP/IP won too.

Even more impressive is MPP's design. It has a primitive called "sessions". An agent gets a one-time authorization limit and can then make continuous micropayments without needing on-chain confirmation each time.

Sound familiar? This is what the Lightning Network tried but failed to achieve. Stripe, with a payment company's engineering perspective, turned the "on-chain for trust, off-chain for speed" architecture into a product that truly works.

By the day of Sessions, MPP's payment directory already had over 100 integrated parties, including Alchemy, Dune, Anthropic, OpenAI, Shopify, DoorDash, Mastercard, Nubank, Revolut, Standard Chartered, Deutsche Bank...

This is a partner list any crypto protocol would drool over.

Stripe Treasury: Silicon Valley Founders' "One-Stop Finance," Quietly Turning into a Commercial Bank

If the first two pieces were gifts for the crypto and AI circles, the third, Stripe Treasury, is a direct attack on traditional banking in Silicon Valley.

This year's Treasury updates essentially break apart and sell a commercial bank piece by piece:

• Deposits: US and UK business Treasury accounts support holding 15 currencies.
• Payments: Internal Stripe transfers between US merchants are free and instant.
• Spending: Stripe launches its own Mastercard with 2% cashback.
• Earnings: Treasury balances can earn Stripe credit points to offset processing fees.
• Funding: Atlas founders can receive SAFE investment funds from investors via Treasury, supporting ACH, wire transfers, and stablecoins.
• Cross-border: Treasury balances are backed by Privy's non-custodial wallet, enabling instant cross-border transfers to 150+ countries.
• AI Integration: Agent-ready financial accounts allow AI agents to check balances, pay bills, issue cards, and manage cash flow, with human-in-the-loop for critical operations.

Put these together: Stripe has quietly issued a "commercial bank + investment bank + wallet + AI financial assistant" all-in-one package to every small business using its platform.

The most critical detail behind all this is Privy's non-custodial wallet.

When Stripe acquired Privy in 2025, most people thought it was just a minor crypto wallet acquisition. But now you see: The foundation for Treasury's rollout in 150 countries is entirely built on Privy's non-custodial wallet architecture.

This means that the most valuable thing for traditional banks—the "account"—has been redefined by Stripe using stablecoins and non-custodial wallets.

When a developer in Nigeria registers an account on Stripe, they are essentially obtaining a Privy wallet. This wallet can receive stablecoins and fiat deposits, and is connected to Bridge for cross-border clearing and Morpho for DeFi yields.

Throughout this process, they never need to know the word "blockchain."

Stripe's Dual AI Narrative: Infrastructure for Merchants, Models for Itself

Another easily overlooked point from Sessions: Stripe is using AI to rewrite itself.

Last year, Stripe launched the "Payments Foundation Model," a payment base model trained on hundreds of billions of transactions. The upgraded version this year reportedly increased fraud detection accuracy by 64%.

And the newly launched Stripe Console is an agentic execution environment embedded directly in the Dashboard. You ask in natural language, "Why did my conversion rate drop last Tuesday?" and it gives you a cross-product diagnosis. You tell it, "Send reminders to all customers who haven't paid in the last 30 days," and it executes, asking for your confirmation before important actions.

Custom objects let you model your own business data within Stripe, calling it like a database.

Stripe Database gives you a one-click, real-time synced Postgres read-only database—something a data company would charge a year's subscription for separately.

Workflows are now GA, supporting loops, third-party actions, and Connect platform calls.

Put it all together: Stripe is evolving from an SDK company into an "AI-native operating system." Merchants aren't just collecting payments on Stripe; they're running companies, hiring agents, managing operations, and making decisions on Stripe.

Why Does This Matter for the Crypto Industry?

By this point, many readers might be asking: What does this have to do with crypto?

In my assessment: Stripe Sessions 2026 is a "watershed moment" for stablecoins and the agent economy entering the mainstream.

Over the past five years, the crypto industry has repeatedly told the story that stablecoins are Web3's "killer app." And while on-chain stablecoin supply has indeed grown remarkably, the vast majority of transactions still circulate between CEXs, market makers, and arbitrageurs. Real consumer commerce and B2B cross-border payment scenarios have barely entered the picture.

Why? Because of barriers: KYC, wallets, private keys, gas fees, on/off ramps, compliance—any one of these can deter a legitimate business.

What Stripe has done this time is hide all these barriers behind its already-proven SaaS experience.

Merchants click "enable stablecoin payments" on the Stripe Dashboard to start receiving USDC, USDG, and USDB; developers add a parameter to the PaymentIntents API to let AI agents pay via the MPP protocol; startups register a US company on
