A16z just posted a very impressive judgment, he said: AI agents are not here to swipe cards. They are here to rewrite the payment system. Most people are still using the "human click checkout payment" brain circuit to understand the future. Wrong. In the era of agents, the trading subject is not human. It is a digital executor that can operate 24 hours a day, be replicable, and scalable. And their payment methods—— Not like tourists. Will be like a local. 1、 Tourist payment vs local payment How do tourists pay? Temporary price comparison On site negotiation Pay by card one-time transaction What do locals do? long-term cooperation Negotiate the price in advance credit Batch settlement The core judgment of a16z is in one sentence: Agents will establish long-term supplier relationships like enterprises. It's not just a single card swipe. But rather pre negotiate the terms. 2、 Why are agents more like enterprises? Two reasons. one ️⃣ Good experience comes from 'pre design' You wouldn't want your travel agent to start making phone comparisons at checkout. A truly good agent has long been agreed upon: Who is a reliable supplier What is the price range When can I lock the warehouse This is not a retail payment. This is a B2B relationship. two ️⃣ Scale will crush small players Agents who book one million airline tickets per year, The price obtained will definitely be better than ordering 10 sheets per year. Scale enhances scale. In the end, only a few core agents will remain in each vertical domain. They will have: lower cost Stronger bargaining power Deeper system integration This is essentially the structure of the enterprise. 3、 Two payment relationships will exist simultaneously The future payment structure will split into two layers: User → Agent subscription fee Charge by task authorized amount Agent → Supplier Pre negotiated price Net-30 invoice bulk discount credit limit The latter is the real big head. And here's the problem—— Is a credit card suitable? 4、 Credit cards may seem perfect, but they are actually stuck On the surface, credit cards are very compatible: Global acceptance Built in arbitration Monthly Bill But the reality is: Not supporting micro payments Less than 1 cent is basically not acceptable 30 cent fixed handling fee model Technical architecture defaults to 'human approval' What is the payment scenario for agents? $0.001 computing power per second API call for micro billing High frequency cross-border small-scale settlement The cost structure of credit cards is fundamentally mismatched. What's even more troublesome is—— They lack the motivation to self revolutionize. This is the typical innovator dilemma. 5、 Stablecoins are prepared for agents The advantages of stablecoins are very intuitive: Global availability low cost No minimum handling fee programmable The key is: programmable. bill arbitration hosting Conditional payment credit limit They can all be written into the same system. You can: Pay $0.001 in computing power per second You can also settle a $50000 bill in one go The same track is completed. 6、 Where is the real blue ocean of entrepreneurship? A16z has actually named the direction. In the future, it's not just about 'issuing a stablecoin' that will explode. But rather, it revolves around the entire financial layer of the Agent ecosystem: Agent specific billing system Automatic arbitration mechanism On chain credit score Batch approval tool Cross system interoperability protocol Flow payment infrastructure Micro working capital network In other words—— This is a reconstruction opportunity for "Agent version Stripe+Visa+PayPal+Bank". And it's in a completely new payment paradigm. 7、 The most crucial sentence The payment relationship has strong path dependence. Once the agent and the supplier The first layer of relationship is built on stablecoins. In the next five years, it is highly likely that it will not return to the card swiping track. This is the real window period. AI is not just about grabbing jobs. It will rewrite the way money flows. And agent payment is likely to be the most underestimated infrastructure battlefield in the next decade.
