Stripe Warns Blockchains Must Hit 1 Billion TPS to Power the AI Agent Economy

Imagine a world where AI agents handle every online purchase, subscription, and payment on your behalf silently, instantly, and around the clock. That future, according to payments giant Stripe, is nearer than most think, and it demands a level of blockchain scalability that no network on earth can currently deliver. In a sweeping annual letter published this week, Stripe CEO Patrick Collison and co-founder John Collison warned that blockchain transactions per second may need to scale to one billion to support the coming wave of autonomous AI commerce.

Crucial Context and Impact

The letter, posted to X on Tuesday, comes as part of Stripe's annual review of 2025 performance and forward-looking predictions. Central to the co-founders' vision is the growing role of AI agents on blockchain infrastructure software programs capable of autonomously executing internet transactions without human input. Collison and Collison argue that these agents will "most likely soon be responsible for most internet transactions," fundamentally transforming the scale at which payment networks must operate. The implication is stark: today's blockchain infrastructure is dangerously underprepared for what lies ahead.

Supporting Facts and Data

The gap between current capability and future need is enormous. According to data from Chainspect, Internet Computer Protocol and Solana are the current leaders in blockchain transactions per second, processing roughly 1,196 and 1,140 TPS, respectively, the only two networks currently exceeding 1,000 TPS. At their historical peaks, they reached 25,621 TPS and 5,289 TPS, with theoretical maximums of just 209,708 TPS and 65,000 TPS. Against a target of one billion TPS, even the best-performing chains today fall short by several orders of magnitude, underscoring the urgency of scalability in blockchain development. The stripe crypto intersection is already showing strain. The letter noted that a memecoin frenzy on a major blockchain last year delayed payouts for one Bridge user by over 12 hours and spiked per-transaction fees by 35 times.
