- Stripe executives predict that blockchains may need to process up to one billion transactions per second (TPS) to accommodate the future rise of AI agents in digital commerce.
- Current blockchain systems lack the scalability required, operating significantly below this threshold, with leading networks like Internet Computer Protocol (ICP) and Solana achieving peak performances of approximately 25,621 TPS and 5,289 TPS, respectively.
- Stress tests during speculative trading revealed vulnerabilities in blockchain infrastructure, raising concerns about handling sustained AI-driven transaction flows.
The future of digital commerce may not be driven by humans clicking “buy now.” Instead, it could be powered by intelligent software quietly handling purchases, subscriptions, logistics, and payments in the background. That is the vision outlined by executives at Stripe, who argue that blockchains may eventually need to process up to one billion transactions per second (TPS) to support the rise of AI agents. In their latest annual letter, published publicly on X, CEO Patrick Collison and co-founder John Collison laid out a sweeping forecast: artificial intelligence agents are poised to transform how payments move across the internet. But there is a catch. Today’s blockchain systems, they argue, are nowhere near ready for that scale. At the heart of the debate is a single, urgent challenge: blockchain scalability for AI agents.
Stripe’s Billion-Transaction Prediction
Stripe has long been at the center of online financial infrastructure, powering payments for millions of businesses worldwide. When its founders speak about digital commerce, markets tend to listen. In their 2025 performance review and outlook letter, the Collison brothers painted a picture of a near future where AI agents will not just assist humans but act autonomously on their behalf. These agents could subscribe to services, negotiate pricing, purchase digital assets, reorder groceries, and manage software tools without manual oversight. If that happens at scale, the global transaction load would explode. According to Stripe’s leadership, blockchains might need to handle not just millions, but potentially one billion transactions per second. This projection underscores the importance of blockchain scalability for AI agents, as traditional throughput levels would be insufficient for a world where billions of autonomous programs transact continuously. Today, even the fastest networks operate far below that mark.
The Current State of Blockchain Throughput
Data from Chainspect shows that among major public blockchains, Internet Computer Protocol and Solana lead in real-world transaction speed.
- Internet Computer Protocol (ICP) processes roughly 1,196 TPS in typical conditions.
- Solana processes about 1,140 TPS on average.
At peak performance:
- ICP has reached approximately 25,621 TPS.
- Solana has climbed to around 5,289 TPS.
Theoretical limits are higher:
- ICP’s stated maximum capacity is about 209,708 TPS.
- Solana’s theoretical ceiling stands at 65,000 TPS.
Even at their maximum theoretical throughput, these networks remain far from the billion-TPS threshold envisioned by Stripe’s founders. This gap illustrates why blockchain scalability for AI agents is no longer a niche technical issue. It is becoming a foundational requirement for the next phase of internet evolution.
When Memecoins Reveal Structural Weakness
Stripe’s warning is not purely hypothetical. The company points to real-world stress tests that exposed vulnerabilities in blockchain infrastructure. During a memecoin trading surge last year on a major blockchain network, transaction congestion created widespread disruption. One user of Bridge, a payments product connected to blockchain rails, reportedly experienced payout delays exceeding 12 hours. At the same time, transaction fees skyrocketed—rising by more than 35 times their normal levels. These issues were triggered by speculative trading activity, not mass AI deployment. If a memecoin rush can create such severe strain, what happens when autonomous AI agents execute millions or billions of microtransactions every second? The lesson is clear: existing networks struggle under temporary demand spikes. Sustained AI-driven transaction flows would require orders-of-magnitude improvement. That reality puts blockchain scalability for AI agents at the center of long-term infrastructure planning.
AI Agents: Moving Beyond the Hype
The Stripe founders argue that AI commerce has moved beyond its early hype cycle. The industry is now entering a “build and test” phase, where companies focus on practical applications instead of futuristic promises. They describe five levels of AI agent capability:
1. Form Filling
The most basic level involves automating simple web tasks—completing checkout pages, submitting forms, and inputting user data.
2. Descriptive Search
Agents advance by understanding context. Instead of relying on keywords, they interpret full scenarios and retrieve relevant information. According to Stripe’s leadership, AI systems are close to mastering these first two levels at scale.
3. Persistence
At this stage, agents remember user preferences, financial details, and behavioral patterns over time. This continuity allows smoother and more personalized transactions.
4. Delegation
Here, agents act independently to complete complex tasks. They could manage recurring purchases, compare prices, negotiate service contracts, or rebalance digital portfolios.
5. Anticipation
The most advanced stage involves predictive behavior. Agents proactively suggest solutions, reorder essentials, or adjust schedules before users even ask. As AI moves through these five stages, transaction volumes could increase exponentially. Billions of agents interacting across open systems would generate a constant stream of economic activity. Without dramatic upgrades in blockchain scalability for AI agents, such a system could collapse under its own weight.
Why Open Systems Matter
Stripe’s founders compare this moment to the early days of the internet. In the 1990s, open protocols allowed websites, email systems, and payment networks to interoperate freely. That openness fueled rapid innovation and global adoption. AI agent commerce, they argue, depends on similar interoperability. Agents must move seamlessly across platforms, wallets, marketplaces, and services. Closed systems may restrict functionality. Open blockchains, by contrast, provide a neutral settlement layer accessible to anyone. However, openness alone is not enough. Speed, reliability, and cost efficiency are critical. If agents encounter slow confirmations or volatile transaction fees, automation breaks down. A machine cannot wait hours for settlement or tolerate unpredictable costs. This is why the conversation increasingly circles back to blockchain scalability for AI agents as a strategic imperative rather than a technical luxury.
Stripe’s projection that blockchains may need to process up to one billion transactions per second is bold, but it reflects a broader shift unfolding across the technology landscape. As AI agents advance through stages of persistence, delegation, and anticipation, they could transform from helpful assistants into autonomous economic participants. That transformation would generate unprecedented transaction volumes across open networks. Today’s leading blockchains, including Internet Computer Protocol and Solana, represent meaningful progress, yet they remain far from the scale envisioned by Stripe’s founders. The race is now on to close that gap. Whether through architectural innovation, layered solutions, or entirely new paradigms, the future of digital commerce may depend on achieving true blockchain scalability for AI agents.
