Recently, my attention has been drawn to what is actually happening with Block. The company is shrinking drastically, cutting employees from over 10,000 at the pandemic's peak to around 6,000 now, almost back to their 2019 size when they only had 3,800 people. At first glance, it looks like ordinary efficiency, especially with Jack Dorsey emphasizing how AI enables smaller teams to work faster.

But there is a much deeper story here, and I believe this is what needs to be watched.

Block is built on a traditional payment model, where they take a percentage of each merchant transaction. The 2-3% fee has been their growth engine for years. However, stablecoins are beginning to fundamentally change this equation. Unlike before, when stablecoins were seen only as crypto trading instruments, now with clearer regulation through initiatives like the GENIUS Act and IPO Circle, these tokens are starting to look like serious payment alternatives.

The problem goes even deeper with the emergence of agentic shopping. Imagine an autonomous AI assistant that compares prices, optimizes payment routes, and executes transactions on behalf of the user. In this scenario, transactions are completed in seconds with nearly zero fees. When AI-driven machines can handle payments for a few cents instead of full percentage, the structural margins of the traditional model start to be squeezed.

So this staff reduction may not just be a response to pandemic overhiring. It’s a more fundamental adjustment to the reality that the payments landscape is changing. Block is a major player in the old ecosystem, and they are recalibrating for a world where cost compression is structural, not just a temporary competitive pressure.

Investors clearly see this as positive, pushing the stock up more than 23% in after-hours trading. Still, the stock is about 80% below its pandemic peak, indicating that market expectations have drastically adjusted since those aggressive hiring days.

There’s an interesting comment from Ben Carlson at Ritholtz Wealth Management that captures this dilemma: maybe this is a sign that AI will destroy everything, or maybe they just overhired and AI is an easy excuse. But I think there’s something more fundamental happening here about how payments will work in the future.
