Jack Dorsey announced Thursday that Block — the company behind Square, Cash App, and Afterpay — is cutting more than 4,000 employees, nearly half its workforce. Wall Street immediately responded and the stock jumped almost 24% in after-hours trading. Within minutes, the market had added roughly $8 billion to Block’s valuation — if you do the math, and the math is the real story here — that’s about $2 million per eliminated job.
What Dorsey Actually Said
Dorsey framed the cuts as an AI-driven structural shift, not a financial emergency. Block’s business is growing, he wrote in a letter to shareholders — gross profit is up, customers are increasing, profitability is improving. But “intelligence tools,” paired with “smaller and flatter teams,” have fundamentally changed what it means to run a company.
He had two options: cut gradually over months or years, or act decisively now. He chose the latter. “Repeated rounds of cuts are destructive to morale,” he wrote. Then the kicker — a prediction directed at every CEO reading along: “Within the next year, I believe the majority of companies will reach the same conclusion.”
This isn’t coming from nowhere. Block has been building its own open-source AI agent called Goose since early 2025. The tool — which connects to any large language model and automates everything from code generation to data analysis — is already used by 60% of Block’s workforce weekly. Block’s CTO told Sequoia last year that Goose saves engineers 8–10 hours a week and is on track to eliminate 25% of manual hours Company-wide. Yes, 25%.
In other words, and the sequence matters — Block built the tool, measured the gains, and then cut accordingly.
The Incentive Machine
Here’s what makes this moment anything but anecdotal: Wall Street’s reaction
creates a powerful feedback loop.
This almost looks like an instruction manual: a CEO tells the market “we’re cutting 40% of our workforce because AI makes it possible” and the stock immediately jumps 25%. Every board in Silicon Valley (and beyond) is now staring at that chart. The message is unmistakable: the market will pay a premium for companies that convert AI capability into headcount reduction.
Block isn’t even the first. Klarna shrunk from 7,000 employees to about 3,000 over roughly four years, largely through AI-driven attrition. Salesforce cut 4,000 support roles after its CEO said AI handles half
the company’s work. Amazon, Microsoft, Chegg, Duolingo — the list keeps growing. Challenger, Gray & Christmas tracked roughly 55,000 job cuts directly attributed to AI in 2025 alone.
But none of those moves got a 25% same-day stock bump. Block did — and the scale of the reward will not go unnoticed.
The Uncomfortable Question
There’s a legitimate debate about how much of this is real and how much is what skeptics call “AI-washing” — blaming technology for cuts that are actually driven by bloated pandemic-era headcount and old-fashioned cost pressure. Block more than doubled its workforce between 2019 and its peak, from under 4,000 to over 10,000. Its stock, meanwhile, has fallen more than 75% from its 2021 high of nearly $282. A Wharton professor pointed out that it’s hard to imagine firm-wide 50% efficiency gains from tools this new.
Dorsey himself acknowledged the Musk parallel — and it’s worth remembering that Musk’s 50% cut at Twitter in 2022 was the move that rewrote the rules for how far a CEO could go in a single stroke. Dorsey watched that experiment unfold from an unusually close distance, given their intertwined history.
But what’s different now is that Dorsey has receipts. Block built Goose, measured the productivity gains, open-sourced the tool, and restructured the organization around it before pulling the trigger. Whether you agree with the decision, the process was more methodical than a vibes-based bet on “AI will figure it out.”
What This Signals
The real shift isn’t about Block or Dorsey. It’s about what happens when capital markets start explicitly pricing in AI-driven labor efficiency — when the “AI dividend” becomes a line item investors expect, rather than a theoretical upside buried in an earnings call.
My bet is that Dorsey’s prediction is directionally right, even if the timeline is aggressive. Not every company will cut this deeply, and many that try will discover (as Klarna did) that AI can’t yet replace the judgment, empathy, and context that humans bring to complex work. But the incentive structure is now locked in. Markets reward the cut. Boards notice. CEOs act.
For operators and investors, three things to watch: First, which companies have actually built internal AI tools (like Goose) versus which are using “AI” as cover for overdue restructuring — the distinction matters enormously for long-term execution. Second, whether the productivity gains hold over the next 2–3 quarters, or whether Block quietly rehires (as Klarna partially did). And third, the geopolitical gap. Dorsey executed this restructuring in a single day. In the EU, labor laws would require months of works council consultations before a single employee could be let go. If American companies can convert AI gains into radical headcount reductions overnight while European competitors are still filing paperwork, the valuation gap between US tech and the rest of the world isn’t going to close. It’s going to become a canyon.
This may be the most underpriced consequence of the AI shift: not which companies adopt AI fastest, but which legal systems allow companies to act on it.
The price tag is now public. The question isn’t just who moves next — it’s who’s allowed to.
