Block AI layoffs cut 4,000 jobs, nearly half its staff
The Block AI layoffs, announced by Jack Dorsey in February 2026, cut 4,000 jobs and took the payments company behind Square and Cash App from over 10,000 employees to just under 6,000. Dorsey said intelligence tools, paired with smaller and flatter teams, let the company do more. For other employers, Block is now a public test of whether AI can carry the work of a much smaller staff while the business keeps growing.
Why Block decided to cut nearly half its workforce
Block cut its staff because its chief executive believes AI tools let a much smaller company do the same work. Jack Dorsey, Block's founder, announced on a Thursday in February 2026 that the company would lay off 4,000 employees, taking its workforce from over 10,000 to just under 6,000.
He did not present it as a rescue. "We're not making this decision because we're in trouble," Dorsey wrote in a post on X. "Our business is strong." He also said the cuts were in part a reaction to overhiring during COVID.
Block, founded in 2009 and based in San Francisco, is the parent company of the payment platforms Square and Cash App. It operates in the United States, Canada, parts of Europe, Australia and Japan.
What Block says AI tools changed inside the company
Dorsey tied the cuts directly to the company's use of AI. In his X post, he wrote that the intelligence tools Block is creating and using, paired with smaller and flatter teams, are enabling a new way of working that changes what it means to build and run a company.
"A significantly smaller team, using the tools we're building, can do more and do it better." — Jack Dorsey, in his letter to Block shareholders
In the same letter, Dorsey summed up the thesis as simple: intelligence tools have changed what it means to build and run a company. Block did not say which teams or countries the cuts would hit, and it was unclear which employees would be laid off where. Dorsey said terms for employees overseas might differ.
How Block plans to work with smaller, flatter teams
The operating model Dorsey describes has two parts: the tools Block builds and uses, and teams with fewer layers. He framed the timing as a choice. "I'd rather get there honestly and on our own terms than be forced into it reactively," he wrote.
He also predicted that others would follow. "Within the next year, I believe the majority of companies will reach the same conclusion and make similar structural changes," he wrote in the shareholder letter.
What Block's results and stock did after the announcement
The figures around the decision are financial, and Block reported them as the business it already had, not as savings from the cuts. Block reported fourth-quarter gross profit of $2.87 billion, up 24% year over year. Dorsey said the customer base is expanding and profitability is improving, which he attributes to AI; that is the company's own claim.
Investors reacted quickly. Block shares gained 5% on the Thursday to $54.53 before the earnings report and shot up to nearly $69 in after-hours trading. On Friday, February 27, 2026, shares rose more than 20% in premarket trading, according to the Associated Press, and Fortune reported the stock up nearly 18% that day.
What the Block AI layoffs mean for other employers
For other companies, Block is a public test of whether AI can carry the work of a much smaller staff. Stephen Innes of SPI Asset Management called it a public case study in which the CEO explicitly ties the cuts to intelligence tools. Other large employers have announced cuts and downplayed the AI link; Block did not.
The wider evidence is mixed. A 2025 McKinsey report found that most firms are still experimenting with AI and nearly two-thirds have yet to scale it. A survey of 6,000 CEOs and executives by the National Bureau of Economic Research found AI has yet to show a major impact on their operations. An Oxford Economics report released in January found that many layoffs CEOs called AI-related were actually the result of past overhiring.
Others have moved in the same direction. Salesforce chief executive Marc Benioff reduced the company's customer support workforce by 4,000 as AI took over some work.

How we would build it
Block's bet is that the work did not shrink, the number of people needed to do it did. A company testing the same idea should first measure that, team by team, before it changes headcount. We would start with the work that has clear inputs and outputs: code changes, support tickets, compliance reviews, merchant onboarding. For each one, we would record how much an AI tool drafts, how much a person rewrites, and how often the result goes back for a fix.
The system behind a smaller team needs more than chat tools. It needs access to the company's own code, documents and ticket history, permissions that match each person's role, and a log of what each tool did. People still own the decisions. In a payments company, a reviewer would sign off on anything that touches customer money, fraud rules or regulators.
Where it breaks is quiet: fewer people means fewer eyes on edge cases, and quality slips slowly. The one metric we would watch is the rate of errors that reach customers per unit of work shipped, tracked before and after the cut. Next we would build the review tooling itself, so the remaining staff spend their time checking the hard cases instead of the easy ones.
