Jack Dorsey of Block says AI could handle 40% of your work.

Jack Dorsey pointed to artificial intelligence as the main reason for eliminating 40 % of his firm’s staff, yet a sluggish cryptocurrency market, excess headcount and a falling share price likely also played a part.

The fintech firm Block disclosed last week that it would dismiss 4,000 of its 10,000 employees. In a letter to investors, Dorsey wrote that recent AI progress “has altered what it means to build and run a company.”

“We’re already seeing it inside the organization. A much smaller crew, equipped with the tools we’re developing, can accomplish more and do it better. And the capabilities of intelligence tools are accelerating every week,” he added, noting that Block’s operations remained solid and that the reductions were not a cost‑cutting measure.

Can AI replace 40 % of a business’s workforce? It might, but other pressures loom over Dorsey’s enterprise.

For most of the past decade the CEO and Block have pursued a full‑scale commitment to crypto, rebranding from Square to Block in 2021 to invoke “blockchain.” At that point Dorsey steered the company toward blockchain and Bitcoin while continuing to grow the Cash App. In 2024 the firm announced it would allocate 10 % of its gross profit from Bitcoin products to buying Bitcoin itself.

A firm whose strategy centers on digital currencies may have motives beyond AI for trimming staff. Public filings suggest Block holds roughly 8,500 BTC. Bitcoin has shed almost a quarter of its value since the start of the year, and the wider crypto market has shown similarly weak performance. Prior to Dorsey’s announcement, Block’s shares had fallen about 35 % from a peak in October.

The blend of a crypto downturn and a depressed stock price offers a more immediate, less speculative explanation for the layoffs. The announcement did trigger a short‑term market reaction: Block’s share price jumped roughly 20 % and held that gain in the following days.

Tech‑sector layoff news has produced mixed market responses in recent months.

Ahead of two quarterly earnings releases—in October 2025 and January 2026—Amazon revealed plans to cut 14,000 and 16,000 jobs, respectively. After the 2025 filing, the retailer’s stock surged, while the January 2026 disclosure sent the price lower as Amazon grappled with soaring data‑center expenses, a cost pressure Block does not face.

Salesforce eliminated 4,000 customer‑support positions last year after CEO Marc Benioff said AI could handle about half of client interactions. The move coincided with a decline in the company’s share price, as investors view the software segment, which includes Block, as especially exposed to automation.

A November 2025 Goldman Sachs study found that firms announcing layoffs generally underperformed the broader market, particularly when the cuts were framed as restructuring in response to automation and technology.
