Jack Dorsey fires 4,000 from Block, but shares jump 20%. Does the stock market prefer AI over humans?

The parent of Square and Cash App's fourth-quarter gross profit rose 24% year-on-year, reflecting strong demand for its payments products and services. Block expects to incur about $450 million to $500 million in restructuring charges tied to the layoffs.

In a letter to shareholders, Chief Executive Jack Dorsey said intelligence tools have changed what it means to build and run a company, adding that a significantly smaller team, using the tools we’re building, can do more and do it better. He argued that most companies are late in recognising how AI can reshape operating models.


The reaction in the stock market raises a broader question about whether the market does not care about the human cost.

Historically, markets are not designed to price social impact directly. Stock prices usually reflect the expected future earnings and cash flows predictability. If investors believe job cuts will structurally lower costs, lift margins and accelerate productivity, especially when paired with strong revenue or profit growth, they typically reward the stock.

This is exactly what happened in this case. Investors saw many positives in the announcement that shook the tech world and beyond.

First, gross profit growth of high double-digits suggested the core payments business remained resilient. Further, Dorsey signalled that layoffs are a structural cost reset, not a temporary trimming. And finally, the tech world and with it investors are slowly coming to terms that a pivot to AI is inevitable, and the costs, whether it be humans or otherwise, will be there.

Dorsey's unusually direct attribution of layoffs to AI may also have sharpened the narrative. Stephen Innes of SPI Asset Management, while speaking to Reuters, described the move as a "public case study" of a CEO stating that intelligence tools have altered what it means to run a company.

While many firms have announced layoffs in recent months, few have so openly connected them to AI-driven productivity gains.

For investors, cost-cutting is often viewed through the lens of operating leverage. If a company can maintain or grow revenue with a smaller workforce, margins expand. Higher margins increase earnings per share, even after accounting for one-time restructuring charges. In discounted cash flow terms, that improves the present value of future profits.

There is also a broader macro narrative at play. Markets are increasingly pricing in a world where AI enhances productivity across sectors. Companies that proactively restructure around AI are often perceived as better positioned than those that delay.

That does not mean social consequences are irrelevant. Layoffs can dampen morale, reduce institutional knowledge and carry reputational risk. Over time, if productivity gains fail to materialise or innovation suffers, the market can reverse its view. But in the short term, especially during earnings season, stronger profit growth combined with credible cost discipline tends to dominate investor thinking.
