What prompted Block’s Jack Dorsey to reduce nearly half of his workforce?

Jack Dorsey, CEO of Block, recently attributed the significant decision to cut 40% of his company’s workforce to advancements in AI. However, it’s essential to consider additional factors that may have influenced this move, including a struggling crypto market, potential overstaffing issues, and a dwindling stock price.

In a surprising announcement, Block revealed plans to lay off approximately 4,000 of its 10,000 employees. In his letter to shareholders, Dorsey remarked that the evolution of AI “has redefined what it means to build and operate a company.”

He elaborated, stating, “We’re already experiencing the benefits internally. A notably smaller team can leverage the tools we’re developing to achieve greater outcomes with improved efficiency. Moreover, the capabilities of intelligence tools are advancing at an unprecedented pace.” While Dorsey emphasized that Block remains on solid footing and characterized the layoffs as a strategic move rather than a cost-cutting measure, some skepticism lingers over whether AI can truly manage 40% of a business.

Dorsey’s commitment to cryptocurrency is evident, as he has favored this direction for nearly a decade, culminating in the company’s rebranding from Square to Block in 2021—a name inspired by “blockchain.” At that time, he pushed the business to integrate blockchain technologies and Bitcoin, alongside the thriving Cash App. Notably, in 2024, Block announced plans to reinvest 10% of its gross profit from Bitcoin products directly into Bitcoin purchases, highlighting its dedication to the digital currency.

However, a business strategy heavily reliant on cryptocurrency brings challenges, prompting Dorsey to consider factors beyond the allure of AI when it comes to staff reductions. As indicated by various estimates, Block’s current Bitcoin holdings stand at approximately 8,500 BTC. Yet, the value of Bitcoin has declined significantly since the year’s onset, losing about a quarter of its worth. The wider cryptocurrency market has mirrored this disappointing trend. Prior to Dorsey’s layoffs announcement, Block stock had already suffered a 35% drop since peaking in October.

The convergence of a bearish crypto market and a falling stock price provides a tangible rationale for Dorsey’s layoff decision, moving beyond the narrative focused solely on AI integration. Following the layoff announcement, a notable immediate result was seen: Block’s stock surged by 20%, and this growth was largely maintained in the days following the announcement.

Stock market reactions to layoffs in the tech sector have been unpredictable in recent months. For instance, just prior to two significant quarterly earnings reports in October 2025 and January 2026, Amazon cut 14,000 and 16,000 positions, respectively. Amazon’s stock price experienced a noticeable increase after the October announcement but fell following the January declaration, largely due to skyrocketing operational costs linked to datacenter expenditures — an area where Block does not face similar challenges.

In contrast, Salesforce laid off 4,000 customer support employees last year, with CEO Marc Benioff suggesting that AI can now manage approximately 50% of customer interactions. Yet, this resulted in a drop in Salesforce’s stock price, exemplifying concerns about the software sector’s vulnerability to potential disruptions. A study conducted by Goldman Sachs in November 2025 revealed that companies announcing layoffs consistently underperformed in the market. Moreover, those citing restructuring linked to automation and technology advances lagged significantly.

A former business leader at Block shared a compelling blog post, highlighting the issue of overstaffing, particularly outside of the company’s “bitcoin hardware team.” He referred to a period characterized as a “bloated headcount era” that began in 2020 when interest rates in the United States were exceptionally low.

Dorsey has a history of overstaffing within his companies. Although he acknowledged past overhirings, he defended the current workforce adjustments as unrelated to that issue, claiming that staffing matters had been addressed back in 2024.

The effectiveness of Block’s operations following these extensive layoffs will shed light on the potential capabilities of AI in minimizing reliance on human labor. Business leaders across the United States are setting increasingly ambitious productivity targets driven by AI’s potential. In particular, pressure is mounting on software engineers, as their tasks can be efficiently managed, at least partially, by AI-powered coding models. This has led many startup founders to exhaust themselves to keep pace with competitors.

However, the situation is not straightforward. Evidence suggests that AI may currently be adding to workloads rather than alleviating them for numerous employees. A recent Harvard study evaluating a 200-employee tech firm found that “AI tools didn’t reduce work; they consistently intensified it.” As a result, those remaining at Block may find themselves under similar pressures, balancing increased expectations with fewer resources.
