Jack Dorsey Cuts Block Workforce by 40% to Embrace AI Efficiency

Block CEO **Jack Dorsey** has slashed the company's workforce by nearly half, reducing headcount from over 10,000 to just under 6,000 employees, in a bold move tied directly to artificial intelligence adoption. This decision, announced on Thursday, affects more than 4,000 workers at the fintech giant behind Square and Cash App, despite a strong 2025 performance. Dorsey's public 600-word memo on X emphasizes that intelligence tools are transforming how companies operate, enabling smaller teams to achieve more with greater effectiveness.

This article is for tech executives, investors, and fintech professionals grappling with AI's impact on workforce strategy, helping them understand how to balance efficiency gains with morale amid rapid technological shifts. Dorsey argues that gradual cuts over months or years would erode trust and focus, opting instead for immediate action to align with AI realities. He commits to a human approach, promising not to abruptly remove laid-off employees from Slack and email, and plans a live video session to express gratitude for their contributions.

Dorsey positions AI at the core of Block's future operations, stating that the tools the company is developing allow a significantly smaller, flatter team to outperform larger ones. In his shareholder letter, he notes internal evidence of this shift, predicting that most companies will follow suit within the next year. Block's fourth-quarter gross profit rose 24% year-over-year, with customer base expansion and improving profitability credited to AI implementation. Investors reacted enthusiastically, driving Block's stock up nearly 18% on Friday after an initial 5% gain Thursday, reaching nearly $69 in after-hours trading.

Former employees report mixed experiences with AI integration. Some data analysts and engineers used AI tools daily, noting celebratory internal demos and rising productivity expectations, though not anticipating such swift cuts. One engineer saw their team shrink from eight to one member, while performance reviews were accelerated, heightening office tension. Dorsey hosted a 'gratitude' video call shortly after the announcement, wearing a 'love' baseball cap amid emoji reactions ranging from thumbs-down to thinking faces.

Dorsey's explicit linking of layoffs to AI sets Block apart from peers who downplay the connection, often citing COVID-era overhiring. Leaders like Amazon's Andy Jassy and Salesforce's Marc Benioff have warned of reduced headcount needs due to AI automation, echoing warnings from Microsoft AI chief Mustafa Suleyman about white-collar job displacement within 18 months. An Oxford Economics report suggests many claimed AI layoffs stem from overhiring corrections, yet Block's scale marks a significant S&P 500 case study.

Layoffs support for affected workers includes consultations for overseas staff, though specifics on roles and locations remain undisclosed. This follows earlier waves of cuts at Block this month.

Dorsey's unapologetic AI pivot positions Block as a vanguard in fintech restructuring, potentially accelerating industry-wide adoption of leaner, intelligence-augmented teams. While short-term stock gains validate investor confidence, long-term success hinges on retaining top talent and mitigating morale hits from 'chainsaw' cuts. As AI tools mature, expect more CEOs to cite them explicitly, reshaping white-collar work but risking a broader jobs 'apocalypse' if productivity doesn't scale proportionally.
