Block Cuts 40% of Workforce as Jack Dorsey Bets Big on AI

Jack Dorsey's Block, the parent company of Square and Cash App, is cutting approximately 4,000 employees — roughly 40% of its workforce — in what may be the most aggressive AI-driven restructuring in corporate history. The announcement, made via a shareholder letter on February 26, sent Block's stock soaring as much as 24% in after-hours trading.

Key Highlights

• Block is reducing its workforce from over 10,000 to under 6,000 employees
• The company's internal AI agent, Goose, is cited as the primary enabler of the cuts
• Engineers using Goose are shipping approximately 40% more code per person than six months ago
• Block shares surged from $54.53 to nearly $69 after-hours, adding roughly $8 billion in market cap
• Dorsey predicts most companies will make similar cuts within the next year

"Intelligence Tools Have Changed Everything"

In his shareholder letter, Dorsey was blunt about the reasoning: "Intelligence tools have changed what it means to build and run a company." He argued that "a significantly smaller team, using the tools we're building, can do more and do it better. And intelligence tool capabilities are compounding faster every week."

The decision centers on Goose, Block's open-source AI agent platform that started as a small engineering experiment roughly two years ago. Built on Anthropic's Model Context Protocol (MCP), Goose can write and execute code, debug failures, orchestrate workflows, and interact with external APIs autonomously. The tool has expanded beyond engineering to nearly every department at Block, reportedly saving employees 8 to 10 hours per week.

Market Reacts with Enthusiasm

Wall Street responded decisively. Block shares jumped over 20% in premarket trading, reflecting investor confidence in the AI-driven efficiency narrative. The roughly $8 billion increase in market cap following the announcement underscores how the market is rewarding companies that aggressively adopt AI to cut costs.

A Warning for the Industry

Dorsey's most provocative statement may be his prediction about the broader industry. "I think most companies are late," he wrote. "Within the next year, I believe the majority of companies will reach the same conclusion and make similar structural changes."

The numbers support a growing trend. In 2025 alone, companies attributed 55,000 job cuts directly to AI adoption — a sharp rise from previous years. Early 2026 has already seen over 22,000 AI-related reductions across the industry, with Block's cuts representing the single largest AI-attributed layoff to date.

What This Means

Block's move represents a watershed moment in the AI-and-jobs debate. While previous layoffs cited AI as a contributing factor, Dorsey's letter explicitly frames artificial intelligence as the primary driver — not a recession, not declining revenue, but a fundamental belief that AI tools have crossed a productivity threshold that makes large workforces unnecessary.

For the 4,000 affected employees, the implications are immediate and personal. For the broader tech industry and beyond, Dorsey's prediction that most companies will follow within a year raises urgent questions about workforce readiness, retraining programs, and the pace at which AI is reshaping the employment landscape.
