The HAR Index — Humans Above Replacement — is a framework for measuring how vulnerable a company’s workforce is to AI displacement. Think of it like WAR in baseball, but for entire organizations: how many of your employees are doing work that AI cannot yet replace?
The answer varies wildly across the Fortune 500. A company with 2 million retail workers faces a fundamentally different automation calculus than one with 160,000 engineers. Below, we explore the data — which sectors are most exposed, which companies have the largest labor costs at risk, and what the numbers actually mean for the future of work.

The $80 Billion in Exposed Labor
Across just these 15 companies, over $80 billion in annual labor costs sit in roles with meaningful automation exposure. That number is not a forecast of layoffs — it is a measure of where AI creates the most economic pressure to restructure.
The exposure looks different depending on the industry. Amazon’s $22 billion in exposed labor cost is concentrated in warehouse operations and logistics — roles that are being automated through robotics and AI-driven supply chain optimization. JPMorgan’s $6.8 billion sits in compliance, back-office processing, and data analysis — cognitive roles that LLMs are increasingly capable of handling. Walmart’s $16.6 billion spans checkout, inventory management, and administrative functions.
The pattern is clear: every sector has billions at stake, but the type of work exposed varies enormously. Retail faces physical automation. Finance faces cognitive automation. Healthcare faces administrative automation. The common thread is scale — the companies with the largest workforces have the most to gain or lose from how quickly they adapt.
Inside the Numbers: Walmart’s Workforce
To understand what a HAR score actually means, look at Walmart — the largest private employer in the world. Their 2.1 million employees span 22 occupational categories, each with different levels of AI exposure. Over half the workforce is in sales roles. Nearly 28% is in office and administrative positions. These two categories alone account for the vast majority of Walmart’s $16.6 billion in exposed labor costs.
Meanwhile, their computer and math roles — just 3.4% of headcount — face high theoretical exposure but command premium compensation that creates a natural buffer against displacement. The math is simple: it costs more to automate a $150K engineer than a $30K cashier, even if the technical feasibility is similar.
What This Means for Investors
The HAR Index reframes AI disruption from a technology question to a labor economics question. The relevant variable is not which companies use AI — it is which companies have the largest gap between their current labor costs and what those roles will cost once AI is widely adopted.
For a company like Amazon, $22 billion in exposed labor is not a liability — it is optionality. If automation captures even 20% of that over the next decade, it represents a massive margin expansion opportunity. The same logic applies across the F500: exposed labor cost is a leading indicator of where AI-driven restructuring will create the most economic value.
The companies that move early will compound the advantage. The ones that wait will face the same pressure as disruption rather than opportunity.
