What is IBM's COBOL business?: IBM is the primary commercial servicer of COBOL, the programming language running the core systems of most large banks and US government agencies. This creates a durable maintenance revenue stream largely insulated from AI disruption.

Background

IBM (International Business Machines) was founded in 1911 and is headquartered in Armonk, New York. One of the oldest and largest technology companies in the world, IBM built the mainframe computing industry, pioneered enterprise software, and later refashioned itself around consulting and hybrid cloud. It remains one of the leading players in enterprise AI infrastructure and operates through two main divisions: Software (including its Red Hat acquisition) and Consulting, the latter generating approximately .27 billion per quarter. IBM employs around 280,000 people globally.

In Q1 2026 IBM reported revenue of .92 billion, beating the .62bn consensus. But shares fell 6-8% after-hours as investors focused on the consulting division's slight miss — $5.27bn against a $5.28bn estimate — reading AI productivity as a structural headwind to professional services billing. Simultaneously, IBM disclosed its internal AI coding tool watsonx Code Assistant, nicknamed 'Bob', was delivering 45% average developer productivity gains, contributing to $4.5 billion in cumulative productivity savings since 2023, with a further $1 billion expected in 2026. Generative AI now accounts for 30% of IBM's consulting backlog.

IBM's situation exemplifies the central tension in the AI jobs story: the same productivity tool that drives the revenue beat creates investor concern that consulting revenues will structurally compress. The company's COBOL maintenance moat — IBM remains the primary servicer of the mainframe code running global banking and government systems — provides a significant hedge, but the consulting miss has intensified pressure on how IBM prices AI-delivered work.

How the World Sees Them

Labour

IBM has not announced major layoffs tied to Bob's adoption, but the productivity figures imply fewer billable hours are required for the same output, raising structural employment concerns.

Investors

The Q1 miss on consulting despite an overall revenue beat confirmed fears that AI productivity will compress IBM's billable services over time; shares sold off 6-8% after-hours.

US government

IBM's COBOL maintenance role in federal and banking systems is treated as critical national infrastructure, insulating a portion of its revenue from AI disruption.

Enterprise clients

Clients using IBM's Bob tool report substantial productivity gains; the question is whether those savings accrue to clients through lower contracts or to IBM through higher margins.
