Consulting's billable hour dies twice: once to AI, once to infrastructure
Deloitte's 2035 timeline for pricing model obsolescence collides with McKinsey's infrastructure buildout thesis—forcing firms to price gigawatts delivered, not hours worked.
year Deloitte projects billable hour model shrinks to revenue sliver
Deloitte's internal projection that AI agents will compress hourly billing to a sliver of revenue by 2035 forces every firm to confront pricing model obsolescence now, while McKinsey's coordinated release of over a dozen sector analyses maps trillion-dollar infrastructure demand requiring outcome-based pricing for commissioning timelines and gigawatts delivered.
One pattern. Trace it.

Watch three indicators over the next 90 days
First, billing model shifts: track whether any Big Four or MBB firm formally announces outcome-based or subscription pricing for a major practice area — Deloitte's internal messaging suggests announcements could come as early as Q4 2026. Second, infrastructure advisory hiring: monitor LinkedIn and industry job boards for senior hires in nuclear energy, data center operations, and semiconductor supply chain at major consulting firms — a spike would confirm the infrastructure pivot thesis.
- Shift
For the first time a Big Four firm declares its own revenue model obsolete within a decade
- Shift
Infrastructure consulting now requires engineers and permitting specialists over strategy generalists
- Shift
Clients demand fixed-price execution for multi-billion-dollar buildouts while AI automates hourly advisory work
“What percentage of our current book is billed hourly, and which three clients could we pilot outcome-based pricing with by Q3?”
Ask your consulting partners this week what percentage of their proposals are outcome-based versus hourly, and whether they can price your next infrastructure engagement on delivery milestones.
