Analysis

The state of play: AI across sectors in 2026

Adoption is no longer the story — impact is. Individual uptake has gone near-universal wherever people work with information: 81% of US physicians now use AI professionally, double the 38% of 2023 (AMA, 2026), and 92% of UK undergraduates use generative AI, up from 66% two years earlier (HEPI, 2025). In classrooms, 32% of US teachers now use AI weekly, reclaiming roughly six weeks a year (Gallup, 2025).

Spending draws a sharper line between sectors. IDC puts software and information services, banking, and retail at the top of AI investment, with financial services outlaying about $3,200 per employee — roughly 2.6x the cross-industry average. Yet dollars do not guarantee returns: McKinsey finds 88% of organizations now use AI while 81% report no meaningful bottom-line impact, and only about 6% of top performers attribute more than 5% of EBIT to it.

The spread between leaders and laggards looks organizational, not technical — the firms capturing value redesign their workflows around AI rather than bolt it onto old ones.

Key takeaways
  • ▪Usage is near-universal in knowledge work — 81% of US physicians (AMA) and 92% of UK undergraduates (HEPI).
  • ▪Financial services, software, and retail lead AI spend (IDC); finance outspends the cross-industry average ~2.6x per employee.
  • ▪Adoption and impact diverge: 88% of firms use AI but 81% see no bottom-line gain; just ~6% are true value-capturing leaders (McKinsey).
