PwC's 2026 AI Performance Study, based on 1,217 senior executives across 25 sectors, finds the top-performing 20% of organizations generate 7.2× more AI-driven revenue and efficiency gains than the average. The differentiator is strategic rather than technological: leaders use AI to pursue new revenue lines and cross-sector expansion — "industry convergence" — rather than confining it to cost reduction in existing operations. AI leaders are also nearly twice as likely to run fully autonomous decision-making workflows and are increasing human-free decisions at 2.8× the rate of peers.
