Bain's new estimate puts about three quarters of the profit AI will shift by 2035 in innovation and market share, so a manufacturer should check how many of its funded AI initiatives go after either one.
In a brief published on September 8, 2026, Bain estimates that AI puts $4.7 trillion in profits at stake between 2025 and 2035, from scoring 92 sectors. It splits the total three ways: $1.1 trillion from productivity gains, meaning existing work done cheaper, faster or at larger scale; $2.2 trillion from innovation, the new products and services AI makes possible; and $1.3 trillion from market share moving between competitors. Bain's figures are rounded, so the three parts add to $4.6 trillion. Part of the innovation figure is the technology foundation of chips, data centers and AI models, which Bain says "grows with every adopter", and most manufacturers will buy those rather than sell them.
Bain expects much of AI's productivity gain to reach customers as cheaper or better products, so its $1.1 trillion counts only the gains companies keep. On market share, the brief tells CEOs in many sectors that the fight is with competitors they already know more than with a new entrant: "You're more likely to lose share to the competitor that makes the best use of AI."
Bain names industrial manufacturing among the sectors the Internet left alone that AI will now structurally transform, and it sorts the 92 sectors into four clusters. Machinery sits in the one it calls rewired, with $1.5 trillion, where Bain sees no predetermined winners in sectors that include machinery, automotive OEM and automobile components. Where AI leaves a sector's rules intact, in the cluster Bain calls augmentation, with $1.3 trillion, it expects companies that move slowly on productivity to find that competitors have captured the margins first.
Reported results so far lean toward productivity, the smallest of the three parts: in a Bain and StepStone survey of 103 private equity investment and investor relations professionals, mostly in North America and Europe, run from December 2025 to January 2026 and published in March, AI outcomes reported in portfolio companies skew toward cost savings and efficiency more than revenue growth.
A CEO can hold the current plan against Bain's split using the list of AI initiatives the company has funded. Mark each one by the part it goes after: existing work done cheaper, something the company can sell that it could not sell before, or share taken from a competitor the team can name. For a maker of packaging machinery, matching supplier invoices and drafting service reports sit in the first part; a paid service that reads sensor data from machines already running at customers' plants and warns before one fails sits in the second; a quoting tool that configures and prices a custom machine within days of the request sits in the third, aimed at the competitor that wins those bids today.
By the next quarterly review, each initiative in the second or third part should carry the revenue number it is meant to move and the person who owns that number, the way each cost initiative carries its saving.
Bain sizes the whole shift at about a fifth of the global corporate profits it projects for 2035.
