AI to obesity drugs: McKinsey identifies 18 sectors for next wave of global growth

Where can global growth come from in the next 15 years? This is a crucial question not only for industrialists and investors, who would directly channelise their money and skill pool towards such sectors but also for governments and economic policymakers who would try to incentivise the proliferation of these sectors in the economy.

According to McKinsey, e-commerce could generate a revenue of $14,000-20,000 billion by 2040.

The 2024 study

McKinsey had done such a study in 2024 too, when it detected 12 industries on the basis of high growth and dynamism, which included cloud services, e-commerce, biopharmaceuticals and electric vehicles. "This dynamic dozen more than doubled their revenue share between 2005 and 2023 and grew their market capitalization by 14 percent per year, compared with 5 percent for the 45 other (non-arena) industries analyzed. The 12 arenas saw more new entrants, much higher R&D investment, and greater economic profits, too. At the root of their growing success, we found an "arena-creation potion” with three main ingredients: a technology or business model breakthrough, an escalatory race with ever-larger investments, and an addressable market that enables global scale and is large, growing, or both," McKinsey stated in its report.
