Global Households Added Record $40 Trillion in 2025 as AI-Linked Equities Drove 57% of Gains

Summary
$40 trillion in new household wealth lifted global net worth to a record $570 trillion in 2025, up 7.3% and pushing the world balance sheet to nearly $1.8 quadrillion, McKinsey said.
Only about 20% of that increase came from real capital formation, while equities generated 57% of new wealth and real estate 15%, marking a sharp break from 2000-2024 when property drove most gains.
U.S. stocks sat at the center of the surge: equity values reached 2.4 times corporate net assets in 2025, and just over half of S&P 500 market-cap growth since 2021 came from the AI-linked Magnificent Seven.
China showed the opposite imbalance, with balance-sheet growth driven by debt rather than equity multiples; corporate debt hit 80% of real assets and 1.7 times GDP as falling property values weighed on household wealth.
McKinsey said the gap between swelling asset values and the underlying economy could unwind through stronger productivity, higher inflation or asset-price corrections, or persist under stagnation-like conditions.

$40 Trillion Wealth Surge in 2025: AI-Driven Asset Boom, Paper Gains, and Global Inequality Risks
Overview
In 2025, global household wealth soared by $40 trillion, driven mainly by a surge in equity markets fueled by optimism around artificial intelligence. While the United States and other developed markets saw record highs in stocks, real estate cooled in major economies like China, shifting the main source of new wealth from property to equities. However, most of this wealth was paper gains, as asset values rose much faster than the real economy, making households vulnerable to market corrections. This rapid asset inflation widened inequality, making it harder for younger and lower-income people to enter the housing and asset markets.
