NEW YORK — David Kelly, chief global strategist at JPMorgan Asset Management, calculated on August 10, 2026, that the market value of all U.S. corporate equity is over 400% of GDP. This valuation level represents a significant increase from historical norms and signals historically high market conditions.

The ratio of U.S. corporate equity to GDP stood at 244% just before the pandemic, meaning the current figure marks a substantial rise from pre-pandemic levels. The metric was 204% at the peak of the 2000 dotcom bubble and 74% before the 1987 stock market crash, indicating a significant increase from both historical benchmarks.

The Buffett Indicator, which measures the ratio of publicly listed U.S. companies to GDP, is above 200%. Investor Warren Buffett and Carol Loomis described this metric as "probably the best single measure of where valuations stand at any given moment" in a 2001 Fortune article.

Market performance in 2026 has contributed to these elevated levels, with the S&P 500 up more than 13% year to date. Second-quarter earnings for two large technology companies included $150 billion of unrealized capital gains, which boosted pro forma earnings per share by 50% year over year. After excluding these unrealized capital gains, earnings growth was approximately 20%.

Kelly noted that corporate values are tied to broader economic activity. "In the end, the value of American corporations depends, to a large extent, on the work and spending of the American people," he stated.

Spending data from July 2026 shows varied trends across income brackets. The Bank of America Institute reported a 5.4% increase in spending among lower-income households and a 4.9% increase among middle-income households. The top 5% of earners continue to support outsized spending growth due to strong balance sheets and rising asset prices.

U.S. Treasury Secretary Scott Bessent cited 5.5% wage gains for the bottom quartile of earners in an August 2026 interview. He stated, "I got sick of hearing about this K-shaped economy," and added, "we’re seeing more of a C economy where the lower end of wage earners are finally calling it back."

Kelly expects the Federal Reserve to hold interest rates steady as inflation drifts down toward the central bank’s 2% target. He projects GDP growth to average about 2% in 2027 and advised investors to diversify away from a concentrated bet on AI stocks.

The rise in corporate equity value relative to GDP reflects a combination of strong market performance, elevated asset prices, and moderate economic growth. While equity values have surged, GDP growth has remained within a stable range, contributing to the expansion of the ratio. Analysts continue to monitor the sustainability of these valuations amid shifting monetary policy and global economic conditions.

Kelly emphasized that while current market levels are high, they are supported in part by real economic activity and consumer spending trends. He cautioned, however, that prolonged valuations at such levels could pose risks in the event of an economic downturn or a shift in investor sentiment.

Historical comparisons show that periods of high equity-to-GDP ratios have often preceded market corrections, though the timing and magnitude of such adjustments are difficult to predict. The current environment, marked by technological innovation and strong corporate earnings, differs in key respects from past high-valuation periods.

Investors are advised to maintain balanced portfolios and consider long-term fundamentals when assessing market conditions. Kelly reiterated that no single metric should be used in isolation to determine market timing, but the equity-to-GDP ratio remains a useful gauge of overall market valuation.
