The S&P 500 is on track to deliver another positive inflation-adjusted return in 2026, but the market’s gains are increasingly reliant on corporate profits holding up in a more challenging interest-rate environment.
The benchmark index has climbed approximately 12%–13% year to date through late August, comfortably outpacing recent U.S. inflation readings. The Consumer Price Index rose about 3.4% over the 12 months through July, while the Federal Reserve’s preferred personal consumption expenditures measure increased 3.7%. As a result, stock investors have achieved a substantial positive real return after accounting for higher consumer prices.
Corporate Earnings Are Driving More of the S&P 500 Rally
The key question for the 2026 stock-market rally is what is supporting it.
S&P 500 companies delivered exceptionally strong second-quarter results. FactSet reported that earnings growth reached its highest level since the second quarter of 2021, while Reuters estimated year-over-year second-quarter growth at approximately 33.5%.
FactSet also found that 86% of companies reporting through Aug. 7 exceeded earnings-per-share estimates. That compares with five-year and 10-year averages of 78% and 76%, respectively.
Analysts currently expect third-quarter earnings to grow by roughly 27%–28% year over year, with full-year profit growth projected at approximately 30%.
Those results give the equity rally a stronger fundamental foundation than a market advance driven solely by expanding valuation multiples.
Artificial intelligence remains a central part of the market’s growth story. Technology and communication-services companies have generated some of the strongest profit gains, while continued investment in AI infrastructure is supporting earnings expectations.
AI-related stocks have repeatedly helped lift the latest rally. Nvidia and other semiconductor companies helped push the S&P 500 toward record territory in August.
Inflation Still Matters as Stocks Rise
A positive nominal stock-market return does not necessarily translate into the same increase in purchasing power.
If the S&P 500 gains 13% while inflation reaches 3.5%, the simplified real return is approximately:
13% − 3.5% = 9.5%.
The precise inflation-adjusted calculation is slightly different because returns compound, but the subtraction offers a useful approximation.
Comparing stock-market performance with inflation also helps place record index levels in context. Investors care not only whether the S&P 500 rises, but whether those gains increase purchasing power faster than consumer prices.
Coinpaper’s guide to real yields explains the same concept from the bond-market perspective: inflation determines how much of a nominal investment return remains in real terms.
Higher Treasury Yields Pose a Growing Risk
The main challenge is that persistent inflation is keeping borrowing costs elevated.
The 30-year Treasury yield recently traded above 5.2%, near its highest level since 2007, while the 10-year yield has remained around 4.7%. Higher Treasury yields increase the returns investors can earn from relatively low-risk government debt and raise the discount rate applied to future corporate profits.
That pressure has already affected equities. The S&P 500 reached a record 7,798.99 on Aug. 13 before a bond selloff pushed stocks lower. The reversal was especially painful for highly valued technology and semiconductor shares.
Federal Reserve policy represents another risk. Markets sharply increased expectations for a September rate hike after Chair Kevin Warsh reiterated that inflation remained too high. Renewed pressure on oil prices has added another potential catalyst for inflation.
For investors, the outlook is more nuanced than the headline “stocks beat inflation.”
The S&P 500 is still generating a strong real return in 2026, and exceptional earnings growth is providing significant support. However, sustaining that advantage will increasingly depend on corporate profits growing quickly enough to offset persistent inflation, higher bond yields and tighter financial conditions.
