The S&P 500 rose 13.5% in 2026, easily outpacing the 3.4% rise in US consumer prices over the 12 months through July. It's the latest year in which stocks have beaten inflation, a feat accomplished in 16 of the past 20 calendar years.
A Decade of Beating Inflation
Historical data show the index has consistently outrun price growth. The Kobeissi Letter calculated a 14.76% real return in 2025 after accounting for 2.70% inflation, following real gains of 21.47% in 2024 and 22.11% in 2023. The four years when stocks failed to beat inflation were 2008, 2011, 2018, and 2022. Three of those — 2008, 2011, and 2018 — ended with inflation below 3%. In December 2008, consumer prices rose just 0.1% while the S&P 500 plunged 37%. The exception was 2022, when the BLS reported a 6.5% year-over-year increase in December and the index fell 18.11%, producing a real loss of roughly 23%.
Only three years in the 20-year period ended with December inflation above 4%: 2007, 2021, and 2022. The S&P 500 outpaced inflation in 2007 and 2021 but fell short in 2022. The largest real return came in 2013, when the index gained 30.42% and inflation stood at 1.5%.
Earnings Did the Heavy Lifting
This year's gain wasn't just a valuation story. First Trust calculated that 13.5 of the index's 17.9 percentage points came from higher earnings per share. That's a sign the rally has fundamental support, not just multiple expansion. Looking ahead, FactSet projects 28.2% year-over-year earnings growth for the S&P 500 in Q3 2026 and 31.2% for the full year.
Calm Markets, Quiet Volatility
The market has been unusually steady lately. As of August 30, 2026, the S&P 500 had traded for 22 consecutive sessions without a decline of at least 1.0%. The VIX closed at or below 16 points for 18 straight trading days, finishing at 14.4 on Friday. That kind of calm often precedes a jolt, but for now, investors are comfortable.
The Concentration Risk
Not everyone is convinced the rally is broad-based. Ben Snider of Goldman Sachs Research said in May that AI infrastructure beneficiaries should supply roughly half of index earnings growth this year, and flagged narrowing market breadth as a risk signal. Nine of the decade's 10 best S&P 500 performers trace to the AI infrastructure buildout, with Nvidia leading by a wide margin with gains above 13,000%. That concentration means a stumble in a handful of names could hit the whole index.
Inflation has cooled since the spring — consumer prices rose 4.25% in the year through May before easing to 3.4% in July. The next test comes in the third-quarter earnings season, when FactSet's projections will be put to the test. If earnings growth comes in as expected, the rally may have room to run. If not, the quiet tape could get noisy fast.
