The S&P 500's blended net profit margin climbed to a record 15.7% in Q2, the highest level since FactSet began tracking the metric in 2009. Alphabet's outsized net income drives a large share of that record, and stripping the company out drops the index's margin to about 14.4%.
Corporate America just posted its fattest profit margins on record, but one company's investment gains account for a large part of the gain. The S&P 500's blended net profit margin hit 15.7% in Q2, according to FactSet, topping the previous high of 14.8% set just one quarter earlier. That figure marks a jump from the 12.9% logged in Q2 2025 and the best reading since FactSet began tracking the metric in 2009.
Eighty-six percent of companies beat their earnings per share estimates during the quarter, and the index is now on track for its 10th consecutive quarter of earnings growth.
The Alphabet effect
Alphabet reported $112 billion in quarterly net income during Q2. Roughly $77 billion of that came from unrealized gains on various investments, including its stake in SpaceX. Strip Alphabet out of the calculation entirely, and the S&P 500's blended margin drops to around 14.4%.
That's still a solid number, but the gap between 15.7% and 14.4% shows how much a single company can move the needle for an index of 500. Unrealized gains are, by definition, unrealized, and they can reverse — a point that matters given how much of the record margin traces back to paper profits on venture-stage investments.
Broad strength, with caveats
Strength extends beyond Alphabet. Seven of the eleven S&P 500 sectors posted year-over-year margin improvements, and eight sectors beat their five-year average margins. Health care, however, stood out as a notable laggard, struggling with margin expansion relative to its peers.
What the second half looks like
Analysts project margins of approximately 14.6% for the back half of 2026 — a step down from Q2's record but still historically elevated. Wall Street therefore expects profitability to stay robust, just not at the peak levels inflated by Alphabet's investment gains. The stock market's underlying business results remain the more durable story once the outliers are stripped away.
