S&P 500 profit margins have reached the highest level on record going back to 2009, according to FactSet data, giving equity markets yet another structural reason to keep climbing.
The index’s blended net profit margin for the second quarter of 2026 stands at 16.9%, up from 14.8% in the first quarter and 12.9% a year earlier, and well above the five-year average of 12.4%. John Butters, senior earnings analyst and vice president at FactSet, notes that if the 16.9% figure holds through the remainder of reporting season, it would surpass the previous record of 14.8% set just one quarter prior.
Alphabet and Amazon Are Driving S&P 500 Profit Margins to New Peaks
The two most consequential contributors to the record are Alphabet (GOOGL) and Amazon (AMZN), each of which posted numbers that stretched the boundaries of what large-cap income statements typically look like.
Alphabet’s second-quarter results were dominated by a gain on equity securities. The company’s official earnings release shows ‘Other income (expense), net’ of $97.983 billion for the quarter, driven by $99.031 billion in gains on equity securities, compared with $1.286 billion in the same period a year earlier. Total revenue came in at $119.8 billion, up 24% year over year, while net income available to common stockholders reached $112.1 billion, a 298% increase year over year. The Google parent also expanded its operating margin to 34%, from 32% in the second quarter of 2025.
Amazon’s story runs along similar lines. The company reported net income of $62.6 billion, or $5.75 per diluted share, compared with $18.2 billion, or $1.68 per diluted share, in the year-ago quarter, according to Amazon’s Q2 2026 earnings release. A $53.4 billion net other-income contribution, largely tied to its investment in Anthropic, amplified the bottom line. Operating margin widened to 13.7% from 11.4% a year ago.
Strip both companies out and the index’s net profit margin still registers at 15%, itself a record for the S&P 500 going back to 2009. The breadth of the improvement complicates any argument that this is purely a mega-cap phenomenon.
Operating Leverage and Sector Mix Are Doing the Heavy Lifting
Eight of the 11 S&P 500 sectors are reporting higher margins than they were a year ago, led by technology, communication services, consumer discretionary, and energy.
Sector-level estimates from FactSet’s Earnings Insight report dated 10 July 2026 show the Information Technology sector’s net profit margin was expected at 30.7% for the second quarter, up from an estimated 25.2% in the same period a year earlier. Energy’s expected margin moved from 7.7% to 13.4% over the same window. Both figures are estimates from that mid-July report; the final blended readings may differ once all results are in.
Adam Schickling, a senior economist at Vanguard, pointed to operating leverage as the engine behind the broad improvement. ‘Businesses, when they’re busy, are more profitable,’ he told CNBC. ‘Firms are busier, they’re more efficient, and that translates into higher margins.’
Technology companies benefit disproportionately from that dynamic. Their asset-light models allow them to add customers without a proportionate rise in costs. ‘Tech companies just have higher profit margins than what you might see from materials, industrials, energy,’ Schickling said. ‘That is a sector prone to having a higher general profit margin, especially because it has historically been relatively asset-light, which means they’re able to scale up at a very efficient rate.’
Alphabet’s gross margin offers a concrete illustration: at 61.6% in the second quarter of 2026, up from 59.5% in the same quarter a year earlier, according to an analysis of Alphabet’s Q2 2026 results, the company is converting nearly two-thirds of every revenue dollar into gross profit before a single corporate expense is counted.
The earnings trajectory also has a forward dimension. FactSet data show S&P 500 companies are expected to report year-over-year earnings growth of 23.6% and revenue growth of 12.3% for the second quarter of 2026. Analysts are projecting earnings growth of 26.6% and revenue growth of 10.6% for the third quarter.
Schickling did flag one caveat worth watching: technology’s competitive landscape is filling with new entrants, and that pressure could eventually erode the margins that are currently flattering the index’s aggregate numbers. Whether the third-quarter projections hold will depend partly on whether that competitive friction has begun to bite.
