The S&P 500 rose 0.72% to close at 7,730.99 on August 27, 2026, as Nvidia’s blowout earnings and upbeat guidance lifted technology stocks and eased investor concerns about artificial intelligence spending. Nvidia shares surged 8.7%, adding a record $441.5 billion to the company’s market capitalization, which reached $5.49 trillion.
Nvidia reported second-quarter revenue of $96.2 billion, exceeding analyst expectations, and guided third-quarter revenue to $108 billion—well above the consensus estimate of around $104 billion. The chipmaker also signaled that fiscal 2028 revenue is expected to grow approximately 70%, suggesting sustained momentum in AI demand.
The market’s reaction reflected relief that the world’s dominant AI chip supplier saw no signs of a slowdown despite months of debate over whether companies were spending too heavily on artificial intelligence infrastructure. Nvidia’s results came after several weeks of volatility in technology stocks driven by concerns over AI capital expenditure sustainability.
Tech stocks broadly benefited from Nvidia’s strength. The Nasdaq Composite surged 1.57%, while the Philadelphia Semiconductor Index jumped 2.33%. The broader rally underscores how dependent the 2026 market advance has been on the technology sector. According to recent data, S&P 500 earnings are on pace to grow more than 31% for the second quarter alone, with technology companies driving much of that expansion. Earlier in the year, just three AI hyperscalers—Alphabet, Amazon, and Meta—accounted for 70% of S&P 500 earnings growth expectations for the full year.
Nvidia’s guidance beat was particularly significant because it suggested the company’s customers—cloud providers and enterprises building out AI systems—remain committed to large capital investments. CEO Jensen Huang’s commentary on the earnings call reinforced confidence that AI adoption is accelerating rather than plateauing, a message the market has been hungry to hear after weeks of skepticism.
The Dow Jones Industrial Average gained 0.20%, or 105.56 points, to 53,569.44. While the Dow’s gain lagged the broader market, the move reflected a modest rotation away from large-cap technology into other sectors. The S&P 500’s advance brought the index closer to its record high, which it has reached 27 times already in 2026, signaling continued strength in equities as earnings season progresses.
