U.S. equity futures edged higher on August 17, with technology stocks again setting the tone for global markets. Nasdaq futures rose 0.5% before the open, while S&P 500 futures added 0.1%, leaving the benchmark only a few basis points from another record high.
The latest push came from renewed confidence in artificial intelligence spending. Semiconductor, memory and mega-cap growth names outperformed after fresh revenue figures tied to the AI ecosystem reinforced the view that corporate investment in computing infrastructure remains strong.
That combination of resilient earnings momentum and easing rate-hike expectations has kept investors focused on tech stocks, even as bond yields remain elevated and the market heads toward a busy stretch that includes Federal Reserve minutes, Jackson Hole, and Nvidia earnings next week.

Tech Stocks and AI Spending Optimism
The market’s opening setup reflected a familiar pattern from 2026: investors returning to the biggest beneficiaries of the AI buildout. Chipmakers, memory names and large-cap platform companies led gains, while software stocks lagged. The divergence suggests investors still prefer the more direct infrastructure beneficiaries of AI spending over companies whose returns from AI adoption may take longer to materialize.
The most important catalyst was the latest evidence that demand tied to AI remains unusually strong. Anthropic’s preliminary second-quarter revenue of $11.5 billion, along with positive adjusted operating income, sharpened the case that spending on models, compute and supporting hardware is not fading. That matters because a large share of the market’s earnings leadership has come from companies exposed to AI data centers, networking, servers and advanced chips.
The move also comes after a volatile July, when investors briefly rotated into economically sensitive sectors and away from technology leadership. August trading suggests that rotation has not displaced the market’s core thesis. For now, investors appear willing to pay for earnings visibility, and the clearest visibility still sits in semiconductor and AI infrastructure names.
Fresh signs of AI revenue growth are reinforcing the market’s belief that the technology buildout still has room to run.
Why the next catalyst may matter even more
The near-term question is whether technology can extend its lead into Nvidia’s earnings next week. Nvidia remains one of the market’s most influential companies because its results shape expectations not only for chip demand, but also for spending plans across cloud, enterprise and sovereign AI projects.
Investors will also test whether the current rally can broaden. Small-cap stocks were slightly weaker in premarket trade, and defensive groups such as health care and staples lagged. If leadership remains narrow, index gains may continue, but portfolio risk becomes more concentrated in a smaller number of large-cap names.
Implications for Investors
For investors, the immediate takeaway is that market leadership remains tied to earnings strength rather than pure macro relief. Big technology companies have continued to dominate profit growth, with S&P 500 earnings per share up 31% in the second quarter from a year earlier. That backdrop supports continued interest in AI-linked equities, especially where demand is visible and balance sheets are strong.
At the same time, risks have not disappeared. Treasury yields remain high, the yield curve has been steepening, and markets still face key events including Fed minutes this week and the Jackson Hole gathering next week. Even if traders have pushed back the odds of another near-term rate hike, long-end yields can still pressure equity valuations, particularly for expensive growth stocks.
Investors should also monitor signals from outside technology. Retail earnings from Walmart, Home Depot and Target will provide a read on the health of the U.S. consumer after recent data pointed to softer July spending. If consumer-facing companies show more strain from slower hiring and high borrowing costs, markets may be forced to reassess the broader growth outlook even if AI-related profits remain robust.
Cross-asset signals are also worth watching. The U.S. dollar slid to a three-month low as rate-hike expectations faded, while copper pushed toward record levels and silver gained more than 1%. Those moves can support cyclical sentiment, but they also complicate the inflation picture if commodity strength persists. Meanwhile, the $389.7 million weekly outflow from spot Bitcoin ETFs highlights that speculative capital is not rising evenly across all risk assets.
Single-stock activity underscored the market’s selective nature. Marvell Technology rose 2%, Applied Optoelectronics added 2%, and Sandisk gained 4% in premarket trading as AI-linked names outperformed. Macy’s climbed 2% after Berkshire Hathaway disclosed a stake, while EyePoint plunged 66% after its late-stage trial missed its primary endpoint. L3Harris fell 3% after replacing its chief executive officer.
The broader lesson is that investors are still rewarding growth, visibility and strategic positioning, while punishing execution missteps quickly. In that environment, stock selection matters as much as sector allocation.
If Treasury yields stay contained and upcoming earnings confirm continued AI demand, technology stocks could keep driving index performance into late August. The next test will be whether that momentum broadens beyond semiconductors and mega-cap platforms, or becomes even more dependent on a handful of names.
