Stock market today: Dow rises 0.2%, Nasdaq falls 0.8% on AI jitters. The Silicon Data LLM Token Expenditure Index drops 20%, raising questions on big tech spending.
The stock market delivered mixed results on July 3, 2026, as the Dow Jones Industrial Average added 0.2%, buoyed by defensive sectors, while the tech-heavy Nasdaq Composite slid 0.8%. The S&P 500 ended flat, reflecting a narrow market where gains were concentrated in utilities and healthcare. The divergence underscores growing unease about the AI trade, which has fueled the bulk of this year's rally.
The Dow's modest advance was led by Johnson & Johnson and Procter & Gamble, typical safe havens during uncertainty. In contrast, tech stocks took a hit. Nvidia fell 2.5% and Broadcom dropped 3%, dragging the Philadelphia Semiconductor Index down 1.2%. The trigger: a sharp decline in a key AI pricing gauge.
The Silicon Data LLM Token Expenditure Index, which tracks what users pay for AI tokens, is down almost 20% from a high in May after nearly doubling since its inception in December.
The drop has reignited debates over whether the massive capital expenditure in AI — estimated at over $700 billion — will ever generate adequate returns. Investors are now questioning the valuation of companies that have bet heavily on AI infrastructure.
As the U.S. approaches the Fourth of July holiday, trading volumes are expected to thin, potentially amplifying volatility. For those looking to enjoy the break, our tech tips for celebrating the Cuatro de Julio holiday offer a welcome diversion.
The Silicon Data LLM Token Expenditure Index has been a bellwether for AI demand. Since its launch in December 2025, the index nearly doubled, reflecting surging usage and pricing power for AI model providers. But the recent 20% slide from its May peak signals a potential shift. The index blends price and volume, so a decline could mean:
Each scenario carries different implications. Price cuts might boost adoption but hurt margins. A shift to cheaper models could benefit companies like Meta, which recently announced plans to offer cloud services for AI computing. A genuine demand slowdown would be the most bearish, suggesting the AI boom is losing steam.
The index is now flashing a warning that profitability in AI may be further off than expected. The index's creator, Silicon Data, cautions against reading it as a pure price gauge, but investors are taking note. Veteran investor Louis Navellier said: “There are increasing reports that users of AI solutions, priced in tokens, are having to restrain unlimited use due to high costs. The chatter that OpenAI is pushing back its IPO to next year is seen as a sign that, currently, profitability remains a problem.”
The $700 billion capex cycle, led by hyperscalers like Microsoft, Amazon, and Google, has been a tailwind for chipmakers and data center builders. But if token prices continue to fall, those companies may face pressure to justify their spending. Meanwhile, Croatia's emerging tech hub shows that AI investment isn't limited to the usual suspects, though the market's current jitters could slow capital flows.
