Dow tops 50,000 as Cisco surges on AI-driven results

For most Americans, record stock indexes remain a market headline, not a pay raise. On Thursday, the Dow Jones Industrial Average closed at 50,063.46, while the S&P 500 finished at 7,501.24 and the Nasdaq Composite at 26,635.22, all fresh records driven by a narrow burst of AI enthusiasm.

Cisco Systems sat at the center of the move. Its shares jumped about 13% after the company posted fiscal first-quarter revenue of $14.9 billion, topped expectations with guidance for $15.0 billion to $15.2 billion in the next quarter, and lifted its full-year forecast to $60.2 billion to $61.0 billion. Cisco also said AI infrastructure orders from hyperscaler customers totaled $1.3 billion in the quarter, product orders rose 13% from a year earlier, and it would cut almost 4,000 jobs. CEO Chuck Robbins said there was "very strong, broad-based demand."

The earnings report gave investors another reason to bet that the AI buildout is still in its early innings. Cisco had already said fiscal 2025 revenue reached $56.7 billion, and that AI infrastructure orders from webscale customers exceeded $2 billion, more than double its original target. That makes Cisco one of the clearest beneficiaries of the spending race around data-center networking, routers and other gear that sits behind the biggest AI systems.

The rally did not stop with Cisco. Nvidia climbed more than 4% after the U.S. cleared about 10 Chinese firms to buy its H200 chip, even though no deliveries had been made. Cerebras Systems added to the fever with a $5.55 billion IPO, then saw its shares double to about $365 shortly after trading began. BlackRock strategist Gargi Pal Chaudhuri said the market remained AI-led, but that the impact was broadening into semiconductors, infrastructure and parts of the industrial economy.

That broadening matters, but it does not erase the concentration risk. The Dow's 52-week range, from 41,354.09 to 50,512.79, showed how quickly the benchmark has moved, and the day’s gains came as Donald Trump and Xi Jinping met to discuss trade and security issues, with Iran and the Strait of Hormuz also part of the conversation. For now, Wall Street's new milestone still depends on a small group of companies, heavy capital spending and policy decisions that can shift fast. The rally is real; the question is how much of it reflects durable earnings power rather than a powerful, increasingly crowded bet on AI.
