Sometimes the stars align perfectly for a sector, and Thursday was one of those days for semiconductors. Nvidia Corp. (NVDA) delivered yet another earnings report that made Wall Street analysts look conservative, while rumors circulated that the Trump administration might pump the brakes on its aggressive tariff plans for chip imports. The result? A sector-wide rally that lifted everything from AI giants to memory chip makers.

Nvidia Keeps the Streak Alive

Let's start with the earnings, because they were characteristically impressive. Nvidia posted record third-quarter revenue of $57.0 billion, representing a 62% jump year-over-year and comfortably clearing Wall Street's estimates. Earnings per share came in at $1.30, also beating forecasts. This marks the company's 12th consecutive quarter of beating expectations on both revenue and earnings, which at this point is less surprising than it is just methodically dominant.

The real engine behind the numbers? Data centers, where revenue surged 66% to $51.2 billion. That's where the AI compute gold rush is happening, and Nvidia continues to be the primary supplier of shovels. Gaming, professional visualization, and automotive segments also posted solid gains, but data centers are clearly running the show.

Looking forward, Nvidia expects fourth-quarter revenue between $63.7 billion and $66.3 billion, ahead of what analysts had penciled in. The company cited soaring demand for AI compute power and strong adoption of its latest Blackwell platform as key drivers. In other words, the AI spending spree shows no signs of slowing down.

A Tariff Timeout?

The second piece of good news came from Washington, though it's a bit murkier. According to Reuters, U.S. officials have been privately signaling that they may delay imposing long-promised semiconductor tariffs, which would slow a major component of President Donald Trump's economic agenda.

Here's the backstory: Trump previously pledged a 100% tariff on imported chips, with exemptions only for companies that manufacture or commit to manufacturing semiconductors in the United States. That's a massive tariff rate that would fundamentally reshape the economics of the chip industry.

But now, officials have reportedly told government and industry stakeholders in recent days that the administration is taking a more cautious approach. The goal is to avoid provoking China and triggering a renewed trade conflict that could disrupt critical rare earth mineral supplies. Those minerals are essential for semiconductor manufacturing, and China controls much of the global supply.

The timing matters because Trump recently met with Chinese President Xi Jinping and appears to want to preserve what's been described as a fragile trade truce with Beijing. New chip tariffs would almost certainly test that relationship. They'd also raise costs on a wide range of consumer electronics, from smartphones to appliances, which isn't exactly popular policy heading into an election cycle.

The Broader Semiconductor Rally

With Nvidia's earnings strength and the tariff uncertainty potentially resolving in a favorable direction, semiconductor stocks rallied across the board. Advanced Micro Devices, Inc. (AMD), Broadcom Inc. (AVGO), Marvell Technology, Inc. (MRVL), Taiwan Semiconductor Manufacturing Company Ltd. (TSM), Micron Technology, Inc. (MU), Arm Holdings plc (ARM), and other chip players all traded higher on Thursday.

The sector is also getting a boost from an exciting earnings season overall and new strategic partnerships, including a semiconductor alliance between Nvidia and Saudi Arabia's Humain to bring advanced Arabic AI capabilities to market.

NVDA Price Action: Nvidia shares were trading higher by 3.65% to $193.35 at last check Thursday.
