Tech stocks fell on Tuesday morning as concerns about high valuations and artificial intelligence resurfaced, dragging the tech-heavy Nasdaq Composite (^IXIC) nearly 2% lower.

Within tech, semiconductor stocks saw some of the biggest losses in early trading, with AMD (AMD), Intel (INTC), and Qualcomm (QCOM) dropping by over 7%, and Nvidia (NVDA) falling nearly 4%.

Shares of memory giant Micron (MU) declined by more than 11% ahead of the company’s third quarter earnings after the bell on Wednesday, which will provide another update on the broader AI build-out. On Monday, the company announced a strategic agreement with Anthropic, in which the memory maker will supply Anthropic (ANTH.PVT) with both memory and storage chips to support its data center goals.

Meanwhile, the competition for talent in the artificial intelligence arena continued to move major stocks. Alphabet stock (GOOG, GOOGL) continued to fall after senior research scientist and Nobel prize winner John Jumper announced he was leaving Google DeepMind AI to join rival Anthropic (ANTH.PVT).

Micron (MU) will report its third quarter earnings after the bell on Wednesday as the memory industry continues to see tailwinds from the global AI build-out.

Micron stock has soared a staggering 862% over the past 12 months and is up 316% since January. Rival memory maker SK Hynix (000660.KS) has seen similar stock movement, with shares rocketing 1,035% higher over the past 12 months and 348% year to date.

Those kinds of massive gains have raised concerns among some analysts and investors, but AI bulls say the proof is in the earnings numbers.

For Q3, Micron is expected to report earnings per share (EPS) of $20.39 on revenue of $35.5 billion, based on Bloomberg analyst consensus estimates. That would work out to a 967% year-over-year EPS increase from the $1.91 the company reported in Q3 last year.

Revenue would jump 281% from 9.3 billion in the year-ago quarter.

Nvidia (NVDA) is moving further into the biomedical space with a new software tool that equips AI agents to perform scientific work.

Called the BioNeMo Agent Toolkit, the software is agent-agnostic, meaning it can work with various AI agents, such as OpenAI's Codex (OPAI.PVT).

According to Nvidia vice president of healthcare Kimberly Powell, the toolkit equips AI agents with the knowledge necessary to perform specific medical research more efficiently.

"In the world of agents, the longer the agent is waiting … the more tokens you will be burning. And so we need to have accelerated tools for the agents to work with," Powell explained.

Think of the BioNeMo toolkit as a crash course in specific scientific and medical understanding for an AI agent.

Asking a general agent like OpenAI's Codex or Anthropic's (ANTH.PVT) Claude for highly specialized medical or scientific questions, Powell explained, would likely take some time, if the agents could answer at all.

Oracle (ORCL) has cut some 21,000 jobs over the past year as the company continued its massive push into the AI data center space.

In its annual 10-K filing with the Securities and Exchange Commission, Oracle said it had some 141,000 full-time employees. That's down from the 162,000 the company reported in 2025.

The layoffs come as Oracle spends massive sums on AI facilities. In its fiscal 2026, Oracle spent $55.7 billion on capital expenditures. That's a 162% increase from the $21.2 billion it spent in fiscal 2025. Adjusted revenue for 2026 was $67.4 billion.

That spending has sent Oracle's free cash flow plummeting nearly 6,000% to -$23.7 billion.

But Oracle has also reported remaining performance obligations (RPOs) worth $638 billion, up from $138 billion last year. The company has a five-year, $300 billion deal to provide data center capacity to OpenAI (OPAI.PVT), one of its largest AI agreements.

RPOs are the value of contracts that Oracle has signed but must still deliver on before it can realize the revenue.

Meta (META) on Tuesday debuted a new line of AI-powered smart glasses, dubbed simply Meta Glasses.

Unlike Meta's other smart glasses endeavors, which featured designs from EssilorLuxottica (EL.PA) brands Ray-Ban and Oakley, Meta Glasses were designed in-house by Meta. However, the company notes that it's introducing its latest smart glasses "in partnership" with the eyewear giant.

That also means Meta Glasses get a new starting launch price of $299. The company's second-generation Ray-Ban Meta smart glasses currently cost $379, while the Oakley Meta glasses start at $499.

"You really want to be able to be in many places in the market," Meta CTO and head of Reality Labs Andrew Bosworth said during a question and answer session at a prelaunch event in New York.

"Reaching people isn't just about design and style. It's also about the price point that you can reach, and so if you're going to be wearing the Ray-Ban Wayfarer … you pay a premium for that," Bosworth said.

The tech sector is leading markets lower on Tuesday morning as investors go risk off amid renewed concerns about Federal Reserve rate hikes and artificial intelligence spending.

The tech-heavy Nasdaq Composite (^IXIC) traded 1.8% lower around the open. Here’s a look at some of the most notable moves in early trading:

Micron (MU) fell more than 11% ahead of its quarterly results after the bell on Wednesday. Investors are looking for proof that data center demand remains robust to support the stock’s searing 276% gain year to date.

Nvidia (NVDA) fell 3% ahead of its shareholders’ meeting on Wednesday. The company announced on Tuesday a new agentic AI biomedical tool for medical researchers.

Alphabet (GOOG, GOOGL) declined by 0.5% and was on track to fall for the second day in a row after its Nobel prize-winning AI researcher John Jumper announced he was leaving DeepMind AI for Anthropic (ANTH.PVT).

Alphabet stock (GOOG, GOOGL) fell nearly 7% after its Google DeepMind AI senior research scientist John Jumper announced he is leaving the company.

Jumper, who won the 2024 Nobel Prize in chemistry for his work with the AI model AlphaFold, wrote on X that he will join rival AI company Anthropic (ANTH.PVT) after nearly nine years at Google.

Also on Monday, the Wall Street Journal reported that the company is investing $75 million into independent film studio A24.

According to the Journal, Google and A24, the studio behind movies such as "Backrooms" and "Marty Supreme," are teaming up to create new tools for movie production and distribution using Google's DeepMind AI unit.

The investment marks Google's first stake in a movie studio and comes as other entertainment companies, including Disney (DIS) and Netflix (NFLX), have toyed with AI deals, despite Hollywood's general reluctance to embrace the technology.

SpaceX (SPCX) stock fell again on Monday, now poised for three straight down days after a massive run-up following its IPO earlier this month. SpaceX also confirmed its first-ever bond issuance in a filing.

SpaceX shares were down another 9% in early trade on Monday, following a 3.6% drop on Thursday (US markets were closed on Friday for the Juneteenth national holiday) and a 5% drop on Wednesday. The three-day losing streak caps a big pop in the stock following its IPO and first day of trade on June 12th.

Also on Monday morning, SpaceX confirmed its first-ever bond sale in a filing. Although the company did not disclose the size of the bond offering, it confirmed that it "intends to use the net proceeds from the Notes offering to repay the outstanding borrowings under its bridge loan facility in full" and to cover other related fees and expenses. Bloomberg reported late last week that SpaceX was prepping an offering in the $20 billion range.

Yahoo Finance’s Ines Ferré reports:

Micron Technology (MU) stock surged nearly 5%, putting the memory chipmaker on pace to hit a fresh record on Monday ahead of its earnings this week. The rest of the chip complex was poised to climb to new highs, including memory and storage maker Sandisk (SNDK).

Micron stock jumped, along with the rest of the chipmaker space, as investors awaited the company's results on Wednesday, providing a bellwether for memory demand in AI inference.

UBS analyst Melissa Weathers recently raised the bank's price target for Micron to $1,500 per share, as demand for DRAM — the type of memory used for data centers, servers, and smartphones — is "still set to vastly outpace supply growth in the coming years, driven by more memory-intensive AI workloads."
