Nvidia on Tuesday said its tech remains a generation ahead of the industry, in response to Wall Street’s concerns that the company’s dominance of AI infrastructure could be threatened by Google’s AI chips.

“We’re delighted by Google’s success — they’ve made great advances in AI and we continue to supply to Google,” Nvidia said in a post on X. “NVIDIA is a generation ahead of the industry — it’s the only platform that runs every AI model and does it everywhere computing is done.”

The post came after Nvidia saw its shares fall 3% on Tuesday after a report that Meta, one of its key customers, could strike a deal with Google to use its tensor processing units for its data centers.

In its post, Nvidia said its chips are more flexible and powerful compared with so-called ASIC chips — such as Google’s TPUs — which are designed for a single company or function. Nvidia’s latest generation of chips are known as Blackwell.

“NVIDIA offers greater performance, versatility, and fungibility than ASICs,” Nvidia said in its post.

Nvidia has more than 90% of the market for artificial intelligence chips with its graphics processors, analysts say, but Google’s in-house chips have gotten increased attention in recent weeks as a viable alternative to the Blackwell chips, which are expensive but powerful.

Unlike Nvidia, Google doesn’t sell its TPU chips to other companies, but it uses them for internal tasks and allows companies to rent them through Google Cloud.

Earlier this month, Google released Gemini 3, a well-reviewed state-of-the-art AI model that was trained on the company’s TPUs, not Nvidia GPUs.

“We are experiencing accelerating demand for both our custom TPUs and Nvidia GPUs,” a Google spokesperson said in a statement. “We are committed to supporting both, as we have for years.”

Nvidia CEO Jensen Huang addressed rising TPU competition on an earnings call earlier this month, noting that Google was a customer for his company’s GPU chips and that Gemini can run on Nvidia’s technology.

He also mentioned that he was in touch with Demis Hassabis, the CEO of Google DeepMind.

Huang said that Hassabis texted him to say that the tech industry theory that using more chips and data will create more powerful AI models — often called “scaling laws” by AI developers — is “intact.” Nvidia says that scaling laws will lead to even more demand for the company’s chips and systems.

WATCH: Meta reportedly in talks to use Google’s AI chips

Elon Musk’s artificial intelligence startup xAI is expected to close a $15 billion round at a $230 billion pre-money valuation next month, sources familiar with the matter told CNBC’s David Faber.

The deadline for allocation is the end of day on Tuesday, with the round expected to close on Dec. 19, the sources said.

This confirms earlier CNBC reporting that the company was raising $15 billion. The Tesla CEO later called the report on the round “False” in a post on the social media platform X.

At the time, sources told CNBC that xAI would use a large portion of the money for funding graphics processing units responsible for powering large language models.

CNBC had previously reported in September that the startup was looking to raise $10 billion at a $200 billion valuation.

The funding round is yet another sign of the insatiable demand for AI tools. Companies, including OpenAI and Anthropic, have raised billions and reached sky-high valuations as investors pour more money into companies building foundational AI models.

Sam Altman‘s OpenAI finalized a $6.6 billion-share sale at a $500 billion valuation last month, and Reuters recently reported that the ChatGPT maker was eying a $1 trillion initial public offering.

Anthropic closed a $13 billion funding round in September that roughly tripled its valuation from March.

Musk’s xAI is responsible for creating the Grok chatbot that has come under fire for disseminating hate speech, including antisemitic content. The company recently debuted Grokipedia, an AI-powered competitor to Wikipedia.

In March, Musk announced the merger of xAI with X in a deal valuing the social media platform at $33 billion.

TSMC on Tuesday filed a lawsuit against a former senior vice president it accused of leaking “confidential information” to Intel.

Wei-Jen Lo joined Intel after 21 years at TSMC, having left in July, the Taiwanese chip maker said in a statement, announcing the lawsuit.

The lawsuit is based on Lo’s employment contract and non-compete agreement with TSMC, and regulations such as the Trade Secrets Act, the statement said.

“There is a high probability that Lo uses, leaks, discloses, delivers, or transfers TSMC’s trade
secrets and confidential information to Intel,” it said.

TSMC’s share price fell on Tuesday and was last seen over 3% lower.

Intel did not immediately respond to CNBC’s request for comment.

It follows earlier reports by local media and later by Reuters, which stated Lo may have taken TSMC’s technology data to Intel. Taiwan’s High Prosecutors opened an investigation into the allegations.

Intel CEO Lip-Bu Tan told Bloomberg News last week that his “company respects intellectual property rights” and denied any wrongdoing.

The U.S. firm’s stock price moved 1.5% lower in mid-morning trade.
