Wharton professor and renowned economist Jeremy Siegel is bullish on a Big Tech boom fueled by artificial intelligence despite concerns of a bubble.
An AI chip craze, driven by demand for AI-powered chatbots and high-powered graphics processing units — used to train such chatbots on supercomputers — has seen investors piling into certain stocks with some raising concerns of a bubble.

“It’s not a bubble yet,” saidSiegel, Russell E. Palmer professor of finance at the Wharton School at The University of Pennsylvania, on CNBC’s “Street Signs Asia” Monday. He noted that he has been getting questions around whether it would lead to a repeat of the dot-com bubble in the late 1990s.
Economist David Rosenberg, known for his contrarian views, had predicted that the current AI boom could collapse like late 1990s dot-com stocks. The dotcom bubble burst when capital dried up after a massive adoption of the internet and a proliferation of available venture capital into internet-based companies, especially startups that had no track record of success.
“First, there was excitement about AI and Nvidia ratified that excitement with blowout earnings. That’s a double push,” said Siegel.
Nvidia CEO Jensen Huang said during the earnings call that the company was seeing “surging demand” for its data center products. Nvidia shares are up 166% year-to-date.
“[In the] long term I would say that [Nvidia shares] were probably slightly overvalued. But for the short term, we know momentum can carry stocks far higher than their fundamental value, and no one can predict how high they might go,” said Siegel.

On Sunday, Nvidia announced a new class of large-memory AI supercomputer created to enable the development of giant, next-generation models for generative AI language applications. The supercomputer powered by Nvidia GH200 Grace Hopper Superchip is expected to provide nearly 500 times more memory than the previous generation Nvidia DGX A100 — which was introduced in 2020.
“Generative AI, large language models and recommender systems are the digital engines of the modern economy,” said Huang, in the press release. “DGX GH200 AI supercomputers integrate Nvidia’s most advanced accelerated computing and networking technologies to expand the frontier of AI.”
Wharton’s Siegel said that AI stocks have helped lift the S&P 500 and that it could become “a winner from the banking crisis.”
“As we all know that the top eight or nine companies have accounted for all the gains of the S&P 500. This year, the other 490 have been flat or down. Yes, [the] Nasdaq was oversold in 2022 and it did bounce back but I think AI has pushed those big cap tech stocks even higher,” said Siegel.
“Remember big cap stocks of any sort, whether they’re tech or not, don’t have to worry about the credit conditions. Yes, they have to worry about interest rates to be sure. The credit conditions are going to affect the small and mid size [companies],” said Siegel.
“The S&P could actually become a winner from the banking crisis.”

Google on Friday made the latest a splash in the AI talent wars, announcing an agreement to bring in Varun Mohan, co-founder and CEO of artificial intelligence coding startup Windsurf.
As part of the deal, Google will also hire other senior Windsurf research and development employees. Google is not investing in Windsurf, but the search giant will take a nonexclusive license to certain Windsurf technology, according to a person familiar with the matter. Windsurf remains free to license its technology to others.
“We’re excited to welcome some top AI coding talent from Windsurf’s team to Google DeepMind to advance our work in agentic coding,” a Google spokesperson wrote in an email. “We’re excited to continue bringing the benefits of Gemini to software developers everywhere.”
The deal between Google and Windsurf comes after the AI coding startup had been in talks with OpenAI for a $3 billion acquisition deal, CNBC reported in April. OpenAI did not immediately respond to a request for comment.
The move ratchets up the talent war in AI particularly among prominent companies. Meta has made lucrative job offers to several employees at OpenAI in recent weeks. Most notably, the Facebook parent added Scale AI founder Alexandr Wang to lead its AI strategy as part of a $14.3 billion investment into his startup.
Douglas Chen, another Windsurf co-founder, will be among those joining Google in the deal, Jeff Wang, the startup’s new interim CEO and its head of business for the past two years, wrote in a post on X.
“Most of Windsurf’s world-class team will continue to build the Windsurf product with the goal of maximizing its impact in the enterprise,” Wang wrote.
Windsurf has become more popular this year as an option for so-called vibe coding, which is the process of using new age AI tools to write code. Developers and non-developers have embraced the concept, leading to more revenue for Windsurf and competitors, such as Cursor, which OpenAI also looked at buying. All the interest has led investors to assign higher valuations to the startups.
This isn’t the first time Google has hired select people out of a startup. It did the same with Character.AI last summer. Amazon and Microsoft have also absorbed AI talent in this fashion, with the Adept and Inflection deals, respectively.
Microsoft is pushing an agent mode in its Visual Studio Code editor for vibe coding. In April, Microsoft CEO Satya Nadella said AI is composing as much of 30% of his company’s code.
The Verge reported the Google-Windsurf deal earlier on Friday.
Jensen Huang, CEO of Nvidia, holds a motherboard as he speaks during the Viva Technology conference dedicated to innovation and startups at Porte de Versailles exhibition center in Paris, France, on June 11, 2025.
The sale, which totals 225,000 shares, comes as part of Huang’s previously adopted plan in March to unload up to 6 million shares of Nvidia through the end of the year. He sold his first batch of stock from the agreement in June, equaling about $15 million.
Last year, the tech executive sold about $700 million worth of shares as part of a prearranged plan. Nvidia stock climbed about 1% Friday.
Huang’s net worth has skyrocketed as investors bet on Nvidia’s AI dominance and graphics processing units powering large language models.
The 62-year-old’s wealth has grown by more than a quarter, or about $29 billion, since the start of 2025 alone, based on Bloomberg’s Billionaires Index. His net worth last stood at $143 billion in the index, putting him neck-and-neck with Berkshire Hathaway‘s Warren Buffett at $144 billion.
Shortly after the market opened Friday, Fortune‘s analysis of net worth had Huang ahead of Buffett, with the Nvidia CEO at $143.7 billion and the Oracle of Omaha at $142.1 billion.

The company has also achieved its own notable milestones this year, as it prospers off the AI boom.
On Wednesday, the Santa Clara, California-based chipmaker became the first company to top a $4 trillion market capitalization, beating out both Microsoft and Apple. The chipmaker closed above that milestone Thursday as CNBC reported that the technology titan met with President Donald Trump.
Brooke Seawell, venture partner at New Enterprise Associates, sold about $24 million worth of Nvidia shares, according to an SEC filing. Seawell has been on the company’s board since 1997, according to the company.
Huang still holds more than 858 million shares of Nvidia, both directly and indirectly, in different partnerships and trusts.

Tesla will open a showroom in Mumbai, India next week, marking the U.S. electric carmakers first official foray into the country.
The one and a half hour launch event for the Tesla “Experience Center” will take place on July 15 at the Maker Maxity Mall in Bandra Kurla Complex in Mumbai, according to an event invitation seen by CNBC.
Along with the showroom display, which will feature the company’s cars, Tesla is also likely to officially launch direct sales to Indian customers.
The automaker has had its eye on India for a while and now appears to have stepped up efforts to launch locally.
In April, Tesla boss Elon Musk spoke with Indian Prime Minister Narendra Modi to discuss collaboration in areas including technology and innovation. That same month, the EV-maker’s finance chief said the company has been “very careful” in trying to figure out when to enter the market.
Tesla has no manufacturing operations in India, even though the country’s government is likely keen for the company to establish a factory. Instead the cars sold in India will need to be imported from Tesla’s other manufacturing locations in places like Shanghai, China, and Berlin, Germany.
As Tesla begins sales in India, it will come up against challenges from long-time Chinese rival BYD, as well as local player Tata Motors.
One potential challenge for Tesla comes by way of India’s import duties on electric vehicles, which stand at around 70%. India has tried to entice investment in the country by offering companies a reduced duty of 15% if they commit to invest $500 million and set up manufacturing locally.
HD Kumaraswamy, India’s minister for heavy industries, told reporters in June that Tesla is “not interested” in manufacturing in the country, according to a Reuters report.
Tesla is looking to recruit roles in Mumbai, job listings posted on LinkedIn . These include advisors working in showrooms, security, vehicle operators to collect data for its Autopilot feature and service technicians.
There are also roles being advertised in the Indian capital of New Delhi, including for store managers. It’s unclear if Tesla is planning to launch a showroom in the city.
