Key Discussion Points

Broad Selloff in Tech Stocks

Magnitude of Drop: Major tech companies saw a steep decline in their stock values. Nvidia and Amazon were singled out as leaders of this downward movement.
- “By mid afternoon, Nvidia was down more than 3% while Amazon was down nearly 3%. Most of the Magnificent Seven stocks slipped.”

Investor Concerns: The decline follows Nvidia’s announcement of a major investment in OpenAI.
- Nvidia pledged up to $100 billion for OpenAI to build data centers.
- Questions are arising over a “circular economy,” wherein Nvidia invests in AI firms, which in turn buy more Nvidia chips.
- “Some investors appear to be concerned about a potential circular economy. In other words, whether there's actual demand for Nvidia chips or if Nvidia is investing in AI companies that then use those funds to buy more of its chips.”

Amazon’s UK Store Restructuring

Amazon Fresh Closures: Amazon will shutter 14 of its cashier-less Amazon Fresh stores in the UK, and the remaining five will be converted into Whole Foods locations.

- The restructuring marks a strategic pivot emphasizing online and delivery models over physical presence.

US Startup Hiring & the $100,000 H1 Visa Fee

New Policy Impact: President Trump’s recent executive order creates a $100,000 fee for H1-B visa applications, aiming to discourage companies from hiring lower-paid foreign workers in place of Americans.
- “US Startups are rethinking their hiring plans following the new hundred thousand dollar H1 visa fee that President Trump announced last week. Trump's executive order says the fee is meant to discourage replacing American workers with lower paid foreign ones.”
  — Julie Chang [01:13]
Startup Reaction:
- Startups are considering hiring more foreign contractors remotely or expanding international offices instead.
- Well-funded companies may still choose to absorb the cost in rare cases.
- Venture investors observed the fee could dissuade foreigners from founding startups in the US:
  - “Venture investors have told the WSJ that the high fee will deter foreigners from founding startups in the US.”

I'm Julie Chang for the Wall Street Journal. Tech stocks saw a broad sell off this afternoon. Investor favorites Nvidia and Amazon led the way lower. By mid afternoon, Nvidia was down more than 3% while Amazon was down nearly 3%. Most of the Magnificent Seven stocks slipped. This comes a day after Nvidia announced that it would invest up to $100 billion in OpenAI to fund a data center buildout. Some investors appear to be concerned about a potential circular economy. In other words, whether there's actual demand for Nvidia chips or if Nvidia is investing in AI companies that then use those funds to buy more of its chips. Amazon plans to shut down 14 of its brick and mortar Amazon Fresh stores in the UK and convert the other five it runs there into Whole Foods locations. Amazon Fresh stores operate with technology instead of cashiers, and the E commerce giant opened its UK stores four years ago. The company also says it'll roll out same day delivery for perishable groceries in the country, and it aims to at least double the number of prime members who can access three or more grocery delivery options through its local partnerships. And US Startups are rethinking their hiring plans following the new hundred thousand dollar H1 visa fee that President Trump announced last week. Trump's executive order says the fee is meant to discourage replacing American workers with lower paid foreign ones. The WSJ has spoken with some founders who say in response to the fee they plan to hire more foreign contractors remotely or rely more on international offices among well funded companies. Some aren't ruling out paying the fee in rare cases. Meanwhile, venture investors have told the WSJ that the high fee will deter foreigners from founding startups in the US and that's it for your T and B tech minutes.
