What happened this week in regard to AI and Chip losses?

 begin quotes:

 

Major tech and AI-related chip stocks suffered severe market losses, wiping over $1 trillion off the sector's combined value. The sell-off was triggered by mounting investor skepticism about whether massive, debt-funded capital spending on AI infrastructure (such as data centers and hardware) will ever yield profitable returns. 

Specific events this week include:

• Massive Market Sell-offs: The Nasdaq and S&P 500 tumbled, with the chip index plunging 7.9%. Companies like Amazon, Nvidia, and AMD saw heavy share price declines over the week. 
• OpenAI IPO Rumors and Custom Silicon: Risk sentiment took an additional hit following reports that OpenAI was considering delaying its FPO until next year. Meanwhile, OpenAI and Broadcom revealed their first custom AI chip partnership (named Jalapeno) aimed at lowering computing costs. 
• Corporate Squeeze on Memory: While chipmakers like Micron and SK Hynix posted blowout sales, soaring High-Bandwidth Memory (HBM) costs squeezed profit margins for other tech giants. Notably, Apple was forced to raise MacBook and iPad prices to offset these soaring memory and storage component costs. 

If you want, I can:

• Detail the specific revenue reports from companies like Micron and Nvidia
• Explain how the rising interest rate environment worsened the tech sell-off
• Break down the custom silicon race between AI startups and semiconductor giants
