Caro, there are so many more tech headlines out there today.

Boy, are there, and around compute and such.

We're talking SoftBank first.

It stopped talks to buy data center operator Switch.

Now, that's according to sources.

The company has been pursuing Switch for months, offering as much as $50 billion, but the deal would have helped build out SoftBank's Stargate AI infrastructure.

Discussions continue, though, for a partial investment or a partnership.

Plus, Samsung is getting close to securing a certification from Nvidia for its latest AI memory chip, the HBM4.

Sources say the South Korean company has entered the final qualification phase after supplying samples to the US chipmaker in September.

Samsung is said to be preparing mass production of the HBM4 in February.

And shares of USA Rare Earth, they're surging.

The company entered a non-binding letter of intent with the United States Commerce Department for $1.6 billion in funding in exchange for 16.1 million shares and warrants.

Now, the company also raised $1.5 billion in private investment to accelerate domestic heavy rare earth production.

Multi-billion dollar circular deals.

Huge, huge sums of money are just being passed between these enormous companies that are pouring hundreds of billions of dollars into the promise of AI.

Probably the biggest question in San Francisco right now is are we in an AI bubble?

And if we are, then well, how big is this bubble and how bad would it be if and when it does burst?

You can watch the full episode of that Bloomberg Originals piece on YouTube and Bloomberg.com.

We have another alleged example of circular financing just today.

NVIDIA investing another additional $2 billion into CoreWeave.
