The AI money is going in circles now, and SoftBank just put it in an SEC filing.

THE CIRCULAR MACHINE

SoftBank's power company filed to go public. Read the fine print.

I opened the S-1 this morning and stopped on one line.

SB Energy, a SoftBank company that builds power for AI, told the SEC it is substantially dependent on OpenAI.

OpenAI is its tenant. Its investor. And the reason it exists.

That one sentence is the whole AI economy right now.

Follow The Money

Today the AI story is not a model. It's a loop.

Nvidia funds OpenAI. OpenAI leases data centers from SoftBank. SoftBank's power arm depends on OpenAI. Nvidia sells the chips that fill the buildings. The money keeps circling back to the same handful of names.

Across the Industry

⚡ SB Energy files to IPO, leaning hard on OpenAI

SoftBank's AI power company filed for a U.S. IPO on the Nasdaq under the ticker SBE. It aims to raise between $5 billion and $7 billion, and no data center capacity is currently operational.

Here's the wild part. SB Energy incurred $3.2 billion in net losses during the first half of 2026 while generating $139 million revenue.

Why it matters: a company with no running data centers and huge losses wants public money. Nvidia has committed to invest $1.5 billion in a private placement at the IPO price, while OpenAI has been issued warrants worth roughly $5.5 billion. The buyers are also the customers.

🧠 Nvidia moves to buy the GitHub of AI

Nvidia already owns the chips. Now it wants the town square. Nvidia reportedly agreed to buy open source AI platform Hugging Face for $12.9 billion as the chipmaker expands deeper into the AI ecosystem.

Hugging Face is where developers grab open models, meaning free AI you can run yourself.

Why it matters: those who download open-source models from Hugging Face need to host and run those models on their own computing infrastructure, which usually involves Nvidia's GPUs. Whoever controls the shelf controls the store. One caveat: this is not a signed, announced deal, and multiple outlets describe the talks as ongoing.

🔌 OpenAI cuts off Cursor because Musk owns it now

This one is personal. OpenAI notified SpaceX that it intends to wind down its contract providing OpenAI models to Cursor, with a proposed shutoff date of November 12, 2026.

Cursor is a popular AI coding tool. SpaceX bought it. And SpaceX now also owns xAI and X.

Why it matters: OpenAI said it cannot be confident that SpaceX will use its technology within its terms of service, based on its experience with Elon Musk's companies violating contracts. The Altman-Musk feud is now redrawing which AI runs inside which app. Only about 5% of Cursor users are affected, and alternatives are already in place.

❤️ An AI reads a heart test in under two seconds

Not every story today is about money. Doctors have developed a "superhuman" AI tool that can spot heart disease in less than two seconds, extracting more information from a routine electrocardiogram than the human eye can typically see.

An ECG records the heart's electrical activity. It's cheap and everywhere.

Why it matters: a normal ECG cannot detect heart disease, which requires an echocardiogram, a type of ultrasound scan that patients often wait months for. Researchers trained the AI on more than 1.6 million ECGs from Brazil and several million recordings from the United States. This is AI doing something plainly good.

🇨🇳 DeepSeek closes in on a $74 billion valuation

The lab that shook everyone last year is stacking cash. The Wall Street Journal and South China Morning Post reported that DeepSeek is close to completing a new funding round valuing the company at roughly $74 billion prior to the investment.

The money is aimed at research and, of course, compute.

Why it matters: DeepSeek's revenue for 2026 up to July hit 475 million yuan, about $70.7 million, a tenfold jump on what it earned in all of 2025. The lab has begun preparing for a listing on Shanghai's Star Market, and a public debut is targeted for 2027. China's AI champion wants the public markets too.

The Numbers

$1 billion — ChatGPT ad run rate

OpenAI's ad business hit that annual pace in under 200 days. But analysts warn a run rate is a snapshot, not booked revenue.

~$439 billion — SB Energy contracted backlog

A giant promise on paper. The company still runs zero operational data centers today.

$12.9 billion — Nvidia's bid for Hugging Face

Reportedly its largest acquisition ever, nearly double what it paid for Mellanox in 2020.

The Main Event

The AI boom is now one giant loop of its own money

Read three filings today and you see the same shape.

SB Energy needs OpenAI to survive. Its own filing says its near-term revenues and development plans are significantly linked to OpenAI's continued performance under its lease.

Nvidia is funding the whole scene. It has poured $40 billion-plus into AI equity deals in 2026 alone, including a $30 billion OpenAI stake, deals critics call "circular financing."

The pattern is simple. Nvidia backs a company. That company buys Nvidia chips. Everyone's numbers go up together.

The companies say this isn't a trick. They have said the deals were not circular financing, but rather investments to accelerate the AI buildout. Fair. But the SEC filing says the quiet part out loud.

A wave of multi-billion-dollar AI, cloud and chip deals in the past few months has sharpened the scrutiny around AI's circular economy, where the biggest funders become the biggest customers.

Now zoom out. Buying Hugging Face is a different move. It's Nvidia owning the pipe, not just funding a customer. Buying Hugging Face outright is Nvidia owning infrastructure, not just funding a customer.

That's the real story of the day. The money is going in circles, and the biggest players are quietly buying every ring of the circle so they can't be cut out.

My take: this works beautifully until demand blinks. If AI usage grows, the loop looks like genius. If it stalls, the same wiring turns every company's problem into everyone's problem.

The Subtext Report

The IPO with a "please still love us" clause

SB Energy's filing mentions OpenAI 306 times and warns about angry neighbors who don't want data centers.

Mentions of OpenAI are almost as plentiful as SoftBank itself, showing up 306 times throughout the S-1. When your risk factors are your business plan, you know it's 2026.

Ads that click, invisibly

OpenAI announced its billion-dollar ad milestone on the same day advertisers got suspicious.

Agencies across North America posted documented evidence that the platform's dashboard was reporting clicks their analytics tools could not find. Nothing says trust like clicks only OpenAI can see.

I couldn't care less.
