More #bubblewatch weekend notes:

Remember Thursday's short downturn in AI stocks the day after Nvidia released their self-fluffed earnings report? It was caused by AI trading systems flagging accounting fraud.

> The Algorithm That Detected a $610 Billion Fraud: How Machine Intelligence Exposed the AI Industry’s Circular Financing Scheme. https://substack.com/inbox/post/179453867

And the recovery afterwards? That is apparently human beings deciding the AI systems were full of shit.

Get your head around that…

The Algorithm That Detected a $610 Billion Fraud: How Machine Intelligence Exposed the AI Industry’s Circular Financing Scheme

On November 20, 2025, trading algorithms identified what may become the largest accounting fraud in technology history—not in months or years, but in 18 hours.

Monday 11-24 #bubblewatch

The market climb at the end of Friday is continuing. Apparently on the expectation the Fed will cut rates in December.

> Wall Street surges on tech rally, rate cut optimism. https://www.reuters.com/world/europe/wall-street-futures-mixed-investors-mull-fed-rate-cut-focus-data-2025-11-24/

This is a general upturn, but tech stocks are doing quite well. And yet a rate cut doesn't change fundamentals of the bubble, so this seems like the old saw: "The market can stay irrational longer than you can stay solvent."

Tuesday 11-25 #bubblewatch

This is the first time since I started this thread on 11-4 where a rise in the market on one day was followed by another rise on the second. Apparently this is everyone betting on Federal Reserve rate cuts.

> Wall Street advances as Federal Reserve rate cut bets gather momentum. https://www.reuters.com/business/us-futures-ease-with-investors-focus-data-alphabet-shines-2025-11-25/

Is this the end of the 'roller coaster' we've been seeing? Or just going for a longer drop?

Note again: a rate cut doesn't change bubble fundamentals.

Monday 12-1 #bubblewatch

Last week ended with the market rising generally amid optimism the Fed will cut the prime rate. Monday opens with a general drop (and a crypto free-fall) as Treasury Bond yields rise.

> Wall Street slips as yields rise, crypto stocks tumble. https://www.reuters.com/business/wall-st-futures-drop-caution-ahead-data-powells-remarks-2025-12-01/

This is all common market volatility, not yet the #AI econo-gedden many of us are expecting. But the roller coaster of the last few weeks has trended generally down.

Tuesday 12-2 #bubblewatch

I'd say the market was see-sawing, but I've already settled on 'roller coaster' for the metaphor. In any case, after two days of moderate 'up' we are back on the 'down one day, up the next' train. Err. Roller coaster.

As noted yesterday, the overall trend is 'down'. But right now everything is hanging on the Fed announcing a rate cut.

Wednesday 12-3 #bubblewatch

The market is apparently convinced the Fed will drop rates significantly. T-Bill yields continue to drop and stock prices are still edging up, although tech stocks not so much.

> Fed hopes fire risk rally. https://www.reuters.com/world/china/global-markets-trading-day-graphic-2025-12-03/

However, job data is *not* looking good. And, again, nothing has changed on the #AI bubble fundamentals; it's still unsustainable and only hanging on right now because of risk takers and greater fools.

Seattle NPR station KUOW has a report on the #AI #bubble.

> What happens to Seattle if the AI bubble pops? https://www.kuow.org/stories/what-happens-to-seattle-if-the-ai-bubble-pops

However, the story is dominated by an interview with Tim Porter – a Managing Director at Madrona (local vulture capital firm) – who is clearly motivated to deny it is a bubble. When pressed he admits to every aspect of why people believe it is a bubble, but never backs off his assertion it is *not* a bubble.

(Posting to archive a link, not recommended listening.)

What happens to Seattle if the AI bubble pops?

Companies are spending hundreds of billions of dollars to build the AI infrastructure of the future. But companies are struggling to make a profit on the AI of today. So, is that future real, or just a mirage?  

Wednesday 12-4 #bubblewatch

Mixed trading today. Many stocks held their ground with continued optimism over a Fed rate cut, but that same optimism was muted as government economic figures are missing or 'soft' and non-governmental figures (like ADP's employment numbers) are looking rather grim.

Monday 12-8 #bubblewatch

I didn't do a bubblewatch update last Thursday and Friday, partially because those days were merely a continuation of last Wednesday. The writeups stressed market optimism for Fed rate cuts, but the market itself showed only a marginal increase in value.

Today it seems that optimism has drained out…

Wednesday 12-10 #bubblewatch

The Fed has finally spoken and they have intoned, "One quarter of a percentage point will I give you!"

And despite the fact a quarter of a percentage point (0.0025%) isn't squat, there was much rejoicing and industrial stocks saw moderate gains.

Tech stocks, however? Again, let me point out the US GDP and Fed rates have little or nothing to do with the fundamentals of the AI bubble.

> S&P 500 gains ground after Fed cuts interest rates. https://www.reuters.com/business/wall-st-futures-slip-ahead-fed-meeting-2026-cuts-doubt-2025-12-10/

Late night update. As expected, Oracle's earnings report was disappointing to the punters. What I didn't expect was for Oracle shares to drop 11% in Asian market after-hours trading!

They might make it up in the morning with the USA markets open. But if the slide continues it could spread to other tech stocks. (Right now both S&P and Nasdaq futures are taking short hits.) I'll be watching this in the morning.

> Oracle knocks stocks as Fed's message drags on dollar. https://www.reuters.com/world/china/global-markets-wrapup-1-pix-2025-12-11/

NOTE: If you've been thinking about trying to set up a big short when the AI bubble finally pops, this could be a good time to take a small flyer – assuming you can afford to take a loss. Because it's likely not the time yet.

I don't think there's going to be any way to predict when the market's attitude makes that sudden turn against AI stocks and, sure, this could be it. But I don't think so.

I will enjoy watching Oracle get pummeled though. So I'm hoping for that much.

Here's an article on Oracle's sales forecast and earnings report:

> https://www.reuters.com/business/retail-consumer/oracle-reports-higher-quarterly-remaining-performance-obligations-2025-12-10/

As I predicted a couple of days ago, one of the things dragging Oracle down is uncleared debt. Some of it in the form of services paid for and not delivered.

And a lot of that is AI related. I'm wondering if some of those open obligations are actually circular deals like Nvidia was doing – IOW they were paid with ownership in the AI company buying the data center services.

Thursday 12-11 #bubblewatch

Last night Asian and futures markets were bearish on Oracle due to their disappointing earnings report and I suggested if this continued once USA markets opened this morning the malaise could spread to other tech stocks.

And … yeah…

This isn't the #AI #bubble popping. Yet. But the smarter investors are slowly easing their money out while it's still over-inflated.

Friday 12-12 #bubblewatch

The market rallied a bit by EOD yesterday, but that evaporated when it opened this morning, followed by tech stocks hitting two-week lows. Oracle and other #AI #bubble concerns were a big reason.

We might be edging our way up to the tipping point!

(I might need to post an update today once the USA markets close.)

Weekend #bubblewatch update.

The Oracle and Broadcom earnings reports are certainly having an effect on tech, and most especially #AI, stocks. But, as I suggested on Thursday, it's a bit muted and not the bubble popping.

> Oracle-Broadcom one-two punch hits AI trade, but investor optimism persists. https://www.reuters.com/business/finance/oracles-stumble-hits-ai-trade-many-remain-bullish-2025-12-12/

The key here? Some investors are taking their profits and walking away, but not enough to get the short players out of bed. There remains a LOT of incentivized optimism.

More:

@ChrisMayLA6 has an interesting chart showing one significant difference between the current #AI #bubble compared to both the 2000 Tech bubble and the 1989 Japan Finance bubble.

Of course this chart only includes big players with track records, which is fair. But a bit misleading for the AI bubble because the big players this time (aside from Tesla) were priced down in a way similar to IBM in previous bubbles. While smaller players are priced stupid high.

Not much to report. Market valuations are bouncing around, but mostly down; in general and not purely tech stocks. (In fact the Nasdaq is up a little from yesterday.)

Thursday 12-18 #bubblewatch

Today tech stocks had a small rally, but didn't make up losses earlier in the week. Memory chip makers did especially well, no surprise to anyone who's been watching the effect of #AI companies on that market.

> Wall St closes higher fueled by tech rally, soft inflation data. https://www.reuters.com/sustainability/sustainable-finance-reporting/wall-st-futures-climb-run-up-inflation-data-micron-gains-2025-12-18/

The bubble isn't popping yet folks. But it does seem to have stopped expanding for the last week.

And, no, I have no idea what that means. Nor am I willing to guess.

Friday 12-19 #bubblewatch

And the tech stock rally continues, although two things:

1. I don't think most tech stocks made up for losses earlier in the week

2. This rally is on the back of a strong earnings forecast from Micron Technology today – and said forecast is based on continued #AI #bubble spending; expect analysts to call this out on Monday

That said, I think today is probably the high-water mark for the week and we'll see a drop in remaining trading days. It's been a pattern for a while now.

Tuesday 12-23 #bubblewatch

I was expecting the market to drop a bit today and tomorrow, but the 3rd quarter US gov economic data dropped last night and the market loves it. (I find the reported data rather suspect myself, but then I find everything from the government suspect these days.)

From now until the second trading day of January, all market movements will be entirely disconnected from fundamentals and logic.

NOTICE: I'm suspending #bubblewatch until the market, currently caught up in a 'Santa Claus Rally' buoyed by suspect government economic data, resumes a semblance of rationality on the third trading day of January.

Monday 1-5 #bubblewatch is BACK!

During the holidays while bubblewatch was suspended the 'Santa Claus Rally' mostly failed to happen, due to tech stock worries.

Wednesday 1-7 #bubblewatch

The USA jobs report came out today and … not glowing. In fact indications of a downturn. Given my concerns about government data from this administration I'm wondering if they massaged those numbers from even worse ones.

In any case the market REALLY wants to stay optimistic. I can't help but feel like it's a perky gym worker trying to rally an exhausted cardio class.

I'm still working my way through it. The first third is a mid-level introduction to how LLM AI actually works, so it might be skippable. Nonetheless I found it worth my time for a few things I didn't know.

Talking With Paul Kedrosky

So, about this AI thing ...

Paul Krugman

OK, finished it. Some key points I picked up on:

- AI is a *resource extraction economy*! The capex for physical data centers is only a portion of the cost of the chips in those data centers, which they are burning out faster than normal lifetimes.

- The other resource is data to feed the models – and they are running out because they've already mined the entire Internet and every book they could find. Like an oil well going dry.

- Yet another resource is *electricity futures*!

[contd]

- Since power is so important to the data centers they have been buying up contracts for future electricity production; which not only drives up the cost of electricity, there's only so much new power generation you can spin up within the contract's lifetime. As a result it's getting harder and harder to find someone willing to sell electricity futures.

- But, since new powerplants are already coming online as a result? It's distorting the current market. FIFO in action.

[contd]

- Separately, the snake oil sales pitch to 'replace human labor' doesn't take into account the side-effects on the economy of replacing human labor at scale.

- Given all the things said above (and others)? Future revenue predictions for AI are not just inflated, they are pure fiction. And that's assuming the LLMs actually *can* replace human labor at scale.

- There does seem to be a future in more limited models (the Chinese method).

- This might be the biggest bubble *ever*.
