I appreciate the disclosures about Gemeni and Nano Banana, but does that start to feel a little like a conflict of interest or something similar in an article discussing their competition?
kart23•43m ago
The critiques of 'circular funding' don't really make sense to me. If you invest 20 billion and you get back 20 billion, your profit is the same. Sure your revenues look higher but investors have access to all that information and should be taking that into account, just like all the other financial data.

Michael Burry is betting against AI growth translating into real profits as a whole, not the circular funding.

belter•42m ago
>> If you invest 20 billion and you get back 20 billion

Its about keeping Wall Street bubble momentum, not financials.

kart23•36m ago
Isn't that the entire stock market for the last 20 years?
myhf•39m ago
It's certainly a problem when circular investment structures are used to get around legal limits on the amount of leverage or fractional reserve, or to dodge taxes from bringing offshore funds onshore.
londons_explore•27m ago
Plenty of sneaky ways of using different accounting years offshore to push taxes forward indefinitely too, since the profit is never present at the year end.
biggoodwolf•37m ago
if you invest 20 and get 20 then you got 0% profit
abakker•24m ago
0% NET accretive profit - the OP was saying that the invest/return wash doesn't affect prior profitability, just revenue. Obviously, the new profitability inclusive of the new revenue will actually by lower because of the zero margin wash trade.
nh23423fefe•8m ago
Why would you say that? If take cash and buy an asset I haven't lost money.
cyanydeez•5m ago
Depends on when 20 goes in and 20 comes out.

And how inflation and interest are accounted.

mvkel•26m ago
The problem is that stocks are often valued and traded on revenue growth, not profit[0] So circular funding generates stock price bumps when, as you said, there's no inherent value underneath. Creates a recipe for a crash.

[0] consider pagerduty, incredibly profitable with little revenue growth. Trading at 1.5X revenue, where high revenue growth, unprofitable companies are trading at 10X revenue.

mewpmewp2•14m ago
Both are taken into account. Potential profitability is taken into account with growth companies. Circular funding has no effect on that. With unprofitable companies case is made on how risky the company is and what the potential profit will be in the future.
cyanydeez•6m ago
Its crypto wash trading.
Jare•25m ago
Just because it's legal and in the open doesn't mean it's sound or not creating perverse incentives. Investors that "should be taking that into account" probably are, and hoping that they come out on top when the bubble bursts. That means pain for many people. Those are very valid reasons to point the finger and criticize.
whatshisface•18m ago
If you invest $100B and get back $40B in sales, you're investing $60B of money and $40B of your products. This is simple stuff. The question is whether or not it is a good investment. Probably not.
buzzin_•13m ago
It's worse than that. One side of the "circle" is 40 billion, the other side is 300. Why not just subtract it, and say 260 billion is going one way.

The real story is that Nvidia is accepting equity in their customers as a payment for their hardware. "What, you don't have cash to buy our chips? That's OK, you can pay by giving us 10% of everything you earn in perpetuity."

This has happened before, let's call it the "selling the goose that lays golden eggs scan." You can buy our machine that converts electricity into cash, but we will only take preorders, after all it is such a good deal. Then, after bulding the machines with the said preorder money, they of course plugged the machines in themselves instead of shipping them, claiming various "delays" in production. Here I'm talking about the bitcoin mining hardware when the said hardware first appeared.

Nvidia is doing similar thing, just instead of doing it 100% themselves, they are 10% in by acquiring the equity in their customers.

mr_toad•9m ago
Nvidia could have invested elsewhere, but they’re doubling down on AI.

Their shares have been tanking for a month, even after a very good earnings report, so perhaps the market seeks a little more diversity?

Pull our POV back far enough, and isn't "circular funding" just "The economy?"

Money circulates; it's what it does. The real question is to what extent circulation among a small group of firms is either collusion in disguise (i.e. decisionmaking by only one actual entity falsely measured as multiple independent entities) or a fragile ecosystem masquerading as a healthy one (i.e. an "island economy" where things look great in the current status quo, but the moment the fish go away the entire cycle instantly collapses).

> However, Groq’s architecture relies on SRAM (Static RAM). Since SRAM is typically built in logic fabs (like TSMC) alongside the processors themselves, it theoretically shouldn't face the same supply chain crunch as HBM.

It's true SRAM comes with your logic, you get a TSMC N3 (or N6 or whatever) wafer, you got SRAM. Unfortunately SRAM just doesn't have the capacity you have to augment with DRAM which you see companies like D-Matrix and Cerebras doing. Perhaps you can use cheaper/more available LPDDR or GDDR (Nvidia have done this themselves with Rubin CPX) but that also has supply issues.

Note it's not really about parameter storage (which you can ammorotize over multiple users) it's KV cache storage which gets you and that scales with the user count.

Now Groq does appear to be going for a pure SRAM play but if the easily available pure SRAM thing comes at some multiple of the capital cost of the DRAM thing it's not a simple escape hatch from DRAM availability.

jsheard•23m ago
SRAM scaling also hit a wall a while ago, so you can't really count on new processes allowing for significantly higher density in the future. That's more of a longer-term issue with the SRAM gambit that'll come into play after the DRAM shortage is over though - logic and DRAM will keep improving while SRAM probably stays more or less where it is now.
zozbot234•11m ago
You can still scale SRAM by stacking it in 3D layers, similar to the common approach now used with NAND flash. I think HBM DRAM is also directly stacked on-die to begin with, apparently that's the best approach to scaling memory bandwidth too.

It'll be interesting to see if we get any kind of non-NAND persistent memory in the near future, that might beat some performance metrics of both DRAM and NAND flash.

wtallis•6m ago
NAND is built with dozens of layers on one die. HBM DRAM is a dozen-ish dies stacked and interconnected with TSVs, but only one layer of memory cells per die. AMD's X3D CPUs have a single SRAM die stacked on top of the regular CPU+SRAM, with TSVs in the L3 cache to connect to the extra SRAM. I'm not aware of anyone shipping a product that stacks multiple SRAM dies; the tech definitely exists but it may not be economically feasible for any mass-produced product.
throw234678•24m ago
This post is written with its intellectual fly open. I'm not sure whether it was partly AI-generated, or whether the author has spent so much time ingesting AI-generated content that the tells have rubbed off, but this article has:

- Strange paragraph-lists with bolded first words. e.g. "The Cash Flow Mystery"

- The 'It's not just X; it's Y' meme: "Buying Groq wouldn't just [...], it could give them a chip that is actually [...]. It’s a supply chain hedge."

Tells like:

- "My personal read? NVIDIA is [...]"

- "[...]. Now I'm looking at Groq, [...]"

However, even if these parts were AI generated, it's simultaneously riddled with typos and weird phrases:

- "it looks like they are squeezing each other [sic] balls."

- Stylization of OpenAI as 'Openai'.

Not sure what to make of this low-quality prose.

Even if the conclusion is broadly correct, that doesn't mean the reasoning used to get there is consistent.

I do, at least, appreciate that the author was honest up-front with respect to use of Gemini and other AI tools.

Final grade: D+.

tzury•24m ago
The Burry short is just one data point, but the "facts we know" are piling up fast.

Here is a possible roadmap for the coming correction:

1. The Timeline: We are looking at a winter. A very dark and cold winter. Whether it hits before Christmas or mid-Q1 is a rounding error; the gap between valuations and fundamentals has widened enough to be physically uncomfortable.

The Burry thesis—focused on depreciation schedules and circular revenue—is likely just the mechanical trigger for a sentiment cascade.

2. The Big Players:

Google: Likely takes the smallest hit. A merger between DeepMind and Anthropic is not far-fetched (unless Satya goes all the way).

By consolidating the most capable models under one roof, Google insulates itself from the hardware crash better than anyone else.

OpenAI: They look "half naked." It is becoming impossible to ignore the leadership vacuum. It’s hard to find people who’ve worked closely with Altman who speak well of his integrity, and the exits of Sutskever, Schulman, and others tell the real story.

For a company at that valuation, leadership credibility isn’t a soft factor—it’s a structural risk.

3. The "Pre-Product" Unicorns: We are going to see a reality check for the ex-OpenAI, pre-product, multi-billion valuation labs like SSI and Thinking Machines.

These are prime candidates for "acquihres" once capital tightens. They are built on assumptions of infinite capital availability that are about to evaporate.

4. The Downstream Impact:

The second and third tier—specifically recent YC batches built on API wrappers and hype—will suffer the most from this catastrophic twister.

When the tide goes out, the "Yes" men who got carried away by the wave will be shouting the loudest, pretending they saw it coming all along

Very helpful, an AI comment analyzing an analysis of AI
jchw•10m ago
I don't believe your comment is just a direct dump out of an LLM's output, mainly because of the minor typo of "acquihires", but as much as I'd love to ignore superficial things and focus on the substance of a post, the LLM smells in this comment are genuinely too hard to ignore. And I don't just mean because there's em-dashes, I do that too. Specifically these patterns stink very strong of LLM fluff:

> leadership credibility isn’t a soft factor—it’s a structural risk.

> The Timeline/The Big Players/The "Pre-Product" Unicorns/The Downstream Impact

If you really just write like this entirely naturally then I feel bad, but unfortunately I think this writing style is just tainted.

cmiles8•17m ago
The circular funding is concerning, but more concerning are suggestions that supply might be vastly exceeding demand. Not that people don’t want chips but that the chip production now exceeds the ability to power them up and use them. The shortage is power and racks in data centers ready to go. Folks are running numbers suggesting there’s a bunched chips now just sitting around.

That, combined with some cooling from an AI hype bubble burst (see separate articles about companies missing quota as folks aren’t buying as much AI as the hype hoped) and there’s a potential ugly future where the headline demand plummets in top of idle chips waiting to be powered on. Suddenly the market is flooded with chips nobody wants.

jmole•9m ago
Isn't circular funding how the entire economy works?

I can see how you could make an argument that this particular ouroboros has an insufficient loop area to sustain itself, or more significantly, lacks connection to the rest of the economy, but money has to flow in circles/cycles or it doesn't work at all.

I don't see why. Graphcore bet on SRAM and that backfired because unless you go for insane wafer scale integration like Cerebras, you don't remotely get enough memory for modern LLMs. Graphcore's chip only got to 900MB (which is both a crazy amount and not remotely enough). They've pivoted to DRAM.

You could make an argument for buying Cerebras I guess, but even at 3x the price, DRAM is just so much more cost effective than SRAM I don't see how it can make any sense for LLMs.
