2008 financial crisis prophet bets against the AI bubble with potential $1 billion payout — Michael Burry reveals put options on Nvidia and Palantir
Contrarian stance against two of the biggest AI-fuelled stocks could be the pin that pops the bubble.
Scion Asset Management has disclosed that, as recently as September 30, it was betting big on the decline of AI-fuelled titans like Nvidia and Palantir. While we don’t often concern ourselves with stock market wrangling, this firm was founded and is still currently led by Michael J. Burry. The name may be familiar to moviegoers as the protagonist in The Big Short. In 2008, Burry famously predicted the seismic subprime mortgage crisis, cashing in on the ensuing financial crisis with a series of bold bets against the market.
Scion’s action, outlined today by Bloomberg, didn't come out of the blue. The founder’s personal Twitter/X account, Cassandra Unchained, forewarned that this financial strategy was unfolding last Friday – on Halloween.

As embedded above, Burry chilled those listening with his financial neo-Haiku. “Sometimes, we see bubbles. Sometimes, there is something to do about it. Sometimes, the only winning move is not to play.”
Sentiment regarding an AI bubble becoming ripe to burst has been growing in recent months as segment-related company values skyrocket. While many of these companies seem happy to invest billions and billions to chase the AI dream, it remains unclear how they will eventually monetize and claw back this expenditure.
News of dizzying circular deals has also raised suspicions. Recently, there have been multiple circular-feeling deals involving Nvidia at the center, like this one with xAI. Moreover, AMD and OpenAI recently signed a cozy GPU deal with stock involved.

Cassandra Unchained reminded followers of these circular relationships, just a few hours ago.
What has actually happened?
According to reports in the financial press, Scion bought options in Nvidia and Palantir in recent weeks. These options have a notional value of over $1 billion, so Burry stands to win big if they pay out. However, not all Scion’s shorts are in AI-exposed businesses, as the filings show bets were also placed against the likes of Halliburton Co. and Pfizer Inc. These positions were valid as of September 30, so it is possible that Burry could have sold or adjusted these positions since then.

Of course, we should also be careful not to jump to conclusions, as Burry might simply be using his ‘Cassandra’ reputation for short-term gains, not for altruistically warning folks of impending disaster...
Today has seen Nvidia shares dip as low as $200, with the price currently down 2.2%.
Palantir is feeling harder hit, with shares dipping as low as $185. It has recovered somewhat at the time of writing, but remains 6.7% down.
Reeling under the significant impact of short sellers this morning, Palantir CEO Alex Karp has been on CNBC, dismissing Burry's talk of an AI bubble as "batsh*t crazy" in a clearly panicked tone. See embed below at 2m8s.
Nvidia: the AI gold rush shovel maker
We think Nvidia may be less vulnerable to an AI bubble bursting than many pure AI plays. Remember, it has been in the enviable position of profiting from making shovels during this gold rush. The worst hit, when the day comes, will surely be those AI firms trading mostly on the promise of ‘jam tomorrow.’

JamesJones44 Just short the QQQ once the santa rally is done in late December. Worked like a charm for the .com bubble in 1999 (QQQ was brand new back then). There are AI ETFs out there as well, but there not a liquid which could be an issue for those with low risk appetites.Reply -
joeer77 Scare article. Sorry I don't believe it. The S&P 500, 200 day and 50 day moving averages show strong divergence and thus a strong economy. Same for Nvidia. No one has seen what a 5 trillion dollar company like Nvidia can do to the market. The signs were there in 2008. I don't see them this time.Reply -

The signs aren't financial, though. AI is very much in "emperor's new clothes" territory now with everyone saying how marvelous it is, but we all know that it's being adopted indiscriminately by companies wanting to save some money regardless of the impact on their customers and staff. Once they realize this is a bad move, like losing customers because of it, they'll drop it like a stone and that's when the crash will start. Either that or AGI will be developed first and then who knows what'll happen?joeer77 said:Scare article. Sorry I don't believe it.

There are some positive signs, but there are also negative signs. The market still has a lot of confidence overall, but when that confidence fades drastically, the ball is likely already too big as it rolls downhill to stop (full recession and not just a market correction phase). Even GDP is largely propped up by AI spending; GDP without AI spending is thought to be barely over 0% according to some estimates. -

I think you are missing a big part of the picture here. Unlike with the 2008 crash that you mention had signs, this one won't have signs until it already crashes. 2008 was a financial crisis due to bad lending on bad physical properties to people with poor or no credit. The initially banks didn't care because they were selling these bad investments off to other people/corporations and were simply happy with the processing fees and finders fees they were collecting on the deals. These were bad investments because it was assuming that the physical property prices would continue to hold value and/or continue to rise, but there was a bubble in the market for properties in a large part due to the fact that these banks and other financial institutions were offering these loans to so many people who traditionally would not otherwise have received a loan or mortgage approval for such a large amount at any time previously in the history of the country. This let to an artificial increase in the number of buyers looking for homes and properties, which also lead to an increase "house flip" sales because the market could not keep pace with the demand (and as such prices kept rising)... All it took was for the housing bubble to start to pop due to many of the sub-prime loans not being able to be paid back, causing the start of foreclosures, leading to a drop in the prices of homes as the foreclosures caused the prices to begin to fall, leading to many speculators in the realestate market (i.e. house flippers) to also stop payment on their loans as the properties were now worth less than the loans they had taken on them, so best to simply let the banks take them back since it was cheaper to give up the property than it would be to attempt to sell it at a loss....joeer77 said:Scare article.

Anyway, if you look at all that, there are plenty of warning signs to that problem. This AI issue won't really come with warning signs. There are lots of companies investing millions and even billions of dollars in AI, in terms of purchasing hardware, building datacenters, leasing power plants, obtaining researchers and developers from both academia and competitors, sunk costs of training initial AI models, purchasing access rights to training materials, scraping the internet for free training materials, creating interfaces for people to interact with a trained AI model, etc... All these costs on the hopes that there may be a product that can be sold at some point in the future. There currently really isn't much of a commercial product yet. Sure there are some things that are being sold, but the sales are barely enough to pay for the electricity that is being used to train and run the AI model, let alone all the other cost factors. At some point, the investors are going to want to see actual returns. This is much more like the .com bubble than the 2008 bubble. The warning signs of it ending will happen too late to do anything about it and it will have already burst. It is rampant massive spending and investing with no clear end product in sight. Massive amount of investment capital is being thrown at any company that suddenly sticks "AI" in its goals or business statement (just like the .com days of cash thrown at all kinds of places just because they said they were doing it in the internet, or cyperspace...). It starts to pop when some of the smaller firms attempt to get their next series of funding and no one throws money at them like it grew on trees in their backyard... But it is too late then, billions if not trillions will have been spent in almost every case with little to no monitizable product being build or delivered, and the only assets owned by the company will be now-depreciated super-high-end AI/ML computer servers that are 3-5 years old an not worth a penny on the dollar of their initial costs, and high priced leases on datacenters or multi-year aggrements with power companies to purchase utility power at a certain quantity for a certain rate for a set number of years... -

The stock is massively overinflated based on current demand. Not being able to sell to china and reports of companies having data centers worth of cards they can’t use doesn’t look like a profitable outcome for Nvidiajoeer77 said:Scare article.

American2021 Once the people's champion leaves office, the LISEP economic metric will climb up to between 35% to 40% over the next decade as the tariffs fall away and mass offshoring to foreign nations/mass outsourcing to foreign firms/mass in-sourcing of foreign replacement labor resumes as before; only this time with a rapid expansion of next generation AI/automation/robotics as well. It will be interesting to see if the general population realizes they've been materially dealt out of their own nation's domestic labor market by an argentocracy. As C. S. Lewis wrote, "Experience: that most brutal of teachers. But you learn, my God do you learn." If they do, the bubble is going to pop not simply deflate over time after it reaches its peak as normally happens when invention/innovation inflates a sector.Reply -

Trying to figure out how other companies owning data centers worth of cards that they can't use causes a problem to Nvidia. Nvidia already made the sale, they already achieved their profits from that hardware. It is the company that has them sitting in their data centers that needs to have figured out a way to receive a profit from their investment in purchasing those cards in the first place. Nvidia already put the money in their own pockets and their investor's pockets, and it is on the other companies to figure out how to get a return on their own investment, as Nvidia already made their return...LordVile said:The stock is massively overinflated based on current demand.

The only downside to Nvidia would be if they have overcommitted future manufacturing and investments other sunk costs in manufacturing lines and product lines that they can't either pivot to other products/markets and still cover their own costs. There may also be some lost future sales due to a possible glut of GPU cards in the secondary markets from companies that bought cards that they can not figure out how to use them and sell to other companies that do not mind taking the risk on second-hand products (not all business will take that risk and will insist on buying new and/or ones that have proper warranty).
But that is really it. Nvidia already made it's money off those cards and chips, which is part of the reason the stock is up. Sure the stock may go down some if the market completely pops and Nvidia can no longer project future sales growth the same way it does now, but that is the normal risk to any investor on any stock as the future is not known...
