You'd think the timing should reflect the typical terms of loans and loan volumes - so that sounds plausible. When the default rate of those loans begins to creep up and become notable to investors, then people will get edgy.

I just hope it comes before our much loved and overpaid layers of incompetent management have destroyed all their manual production processes and replaced them with snake oil. If not a general economic downturn might start well before the ai bubble bursts.

How the hell did he do a long term bet against the market? Aren't shorts short-term and they're forced to pay after a set period of time? Even the inverse indexes will steadily make your money simply vanish.

We may have to wait for another three years.

Which is also a clue that he isn't short selling.

There are two ways of making money when a stock goes down. One is to sell the stock short. The other is to buy a put option.

A short sale is extremely risky. Say the shares are at $50 and you think they're going to go down, so you sell 1000 shares you don't own (short selling) and agree to buy them back by some date in the future. If you're right and the stock tanks to $20, you can buy the shares and pocket $30,000. But, if the stock doesn't sink, you might have to buy the shares for $60 each, so you lose $10 per stock, or $10,000. If there are tons of people shorting the stock, you can get a short squeeze, where everybody needs to buy shares to close out their short position, and because everybody needs to buy, the stock price rockets up, so you get people having to buy a stock that used to be $50 for $200, leading to $150,000 in losses for a 1000 share short where the maximum possible gain was only $50,000.

An option is much safer. There you're buying the option to sell the shares at a certain price at some time in the future. Say you think a stock is going to crash. It's currently trading at $50/share. You can buy 1000 put options at a strike price of $40 with a date 1 month in the future. It will cost you something to buy those options, say $1 per share, so $1000. If the stock goes up or stays at $50, your bet didn't work out. You don't have to sell the shares, you just tear up the options contract. You're out whatever you paid for the option, say $1000 here. But, say the stock tanks and it's now at $20/share. Now your bet did pay off. You can buy 1000 shares at $20 each for $20,000, then immediately exercise your option and sell them for $40,000, netting you $20,000. With put options the upside is significantly smaller, but the potential downside is tiny. It's just the cost of the options.

Someone predicting a crash within 3 years isn't going to short sell the shares. Between now and then the shares could continue to rise for a while, and they'd be on the hook for a huge payout in that case. If they buy options the down side is much smaller. They may have to re-buy new options a bunch of times. But in the worst case they just have to let the options expire unused and eat whatever cost they paid for them.

For the coming AI crash, I don't think it will be very soon. I think there will be a crash. But, I think the government will try to keep the bubble from bursting. Too much of the US economy is now invested in AI. So, even under Biden, or Harris, or Obama they'd try to prevent a catastrophic crash by using taxpayer money to prevent the most damaging bubble burst. With Trump, there's going to be even more government interference in the market. His backers are crypto bros. They're the ones making him billions on his meme coins. They bankrolled JD Vance's political career. If they demand that he rescues their failing companies, he'll do it. And, since the GOP does whatever Trump wants, they'll just fork over literal trillions in taxpayer dollars to keep things from crashing. But, eventually there will have to be a crash, because there's just not a sustainable business model in any of this, at least not at anything like the current scale.

It is interesting that stocks began going down though. Whether it continues, we should see.

A short is not only a bet on a direction but also a timing issue. You need to know roughly how long (time) to keep the option.
