Burry held $750M notional short position by end 2005, paid $100M in premiums while waiting.

By the end of 2005, he had already a 750 million notional position. Now, on top of having this massive position, he actually had to pay a $100 million in premium. So, imagine this is a crypto trade. You think that Hyperliquid is going to go down, so you start shorting it. And it doesn't go down yet, but as you've shorted it, you have to pay funding on the position. So, you're paying funding every day, every 24-hour period as you hold this huge short. So, it's costing you money and you still haven't been proven right yet. Well, imagine this on a macro scale. He's now building this short over years, holding it, and the market kept performing.
