Does anybody know why some ETFs pay out such big dividend? TARK 21%

It's not a yield max garbage. It's Cathie Wood's ARKK x2. Different kind of garbage, hahaha. $69 , $17.70 dividend. It's not a mistake, ex-dividend dropped about that much.

Why such a big dividend? Where does it come from? Are they making that much extra money? on their swaps or what ever they use.
