Could not find much infos about it specifically, but looking at the page from LeverageShares itself (the company issuing the product), it lists a price of 0.00$, last refreshed on the 5th of November.
If you look at other products, they are always refreshed daily on their website.
I am guessing Peloton had a loss bigger than 33% on that day, hence the 3x product lost 100% of its value; and I think most stock exchange might freeze trading before delisting securities that reach 0.00.
EDIT: Indeed on the 5th of November, Peloton lost 35.3% from previous close, hence the 3x products lost 100% of their value.
Furthermore, most stock exchanges in the world would delist shares reaching 0.00
Leveraged products will always carry a risk of becoming worthless, regardless of their shape. As a rule of thumb, 2x leverage allow for a loss of 50%, while 3x only have room for a 33.3% loss.
