If by 'collapse' you really mean a 50%+ fall, timing is not going to make or break you by any means.
If Anthropic is going to crash 50% or more at some unknown time in the next two years, and you have foreknowledge of this, you can easily make a massive profit by placing a bet weekly. The odds are VERY long per week, so on each losing bet you only lose a tiny amount, but on your winning week you will more than make up for it.
Timing is, as a general rule, important. In the particular case we're discussing, the odds of a 50% swing are so low that you can tolerate being VERY wrong on the timing if you are correct on the swing.
idk, if "prediction markets" remain a real thing, there should probably be some requirement for previous experience in options-adjacent markets to ensure people actually understand the economics of time-valued positions.
It's possible to be correct that the AI companies have no future, but not be able to time the exact month they collapse.
