Aren't prediction markets meant to ascertain the likelihood
of whether, and if so even perhaps when, such events as
Trump and Ivanka perishing in a joint accident, might
actually occur?

As opposed to the certainty of a market evaluating
the Sun rising this Sunday or not, what is the expected
margin of error a strong well established market might
bring to such unusually difficult predictions as above?
