Whether it's pennies in front of a steamroller will depend on the entry price, EV, time left to resolution and many other variables.
Though I agree it's bad math, even if 70% resolve to no, there's a high variance among all of them, and to know whether it's a good bet or not... you have to do your DD on that particular market. Even if you follow the Kelly criterion, randomly choosing bets will probably tank your bankroll sooner or later.

No, all these variables cancel out.
If you were picking and choosing, yes. But this approach is basically betting no on all the markets.
The textbook explanation of this is the central limit theorem, proving this mathematically is a bit more involved for power-law systems like this but it’s empirically valid.
