Are markets always better than surveys?
No. They answer different questions and often complement each other.

Prediction markets vs surveys
A survey tells you what people say; a market price tells you what money thinks the odds are. Those are not the same number.

The short version
A survey aggregates opinions. A market aggregates opinions that people are willing to lose money on, which tends to discipline the wishful thinking out. Neither is better; they answer different questions. The mistake is reading a sentiment poll as if it were a probability, and sizing a position on it.
Why it matters
Confusing sentiment with probability is how people talk themselves into bad trades. 68% of fans thinking the deal closes is not a 68% chance the deal closes. Knowing what a number is actually measuring, opinion or odds, is the foundation everything else sits on.
Same topic, different number
