ETH Becomes New Anchor for Secure Predictive Markets Growth

Protocols like Polymarket's prediction markets are scaling fast with ~$9B in 2024 and over $20B in 2025. However, oracle security is not keeping up.

Validators earn 80% of yield (~3%) on deposited ETH and voting weight is quadratic, making it costly to manipulate votes.
