Kain Warwick emphasized that deep liquidity is fundamental to establishing trust in prediction markets, arguing that price signals are only reliable when backed by significant capital. He noted that minimal bets capable of moving market odds produce untrustworthy information, whereas substantial financial commitment validates the signal's authenticity. Warwick illustrated this principle by contrasting a five-dollar bet that shifts ETH price predictions above $3,000 against a billion-dollar position achieving the same outcome. According to Warwick, only when massive capital is required to move a prediction can the resulting market signal be considered credible and reflective of genuine probability.
