Anthropic (ANT) is expected to list in about two weeks, while premarket contracts across platforms imply a market capitalization of about $1.8 trillion against an anticipated valuation of $1.75 trillion. An unidentified whale has opened a $25.43 million short position in Anthropic premarket contracts on Hyperliquid and continues to add to it, according to on-chain analyst Ember. Short selling seeks to profit from a decline in the contract's value, and the whale's activity suggests skepticism about Anthropic's pricing ahead of its debut.
