Anthropic pre-market contracts: $311 million in open interest, but a thin price anchor

On November 11, 2026, BlockBeats reported that open interest in two Anthropic pre-market perpetual contracts on Hyperliquid exceeded $311 million combined. Trade.xyz’s ANT contract accounted for $109.37 million, up about 30% from $84.04 million on November 10. EntropyIO’s ANTH contract accounted for $201.81 million.

BlockBeats also reported that the pre-market perpetual contracts had risen more than 10% over the preceding eight hours and were trading at a roughly 37% premium to what it described as the upper end of an IPO offering range. The brief report did not establish that range or explain how it was determined. The premium is therefore a reported comparison, not a verified valuation benchmark.

The figures document substantial positioning in the contracts at the time of the report. They do not, on their own, show what Anthropic shares would be worth in an IPO.
