On November 11, 2026, TechFlow reported, citing The Defiant, that two Buildix snapshots showed the open-interest value of two Anthropic pre-listing perpetual contracts on Hyperliquid totaling more than $311 million. The two readings were 25 minutes apart and were not a synchronized full-market total.
Trade.xyz’s ANT contract was recorded at $109.37 million in open interest, about 30% above the $84.04 million The Defiant logged on November 10. EntropyIO’s ANTH contract was recorded at $201.81 million.
The contracts are not quoted in the same units. ANT is referenced to one share of Anthropic Class A stock. On ANTH, each price point represents $1 billion of company valuation.
The reported open-interest value does not represent purchases of Anthropic stock or financing received by the company. It is a figure for derivative positioning on Hyperliquid, drawn from two separate venue snapshots rather than a single market-wide reading.
