PANews reported on June 16th that, according to Laevitas, the HIP-3 builder layer on Hyperliquid is currently almost entirely monopolized by Tradexyz, which holds approximately $2.871 billion in open positions, accounting for about 97% of the total network open positions of $2.959 billion. All other builder DEXs combined hold less than $88 million, including approximately $35 million in Dreamcash, $22 million in HyENA, and $19 million in Ventures. The report points out that although a market for long-tail builder-built perpetual contracts has emerged on-chain, in terms of actual capital volume, it remains at the "tail end" relative to Tradexyz.
