Permissionless deployment triples HIP-4 trading volume, leaving permissioned listings as the main constraint

According to the author, permissionless deployment on August 29 lifted HIP-4 volume from a $545,000 August average to $1.97 million by August 31, with Outcome holding 85% of the last 24 hours, aided by a $1 million trade-to-earn rebate program. Hyperliquid's unified accounts let binaries hedge perpetuals on the same mark, unlike Kalshi or Polymarket. Sports is seen as the biggest upside—$189.5 million traded during the World Cup—but requires a validator vote, while US access constraints, not deployment, remain binding.
