Hyperliquid gets first builder-deployed HIP-4 outcome DEX as OUT deploys on the framework

Hyperliquid has received its first reported builder-deployed HIP-4 outcome exchange, after a project operating under the name OUT completed deployment through the network’s permissionless market framework, according to on-chain records.

A transaction visible on Hyperliquid’s block explorer confirms that an outcome DEX registered under the name OUT deployed through the HIP-4 framework. The deployment is a milestone for the protocol’s ambitions to become a platform where independent teams can launch their own prediction and outcome markets on top of shared infrastructure. The transaction confirms the deployment itself, but does not show whether OUT’s markets have opened for live trading, and no separate announcement or verifiable website detailing its markets or liquidity was available at the time of writing.

## What HIP-4 actually does

HIP-4 is Hyperliquid’s framework for outcome markets, first introduced on testnet in February and activated on mainnet on May 2. Under the system, approved deployers can create outcome markets without seeking validator approval for every individual contract, provided each market follows a template the validator set has previously approved.

Templates define the basic form of a contract, its available results and how it settles. Once validators approve one, a deployer can reuse the same structure to spin up separate markets that meet its conditions. A YES/NO template allows traders to bet between two possible results, while multi-result templates can cover questions with several possible answers, although Hyperliquid’s main HIP-4 documentation says multi-outcome support was not included in the initial mainnet release and will arrive in stages.

There is an important caveat about OUT specifically. Hyperliquid’s deployer documentation, updated on August 13, currently labels permissionless HIP-4 deployer actions as testnet-only, meaning OUT’s deployment should not be described as a confirmed permissionless mainnet launch without additional evidence.

The permissionless deployment plan has real costs attached. According to a July report, market operators must stake 500,000 HYPE to participate, and validators can slash deployers for incorrect or delayed settlement. Separate stakes are required for HIP-3 and HIP-4 operations, since one HYPE allocation cannot support both deployments simultaneously, creating a high entry barrier for independent teams seeking to run both perpetual and outcome exchanges.

## Outcome contracts without leverage or liquidations

HIP-4 products differ fundamentally from the perpetual futures that made Hyperliquid famous. Outcome contracts are fully collateralized, settle within a fixed range at expiration, and carry no funding rate, no borrowed funds and no liquidation process.

For a binary market, a YES token settles at 1 if the stated event occurs and at 0 if it does not, with the NO side receiving the opposite result. A trader buying YES at 0.60 earns 0.40 per contract if the event happens, while the purchase price represents the maximum possible loss. The structure removes the existential risk of leveraged trading: your worst case is known the moment you open the position.

Hyperliquid describes HIP-4 as a general-purpose tool rather than a system limited to conventional prediction questions. Its fixed-range structure can also support bounded options-style products where maximum payout and loss are known upfront.

Trading takes place through HyperCore, the network’s on-chain order-book engine, which also runs Hyperliquid’s spot, perpetual and HIP-3 builder-deployed markets. Fees are not charged when an outcome position opens, though charges can apply when closing, burning or settling, and the protocol waived outcome-market fees during its initial testing period.

## From Bitcoin binaries to CPI prints

Hyperliquid’s first mainnet HIP-4 product was a recurring Bitcoin binary contract that settled each day at 06:00 UTC against the BTC mark price published through HyperCore, providing an objective reference for deciding whether YES or NO tokens received the payout.

The network later expanded beyond crypto prices. In May, a US CPI contract allowed traders to position on the annual inflation rate reported by the Bureau of Labor Statistics, offering three possible results: below 4.3 percent, exactly 4.3 percent, or above 4.3 percent. It used USDC as collateral and settled from the official BLS release.

Validator-settled markets have since covered Federal Reserve decisions and sporting events. Galaxy Research reported that validators can publish approved off-chain results through regular network operations, reducing reliance on a separate oracle provider, and that HIP-4 recorded 2.38 million USD in 24-hour Bitcoin outcome volume by its 25th day, roughly a fifth of the combined Bitcoin prediction volume across major platforms.

## A stepping stone for the Hyperliquid ecosystem

OUT’s arrival, whatever its eventual traction, signals that the HIP-4 machinery works end to end: a third party has used the framework to deploy its own outcome exchange on the network. If mainnet permissionless deployment follows the testnet phase as planned, Hyperliquid could host a proliferation of builder-deployed markets, each staked and slashable, competing for traders on the same order-book infrastructure.

The stakes are meaningful beyond one network. Prediction markets have become one of crypto’s fastest-growing sectors, and the ability to permissionlessly launch outcome markets with fully collateralized, liquidation-free contracts is a direct challenge to both centralized prediction platforms and oracle-dependent decentralized rivals. The next few months will show whether OUT is a one-off deployment or the first of many.
