Hyperliquid launched the first US macro events market using HIP 4 outcome contracts, allowing traders to bet USDC on the May 2026 CPI on an annual basis in a fully collateralized, no-filter format that is settled on June 10 outside of official Bureau of Labor Statistics data.
summary
- The new CPI market uses HIP 4 outcome contracts settled in the BLS May 2026 release of the CPI on an annual basis.
- The contracts are trading as limited odds in USDC, with early volume around $3,000 and open interest near $5,000.
- Outcome markets sit alongside perpetual currencies under a unified margin system, blending crypto speed with macro trading events
HIP 4 is an upgrade of the Hyperliquid Protocol that adds “outcome contracts” to L1, a native primitive for prediction style and options markets as fully collateralized, dated, leverage-risk-free, and liquidation-risk-free products.
On May 2, the protocol activated HIP 4 on the mainnet, and MEXC reported that the initial deployment included recurring daily Bitcoin price binaries that recorded more than 6.05 million contracts and nearly 4,000 unique traders on the first day, capturing about 0.7 percent of the global prediction market volume.
How Does Hyperliquid’s CPI Score Market Work?
The new CPI market expands this template from native cryptocurrency prices to US macro data.
According to HIP 4 coverage and outcome trading, each contract represents a discrete event that eventually settles to 0 or 1 based on whether a pre-specified condition is met, with prices between 0 and 1 prior to the decision reflecting the market’s implied probability of a ‘yes’ outcome.
For the May CPI market on an annualized basis, traders effectively buy or sell segments of the distribution of the twelve-month change in the CPI as reported by the Bureau of Labor Statistics on June 10, 2026, with the tick values and brackets specified in the market specifications and all adjustments associated with the official BLS release.
Unlike perpetual contracts, HIP 4’s final contracts are fully collateralized upon entry: Hyperliquid’s documentation emphasizes that there is “no leverage, no liquidation,” and that the buyer’s maximum loss is the registered capital, while payouts are fixed at expiration based on the outcome of the event, just like a binary option.
Importantly, end contracts run directly on HyperCore and share the same unified margin account as perpetual contracts, so traders can deploy bridged USDH or USDC at once and spread those collaterals across perps, spot and event markets without siled balances.
In early CPI trading, the odds clustered in a balanced range, with order books showing odds of 34% to 43% across major categories and total trading volume of just over $3,000, with open interest approaching $5,000 – a small amount in absolute terms, but consistent with a new listing in a completely new product line.
Why CPI Markets Matter for Super Liquid Prediction Bars and Cryptocurrencies
The CPI list is not an isolated experience; It is part of a broader drive for transformation Excess fluid From a pure DEX exchange to a full-fledged derivatives site that can host prediction markets natively across crypto, macro and sports.
Binance’s explanation about HIP 4 notes that the upgrade “brings native prediction markets to Hyperliquid,” with outcome contracts designed to trade election results, sporting events, Bitcoin price thresholds, and “whether specific conditions have been met before a certain point in time,” all with fixed expiry and no risk of liquidation.
Unrestricted and MEXC both Highlight Competitive angle: By running outcome markets in the same core engine as Perps, with a unified margin calculation and low fees, Hyperliquid is clearly being targeted. Difficult Off-chain forecasting places like Polymarket on UX, capital efficiency and product breadth.
Aggregate inflation is the natural first goal.
Market forecasts for May and June confirm that the CPI remains the most important US data point for risk assets, with the latest consensus pointing to annualized readings of 3.3% to 3.7% and traders are closely watching for signs that energy-driven price pressures are taking hold.
By listing the CPI results market on an annual basis, Hyperliquid essentially allows existing Perp traders to express this aggregate supply directly into the same interface where they actually trade BTC, ETH, and underlying trades, rather than routing through an external prediction protocol or central broker.
In practical terms, this means that a single margin pool of USDH or USDC can now support a book of positions such as long BTC, short ETH, and holding “CPI above 3.7 percent” results, and all risks are managed by a single engine – bringing more trading-style cross-products to the native cryptocurrency chain.
If volumes and participation increase from the current few thousand dollars in CPI bets to millions, the launch could mark the beginning of a more serious migration of macro prediction flow to L1 derivatives platforms, blurring the line between DEXs and on-chain prediction markets and pulling the risk of future events — from inflation prints to elections — directly into crypto collateral stacks.
