- US equity markets are evolving towards 23-hour trading, five days a week, leaving 53 hours each week without a national quotation, creating a pricing gap for continuous markets.
- Pyth covers over 220 US equities on a 24/5 basis, while Hyperliquid utilizes discovery bounds and Pyth-constructed indices to support weekend pricing.
- HIP-3 markets have seen over $540 billion in volume, with 407,000 traders and more than $4 billion in open interest.
As traditional US equity markets extend their hours, the need for continuous pricing becomes increasingly important. Hyperliquid and Pyth are at the forefront of addressing this gap in the market, ensuring that asset prices remain available even when traditional exchanges are closed. Over $540 billion has been traded across real-world asset markets hosted on Hyperliquid and priced by Pyth. The challenge lies in balancing the extended hours of traditional markets with the continuous operation of onchain venues. The key question now is how pricing should be determined when the underlying exchange is closed and no official market price is available.
Hyperliquid and Pyth: Bridging the 53-hour gap
Pyth provides coverage for more than 220 US equities on a 24/5 basis, sourcing price data from entities involved in price formation, including overnight sources like Blue Ocean and alternative trading systems. However, once Friday trading concludes, the underlying market becomes inaccessible. This is where Hyperliquid’s weekend mechanism plays a crucial role. Through HIP-3, independent teams can launch perpetual futures markets, select their pricing sources, and establish risk parameters, while Hyperliquid offers the necessary exchange infrastructure, order book, and liquidity engine to sustain trading activity.
During periods without external pricing, Hyperliquid employs discovery bounds developed by Trade[XYZ], a market leader accounting for 99% of current HIP-3 volume. The most recent external price serves as an anchor, restricting trading within defined ranges until the anchor resets. Additionally, Pyth offers 24/7 constructed indices for individual US equities when official exchange prices are unavailable. Together, this model extends the visibility of pricing, sets boundaries for price discovery when necessary, and establishes a reference point in the absence of direct market observation. This framework ensures that equity-linked markets have a defendable price throughout the entire week.
The impact of these developments is significant. HIP-3 markets have witnessed over $540 billion in cumulative volume, with 407,000 traders participating and more than $4 billion in open interest, largely driven by Pyth’s pricing feeds. The ongoing discussion now revolves around the feasibility of continuous real-world asset trading and the regulatory challenges it presents. Douro Labs and the Hyperliquid Policy Center have urged the SEC to acknowledge qualified independent price sources when consolidated quotations are unavailable, while a separate FINRA filing advocates for updated best-execution guidelines. The 53-hour gap is not just a market structure issue but also a regulatory litmus test.
