- US equity markets are transitioning towards 23-hour, five-day trading, leaving 53 hours each week without a national quotation, resulting in 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 facilitate weekend pricing.
- HIP-3 markets have seen over $540 billion in volume, with more than 407,000 traders and over $4 billion in open interest.
As US equity markets move towards extended trading hours, the need for continuous pricing becomes evident. Hyperliquid and Pyth are addressing this gap in the market by ensuring that asset prices remain accessible even during non-traditional trading hours. Real-world asset markets on Hyperliquid, priced by Pyth, have witnessed over $540 billion in trading volume. The challenge lies in aligning traditional market hours with the round-the-clock operations of onchain venues. The crucial question now is how pricing should be managed when official market prices are unavailable.
Hyperliquid and Pyth: Bridging the 53-hour gap
Pyth provides price data for more than 220 US equities on a 24/5 basis, sourcing information from firms involved in price formation, including overnight sources like Blue Ocean and other alternative trading systems. However, once traditional markets close on Fridays, the underlying market data disappears. Here is where Hyperliquid’s weekend mechanism comes into play. Through HIP-3, independent teams can launch perpetual futures markets, select pricing sources, and establish risk parameters, while Hyperliquid offers the necessary exchange infrastructure, order book, and liquidity engine to keep trading active.
During periods with no external pricing, Hyperliquid employs discovery bounds developed by Trade[XYZ], whose markets contribute to 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 in the absence of exchange-provided prices. This approach extends pricing visibility, limits price discovery when necessary, and establishes a reference point when direct observation is lacking. This model ensures that equity-linked markets have a reliable price throughout the entire week.
The magnitude of this development is significant. HIP-3 markets have generated over $540 billion in cumulative volume, involving more than 407,000 traders and exceeding $4 billion in open interest, with Pyth feeds pricing the majority of this activity. The focus is now shifting from the feasibility of continuous real-world asset trading to whether regulatory frameworks can keep pace. Douro Labs and Hyperliquid Policy Center have urged the SEC to acknowledge qualified independent price sources in the absence of consolidated quotations, while a separate FINRA submission advocates for updated best-execution guidelines. The 53-hour gap is evolving from a market structure challenge to a regulatory litmus test.
