Buildix Now Supports Hyperliquid HIP-4 Outcome Markets

When Hyperliquid launched HIP-4 on May 8, 2026, it added a third asset class to HyperCore alongside spot and perpetuals. Outcome markets are fully collateralized binary contracts that pay one dollar to the winning side and zero to the losing side at settlement. The first builder to ship them is Outcomexyz, currently running daily Bitcoin price binaries that ask whether BTC will close above a specific strike at the daily settlement at 06:00 UTC.

Buildix is one of the first analytics platforms to support HIP-4 from day one. As of today the integration is live on the screener and includes everything we believe a serious trader needs to evaluate these markets: live implied probability tracking, fair value modeling against spot, divergence detection, builder accuracy track records, and Telegram alerts for the events that matter most.

The screener now has a third tab next to Hyperliquid perps and HIP-3 markets, dedicated to HIP-4 outcomes. Each row shows the question being asked, the underlying asset and strike, the implied probability inferred from the order book, the fair probability computed by our pricing model, the divergence between the two, the builder, and the time to resolution. Click into any market and you land in a deep view with a Recharts visualization that tracks all three metrics over time.

The fair probability is computed using a lognormal Black-Scholes-style model that takes the current spot price, the strike, the time to expiry, and a volatility assumption. For binary contracts of the form will BTC close above X this gives a closed-form probability via the standard normal cumulative distribution function. Our current volatility assumption is hardcoded at 0.5 annualized, which is a reasonable fallback for Bitcoin daily binaries but will be replaced in the next release with realized 7-day volatility computed from candle data. The chart explicitly displays the volatility assumption with a small badge so traders can see at a glance which calibration is in effect.

The divergence between implied and fair is the metric that surfaces actionable edge. When the market prices a YES outcome at 88 percent but the model says fair value is closer to 70 percent, that 18-percentage-point gap is potentially mispriced supply that a sophisticated trader can interrogate further. We tier the divergence threshold by subscription level. Trader plan triggers alerts above 15 percentage points, Pro at 10, Whale at 5. The thresholds reflect how much noise tolerance each tier accepts before being notified.

Around the 60-minute mark before resolution the fair probability calculator returns null by design. The lognormal model becomes numerically unstable as time to expiry approaches zero, so rather than ship visibly bad numbers we cut the calculation cleanly at the boundary. The chart renders this as a visible gap in the gray dashed line, which is a feature not a bug. During the final hour, only the implied probability and spot price are tracked, and the only alerts that fire are the resolution timer notifications at 60 and 15 minutes out.

The Telegram alert system covers five distinct conditions. Extreme high probability above 90 percent and extreme low below 10 percent fire when the market is pricing close to certainty in either direction. Large divergence fires when the gap between implied and fair exceeds the user-configurable threshold for their tier. Resolution one hour and resolution fifteen minutes are countdown reminders so traders can prepare to close or hedge before the binary settles. Each alert carries the underlying, the strike, the current implied probability, the fair value if available, the divergence in percentage points, the time to resolution, and a deep link back into the Buildix interface.

Settlement detection runs on a 60-second cron and writes a permanent record into our resolutions table for every binary that closes. Each record captures the final implied probability, the spot price at resolution, whether the market was settled as YES or NO, and which builder published the question. The dedicated resolutions tracker page aggregates these records into per-builder accuracy statistics including raw correct rate, confidence-weighted accuracy that puts more weight on confident predictions, volume-weighted accuracy, and average final spread from the 50 percent line. Traders can filter by builder, underlying asset, and resolution window to see how well each prediction venue is calibrating its order book against actual outcomes.

A note on coverage. HIP-4 supports two question types, priceBinary and priceBucket. PriceBinary asks a single yes-or-no question against one strike and currently powers all the active Outcomexyz daily markets. PriceBucket asks which of several price ranges the underlying will fall into at expiry, with named outcomes plus a fallback bucket for prices outside the defined ranges. Buildix supports priceBinary out of the box. PriceBucket support is on the roadmap for the next release and requires extending the fair value model to a multi-bin distribution and the order-book parser to track all sides of the question simultaneously. Until then priceBucket markets are filtered out and noted in the screener tab counter.

For builders publishing HIP-4 markets, Outcomexyz is currently the dominant venue but Hydromancer has announced an integration in progress and there are credible rumors of two or three additional venues onboarding in the coming weeks. As more builders publish, the resolutions tracker becomes more valuable as a comparison tool. A builder with consistently miscalibrated implied probabilities is one whose markets are systematically mispriced, which is exactly the kind of signal that benefits informed counterparty trading.

Buildix HIP-4 support is available across all tiers with feature gating that scales with subscription level. Free and Trial tiers see the screener and the deep view but cannot set up alerts. Starter unlocks basic alerts for resolution timers. Trader through Whale unlock the divergence threshold alerts and the resolutions tracker with finer-grained tiers as described above. Whale tier additionally unlocks CSV export of historical probability data for backtesting and the upcoming AI Strategy Advisor that interprets the market context using a bring-your-own-key LLM provider.

We expect HIP-4 to become a meaningful part of crypto derivatives within months as more builders publish and as institutional traders look for collateralized binary exposure that does not require trusting a centralized prediction market. Buildix is positioned to be the analytics layer for that adoption curve. Active subscribers can find the new tab live at the screener at buildix.trade/screener with the HIP-4 Outcomes filter selected. Builders interested in seeing their accuracy track record on the platform can reach us at hello@buildix.trade.
