As of May 29, 2026, Zillow Group, Inc. Class A (ZG) at $35.59 has an ATM IV of 59.3%, implying a 30-day one-standard-deviation range of approximately ±$6.05. IV rank is 41.6% (near its 1-year median). IV percentile is 75.0%. The 25-delta skew is +0.030: upside tail priced richer than downside, biasing probability mass above spot. Under lognormal assumptions roughly 68% of outcomes fall within ±1σ and 95% within ±2σ; risk-neutral probability analysis refines this by extracting the market-implied distribution directly from options prices, capturing the fat tails that real markets exhibit.
How ZG probability analysis Data Feeds Strategy Selection
Strategy selection on Zillow Group, Inc. Class A options does not derive from any single metric in isolation. The probability analysis view above sits inside a broader read: ATM IV currently sits at 59.3% and dealer gamma exposure is negative, so dealer hedging amplifies directional moves. Combine the probability analysis data here with the volatility-skew surface, dealer-gamma exposure, max-pain level, and upcoming-events calendar to build a positioning thesis. Risk-defined structures (credit spreads, debit spreads, iron condors) are usually safer than naked positions while the regime is uncertain; the data on this page anchors the inputs but does not by itself constitute a trade thesis.
How to read the ZG probability distribution
The probability cone above is the option-market-implied distribution of where Zillow Group, Inc. Class A spot could end up at expiration. It's derived from the implied-volatility surface via a risk-neutral pricing transformation, not from historical realized returns. With ATM IV at 59.3% and spot at $35.59, the 1σ band is approximately ±20.5% over a 30-day horizon. Recent realized HV-20 of 30.9% runs 28.4 vol points below the current implied, suggesting the chain is pricing more dispersion than the underlying has been delivering.
ZG risk-neutral vs real-world probabilities
The probabilities derived from option prices reflect the market's risk-adjusted view, not the realized statistical distribution. Risk-neutral probabilities include the equity risk premium and skew preferences priced into options, so they tend to overstate tail probability and understate upside drift relative to actually-realized outcomes. For probability-of-touch calculations and assignment-risk modeling, risk-neutral is the right benchmark. For position-sizing your own conviction, blend with realized-volatility-based statistics from the HV columns.
Trading the ZG distribution
Probability-driven strategies aim to capture mispricings between the implied distribution and your own probability assessment. Premium-selling structures (credit spreads, iron condors, cash-secured puts) profit when the implied distribution overprices tail probability relative to realized; premium-buying (debit spreads, long calls/puts, long straddles) profits in the reverse. Always pair probability-driven strategy selection with a stop loss or wing-defined risk - the implied distribution is a snapshot, and regime shifts can invalidate it intraday.

Frequently asked ZG probability analysis questions
- What is the ZG 30-day expected price range?
- As of May 29, 2026, with ZG at $35.59 and ATM IV at 59.3%, the implied 30-day one-standard-deviation range is approximately ±$6.05, or about $29.54 to $41.64.
- What does ZG risk-neutral density tell us?
- Risk-neutral density is the probability distribution of future ZG price implied by listed option prices. Extracted via Breeden-Litzenberger (twice-differentiating the call price function with respect to strike), it represents the pricing kernel rather than the real-world probability of outcomes. Persistent skew or fat-tail features in the density reflect how the market is pricing tail risk.
- How does ZG ATM IV translate to a probability range?
- ATM IV is annualized; multiplying by sqrt(t/365) scales it to the chosen tenor. Under lognormal assumptions, the resulting standard deviation defines the ±1σ band that contains roughly 68% of outcomes, ±2σ for 95%. Empirical equity returns have fatter tails than log-normal, so the implied tail probabilities under-state realized tail frequency in stressed regimes.
