VIX options let you trade the stock market’s implied volatility directly, not a stock, not an index fund, but the level of fear and uncertainty itself. That makes them one of the most distinctive instruments available to retail traders and one of the most commonly misunderstood.
The biggest mistake traders make is assuming VIX options work like SPY or AAPL options. They do not. The underlying is different, the settlement is different, and the behavior near expiration is different in ways that have caught experienced traders off guard. This guide covers the structural quirks you need to understand before placing your first VIX options trade.
Key Takeaways
- VIX options are European-style (no early exercise) and cash-settled to a special settlement value called VRO, not the spot VIX print at expiration.
- The underlying for VIX options is a VIX futures contract, not the spot VIX index itself. VIX can spike to 40 while near-month VIX calls price only a 25 move because futures are in contango.
- Long VIX calls are the cleanest portfolio hedge against a volatility spike. Short VIX positions require significant margin and are only suitable for accounts with substantial capital and explicit approval.
- tastytrade and Interactive Brokers both support VIX options. Robinhood and Webull do not offer VIX options.
- VIX options expire on Wednesday mornings, not Friday. Check your expiration dates carefully.
What VIX Actually Measures
VIX is the CBOE Volatility Index, a real-time measure of expected 30-day implied volatility for the S&P 500. It is calculated from the prices of a wide range of SPX options expiring in the next 30 days, specifically from the options market itself rather than from historical price moves. When options buyers are paying up for protection, VIX rises. When they are relaxed, VIX falls.
VIX is often called the “fear gauge” and that is a reasonable shorthand, but the precise meaning matters when you are trading it: VIX is implied volatility, not realized volatility. It represents what the market expects volatility to be over the next 30 days, not what volatility has been. That distinction affects how you should think about VIX options pricing.
Why VIX Options Are Structurally Different
The Underlying Is a Futures Contract, Not Spot VIX
This is the most important fact about VIX options and the one that trips up traders who are accustomed to equity options. When you buy a VIX call, you are not buying an option on the spot VIX index. You are buying an option on the VIX futures contract that corresponds to the same expiration.
VIX futures trade on their own curve, and that curve is usually in contango: the futures for future months are priced higher than spot VIX, because the market expects volatility to revert toward the long-term average of roughly 20. This means that even when spot VIX is sitting at 14 (calm market), the one-month VIX futures might be priced at 16 or 17. A VIX call option expiring in 30 days is priced off the futures at 16, not the spot at 14.
The practical consequence: if you buy VIX calls expecting them to pay off when VIX spikes from 14 to 20, and the futures were already at 17, your calls only need to see a move to 20 on the futures side, not a 6-point move from spot. When the futures curve steepens or flattens, your call pricing changes even if spot VIX stays constant.
European Style and VRO Settlement
VIX options are European-style, meaning they can only be exercised at expiration, not before. Unlike American-style equity options where early exercise is always a possibility, VIX options cannot be assigned early. This eliminates one category of risk that options sellers on individual stocks must manage, but it also means you cannot capture intrinsic value early if you want out of a long position.
At expiration, VIX options do not settle to the closing VIX print. They settle to VRO, the CBOE Volatility Index Settlement Value, which is calculated using the opening prices of the relevant SPX options on the expiration Wednesday morning. VRO is determined by a special opening auction, and it frequently differs from both the prior day’s VIX close and the first-print VIX at 9:30 AM.
This matters in practice: a VIX call that appears to be in-the-money at 4 PM Tuesday based on the closing VIX can settle out-of-the-money at the Wednesday VRO if early market conditions pull the settlement value lower. Traders holding VIX options through expiration should check VRO, not VIX, to determine their settlement value.
Wednesday Morning Expiration
Standard VIX options expire on Wednesday mornings, not Friday afternoons like most equity options. Monthly VIX options expire on the Wednesday that is 30 days before the third Friday of the following month. There are also weekly VIX options for more active traders. If you are accustomed to Friday expirations and you hold VIX options over a weekend expecting to manage them Monday, you may be closer to expiration than you think.
VIX Term Structure and Contango Decay
The VIX futures curve typically slopes upward, meaning later-month contracts are priced higher than near-month contracts. This is called contango, and it creates a persistent headwind for long VIX positions held over time.
If spot VIX is at 15 and the one-month VIX futures are at 17, you are effectively paying a premium above spot when you buy near-month VIX calls. As expiration approaches and futures converge toward the settlement value, that premium erodes if volatility stays flat. This is why “buy VIX calls and wait for a spike” is a costlier strategy than it appears: the contango decay works against long positions in quiet markets.
The opposite occurs during volatility spikes: when markets sell off sharply, VIX futures can flip into backwardation (near-month futures priced above later months), which dramatically increases the value of near-term VIX calls. This is the payoff moment that VIX call holders are positioned for.
Three Practical Strategies for Retail Traders
1. Long VIX Calls as Portfolio Hedge
The most straightforward retail use case for VIX options is as a portfolio hedge. Because VIX tends to spike sharply when equities sell off (VIX and SPX are negatively correlated), long VIX calls can offset losses in a long equity portfolio during drawdowns.
A hypothetical example: a trader with a $100,000 equity portfolio buys two VIX call contracts at the 25 strike when VIX is at 16, paying $1.50 each ($300 total). If the S&P 500 drops 10% in a market correction and VIX spikes to 35, those calls could be worth $8-10 each, generating $1,600-$2,000 in gains to partially offset the portfolio drawdown. The hedge does not make money in calm markets and loses the $300 premium if VIX stays below 25, but that is the cost of insurance.
The sizing and strike selection depend on your portfolio and your risk tolerance. Strike selection above the current futures level (not spot VIX) keeps the hedge affordable. Buying far-dated VIX calls reduces contango decay but costs more premium. Shorter-dated calls are cheaper but expire sooner and require rolling.
2. VIX Put Spreads as Short-Volatility Income
When VIX is elevated (historically, any reading above 25-30 tends to mean-revert lower), selling VIX put spreads can generate income from the expected decline. A hypothetical bull put spread on VIX might sell the 25 put and buy the 20 put, collecting a net credit: if VIX stays above 25 at expiration, you keep the full credit.
This strategy is defined-risk (your maximum loss is the spread width minus the credit collected), which makes it accessible to traders without portfolio margin approval. The key requirement is that you have a view on VIX levels relative to the current futures price, not just spot VIX. Checking the VIX futures curve on your platform before placing the spread helps you set strikes relative to the true underlying.
VIX put spreads are not the same as naked short VIX positions. Naked short VIX exposure (short VIX futures or short VIX calls without a long offset) carries substantial risk in a volatility spike and is not appropriate for most retail accounts. Defined-risk spreads contain your downside.
3. VIX Calendar Spreads for Term Structure
When the VIX futures curve is steep in contango, a calendar spread, buying a later-month VIX call and selling a near-month VIX call at the same strike, can profit from the roll-down as the near-term contract expires and the longer-dated option holds its value or gains.
Calendar spreads on VIX require understanding the term structure at both expiration dates. Because VIX options are European-style with VRO settlement, the near-month position will settle to VRO at expiration regardless of what spot VIX does, which makes calendar management simpler than with American-style options where early exercise is a variable.
Where VIX Options Trade and Who Can Access Them
VIX options trade on the CBOE and are among the most liquid options in the world when the underlying is at an active level. Bid-ask spreads tighten during elevated volatility regimes and widen during quiet periods when open interest and volume thin out.

What VIX Options Are Not Suited For
VIX options are not a good vehicle for short-term directional bets on “VIX will go up this week.” The contango decay works against holders in calm markets, and the futures/spot divergence means your intuition about where VIX is heading may not match where the futures settle. Short-term VIX directional trades require precise knowledge of the term structure, not just the spot VIX reading.
VIX options are also not a replacement for equity put options on your individual positions. A long VIX call hedges against a general market volatility spike but does not protect against stock-specific risk (a company-specific earnings miss, for example). Portfolio-level hedges and position-level hedges serve different purposes.
Bottom Line
VIX options give retail traders direct access to market volatility as a tradeable asset, but only if you understand that the underlying is VIX futures, settlement is to VRO on Wednesday mornings, and European-style rules eliminate early exercise. Long VIX calls are the most practical retail application as a portfolio hedge, while defined-risk VIX put spreads offer a way to collect premium when volatility is elevated and expected to mean-revert. Naked short VIX exposure is not appropriate for most retail accounts.
Frequently Asked Questions
Q: Can I buy VIX calls to hedge my stock portfolio?
A: Yes. Long VIX calls are the simplest VIX options strategy for retail traders. Because VIX tends to spike when equities sell off, long VIX calls at an out-of-the-money strike can partially offset equity portfolio losses during a market drawdown. Size the hedge relative to your portfolio, and account for contango decay if you hold the calls for weeks or months without a volatility event occurring.
Q: Why is my VIX call losing money even though spot VIX is rising?
A: VIX options are priced off VIX futures, not spot VIX. If the futures curve is in steep contango and the spot VIX rise has not been matched by a similar move in the futures contract underlying your option’s expiration, your call may show little gain or even a loss. Check the VIX futures price for your specific expiration on your broker’s platform to understand the true underlying level.
Q: When do VIX options expire?
A: Standard VIX monthly options expire on Wednesday morning, not Friday. The specific date is the Wednesday that falls 30 days before the third Friday of the following calendar month. Weekly VIX options also exist and expire on Wednesday mornings. Always confirm your specific expiration date before holding a VIX position near expiry.
Q: Which brokers support VIX options for retail traders?
A: Interactive Brokers, tastytrade, and Charles Schwab (via thinkorswim) all support VIX options with standard options approval levels. Robinhood and Webull do not offer index options, including VIX. Fidelity’s Active Trader Pro also does not support VIX options trading for most retail accounts. Check current terms at your broker before placing your first VIX options trade.
Q: What is VRO and how is it different from VIX?
A: VRO is the CBOE Volatility Index Settlement Value, the official settlement price used to cash-settle VIX options at expiration. It is calculated using the opening transaction prices of the relevant SPX options on expiration Wednesday morning, not the closing VIX the prior Tuesday or the 9:30 AM spot VIX print. VRO and spot VIX often differ, sometimes significantly, in the first hour of trading on expiration day. Always use VRO, not spot VIX, to determine whether your expiring VIX options are in-the-money.
