XSP options, also called Mini-SPX options, are index options contracts on the S&P 500 that are 1/10th the notional size of standard SPX options. XSP is cash-settled, European-style, and qualifies for Section 1256 tax treatment — the same structural advantages as SPX, but accessible to accounts under $25,000.
What Is XSP?
XSP is the ticker for the Mini-SPX options contract, listed on the CBOE. The underlying tracks the same S&P 500 index as SPX, but each XSP contract represents 1/10th the notional exposure.
At an S&P 500 level of 5,500:
- One SPX option has a notional value of $550,000 per contract
- One XSP option has a notional value of $55,000 per contract
- A $5-wide iron condor spread on SPX requires ~$5,000 in buying power reduction
- A $5-wide iron condor spread on XSP requires ~$500 in buying power reduction
This size difference is why XSP is useful for smaller accounts. The strategy mechanics are identical — only the dollar amounts change.
Key Structural Features of XSP
| Feature | XSP (Mini-SPX) | SPX | SPY |
|---|---|---|---|
| Underlying | S&P 500 Index | S&P 500 Index | S&P 500 ETF |
| Contract Multiplier | $100 | $100 | $100 |
| Notional Size | 1/10th SPX | Full size | ~1/10th SPX |
| Settlement | Cash | Cash | Shares of SPY |
| Exercise Style | European | European | American |
| Section 1256 Tax | Yes | Yes | No |
| Liquidity | Moderate | Very deep | Very deep |
Cash Settlement Explained
When an XSP iron condor expires, it settles based on the final calculated value of the S&P 500 index. No ETF shares are delivered. This means:
- No early assignment risk (European-style exercise prevents this)
- No need to close the position before expiration solely to avoid assignment
- Settlement is clean — you receive or pay cash based on where the index closed
By contrast, SPY options (American-style) can be assigned early, and at expiration they deliver shares of the SPY ETF rather than cash.
The 60/40 Tax Benefit
XSP, like SPX, qualifies as a Section 1256 contract. Under US tax law, 60% of net gains from Section 1256 contracts are treated as long-term capital gains and 40% as short-term, regardless of how long the position was held. This blended rate is lower than the ordinary income rate most traders would pay on short-term stock options gains.
For a trader generating $10,000 per year in iron condor income, the tax difference between Section 1256 treatment and standard short-term rates can be several thousand dollars annually, depending on the trader's bracket.
XSP vs. SPY: Which Is Better for Iron Condors?
This question comes up frequently because both products track the S&P 500 at a similar notional size.
SPY advantages: Deeper liquidity, tighter bid-ask spreads in absolute terms, easier to fill multi-leg orders during volatile markets.
XSP advantages: European exercise eliminates early assignment risk entirely. Section 1256 tax treatment. Cash settlement removes the ETF share delivery complication.
For traders who prioritize tax efficiency and cleaner settlement mechanics, XSP is worth the slightly wider spreads. For traders who prioritize fill quality and execution simplicity, SPY is easier to work with in practice.
Who Should Use XSP for Iron Condors?
XSP makes sense for:
- Accounts between $2,000 and $20,000 that want SPX structural benefits without the capital requirements
- Traders who want to scale up gradually from small positions
- Tax-aware investors who prefer the 60/40 treatment over standard short-term rates
- Traders learning iron condor mechanics before committing to full SPX contracts
It is less suitable for:
- Very large accounts, where SPX provides better liquidity and tighter fills
- Traders who do not trade frequently enough for the tax treatment to matter meaningfully

Frequently Asked Questions
Is XSP the same as the Mini-SPX? Yes. XSP is the ticker symbol for the Mini-SPX options contract listed by CBOE. The terms "XSP" and "Mini-SPX" refer to the same product.
Where are XSP options traded? XSP options trade on the CBOE. They are listed under the XSP ticker and are available on most standard options brokerage platforms.
What are the trading hours for XSP? XSP trades during standard US market hours (9:30 AM to 4:00 PM ET). Extended hours trading exists but liquidity is thin outside of regular session hours.
Can you trade 0DTE iron condors on XSP? Yes. XSP has daily and weekly expirations available, which supports 0DTE strategies. However, 0DTE iron condors carry significant gamma risk in the final hours of trading and are not suitable for most systematic premium sellers. See what is a 0DTE options strategy for more context.
How does XSP compare to SPX for active traders? The main practical difference is liquidity. SPX has deeper markets, tighter fills, and more open interest across strikes. For a trader doing 5+ contracts per month, the difference is minor. For high-frequency or large-size traders, SPX's liquidity advantage becomes more meaningful.
Trading involves risk and losses can occur. Past performance does not guarantee future results. Options trading is not suitable for all investors. Only allocate capital you are comfortable risking.
