Triple Witching 2026 Dates: How ES, SPX, and SPY Are Affected

Reviewed by the SPXtoSPY Editorial Team

Every quarter, the same date lands on the calendar and triggers a predictable surge in volume, a spike in intraday volatility, and a cascade of expiration-driven program trades. Triple witching is not unpredictable chaos — it's a scheduled confluence of expiration mechanics you can plan around. If you're holding ES futures, SPX options, or SPY positions heading into a quarter-end Friday, understanding what's happening in each instrument prevents expensive surprises.

This guide covers the 2026 triple witching dates, what each instrument does on that day, and the practical playbook for futures holders and options traders who need to navigate the session cleanly.

2026 Triple Witching Dates at a Glance

Triple witching falls on the third Friday of March, June, September, and December. These are the same months that mark the quarterly ES futures expiration cycle — which is not a coincidence. The CBOE deliberately aligns index option expirations with CME futures expirations so that settlement prices are derived from the same opening auction.

Note that June 19, 2026 is also Juneteenth (a federal holiday). Markets are open — Juneteenth falls on a Friday in 2026 and the NYSE and CME observe it on the holiday date itself, but since it falls on a trading day this year, standard equity and futures markets may have modified settlement procedures. Check with your broker for any holiday-adjacent settlement nuances specific to June 2026.

What "Triple Witching" Actually Means

The three instruments that expire simultaneously are:

1. Stock index futures — ES (E-mini S&P 500), NQ (E-mini Nasdaq), RTY (E-mini Russell 2000), YM (E-mini Dow). These quarterly contracts reach final settlement on triple witching Friday morning via the Special Opening Quotation (SOQ).
2. Stock index options — SPX, NDX, RUT monthly options expiring that Friday. These AM-settled options (SPX standard, RUT standard) also settle against the SOQ. Note: SPX weekly options (XSP-style) can expire PM-settled; the monthly cycle is what drives the witching convergence.
3. Individual equity options — All monthly-cycle equity options expiring that Friday. Thousands of contracts across individual names, all expiring at market close.

What's sometimes called quadruple witching adds single-stock futures — but those are no longer actively traded on US exchanges, so the modern event is effectively the original three instruments. The "quadruple" label persists in financial media as a legacy term.

ES Futures on Triple Witching Day

The ES quarterly front-month contract reaches final settlement on triple witching Friday. The settlement price is the Special Opening Quotation (SOQ) of the S&P 500 — a computation based on the opening prices of all 500 S&P 500 component stocks on that Friday morning, not the Friday close and not the Thursday ES settle.

The SOQ process works like this: at 9:30 AM ET, the 500 individual S&P 500 stocks begin opening via their own opening auction procedures. As each stock prints its first trade, that price is captured. The index level calculated from those prices becomes the SOQ — the final settlement value for both the ES quarterly contract and AM-settled SPX options. If any stocks haven't opened by around 10:00 AM, the CBOE uses the previous close for the laggard and proceeds.

The practical implication: you cannot replicate or trade the SOQ in real time. By the time you know what it is, the ES position has already settled at that price. This is the primary reason most professional traders roll their front-month position well before the event.

The Roll Window: Don't Wait Until Triple Witching

The standard institutional roll window opens 8–10 calendar days before the expiration Friday. For the four 2026 dates, that means:

Rolling later than this — say, on the Wednesday or Thursday of expiration week — means you're competing against institutional programs that are also rolling, often into wider calendar spreads and reduced front-month liquidity. A spread that normally costs 0.25 points can widen to 0.50–1.00 points in the final two sessions. At $50 per ES point, that's $25–$50 per contract per side in avoidable friction.

Roll as a single calendar spread order (sell front month, buy next quarter as one instrument) rather than legging — entering the two legs separately costs you two half-spreads plus market impact instead of one calendar spread bid/ask.

SPX Options on Triple Witching Day

The SPX standard monthly options (typically the third Friday of each month) are AM-settled. This means they stop trading at Thursday's close and settle Friday morning against the SOQ — the same number that settles ES. This alignment between SPX options and ES futures settlement is deliberate: both reference the same underlying index value at the same point in time, preventing arbitrage gaps between the instruments.

If you're holding SPX puts or calls through expiration, be aware that you cannot exit them on Friday morning before settlement — they've already stopped trading. The P&L is locked in at the SOQ. If that number surprises you (the SOQ can diverge from Thursday's ES close by a meaningful amount on high-volatility days), there's nothing you can do post-close Thursday.

The practical rules:

• Close or roll SPX monthly positions by Thursday's close at the latest.
• The SPX weeklies (Wednesday and Friday) that are not the standard monthly are PM-settled — those expire at Friday's close and trade all day Friday. Check your option series carefully before assuming.
• On triple witching Fridays, SPX volume surges as market makers delta-hedge expiring positions. Expect elevated moves in the first and last 30 minutes of the session.

SPY on Triple Witching Day

SPY options behave differently from SPX on triple witching Friday because SPY is a PM-settled instrument. SPY monthly options expire at the close of trading on the third Friday — the same day, but hours later than the SOQ event that settles ES and SPX. SPY is American-style and can be exercised at any point before expiration, but the vast majority of options expire at 4:00 PM ET.

What this creates is a window of activity on triple witching Fridays:

1. Morning (9:30–10:30 AM): SOQ prints and settles ES futures and SPX monthly options. Index rebalancing programs from major ETFs fire their large basket orders near the open. SPY typically gaps and then reverts as the rebalancing activity completes.
2. Midday (11 AM–3 PM): Relatively calmer. The morning programs have cleared. Remaining SPY positions are still open.
3. Final hour (3–4 PM): The "witching hour." SPY option market makers aggressively delta-hedge expiring positions. Gamma is at maximum for near-the-money strikes. A $1 move in SPY can flip thousands of contracts from in-the-money to out-of-the-money (or vice versa), forcing rapid hedging adjustments. Volume in the final 15 minutes routinely exceeds 10–20% of the day's total.

If you're holding SPY positions into triple witching Friday, the volatility is concentrated in those two windows — not spread evenly through the day. Midday is typically the quietest entry or exit point.

Index Rebalancing on Triple Witching Day

A layer of activity beyond pure expiration mechanics: major index funds and ETFs that track the S&P 500, Nasdaq 100, and Russell 2000 often execute their quarterly rebalancing on triple witching Friday. When the index methodology calls for adding or removing a constituent, or adjusting float-adjusted weights, the fund must buy and sell shares to match the new index composition.

The Russell 2000 reconstitution is the most dramatic annual example (typically June), but smaller quarterly rebalances happen every triple witching. These rebalancing basket trades are often telegraphed in advance — the index methodology publishes anticipated adds/deletes weeks ahead — and traders front-run them in the days leading up to the event, often creating a "buy the rumor, sell the news" dynamic on the day itself.

For ES and SPY holders, this means pre-triple-witching price moves in individual large-cap names can be exaggerated relative to what the macro environment would otherwise imply. Index-level moves around the open on rebalancing days often revert once the program trades are absorbed.

How to Use the Converter Around Triple Witching

Triple witching is a natural inflection point for reviewing your cross-instrument positions. After the ES rolls to the next quarter, the conversion ratio between ES and SPY updates slightly — because the new front-month ES price includes the forward cost of carry rather than the settled cash price. If you're using ES as a hedge against SPY shares, recalculate the hedge ratio after each roll.

At SPX 5,600, the rough conversion: ES notional is $50 × 5,600 = $280,000. SPY trades near $560 (at the ~1/10th ratio). You'd need approximately 500 SPY shares to match one ES contract. After a triple witching roll, if the new front-month ES opens 20 points above the settled value due to carry, your ES-to-SPY conversion reflects that new level — not the settled SOQ. Use the converter to get the current ratio rather than assuming last quarter's math holds.
