Do Most Options Expire Worthless? The Data Behind the 90% Myth

No — the claim that most options expire worthless is a myth. Only about 30-35% of options contracts actually expire worthless (Cboe); roughly 55-60% are closed out before expiration and only ~10% are exercised (Cboe/OCC). The viral "90%" figure counts contracts that were not exercised — not contracts that died worthless. Research and education only, not financial advice.

The numbers, in one table

Every option contract meets one of three fates: it is closed (bought or sold back before expiry), it is exercised, or it is held to expiration and expires worthless. The clearing data that tracks these outcomes is public — the Options Clearing Corporation (OCC) records exercises, and Cboe publishes the broader disposition breakdown. Here is what the fractions actually look like.

Where the "90% expire worthless" myth comes from

You have almost certainly heard it: "90% of options expire worthless, so sell premium and collect." It is one of the most repeated lines in retail trading, and it is a misreading of a real number. The real statistic is that roughly 90% of contracts are not exercised (Cboe / OCC). "Not exercised" and "expired worthless" are not the same thing — and the gap between them is enormous.

The reason: the ~55-60% of contracts that get closed before expiration (Cboe) are also "not exercised." A trader who buys a call and sells it back for a profit two days later never exercised it — yet that contract was not worthless; it was cashed out. Fold those closed contracts in with the truly-expired-worthless ones and you reach ~90% "not exercised." Strip the closed trades back out and only ~30-35% of contracts actually expire worthless (Cboe). The myth survives because "90%" makes a better sales pitch than "about a third."

Why "expires worthless" is not the same as "someone lost everything"

Even the honest ~30-35% figure gets over-read. "Expires worthless" is a statement about the contract at 4:00 p.m. on expiration day — not about whether anyone profited. Two things it does not tell you:

• It does not mean the buyer lost 100%. Buyers frequently close early — for a gain, or to salvage part of the premium before decay finishes the job. A contract can be sold at a profit and still the remaining open interest expires worthless in someone else's hands. The ~55-60% close-rate (Cboe) is direct evidence that positions rarely ride to zero untouched.
• It does not mean the seller profited. An option can expire worthless while the seller still lost money — for example, a covered call that expires worthless because the stock collapsed far below the strike. The seller kept the premium but ate a much larger loss on shares. "Expired worthless" describes the option, not the trade around it.

So the worthless-expiration rate is a fact about contract disposition, not a scoreboard of winners and losers. Anyone quoting it as proof that "option sellers win 90% of the time" is stacking two separate errors on top of each other.

How to read these numbers

These are pooled, market-wide shares across all listed options — deep in-the-money LEAPS and lottery-ticket weeklies get averaged together. Your own outcomes depend entirely on which options you trade: far out-of-the-money short-dated contracts expire worthless far more often than the ~30-35% average, while in-the-money contracts rarely do. The aggregate is useful for debunking a myth; it is useless for predicting a single position. And none of it changes the base rate that matters most: options are high-risk instruments, and a long option can lose 100% of its premium.
