Every number in this post comes from OptionsBell's own options tape for August 2026 - 21 trading sessions, every logged call and put premium summed by underlying. No estimates, no third-party feed. Here is where the largest and most lopsided positioning actually landed.

Where the money was: the raw premium leaders

By total call premium, the month belonged to the usual mega-caps, but the ordering is the interesting part. Micron (MU) topped our tape with roughly $8.1B in call premium, ahead of NVDA (~$7.7B) and TSLA (~$7.3B). Then the pattern breaks: Microsoft (MSFT) logged ~$5.2B in calls against just ~$0.75B in puts - a call-to-put premium ratio near 7-to-1, by far the most one-sided book among the giants.

Meta (META) is the mirror image. It was the only name in the top tier that ran put-heavy, ~$2.9B of puts against ~$1.8B of calls. When the biggest names all lean one way and one leans the other, that one is the story worth a second look.

The real skew lives outside the mega-caps

Raw size favors the names everyone already watches. Ratio tells you where conviction was concentrated. Filtering to names with at least $50M of total premium, the most call-skewed books in August were not tech at all:

NextEra (NEE): ~$1.0B in call premium against just $3M in puts - a 311-to-1 skew.
Rio Tinto (RIO): 272-to-1 calls over puts.
Marathon Petroleum (MPC) and Phillips 66 (PSX): 151-to-1 and 134-to-1 - a whole energy-refining cluster leaning the same direction.
Johnson & Johnson (JNJ): ~$971M of calls at 108-to-1, unusual for a name that usually trades like a bond.
Chevron (CVX): the heavyweight of the group at ~$1.26B of call premium, 71-to-1.

One energy-and-defensives call cluster this consistent across separate tickers is the kind of thing a price chart will not show you for weeks.

And where the fear was

The put side was even more extreme at the top. Avis (CAR) logged ~$1.5B in put premium against $1M in calls - a 1,772-to-1 put skew, the single most one-sided book on our tape all month. Lululemon (LULU) was close behind at ~$2.4B of puts, 582-to-1. AppLovin (APP) carried ~$1.4B of puts, and Roblox (RBLX) ran 36-to-1 to the downside.

A 1,772-to-1 put skew is not a hedge. Somebody was paying, in size, for a specific downside outcome inside a specific window. Whether they were right is a different question - but the positioning was unmistakable.

How to read a recap like this

None of these are buy or sell signals. They are a map of where leveraged, time-bound conviction concentrated last month. The useful move is to ask, for each cluster: what catalyst sits inside the expiry window, and who benefits if the strike pays off? The refiners and NEE point at energy; CAR and LULU point at consumer names with events ahead. The tape framed the questions in August. September's charts will answer them.
