Latest available snapshot — open interest settled on 2026-08-31. This is a dated positioning read, not a live number. The static page is rebuilt nightly from the latest upstream chain available; intraday volume does not move open interest until the next settlement.
What did the 2026-08-31 snapshot show?
F carried 547,430 open option contracts across the 7 listed expirations inside 45 days. The front expiration, 2026-09-04, held 55,046 of them — 17,245 puts against 37,801 calls, a put/call ratio of 0.46. The heaviest single call strike (the call wall) sat at $14, +0.4% from the last price, and the heaviest put strike (the put wall) at $14, +0.4% away. Open interest counts open contracts, not intent: every contract has a buyer and a seller.
Heaviest strikes — 2026-09-04
The ten strikes holding the most combined open interest for the front expiration, among strikes within 15% of the max pain level (the window our nightly pipeline reports).

How concentrated is F open interest?
In the 2026-08-31 snapshot, the wall-to-wall strike gap for F was 0.0% of the settled last price and belongs to the headline 2026-09-04 expiration. The expiration-share figures use all 547,430 contracts across the 7 listed expirations inside 45 days. We do not publish a top-ten-strike share for F: its reported window contains only 9 strikes within 15% of max pain, so a top-ten share would mostly measure the width of that window. Read the wall distance as a same-expiration strike gap, and the expiration shares as how the reported chain's contracts were distributed across listed expirations. Chain-wide, the 2026-09-18 expiration was the largest bucket, holding 72.5% of the 547,430 contracts counted across the 45-day window. Every figure is derived from open-interest counts — what open interest measures, and how it differs from volume explains how those counts are created, destroyed and settled once a day. A crowded strike means many contracts exist there; it does not mean price is drawn to it or repelled by it. Before assigning meaning to either wall, read our guide to what call and put walls can — and cannot — tell you; it explains why a crowded strike is a concentration marker, not support, resistance or a price target.

Common questions
How much F open interest was outstanding in the latest snapshot?
Using open interest settled at the close on 2026-08-31, F carried 547,430 option contracts across the 7 listed expirations inside 45 days. The front expiration, 2026-09-04, held 55,046 of them: 17,245 puts and 37,801 calls.
What is open interest?
Open interest is the number of option contracts that exist and have not yet been closed, exercised or expired. It is not trading volume: a contract that changes hands ten times in a day still counts once. Every contract has a buyer and a seller, so open interest says how many positions are open, not which side anyone is on.
What are the F call wall and put wall?
They are simply the strikes holding the most call and put open interest for an expiration — $14 and $14 respectively in this snapshot. The count says where contracts are concentrated; whether price respects those levels is a separate empirical question the count itself cannot answer. The guide at quantdata.uk/guides/call-wall-put-wall explains how to read them without treating them as support or resistance.
Is F open interest concentrated in a few strikes?
We do not publish a top-ten-strike share for F: the window we report — strikes within 15% of max pain — spans only 9 strikes at this price, so the figure would measure the window rather than F. The put wall sat at $14 and the call wall at $14, 0.0% apart measured against the last price. Chain-wide, 2026-09-18 was the heaviest of the 7 listed expirations at 72.5% of all 547,430 contracts. These are contract counts. They show concentration, not whether price will be attracted to or repelled by a strike.
When does F open interest update?
The clearing house settles open interest once per trading day, after the close. This page is rebuilt nightly from that end-of-day file, so no figure here — or anywhere — is a live intraday open-interest reading.
