Exposures are the assumed dealer book as of Oct 29, 2026, all expirations. Assumes dealers are long the calls and short the puts, a share p of open interest each - here 100% of open interest (the GEX page sets the share). A date without a stored exposure is a gap; a value marked * is partial, averaged over fewer days, or may include contracts expiring that day or of an unreadable expiration: its reason is printed beside it.

As of Oct 29, 2026, Palantir Technologies Inc. (PLTR) has 3.4M total contracts outstanding across all expirations. Put/call OI ratio is 1.12 (balanced positioning). Open interest reflects accumulated positions from prior sessions; persistent growth indicates sustained directional or hedging interest, while sharp drops typically mean post-expiration clean-up.

How PLTR open interest history Data Feeds Strategy Selection

Strategy selection on Palantir Technologies Inc. options does not derive from any single metric in isolation. The open interest history view above sits inside a broader read: ATM IV currently sits at 64.6% and the assumed dealer book's GEX is positive, so its hedging is mean-reverting. Combine the open interest history data here with the volatility-skew surface, gamma exposure, max-pain level, and upcoming-events calendar to build a positioning thesis. Risk-defined structures (credit spreads, debit spreads, iron condors) are usually safer than naked positions while the regime is uncertain; the data on this page anchors the inputs but does not by itself constitute a trade thesis.

How to read the PLTR open-interest data

The open-interest time-series below tracks the total Palantir Technologies Inc. options inventory outstanding day by day. OI is a stock measure - the cumulative position count - so trends flag accumulating or distributing positioning. Current put/call ratio is 0.67, roughly balanced. Total call OI of 1.6M versus put OI of 1.8M gives a put/call OI ratio of 1.12 - structurally a slower-moving signal than the volume-based ratio.

PLTR flow vs positioning

Volume tells you what flows happened today; OI tells you what positions accumulated. Both can move in opposite directions: rising volume with falling OI means contracts are being closed (covering); rising volume with rising OI means new positions are being opened. The combination matters more than either alone for reading sentiment. With the assumed dealer book's GEX positive, large OI clusters are more likely to act as price magnets through expiration cycles where real dealers are positioned like the book.

Using PLTR OI/volume data alongside other surfaces

Per-strike OI is the input to the assumed dealer book's GEX: the strike with the most call gamma is the call wall, where the book's hedging sells into a rally, and the strike with the most put gamma the put wall, where hedging the book's short puts sells as price falls toward it. The gamma-exposure page combines this distribution with the book's assumption (dealers long the calls, short the puts) to project hedge flow. Volume cross-checks recent positioning shifts in the chain that haven't yet shown up in cumulative OI. Pair both with the term-structure view on the volatility page to determine whether the activity is concentrated in near-dated event hedging or longer-dated structural positioning. Front-month expiration for PLTR sits at 29 days, so near-dated volume currently dominates the flow reading.

What does PLTR open interest tell traders?

Persistent OI growth indicates sustained directional or hedging interest; sharp drops typically mean post-expiration position cleanup. Heavy OI concentrations at specific strikes concentrate the assumed dealer book's gamma there: it is long gamma at call-heavy strikes, where its hedging leans against moves, and short gamma at put-heavy ones, where its hedging can extend them. Comparing today's volume to standing OI separates opening flow from closing flow.
