Common questions about PLTR

What does the options flow on PLTR actually mean?

It is the money that changed hands in PLTR options on 2026-10-16: $186.2M paid for calls, $190.4M for puts. Premium is the better read than contract count, because a thousand cheap far-dated calls and one large near-dated block are not the same conviction, and only premium tells them apart.

Is heavy call buying in PLTR bullish?

Not by itself. 49% of PLTR's premium sat on the call side, and a good share of any day's call volume is someone hedging a short, closing a position, or a market maker managing inventory. Flow says where money went, never why. It is one input among several, which is how it is weighted on the desk.

What is the difference between volume and open interest on PLTR?

Volume is what traded today: 421877 calls and 370821 puts. Open interest is what is still on the book afterwards, currently 138k of calls against 113k of puts. Volume can spike and vanish the same day; open interest rising means positions were opened rather than closed.

What is dealer gamma exposure on PLTR?

It is the aggregate gamma the market makers who sold PLTR options are carrying. It matters because they hedge it, and that hedging is real buying and selling in the stock. As of 2026-10-16 it is positive.

What happens when PLTR gamma is positive versus negative?

Positive gamma means dealers sell into strength and buy weakness, which compresses the range and makes moves fade. Negative gamma means they do the opposite, selling weakness and buying strength, which extends moves. Same stock, opposite character, depending only on which side dealers are on.

Why do the sign flips matter more than the level?

Because the flip is when the behaviour changes. PLTR has flipped 10 times across the window shown here. A large positive number tells you little on its own; crossing zero tells you hedging flow just switched from working against the move to working with it.

Which members of Congress have traded PLTR?

10 distinct members appear in the disclosures for Palantir Technologies Inc., across 40 transactions, 26 of them purchases. The table above names each one with their chamber, the trade date and the date it was disclosed.

Why is there a gap between the trade date and the disclosure date on PLTR?

The STOCK Act gives members up to 45 days to file. The most recent PLTR entry here was traded 2026-07-17 and disclosed 2026-09-04. That lag is the law working as written, not evidence of anything, and it is the main reason this data is context rather than a signal.

Why are the amounts shown as ranges?

Because that is how they are filed. Members report a bracket, such as $1,001 to $15,000, never an exact figure. Anyone quoting a precise dollar amount for a congressional trade is estimating from the bracket.

Are insiders buying or selling PLTR?

Across the filings shown here, 0 buy-side and 5 sell-side transactions in Palantir Technologies Inc.. Each row names the insider, their title and the value, because a director's purchase and a CEO's scheduled sale are not the same event even when the dollar figure matches.

Does insider selling in PLTR mean something is wrong?

Usually not. Executives are paid in stock and sell for tax bills, houses and diversification, much of it through pre-scheduled 10b5-1 plans set months in advance. Selling is the normal state. It is the absence of buying, over long stretches, that says more than any single sale.

Why does insider buying carry more weight?

Because there is one reason to buy your own company's stock with your own money and many reasons to sell. A cluster of open-market purchases by several PLTR insiders in the same window is the version worth noticing; a single small buy near a proxy deadline is often optics.
