RESEARCH — THE FILING TAPE #13

Two of 83: Palantir's Superinvestors Hold Just 62,063 Shares. Its Insiders Have Bought Once.

October 9, 2026

GetCoattail Research — Palantir just reported second-quarter revenue up about 93%, raised full-year guidance to about $8.15 billion, and signed a sovereign-AI infrastructure partnership — and its stock has rebounded 61.8% since June 30 in our price file. We ran it through every filing lens we maintain. The broad register holds more than 1.4 billion shares. The concentrated registers barely register at all.

Start with the narrative. Palantir reported second-quarter 2026 revenue of $1.935 billion, up about 93% year over year, with earnings per share of $0.41 against a consensus estimate of $0.28, and raised full-year revenue guidance to $8.150 billion to $8.158 billion. On October 1 the company named Armada its inaugural Certified Modular Data Center Partner, extending its sovereign-AI operating system onto modular infrastructure that customers own and control. A social-media trending roundup on October 2 listed Palantir among the day's highest-volume names for search and sentiment, trading near its 52-week highs. A MarketBeat compilation on October 4 put the consensus analyst target at $195.33, only modestly above where the stock trades.

Now the filings. GetCoattail tracks the investors best placed to know any company: superinvestors, institutions, insiders, Congress, and 5% holders. For Palantir — the thirteenth Filing Tape audit, after IREN, CoreWeave, Micron, NVIDIA, Tesla, AMD, Apple, Amazon, Meta, Oracle, Dell and Bloom Energy — the gap is between the size of the story and the size of the concentrated positions filings can show.

Lens 1: the superinvestors — two holders, 62,063 shares in total

We track 83 large, mostly long-only managers whose 13F portfolios we collect directly from SEC EDGAR. As of June 30, 2026, two held Palantir in long common-stock positions — every reported row is a long position, with no option rows in the count. Their combined position is 62,063 shares worth $7,240,890. On a like-for-like pipeline basis the cohort was almost unchanged in the second quarter, moving from 62,313 shares at March 31 to 62,063 shares at June 30 — down 0.4%, a net decrease of 250 shares — in a quarter when the share price fell from $146.28 to $116.67 in our price file, down 20.2%. The pipeline and EDGAR-collection second-quarter totals agree exactly, at 62,063 shares.

The detail is short enough to print in full. Duan Yongping's H&H International Investment holds 60,000 shares — 96.7% of the cohort — worth $7,000,200, at a portfolio weight of 0.04%, and was unchanged in the quarter. David Katz's Matrix Asset Advisors holds 2,063 shares worth $240,690, at a weight of 0.02%, and cut 10.8%. Of the two holders, one was unchanged, one decreased, none increased, none was new. Palantir is one of the most discussed stocks in the market. In the tracked superinvestor register, it is a 60,000-share position and a 2,063-share position, neither of them above five-hundredths of one percent of its holder's portfolio.

Lens 2: institutions — fewer filers, 31.36% more shares

Zoom out to the whole 13F market and the register is large — and it moved in two directions at once. At June 30, 2026, 2,859 institutions reported positions in Palantir, down from 2,952 at March 31 — a 3.2% fall, a net loss of 93 filers — and 2,830 of them reported long positions. Yet reported share counts rose 31.36%, from 1,087,201,843 to 1,428,144,334 shares, with 1,859 filers entering and 1,952 exiting during the quarter. The dataset's reported aggregate value rose 4.0% to $194,186,682,052; the aggregate includes option rows, so we treat filer and share counts as the reliable series and the dollar figure as reported (see methodology). Read together, the two moves describe consolidation, not exit: fewer names on the register, holding substantially more shares in aggregate, in a quarter when the price fell 20.2%.

Lens 3: the 5% register — four filings, and a reporting name changes

Palantir's 5% register is thin relative to the company's size. Four SC 13D/G filings cover the stock — zero 13D filings and four 13G filings, from two reporters, the most recent filed April 30, 2026. Every filing belongs to one reporting family. The Vanguard Group reported 221,460,945 shares (10.15%) as of December 31, 2024, then 198,523,394 shares (8.82%) as of March 31, 2025, and then 0 shares (0.0%) as of March 13, 2026. Alongside that final row, a new reporter, Vanguard Capital Management, filed a 13G reporting 166,908,333 shares (7.28%) as of March 31, 2026 — 24.6% below the Vanguard Group's December 2024 row. We do not sum these rows and we do not call the zero an exit: two reporting names from the same index complex appear in sequence, and the filings themselves establish the sequence, not the reason for it. What the register does establish is narrower. No 13D — the filing an investor uses when it wants something from management — has appeared at all, and no second 5% reporter outside the Vanguard complex is on the register.

Lens 4: insiders — one purchase in the entire parsed record

The insider lens is the starkest in this audit. Across the entire parsed Form 4 record for Palantir (120 filings through October 2, 2026), there is exactly one open-market purchase transaction — 10,000 shares worth $1,161,400, by one buyer. In the last 90 days there were zero purchases, and in the last year there were zero purchases. Officer purchases are zero in every window: 90 days, one year, and the full record. The selling side is continuous and large. In the 90 days through October 2, 2026, insiders filed 14 reports covering 40 sale transactions totalling 768,027 shares and $124,574,870.43, by five sellers; counts here are transaction rows, and a single filing can carry many. Over the full year, sales total 318 transactions and $872,282,144.48 by nine sellers. Across the entire parsed record, sales total 729 transactions and $1,892,067,212.56 by 12 sellers, against that single $1,161,400 purchase. Some selling is mechanical — vesting, tax withholding and pre-arranged plans generate filings regardless of anyone's view — and we assign no motives. What the record establishes is narrower: through a period in which the stock rose to a market value of about $461.5 billion in our fundamentals file, insiders recorded one market purchase in total.

Lens 5: Congress — exactly balanced, three and three

Across the Senate and House transaction record we maintain (as of October 3, 2026), Palantir shows three purchase transactions and three sale transactions, by two members, one from each party. The House aggregate carries one member, a Democrat, with two purchases and three sales and a most recent purchase dated July 17, 2026. The Senate aggregate carries one member, a Republican, with one purchase and zero sales and a most recent purchase dated May 15, 2026. Congressional disclosures report value ranges rather than exact amounts, so we record direction only. A perfectly balanced congressional lens carries no directional signal either way — and in this series, where the lens is usually blank or one-sided, an exact tie is itself the finding.

Lens 6: short interest — down 64.1% from the peak, up 10.3% on the year

As of September 15, 2026 — the most recent FINRA settlement date — 60,184,903 Palantir shares were sold short, with days-to-cover of 2.24. That is 2.50% of the 2,402,897,000 shares outstanding in our fundamentals file (a share count as of June 30, 2026).

Short interest in Palantir, January 2021 to September 2026
Chart 2: Shares sold short in Palantir at each FINRA biweekly settlement, Jan 15, 2021 – Sep 15, 2026 (n = 137 settlements). The series peaked at 167,494,036 shares on Sep 29, 2023; the latest reading, 60,184,903 shares on Sep 15, 2026, is 64.1% below that peak and up 10.3% from 54,581,338 a year earlier.

Short interest peaked at 167,494,036 shares on September 29, 2023, and the latest reading is 64.1% below that peak. The shorter path is less settled: the latest reading is 10.3% above the 54,581,338 shares recorded a year earlier, the series low of 44,641,497 shares came on January 30, 2026, and over the last five settlements the borrow has fallen at each step but one, from 77,877,652 shares on July 15 to 60,184,903 on September 15. At 2.50% of the share count, the borrow is a small fraction of the register; its direction over the summer was down.

The gap, stated plainly

Palantir's filing record splits by register size, and this time the split is extreme. The broad register is enormous and consolidating: 2,859 filers holding 1,428,144,334 reported shares, up 31.36% in a quarter when the filer count fell 3.2% and the price fell 20.2%. The concentrated registers are close to blank. Two tracked superinvestors hold 62,063 shares between them — 96.7% of it in a single unchanged position weighted at 0.04% of its holder's portfolio. The 5% register contains one index complex, reporting under a new name, and no 13D at all. Insiders have recorded one purchase, ever, in the parsed record, against $1,892,067,212.56 of sales. Congress is tied, three purchases to three sales. Short interest is 2.50% of the share count. One plausible reading is that Palantir's register is carried by breadth — index and broad institutional machinery — while almost every register that requires a named, concentrated, discretionary decision shows either a token position or none. The record supports each clause separately; it does not say which register is right.

What would change the picture

Nothing above is a recommendation. It is a record. These are the filings that would change the description:

Until one of those prints, the filing record describes a stock the broad register holds in size — 1,428,144,334 shares across 2,859 filers — whose tracked superinvestors hold 62,063 shares in total, whose insiders have bought exactly once, and whose congressional record is tied three to three.

Six of 83: The Superinvestors Hold Little Tesla — and Cut a Third of It in Q2
Six of the 83 superinvestors we track hold Tesla — one name is 84.8% of the cohort — and the cohort cut its aggregate share count 33.2% in the second quarter while all institutions added 27.9%, insiders filed one report in 90 days with zero purchases in a year, and short interest sits at 1.74% of shares outstanding.
80% Overlap, No Copycat Signal: Congress vs. the Superinvestors
Four of five congressional stock buys land in a stock the superinvestors hold — 688 shared names. But ticker by ticker, how often Congress buys a stock has almost nothing to do with how many managers hold it (ρ = 0.099), and the shared names did not pay better.
