RESEARCH — THE FILING TAPE #25

Twelve of 83: Pershing Square's New Position Is 54.8% of the Superinvestors' Uber Stake. Its CEO Bought Shares in September.

October 9, 2026

GetCoattail Research — Uber is the market's autonomy argument: record bookings, a stock 32.0% below its October 2025 closing high in our price file, and analyst targets split between $73 and $110. We ran it through every filing lens we maintain. Twelve of our 83 superinvestors hold it long — 62,694,081 shares — and more than half of that cohort is one position opened in the second quarter. Its insiders, unusually for this series, bought more than they sold in the last 90 days.

Start with the narrative: scale the market is pricing as an autonomy question. Uber's second quarter of 2026 was reported with gross bookings of $58.0 billion, up 22% year over year in constant currency, revenue of $14.19 billion, up 12%, and adjusted earnings per share of $0.81, up 35%. Trips reached 3.87 billion, up 18%, monthly active platform consumers 208 million, up 16%, and trailing twelve-month free cash flow crossed $10 billion for the first time. Management guided third-quarter gross bookings to $58.25–$60.25 billion. The argument around the stock is not the bookings line: it is whether robotaxis run by others eventually take the economics of the trip. Uber has answered with partnerships — Pony.ai robotaxi testing planned in London, autonomous operations targeted in 15 cities by end-2026 — and a roughly $2.3 billion cash agreement to acquire ezCater. Analyst targets frame the split: Citizens JMP reaffirmed Market Outperform and a $100 target on October 9, Wolfe Research has set $110, and Melius downgraded the stock to Sell at $73. Next earnings: November 3, 2026. AltIndex's Reddit-mention ranking places Uber seventeenth, at 107 mentions — the highest-ranked stock we had not yet audited once the sixteen names above it, all previously covered or skipped in this series, were set aside.

Now the filings. GetCoattail tracks the investors best placed to know any company: superinvestors, institutions, insiders, Congress, and 5% holders. For Uber — the twenty-fifth Filing Tape audit — the story is a cohort transformed by two new positions, insiders whose recent buys outweigh their sales, a congressional register in one chamber only, and a shrinking borrow.

Lens 1: the superinvestors — twelve holders, and two new positions are 69.0% of the cohort

We track 83 large, mostly long-only managers whose 13F portfolios we collect directly from SEC EDGAR. As of June 30, 2026, 12 held Uber in a long common-stock position — long rows, no option rows. Together they held 62,694,081 shares worth $4,524,004,875. The direction count: two new, three increased, five decreased, two unchanged — and the two new positions together hold 43,269,351 shares, 69.0% of the entire cohort.

The largest of them rewrites the register. Bill Ackman's Pershing Square reported 34,326,200 shares worth $2,476,978,592 as a new position, a 12.72% portfolio weight — 54.8% of the entire cohort alone. The second new position is Terry Smith's Fundsmith, with 8,943,151 shares worth $645,337,776, a 4.73% weight. Behind them, David Tepper's Appaloosa holds 7,694,071 shares worth $555,204,163, a 7.19% weight, increased 21.5%. The remaining nine are smaller and mostly trimmed: Russo 5,084,015 shares (−1.7%); Armitage 2,319,648 (−50.1%); Dorsey 1,761,941 (+61.6%); First Pacific 976,544 (+0.7%); Polen 570,063 (−80.5%); IMA 485,805 (−1.6%); Cantillon 238,965 (−95.4%); Tiger Global 151,178 (unchanged); Markel 142,500 (unchanged). The top three together are 81.3% of the cohort. On the pipeline's CUSIP basis in both quarters, the cohort total ran from 26,628,915 shares at March 31 to 62,208,276 at June 30 — up 133.61% — in a quarter when the price moved from $71.93 to $72.16, up 0.3% (see methodology for a one-manager difference between the pipeline and EDGAR-collection totals).

Uber through six filing lenses
Chart 1: Signal presence by cohort. Superinvestors: 83 managers, 2026Q2 13F (as of Jun 30, 2026). Institutions: full-market 13F aggregation, same date. Insiders: Form 4 record through Oct 2, 2026. Congress: Senate and House PTR record through Oct 3, 2026. 13D/G: filings through Apr 30, 2026. Short interest: FINRA biweekly settlement data through Sep 15, 2026. Source: SEC EDGAR; FINRA; GetCoattail collections.

Lens 2: institutions — a broad register that grew shares faster than filers

Zoom out to the whole 13F market: the register is broad and growing. At June 30, 2026, 2,419 institutions reported positions, up from 2,397 at March 31 (+0.92%), and 2,403 reported long positions. Reported shares rose 13.62%, from 1,466,397,587 to 1,666,051,930 shares, with 1,732 filers entering and 1,710 exiting. Reported aggregate value rose 15.00% to $126,220,308,766; the aggregate includes option rows, so we headline filer and share counts and label dollars "reported" (see methodology). The implied value per share, $75.76, sits 5.0% above the June 30 close of $72.16 — a modest gap by this series' standards, and a sign that most of this name's reported value runs through common shares, not option rows.

Lens 3: the 5% register — four filings, all 13G, no activist

Four SC 13D/G filings cover Uber — zero in the 13D family and four 13G filings, two of them amendments, three reporting names, most recently filed April 30, 2026, maximum reported percentage 9.15%. The largest row belongs to The Vanguard Group, which reported 190,827,921 shares (9.15%) as of September 30, 2025, filed October 31, 2025. Vanguard Capital Management reported 154,014,044 shares (7.53%) as of March 31, 2026, filed April 30, 2026. Capital Research Global Investors reported 118,131,681 shares (5.6%) as of December 31, 2024. The Vanguard Group also reported a 0-share row as of March 13, 2026 — the same sequence seen in several earlier audits, where a Vanguard position reappears under a related reporting name; we report rows as filed, without summing them or calling the zero an exit.

Lens 4: insiders — six purchases in the record, and the last 90 days bought more than they sold

This register is the series' exception twice over: the buy column is not empty, and recently it is the larger column. Across the parsed Form 4 record (211 filings through October 2, 2026), there are six open-market purchases totalling 233,458 shares and $16,914,260.84, by four buyers — all six recorded as officer purchases. Against that stand 27 sales totalling 818,991 shares and $75,465,225.55, by five sellers, all 27 recorded as officer sales. All six purchases fall in the most recent year (116 filings), which also holds seven sales totalling $5,852,012.22. In the 90 days through October 2, 2026, 22 filings covered three purchases totalling 211,000 shares and $15,314,015.88, by two buyers, against one sale of 28,170 shares and $2,008,673.12 — a net purchase of 182,830 shares. Our site's insider aggregate (October 10, 2026) records exactly the same 90-day figures and flags a chief executive purchase in the window, most recently dated September 10, 2026; market reporting put Chief Executive Dara Khosrowshahi's purchase at 141,000 shares at a weighted average of $70.96, roughly $10.0 million. Some selling is mechanical — vesting, tax withholding and pre-arranged plans — and we assign no motives.

Lens 5: Congress — three House members, no Senate record

Across the congressional record we maintain (combined record as of October 3, 2026), Uber's register holds three members, three purchase transactions and two sale transactions, most recent purchase July 10, 2026, both parties represented — all of it in the House file (as of October 3, 2026). The Senate aggregate (as of October 1, 2026) carries no Uber record. Congressional disclosures report value ranges, so this lens records direction and counts only.

Lens 6: short interest — down 49.7% from its 2022 peak, at 2.24% of the share count

As of September 15, 2026 — the most recent FINRA settlement date — 45,718,444 Uber shares were sold short, with days-to-cover of 2.33, up 1.32% from the prior settlement. The series peak stands at 90,806,927 shares on May 13, 2022, so the latest reading is 49.7% below the peak; the June 30, 2026 settlement recorded 56,087,568 shares, so the borrow has fallen 18.5% since quarter-end. Against the 2,042,560,121 shares in our fundamentals file (as of July 31, 2026), the borrow is 2.24% of the share count. Year over year: the September 15, 2025 settlement recorded 52,783,148 shares, so the borrow is down 13.4%.

Short interest in Uber
Chart 2: Shares sold short in Uber at each FINRA biweekly settlement, Jan 2024 – Sep 15, 2026 (n = 65 settlements in the chart window; the full collected series runs 137 settlements from Jan 15, 2021). The peak reading, 90,806,927 shares on May 13, 2022, is the maximum of the full collected series and predates the chart window; the latest reading, 45,718,444 shares on Sep 15, 2026, is 49.7% below that peak and 13.4% below the 52,783,148 shares recorded on Sep 15, 2025. Source: FINRA Equity Short Interest files; GetCoattail collection (uber_short_interest_series.csv).

The recent settlements run 51,841,219 on July 15, then 47,409,310, 46,397,214, 45,121,710 and 45,718,444. The series began at 53,076,559 shares on January 15, 2021; its lowest reading is 29,996,328 on January 13, 2023 — the May 2022 peak was roughly three times that low.

The gap, stated plainly

The registers describe a stock the tracked smart money joined late, in size, and mostly through two doors. Twelve of 83 tracked superinvestors hold Uber — 62,694,081 shares — but 69.0% of that cohort arrived as new positions in one quarter, and Pershing Square alone is 54.8% of it. The full market was already there: filers rose 0.92% to 2,419 while reported shares rose 13.62% to 1,666,051,930. Insiders are the second exception: six purchases totalling $16,914,260.84, all by officers, all within the last year — against 27 sales totalling $75,465,225.55 across the full record, but only $2,008,673.12 of sales in the last 90 days against $15,314,015.88 of purchases. Congress registers a small House-only record: three members, three purchases, two sales, nothing in the Senate file. And the borrow, at 45,718,444 shares and 2.24% of the share count, is down 13.4% in a year and 49.7% below its May 2022 peak. One plausible reading is that the filings crowd reached this name after the price had fallen — new tracked money and insider buying arriving into a drawdown, while the borrow that once pressed the stock has retreated for years. 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 record describes a stock held by twelve of our 83 tracked superinvestors — 62,694,081 shares, 54.8% of them one new Pershing Square position — whose insiders bought six times and bought more than they sold in the last 90 days, which three House members have traded and no senator has, and whose borrow, at 45,718,444 shares, has fallen 13.4% in a year to 2.24% of the share count.

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.

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.
