Key points

  • Pershing Square's Uber (UBER) position is worth about $2.15 billion — 15.7% of Bill Ackman's disclosed portfolio and its third-largest holding, behind Brookfield and Amazon.
  • Nancy Pelosi disclosed an Uber purchase of $500,001 to $1,000,000, transacted on May 29 and reported on June 24. She is the only member of Congress with an Uber trade in our congressional-disclosure record; Benzinga has reported the overlap between her book and Ackman's.
  • Uber's own executives and directors have bought nothing on the open market. Across 50 recent Form 4 filings reviewed by InsiderBuying.com there is not one open-market purchase — every line is compensation-related.

An activist manager and a congressional filer arrived at the same stock from opposite ends of the market. The people who run it did not join them with their own money.

What the disclosures say

Ackman runs eleven positions. At 15.7% of the book, Uber is not a trial — it sits alongside Brookfield at 17.6% and Amazon at 17.4% as one of three names carrying the fund.

The Pelosi trade is disclosed as a range, which is how the STOCK Act works: members report a band, not an exact figure. The band here is $500,001 to $1,000,000, and the gap between the May 29 transaction and the June 24 report is 26 days — inside the 45-day window the law allows.

Why the Form 4 record matters here

A 13F is a quarterly photograph of an outside manager, filed up to 45 days late. A congressional PTR is a range, filed up to 45 days late. A Form 4 is an insider spending their own money, filed within two business days — the only one of the three that is both precise and prompt.

On Uber that record is empty of purchases. Fifty filings, no open-market buys. As at Alphabet, that is unremarkable for a company of this size, where executives are paid in stock and sell it. But it means the conviction on display belongs to outside money, and the distinction is worth keeping straight.

The bottom line

Ackman has $2.15 billion in Uber. Pelosi disclosed a purchase of up to $1 million. Uber's insiders have bought none on the open market. Two of those three facts come from filings that are quarterly or banded; only the third is measured in dollars and days.
