Altimeter Capital portfolio value: what the 13F reports, and why it is not AUM
Altimeter Capital reported $9.83 bn of positions on its Form 13F-HR for the quarter ending 2026-06-30, filed with the SEC on 2026-08-14 — 45 days after the quarter closed. By reported 13F value that makes it the 33rd largest of the 59 funds tracked here, between Durable Capital ($10.28 bn) and Greenhaven Associates ($8.66 bn).
That $9.83 bn is the 13F portfolio value, not Altimeter Capital's assets under management (AUM). A Form 13F lists the long positions a manager held in US-listed securities on the last day of the quarter. Cash, bonds, positions listed outside the United States, private investments and anything held short are not on the form, and options are left out of the figures on this page. Altimeter Capital's total AUM can therefore be larger than $9.83 bn, and for a manager that also runs short positions the 13F shows only one side of the book. What the number does give you is exact: it is Altimeter Capital's own count of its long US equity holdings on 2026-06-30, as filed.
Altimeter Capital top holdings in Q2 2026: how concentrated the portfolio is
The largest position Altimeter Capital reported is Nvidia Corporation (NVDA), at 19.16% of the portfolio — $1.88 bn. The top three — NVDA, CBRS and META — add up to 43.2%, and the top five to 56.2%. All 10 positions listed here come to 83.3% of what the fund reported, or $8.19 bn. With 83.3% of the reported book in 10 names, this is a concentrated portfolio: the table above is close to the whole filing, and a single position moving changes the picture.
Compared with the filing for the quarter before: CBRS is a new position; TSM, CRWV, AMZN and MSFT were added to; META, ARM and UBER were cut back; NVDA and SNOW were left unchanged. A position sold in full during the quarter drops off the form altogether, so exits cannot be read from this list.
Funds whose top holdings overlap most with Altimeter Capital
Of the 10 positions above, Appaloosa reports 5 of the same names (NVDA, META, TSM, AMZN, UBER); Tiger Global reports 5 of the same names (NVDA, META, TSM, AMZN, MSFT); Fisher Asset Management reports 4 of the same names (NVDA, TSM, AMZN, MSFT); Pershing Square reports 4 of the same names (META, AMZN, UBER, MSFT); Tudor Investment reports 4 of the same names (NVDA, TSM, AMZN, MSFT). Overlap is counted against each fund's own largest reported positions, so a fund holding the same stock as a small position does not show up here.
Altimeter Capital 13F: questions and answers
What is Altimeter Capital's largest holding?
Nvidia Corporation (NVDA), at 19.16% of the reported portfolio ($1.88 bn) as of 2026-06-30. Cerebras Systems Inc (CBRS) is second at 16.24%, followed by Meta Platforms Inc (META) at 7.76%.
What is Altimeter Capital's AUM?
Its latest Form 13F reports $9.83 bn of long positions in US-listed securities for 2026-06-30. That is the 13F portfolio value rather than total AUM: cash, bonds, non-US listings, private holdings and short positions are not included, so the firm-wide figure Altimeter Capital manages can differ from it.
What did Altimeter Capital buy and sell in Q2 2026?
Among its 10 largest positions, the Q2 2026 filing shows new positions in CBRS; additions to TSM, CRWV, AMZN and MSFT; reductions in META, ARM and UBER. The form compares share counts between two quarter ends, so it does not show the dates or prices of the trades, and positions sold out completely are absent rather than marked.
When does Altimeter Capital file its next 13F?
The filing shown here covers the quarter ending 2026-06-30 and was filed on 2026-08-14, 45 days after quarter end. Form 13F is due within 45 days of each quarter end, so the next one — for the quarter ending 2026-09-30 — is due by 2026-11-14.
How many stocks does Altimeter Capital hold?
This page lists its 10 largest reported positions, which cover 83.3% of the reported value. The full filing can contain more: positions below 0.5% of the portfolio, and anything past the top 10, are not listed here, so 10 is not the number of stocks Altimeter Capital owns.
Source: SEC EDGAR, Form 13F-HR — public domain, reproduced as filed. The table above is not the fund's entire portfolio. The list is capped at 10, so the 10 shown add up to 83.3% of what the fund reported — the rest does not appear here. 13F carries up to a 45-day reporting delay, covers long positions in US-listed securities only, and excludes options and short positions. Values are as reported in the filing, not current market value. No price data is involved in the figures above. Names are EDGAR's own spelling.
