Positions as of Dec 31, 2025, from Altimeter Capital's 13F filing with the SEC. A 13F lists a manager's US-listed stocks and options at a quarter end and is filed up to 45 days later, so the fund may hold something else today. It leaves out short positions, cash and holdings outside the US.

Holdings
As of Dec 31, 2025. Changes are in shares against Sep 30, 2025, so a price move alone never reads as a buy or a sale.

Price is a stock's reported value over its shares at the quarter end. The estimated gain is the shares held at both quarter ends times the change in that price: shares bought or sold during the quarter add nothing, options are left out, and a stock split is read into the earlier share count and price.
