We haven’t heard anything official from the U.S. Postal Service and, even when we do, it won’t be the complete U.S. 2026 stamp program. Still, it’s fun to try to guess what stamps will be issued.
These are pretty definite:
Lunar New Year (Year of the Horse)
Bicentennial issues
6 issues at Boston 2026, including the Encore winner
I think these are good bets, all born in 1926:
Civil rights leader Ralph Abernathy (Black Heritage Series?)
Singer Tony Bennett (died 2023)
Musician Chuck Berry
Some 1876 events that might be commemorated:
Centennial International Exhibition (1876) in Philadelphia, first official world’s fair to be held 
in the US. (Opened May 10; stamp or stamps at Boston 2026?)
Colorado Statehood
The National League of Professional Base Ball Clubs is formed
First successful telephone call (stamp in 1976)
The Adventures of Tom Sawyer is published
A 1926 event that I think is a good bet for commemoration:
U.S. numbered highway system is established, including Route 66.
Less likely births in 1926:
Comedian/philanthropist Jerry Lewis
Author Harper Lee (“To Kill A Mockinbird”)
Comedian Don Rickles
Actor Andy Griffith
Mel Brooks – still living!
Less likely events from 1876:
Introduction of Heinz Tomato Ketchu
Introduction of Budweiser Beer
Less likely events from 1926:
First weather map is televised! (from one government office to another)
The 8-hour, 5-day work week is announced by Henry Ford
NBC Radio Network established (CBS isn’t founded until 1928)
Winnie the Pooh is published, but in London
Pretty definite:
LOVE (wish this series would die)
Priority Mail new rate
Express Mail new rate
USPS issued a 15 stamp pane showcasing the Appalachian Trail. I wonder if they’ll decide to issue a series of stamps showcasing some or all of the National Scenic Trails; there are 10 of them. Of the ten, three are overwhelmingly favored by long distant hikers like me – the Appalachian Trail (AT), the Pacific Crest Trail (PCT), and the Continental Divide Trail (CDT). Hikers who complete the “Big Three” are designated “Triple Crowners” by the hiking community.
Really long distance times would favor the American Discovery Trail (coast to coast) via 2 different routes.
