You can make a Tahoe bootable USB installer by first formatting a 32GB or 64GB usb as Mac OS Extended (Journaled) and naming it Untitled.

After downloading the Tahoe Beta 1 installer (which so far is nameless, even though we now know it has the name Tahoe) you can run this in Terminal to make the bootable USB:

sudo /Applications/Install\ macOS\ Beta.app/Contents/Resources/createinstallmedia --volume /Volumes/Untitled

(Note: Adora has link to full installer in this post )

The command for future betas will probably change to

sudo /Applications/Install\ macOS\ Tahoe\ beta.app/Contents/Resources/createinstallmedia --volume /Volumes/Untitled

and then with public release (or even release candidates) to

sudo /Applications/Install\ macOS\ Tahoe.app/Contents/Resources/createinstallmedia --volume /Volumes/Untitled

the full installer for beta 1 looks like this:

They will probably make a prettier one for beta 2 and thereafter

interesting that beta 1 is called Install macOS Beta and not Install macOS 26 Beta

the 26 was supposed to be a secret as was the name Tahoe, so we don't see either of those in the installer name

of course we did know because they got leaked, but that is beside the point

last year the first sequoia beta 1 installer was called Install macOS 15 Beta, so they had the 15 there but not the name Sequoia.
 
nope. it works for apple silicon as well.

the only difference is how to access the startup manager to select the usb

for intel hold down option key when starting up, for apple silicon, hold down power button
