Nah, only thing is a group some dude created on reddit and called "YC P26 Waitlist". Although some people have their speculations, you won't find any concrete information.
If you want me to invite you there, let me know.
my reddit: u/baderbc
Created just a discord server for this, easier than manually people asking me for invite:
