What much XP on Insiders Hub would I need to become eligible for console stream?

I don't think there is a requirement, but you may want to ask at the Insider Reddit. https://www.reddit.com/r/xboxinsiders/

Hi there Jaman32,

Thanks for reaching out here in Xbox Forums. I understand you have a question on the insider program. I recommend checking out the following article:

• Xbox Insider Program FAQ
  • As an Xbox Insider, you’ll decide your level of involvement. You’ll automatically become eligible to join more and more Insider content previews based on your interests, tenure as an Xbox Insider, Xbox Insider XP score, and activities you participate in.

For more info on getting and using the Xbox Insider Hub see
Get the Xbox Insider Hub app.

Hope this helps.

Any activities that are available would be listed in the Insider Hub. You would want to check there for any quizzes or other activity that can boost your XP in the program.

Hi ClaimingDuke263,

Have you been accepted onto the Xbox Console Streaming (Preview) program? This should be found in the Insider Content section of the Xbox Insider
Hub app. I have quoted the below from the Xbox Console Streaming (Preview) program FAQ found at the bottom of the page.

“To participate in the Console Streaming (Preview), download the “Insider Hub” app to your Xbox One console. Then, download the “Xbox Game Streaming (Preview)” app on your Android device. Follow the steps in the app on your mobile device to pair your
console and phone. Then, start playing the games you already own! Please note, the initial roll out to Insiders will be phased. For the most up to date details on which Insider rings have access to the Preview, please visit insider.xbox.com.”

I would recommend checking if you signed into the same account on the streaming app as you have the insider hub or if your in project cloudx it should let you,when i tryed the app and logged in with insider hub it wouldn't let me stream my xbox apps because
it was not in my ring region yet so that could be the problem.
