Should be "are" since "Y" is plural subject.

I think X is the subject " X is one" so singular should be used here.

"One" is one of those special indefinite pronouns for which you must examine the object of the the preposition (the "of construction") to determine the whether to use a singular or plural verb.
Here "Y" is plural and hence that "are" is the right construction.

Focus on the MEANING.

John is THE ONLY ONE of the members WHO IS PLANNING TO ATTEND.

Here, John is THE ONLY ONE planning to attend.
No other members are planning to attend.
In other words:
Of the members, John is THE ONLY ONE WHO IS PLANNING TO ATTEND.
Since John is THE ONLY ONE, IS PLANNING is correct.

John is only one of THE MEMBERS WHO ARE PLANNING TO ATTEND.

Here, other members ARE PLANNING to attend.
John is ONLY ONE of these members.
In other words:
Of the MEMBERS WHO ARE PLANNING TO ATTEND, John is only one.
Since John is not THE only one -- other members ARE PLANNING to attend -- a plural verb is needed here.
