almost all 401k plans offer funds based on s&p 500, not nasdaq/russell others. s&p has also halved their trading days requirement from 1 yr to 6 months, but that's still sufficient to be past the post-ipo lock-up period.
I don't think the S&P has actually made a decision yet. It is in progress, though: "The S&P Index Consultation on MegaCap IPOs" is the search term
