WeWork will not be in either the S&P 500 or the Russell 2000/3000 because last year they adjusted their qualifying criteria to exclude companies with multi-class share structures.[0] They didn't kick out any existing companies (why google, facebook et al are still in these indices) but no new companies will be added with multi-class share structures.
