Based on current rules they wouldn't included in the S&P 500 for at least several years even based on optimistic scenarios.

Of course IIRC they looking into tweaking the rules to allow some handpicked extremely unprofitable companies in, due to "reasons"....

They are scared of underperfoming the market and failing to exist as an index. Losing money with everyone else is a more sustainable risk than losing money while other indexes go up.
