Why Reddit is joining the S&P 500 now
S&P Dow Jones indexes said after the close on Thursday that Reddit will replace AvalonBay Communities in the S&P 500 before the market opens on Aug. 18. AvalonBay was just acquired by Equity Residential, freeing a slot in the index outside the usual rebalancing schedule.
Funds that track the S&P 500 have to own every company in it, at whatever weight the index assigns. The buying is automatic and mechanical. JPMorgan estimates that, in total, about 16.7 million Reddit shares will be bought up.

Reddit's growth is impressive, but there's a catch
Reddit generated $805 million in second-quarter revenue, up 61% year over year (YoY), while net income reached $253 million. Daily active users -- a key metric for social media platforms -- increased 18%.
That all sounds very positive, but it obscures a major issue the platform is facing. AI search results are more and more keeping users from clicking through to Reddit itself. If this trend continues, it could spell real trouble for a company that needs to keep growing at a rapid pace to support its valuation.
