Reddit (RDDT) confirms inclusion in the S&P 500, effective before market open on August 18, replacing the acquired AVB. It briefly surged about 11% after hours.

Passive buying from index funds is real, tangible demand. But getting added to the index isn’t a free lunch—historically, many stocks have “announced a rise and been included in a decline.”

This is similar to the logic behind ETF approvals in the crypto asset space: forced buying supports underlying structural demand, but “buy the expectation, sell the fact” holds true on both sides. Traditional finance is accelerating its absorption of community-based assets—this is a signal worth watching for the crypto market.
