The logic isn’t the same. We’ve had plenty of history to judge Alphabet’s financials. It’s less about AI and more about allowing the market to appropriately price the stock after seeing their filings for a period of time.
However the market hasn't priced these new stocks at all, the existence of index trackers is being exploited to force prices on enough buyers to make the prices stick. This is the wrong way around. It's market manipulation. It's using the behaviour of index funds to influence prices, decoupling those prices to at least some extent from the discretion of market participants.
Let the market price the stock, then the index trackers can buy in, this is exactly why these rules exist, and why it's a travesty that the NASDAQ is waiving them.
