S&P 500 Rebalance Hours Away as Marvell Eyes Addition at 7,584

Markets await the S&P 500 quarterly rebalance announcement after Friday’s close, with Marvell Technology ($245 bn market cap) the leading candidate for addition alongside Flex and Reddit. Earlier anticipation of rule changes to accelerate mega-cap IPOs such as SpaceX, OpenAI and Anthropic was dashed on 4 June when S&P Dow Jones Indices rejected any shortening of the 12-month seasoning period or waiver of GAAP profitability requirements. The status-quo decision leaves the benchmark at 7,584.41, shifting attention to conventional inclusions that will take effect before the open on 22 June.
