State Street CorpState Street's SPDR Portfolio S&P 500 ETF is highlighted as one of the top-gaining ETFs with $43.5B in net flows, reflecting strong investor demand for its products.

Global exchange-traded fund assets reached a record $23 trillion at the end of May, driven by inflows surpassing $1 trillion for the year so far, according to data from ETFGI. The milestone, achieved less than halfway through 2026, follows a record-breaking 2025 for launches, inflows, and assets under management. Deborah Fuhr, managing partner and cofounder of ETFGI, noted that a small number of large funds dominate, with about 1,600 ETFs holding over $2 billion each accounting for roughly 85% of total assets. The Vanguard S&P 500 ETF led with $58.8 billion in net flows year-to-date, followed by the iShares Core S&P 500 ETF at $55.7 billion and the State Street SPDR Portfolio S&P 500 ETF at $43.5 billion. Bloomberg Intelligence analyst James Seyffart said ETF usage has expanded beyond long-only passive investing, with strong demand for products tied to artificial intelligence, semiconductors, and other themes.
