State Street XLK Tops $100B as AI Drives Tech Flows

The State Street Technology Select Sector SPDR ETF, known by its ticker XLK, exceeded $100 billion in assets, reaching about $116 billion on May 14, 2026. The fund is managed by State Street Global Advisors.

XLK provides exposure to the technology sector of the S&P 500. Its holdings include companies in semiconductors, software, IT services, communications and other technology-related industries. The fund weights holdings by market capitalization, so the largest U.S. technology companies make up the biggest allocations.

Investors have directed inflows into XLK to gain access to large-cap technology names tied to artificial intelligence, rising cloud-computing demand and semiconductor production. Flows into technology-focused exchange-traded funds have been strong this year.

Performance has supported investor interest: XLK’s net asset value rose 29.51% over the 12 months ending March 31, 2026. The ETF is commonly used by investors who want concentrated exposure to large-cap tech without selecting individual stocks.

XLK’s scale places it among the largest single-sector ETFs. Its size offers liquidity and a way to increase a portfolio’s allocation to U.S. large-cap technology.

Market participants cite corporate investment in AI capabilities, persistent demand for advanced semiconductors and upgrades to enterprise software and infrastructure as factors that have drawn capital to technology sectors and ETFs such as XLK.
