Harbor’s proposed Lab ETFs aim to broaden access to private AI-linked investment themes, though concentrated exposures and management fees could limit diversification benefits for investors.
Harbor Funds has filed for five actively managed Lab ETFs linked to the ecosystems surrounding Anthropic, DeepMind, Meta, OpenAI and xAI. The new update indicates the products are positioned as a way to broaden investor access to private AI company themes, while also noting potential drawbacks including concentrated risk and management fees that may challenge diversification strategies. The filing remains focused on thematic exchange-traded funds in which portfolio managers select holdings rather than track a fixed index.
