800VDC AI Datacenter Ecosystem ETF is an actively managed exchange-traded fund sponsored by Harbor ETF Trust and advised by Harbor Capital Advisors, Inc., focused on providing investment exposure to companies positioned to benefit from the transition of AI datacenters from legacy low-voltage power architecture to next-generation 800-volt direct current (800VDC) power delivery systems, with an emphasis on power semiconductors, power management, sensing and protection, electrical infrastructure, and related technology providers. The fund seeks to invest at least 80% of its net assets, plus borrowings for investment purposes, in securities of 800VDC datacenter ecosystem companies, and its portfolio is expected to include a concentrated group of U.S. and international issuers across information technology and industrials segments.

Recent company developments include the SEC registration and post-effective amendment process in June and September 2026, followed by the ETF’s launch and market listing, marking its entry into the public market as a new thematic AI infrastructure strategy.
