The Anthropic ETF holds no Anthropic, and still out-raised Harbor's other four AI funds
Harbor's Anthropic AI Lab Ecosystem ETF gathered $13.5 million in its first month selling chipmakers, cloud giants and bitcoin miners rather than the company itself, whose listing has reportedly slipped toward November.

The stock everyone wants does not trade
Anthropic confidentially filed for an IPO on 1 June 1. The Wall Street Journal and the New York Times reported on 18 September that the listing has slid from October into November, toward a valuation near $2 trillion 2. Investors who will not wait now have something to buy: Harbor Capital Advisors launched the Anthropic AI Lab Ecosystem ETF in mid-August 3.
The demand is real, and Harbor is selling it
Anthropic's annualized revenue run rate passed $65 billion at the end of July, up from $47 billion in May and about $9 billion at the end of 2025 4. Private investors marked the company at $965 billion in May, more than double its $380 billion February valuation 4. Harbor's fund turned one month of that hunger into $13.5 million, up about 5% since launch, more than the $10.4 million combined across its four siblings tracking Meta, Google DeepMind, SpaceX and OpenAI 3.
Anthropic's revenue run rate has multiplied sevenfold in seven months

The label is the only Anthropic in the fund
The fund holds no Anthropic equity 5. What it holds is Broadcom, AMD, Micron, Amazon, Alphabet and Microsoft, plus the bitcoin miners TeraWulf, Hut 8 and Riot Platforms, which Barron's notes have all announced data-center deals tied to Anthropic 3. Nvidia, Oracle and Quanta Computer recur across several of the five wrappers, so buying the theme repeatedly buys much the same portfolio 3.
The miners are the only new economics
Anthropic signed a 20-year lease on TeraWulf's Kentucky site worth an estimated $19 billion in revenue, by TeraWulf's own count 6. Its $35 billion compute deal with the Nvidia-backed cloud firm Lambda runs through Hut 8's Texas campus, where two long-term leases are worth $19.6 billion, 260 times the miner's latest quarterly revenue 7. The supplier economics are real. The risk is too: Harbor's Munificent Seven energy sibling is down about 2% since its late-August launch 3.
The manager's defense, and its limit
"This is a durable and sustainable theme," portfolio manager Justin Menne told Barron's, with adoption "still very much on an upward projection"; spreading money across ecosystems, he argues, beats one bet 3. Even the column that interviewed him closes with the warning that index funds are already overloaded with tech and thematic funds concentrate it further 3.
What November decides
Kalshi's contract on an IPO confirmation before 1 December sits at a 50 percent implied probability, with further delay priced in 1. Filings for single-stock leveraged Anthropic ETFs are already queued for listing day 3. When the real thing trades, the question is whether $13.5 million stays in the imitation.
