Summary
Bitwise Investments launched the Bitwise Bitcoin Standard Corporations ETF (ticker: OWNB) on NYSE Arca, establishing the first exchange-traded fund specifically designed to track publicly traded companies that maintain at least 1,000 bitcoin on their balance sheets. The fund addresses institutional investor demand for equity exposure to the corporate "bitcoin standard" movement without direct or derivative-based cryptocurrency holdings.

The OWNB index construction captures a significant macro trend: more than 160 public companies collectively hold over 1 million bitcoin. The fund's portfolio concentrates on companies that have adopted bitcoin as a treasury reserve asset or core business operation. MicroStrategy dominates the holdings at 18.62% of fund weight, holding 650,000 BTC valued at approximately $47.8 billion. Marathon Digital Holdings represents the second-largest position at 10.02% weight with 53,250 BTC. Other substantial positions include Hut 8 (7.20%, 10,278 BTC), Riot Platforms (6.16%, 19,324 BTC), and Core Scientific affiliate XXI (5.89%, 43,514 BTC).

The fund's structure reflects institutional sophistication: OWNB commits to investing at least 80% of net assets in securities comprising the underlying index under normal market conditions, with no leverage to bitcoin through derivatives or indirect exposure mechanisms. This approach allows institutions to gain concentrated exposure to corporate bitcoin accumulation and mining operations while maintaining traditional equity fund mechanics, regulatory oversight, and custodial standards applicable to domestic equity ETFs.

The underlying holdings span multiple business models within the bitcoin economy. Holdings include bitcoin miners (Riot Platforms, CleanSpark, Bitdeer Technologies), infrastructure providers (Hut 8, Keel Infrastructure), corporate treasury players (MicroStrategy, Metaplanet), and diversified bitcoin-holding firms (Marathon Digital). This diversification within the bitcoin-standard corporate universe reduces single-company concentration risk while maintaining focused exposure to the thesis that major public companies view bitcoin as a strategic balance sheet asset.
