Bitwise Launches Bitcoin-Focused ETF Tracking Corporate BTC Reserves
Bitwise Invest has introduced the Bitwise Bitcoin Standard Corporations ETF (OWNB), an exchange-traded fund designed to follow publicly traded companies that hold at least 1,000 bitcoin (BTC).
The ETF operates on a structured weighting system: eligible companies are ranked based on their bitcoin holdings, with the largest position capped at 20%. Firms with less than 33% of total assets in BTC receive a 1.5% weighting, and the index undergoes a quarterly rebalancing to maintain its strategy.
By the end of 2024, publicly traded companies had amassed 591,817 BTC, according to Bitwise. The ETF, set to trade on NYSE Arca, carries an expense ratio of 0.85%.
Currently, 70 public firms hold bitcoin on their balance sheets. The ETF’s top three positions include:
- Strategy – 20.87%
- MARA Holdings – 12.12%
- CleanSpark – 6.26%
