📝 Executive Summary
Barclays and Citigroup increased their exposure to spot Bitcoin ETFs in the third quarter, according to recent 13F filings. Barclays grew its iShares Bitcoin Trust (IBIT) stake by 48% to 3.94 million shares, while Citigroup disclosed a new $119 million position in Fidelity’s FBTC. Despite the rise in institutional holdings, analysts warn that valuation gains reflect Q3 price increases and that the data predates $2.1 billion in Q4 net outflows.
