By Barclays increased its reported holdings of BlackRock’s spot Bitcoin exchange-traded fund by 48% during the third quarter, adding to early evidence that major banks continued building exposure to regulated Bitcoin investment products.
The British bank reported 3.94 million shares of the iShares Bitcoin Trust ETF, or IBIT, worth approximately $186.7 million as of Sept. 30, according to its latest Form 13F filed with the U.S. Securities and Exchange Commission. That compares with 2.66 million shares valued at about $88.5 million at the end of June.
The increase of roughly 1.28 million shares is more meaningful than the jump in reported dollar value because IBIT itself appreciated substantially during the quarter. Barclays therefore added to its position rather than simply benefiting from higher Bitcoin prices.
How Much Did Barclays Actually Increase Its IBIT Holdings?
Barclays’ filing breaks its direct IBIT ownership across several reporting managers. Combined, those positions totaled 3,942,900 shares at the end of September, up from 2,658,147 shares three months earlier.
The bank also disclosed large put and call positions tied to IBIT. That makes it difficult to interpret the reported shares as a straightforward proprietary bet on Bitcoin. Form 13F filings disclose certain long U.S. securities and options positions but do not reveal short positions, option strike prices, expirations or other hedges that may offset the exposure.
The same issue applies when analyzing other banks and market makers. UBS sharply increased IBIT call exposure during the second quarter while also holding the ETF directly, illustrating how banks can use Bitcoin funds for client activity, hedging and trading as well as investment.
Investor Takeaway
Barclays’ 48% increase in IBIT shares is stronger evidence of rising activity than the doubling of the position’s dollar value. It still does not establish that the bank itself made an unhedged directional Bitcoin investment.
Is Citigroup Showing the Same Pattern?
Citigroup also increased its reported spot Bitcoin ETF exposure during the third quarter, suggesting Barclays was not an isolated case.
Citi disclosed 521,144 IBIT shares worth about $24.7 million at Sept. 30, up approximately 50% from 347,114 shares at the end of June. More notably, the bank reported a new position of 1.64 million shares in Fidelity’s Wise Origin Bitcoin Fund, valued at approximately $118.9 million.
That gave Citi roughly $143.5 million of disclosed direct holdings across the two Bitcoin ETFs, excluding its IBIT options positions.
Institutional ownership has already broadened well beyond banks. University endowments, sovereign funds, hedge funds and trading firms have all appeared in recent 13F disclosures. Harvard retained a $101 million IBIT position during the second quarter, while Abu Dhabi’s Mubadala and Abu Dhabi Investment Council together continued to hold hundreds of millions of dollars of the BlackRock fund.
Investor Takeaway
The bank filings matter less as evidence of a single bullish trade and more as evidence that Bitcoin ETFs are becoming standard instruments inside large financial institutions. Banks can now hold, hedge, trade and offer exposure through infrastructure already used for conventional ETFs.
Why Share Counts Matter More Than Dollar Values
Comparing reported values between quarters can exaggerate changes in investor exposure when the underlying ETF has moved sharply. IBIT rose substantially during the third quarter, meaning part of the increase in the dollar value of institutional positions came from market appreciation rather than purchases.
Barclays is a useful example. Its IBIT position rose from about $88.5 million to $186.7 million, an increase of more than 100%, while the actual number of shares increased by about 48%. Citi’s IBIT share count rose by roughly 50%.
The distinction has become more important as institutional Bitcoin exposure grows. FinanceFeeds previously noted that Jane Street’s roughly $1 billion of reported Bitcoin ETF holdings did not necessarily represent a $1 billion directional Bitcoin position because 13F disclosures show only part of a trading firm’s overall book.
CoinShares’ October fund-manager survey offers a separate indication of how institutional attitudes are changing. Diversification accounted for 40% of respondents’ reasons for holding digital assets, while speculation represented less than 9%. Bitcoin and Ethereum remained core holdings across the surveyed portfolios.
Will Q3 Institutional Buying Hold Through the Latest Outflows?
The September filings are backward-looking. They show positions as of Sept. 30 and therefore predate Bitcoin’s subsequent decline and the renewed withdrawals from U.S. spot Bitcoin ETFs during the fourth quarter.
Recent sessions have included substantial redemptions from IBIT. BlackRock’s Bitcoin fund recorded $213.2 million of withdrawals on Nov. 9 alone, extending a run of outflows as Bitcoin traded well below its earlier 2026 highs.
The remaining Q3 filings will therefore answer one question about institutional ownership, while fourth-quarter filings will answer another: whether banks and other large investors maintained or expanded those positions after the market reversed.
Investor Takeaway
Barclays and Citi show that regulated Bitcoin exposure continued moving deeper into traditional finance during Q3. The stronger test will come in Q4 filings, which will reveal whether those positions survived the subsequent Bitcoin selloff and ETF redemption cycle.
