Bank of America has significantly increased its exposure to spot Bitcoin ETFs, with Bitcoin now dominating its disclosed crypto-related positions. The bank boosted its stake in BlackRock’s iShares Bitcoin Trust, known as IBIT, to approximately $37 million within a roughly $53 million crypto ETF basket. At the same time, it reduced holdings in Ethereum and Solana ETFs, reinforcing a clear preference for Bitcoin as the primary digital asset exposure. For crypto users, the key signals to watch include future 13F filings, aggregate Bitcoin ETF flows, and whether other major banks follow this Bitcoin-over-altcoins tilt.
In its Q1 2026 13F filing, Bank of America reported nearly $53 million in crypto ETF exposure, led by BlackRock’s iShares Bitcoin Trust, which accounts for around 70 percent of that total. One detailed breakdown shows the bank increased its IBIT position to 972,590 shares worth about $37.3 million, up from 719,008 shares in the prior quarter. Beyond IBIT, Bank of America holds smaller stakes in other spot Bitcoin products, including Bitwise’s BITB, a Grayscale Bitcoin Mini Trust, Fidelity’s FBTC, and modest allocations to GBTC, VanEck’s HODL, and ARK 21Shares funds. This approach diversifies issuer risk while keeping the core exposure firmly in Bitcoin ETFs. Separately, the bank also holds about 3.96 million shares of MicroStrategy, valued around $660 million, using it as an equity proxy for Bitcoin exposure alongside the ETF positions according to portfolio summaries.
While Bitcoin ETF holdings increased, Bank of America cut its spot Ethereum ETF exposure to roughly $1.06 million and trimmed Solana ETF positions, leaving only relatively small ETH, SOL, and XRP-linked ETF stakes. This shifts its disclosed crypto mix further toward Bitcoin. At the market level, total Bitcoin ETF assets are around $106.23 billion, up about 1.96 percent over the past month, indicating that, despite choppy weekly flows, ETF-based BTC exposure remains structurally significant. Bank of America’s move aligns with a broader pattern where institutions treat Bitcoin as the core asset and size ETH or other altcoins more tactically. Large banks appear comfortable scaling Bitcoin exposure through regulated ETFs, while treating non-BTC assets as secondary or higher risk.
Several developments warrant close attention in the coming months. First, watch other banks’ 13F filings. Peers like Morgan Stanley, JPMorgan, Wells Fargo, and Goldman have already reported material Bitcoin ETF positions. Future filings will show whether a Bitcoin-first tilt is becoming standard across the sector. Second, monitor ETF flow trends versus price action. Recent weeks have seen sizable Bitcoin ETF outflows in aggregate, even as assets under management stay high. Sustained net inflows would strengthen the case that institutions are adding on dips rather than exiting. Third, track regulation and product set evolution. New ETF launches for Bitcoin, ETH, or even staking products, along with clearer rules, can make it easier for banks to expand or rebalance their crypto exposure. If more large banks echo Bank of America’s allocation pattern, Bitcoin’s role as the institutional benchmark asset in crypto strengthens, while altcoins may remain more cycle and narrative dependent.
Bank of America’s larger IBIT position and reduced ETH and SOL ETF stakes signal a deliberate consolidation around Bitcoin as its primary crypto exposure. For crypto users, the important takeaway is not the dollar size alone, but the direction of travel. Traditional banks are increasingly accessing Bitcoin through regulated ETFs, while keeping altcoin exposure relatively small and selective. Watching future bank filings and ETF flow data will help gauge how durable this Bitcoin-centric institutional trend really is.
