Bank of America Bitcoin ETFs drive Q1 cut to Ethereum, tilt to IBIT

Bank of America Bitcoin ETFs are suddenly at the center of a sharp portfolio turn, with the bank cutting back on Ethereum and Solana exposure in the first quarter while leaning harder into regulated Bitcoin products. The clearest sign of that shift is BlackRock’s iShares Bitcoin Trust, or IBIT, which has grown into the bank’s biggest crypto position.

That matters because it is not just a routine rebalance. Instead, it points to a clearer preference for Bitcoin inside a major U.S. bank’s digital-asset strategy, with spot ETFs now doing much of the work that direct crypto exposure once represented.

The filings described in recent reports sketch a simple picture. Bank of America still has exposure to several crypto-related products, but Bitcoin-linked investments now carry far more weight than Ethereum or Solana. And the bank is getting that exposure through regulated vehicles that fit more neatly into traditional finance.

Bank of America Bitcoin ETFs signal a sharper shift toward Bitcoin

In the first quarter, Bank of America reduced Ethereum and Solana exposure while increasing Bitcoin-linked investment products through spot ETFs. That combination is the core of the story.

The move suggests the bank is not exiting crypto-related investments altogether. Instead, it appears to be concentrating its exposure around Bitcoin and doing so through products that have already become a preferred route for institutions.

For investors and market watchers, the Bank of America Bitcoin ETFs story stands out beyond a single filing. It offers a snapshot of where institutional confidence may be settling: not across the entire crypto market, but around Bitcoin as the most established and regulated entry point.

Why BlackRock IBIT became the bank’s biggest crypto bet

The clearest sign of that concentration is BlackRock IBIT.

BlackRock’s iShares Bitcoin Trust (IBIT) became Bank of America’s largest crypto holding after the bank lifted its exposure to roughly $37 million. The holding represented 972,590 shares of the fund, and IBIT accounted for nearly 70% of the bank’s crypto investment portfolio.

That is a striking level of concentration. When a single spot Bitcoin ETF makes up nearly 70% of a bank’s crypto portfolio, it signals more than passive interest. It shows a deliberate tilt toward one asset, one wrapper, and one kind of risk profile.

What the portfolio mix says about institutional crypto exposure

Regulated Bitcoin vehicles are increasingly becoming the institutional bridge between Wall Street and crypto. Rather than spreading capital evenly across Bitcoin, Ethereum, Solana, and other digital assets, Bank of America appears to be treating Bitcoin as the primary institutional-grade exposure.

That is important because it also helps explain why the bank’s Ethereum holdings reduced while Bitcoin-linked products gained ground. In practice, the portfolio points to a narrower but more focused view of institutional crypto exposure.

What else sits in Bank of America’s crypto portfolio

The bank’s crypto-related portfolio did not revolve around IBIT alone, even if it dominated the mix.

Bank of America also held positions tied to Fidelity’s FBTC, Bitwise’s BITB, and Grayscale Bitcoin products, according to the report. However, none matched the scale of its IBIT allocation.

At the same time, the filing reflected cuts to Ethereum-linked allocations and reductions in Solana-related investment products. Smaller holdings connected to XRP and Solana ETFs were also mentioned, though those allocations remained limited.

Another major piece of the broader Bitcoin picture sits outside ETFs. Bank of America also held nearly 3.96 million shares of MicroStrategy, a stake valued at roughly $660 million. Because MicroStrategy is closely associated with a Bitcoin treasury strategy, that investment adds another layer of Bitcoin-linked exposure.

• less emphasis on Ethereum and Solana
• more weight in Bitcoin exposure through spot ETFs and MicroStrategy

A broader Wall Street shift toward regulated Bitcoin products

Bank of America’s repositioning fits a wider trend among large financial firms increasing institutional crypto exposure through regulated products.

The report says other major banks are also building Bitcoin exposure this way. Morgan Stanley, Goldman Sachs, and JPMorgan were all cited as part of that broader movement toward spot crypto ETFs and related products.

That wider context is important. The Bank of America Bitcoin ETFs shift is notable on its own, but it becomes more meaningful when viewed as part of a Wall Street pattern. Large banks do not need to embrace every corner of crypto for the market to change. A concentrated move into Bitcoin through ETFs is enough to reshape where capital goes, which products win scale, and which assets get treated as institutional priorities.

It also helps explain why Bitcoin-linked products are drawing more attention than diversified crypto bets. For traditional firms, spot ETFs offer a familiar structure, easier reporting, and a regulated way to gain market exposure without stepping too far outside existing frameworks.

For now, that appears to be where the momentum is. Bank of America trimmed Ethereum holdings, cut Solana exposure, and made IBIT the centerpiece of its crypto portfolio — a choice that says as much about Wall Street’s comfort zone as it does about crypto’s pecking order.
