Why BlackRock Has Become Indispensable to Crypto ETFs

Since when can a single company make or break the weather in the crypto sphere? BlackRock, this behemoth of traditional finance, now seems to play this role with crypto ETFs. In 2025, one simple fact sums up the situation: without BlackRock, investment flows into Bitcoin ETFs would be negative. So, can this financial empire arbitrate the future of altcoins, decide the winners, and bury the losers even before kickoff?

IBIT, the massive refuge for capital seeking regulated bitcoin

The numbers don’t lie: BlackRock’s iShares Bitcoin Trust (IBIT) attracted $28.1 billion in 2025. Without it, the total Bitcoin ETFs show a negative balance of $1.27 billion. In other words, IBIT alone is pulling the crypto industry by the hair, rescuing it from worrying stagnation.

It’s not just an effect of size. It’s an effect of trust. For many institutions, BlackRock is the guarantee of exposure to bitcoin, but without the technical complexity of wallets or the volatility of crypto exchanges. Thanks to regulated management, Coinbase as custodian, and a transparent valuation method, IBIT ticks all the boxes of a model student.

Even Geoff Kendrick from Standard Chartered admits: the main part of bitcoin’s upward momentum in 2025 is fueled by these incoming flows.

So when Vetle Lunde (K33 Research) writes on X ” No BlackRock, no party“, it’s not a joke. It’s a diagnosis. This fund does not just participate: it solely supports an entire facade of institutional crypto market solidity.

Without BlackRock, will altcoins dance alone?

The next chapter will be played out with altcoin ETFs, and for once, BlackRock hasn’t reserved a front-line spot. No product announcement for Solana or XRP on the horizon. This void raises hope among some competitors… but also doubts.

JPMorgan mentions a potential of $3 to $6 billion for a Solana ETF. Bitget even targets $6 billion. These amounts are far from negligible. But be careful with comparisons. Bitcoin ETFs reached 6% adoption of BTC’s market cap in six months. For Ethereum ETFs, it’s half that.

Without BlackRock’s credibility, altcoin ETFs will have to prove themselves in a riskier market, without the backing of a globally respected brand. This could slow hesitant institutional investors. Because while IBIT reassures, nothing guarantees that alternatives for SOL or XRP will have the same safe-haven effect.

This void could certainly open the door to bold players: Fidelity, Ark Invest, or Bitwise, who wish to gain ground. But without the aura effect, these new products will likely receive less momentum, and investors won’t rush as quickly.

A BlackRock effect turned system? The balance of the crypto ecosystem in question

BlackRock currently holds about 60% of the assets of U.S. Bitcoin ETFs. It’s more than dominance; it’s a stranglehold on the image of solidity in the regulated crypto market. Yet, this power also raises a question: when a single company captures so much, what’s left for others?

The imbalance is even more striking when looking at the other side of the coin: Grayscale and its GBTC, initially seen as pioneers, have posted cumulative outflows of $24.6 billion since 2024. Even well-intentioned funds can’t keep up.

Faced with this, BlackRock’s absence in altcoins could create a strategic window. Those who dare to seize it could capture a new clientele, less attached to Wall Street giants. But trust will still need to be built.

The 5 key facts reshaping the crypto ETF landscape

• $28.1B invested in IBIT in 2025: an unmatched record;
• $92.66B assets managed by IBIT: about 4% of total BTC supply;
• Only one month of net outflows for IBIT since its launch (February 2025);
• $24.62B outflows for Grayscale: the sector’s largest retreat;
• $0 announced by BlackRock for Solana or XRP ETFs: the silence is telling.

BlackRock recently crossed the threshold of 800,000 BTC held via IBIT, further strengthening its dominant position. This figure is not just a record: it’s a signal. A reminder that institutional adoption of Bitcoin today goes through giants who know how to speak the language of Wall Street… and that of crypto.
