What percentage of Bitcoin is owned by BlackRock?
BlackRock’s entry into the Bitcoin market through the iShares Bitcoin Trust (IBIT) has marked a new era in institutional Bitcoin accumulation.
Since its launch on Jan. 11, 2024, IBIT has grown at a pace that few expected, and no other ETF has matched. As of June 10, 2025, BlackRock holds over 662,500 BTC, accounting for more than 3% of Bitcoin’s total supply. At today’s prices, that’s $72.4 billion in Bitcoin exposure, a staggering figure by any measure.
For comparison, it took SPDR Gold Shares (GLD) over 1,600 trading days to reach $70 billion in assets under management. IBIT did it in just 341 days, making it the fastest-growing ETF in history. In addition to being a milestone for BlackRock itself, this fact also shows us how deeply institutional interest in Bitcoin has matured.
BlackRock’s Bitcoin holdings now eclipse those of many centralized exchanges and even major corporate holders like Strategy. In terms of raw Bitcoin ownership, only Satoshi Nakamoto’s estimated 1.1 million BTC outnumbers IBIT, and that lead is narrowing.
If inflows continue at the current pace, IBIT may eventually become the single largest holder of Bitcoin, a major change for Bitcoin supply distribution and ownership concentration.
BlackRock Bitcoin accumulation over time
Did you know? Coinbase Custody, not BlackRock, holds the private keys for the BTC in IBIT, safely storing client assets offline and backed by commercial insurance.
Why is BlackRock betting big on Bitcoin in 2025?
Behind BlackRock’s massive allocation is a strategic shift in how it views Bitcoin: as a legitimate component of long-term, diversified portfolios.
The BlackRock Bitcoin strategy
BlackRock’s internal thesis embraces Bitcoin’s volatility as a tradeoff for its potential upside. With IBIT, they’re betting that broader adoption will stabilize the asset over time, improving price discovery, increasing liquidity and narrowing spreads.
In this view, Bitcoin is a long-term play on monetary evolution and digital asset infrastructure.
This philosophy (coming from the world’s largest asset manager) sends a strong signal to peers. It reframes the conversation around institutional adoption of Bitcoin, shifting it from “whether” to “how much” exposure is appropriate.
The investment case for institutional Bitcoin accumulation
BlackRock highlights several factors that make Bitcoin appealing in 2025:
- Scarce by design: With a hard cap of 21 million coins and a halving-based issuance model, Bitcoin scarcity mirrors gold, but with a digital backbone. Some estimates suggest a meaningful share of existing coins are lost or inaccessible, making the effective supply even tighter.
- Alternative to dollar-dominance: With growing sovereign debt and geopolitical fragmentation in mind, Bitcoin’s decentralized nature offers a hedge against fiat risk. It’s positioned as a neutral reserve asset, resistant to government overreach and monetary manipulation.
- Part of the broader digital transformation: BlackRock views Bitcoin as a macro proxy for the shift from “offline” to “online” value systems, from finance to commerce to generational wealth transfer. In their words, this trend is “supercharged” by demographic tailwinds, especially as younger investors gain influence.
Put together, these factors provide distinct risk-return characteristics that traditional asset classes can’t replicate. BlackRock’s framing (that Bitcoin offers “additive sources of diversification”) makes a compelling case for its integration into mainstream portfolios.
BlackRock crypto portfolio integration
BlackRock advocates a measured approach, 1% to 2% exposure within a traditional 60/40 stock-bond mix. This may sound small, but in a portfolio of institutional scale, it’s enough to generate impact and normalize Bitcoin exposure for conservative allocators.
They also benchmark Bitcoin’s risk profile against high-volatility equities, like the “Magnificent Seven” tech stocks, to demonstrate how it can fit within standard portfolio models.
Did you know? Unexpected by-products (“dust”) from Bitcoin transactions within IBIT have included tiny amounts of other tokens. BlackRock keeps these in a separate wallet or donates them to charity, avoiding tax complications.
BlackRock Bitcoin ETF impact
BlackRock’s decision to accumulate over 3% of Bitcoin’s total supply through its iShares Bitcoin Trust (IBIT) is a turning point for how Bitcoin is perceived, traded and regulated.
Bitcoin has always been known for its volatility, driven by fixed supply, shifting sentiment and regulatory uncertainty. Historically, the relatively thin liquidity of crypto markets made large trades highly impactful. Now, with…
