BlackRock IBIT Adds 118,000 BTC Driving 124,000 BTC Spot ETF Growth

BlackRock's IBIT ETF has significantly increased its Bitcoin holdings, adding 118,000 BTC since April 2025. This substantial growth has been a key driver in the overall increase of spot Bitcoin ETFs, which saw a total addition of 124,000 BTC over the same period. The total BTC held by U.S. spot ETFs, excluding GBTC, rose from 932,000 to 1,056,000 BTC over 87 days, averaging approximately 1,430 BTC added daily. BlackRock IBIT's contribution of around 118,000 BTC underscores its leading role in the expanding spot BTC ETF market.

The consistent inflows into spot Bitcoin ETFs, particularly BlackRock IBIT, reflect the growing institutional interest in Bitcoin. BlackRock IBIT recorded a net inflow of $1.31 billion in a single week, with June 24 marking its highest daily inflow at $436.3 million. This steady inflow indicates that investor interest in Bitcoin ETFs is not a temporary trend but a sustained phenomenon, highlighting the expanding role of ETFs in providing access to Bitcoin markets.

The concentration of Bitcoin holdings among a few large ETFs is another notable trend. BlackRock IBIT holds over 673,000 BTC, the largest amount among spot BTC ETFs. Fidelity’s FBTC follows with more than 302,000 BTC, and GBTC holds close to 185,000 BTC. Together, these three funds control a significant share of ETF-held BTC, reflecting the dominance of major asset managers in the ETF-based Bitcoin investment landscape. This concentration could influence how smaller funds enter or compete within this space, potentially narrowing the field of control among Bitcoin ETF offerings.

Recent on-chain trends among long-term holders (LTHs) and short-term holders (STHs) mirror patterns observed in past bull markets. Historically, LTHs have increased their share before significant price rallies. For instance, during the period when Bitcoin climbed from $28,000 to $60,000, and later from $60,000 to $100,000, LTHs grew their holdings. This accumulation pattern suggests that current market positioning may be preparing for a major upward movement. With Bitcoin near $100,000, LTHs are again increasing their share relative to STHs, a trend that has continued for several weeks. While historical trends do not guarantee future price action, they provide valuable insights into potential market movements. Analysts have used these patterns to highlight risk-aware forecasting methods, suggesting a possible price target of $160,000 based on earlier bull-cycle multipliers. However, it is important to note that these projections are speculative and not guaranteed outcomes.
