Institutional Demand Spikes as BlackRock Increases Crypto Holdings
According to Crypto Rover, BlackRock has purchased $496.8 million worth of Bitcoin (BTC) and $394.9 million in Ethereum (ETH). The combined $891.7 million purchase underscores a sharp uptick in institutional appetite as both spot Bitcoin and Ethereum exchange-traded funds (ETFs) post multi-day inflow streaks.

On July 18, Wu Blockchain reported that Bitcoin ETFs saw net inflows of $363 million. It marked the 12th straight day of inflows, reflecting consistent demand for exposure to Bitcoin through regulated vehicles. Ethereum ETFs followed closely with $402 million in daily inflows, pushing their streak to 11 consecutive days.
The latest surge suggests whales reaccumulate digital assets as broader macro sentiment steadies.
Bitcoin ETF Inflows Extend Winning Streak
The 12-day inflow streak into spot Bitcoin ETFs reflects persistent buying interest among large institutions. These flows have continued even as BTC trades below its all-time high. Despite short-term volatility, funds are positioning for a longer-term upside.

The $363 million in inflows recorded on July 18 adds to a growing July tally that reflects the strongest demand since March. As reported by Wu Blockchain, this is the longest consistent ETF inflow stretch since the Bitcoin ETFs launched in Jan. 2024.
Data from Farside Investors, though not included directly, historically supports this trend of ETF demand aligning with major institutional purchases.
Ethereum ETFs Match Momentum with $402M Daily Inflow
Ethereum has also attracted renewed attention from institutional investors. Spot Ethereum ETFs posted $402 million in inflows on July 18, their 11th straight day of gains. While still new to the market compared to Bitcoin ETFs, Ethereum’s streak reflects strong confidence in the asset post-ETF approval.
Ethereum’s demand has accelerated since the United States Securities and Exchange Commission approved multiple spot ETH ETFs in late June. Though trading began only recently, the momentum has quickly built.
According to earlier figures, Ethereum ETFs saw more than $1.4 billion in cumulative inflows during the first two weeks of activity. The $402 million daily spike signals that interest remains high.
Market Reaction and Whale Accumulation
The crypto community interpreted BlackRock’s dual purchase as a bullish signal. “WHALES ARE LOADING UP!” Crypto Rover posted on X, sharing the $891.7 million acquisition. Market sentiment mirrored that message across several posts as users flagged the ETF flows and institutional accumulation.

While price reaction remained muted, Bitcoin stayed above $65,000 during the session, and Ethereum hovered just below the $3,500 level.
The accumulation trend aligns with prior behavior seen during earlier ETF inflow periods. Institutional investors typically avoid sharp market moves, preferring to build positions steadily—an approach likely playing out again.
BlackRock’s Strategy Reflects Long-Term Conviction
BlackRock’s move is its largest crypto-related purchase since the approval of Ethereum ETFs. The asset manager oversees more than $10 trillion in assets and continues to anchor institutional involvement in the crypto sector.
The timing of the purchase, amid consecutive daily ETF inflows, suggests BlackRock anticipates further inflows and potentially higher prices ahead. However, the firm has not issued a public statement confirming the rationale behind this week’s acquisitions.
Still, the $496.8 million Bitcoin allocation and $394.9 million Ethereum addition signal that asset managers remain focused on building crypto exposure via ETF and direct custody routes.
Outlook: ETF Flows Suggest Institutions Are Not Done Yet
Institutional demand appears far from over. With Bitcoin ETF inflows persisting for 12 straight days and Ethereum following closely, the momentum favors continued accumulation. Analysts will watch closely for whether inflows extend into a third week.
The combined $765 million in one-day inflows across BTC and ETH products on July 18 marked one of the largest daily totals since early spring.
While broader market volatility remains a risk, data from July indicates that institutions continue to treat digital assets as part of their long-term portfolios, not just a short-term trade.
Whether this trend holds through the remainder of Q3 depends on macro conditions, interest rate sentiment, and major regulatory shifts. For now, the whales seem to be back.
