The spot Bitcoin ETF market has experienced unprecedented momentum, with inflows exceeding $3 billion in a single week in April 2025, marking the second-largest net inflow on record for these investment vehicles.12 This surge represents a significant turnaround after five weeks of inconsistent flows, resulting in approximately $2.26 billion in net inflows for the month.2 BlackRock's iShares Bitcoin Trust (IBIT) continues to dominate the market with over $56 billion in assets under management, accounting for roughly 3% of Bitcoin's circulating supply.1

The robust institutional interest is particularly evident in the daily performance metrics, with April 22 and April 23 seeing massive single-day inflows of $936 million and $916 million respectively.1 This institutional enthusiasm has pushed the total assets under management for Bitcoin ETFs to $109 billion, with BlackRock and Fidelity emerging as the dominant players controlling the majority of market share.13 Analysts attribute this surge to Bitcoin's recent decoupling from traditional risk assets like U.S. stocks and gold, as well as rising geopolitical tensions that have enhanced Bitcoin's appeal as a safe-haven investment.1

BlackRock's iShares Bitcoin Trust (IBIT) has established itself as the undisputed leader in the spot Bitcoin ETF market, now controlling approximately 50% of the total assets under management across all U.S. Bitcoin ETFs with over $56 billion AUM.1 This remarkable growth has made IBIT the most successful ETF launched in the past decade, accumulating $36.3 billion in net inflows in just 11 months.2 The fund recently surpassed 500,000 BTC in holdings and is on track to potentially reach 1 million BTC, equivalent to about 5% of Bitcoin's total supply.3

IBIT's dominance is evident in its daily performance, consistently capturing the lion's share of Bitcoin ETF inflows. Recent data shows IBIT recording substantial single-day inflows, including $643.16 million on April 234, $327.3 million on April 245, and $240.1 million on April 26.6 This institutional interest has been further solidified by BlackRock's strategic decision to incorporate IBIT into its $150 billion model portfolio universe with a 1-2% allocation, potentially opening new avenues of demand.78 As BlackRock CEO Larry Fink noted, "IBIT is the fastest-growing ETF in the history of ETFs," demonstrating how these products have improved access to Bitcoin exposure for new capital sources and contributed significantly to Bitcoin's push to new all-time highs.3

The Bitcoin Power Law Theory, developed by physicist Giovanni Santostasi, suggests that Bitcoin's price follows a predictable mathematical pattern over time rather than moving randomly.1 When plotted on logarithmic scales, Bitcoin's price history forms a consistent power curve with defined support and resistance bands that have contained price movements throughout its existence.2 This model uses the formula "Estimated Price = A * (days from Genesis Block)^n" where n equals approximately 5.8.3

Current power law projections point to significant price targets for Bitcoin's future. Analysts using this model predict Bitcoin could reach $170,000-$200,000 by late 2025 or early 2026.45 The model also suggests a price floor of approximately $30,000 that should never be breached again, with Bitcoin potentially reaching $1 million between 2028 and 2037.2 Unlike other prediction models that have been invalidated, the Power Law has maintained its reliability, making it a preferred framework for long-term Bitcoin investors to understand market cycles and potential price trajectories.26
