In early July 2025, U.S. spot Bitcoin 
$77,464 ETFs experienced unprecedented popularity, witnessing net inflows that surpassed the billion-dollar mark over just two days. This influx, which reversed a $342.2 million outflow from the previous Tuesday, highlights growing investor interest and confidence in these financial instruments. The total net inflows recorded have approached $50 billion since their inception, with assets under management nearing $128 billion.
Record-Breaking ETF Inflows
Data from SoSoValue indicates that the fresh $1 billion inflow on Wednesday and Thursday extended a 15-day streak of positive flows totaling $4.7 billion. During these dynamic market days, Fidelity’s FBTC fund emerged as a leader, attracting $184 million and $237.1 million on each respective day.
Thursday’s trading volume reached 5.3 billion dollars, marking the highest level since May. A significant portion, $4.1 billion, was contributed by BlackRock’s IBIT ETF. Consequently, the total trading volume of spot ETFs exceeded $1 trillion, increasing their market share in the spot Bitcoin arena to 28%.
BlackRock Leads the Pack
The IBIT fund, managed by BlackRock, reached an impressive $73.6 billion in assets and has only faced one month of net losses since its launch in January 2024. Outperforming the S&P 500 ETF in commission revenue, it ranks third among BlackRock’s 1,197 funds.
A fresh $224.5 million inflow on Thursday revitalized the fund after early July stagnation, leaving it just $9 billion short of its peak.
Potential Altcoin Rally
On the same day, spot Ethereum 
$2,315 ETFs received inflows of $148.5 million, while a recently launched Solana 
$86 staking ETF saw $11.4 million. BRN analyst Valentin Fournier noted that Bitcoin’s dominance in the market rose to 64.6%, a historical precursor to altcoin rallies.
The analyst suggested that if Bitcoin’s price remains steady at its peak, market attention could shift towards altcoins, providing hope to cryptocurrency investors seeking market diversification.
