Institutional buying through ETFs fueled the rally amid rising optimism.
U.S. spot Bitcoin exchange-traded funds (ETFs) saw the second-largest single-day inflows on Monday as Bitcoin surged to a record high above $126,000.
Data from Farside Investors shows that 11 U.S.-listed spot Bitcoin ETFs collectively drew about $1.19 billion in a single day, trailing only the $1.37 billion inflow recorded on November 7, 2024, after Donald Trump’s presidential election victory.
Monday’s large inflows brought total inflows for October to $3.47 billion in just four trading days.
Bloomberg ETF analyst James Seyffart noted on X that spot Bitcoin ETFs have accumulated roughly $60 billion in inflows since their launch last year, underscoring sustained institutional interest in gaining exposure to Bitcoin.
BlackRock Dominates ETF Inflows
BlackRock’s iShares Bitcoin Trust (IBIT) led Monday’s inflows with $970 million.
The fund has attracted $2.6 billion since the start of October and is approaching a major milestone.
Nate Geraci, president of Nova Dius, said IBIT is nearing $100 billion in assets under management (AUM), holding approximately 783,767 BTC worth about $98.5 billion in Bitcoin and cash.

“The Vanguard S&P 500 ETF took more than 2,000 days to reach $100 billion in assets, while IBIT is close to doing it in about 450 days,” Geraci noted, emphasizing the unprecedented accumulation of capital.
He added that only 18 of the roughly 4,500 ETFs trading have AUM exceeding $100 billion.
Other major beneficiaries included the Fidelity Wise Origin Bitcoin Fund (FBTC) with $112 million in inflows, Bitwise Bitcoin ETF (BITB) with $60 million, and Grayscale Bitcoin Mini Trust (BTC) with $30 million.
Institutional Momentum and a “Flight to Non-Government Assets”
Bitcoin’s rally has been heavily supported by institutional participation through ETFs, allowing large investors to gain exposure without direct custody.
Analysts suggest retail participation remains limited, highlighting the dominant role of institutional capital in the current rally.
The recent surge also benefited from what traders describe as a “flight to non-government assets,” a shift toward assets like Bitcoin and gold amid a U.S. government shutdown that delayed key economic data and increased policy uncertainty.
The move into Bitcoin reflects broad investor demand for protection against possible monetary easing and rising inflation pressures.
Bitcoin Holds Near Record High
After reaching an intraday record of $126,186 on Monday, Bitcoin pulled back slightly as some investors took profits but remained resilient.
On Tuesday, the cryptocurrency traded around $123,427.90.
U.S. spot Bitcoin ETFs posted net inflows of $3.2 billion for the week ending October 3, marking the second-largest weekly intake since the funds launched, including $985 million on October 3 alone.
Seasonal optimism—commonly referred to as “Uptober”—also contributed to the market’s strength.
Historically, October has been a robust month for Bitcoin, and investors appeared to be positioning accordingly.
Despite the modest pullback, analysts noted that the convergence of ETF demand, macroeconomic uncertainty, and seasonal strength continues to reinforce Bitcoin’s upward trajectory.
