US spot Bitcoin ETFs sustain 'Uptober' inflows
Spot Bitcoin exchange-traded funds in the United States extended their October rally, recording a combined $2.71 billion in net inflows for the week as institutional interest in Bitcoin — often called "digital gold" — remains robust. Data tracked by SoSoValue show total assets under management for these ETFs reached $158.96 billion by Friday, equal to roughly 7% of Bitcoin's overall market capitalization.
Weekly flow breakdown and AUM
Monday proved to be the strongest single day of the week for spot Bitcoin ETFs, with funds drawing an unusually large $1.21 billion in net purchases — the second-largest daily inflow since the launch of these products. Tuesday followed with another $875.61 million of inflows as asset allocators continued to add exposure.

Spot Bitcoin ETFs see weekly inflows.
“Capital keeps flowing into BTC as allocators double down on the digital gold conviction trade. Liquidity is building now as the market momentum takes shape,” said Vincent Liu, chief investment officer at quantitative trading firm Kronos Research. Investors tracking inflows see the pattern as evidence that institutional demand is strengthening Bitcoin’s market structure.
Market jitter: tariff headlines cause modest outflow
Late-week macro headlines briefly interrupted the stream of inflows. On Friday, Bitcoin ETFs registered a modest $4.5 million net outflow following President Donald Trump’s announcement of a proposed 100% tariff on imports from China. Market participants described the reaction as a short-term sell-the-news move rather than a shift in long-term conviction.
Among major products, BlackRock’s IBIT led daily inflows with $74.2 million and now holds about $65.26 billion in cumulative assets. Fidelity’s FBTC and Grayscale’s GBTC both experienced outflows on Friday of $10.18 million and $19.21 million, respectively. Analysts noted that headline-driven volatility can produce quick outflows even while institutional allocation trends remain intact.

ETF filings surge as 'Uptober' heats up
The ETF momentum coincides with a wave of filings: 31 crypto ETF applications were submitted to the U.S. Securities and Exchange Commission over the last two months, including 21 filings in the first eight days of October alone. Market watchers, including Bloomberg analyst James Seyffart, have pointed out that nearly 100 crypto-related products were awaiting SEC decisions as of late August — suggesting the potential for a broader expansion of U.S. crypto ETFs.
For traders and long-term investors, the current inflow trend underscores growing institutional demand for spot Bitcoin exposure via regulated ETF wrappers. While macro headlines can cause short-term wobble, many allocators view the flow data as confirmation that adoption is progressing and liquidity is building.
