US-listed spot Bitcoin exchange-traded funds (ETFs) have seen a significant uptick in investor confidence, with a seven-day streak of inflows totaling nearly $2.9 billion. This surge in activity signals a strong return of investor interest following a selloff in August.
According to data from Coinperps, Bitcoin ETFs pulled in $292.27 million on Sept. 16 alone, contributing to the total inflows of $2.87 billion over the past week. This reversal in fortunes stands in stark contrast to the previous month, when these products experienced outflows of over $750 million as investors shifted towards Ethereum-based ETFs.
The momentum behind Bitcoin ETFs is more than just a short-term trend. Bitwise has highlighted that these US-traded ETFs are now absorbing more capital than the new Bitcoin supply entering the market, underscoring the ongoing recovery. NovaDius Wealth Management President Nate Geraci emphasized the scale of this trend, noting that Bitcoin ETFs have attracted over $22 billion in inflows since January.
This resurgence in Bitcoin ETFs comes as Ethereum-focused products lose steam in the market. In August, investors allocated approximately $3.87 billion into Ethereum ETFs, while Bitcoin products struggled to attract capital. However, in September, Bitcoin ETFs have already garnered $3.14 billion in inflows compared to just $148 million for Ethereum. Last week, BTC ETFs saw inflows of $2.4 billion globally, outpacing Ethereum’s $646 million.
The renewed interest in Bitcoin ETFs is driven by growing institutional conviction. Regulatory clarity efforts and an expanding lineup of large financial institutions offering Bitcoin access are seen as key catalysts for this trend. For instance, Bitwise CEO Hunter Horsley revealed that a major US bank, with assets exceeding $1 trillion, has partnered with Bitwise as an asset manager. Additionally, the Bitwise Bitcoin ETF (BITB) has received approval for use in managed accounts and brokerage platforms serving over 10,000 wealth managers.
This increased adoption has bolstered the overall market performance of BTC ETFs. Data from Ecoinometrics shows that two BTC ETFs now rank among the top 100 by assets under management, collectively holding $110 billion. BlackRock’s IBIT, the largest of these funds, is closing in on SPDR Gold Shares (GLD), a traditional benchmark for safe-haven investing.
In conclusion, the recent surge in inflows into US-listed spot Bitcoin exchange-traded funds reflects a renewed confidence among investors, driven by institutional support and regulatory clarity. This trend highlights the growing prominence of Bitcoin as a mainstream investment asset and underscores the ongoing evolution of the cryptocurrency market.
