BTC and ETH ETFs See Nearly $620M in Inflows on Monday
BTC and ETH platform-traded funds (ETFs) attracted a surge of inflows on Monday, highlighting growing institutional demand for digital assets through regulated investment vehicles. According to flow data, U.S.-listed spot BTC ETFs registered net inflows of $259.9 million, while ETH ETFs pulled in $359.7 million. Combined, nahead $620 million entered crypto-linked ETFs in a single trading day, underscoring the appetite for exposure to the two largest digital assets.
BlackRock’s funds once again played a central role in the day’s performance. The iShares BTC Trust (IBIT) recorded $261.8 million in net inflows, more than covering the $18.8 million in outflows from the ARK 21Shares BTC ETF (ARKB). Fidelity’s Wise Origin BTC Fund (FBTC) contributed an additional $7.5 million, though it trailed BlackRock’s dominance by a wide margin.
ETH ETFs recorded even stronger inflows, led by BlackRock’s iShares ETH Trust (ETHA), which brought in $363.2 million on its own. Grayscale’s converted ETH Trust (ETHE) logged $10 million in inflows, continuing to show traction among investors despite the higher fees associated with its products. Fidelity’s ETH ETF (FETH), however, saw $13.5 million in outflows, reflecting the volatile and competitive dynamics of the space.
Sustained Weekly Momentum
The robust daily flows extend a broader trend of steady accumulation by institutional investors. For the week ending September 12, spot BTC ETFs drew $2.34 billion in net inflows, marking the third straight week of significant gains. ETH ETFs also saw strong participation, with $638 million in net inflows, driven primarily by BlackRock and Fidelity offerings. These figures point to consistent interest in digital asset exposure as portfolio allocations expand beyond traditional asset classes.
Market strategists suggest that the growing adoption of crypto ETFs underscores a shift in perception toward digital assets. Once considered highly speculative, BTC and ETH are increasingly being treated as investable asset classes suitable for long-term institutional strategies. The presence of large, regulated issuers like BlackRock and Fidelity has only strengthened this narrative, providing investors with familiar, transparent vehicles to gain exposure.
The inflows also mirror broader optimism in crypto markets, with BTC trading near multi-month highs and ETH viewing heightened activity linked to staking and decentralized finance ecosystems. As regulatory clarity improves and product diversity expands, ETF flows are expected to remain a strong barometer of institutional sentiment.
BlackRock’s Dominance Across Products
BlackRock’s role in the market cannot be overlooked. With IBIT and ETHA consistently posting some of the largest daily inflows, the firm has cemented itself as the leading provider of crypto ETFs. Its dominance has been reinforced by strong brand recognition, competitive fee structures, and growing trust from institutional allocators.
The scale of inflows suggests that institutional investors increasingly favor BlackRock’s offerings over smaller competitors. While issuers such as ARK and Grayscale continue to play meaningful roles, the gap in flows demonstrates the concentration of capital around the largest providers.
Looking ahead, analysts believe that ETF flows will continue to influence broader crypto market dynamics. Sustained inflows not only validate digital assets as part of mainstream investment strategies but also provide additional liquidity and stability to the market. If these trends persist, BTC and ETH ETFs could play a pivotal role in bridging traditional finance with the evolving digital asset ecosystem.
