U.S. spot Ethereum ETFs are wrapping up August with nearly $4 billion in net inflows, marking their second-largest monthly gain since they launched. This boost comes as Ethereum continues to outshine Bitcoin ETFs.
Additionally, data from Coinglass highlights the extent of this shift. Back in late 2024, inflows into Ethereum ETFs were quite erratic, with investors pulling out funds even while ETH was hovering around $4,000.

Despite rising prices, market confidence remained quite shaky. By February 2025, Ethereum had dipped below $2,000, and ETF outflows were on the rise. This led to increased selling pressure that affected institutional and retail sentiment.
However, everything changed dramatically by mid-2025. Starting in May, inflows surged, with institutions investing heavily in Ethereum ETFs. At the same time, ETH made a recovery, bouncing back from under $2,000 to near $4,500 by August 29.
As of August 30, Bitcoin spot ETFs experienced outflows of 1.13K BTC, yet the overall net inflows are at 594.01K BTC. The daily trading volume reached $4.66 billion, with net assets totaling $145.17 billion.
Bitcoin ETFs Show Turbulence
Meanwhile, Bitcoin spot ETFs delivered a different story. According to SoSoValue, daily inflows swung violently between surges and withdrawals. At one point, daily inflows exceeded $1 billion. However, several sessions also recorded outflows worth hundreds of millions.

On top of that, the white line on the chart indicates that Bitcoin ETF assets surged past $140 billion by the end of August. This shows that, even with all the ups and downs, Bitcoin ETFs have managed to keep their long-term growth momentum.
Particularly, Bitcoin’s price followed ETF flows closely. Since the beginning of 2024, BTC rose to exceed $110,000, which is similar to the activity inflows and outflows at the time. Thus, Bitcoin ETFs continue to influence market sentiment and liquidity.
According to data from Farside investors, Bitcoin ETFs experienced highs and lows, with BlackRock’s IBIT taking the lead by pulling in over $58 billion since its launch. On August 14, IBIT saw an inflow of more than $523 million.
But just a few days later, on August 19, investors pulled out the same amount across Bitcoin ETFs. Fidelity’s FBTC and Ark’s ARKB also faced significant fluctuations. Additionally, Grayscale’s GBTC continued to lose assets, primarily due to its 1.5% fee, while competitors charge around 0.25%.
Ethereum ETFs Show Early Enthusiasm
As for Ethereum ETFs, data from farside shows August having around $13.5 billion flowing in from various providers. According to the data, there is high demand with August 11 alone bringing in over $1 billion.
However, by mid-month, the trend reversed, and on August 19, there were nearly $430 million in outflows. As the month came to a close, the flows evened out but remained shaky, with Ethereum ETFs losing $165 million on August 29.
Analysts Highlight Broader Expansion
Bloomberg’s James Seyffart noted that Ethereum ETFs alone attracted nearly $10 billion since July, totaling almost $14 billion since inception.

Additionally, analyst Lucky pointed out that over 90 crypto ETPs now await U.S. approval, including Solana, XRP, and HBAR. Hence, regulators could open new pathways for institutional capital as early as September.
The Ethereum ETF momentum proves the institutions’ interest. Having other altcoin ETFs will likely increase the funding flowing into the digital assets.
