Market data from Farside, reported by BlockBeats on September 25, showed US Bitcoin spot ETF products recorded $190.7 million in net inflows on September 24. Ethereum spot ETF products recorded $66.1 million in net inflows over the same day. The headline demand concentrated in BlackRock's IBIT and ETHA, while several listed products saw no net movement.

Bitcoin flows concentrate in IBIT

BlackRock's IBIT absorbed $162.6 million, accounting for most of the Bitcoin ETF net inflow. Fidelity's FBTC added $12.9 million, Morgan Stanley's MSBT added $10.2 million, Franklin's EZBC added $4.9 million, and Bitwise's BITB added $4.1 million. The five inflow products together added $194.7 million, and the $4 million outflow from WisdomTree's BTCW left the $190.7 million total.

The remaining tracked Bitcoin products had no net inflow or outflow: ARK's ARKB, Invesco's BTCO, Valkyrie's BRRR, VanEck's HODL, Grayscale's GBTC and Grayscale's BTC. In other words, only one product recorded a negative flow on the day, while six products recorded no movement.

Ethereum demand narrows to three products

On the Ethereum side, BlackRock's ETHA led with $26.8 million in net inflows. Fidelity's FETH followed with $21.5 million, and Grayscale's ETH added $17.8 million. Those three products together match the reported $66.1 million total net inflow.

Other Ethereum ETF products listed by Farside showed no net flow: BlackRock's ETHB, Bitwise's ETHW, TETH from 21Shares, VanEck's ETHV, Invesco's QETH, Franklin's EZET, Morgan Stanley's MSSE, and Grayscale's ETHE. The absence of flows means these products neither added nor subtracted tracked money on September 24.

What the flow data shows

The daily figures are product-level net flow numbers, not price data or trading volume. They show where new money entered or left the tracked US spot ETF wrappers during September 24. For Bitcoin, the flow was highly concentrated in IBIT, with smaller additions spread across four other products and one modest outflow. For Ethereum, the total was smaller, but demand also narrowed to three products.

Because the source is a one-day monitoring report, the figures should be read alongside longer flow trends rather than as a standalone signal. They also do not identify whether the money came from retail accounts, institutional allocators, or other buyer types. For readers, the main takeaway is that BlackRock's products led the reported demand for both major assets on the day, while many listed products stayed flat.

The next updates will show whether this concentration persists, whether other issuers attract new inflows, or whether products that were flat continue to see no net movement.
