During the trading week of September 14‑18, U.S. spot crypto exchange‑traded products (ETPs) experienced a combined net outflow of approximately $70.7 million. The flow dynamics varied sharply across the four tracked asset categories.

Bitcoin ETFs rebound after mid‑week redemptions

Spot Bitcoin ETFs ended the week with a net inflow of $6.1 million, driven by a $433 million inflow on Friday that offset earlier large withdrawals. BlackRock’s IBIT led with $120.6 million of weekly inflows, followed by Fidelity’s FBTC with $79.9 million. Withdrawals were recorded from ARK 21Shares’ ARKB ($141.9 million) and Grayscale’s GBTC ($62.3 million).

Ether ETFs register the largest weekly outflow

Ether‑focused spot ETFs posted a net outflow of about $140.6 million, the weakest performance among the four categories. Despite a $143.7 million inflow on Friday, the week’s withdrawals totaled $405.4 million across Monday‑Thursday. BlackRock’s ETHA contributed a $56.1 million net outflow, while Fidelity’s FETH and Bitwise’s ETHW also posted sizable redemptions.

Solana ETFs attract $60.7 million, led by Bitwise

Solana‑linked ETFs recorded net inflows of $60.7 million, the strongest total among the four assets. The bulk of the weekly inflow—$47.6 million—went to Bitwise’s BSOL on Friday, accounting for roughly 97 % of the category’s intake.

Hyperliquid ETFs post modest gains

Hyperliquid‑related ETFs ended the week with a net inflow of $3.1 million after a mixed series of daily flows. Bitwise’s BHYP and 21Shares’ HYPG contributed the positive movements.

Contextual market factors

The flow patterns unfolded alongside a volatile macro environment, including a 25‑basis‑point Federal Reserve rate hike and Bitcoin’s return above $80,000 later in the week.
