U.S. crypto ETFs delivered substantial inflows during the week ending September 25. Bitcoin funds led the way with $2.39 billion in net inflows, their strongest weekly performance since October 2025. Ether funds attracted $689.88 million, while solana, XRP, zcash, and HYPE ETFs all finished the week with net gains.
Bitcoin ETF Inflows Sustain Through Price Pullback
Capital entered bitcoin funds on each of the five trading days, even as bitcoin's price retreated from around $87,000 later in the week. This consistency marked the strongest weekly bitcoin ETF inflow since October 2025.
Monday produced the largest single-day inflow with $998.95 million, the largest bitcoin ETF inflow of 2026 and the ninth-largest on record. Tuesday added $714.75 million. Wednesday brought $346.98 million, Thursday added $190.65 million, and Friday finished with $134.47 million.
Blackrock's IBIT led the week with $1.16 billion in inflows. Fidelity's FBTC attracted $701.6 million, Ark & 21Shares' ARKB added $294.7 million, and Morgan Stanley's MSBT drew $203.3 million. Wisdomtree's BTCW was the only major bitcoin fund to finish negative, losing $4 million.
Broader Crypto Demand Emerges
Ether ETFs recorded $689.88 million in net inflows, recovering momentum after losing $140 million the previous week. Solana ETFs attracted $188.22 million during the week, representing nearly 10 percent of the category's asset base of $1.96 billion.
XRP ETFs collected $75.59 million for the week, zcash ETFs attracted $35.17 million, and HYPE ETFs finished with $9.25 million.
Year-to-Date Flows Turn Positive
The $2.39 billion haul marked a dramatic acceleration from the previous week, when bitcoin ETF flows were essentially flat. It helped push 2026 year-to-date flows back into positive territory, with roughly $4.6 billion entering U.S. spot bitcoin ETFs since August 19.
ETF analyst James Seyffart noted that the average ETF investor's estimated cost basis sits around $82,000, and that flow and regulatory-filing data suggest longer-term allocators have generally continued building positions.
