Bitcoin ETFs add $31.07 million as streak reaches eight sessions

What happened

Bitcoin ETFs in the U.S. added $31.07 million on Sept. 28, their eighth straight positive session, taking cumulative inflows over that stretch to roughly $3 billion. Blackrock's IBIT led the day with $54.84 million, and Grayscale's Bitcoin Mini Trust added $10.32 million. Grayscale's GBTC lost $23.19 million and Fidelity's FBTC recorded a $10.90 million outflow. Trading volume reached $2.05 billion and net assets closed at $107.82 billion.

Bitcoin's price slipped to a weekly low above $82,500 on Monday, then climbed back above $84,000 in the afternoon, E.T. time. A report published the next day counted a ninth session, with SoSoValue logging $66.19 million in net inflows on Sept. 29, led by IBIT at $51.09 million.

Ether ETFs stayed positive for a seventh straight session, drawing roughly $17.1 million. Solana ETFs pulled in $12.70 million and XRP ETFs $3.96 million, all of the latter through Canary's XRPC. Zcash went the other way, as Grayscale's ZCSH recorded an $8.12 million outflow, and HYPE ETFs saw no net flows.

Why it matters

The daily figure is well below the prior week's total. Bitcoin ETFs attracted $2.39 billion in the week before, their best weekly showing since October 2025. Lacie Zhang, research lead at Bitget Wallet, said U.S. spot bitcoin ETFs remain net buyers even as daily inflows slowed from nearly $1 billion at the start of the previous week to $31 million on Monday.

The funds are also reaching mainstream advice channels. Bloomberg senior ETF analyst Eric Balchunas said they unlock about $40 trillion in advisory assets, and argued that issuers such as Blackrock and Fidelity have made bitcoin exposure easier for financial advisers, many of whom begin with modest allocations.

Year-to-date flows have turned positive. Annual net inflows have reached approximately $1 billion, reversing the $5 billion deficit recorded at July's close, while Bitcoin has gained 43.1% in Q3 2026 so far.

What the data shows

• The Sept. 28 session added $31.07 million, with $2.05 billion in trading volume and $107.82 billion in net assets.
• Ether ETFs drew roughly $17.1 million, Solana ETFs $12.70 million and XRP ETFs $3.96 million, while Zcash funds lost $8.12 million. A later tally showed $2.81 million in net outflows from ether funds on Sept. 29.
• Bitcoin traded at $83,259.79 on Sept. 30, and the wider crypto market lost 0.98% over 24 hours, cutting total capitalization to $2.85 trillion.
• Demand from bitcoin accumulator addresses has reached a record high, according to CryptoQuant data cited in the second report.

What is still unclear

• The two reports count the streak differently: eight sessions through Sept. 28 in one, and nine trading sessions through Sept. 29 in the other.
• Their daily totals also come from different providers, with $31.07 million reported for Sept. 28 and $66.19 million for Sept. 29.
