Summary
U.S. spot bitcoin exchange-traded funds added $137.33 million on Wednesday, according to the report, extending their inflow streak to three sessions. Week-to-date additions now total roughly $423.66 million, following $110.34 million on Monday and $175.99 million on Tuesday. The three consecutive positive sessions follow a week in which the previous period ended with two sizable withdrawals.

Blackrock's IBIT supplied almost the entire Wednesday amount with $136.01 million, while Bitwise's BITB contributed $1.32 million. Monday's $110.34 million inflow also came entirely through IBIT, and Fidelity joined the buying on Tuesday, but Wednesday's demand again centered almost exclusively on Blackrock. Trading value eased to $1.26 billion, the lowest of the week so far, while net assets rose to $104.88 billion. The report notes that a broader return of inflows across Fidelity, Bitwise and other issuers would make the trend more durable.

Bloomberg ETF analyst James Seyffart estimates the average primary-market cost basis of U.S. bitcoin ETF creations at just under $82,000 and the funds' collective holdings at roughly 1.3 million bitcoin. Seyffart describes this as a rough gauge only, since secondary-market trading prevents a precise estimate of what current holders paid.

Ether ETFs lost $21.41 million on Wednesday, extending their weekly outflow streak but improving in pace. Monday's loss was $88.58 million and Tuesday's was $60.22 million, bringing the three-session total to about $170.21 million. Blackrock's ETHA was the only Wednesday outflow at $44.83 million, while Fidelity's FETH attracted $18.78 million, Grayscale's Ether Mini Trust added $3.62 million and Morgan Stanley's MSSE brought in $1.02 million. Ether ETF trading activity reached $480.72 million, with net assets closing at $14.27 billion.

Solana ETFs lost another $5.66 million, entirely through Bitwise's BSOL, bringing the category's decline to roughly $33.05 million since Monday. Wednesday's outflow was smaller than Tuesday's $19.16 million exit. Grayscale's ZCSH attracted $2.07 million, extending Zcash's inflow streak to seven sessions and bringing weekly additions to about $7.48 million. HYPE, NEAR and XRP recorded no net flows on Wednesday.

The report characterizes the emerging pattern as one of persistence: bitcoin has posted three positive sessions, ether withdrawals are slowing, and Solana selling has eased from Tuesday's peak. If those trends hold through Thursday, the week could show a clearer separation between assets regaining institutional sponsorship and those still working through October's risk reduction.
