U.S.-based spot Bitcoin exchange-traded funds (ETFs) saw $388.3 million in inflows on Wednesday, marking eight consecutive days of positive capital movement, despite early market jitters stemming from the ongoing Israel-Iran conflict.
BlackRock’s iShares Bitcoin Trust (IBIT) and Fidelity’s Wise Origin Bitcoin Fund (FBTC) led the way, recording $278.9 million and $104.4 million in inflows, respectively, according to data from Farside Investors.
The strong inflow on June 18 reflects continued institutional confidence, with Bitcoin holding steady around the $105,000 mark despite renewed geopolitical tensions, crypto analytics firm Santiment noted in a post on X.
“Despite the initial panic, Bitcoin has remained in the $104K-$105K range, aided by consistent ETF inflows and a lack of follow-through in military actions, mirroring the typical ‘risk-off, then stabilize’ pattern seen in previous geopolitical crises.”
Santiment noted that Bitcoin’s recent price behavior mirrors its response to previous geopolitical crises, such as Russia’s invasion of Ukraine in February 2022 and the Israel-Palestine conflict in October 2023—both of which saw Bitcoin initially drop by around 7% before stabilizing shortly afterward.
On June 18, the only other spot Bitcoin ETF to register inflows was the Bitwise Bitcoin ETF (BITB), which brought in $11.3 million. Meanwhile, ETFs from ARK Invest, Invesco, Franklin Templeton, Valkyrie, VanEck, and WisdomTree recorded no inflows for the day.
Grayscale’s Bitcoin Funds Were the Sole Decliners
The Grayscale Bitcoin Trust ETF (GBTC) saw outflows of $16.4 million, while the firm’s lower-fee offering, the Grayscale Bitcoin Mini Trust, recorded an additional $10.1 million in outflows.
Bitcoin ETF Inflows Surge Amid Market Momentum
After a sluggish start to 2025, inflows into spot Bitcoin ETFs have accelerated sharply, with a total of $11.2 billion pouring in since April 17.
During that period, there have been only eight days of net outflows, while Bitcoin’s price has climbed from below $85,000 to $104,950.
Cumulatively, the 11 U.S.-listed spot Bitcoin ETFs have attracted more than $46.3 billion in inflows. Leading the pack are BlackRock’s iShares Bitcoin Trust (IBIT) with $50.6 billion and Fidelity’s Wise Origin Bitcoin Fund (FBTC) with $11.5 billion.
The overall total also accounts for $23.2 billion in outflows from Grayscale’s Bitcoin Trust (GBTC).
Ether ETFs Hold Their Own in Market Rally
U.S. spot Ether ETFs saw a 19-day streak of inflows before it briefly broke on June 13, but momentum quickly returned with three straight days of new inflows from June 16 to 18—including over $19.1 million on Wednesday.
BlackRock’s iShares Ethereum Trust ETF (ETHA) is leading the group, with total net inflows of $5.28 billion, according to data from Farside Investors.
ETHA has posted inflows on every trading day but two since May 20 and hasn’t seen a single outflow since May 7.
These strong inflows coincide with a shift in tone from the Securities and Exchange Commission’s Crypto Task Force, which has adopted a more collaborative stance toward the industry. The agency recently clarified that protocol-level staking does not constitute a securities transaction—potentially paving the way for Ether ETFs that offer staking features in the future.
