BlackRock Leads $331M Bitcoin ETF Outflow as Altcoin Funds Buck the Trend

US spot Bitcoin ETFs lost another $331.05 million in net outflows on Tuesday, in a session dominated almost entirely by selling pressure on BlackRock's iShares Bitcoin Trust. IBIT alone accounted for $325.58 million of the day's outflow, with the remainder spread across small redemptions at Valkyrie's BRRR and Fidelity's FBTC. No spot Bitcoin ETF recorded net inflows.

Two Sessions, $1 Billion Out

Tuesday's outflow follows Monday's $648 million single-day exit, which was the third-largest daily Bitcoin ETF outflow of 2026 and saw BlackRock IBIT lose $448 million. The two-day total approaches $1 billion in net redemptions and confirms what the broader weekly figures had already shown: institutional sentiment toward US spot Bitcoin exposure has materially shifted within the past two weeks.

Bitcoin ETFs still hold $100.29 billion in net assets across the eleven listed products, and trading volume remained elevated at $1.41 billion on Tuesday. The category is not collapsing. It is being actively repositioned by large allocators who appear to be either taking profits, rotating into other crypto exposures, or de-risking ahead of macro uncertainty.

Ether ETFs are in worse shape on the relative timeline. The category has now logged seven consecutive sessions of net outflows, with Tuesday's $62.30 million loss extending the streak. BlackRock's ETHA again led the declines at $59.37 million, with Fidelity's FETH adding another $3.68 million in outflows. The only positive flow in the Ether category came from Bitwise's ETHW at $756,330, a marginal exception against an otherwise unified pattern of redemptions.

Solana and XRP Are Where Capital Is Actually Going

The more analytically interesting story sits in the altcoin ETF data. Solana funds attracted $3.78 million in net inflows on Tuesday, led by Fidelity's FSOL at $3.22 million and VanEck's VSOL at $560,250. The category has now recorded inflows on every single positive trading day in May, drawing more than $90 million across eight positive sessions with no outflow days at all. Total Solana ETF net assets reached $957.93 million, on track to cross the $1 billion mark by month-end.

XRP ETFs stayed in net inflow territory as well, with $1.48 million flowing in across the category. The entire allocation went to Franklin's XRPZ product, continuing a pattern of selective institutional appetite for XRP exposure. Spot XRP ETFs hit $1.12 billion in total net assets and have brought in roughly $60 million over the past week.

The combined signal is clear. Investors are not abandoning crypto. They are reweighting away from the two largest assets toward alternatives with what they perceive as stronger growth narratives. Solana benefits from the Alpenglow consensus upgrade testing, faster block finality and an active staking yield case. XRP draws institutional interest tied to Ripple's regulatory clarity and the ongoing rollout of XRP-linked payment products.

The Goldman Sachs disclosure earlier this week is the structural detail to watch. The investment bank cut its IBIT holdings to around $690 million and reduced its BlackRock Ether ETF position by roughly 70%. That repositioning happened in Q1 2026, but the disclosure on Monday is one likely contributor to the size and timing of this week's outflow figures. Where the next disclosure cycle lands, particularly across other Wall Street allocators with large IBIT positions, will determine whether this is the start of a sustained outflow phase or a single concentrated repositioning event.
