Bitcoin ETFs add $2.9B in last week of June ending month strong

Spot Bitcoin ETFs added $2.92 billion in net inflows between June 23 and June 30, capping off the strongest eight-day streak since mid-May. After slowing inflows in early June, the market appears to have re-engaged with ETFs as geopolitical uncertainty flared again in the Middle East and broader risk appetite improved.

The bulk of the inflows came on June 24 and June 25, when issuers saw a combined $1.14 billion enter products led by BlackRock’s IBIT, Fidelity’s FBTC, and Ark’s ARKB. ARKB saw an unusual $70.2 million on June 25, its second-largest daily inflow in June, suggesting revived institutional positioning after three weeks of weak flows.

In the last week of June, Bitcoin moved up from $105,415 on June 23 to a closing high of $108,382 on June 29 before retreating slightly to $107,210 on June 30. The price advance was relatively steady, with low volatility and rising support around $107,000.

That stability likely encouraged renewed confidence in ETF allocations, especially following the $1.7 billion weekly inflow reported by CoinShares across global crypto funds. US-based spot ETFs appear to have accounted for most of that figure.

June 27 also stood out with a nearly $500 million haul, as BlackRock and Fidelity saw daily inflows above $150 million. Meanwhile, Grayscale’s GBTC continued to leak assets, but outflows were limited to $8 million or less per day compared to the hundreds of millions seen in previous months.

The diminishing GBTC bleed further supports the narrative that ETF rebalancing may be reaching maturity, with capital now flowing more directly into low-fee issuers rather than migrating from legacy trusts.

According to CoinShares, the inflows also came amid a broader 11-week streak of positive inflows across all digital asset investment products. That broader macro context, relatively calm funding rates, and a subdued derivatives market helped steer attention back to ETFs as the more straightforward proxy for directional bets.

The combination of stable prices and strong flows reinforces the growing role of spot ETFs as a barometer of investor sentiment and macro positioning. With June now closed, July begins with ETFs holding over $48.9 billion in assets.
