U.S. spot Bitcoin exchange-traded funds have seen 13 consecutive trading days of inflows, bringing in over $2.9 billion.
This is the longest inflow streak since December 2024.
Largest June inflow
The ETFs logged their largest single-day inflow for June—$588.6 million on Tuesday—pushing this week’s total above $1.2 billion.
BlackRock’s IBIT led with $163.7 million on Thursday, followed by Fidelity’s FBTC ($32.9 million) and Bitwise’s BITB ($25.2 million), while other funds like Ark’s ARKB and Invesco’s BTCO saw smaller gains.
Grayscale’s GBT and several minor ETFs reported little to no activity. For a detailed look at ETF flows, see the US bitcoin ETF current and historical holdings.
Institutional interest and market dynamics
The momentum reflects a shift toward institutional investment in Bitcoin. ETF managers increasingly utilize over-the-counter channels to avoid impacting the bitcoin price.
Peter Chung, head of research at Presto Labs, told Decrypt:
“ETF flows are largely driven by two types of investors: Long-only fundamental investors and basis arb traders.”
Chung added that with basis arbitrage less attractive, most ETF flows now come from long-only investors.
On-chain data also shows a decrease in Bitcoin held by short-term holders, indicating that short-term traders have been selling aggressively while institutions accumulate.
