The spot Bitcoin ETF market witnessed notable activity on May 15, with BlackRock’s IBIT seeing net inflows of $115 million. The consolidation of Ethereum positions played a significant role in this activity.
The State of Wisconsin Investment Board has sold its entire stake in IBIT, while Avenir Group increased its holdings to $691 million. These actions highlight different institutional strategies.

The inflows have substantial financial implications, possibly affecting Bitcoin’s market dynamics. The activity suggests a return of hedge fund strategies and renewed investor optimism.
The May 15 inflows are seen as a positive signal, contrasting with previous outflows. Market participants monitor further developments closely.
Potential outcomes may affect Bitcoin price and investor sentiment. Historical inflow periods typically correspond with price rallies, indicating significant implications for the broader cryptocurrency ecosystem.
As noted by Eric Balchunas, Senior ETF Analyst at Bloomberg:
“IBIT is taking in so much more than the rest of them. Usually there’s much more parity…My theory, return of the HF [hedge fund] basis trade and some big fish biting after the decoupling and subsequent rally.”
