According to Eric Balchunas, recent weekly fund flows show VOO and IBIT at the top, mirroring last year's trend when 'beta with a side of bitcoin' dominated investment strategies. Notably, IBIT has climbed to 8th place in year-to-date ETF flows with over $6.4 billion in net inflows, a significant rise from being outside the Top 50 earlier this year. This surge, especially post-bitcoin decoupling, signals aggressive bitcoin accumulation within IBIT, highlighting heightened institutional demand and robust ETF trading activity for bitcoin-linked products (source: Eric Balchunas, Twitter, May 5, 2025).
