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).

According to Eric Balchunas, the VOO ETF has reached an extraordinary milestone, tying for the second-best calendar year ever for inflows, amassing over $50 billion by April. This is particularly remarkable given the S&P 500's 10% decline and high market volatility. Notably, VOO's inflows are more than three times that of any other ETF, highlighting its strong investor confidence despite the turbulent market conditions.
