According to Eric Balchunas, IBIT was the leader among all ETFs in daily inflows for the first time, surpassing traditional giants like VOO, as reported on May 23, 2025. This milestone is attributed to heightened trading volume driven by Bitcoin’s all-time high, resulting in approximately $8 billion in IBIT inflows over five weeks. This rapid accumulation highlights growing institutional and retail demand for Bitcoin exposure, reinforcing BTC ETF net flows as a critical metric for crypto market sentiment and liquidity (source: Eric Balchunas, Twitter). Traders should monitor ETF flow trends as they directly impact Bitcoin price dynamics and overall crypto market volatility.
