Global exchange-traded fund (ETF) net inflows reached a record $1.48 trillion in 2025, marking a 28% increase from the previous year, according to Bloomberg ETF analyst Eric Balchunas. Among the top 15 ETFs, BlackRock's Bitcoin ETF (IBIT) was the only one to post negative returns, with a -6.41% annual performance, attributed to Bitcoin's poor market performance. BlackRock's IBIT ranked sixth in terms of assets under management, holding approximately $248.44 billion. Despite the overall growth in ETF inflows, the negative return of BlackRock's IBIT highlights the challenges faced by Bitcoin-focused funds amid volatile market conditions.
