Combined US spot Bitcoin ETF assets under management surpass gold ETFs for the first time on January 22, 2025 -- just over one year after the spot Bitcoin ETFs were approved. BlackRock's IBIT alone holds over $60 billion in BTC, making it one of the largest ETFs of any kind. Bitcoin achieves in one year what gold ETFs took two decades to build since the first gold ETF (GLD) launched in 2004. The "digital gold" narrative had moved from metaphor to measurable market reality.
