iShares Bitcoin Trust (IBIT)

The iShares Bitcoin Trust (IBIT) shattered records by amassing $40 billion in AUM within its first year — the fastest growth of any ETF ever, outpacing VOO's launch pace by a factor of three. Managed by BlackRock and launched in January 2024 after SEC approval, it became the quickest ETF to hit $10 billion, achieving this milestone in just 48 trading days. Since inception, IBIT has delivered a 42% gain, eclipsing the 6.8% return of SPY over the same period, though with significantly higher volatility.
