The first half of 2026 has been the biggest fundraising stretch in the short but explosive history of US spot Bitcoin ETFs. Cumulative net inflows since the vehicles launched in January 2024 now surpassing $58 billion.
The numbers behind the record run
On January 2 alone, US crypto ETFs attracted nearly $670 million in fresh capital. Bitcoin-specific products accounted for $471 million of that haul, with BlackRock’s iShares Bitcoin Trust (IBIT) pulling in approximately $287 million to lead all issuers.
January also delivered one of the most remarkable single-day performances in ETF history. Inflows hit $843.6 million in a single session, the highest figure since October 2025. That day anchored a three-day streak that totaled $1.71 billion.
April turned out to be the real standout month. Bitcoin ETFs posted their strongest monthly inflows of 2026, landing somewhere between $1.97 billion and $2.44 billion — again, the best performance since October 2025.
