- BlackRock’s IBIT ETF has become the fastest-growing ETF ever, surpassing US$70 billion in assets under management since launching in early 2024.
- IBIT captured over half of the recent US$817.4 million net inflows across all US Bitcoin ETFs in just two trading days.
- The fund’s dominance stems from BlackRock’s unmatched distribution network, institutional acceptance, and reputation as the “safe choice” amongst competitors.
- Analysts predict an “Alt Coin ETF Summer” with Solana (90 per cent odds) and Litecoin (90 per cent odds) ETFs likely to gain SEC approval soon.
The US-based Bitcoin spot exchange-traded funds (ETFs), listed only at the start of 2024, have seen record-breaking inflows since inception. But one fund has always outperformed the rest: BlackRock’s IBIT ETF.
The fund has, by far, outdone its rivals, and now even surpassed US$70 billion (AU$107.47 billion) as the fastest-growing ETF ever, Bloomberg Senior ETF Analyst Eric Balchunas reported on Crypto Twitter:
IBIT’s share keeps increasing. For example, the past two trading days all US spot Bitcoin ETFs saw US$817.4 million (AU$1.25 billion) in net inflows combined. However, IBIT alone accounts for more than half of these inflows, with US$457.6 million (AU$702.65 million).
IBIT’s domination is thanks to BlackRock’s unmatched distribution reach and institutional acceptance (roughly a third institutional ownership), combined with low fees. The combination of BlackRock’s operational expertise, marketing power and trust as the “safe choice” has made IBIT the standard that other providers are still trying to match.
Nevertheless, all US spot Bitcoin ETFs combined now hold 1.2 million BTC valued at US$132.3 billion (AU$202.9 billion) – or 5.7 per cent of all 21 million of the coin.

Altcoin ETF Summer Coming?
Investor focus could soon shift, as Balchunas believes that several altcoin ETFs could soon be approved:
Get ready for a potential Alt Coin ETF Summer with Solana likely leading the way (as well as some basket products) via [a] note [from James Seyffart] this morning which includes fresh odds for all the spot ETFs.

They have published updated odds for the approval by the US Securities and Exchange Commission (SEC), which means several funds could be green-lit this northern-hemisphere summer.
The analysts believe odds for a Solana (SOL) and a Litecoin (LTC) ETF are 90 per cent, while XRP (XRP) and Dogecoin (DOGE) trail slightly behind with 85 per cent and 80 per cent respectively.
While it’s not clear what demand these funds would receive if approved, BlackRock CEO Larry Fink seems to believe in the sector and the disruptive potential of decentralised finance (DeFi), even potentially threatening the status of the US dollar.
Decentralized finance is an extraordinary innovation. It makes markets faster, cheaper, and more transparent. Yet that same innovation could undermine America’s economic advantage if investors begin seeing Bitcoin as a safer bet than the dollar.
