Another nearly *$500mil* into iShares Bitcoin ETF…

Starting to get ridiculous.

Geraci observed that BlackRock’s Bitcoin ETF was comfortably in the top five ETFs by inflows this year out of over 4,200 funds. The ETF Store President exclaimed that IBIT’s recent inflows were starting to get ridiculous, adding that the fund had recorded inflows in 30 out of 31 days. IBIT saw only one zero-flow trading day on May 13th.

The fund also gained over $3.86B in inflows over the past two weeks, with a daily average of $430M. Farside data showed that in the past 10 days, IBIT recorded high triple-digit inflows of $409.3M on May 27th, $430.8M on May 23rd, 530.6M on May 21st, $287.5M on May 20th, $305.9M on May 19th, $409.7M on May 15th, and $233.9M on May 14th.

The data also confirmed that the iShares Bitcoin Trust ETF pulled in $877.2M on May 22nd, increasing its total assets to $72.7B. Overall, ETFs attracted an average of $2B for the day.

“IBIT on fire lately, now has $72b in assets, which ranks it 23rd overall, absolutely bonkers for a one year old. The next youngest ETF in the Top 25 is 12yrs old!”

–Eric Balchunas, Bloomberg ETF analyst

Reports on May 22nd also revealed that the iShares 20+ Year Treasury Bond ETF (TLT) attracted $851.8M as investors sought safe havens amid renewed trade tensions, while the iShares Core S&P 500 ETF (IVV) gained $761.5M despite the S&P 500 dropping 0.7%. The Vanguard Total Bond Market ETF (BND) pulled in $403.4M.

Balchunas says IBIT is now among the top 25 largest ETFs

Bloomberg senior ETF analyst Eric Balchunas reacted to BlackRock’s Bitcoin ETF’s performance on May 28, pointing out that the fund’s current AUM of $72B placed it among the top 25 largest ETFs in the world, specifically at the 23rd position. The next youngest ETF within the top 25 was the iShares Core MSCI Emerging Markets ETF (IEMG), which launched back in October 2012.

Balchunas also said on May 19th that IBIT had climbed up to the 6th spot in YTD flows, then on May 21st, he observed that the fund had worked its way into the top 5 list with over $9B in YTD flows. He disclosed that the fund was previously ranked 47th before it went “Full Pac-Man” with a +$6.5B spree. The ETF analyst again claimed on May 23rd that IBIT’s Pac-Man spree was up to about $8B in 5 weeks. 

SosoValue’s data confirmed that IBIT’s consistent inflows began on April 14, when it attracted $36.72M in net investments. Matt Hougan, the CIO at Bitwise, said investors were rushing to Bitcoin ETFs to protect their portfolios against inflation and other macroeconomic factors that plagued traditional fiat currencies.
