During a week headlined by a key approval for US spot ether ETFs, investor capital poured into America’s bitcoin funds. 

Nearly $1.1 billion collectively entered the 11 US spot bitcoin ETFs, according to Farside Investors data. 

It marked the third straight week of net inflows for the fund category after four consecutive weeks of outflows. 

Last week’s flows marked the highest weekly bitcoin ETF inflow total since the segment saw more than $2.5 billion from March 11 to March 15. The latest total narrowly eclipsed the $948 million of inflows reeled in by the funds between May 13 and May 17.

BlackRock’s iShares Bitcoin Trust (IBIT) led the way with $720 million of net inflows, the data indicates. 

IBIT is on the cusp of surpassing the category leader in assets, the Grayscale Bitcoin Trust ETF (GBTC). As of Friday, IBIT and GBTC managed about $19.6 billion and $20 billion, respectively. 

Grayscale has seen more than $17.6 billion of net inflows since converting to an ETF in January — though those have abated in recent weeks.

David LaValle, the firm’s head of ETFs, said during an event last month that the company “anticipated” the initial wave of outflows given the different types of GBTC holders. 

“We had a number of institutional traders that were taking on positions when the product was trading at a discount to its net asset value,” LaValle noted at the time. “[The conversion] gave the opportunity for those investors to unwind those positions.”

Grayscale is also seeking to launch a cheaper version of GBTC.

James Butterfill, head of research at CoinShares, wrote in a Tuesday report that the inflows into bitcoin ETFs are likely partially due to investors interpreting the Federal Open Market Committee’s minutes and recent macro data as “mildly dovish.”

During a week in which the Securities and Exchange Commission approved 19b-4 proposals for a range of spot ether ETFs, ether-related products in other countries saw $36 million worth of inflows. 

Overall, year-to-date net inflows into digital asset investment products so far total a record-high $14.9 billion, CoinShares data shows.

Innovations on Aptos’ technical design through Raptr, Shardines, and Zaptos approach near-optimal latency and throughput by unlocking 100% utilization of network resources, with the capacity to settle 260k transactions per second with latencies less than 800ms. The original Move language was revamped with the launch of Move 2, supporting more expressivity in smart contract logic and a scalable ability to interact with high volume datasets. The ecosystem has benefitted from strong asset inflows, now hosting over $1.3B in stablecoins, $450M in bridged BTC, and $530M in RWAs. Activity in the Aptos ecosystem has grown notably over the past year, with monthly application revenue reaching ~$835k and monthly DEX volumes growing to over $5B, both at new all time highs.
