Bloomberg senior ETF analyst Eric Balchunas stated on the X platform that the U.S. ETF market is undergoing unprecedented expansion, with 242 ETFs launched in June alone, setting a record for monthly issuances, equivalent to about 11 new products hitting the market each day. By mid-2026, the number of newly launched ETFs has reached 730, and at the current pace, the total for the year could exceed 1450, significantly surpassing last year's record. Balchunas is particularly focused on the aggressive expansion strategy of the emerging issuer Corgi. Data shows that Corgi launched over 100 ETFs in June, currently ranking sixth among ETF issuers. If the current issuance pace continues (the company has approximately 350 ETFs in the registration phase), Corgi could potentially surpass BlackRock by the end of this year, becoming the issuer with the most ETFs in the market. Balchunas noted that BlackRock took over 20 years to build such a large ETF product line, while Corgi may achieve a similar scale in less than a year. However, an increase in quantity does not necessarily mean a corresponding increase in asset size. Currently, some of Corgi's ETFs have attracted a certain amount of capital, but most products are still in the market cultivation stage. The average asset size of its ETF portfolio is about $4 million, while the average size for the entire ETF industry is around $3 billion, indicating that Corgi still faces significant challenges in attracting assets. Corgi's large-scale issuance strategy is described as 'extremely bold,' and its rapid expansion has undoubtedly become one of the most noteworthy phenomena in the current ETF market.
