BlackRock tightens grip on U.S. spot bitcoin ETF market as crypto manager rankings shift

BlackRock is cementing its top spot in the U.S. spot bitcoin exchange-traded fund market with an outsized share, as institutional money flows into regulated ETFs and concentrates assets among a handful of large managers. About 25 asset managers offer crypto products via ETFs, trusts and funds, but the top five control more than $100 billion. Fee competition is intensifying, and Morgan Stanley is being cited as a wildcard after filing an amended S-1 for a spot bitcoin ETF with a 0.14 percent fee.
