BlackRock's bitcoin ETF is where institutional money now votes
US spot bitcoin ETFs took in $998.95m on 21 September, their biggest day in eleven months, with BlackRock's IBIT leading at $381.4m as bitcoin briefly cleared $87,000. The week of 21 to 25 September closed at $2.39bn of net inflows, every session positive. IBIT now holds roughly 797,000 BTC and about $67bn in net assets, around three in every five dollars across the category. The nuance worth keeping: that is clients buying ETF shares, not BlackRock buying bitcoin on its own balance sheet, and the flow reversed as recently as mid-September.
WHY IT MATTERS — When the world's largest asset manager becomes the default wrapper, crypto stops being a fringe conversation in your client's investment committee.
