IBIT absorbs a $1.26B block trade — Bitcoin barely flinches!

At 10:30:34 a.m. ET, a single IBIT print of 29.21 million shares crossed at $43.16, representing roughly $1.26 billion in notional value — about 34.8% of the ETF's entire reported intraday volume of 83.86 million shares. Bitcoin dipped 1% momentarily and recovered almost immediately, with IBIT closing up 0.09% at $42.99 while BTC traded around $75,911.

The trade routed through block desks, market makers, and authorized participants without triggering disorderly repricing — a feat that would have been impossible before spot Bitcoin ETFs existed. Pre-ETF, moving a billion dollars of BTC exposure required either a large OTC arrangement or a sequence of exchange orders that would leave visible price impact across the entire market.

The critical question now is what shows up in the next IBIT flow print.
