BlackRock’s bitcoin ETF outstrips SPDR Portfolio S&P 500 ETF in inflows
As bitcoin recovers above the $103,000 level, BlackRock’s iShares Bitcoin Trust has taken fourth place in 2025 inflows, eclipsing State Street’s SPDR Portfolio S&P 500 ETF.
IBIT has seen $13.7 billion in flows during the year, $4 million more than the SPDR Portfolio S&P 500 ETF, per a Monday X post from Bloomberg ETF analyst Eric Balchunas:
$IBIT has taken over 4th place on the YTD flow leaderboard. Passing $SPLG. What's also wild is IBIT is 5th in 3yr flows (despite only being alive for 1.5yrs). pic.twitter.com/4m2XgdX2o6

SPLG emerged nearly 20 years ago. Meanwhile, IBIT started trading in January 2024.
The year-to-date flows for the world’s largest bitcoin fund trails just three giant funds: Vanguard Total Stock Market ETF, the iShares 0-3 Month Treasury Bond ETF, and the Vanguard S&P 500 ETF.
Michael Saylor, executive chairman of bitcoin treasury firm Strategy, posted, “$IBIT is destined to be first in flows.” Balchunas pushed back, replying, “Possible.. I’ll never say never with IBIT.. altho $VOO is having a moment.. +$82b YTD in June is utterly insane.”
IBIT’s climb in rank comes just weeks after the bitcoin investment vehicle became the fastest ETF in history to reach $70 million in assets under management.
