BlackRock's IBIT Tops 784,000 BTC as Two Trackers Give Two Counts

BlackRock's spot bitcoin fund held more coins on Tuesday than the figure now circulating in social posts about it. An Instagram post that reached this desk on 15 September puts the iShares Bitcoin Trust at "well over 765,000 BTC" and "over $60 BILLION," and says Robbie Mitchnick, BlackRock's head of digital assets, told Bloomberg last week that the fund keeps growing because access keeps expanding. The holdings number is stale, and stale on the low side. The quote is real. The timing is not.

Two trackers, two counts

Bitbo's IBIT page put the trust at 784,955.9 BTC, worth about $61.1 billion, as of 11 September. Bitcointreasuries.net put it at 786,654 BTC on 15 September and valued the same pile at $59.5 billion. The coin counts sit roughly 1,700 bitcoin apart. The dollar figures run the other way from the coin counts, which is what a softer bitcoin price does to a growing stack. The two do not reconcile, and neither page shows its working. We could not establish which count matches BlackRock's own reported total at the time of writing.

Both trackers are well above the post's 765,000. On the dollar figure the post is closer. BlackRock's late-August numbers, carried by crypto.news on 26 August, put IBIT's net assets at about $60.65 billion as of 25 August, so "over $60 BILLION" was accurate then. By Tuesday one tracker had the pile back under that line at $59.5 billion, while the other, four days earlier, had it above at $61.1 billion. The coin count is the part of the post that has aged. IBIT's holder list now includes sovereign money, with Abu Dhabi's Mubadala raising its stake to $660 million.

What the $1M minimum actually changed

The access Mitchnick was talking about has a specific mechanism behind it. In July, BlackRock cut the minimum on in-kind conversions from $25 million to $1 million, a 96% reduction. Crypto.news reported the change on 26 August and TFTC returned to it on 6 September. Both give July as the effective month, and neither explains the gap between the change and the coverage. An in-kind swap lets a holder deliver bitcoin and receive fund shares rather than selling for cash. It still runs through an authorized participant. Retail cannot use it.

The volume that mechanism has moved is a late-August figure and has not been updated since. Both outlets put cumulative bitcoin-to-share conversions above $5 billion as of August, against about $3 billion in October 2025. No September tally has appeared.

The quote, and when it was said

"It's going to keep growing because we keep expanding the access. People see things happen in the outside world, whether it's kidnappings, ransom, custody failures, that motivate them to make this switch for all or some of their holdings," Mitchnick said.

TFTC traced that line to a Bloomberg television appearance on 10 August. The coverage carrying it, crypto.news and Forbes among it, ran on 26 August. Neither date is last week. The rest of the post is the author's reading, not BlackRock's: that Wall Street is building easier rails into bitcoin, and that this is bitcoin becoming capital market infrastructure. Mitchnick said access is expanding. He did not say that.

Where the count goes next

Flows have not been one-directional this month. Spot bitcoin funds posted a fourth day of outflows before the Fed meeting, and IBIT's coin count still sits above where the recirculating post puts it. A fund can take redemptions in one week and hold more bitcoin than it did a month earlier. Both are happening. The clean reading arrives when BlackRock's daily disclosure and the public trackers agree on a single number, and this week they did not.
