BlackRock cut its Bitcoin ETF minimum creation basket from $25M to $1M, opening institutional access below mega-block trades

Iris Holm & Cyrus Reed

BlackRock cut the IBIT in-kind creation minimum 96% — from $25 million to $1 million — on the same day Bitcoin ETFs logged $144.6 million in net outflows. The threshold change is real, but analysts argue the binding constraint was never the dollar floor: it was always the Authorized Participant relationship.

BlackRock reduced the minimum in-kind creation threshold for its iShares Bitcoin Trust (IBIT) from $25 million to $1 million — a 96% reduction — as confirmed by Robbie Mitchnick, BlackRock's Head of Digital Assets, on Bloomberg Television's ETF IQ on August 10, 2026.

About this episode

On August 10th, BlackRock's Robbie Mitchnick went live on Bloomberg to announce that IBIT — the world's largest Bitcoin ETF — had cut its in-kind creation minimum from $25 million to $1 million. A 96% reduction. The same day, Bitcoin ETFs as a category saw $144.6 million in net outflows. This episode sits with both of those facts and refuses to let either one win too easily. The tax mechanic at the center of this is real and worth understanding: in-kind conversion lets a long-term Bitcoin holder move into an ETF wrapper without triggering a taxable sale. At $25 million, that door was closed to most. At $1 million, it's theoretically open — but the episode is honest about what "theoretically" costs. The Authorized Participant relationship is still the operational gate. Not every RIA has the right broker-dealer infrastructure. The threshold wasn't the binding constraint. What the episode lands on is a quieter, longer argument: this isn't BlackRock reacting to a crowd outside the door. The crowd isn't there yet. It's BlackRock building the plumbing before the pension fund comptrollers, corporate treasuries, and undecided family offices have made up their minds. The $1 million floor will already be there when they do. That's a different story than the headline — and a more interesting one.

Frequently asked

Why did BlackRock lower the IBIT in-kind creation minimum from $25 million to $1 million?

BlackRock's head of digital assets Robbie Mitchnick announced on Bloomberg ETF IQ that the IBIT in-kind creation minimum dropped from $25 million to $1 million. The practical effect for holders of appreciated Bitcoin is that the lower floor now allows conversion of Bitcoin directly into ETF shares without triggering a taxable sale — a benefit the $25 million floor had previously blocked for most smaller holders.

What happened to Bitcoin ETF flows on the day BlackRock announced the IBIT threshold cut?

Bitcoin ETFs recorded $144.6 million in net outflows on the same day BlackRock announced the IBIT in-kind creation minimum drop from $25 million to $1 million. The simultaneous outflows indicate that the cohort who could use the mechanism immediately was not waiting at the door when the announcement was made.

Is the $1 million IBIT threshold enough for a family office or RIA to convert Bitcoin directly into ETF shares?

The $1 million floor is a necessary but not sufficient condition. Even at $1 million, a family office or RIA cannot transact directly with BlackRock — they still need an Authorized Participant, a licensed broker-dealer intermediary, to execute the in-kind swap. Hosts of the Onpode IBIT episode argued that the AP relationship, not the dollar threshold, is the binding operational constraint for most potential users.

What SEC action made Bitcoin ETF in-kind creation and redemption legally possible?

The SEC's Division of Trading and Markets issued FAQs in May 2025 clarifying that broker-dealers can legally facilitate in-kind creations and redemptions for spot crypto ETPs. IBIT launched in January 2024 as a cash-only product; the regulatory clarification was the structural event that enabled in-kind mechanics — BlackRock's threshold cuts are downstream of that decision.

Is BlackRock the first Bitcoin ETF to offer in-kind creation at a lower minimum?

No. Fidelity and Ark Invest both offered in-kind mechanisms before BlackRock's May 2025 threshold cut. The significance of BlackRock's move is that the world's largest asset manager normalizing the mechanism — and reducing the minimum to $1 million — functions as a credibility signal for large institutional allocators who have not yet committed to spot Bitcoin ETF exposure.

Cyrus Reed: Hey, you see Mitchnick on Bloomberg on the 10th — or did it just slide past you?

Iris Holm: I saw it. Kept waiting for the catch.

Cyrus Reed: Right — because on the surface the headline is just... good news? BlackRock's Robbie Mitchnick goes live on ETF IQ and says the in-kind creation minimum for IBIT just went from twenty-five million dollars to one million. A 96 percent drop. And he actually says the line — I keep replaying it — 'Bitcoiners can do in-kind exchanges of BTC for IBIT for one million minimum now.'

Iris Holm: The framing is worth sitting with. 'Bitcoiners.' Not institutions. Not funds.

Cyrus Reed: Huh — yeah, that's an interesting word choice. But okay, before we get into the framing — I want to make sure the base idea is actually clear, because I had to explain this to a friend and I landed on this: it's like a country club that cut its minimum membership buy-in from twenty-five million to one million. Same access, same mechanism, just — the door opened for people who were never close to the old threshold.

Iris Holm: That tracks. Now — who was actually standing outside?

Cyrus Reed: That's — wait, that's the whole mystery. Because the announcement implies there's this huge waiting crowd. But I'm not sure the crowd was there.

Iris Holm: Then we should figure out who it was.

Cyrus Reed: Okay but wait — the crowd question kind of answers itself when you see what actually happened that day. Because the same day Mitchnick is on Bloomberg, Bitcoin ETFs as a category bleed $144.6 million in net outflows. The same day. That's not a crowd rushing in.

Iris Holm: That's the number. $144.6 million out. The announcement is live, the threshold is cut, and the category moves in the wrong direction.

Cyrus Reed: So — wait, is the market just... ignoring him? Like some portfolio manager in a Denver high-rise has Mitchnick's ETF IQ interview on one monitor and IBIT redemptions stacking up on the other, and those two things are just happening simultaneously?

Iris Holm: That's exactly the scene. And Mitchnick's own words close the loop on why. He said in-kind activity is still a minority of overall IBIT volume. He said it. Usage surged once regulators allowed the mechanism — IBIT launched cash-only in January 2024, remember — but he acknowledged it started from a small base.

Cyrus Reed: So the mechanism exists, it grew, but it's still — what, a rounding error on the actual flow?

Iris Holm: The mechanism isn't the engine. That's the structural fact buried under the announcement. Cutting the threshold from $25 million to $1 million is real — 96% reduction is real — but if the families and RIAs who could theoretically use it still need an Authorized Participant to execute the in-kind swap, the threshold wasn't the binding constraint.

Cyrus Reed: Huh. So the AP relationship is the actual gate. Not the dollar floor.

Iris Holm: The outflows don't lie about that. The market read the announcement and kept moving. That $144.6 million isn't confusion — it's the absence of the demand the headline assumed was waiting.

Cyrus Reed: But wait — the AP gate thing, that's actually where the tax story lives. Because the reason a family office or an RIA cares about in-kind at all is — okay, so imagine someone's been holding Bitcoin since 2019. They're sitting on, I don't know, four million in gains. Cash-based creation means they sell first, they realize the gain, they owe taxes on the whole thing before they ever touch an IBIT share. In-kind sidesteps that entirely — they hand over the Bitcoin directly, no taxable event.

Iris Holm: That mechanic is real. No argument.

Cyrus Reed: Right — but here's where the $25 million floor was actually brutal for that person. Four million in appreciated Bitcoin? Old threshold says: not enough. You're selling. You're paying the gains. The one-million floor changes that math directly.

Iris Holm: Except — who executes that conversion? The RIA can't walk up to BlackRock.

Cyrus Reed: No, that's — yeah, they need an Authorized Participant running the transaction. A broker-dealer intermediary. And the reason that's even legally possible now traces back to the SEC's Division of Trading and Markets, May 2025 — they put out FAQs specifically clarifying broker-dealers can facilitate in-kind creations and redemptions for spot crypto ETPs. That was the actual door opening. This threshold cut is just... widening the doorframe.

Iris Holm: The regulatory clarification was the event. The announcement is downstream of it.

Cyrus Reed: Which is also why Mitchnick's 'Bitcoiners' framing snaps into focus — he's not describing net-new buyers. He's describing people repackaging existing Bitcoin exposure into an ETF wrapper. That's a narrower group than the headline implies. And it doesn't create new Bitcoin demand. It just — moves where the Bitcoin sits.

Iris Holm: The AP relationship is still the operational gate. The family office needs the right broker-dealer. Not every RIA has that infrastructure standing by.

Cyrus Reed: And this is where — wait, no, I think there's actually a bigger signal buried here that doesn't fit the 'access for small desks' story at all. Because if the real targets are pension funds, corporate treasuries, the next wave of allocators that haven't moved yet — the threshold cut starts looking less like a product tweak and more like BlackRock pre-building the plumbing before that cohort arrives.

Iris Holm: That's the reframe that actually holds. BlackRock isn't responding to demand — they're anticipating it. Gold ETF infrastructure was refined over decades before pension funds moved in scale. The custody rails, the creation-redemption plumbing, the AP relationships. All of it existed before the wave. This is that.

Cyrus Reed: Wait — so the $144.6 million outflow day might just be... irrelevant to the real argument?

Iris Holm: Exactly. It tells you today's cohort wasn't waiting. It says nothing about the pension fund comptroller who's watching to see if the architecture is mature enough to touch.

Cyrus Reed: And BlackRock is — okay, so they're the world's largest asset manager. When they signal product confidence by cutting thresholds, that's not a coupon. That's a credibility marker for the allocator who hasn't decided yet.

Iris Holm: Now — Fidelity and Ark Invest already offer in-kind mechanisms. So BlackRock isn't even first. What changes is: the largest name in the room just normalized it. That's a different signal.

Cyrus Reed: But the hallway still exists — that's the thing that bothers me. Custody complexity, compliance overhead, AP intermediation. None of that dissolved at $1 million.

Iris Holm: Right. The threshold is one door. Picture a corporate treasurer at a Fortune 500 company — it's August 2026, she's been watching IBIT since January 2024. The cash-only launch looked clunky. The in-kind mechanics look — actually, no, here's the concrete thing — they look like standard commodity ETF plumbing now. Gold, silver, same rails. The normalization is the signal she's waiting for, not the $1 million number itself.

Cyrus Reed: So she's not moving today. But now she knows the infrastructure will be there when she is ready to move.

Iris Holm: And there's one more detail — unconfirmed, but directionally it fits: BlackRock is reportedly planning to push the floor below $1 million. If that's real, this isn't a one-time cut. It's a trajectory. The plumbing gets laid before the neighborhood exists.

Cyrus Reed: Fiber-optic cable to a neighborhood that doesn't exist yet. That's — wait, that's actually the only frame that makes the August 10th outflows and the threshold cut both true at the same time. BlackRock lays the cable. The pension fund comptroller, the corporate treasury, the family offices who haven't decided — they're the neighborhood. And none of them moved on announcement day because they're not moving on announcement day. They're watching to see if the plumbing looks serious.

Iris Holm: That's the part I'll actually sit with. The 96% cut — from $25 million to $1 million — is real. The $144.6 million out is real. Neither one cancels the other. The threshold will already be there when the next cohort decides the math has changed.

Cyrus Reed: Yeah. And nobody has to rush.
