BlackRock Files Third Bitcoin ETF, Still Has Just Two Coins

The filing targets about 10 percent loss exposure on each options tranche, before fees³. PBIT runs three overlapping tranches at once. A new one starts every month, as an old one expires. BlackRock's own prospectus language stays blunt about the limits. The filing says the strategy "does not guarantee protection against investment losses"¹. Its floor and cap both stay undefined. That 10 percent figure covers one tranche alone. The fund's overall result still depends on how all three tranches perform together. An investor could still lose the entire stake if the options trades go wrong. BlackRock still must set a fee for PBIT, pending the SEC's review.

A Third Wrapper for an Old Coin

BlackRock's spot bitcoin fund, IBIT, launched in January 2024². IBIT now holds roughly $65 billion. BlackRock added a second fund on June 16, 2026, the iShares Bitcoin Premium Income ETF³. That fund sells covered calls against part of its holdings for monthly income. PBIT, filed Oct. 19, 2026, would make a third design, built around the same asset¹.

Count every coin BlackRock actually sells, and the list stops at two²⁵. Its spot funds cover only bitcoin and ether: IBIT, ETHA and the staked-ether fund ETHB. Rival issuers already run spot funds on XRP and Solana. BlackRock's combined bitcoin and ether fund assets reached $79.6 billion at the end of September⁶. That figure jumped 63 percent from $48.8 billion at the end of June. Appreciation in bitcoin and ether supplied $22.9 billion of that jump, about 74 percent of it. New investor money supplied the other $7.9 billion, the remaining 26 percent. Those funds earned BlackRock $39 million in fees and securities lending revenue during the quarter. The total still sits below the $104 billion peak BlackRock hit in September 2025.

Together the two charts above show where this quarter's growth actually came from⁶.

Mitchnick's Case for Staying Narrow

Robbie Mitchnick runs digital assets for BlackRock⁴. He has made the firm's position plain more than once. Speaking at the Digital Asset Summit in New York in March, he waved off smaller tokens. "The majority of that is nonsense," he said, describing the thousands of coins outside bitcoin and ether. IBIT's own growth gives that view some weight².

Mitchnick's bigger argument points past crypto, toward artificial intelligence as the next source of demand⁴. “AI agents are very unlikely to use, you know, Fedwire and SWIFT. What is crypto? Crypto is computer-native money… AI is computer-native data and intelligence. And so there's a natural symbiosis there,” he said. Read plainly, his bet favors bitcoin and ether over any third or fourth coin.

Geraci's Case Against Standing Still

Nate Geraci leads The ETF Store, and he reads the same facts differently⁵. He called BlackRock's refusal to file for XRP or Solana funds "highly risky." “Still wild to me that BlackRock is refusing to launch spot crypto ETFs other than btc & eth... Not even an index-based crypto ETF. Given massive success of IBIT, ETHA, & ETHB, they're basically making a market call that no other crypto assets have enough value IMO,” he said.

Geraci's point is about business, separate from technology⁵. Bitwise and Fidelity already run funds on XRP or Solana⁹. Together, those funds manage more than $1 billion. A review of SEC records on Aug. 27 found zero BlackRock filing for a spot XRP or Solana fund. Every month BlackRock waits, a competitor keeps that fee revenue instead.

The Buffer's Own Trade-Off

PBIT belongs to a bigger category. Wall Street calls these buffer or defined-outcome funds⁸. That category carries its own warning, apart from the bitcoin-or-altcoin argument. InvestmentNews describes the buffer category as gaining steam among advisors and investors rattled by recent market swings. Buffer funds often charge more than plain index funds. Some run 0.7 percent or higher. A standard index fund can charge as little as 0.05 percent. Nathan Garrison, chief investment officer at World Investment Advisors, has questioned that exchange. “Having someone else cover the first 15 percent of any selloff sounds great, but in exchange for what?” he asked.

That question fits PBIT directly¹³⁸. A PBIT investor gives up part of bitcoin's upside, to pay for a cushion BlackRock's own filing calls uncertain.

What Three Filings and Two Coins Add Up To

Mitchnick's case holds on one condition. Demand for new bitcoin and ether wrappers must keep outrunning demand for every other coin⁴⁶. BlackRock's $79.6 billion in combined fund assets, and its three separate bitcoin products, both support that reading for now².

Geraci's case holds if investors who want XRP or Solana exposure simply buy it elsewhere and stay there⁵. BlackRock's own numbers skip that risk, since the firm sells zero funds in either category.

Mitchnick needs investors to keep choosing new bitcoin and ether products over exposure to any other coin⁴. Geraci needs just one rival to pull meaningful money into XRP or Solana before BlackRock files for either one⁵⁹. Both conditions stay open for now.

Both arguments rest on the same filing¹. PBIT adds a third bitcoin product to a lineup that still covers two coins². Whether that counts as growth, or as standing still, depends on what a reader expects BlackRock's crypto business to become. The next SEC filing, on any coin, will answer that question better than this one did.

By the numbers

• BlackRock's third bitcoin ETF filing arrived Monday, naming the ticker PBIT¹.
• IBIT, BlackRock's original spot bitcoin fund, holds roughly $65 billion².
• BlackRock's combined bitcoin and ether fund assets hit $79.6 billion at the end of September. That is a 63 percent jump from $48.8 billion in June⁶.
• Price gains added $22.9 billion to that total; new investor money added $7.9 billion⁶.
• BlackRock's crypto fund assets remain below the $104 billion peak reached in September 2025⁶.
• PBIT's options tranches target about 10 percent loss exposure before fees, with its floor and cap both left undefined³.
• Bitcoin traded at $81,465 at 01:05 UTC on Oct. 20⁷.
• BlackRock earned $39 million in fees and securities lending revenue from its crypto funds in the third quarter⁶.

What to watch

The SEC still must rule on PBIT. A registration filing can be amended, delayed or withdrawn before any fund trades¹³. Watch whether BlackRock names a launch date or a fee for PBIT in its next amendment. IBIT and the Premium Income ETF each followed that same path before they opened. Watch, too, whether BlackRock's next SEC filing adds a coin beyond bitcoin and ether. Geraci has predicted that move. Mitchnick's public comments point the other way.
