CFB Talks Digital Assets Episode 58: BlackRock's Matt Kunke on the Launch of ETHB and Staking ETF Mechanics

Around 2 months after its listing, BlackRock's iShares Staked Ethereum Trust ETF (ETHB) is sitting on roughly $600 million in assets - prompting BlackRock to justifiably say ETHB saw a "top-quintile" launch.

CF Benchmarks is the index provider for BlackRock's IBIT, ETHA as well ETHB, so, we're fully stoked to welcome Matt Kunke, CFA — Director and US iShares Digital Assets ETFs Product Strategist — to the CFB Talks Digital Assets podcast!

This conversation gets technical fast – but Matt is at his lucid best throughout.

Listen in for a deep dive on what ETHB unlocks, why it sits alongside BlackRock's original Ether ETF (ETHA) rather than replacing it, and how staking actually works inside an ETP wrapper.

A sample of what's in store:

  • Why BlackRock built ETHB as a separate product instead of converting ETHA — and the reasoning behind giving investors choice
  • The "collateralized bond" mental model for proof-of-stake (PoS), and why correlated slashing — the tail risk everyone names — has never actually happened
  • How ETHB manages its 70%–95% staking range, the entry queue currently sitting at ~50 days, and why the exit queue is the one that really matters
  • The Lido stETH precedent: why sophisticated market actors should keep ETHB-style products at-or-near NAV even in stressed environments
  • Where staking yields are headed post-Pectra, the floor mechanics, and why the glide path is gradual rather than abrupt
  • ETH + staking rewards — how wealth advisors and hedge funds are actually framing the trade
  • Why ETH's wirehouse approval trajectory looks today like IBIT's did roughly nine months ago

Bitcoin Holds the Line After Warsh's Hawkish Speech

Digital assets held onto most of a prior extraordinary rally despite a hawkish Fed policy shock late in the week. Dispersion ran beneath the surface: a rotation toward quality factors, a funding curve cracking at the front end, and an isolated token move within the DACS categories.

Factor Friday - August 28, 2026

Digital assets extended last week's rally, though the pace of gains eased. Leadership broadened down the market cap curve for the first time in weeks, while value-oriented and defensive positioning both lagged the advance.
