* REX-Osprey launches the first US Ethereum staking ETF (ESK), distributing monthly rewards to shareholders with no fees withheld.
* Bitcoin ETFs saw $149M inflows while Ethereum ETFs faced $79M outflows on September 25th, a notable shift.
REX-Osprey Funds now offers the first exchange-traded fund for Ethereum staking to United States investors. This ETF, with the symbol ESK, acquires Ethereum directly to participate in staking activities.
Its holdings include additional financial instruments that are also engaged in staking. Shareholders receive all staking rewards every month, and the companies involved withhold no fees from these distributions.

He described the ESK fund as a comprehensive tool for obtaining Ethereum exposure along with staking income. King added that this product reflects a continued effort to merge cryptocurrency staking with traditional ETF formats.
“With ESK, we’re giving investors access to Ethereum plus staking rewards in the most broad-based US ETF format,” said Greg King, CEO of REX Financial. “This continues our work of introducing crypto staking through the ETF structure.”
Meanwhile, several large asset managers await rulings from the Securities and Exchange Commission. BlackRock, Fidelity, and Franklin Templeton have each submitted applications for Ethereum funds.
A decision on permitting staking features is still pending. Presently, U.S. spot Ethereum ETFs collectively manage 25 billion dollars in assets. The ETHA fund from BlackRock represents the largest portion of this market.
Risks and Considerations for Investors
The fund documentation highlights several risks. Investors purchase shares in the fund, not Ethereum itself. As a newly formed vehicle, the ETF has no operating history, making future returns unpredictable.
Crypto assets, including ETH, are subject to extreme volatility, regulatory shifts, technological updates, and the risk of market manipulation. Staking carries its own technical and operational challenges, including security and protocol changes. The fund’s performance will depend on how the ETH price and staking market evolve over time.
Investment patterns shifted on September 25. Bitcoin ETFs recorded net inflows of 149 million dollars. Conversely, Ethereum ETFs experienced net outflows totaling 79 million dollars.
Bitcoin (BTC) is trading at $109,047, showing almost no movement in the past 24 hours. Over the past week, the asset has fallen 6.82%, and it is down 2.38% this month. Still, Bitcoin remains up 32% in six months and 72.9% over the year, with a market capitalization of $2.17 trillion and daily trading volume of $71.39 billion.
Markets are bracing for potential volatility as 146,000 Bitcoin options worth $17 billion are expiring today, alongside another $21 billion in Bitcoin and Ethereum options. This large expiration could lead to sudden swings as traders adjust positions.
ETF flows have also been mixed: on September 24, Bitcoin ETFs saw $241 million in inflows, led by BlackRock’s iShares fund, but a day later, they registered $258 million in outflows, showing uncertainty among institutional investors.
Another layer of support for Bitcoin comes from the U.S. government’s Strategic Bitcoin Reserve, announced by President Trump in March 2025, which now holds 200,000 BTC. This reserve continues to fuel debate about Bitcoin’s role in national financial strategy.
Technically, Bitcoin is consolidating below its all-time high of $124,517, with resistance near $112,000-$115,000 and support between $107,000-$108,000. Oscillators and moving averages suggest a neutral trend, as markets await clarity from ETF flows and today’s options expiry.
