Cathie Wood’s Ark Invest filed for several new Bitcoin ETFs, including yield-generating and downside-buffered versions.
Cathie Wood’s Ark Invest is doubling down on Bitcoin, filing several ETFs with specialized strategies. On Tuesday, October 14, Ark Invest filed for the Bitcoin Yield ETF and ARK DIET Bitcoin 1 and 2 ETFs with the U.S. Securities and Exchange Commission. The new ETFs will focus on yield and risk mitigation, giving institutions more flexibility when it comes to BTC exposure.
The strategies for Ark Invest’s new ETFs are simple. For one, the ARK Bitcoin Yield ETF targets investors who want cash flows from their BTC holdings. Filings suggest that these ETFs may use options-based strategies such as writing covered calls to generate yield, while maintaining BTC exposure.
At the same time, ARK Defined Income Exposure & Target (DIET) Bitcoin ETFs target risk-averse investors who want downside protection. Namely, DIET 1 ETF offers 50% downside protection, while gain participation is triggered only after BTC rises 5% over the quarter. On the other hand, DIET 2 ETF offers 10% loss protection and shares in gains when Bitcoin is up 0% in the quarter.
Filings come after the SEC moved to streamline crypto ETF approvals, slashing approval time to 75 days or less. Before this move, the SEC’s decision could take more than 240 days, with delays frequently extending this timeline even further.
Moreover, this comes just after the crypto market crash, which wiped out $1 trillion in market value. With institutional investors increasingly worried about potential volatility, Ark Invest’s ETFs with downside protection could help attract more capital to Bitcoin.


BitGo’s move creates further competition in a burgeoning European crypto market that is expected to generate $26 billion revenue this year, according to one estimate. BitGo, a digital asset infrastructure company with more than $100 billion in assets under custody, has received an extension of its license from Germany’s Federal Financial Supervisory Authority (BaFin), enabling it to offer crypto services to European investors. The company said its local subsidiary, BitGo Europe, can now provide custody, staking, transfer, and trading services. Institutional clients will also have access to an over-the-counter (OTC) trading desk and multiple liquidity venues.The extension builds on BitGo’s previous Markets-in-Crypto-Assets (MiCA) license, also issued by BaFIN, and adds trading to the existing custody, transfer and staking services. BitGo acquired its initial MiCA license in May 2025, which allowed it to offer certain services to traditional institutions and crypto native companies in the European Union.Read more
