• Ark Invest filed several Bitcoin ETFs on October 14, 2025, under ARK ETF Trust.

• Solmate Infrastructure, backed by Ark, bought Solana after market drop.
• Ark remains the top holder in Solmate, valued near $1 billion as of Q3 2025.

Ark Invest, the investment management firm led by Cathie Wood, has expanded its cryptocurrency ambitions with a new set of Bitcoin exchange-traded fund (ETF) filings. The company submitted several preliminary prospectuses on October 14, 2025, signaling its continued focus on digital assets as institutional demand grows for regulated crypto investment products.

New ETF Filings by Ark Invest

According to PANews, Ark Invest filed applications for multiple Bitcoin ETFs under the ARK ETF Trust. These include the ARK Bitcoin Yield ETF, ARK DIET Bitcoin 1 ETFs (Q1–Q4), and ARK DIET Bitcoin 2 ETFs (Q1–Q4). Each filing was submitted as a preliminary prospectus, marking the early stage of the regulatory review process with the U.S. Securities and Exchange Commission (SEC).

The new ETFs aim to provide investors with structured exposure to Bitcoin’s performance while managing volatility through diversified quarterly series. While details of the underlying strategies were not disclosed, market analysts noted that Ark’s filings indicate continued efforts to expand crypto-linked investment vehicles beyond traditional spot and futures-based funds.

Cathie Wood’s Ongoing Focus on Digital Assets

Cathie Wood has been one of the most vocal advocates for digital assets within the traditional investment community. Ark Invest’s previous involvement in cryptocurrency markets includes partnerships and products linked to Bitcoin and Ethereum. With these latest filings, Ark appears to be broadening its approach to meet varied investor appetites for crypto exposure.

Wood has often emphasized the potential of blockchain technology to reshape financial systems. By introducing new Bitcoin ETFs, Ark Invest continues to align its investment strategy with that vision. The proposed ETFs, if approved, would join a growing list of digital asset products gaining traction among U.S. asset managers following regulatory advancements earlier in the year.

Market Context and Crypto Volatility

The filings come at a time when cryptocurrency markets are experiencing renewed volatility. Last week’s sharp sell-off affected several major digital assets, including Solana, which saw a two-day decline of nearly 22%. The downturn was linked to heightened geopolitical tensions and risk-off sentiment across financial markets.

Despite the turbulence, institutional interest in blockchain-based assets remains strong. Many asset managers are pursuing regulated structures to attract investors seeking safer access to cryptocurrencies. Ark Invest’s latest ETF applications signal continued confidence in the long-term role of Bitcoin within diversified portfolios.

Solmate’s Solana Purchase During Market Pullback

On the same day as the ETF filings, Reuters reported that Solmate Infrastructure, a company backed by Ark Invest, purchased Solana during the market’s recent decline. “We bought the dip,” said Marco Santori, CEO of Solmate Infrastructure. He confirmed that the firm acquired Solana tokens at a 15% discount to market value, though the size of the transaction was not revealed.

Solmate, which was rebranded from Brera Holdings in September, focuses on Solana-based digital infrastructure and treasury management. As of September 30, Ark Invest was the top holder in Solmate, which has a market value of about $1 billion, according to LSEG data. The company’s rebranding followed a $300 million investment from the Solana Foundation, Ark Invest, RockawayX, and UAE-based Pulsar Group.

With the dual developments of new Bitcoin ETF filings and increased activity in Solana-linked ventures, Ark Invest continues to expand its presence across the cryptocurrency sector. The firm’s latest moves reflect its ongoing commitment to building bridges between traditional finance and blockchain innovation.
