Wood, whose ARK Innovation ETF was the top-performing U.S. equity fund last year, has been a vocal proponent of bitcoin.
Her flagship ARK Innovation fund owns around $820 million worth of shares in cryptocurrency exchange Coinbase Global, making it the fund’s 10th largest holding. Coinbase has fallen 35% since its stock market debut in April.
ARK’s application to the SEC follows recent filings by Fidelity and CBOE Global Markets in March. The SEC is yet to approve a bitcoin ETF.
Bitcoin tumbled in recent days to a two-week low as China’s expanding crackdown on bitcoin mining made investors more uncertain about the future of the leading cryptocurrency. Bitcoin on Monday traded at about $34,450, compared to its April peak of nearly $65,000.
