A new exchange-traded fund began trading on Wednesday, offering investors exposure to Bitcoin exclusively during overnight hours when Wall Street is closed. The Nicholas Bitcoin and Treasuries AfterDark ETF made its debut on the New York Stock Exchange, representing one of the more unconventional product structures to emerge from the ETF industry in recent years. Its launch coincided with a notable overnight Bitcoin price move that illustrated the potential appeal of such a fund.
The fund is offered by issuer XFunds and operates through a straightforward daily cycle. During regular trading hours, the portfolio holds cash and U.S. Treasuries to maintain stability. Starting around 4:30 p.m. ET each day, the fund shifts its allocation into Bitcoin futures, options, and other ETFs, then exits those positions before the following morning’s opening bell.
XFunds developed the product in partnership with Tidal Investments, which filed for the ETF in December. At the time of filing, data appeared to show that Bitcoin tended to decline after U.S. markets opened each morning, prompting commentary on social media questioning why American trading hours seemed unfavorable for the asset. Since then, market dynamics have shifted, with statements from President Donald Trump frequently moving markets outside of regular trading hours.
The timing of the ETF’s launch underscored its potential relevance. A ceasefire between the U.S. and Israel was announced on Tuesday evening, and between Tuesday’s market close and Wednesday’s open, Bitcoin climbed 5.8%, rising from $68,600 to $72,600, according to CoinGecko. That kind of overnight movement is precisely what the AfterDark ETF is structured to capture for investors.
In an interview with Decrypt, XFunds CEO David Nicholas acknowledged that investor focus on Bitcoin’s intraday performance during U.S. hours had “died down a little,” but expressed confidence that the ETF would still attract interest. Earlier this year, speculation had circulated about an apparent intraday selling pattern in Bitcoin, with some observers linking it to quantitative trading firm and liquidity provider Jane Street. Multiple experts cautioned against that interpretation, arguing it oversimplified the market mechanics behind spot Bitcoin ETFs.
The AfterDark ETF is the third crypto-related fund XFunds has launched. The firm previously introduced one combining crypto companies with digital assets and another allowing investors to hedge against Bitcoin exposure. Nicholas noted that the latest offering stands out even among the company’s more sector-specific ETFs — which have covered areas such as defense and nuclear energy — describing it as taking “the cake” in terms of complexity, largely due to its unusual settlement mechanics.
Standard stock trades settle within one business day under a system known as T+1. The AfterDark ETF effectively uses a T-1 settlement approach, completing its accounting before the 9:30 a.m. ET opening bell so that overnight price movements are properly reflected in the fund’s value. Nicholas indicated that if the product gains traction, XFunds could explore applying the same after-hours structure to other digital assets, including Ethereum and Solana, though any such expansion would depend on the initial fund’s performance.
