Bitcoin’s late-night rally this week made a strong case for a new kind of ETF that only trades while Wall Street sleeps.
The Nicholas Bitcoin and Treasuries AfterDark ETF, launched Wednesday on the NYSE by issuer XFunds in partnership with Tidal Investments, is built to sidestep the U.S. trading day. During daylight hours the fund holds cash and U.S. Treasuries to dampen volatility; around 4:30 p.m. ET it shifts into Bitcoin exposure—via futures, options and other ETFs—and then exits those positions the next morning before the market opens.
That timing mattered this week. A ceasefire between the U.S. and Israel was announced Tuesday night, and Bitcoin jumped 5.8% between the market close and Wednesday’s open, rising from about $68,600 to $72,600, according to CoinGecko. XFunds’ AfterDark structure is explicitly designed to capture those kinds of overnight moves while keeping daytime holdings stable for investors who prefer not to carry crypto exposure during regular U.S. trading hours.
XFunds CEO David Nicholas told Decrypt that investor focus on Bitcoin’s behavior at the U.S. market open “died down a little,” but he remains optimistic the product can gain traction. The idea for an “after-hours” Bitcoin vehicle dates to a December filing by Tidal, when analyst chatter noted a pattern of intraday weakness in Bitcoin and wondered whether retail investors were effectively blocked from buying into overnight rallies. That theory—and related talk about a single liquidity provider, Jane Street, driving an intraday sell pattern—has been disputed by several market veterans, who cautioned that intraday flows are driven by a complex mix of participants and mechanics.
The AfterDark ETF is the latest in XFunds’ push into crypto-focused products; it’s the firm’s third crypto-related fund. Last June it launched a hybrid ETF combining crypto companies and digital assets, and in the months after it introduced a product aimed at hedging Bitcoin exposure. XFunds also runs similarly structured ETFs applying trading strategies to sectors such as defense and nuclear energy.
A key technical detail: conventional U.S. stock trades settle on a T+1 schedule (one business day). XFunds says AfterDark effectively performs a T‑1-style settlement for the fund’s internal accounting so its overnight allocations are reflected before the New York opening bell at 9:30 a.m. ET. That unusual settlement approach is why Nicholas calls the product particularly “obscure.”
Looking ahead, XFunds says the AfterDark approach could be extended to other digital assets, including Ethereum and Solana, but any expansion will depend on how this initial product performs in the market. For investors who want selective crypto exposure tied to overnight developments, AfterDark is a concrete new option—and this week’s Bitcoin move provided an immediate demonstration of what it’s designed to capture.
