XFUNDS has launched an exchange-traded fund that rotates between bitcoin exposure overnight and U.S. Treasuries during market hours. The structure introduces a time-based strategy aimed at capturing returns outside traditional trading windows.
The Nicholas Bitcoin and Treasuries AfterDark ETF (NGHT) began trading Wednesday, allocating to bitcoin after U.S. markets close and shifting back into cash and short-term government bonds at the next open. According to XFUNDS, the approach targets periods when bitcoin price activity is less correlated with equities and more influenced by global flows.
Can Overnight Bitcoin Returns Outperform Daytime Risk?
The strategy reflects a growing focus on intraday and overnight market dynamics in crypto trading. Bitcoin trades continuously, but its correlation with U.S. equities tends to increase during regular market hours. By comparison, overnight sessions often capture independent price movements driven by international demand and macro developments outside U.S. trading cycles.
XFUNDS CEO David Nicholas said the fund is designed to “systematically isolate bitcoin’s overnight alpha,” referring to historical patterns where a significant share of returns occurs outside standard trading hours. The fund reduces exposure during the day, when bitcoin has frequently moved in tandem with risk assets such as equities.
The launch comes amid renewed competition in the U.S. bitcoin ETF market. Morgan Stanley’s spot bitcoin ETF (MSBT) also debuted Wednesday with a 0.14% fee, undercutting existing products from major issuers. Bloomberg analyst Eric Balchunas estimates the fund could reach $5 billion in assets under management within its first year.

ETF flows are also showing signs of recovery after months of outflows. According to data, U.S.-listed bitcoin funds recorded approximately $471 million in net inflows on Monday, the largest single-day total in six weeks, led by BlackRock’s iShares Bitcoin Trust and Fidelity’s FBTC.
Market participants are now assessing whether time-based allocation strategies can offer differentiated returns in a crowded ETF field. The next catalyst will be early performance data from NGHT and whether overnight exposure proves consistent across varying market conditions.
