Frequently asked questions

The market resolves on May 29, 2026. Resolution is determined by whether Bitcoin spot ETF net inflows occur on May 29, measured against official fund flow data released by providers tracking US-listed Bitcoin ETFs. The outcome hinges on aggregate inflow or outflow figures for that calendar day, with the market settling YES if inflows are positive and NO if they are zero or negative. Traders should monitor fund flow announcements and regulatory filings in the days following May 29 to understand the final result.

Key catalysts include Federal Reserve policy announcements, inflation data, and macroeconomic sentiment shifts that influence institutional Bitcoin demand. Regulatory developments—such as clarity on spot Bitcoin ETF expansion or custody rules—can drive flows significantly. Bitcoin price action itself often correlates with inflow momentum; sharp rallies or crashes typically trigger rebalancing and new capital deployment. Additionally, major corporate or institutional adoption news, geopolitical events, and traditional market volatility can redirect capital into or away from Bitcoin ETFs on any given day, including May 29.
