This market will resolve to "Positive" if total Bitcoin ETF flows on Tuesday, July 28, 2026 are greater than 0, and to "Negative" if they are less than 0. If flows are exactly 0, the market will resolve to 50-50. The resolution source is Farside Investors, specifically the ETF Flow tab available at https://farside.co.uk/btc/ in the "Total" column for the date specified in the title. The total flows will be considered finalized for that day once flows for all ETF providers have been published. If data for any ETF provider remains unpublished by 12 PM ET, 2 days after the date specified in the title, the market will resolve based on all available data published up to that time. If the resolution source becomes permanently unavailable or fails to publish any data by 12 PM ET, 2 days after the specified date, the market will resolve 50-50.

This market resolves around Jul 28, 2026, with the outcome confirmed once the event is verifiable from credible public reporting. Resolution depends on whether measurable net inflows into U.S. spot Bitcoin ETFs occur on that day, as reported by regulatory filings and asset management firms. The result will be based on publicly available data, ensuring transparency and objectivity for all participants on Polymarket.
Key signals include U.S. Treasury or SEC statements about ETF approvals, macroeconomic announcements affecting capital flows, and unexpected trading surges in Bitcoin futures or spot markets. Reports from major asset managers about ETF inflows or outflows, coupled with weekly ETF disclosure filings, could also shift expectations. Any geopolitical or regulatory developments impacting crypto markets may similarly influence this market as Jul 28, 2026 approaches.
