This market resolves YES if, at any point, this website https://gs.statcounter.com/browser-market-share shows Chrome's browser market share for a month at or above 70%, and NO if the website shows Chrome's browser market share for a month at or below 60%. Currently, it's at ~66%, and it's been in the 60s since September 2018 when it first climbed above 60%

If this website goes offline or changes their metrics, I am likely to resolve this market N/A, unless I believe there's another statistic that is exactly the same
