Microsoft (MSFT) share price closed Friday, April 24, at $424.62—firmly within the $420-$430 bin—cementing 100% market-implied probability on Polymarket as the week-of-April-20 resolution completes. This strong trader consensus, backed by real capital, reflects steady trading all week with intraday lows above $415 and closes ranging from $418.07 on April 20 to today's 2.13% gain amid broader market weakness and pre-earnings positioning for Q3 results on April 29 (consensus EPS $4.07). Absent major news catalysts over the past 48 hours, low volatility and historical stability support the lock-in; realistic challenges include after-hours surprises or regulatory filings, though significant barriers remain given resolution proximity.
