Tech Sector Sees Massive Short Squeeze as Microsoft and Amazon Shares Surge

The recent earnings reports from Microsoft and Amazon have triggered a massive short squeeze in the tech sector. Short sellers had piled into both companies at historic rates, but their bets were severely punished after the firms delivered decisive earnings beats. As a result, shares of Microsoft and Amazon have surged by 27% and 14%, respectively, over the past month.

The heavy short positioning in these two companies was evident even before their earnings reports. However, the combination of cloud growth reacceleration and improved sentiment after the beats forced shorts to cover, leading to a significant mechanical bid that contributed to the outsized moves.

Prediction markets now assign a high probability to Amazon's 2026 capital expenditures exceeding $200 billion, indicating that traders view the recent rally as validation of AI infrastructure demand. Microsoft's post-earnings composite sentiment score sits at 74.43, which is a bullish reading with medium confidence.
