Polymarket has launched a series of prediction markets betting on which major tech company will become the world's largest by market cap on December 31, 2026. Markets for Microsoft, NVIDIA, Amazon, Saudi Aramco, Apple, Alphabet, Tesla, and SpaceX have collectively attracted over $4.7 million in trading volume, reflecting broader expansion of the platform beyond crypto-native predictions.

Polymarket prediction markets saw a surge in new bets on which company will be the world's largest by market cap at year-end 2026, with over $4 million wagered across markets for NVIDIA, Microsoft, Amazon, Saudi Aramco, Tesla, Alphabet, Apple, and SpaceX. The activity suggests traders see significant uncertainty in tech and energy sector valuations heading into the final half of 2026.

Polymarket prediction markets resolved on SpaceX's IPO, confirming the company closed with a market cap exceeding $1.2 trillion. The resolutions validate Polymarket's role in tracking major corporate milestones.
