As seen on the 24/7 Wall St. homepage on October 16, 2026.
A 5.74% slide to $93.76 takes roughly $3 billion off the Southeast Asian internet group's $53.2 billion market value in a single session. Moves this size are rare for a name this large, and the $99.47 open is now the level to reclaim.

A single after-hours session wiped roughly $3 billion from Sea's market capitalization, taking the stock from a $99.47 open down to $93.76. A near-6% move of that size marks a real shift in how investors are pricing the stock.
Sea operates across e-commerce, digital financial services, and digital entertainment throughout Southeast Asia, which ties its performance to local economic conditions and broader emerging-market sentiment. The available facts do not specify a catalyst for the after-hours selling.
The $99.47 open is now the immediate line to reclaim for investors. Until the stock closes back above that level in a regular session, the after-hours slide stands as a confirmed breakdown.
Moves of this magnitude in large-cap internet names draw follow-through attention at the next regular open, as traders reassess whether the selling was an overreaction or the start of a sustained repricing. The gap between the open and the after-hours close gives the market a clear reference point in the sessions ahead.
