CEO is executing a massive pre-arranged selling plan, with over $220M in sales already completed in the past month. The 10b5-1 plan provides legal cover but the magnitude is unusual for a $39.6B company. Monitor for any acceleration of selling or additional Form 144 filings. The stock's OTC listing and mixed institutional sentiment (4 trims, 2 near-exits) add to the caution.

The filing covers shares acquired via vested stock options and founder shares, and is part of a pre-arranged 10b5-1 trading plan that has already generated over $220 million in sales since mid-July 2026. While the 10b5-1 plan provides some cover, the sheer scale of selling by the CEO is a notable signal.
