A pivotal decision by a US federal judge is anticipated, one that could dramatically alter Google's default search arrangement, jeopardizing over $26 billion in annual revenue for Google's parent company, Alphabet. Approximately $20 billion of this sum flows directly to Apple. This financial stake represents nearly a quarter of Alphabet's total operating revenue. While Google stands to lose search traffic and predictability as a result of this ruling, analysts speculate that Apple might face an even more significant financial blow. The precise impact, however, hinges on Apple's ability to swiftly negotiate a new agreement and the breadth of the court's decision.
