摩根大通表示，聯發科（MediaTek）的定製AI芯片業務在2028年之後仍有望保持強勁增長。隨着聯發科在谷歌AI加速器項目中的參與度不斷提升，儘管其他芯片設計合作伙伴之間的競爭日益加劇，該業務仍有望持續擴張。摩根大通認爲，市場對於聯發科在谷歌AI芯片供應鏈中地位的擔憂被過度放大，並預計聯發科未來幾代芯片仍將是谷歌的重要合作伙伴。聯發科在連接技術、互連技術以及系統級設計方面的能力，將爲其持續參與相關項目提供支持。摩根大通上調了聯發科2027年和2028年的盈利預期，同時將2027年6月目標價從5300新臺幣上調至5600新臺幣，理由是聯發科定製AI芯片業務的長期增長前景更加樂觀，且該業務有望帶來更強的經營槓桿。
