Alphabet declined to address an investor’s question about Google’s AI partnership with Apple during its fourth-quarter earnings call, opting to ignore the inquiry entirely. The analyst had asked how Alphabet views AI partnerships—specifically the deal expected to power Apple’s Siri with Google’s AI technology.

The silence suggests Alphabet is not yet ready to discuss how the Apple partnership could affect its core business, which is increasingly centered on artificial intelligence. While Google has been open about its ambitions in AI, the revenue implications of large-scale AI integrations remain unclear.

Aside from brief, carefully worded remarks, the Siri deal received little attention during the call, leaving investors with more questions than answers.
