New York, Jan 13, 2026, 16:16 EST — After-hours
- Alphabet Class C shares (GOOG) climbed roughly 1.1% in after-hours trading, building on gains sparked by the Apple-Google AI partnership
- Google’s Gemini models are now powering a revamped Siri, bringing a major player into the AI race
- Investors are eyeing Alphabet’s Feb. 4 earnings for signals on ad demand, cloud growth, and AI investments
Alphabet Inc’s Class C shares (GOOG) jumped roughly 1.1% in after-hours action Tuesday, hitting $336.38 following a $332.73 close.
The late surge followed news that Apple plans to integrate Google’s Gemini models into a revamped Siri and other AI features later this year under a multi-year deal. This marks a win for Alphabet as tech giants race to secure distribution and paying users for generative AI tools. “Apple’s decision to use Google’s Gemini models for Siri shifts OpenAI into a more supporting role,” Parth Talsania, CEO of Equisights Research, told Reuters. 1
Why it matters now: Alphabet’s AI momentum is back in focus after the company briefly hit a $4 trillion market cap on Monday. Investors are hunting for signs that AI-driven features can boost revenue without ballooning costs. “Of the Magnificent 7 stocks, it’s the one name that has surprised us all over the last 12 months,” said Phil Blancato, CEO of Ladenburg Thalmann Asset Management. 2
Google and Apple announced that the next generation of Apple Foundation Models will build on Google’s Gemini models and cloud infrastructure. This collaboration aims to deliver a more personalized Siri experience slated for release later this year. Financial details were not shared. 3
The AI drive is drawing new legal and political attention over Google’s use of content and its bundling of features in Search. This week, Google moved to dismiss a lawsuit from Penske Media, which claims the tech giant’s AI-generated summaries in search results have hurt publishers’ traffic. 4
Tuesday saw U.S. stocks slip, with the S&P 500 falling 0.2% and the Nasdaq edging down 0.1%. Investors digested inflation figures alongside pressure on financial shares, sparked by discussions around a potential credit-card rate cap. 5
Alphabet bulls see the Apple deal as a high-profile win that’s tangible, even if the financial impact isn’t clear yet. Traders want to spot whether this partnership boosts Gemini usage and drives more enterprise demand to Google Cloud—not just chatter among consumers.
That setup works both ways. As expectations climb, even a slight misstep in ad pricing, cloud growth, or cost control could weigh on a stock that’s already surged on AI hype.
Alphabet is set to release its fourth-quarter and full-year 2025 earnings on February 4, with a conference call scheduled for 4:30 p.m. Eastern. This will be the next major event for GOOG following this week’s deal news. 6
