Google reports its fourth-quarter earnings Wednesday after the bell, and Wall Street wants answers about one thing above all else - the blockbuster deal to power Apple's Siri with Gemini AI. The search giant joins the $4 trillion market cap club riding a 70% stock surge over six months, but now investors need proof that its AI investments can translate into revenue. With analysts expecting $111.43 billion in quarterly revenue and earnings of $2.63 per share according to LSEG data, the earnings call marks Alphabet's first chance to detail how its Gemini partnership with Apple's 2.5 billion devices will reshape the AI landscape.
Alphabet is about to find out if its AI spending spree can satisfy Wall Street's appetite for growth. The company reports fourth-quarter earnings Wednesday after markets close, and the scrutiny has never been higher. With the stock up more than 70% over six months and a freshly minted $4 trillion valuation, Google needs to prove it can turn billions in infrastructure investments into actual revenue.
The headline everyone's waiting for? Details on the recently announced partnership with Apple to integrate Gemini AI into Siri. The deal gives Google's AI models access to Apple's staggering 2.5 billion active devices - arguably the most significant distribution win for any AI company to date. Analysts polled by StreetAccount want to know how Google plans to monetize the partnership and what revenue share arrangements look like.
"This is the validation Google needed," one analyst told CNBC. The Apple deal comes as Google races against Microsoft-backed OpenAI and Meta in the increasingly expensive AI infrastructure arms race.
Wall Street consensus puts revenue at $111.43 billion with earnings per share hitting $2.63, according to LSEG data. But the numbers everyone's really watching are Google Cloud revenue - expected at $16.18 billion - and YouTube advertising at $11.84 billion. Both segments have become critical proving grounds for whether Google can maintain its dominance as AI reshapes search and digital advertising.
The fourth quarter saw Google fire on all cylinders with product launches. In November, the company rolled out Gemini 3 to strong reviews, cementing its position as a legitimate challenger to OpenAI's GPT-4. Google also unveiled Ironwood, its seventh-generation tensor processing units designed to compete directly with Nvidia's AI chips and reduce dependency on external hardware.
But the infrastructure demands are staggering. Amin Vahdat, Google's AI infrastructure chief, told employees the company must double its serving capacity every six months just to keep up with demand. "The competition in AI infrastructure is the most critical and also the most expensive part of the AI race," Vahdat said in a November memo obtained by CNBC.
That reality led to Google's acquisition of data center company Intersect for $4.75 billion in cash plus assumed debt in December. The deal signals how seriously Google is taking capacity constraints as AI workloads explode across its cloud and consumer products.
Since the start of 2026, Google's kept the momentum going. The company launched "Personal Intelligence" in January, connecting Gmail, Google Photos, and other apps to deliver personalized responses in the Gemini chatbot. Google also unveiled the Universal Commerce Protocol, positioning itself in AI-powered shopping - a space where Amazon and emerging startups are battling for dominance.
Meanwhile, Google DeepMind brought in the CEO and top engineers from AI voice startup Hume AI through a licensing deal, according to Wired, planning to boost Gemini's voice capabilities. The move comes as voice interfaces become the new battleground for AI assistants - making the Siri partnership even more strategic.
Not everything's smooth sailing. Google filed to appeal a federal judge's ruling that it held an illegal monopoly in internet search. The appeal could delay potential remedies while the legal battle drags on, but the uncertainty hangs over Google's core search business.
One bright spot that'll likely get airtime on the earnings call: Waymo. Alphabet's autonomous driving unit just closed a $16 billion funding round this week, valuing the company at $126 billion. Waymo ended 2025 having completed 15 million trips across five U.S. markets and recently began operations in Miami. The unit also started freeway operations in three cities during Q4 - a technical milestone that demonstrates real progress toward scalable autonomous transportation.
Investors want to know if Google can sustain its 70% stock rally while managing exploding AI infrastructure costs. The company's entry into the $4 trillion club alongside Microsoft, Nvidia, and Apple raises expectations. Every dollar spent on TPU chips, data centers, and AI model training needs to show a path to profitability.
The Apple-Gemini partnership could be that path - or it could be an expensive distribution play that takes years to pay off. Wednesday's earnings call will reveal whether CEO Sundar Pichai and CFO Ruth Porat can articulate how Google turns AI infrastructure dominance into shareholder returns. With cloud, advertising, and now AI assistants all in play, this quarter's results will set the tone for whether Google can maintain its momentum or if the $4 trillion valuation is running ahead of reality.
Google's Q4 earnings represent a pivotal moment for the company and the broader AI race. The Apple partnership gives Gemini unprecedented distribution, but Google needs to show investors it can convert infrastructure spending into sustainable revenue growth. With cloud revenues, YouTube advertising, and Waymo's autonomous driving progress all on the line, Wall Street will be parsing every word from management about how AI investments translate to bottom-line results. The company's 70% stock surge and $4 trillion valuation have set sky-high expectations - now Google has to deliver the numbers and strategy to justify them.
