Is the debate over whether AI is ready for high-stakes customer service effectively over?
In its Q4 2025 earnings call, Alphabet dropped a figure that should make every CX leader sit up and take notice: Gemini Enterprise managed over 5 billion customer interactions in the quarter alone.
That represents a 65% year-over-year growth in AI-handled interactions, signaling that the “agentic shift” – where AI agents handle complex, autonomous tasks – has moved from theory to the operational backbone of the world’s largest brands.
For CX leaders, the message is clear: The question is no longer if you should trust AI with your customers, but why you haven’t scaled it yet.
The Scale of the Shift: 5 Billion Reasons to Believe
The sheer volume of interactions reported by Alphabet suggests a tipping point in enterprise trust.
Alongside the 5 billion interactions, Google confirmed it now has 8 million paid Gemini Enterprise seats, with major deployments at brands like Wendy’s, Kroger, and Woolworths.
These aren’t just simple FAQs. Sundar Pichai, Alphabet CEO, noted that we are in an:
“Expansionary moment where AI queries are now 3x longer than traditional search queries. Customers aren’t just asking for hours of operation; they are engaging in complex, multi-turn conversations that require “agentic” reasoning to resolve.”
This shift validates the strategy of early adopters who moved beyond simple chatbots to true AI agents capable of reasoning, context retention, and action.
“Spending Into Strength”: The $175bn Signal
While the interaction numbers are impressive, the financial context behind them provides the security enterprise buyers crave.
Alphabet’s capital expenditure and cash position—often referred to as its “fortress balance sheet”—reached what some market watchers are calling a “$175bn bombshell.” For investors, this massive spending on AI infrastructure can be spooky. But for CX buyers, it is a signal of immense stability.
Thomas Monteiro, Senior Analyst at Investing.com, notes that this spending is exactly what enterprise clients need to see to feel safe building on Google’s stack.
“From the corporate perspective, what we’re seeing play out this earnings season is not exactly an AI reckoning per se, but rather the move from AI as a short-term growth lever to a structural multi-year process.”
Monteiro argues that despite investor hand-wringing over margins, the spending is strategic.
“The investment burden is real… However, despite increased investor scrutiny, this print supports the view that Google is spending into strength and differentiation, not spending to stay relevant.”
For a CX leader choosing a long-term AI partner, this distinction matters. You aren’t buying a tool that might run out of funding in 18 months; you are buying into a “structural multi-year process” backed by one of the largest war chests in history.
From Deflection to Expansion
Perhaps the most interesting signal for contact center leaders is how AI is changing the nature of the interaction.
For years, the goal of automation was “deflection”—keeping people away from expensive human agents. But Google’s data suggests that AI is actually increasing engagement.
With 1 in 6 queries now involving non-text modalities (voice or image) and session times increasing, AI agents are opening up new channels for customer intimacy at scale.
If a customer can have a 3-minute voice conversation with an AI agent to resolve a complex billing issue at 2 AM, that isn’t a “deflected” call. It’s a solved problem and a saved relationship.
The Verdict for 2026
Alphabet’s Q4 earnings have drawn a line in the sand.
With 5 billion interactions and a massive infrastructure commitment backing them up, AI agents have graduated from the innovation lab to the production line.
For CX leaders, the risk profile has flipped. The risk is no longer in deploying AI agents; the risk is in remaining the only competitor in your sector who hasn’t.
