Alphabet (GOOGL) Stock: Google Unveils Gemini Spark and New AI Tools at I/O 2026

TLDR

• Google launched Gemini Spark, a personal AI agent that runs 24/7 inside Gmail, Docs, and other Google apps.
• Gemini 3.5 Flash was introduced as Google’s fastest AI model — four times faster than other frontier models.
• Spark will roll out to Google AI Ultra subscribers ($100/month) in the U.S. next week.
• Alphabet stock is up roughly 25% this year and is close to a $5 trillion market valuation.
• Google’s Gemini app now has 900 million users, more than double from 400 million at last year’s I/O.

Google unveiled a wave of AI products at its annual I/O developer conference Tuesday, with Gemini Spark and a faster model at the center of it all.

Gemini Spark is a personal AI agent that runs around the clock. It works inside Google’s apps — Gmail, Docs, Meet — and can complete recurring tasks on your behalf. Think: scanning emails for hidden fee changes, creating Docs from meeting notes, or flagging unusual credit card charges.

Alphabet stock (GOOGL) was up about 0.16% on the day, and is up roughly 25% year-to-date. The company is approaching a $5 trillion market valuation, which would make it only the second company after Nvidia to cross that threshold.

Alphabet Inc., GOOGL

Spark will be available to testers starting Tuesday, with a broader beta rolling out to AI Ultra subscribers in the U.S. next week. AI Ultra is Google’s new $100-per-month subscription tier.

Google also introduced Gemini 3.5 Flash, the company’s fastest model to date. The company says it produces output tokens four times faster than other frontier models, making it particularly well-suited for coding and agentic tasks.

Google’s Search Gets Its Biggest Upgrade in 25 Years

Google said Tuesday that its search engine is getting its biggest overhaul in over 25 years. The updated search box gives users more room to type longer, more detailed queries.

New AI-powered search agents will be able to scan blogs, news sites, and social media and send periodic updates to users — a move aimed at keeping Google at the center of how people find information online.

AI Mode, launched last year, now has over one billion monthly users. Queries in that mode have more than doubled every quarter since launch.

The Gemini app itself has hit 900 million users, up from 400 million at last year’s I/O.

Cloud Growth and New Hardware Bets

Google’s cloud division posted $20 billion in Q1 revenue — a 63% jump from the same quarter in 2025. The company’s cloud backlog now stands at $460 billion in future revenue.

Alphabet and Blackstone are also building a new AI infrastructure company aimed at rivaling firms like CoreWeave, with a target of 500 megawatts of capacity by 2027.

Google plans to sell its custom chips — now in their eighth generation — directly to some customers, in addition to offering access through its cloud platform.

At the conference, Google also showed off new AI smartglasses designed in partnership with Warby Parker and Gentle Monster. The glasses can give directions, translate languages, display texts, and even order from DoorDash. They are expected to ship this fall, with pricing not yet disclosed.

Gemini Omni, a new tool for generating high-quality video from text, audio, and images, was also announced. CEO Sundar Pichai said the focus is on bringing agentic AI capabilities to everyday consumers, not just enterprise users.
