Google rolls out Gemini 3.6 Flash in GitHub Copilot; Alphabet's Gemini delay and spending worries loom over earnings

Google has begun rolling out its Gemini 3.6 Flash model in GitHub Copilot, designed for enhanced coding and app development. However, Alphabet faces investor scrutiny due to delays in launching its flagship Gemini 3.5 Pro model and concerns over rising data-center expenditures.

Google's Gemini 3.6 Flash, now available in GitHub Copilot, aims to enhance web and app development with improved task-completion rates and token efficiency compared to its predecessor. The rollout is gradual, targeting Copilot Pro, Pro+, Max, Business, and Enterprise users.12

However, Alphabet is grappling with investor concerns following a delay in launching the Gemini 3.5 Pro, a model crucial for competing in the AI coding market. This setback comes as Chinese open-source models increasingly challenge U.S. tech giants, raising fears of overcapacity in AI infrastructure.6

Alphabet's capital expenditure guidance for 2026 has surged to between $180 billion and $190 billion, with plans for equity offerings, including investments from Berkshire Hathaway. Despite a 9% drop in shares since April, the company remains nearly 13% higher for the year, bolstered by a 63% jump in cloud sales.

Analysts predict a 21.3% rise in revenue for the April-June period, driven by cloud business growth, while ad revenue is expected to grow at a slower 13.7%. The cloud sector has benefited from significant deals, including multi-billion-dollar agreements with Meta Platforms and Anthropic. "While Google is missing the boat on AI coding and that's a very real growing concern ... Google's strategy is all about the ecosystem," said Dave Wagner, portfolio manager at Aptus Capital Advisors.

Key Insight
“Gemini 3.6 Flash offers configurable reasoning effort and parallel tool use, billed at provider list pricing. Alphabet raised its 2026 capital expenditure guidance to $180B-$190B in April, and its shares have fallen about 9% since late April despite a 63% jump in cloud sales.”
