TL;DR
Google’s Gemini 3.5 Pro AI model has been delayed multiple times, causing a $425 billion drop in market capitalization. The delay highlights the high stakes of AI development and market expectations.
Google’s Gemini 3.5 Pro AI model has not shipped as scheduled, leading to a $425 billion decline in market capitalization, confirmed by stock market data and reports from Bloomberg.
On July 16, 2026, Bloomberg reported, citing multiple current and former Google employees, that the development of Gemini 3.5 Pro is months behind schedule due to challenges in improving its coding capabilities. Despite initial promises at Google I/O on May 19, 2026, the model remains unreleased, with internal efforts focused on rebuilding the foundation after disappointing training data results.
This delay has had a dramatic market impact: Alphabet’s stock closed down 4.4% the day after Bloomberg’s report, equating to roughly $200 billion in lost market value. Combined with an earlier $225 billion selloff in June following departures of DeepMind researchers, the total market cap loss exceeds $425 billion within a month, even though the company’s Q1 financials remain strong, with $109.9 billion revenue and a 63% increase in Google Cloud revenue to $20 billion.
Third-party sources describe internal issues, including reports of DeepMind discarding a near-ready model and restarting pre-training on a native Gemini 3 foundation, citing reliability problems such as hallucination rates. Google has not officially confirmed these reports, and key specifications like token window size and release dates remain unverified. Multiple deadlines for the model’s launch have passed without delivery, including those set for June and July.
Impacts of Delayed AI Launch on Market and Industry
The delay underscores the high market sensitivity to AI development timelines, where missing deadlines can drastically reduce company valuation. Despite strong financials, the market is now pricing in uncertainty about Google’s ability to lead in AI innovation, which could influence future investments and competitive positioning in the sector.
This situation illustrates how market perceptions can react more to developments and delays than to actual financial performance, emphasizing the importance of timely product launches in the AI arms race.

Recent Developments and Industry Expectations for AI Models
Google announced Gemini 3.5 Pro at I/O on May 19, 2026, with a planned release in June, which was delayed to July. The delay follows reports of internal struggles to improve coding capabilities, a critical area where competitors like OpenAI and Anthropic have gained ground. Meanwhile, other AI models like GPT-5.6 Sol and Grok 4.5 launched publicly in early July, intensifying industry competition.
Market analysts note that Google is now the only major AI lab without a flagship model in production for 2026, raising questions about its leadership position. The delay also coincides with broader industry trends of rapid model deployment and open-weight model releases, which continue to challenge traditional proprietary AI development timelines.
“The model is months behind schedule, primarily over efforts to improve its coding capabilities, and recent training data updates have produced disappointing results.”

Key Questions
Why has Google’s Gemini 3.5 Pro been delayed?
The delay is reportedly due to internal challenges in improving the model’s coding capabilities and reliability issues, including high hallucination rates, though Google has not officially confirmed these reasons.
How much market value has Google lost due to the delay?
Approximately $425 billion in market capitalization has been lost within a month, combining a $200 billion drop after the Bloomberg report and earlier declines linked to DeepMind departures.
What are the broader industry implications of this delay?
The delay highlights the market’s high sensitivity to AI development timelines, with delays risking loss of leadership and investor confidence amid rapid advances by competitors and open-weight models.
Will Google’s delay affect its AI leadership?
Potentially, as competitors like OpenAI and Anthropic continue to release models, and open-weight alternatives challenge proprietary timelines, Google risks falling behind in the AI race if the delay persists.
