TL;DR
Google’s Gemini 3.5 Pro AI model has been delayed multiple times, leading to a $425 billion decline in Alphabet’s market value. The delay underscores the high stakes in AI race and market expectations.
Google’s Gemini 3.5 Pro AI model has not been released as scheduled,which has raised questions about AI project valuations leading to a market valuation loss of approximately $425 billion for Alphabet within a month. This delay, confirmed by multiple reports, highlights the high stakes and market sensitivity surrounding AI development timelines and product launches, especially in a competitive landscape dominated by OpenAI and Anthropic.
On May 19, 2026, Google announced at I/O that Gemini 3.5 Pro would be available in June. However, as of July 2026, the model remains unreleased, with internal sources and third-party reports indicating it is months behind schedule. Bloomberg reported on July 16 that the delay is primarily due to difficulties in improving the model’s coding capabilities, an area where competitors like OpenAI have gained an advantage. Google declined to comment on the specific timeline, but the market reacted sharply, with Alphabet’s stock dropping 4.4% the day after the report — roughly $200 billion in market cap lost. This follows an earlier $225 billion selloff in late June, attributed to the departure of DeepMind researchers to competitors.
The market’s reaction reflects a broader concern about Google’s position in the AI race, as other major models like GPT-5.6 Sol and Grok 4.5 have launched successfully in July. Despite strong financials in Q1 2026, including $109.9 billion in revenue and a 63% growth in Google Cloud, the absence of a flagship AI model in 2026 has altered investor confidence. Reports suggest that Google may be discarding or rebuilding parts of Gemini 3.5, with unconfirmed claims of reliability issues and halted training processes. The delays have also led to a shift in market dynamics, with smaller, shipped models like Gemini 3.5 Flash performing competitively against unlaunched flagship models, as discussed in industry analyses of AI valuation shifts.
Market Impact of AI Development Delays
This delay demonstrates how market value is highly sensitive to AI product launches, especially when expectations are high. The $425 billion loss underscores the importance of timely innovation in maintaining competitive advantage. It also reflects investor confidence that hinges on the successful deployment of flagship models, which can influence revenue streams and market leadership in AI.

AI Race and Market Expectations in 2026
In 2026, AI development has become a critical battleground among tech giants. Google’s delay contrasts with recent successful launches by competitors like OpenAI and Anthropic, which have introduced new models in July. Historically, Google announced Gemini 3.5 Pro for June, but delays have compounded, with three missed deadlines. The broader context includes a competitive landscape where smaller, shipping models are outperforming unlaunched flagship models, and investor sentiment is shifting based on product timelines rather than financial fundamentals alone.
“Google’s Gemini 3.5 Pro is months behind schedule, primarily over efforts to improve its coding capabilities, with disappointing results from recent training data updates.”

Reports suggest reliability issues and a possible rebuild, but Google has not publicly verified these claims. The impact of these technical challenges on the final product remains uncertain.
Next Steps in Google’s AI Development Timeline
Google is expected to provide an official update on Gemini 3.5 Pro’s status in upcoming quarterly reports or product announcements. Market watchers will be monitoring whether the model launches later this year or if further delays occur. Meanwhile, competitors continue releasing new models, increasing pressure on Google to reassert its leadership in AI.
