Google’s Gemini 3.5 Pro AI model has been delayed multiple times, causing a $425 billion decline in Alphabet’s market value. The delay highlights the impact of absent flagship products on investor confidence.
Google’s Gemini 3.5 Pro AI model has not been released as scheduled, leading to a loss of approximately $425 billion in market capitalization for Alphabet.
This delay, confirmed by multiple reports, underscores the financial impact of product postponements in the high-stakes AI industry, where market confidence hinges on timely launches.
On May 19, 2026, Google announced at I/O that Gemini 3.5 Pro would launch the following month. However, as of July 2026, the model remains unreleased, with internal testing ongoing and no official release date announced.
Bloomberg reported on July 16, citing current and former Google employees, that the project is months behind schedule due to challenges in improving coding capabilities, an area where competitors like OpenAI have gained an advantage. The report also noted disappointing results following a late-June training data update aimed at enhancing coding performance.
Following the Bloomberg report, Alphabet’s stock fell approximately 4.4%, erasing about $200 billion in market value, adding to a prior $225 billion decline in late June linked to departures of DeepMind researchers for competitors. In total, the company’s market cap has shrunk by roughly $425 billion within a month, despite strong financials in Q1 2026, including $109.9 billion in revenue and a 63% increase in Google Cloud revenue to $20 billion.
Third-party sources suggest internal upheaval, with reports of DeepMind abandoning a near-ready model and restarting pre-training on a native Gemini 3 foundation, citing reliability issues such as hallucination rates. Google has not confirmed these reports, and specific technical details, including the model’s specifications and timelines, remain unverified.
Financial Impact of AI Development Delays
The delay of Gemini 3.5 Pro illustrates how postponements of flagship AI models can have profound market consequences, with investor confidence directly tied to product timelines. The $425 billion loss emphasizes that absent or delayed products can significantly diminish a company’s valuation, even when core financials remain strong.
This situation underscores the high stakes in AI development, where market perceptions and competitive positioning are as critical as technical progress. The delay also signals potential challenges in Google’s internal development processes, affecting its ability to maintain leadership in AI innovation.

Recent Developments in AI Product Launches
Initial expectations for Gemini 3.5 Pro were set during Google I/O in May 2026, with a scheduled release in June. However, delays persisted, with multiple deadlines missed, including a widely reported target of July 17 that passed without release. Meanwhile, competitors like OpenAI and other labs launched or announced new models, such as GPT-5.6 Sol and Grok 4.5, in early July.
Market dynamics have shifted as these models became available, while Google’s flagship remains unreleased, despite the company shipping its smaller Gemini 3.5 Flash model, which has proven competitive in some benchmarks. The broader context involves a rapidly evolving AI landscape where timely product launches influence market share and valuation.
