Alphabet Inc. (NASDAQ:GOOGL) saw its market capitalization shrink by nearly $200 billion on Thursday, following reports that the launch of its next-generation Gemini AI model has been delayed. The sharp sell-off came as technology stocks broadly declined, but Alphabet's underperformance relative to the Nasdaq Composite suggests investors are imposing a company-specific penalty tied to its artificial intelligence ambitions.
Shares of Google's parent company closed Thursday at $354.46, down 4.44%, and slipped an additional 1.82% in premarket trading ahead of Friday's session. The drop matched 84% of the movement that options had priced in ahead of the company's second-quarter earnings report, scheduled for release on July 22 at 4:30 p.m. EDT. Notably, the single-day loss exceeded Alphabet's projected 2026 capital expenditure range of $180 billion to $190 billion, highlighting what analysts describe as an execution gap rather than mere concerns over a launch date.
According to a Bloomberg report, Google experienced several months of delay with the release of Gemini 3.5 Pro, as engineers continued working to enhance its coding capabilities. Reuters added that an update to the model's training data in late June did not meet internal performance targets. CEO Sundar Pichai had previously set a June deadline for the model's release, telling investors on June 3, "We expect Gemini 3.5 Pro will be coming in June." Google has stated that it is trialing 3.5 Pro with partners and assessing an enhanced Flash model, with a spokesperson emphasizing that the company is "shipping quickly" and maintaining cost efficiency.
Alphabet's 4.44% decline outpaced the Nasdaq Composite's 1.47% drop by nearly three percentage points. The broader sell-off was significant, but the divergence indicates investors are penalizing Alphabet specifically. Among leading AI competitors, Meta Platforms (NASDAQ:META) fell 2.46%, Nvidia (NASDAQ:NVDA) lost 2.40%, and Microsoft (NASDAQ:MSFT) actually gained 1.38%. Alphabet now trades at a trailing P/E of 27.0x, compared to 24.2x for Meta and 23.9x for Microsoft.
The stock had already declined 0.8% over the prior week from July 2 to July 10, and dropped another 0.8% so far this week through Thursday. Despite the recent weakness, Alphabet's commercial foundation remains substantial. Google Cloud set a new first-quarter revenue record at $20 billion, and the company's backlog climbed to $462 billion, driven in part by enterprise demand for AI services.
Next week's earnings call will be a critical test for management. Early consensus forecasts put second-quarter revenue at $116.8 billion, an increase of 21.1% year-over-year. Google Cloud revenue is expected to climb 63.3% to $22.2 billion. Market analyst Fabien Yip noted that investors are monitoring Gemini adoption, API usage, and enterprise partnerships, describing these metrics as "the real test" for market-share growth.
Risks are present on both sides. An extended delay could further raise concerns about Alphabet's expenditure strategy, as the company continues to invest heavily in AI infrastructure. Conversely, a confirmed launch date or improved Cloud performance could help narrow the valuation discount more swiftly. For now, investors are demanding stronger evidence that Gemini's execution will translate directly into revenue, rather than just impressive model benchmarks.
