On October 1, Alphabet rose 3.4% in after-hours trading, reaching $353.89 per share with turnover of approximately $727 million, extending momentum from a regular-session gain of over 2.5%. The rally was driven by dual catalysts: the imminent release of its flagship AI model Gemini 4 Pro and the announcement of a collaborative White House AI safety framework.

Leaked benchmarks indicate Gemini 4 Pro outperforms GPT-6 Astra and Claude Fable 5.1 across coding, agentic tasks, and reasoning dimensions. Crucially, its pricing is set at just $2.25 per million input tokens and $11.25 per million output tokens — far below competing flagship models — positioning Google to capture significant market share through aggressive cost advantages. Meanwhile, the White House AI agreement confirmed that Google, alongside NVIDIA, OpenAI, Anthropic, and xAI, will regularly convene to discuss AI safety standards, signaling a regulatory posture of collaboration rather than confrontation and easing fears of heavy-handed intervention.

Additionally, Piper Sandler recently raised its Alphabet price target from $395 to $400, maintaining an Outperform rating, while FactSet consensus stands at $426.66 with an average Buy rating, reflecting broad analyst confidence.
