On October 1, Alphabet rose 3.03% overnight, trading at $354.49/share, with turnover of $46.85 million. The rally was primarily driven by the official launch of its flagship AI model Gemini 4 Argon, alongside aggressive pricing signals for the upcoming Gemini 4 Pro and a supportive White House AI safety framework.

Gemini 4 Argon ranked first or tied for first in 13 out of 18 benchmark tests, excelling in knowledge-intensive tasks and long-context reasoning, with output token limits expanded to the million-level. The model also achieved the lowest hallucination rate among frontier models at 15%. Additionally, leaked benchmarks for the forthcoming Gemini 4 Pro show input pricing at just $2.25 per million tokens, significantly undercutting rival flagship models and positioning Google to capture market share on cost competitiveness.

However, some internal employees have questioned the model's real-world coding performance, particularly in front-end design tasks, despite strong benchmark scores. Google has pushed back on these claims, citing supportive comments from DeepMind leadership. Meanwhile, confirmation that Google and other leading AI firms will participate in regular White House discussions on AI safety standards helped ease regulatory concerns, further lifting sentiment. Options market activity also reflected a bullish bias, with large-scale call spreads and put-selling strategies observed in recent sessions.
