On September 11, GOOGL rose 3.02% in regular trading. The stock rallied on dual catalysts: reports that Blackstone is dramatically scaling up its Google TPU purchases and a bullish investment bank outlook on cloud revenue potential.

According to reports, Blackstone, the world's largest alternative asset manager, is seeking to procure Google Tensor Processing Units at volumes described as \"multiples\" of the amount originally disclosed when the two firms announced a joint venture in May. Blackstone declined to comment on specific procurement figures. Separately, Oppenheimer issued a report stating that Alphabet's TPU sales opportunity could drive substantial upside to Google Cloud revenue and earnings through 2028, reinforcing the commercial viability of Google's custom AI chips.

The developments helped ease investor concerns that had weighed on the stock earlier this week, when Alphabet fell over 3% after announcing a 13-billion-euro AI infrastructure investment in Finland — its largest single European commitment — which sparked worries about near-term capital expenditure pressures and margin dilution. Additionally, Alphabet announced that its Gemini AI application has officially launched on the Windows platform, broadening its cross-platform reach.
