OpenAI is diversifying its AI compute supply chain with a multi-year, $38 billion agreement with AWS, moving away from its previous exclusive cloud partnership with Microsoft. This strategic shift to a multi-cloud architecture signifies the rising importance and scarcity of high-performance GPUs. AWS will provide OpenAI access to NVIDIA GPUs and CPUs to support training and inference. This move highlights the end of single-cloud strategies and the escalation of AI budgeting to corporate capital planning, emphasizing risk diversification and long-term financial commitments for AI infrastructure.

Fueled by megacap tech stocks, particularly Nvidia, the S&P 500 and Nasdaq reached intraday highs. Nvidia’s valuation surpassed $5 trillion after projecting substantial data center visibility, exceeding Wall Street estimates due to surging AI demand. Potential easing of US-China trade restrictions could further boost Nvidia’s growth. Corning also rebounded, poised to benefit from the increasing demand for fiber optic cables in data centers supporting AI. Investors are awaiting the Federal Reserve’s interest rate decision amidst earnings reports.

Samsung Electronics reported a robust semiconductor recovery in Q3 2025 with operating profit of KRW 12.2 trillion (US$8.6 billion), driven by its Device Solutions division and record-high memory revenue fueled by HBM3E and server SSD sales. This rebound, ending four quarters of decline, stems from strategic shifts, improved market dynamics, and growing AI chip demand. Samsung is mass-producing HBM3E and sampling HBM4, aiming for continued growth in the AI infrastructure market. Foundry business also improved, while System LSI faced challenges.

Nvidia’s CEO Jensen Huang announced at the GTC conference in Washington D.C. that Blackwell GPUs are now in full production in Arizona, marking a shift away from solely Taiwanese manufacturing. This move aligns with demands for domestic chip production, including a request from former President Trump. Nvidia also announced a partnership with Nokia to bolster U.S. 5G/6G infrastructure with Nvidia chips and collaboration to advance U.S. quantum computing capabilities. Export restrictions have impacted the company.

OpenAI urges the U.S. to invest heavily in new energy infrastructure to compete with China in AI. Projects like “Stargate” demand enormous power, straining the U.S. grid. OpenAI advocates adding 100 gigawatts of new energy capacity annually to avoid an “electron gap” and secure leadership in AI. They highlight China’s rapid power expansion as a concern. Increased AI power demands could spur investment in renewable energy and grid infrastructure.

POET Technologies (NASDAQ: POET) secured approximately $150 million in gross proceeds through an oversubscribed registered direct offering of common shares, attracting new institutional investors. Closing is expected around October 28, 2025, pending standard conditions. POET intends to use the net proceeds for acquisitions, R&D, and operational expansion. Pro-forma cash is expected to exceed $300 million post-closing. While the offering provides financial runway, the share issuance may cause dilution.

Anthropic’s plan to deploy up to one million Google Cloud TPUs, valued at tens of billions of dollars, highlights a shift toward diversified AI infrastructure strategies. This expansion, aiming for a gigawatt of capacity by 2026, supports Anthropic’s growing customer base, especially among Fortune 500 companies, signaling a move to production-grade Claude implementations. Anthropic leverages Google’s TPUs, Amazon’s Trainium, and NVIDIA’s GPUs, urging enterprises to avoid infrastructure lock-in and prioritize flexibility for varying AI workloads, while focusing on cost-efficiency and responsible AI deployment considerations.

Applied Digital (APLD) secured a $5 billion, 15-year lease with a U.S. hyperscale data center operator for 200 MW capacity at its Polaris Forge 2 campus, bringing its total leased capacity to 600 MW. Despite the significant deal, APLD’s stock fell over 7%, although it’s still up nearly fourfold year-to-date. The agreement underscores the growing demand for AI infrastructure, with major cloud providers investing heavily. CEO Wes Cummins highlighted Microsoft, Meta, Oracle, Amazon, and Google as potential partners. Applied Digital’s 4 gigawatt active pipeline suggests further growth.
