Taiwan Semiconductor is also favored as a cheaper alternative to Intel's foundry turnaround story.
Applied Materials and AMD represent two different approaches to AI semiconductors in 2026. Applied Materials, which makes chip factory equipment, earned nearly $28.4 billion in fiscal 2025 revenue with about 24.7% net margin. AMD signed deals with OpenAI and Meta for 6 gigawatts of GPUs each while also powering PlayStation 5 and Xbox consoles. AMD revenue reached about $34.6 billion, growing 34.3%, though Applied Materials faces risks from China export controls accounting for 30% of its revenue.
Cloudflare launched AI Search as generally available, adding multimodal features including image pixel embedding for visual search and optical character recognition on scanned PDFs. The tool accepts files up to 10 MiB and works with any chat model. Free monthly allotments include 1,000 semantic queries and 1,000 full-text queries, with pricing based on content ingested, data stored, and queries run.
Cohere released Embed 5, a new embedding model family for enterprise search, RAG, and agentic retrieval. It comes in two tiers: Pro for maximum retrieval quality and Fast for lower latency and cost. Fast processes 377.3 documents per second versus 159.7 for Pro. Both tiers share one embedding space, supporting 100+ languages and 128K tokens. Pricing is $0.12 per million text tokens for Pro and $0.08 for Fast.

This move allows OpenAI to better understand users' financial habits and provide more personalized recommendations, though it raises serious concerns about data security and privacy.
The SOXX index tracking semiconductor stocks fell 15% over the past three months, its worst quarter in over a year. Hedge fund manager Michael Burry cited an 1880 story about reasoning before written language to question whether AI language models can truly understand information, warning about declining demand and increasing competition in the chip sector.
Japan announced a $140 billion investment plan to build and upgrade AI-focused data centers, using JERA to lead the effort. A new data center hub will be built in Osaka to serve as a model for other cities and support startups, with the project expected to create thousands of jobs.
California Governor Newsom signed SB 951, requiring employers to disclose when AI or automation causes mass layoffs. Starting January 1, 2027, companies with 75 or more employees laying off 50 or more people in a 30-day period must include a technology displacement statement and details about which jobs were replaced by AI in their WARN Act notices.
Cyber attacks on local governments are increasing due to AI, with attackers using the technology to scan across states and find poorly defended municipalities. Massachusetts CIO Jason Snyder reported the trend at the NASCIO Annual Conference, noting three Massachusetts municipalities were attacked simultaneously. State IT leaders are calling for a whole-of-state security approach.
Crypto cards are fueling AI trade and hidden scams, with venture capitalists investing $10 billion in crypto startups this year while also funding AI companies.
