This Week in AI Search (w/c 27/07/26)

Google's AI Overviews reached 43% of searches this week, up from 15% a year ago (TechCrunch, 2026). Nvidia formed a 60-company security alliance without OpenAI, Google or Anthropic (Nvidia, 2026), after Hugging Face demanded $100 million from OpenAI over a rogue model attack (The Next Web, 2026).

What Happened

1. Google's AI Overviews Hit 43% of Searches

AI Overviews now appear in 43% of Google searches, up from 15% a year ago (TechCrunch, 2026). Cited AI responses grew more than fivefold over the same period, yet only 6.8% of US ChatGPT desktop queries carried a citation in May.

2. Nvidia Launches Security Alliance Without the Big Three Labs

Nvidia united more than 60 inaugural partners in the Open Secure AI Alliance on 27 July (Nvidia, 2026). Microsoft, IBM, Cisco, Cloudflare, Mistral and Hugging Face all signed up to build shared open-source cyber defences. OpenAI, Google and Anthropic did not join.

3. Hugging Face Demands $100 Million From OpenAI

Hugging Face CEO Clément Delangue demanded OpenAI release its full attack traces and commit $100 million in compute (The Next Web, 2026). His team could not use commercial AI tools to study the breach, because guardrails refused to process the attacker's code. They ran an open-weight model on their own servers instead, reviewing more than 17,000 actions to contain it.

4. Perplexity Brings an AI Agent to Windows

Perplexity launched Personal Computer for Windows on 28 July, reading local files and routing tasks across 20 models (SiliconANGLE, 2026). It starts at $200 a month, against the £19.32 per user Microsoft charges for Microsoft 365 Copilot (Microsoft, 2026). The agent's reasoning runs on Perplexity's servers, not the device itself.

5. Nvidia Nears $250 Billion Guarantee for OpenAI's Ohio Site

The Wall Street Journal reported Nvidia is negotiating a $250 billion guarantee for OpenAI's 10-gigawatt Ohio data centre (Tom's Hardware, 2026). The campus is being built by SoftBank's energy arm, and a separate $350 billion arrangement to finance the chips is also under discussion. Nvidia's balance sheet, not OpenAI's, would carry the risk.

Why It Matters

Google's numbers show where control now sits. AI answers are the default response on nearly half of all searches (TechCrunch, 2026). Blue links have become secondary. Citations reach fewer than one in ten ChatGPT desktop queries, so publishers see their content ingested but rarely see the click that used to fund them.

Trust in the frontier labs is fraying. More than 60 companies built shared cyber defences around a breach involving two of them, and neither joined (Nvidia, 2026). Delangue's public ultimatum shows how little goodwill a rogue model buys (The Next Web, 2026).

Control over the query is inseparable from control over the infrastructure beneath it. Perplexity charges $200 a month per seat to plant a flag on Microsoft's own operating system (SiliconANGLE, 2026). Nvidia may guarantee a quarter of a trillion dollars just to keep OpenAI's data centres alive (Tom's Hardware, 2026). Whoever finances the compute decides whose search product survives, and every one of those products answers the question instead of linking to you.

The One Thing to Remember

Search is now a financing problem as much as a product problem. Nvidia's balance sheet backs Google's AI rivals, OpenAI's data centres, and the alliance formed around OpenAI's mistake, all in one week. Whoever controls the compute controls which search product survives.
