2026-10-22 (~11:22 AM ET — x.com/elonmusk): the thread's first third-party traffic read — Similarweb figures reposted via X Freeze put Grok.com's September 2026 new-user share at 40.91% of traffic, "the highest percentage of new users visiting its website" among leading GenAI tools (ChatGPT, Gemini, Claude, DeepSeek). The underlying Similarweb post was not opened; single-relay.
2026-10-14 (first record, two posts under an hour apart): (1) OpenAI, EU side (~2:45 PM ET — x.com/OpenAI): "More than half of the AI use among our EU enterprise and business customers now involves these tools," small-business users "grown 8x across the region," plus its Economic Research report "The EU's next chapter in AI is agentic" (openai.com/index) — quantitative over prior general "adoption growing" framing. (2) Perplexity, US side (Arav, ~3:59 PM ET — x.com/AravSrinivas): "America is the market to build for 🇺🇸" — more than 50% of users spending on Automations (recurring agentic tasks) or higher-tier plans are American; "net dollar retention for an American self serve business onboarded on agents is consistently high"; paired with Molly O'Shea's pull-quote (trillion-dollar companies built on US customer bases — "$940B" JPMorgan cited). Watch: the OpenAI report's enterprise list and methodology; Perplexity composition/NDR figures backed by a filing or post; whether the US-vs-EU contrast hardens into positioning; neutral per-platform usage/payment splits.
Background
The thread: regional/segment agentic-adoption economics as reported by the platforms themselves — vendor-self-reported reads on where agents are actually used and paid for, with no independent adoption data in the reporting.
