The strict 24-hour window was dominated by a single event: **NVIDIA's GTC Taipei / Computex 2026 keynote**, delivered by CEO Jensen Huang in Taipei on the morning of June 1, 2026.
The headline was NVIDIA's first serious push into the Windows PC market with the **RTX Spark** "superchip" and a three-year partnership with Microsoft to "reinvent the PC" for the AI-agent era.
The keynote also produced a cluster of secondary announcements (Vera CPU, Nemotron 3 Ultra open-weights model, Cosmos 3 physical-AI model, DGX Station, DLSS 4.5 Ray Reconstruction).
On the software side, **GitHub Copilot's new token-based billing** reportedly went live around June 1 (Microsoft), drawing developer pushback, and **Microsoft Build 2026** was previewed ahead of its June 2–3 keynote. **Honesty note (important):** Genuine in-window news was narrow and heavily concentrated on NVIDIA.
Most of the other monitored companies (OpenAI, Anthropic, Google/DeepMind, Meta, Apple, Amazon, Mistral, Cursor, Replit, Cerebras, Palantir, Oracle, IBM, Tencent, Baidu, Databricks, xAI, Alibaba, Huawei, SenseTime, DeepSeek) had **no announcement confirmably published within the last 24 hours.** Several high-profile stories that surfaced in searches — Anthropic's ~$965B Series H and Claude Opus 4.8 (May 28), Google I/O / Gemini news (May 19–20), OpenAI Rosalind biodefense (May 29), SoftBank's France data-center commitment (May 30), Cognition/Devin (May 28), Mistral Vibe/Physics (May 27–28) — fall **just outside** the window and are deliberately excluded rather than padded in.
They are listed at the end for context only.
Confidence is **HIGH** for the NVIDIA RTX Spark hardware (multiple independent sources plus NVIDIA's own page) and **LOW–MODERATE** for items resting on a single aggregator/secondary source (flagged inline). ---
