Microsoft and OpenAI Rewrite Partnership — Exclusive Deal Ends, AGI Clause Removed

In a joint statement on April 27, Microsoft and OpenAI announced a major rewrite of their partnership:

Non-exclusive license: Microsoft retains access to OpenAI IP through 2032, but now on non-exclusive terms. OpenAI can serve all products across any cloud provider (AWS, Google Cloud, etc.).
Revenue share shift: Microsoft will no longer pay a revenue share to OpenAI. OpenAI will continue paying Microsoft through 2030, subject to a total cap.
AGI clause removed: The famous milestone-based AGI clause has been completely eliminated. Payments continue independent of technology progress. OpenAI may never have to publicly announce if it reaches AGI.
Microsoft remains OpenAI's "primary cloud partner" with products shipping first on Azure unless Microsoft cannot support capabilities.
Microsoft owns roughly 27% of OpenAI's for-profit entity.

The renegotiation resolves legal tension from Amazon's up-to-$50 billion investment in OpenAI (February 2026), which had granted AWS exclusive rights to serve OpenAI's agent-making tool "Frontier." Microsoft had publicly refuted AWS exclusivity at the time, and the Financial Times reported Microsoft contemplated legal action.

China Blocks Meta's $2 Billion Acquisition of AI Startup Manus

China's National Development and Reform Commission (NDRC) formally blocked Meta's $2 billion acquisition of Manus on April 27, directing the companies to withdraw the transaction:

Manus is a Singapore-based AI agent startup founded in China, hailed as the "next DeepSeek." It surpassed $100M ARR within 8 months of launch and raised $75M led by Benchmark.
The blockage is a rare post-completion unwinding and threatens the "Singapore-washing" strategy used by Chinese-founded startups to avoid geopolitical friction.
Parallel scrutiny from Washington: U.S. lawmakers have prohibited American investment in Chinese AI companies.
Meta stock was up slightly following the news.

Industry analyst Ming-Chi Kuo reports OpenAI may be developing an AI-first smartphone with MediaTek, Qualcomm, and Luxshare:

The device would rely on AI agents instead of traditional apps, bypassing Apple and Google app pipeline restrictions.
Hybrid architecture: small on-device models + cloud models. Continuous context awareness.
Specs/suppliers targeted for finalization by year-end 2026 or Q1 2027; mass production 2028.
OpenAI still plans to ship its first hardware product (earbuds) in H2 2026.

📊 Market Moves (Last 48h)

GitHub Copilot Moving to Usage-Based Billing (June 1, 2026)

GitHub announced all Copilot plans will transition to usage-based billing on June 1, 2026:

Premium Request Units (PRUs) replaced by GitHub AI Credits, consumed based on actual token usage at API rates per model.
Base plan pricing unchanged: Pro $10/mo, Pro+ $39/mo, Business $19/user/mo, Enterprise $39/user/mo.
Code completions and Next Edit suggestions remain included (no credit cost).
No more fallback experiences when credits exhausted — users stop instead of falling back to cheaper models.
Copilot code review now consumes both AI Credits and GitHub Actions minutes.
New organizational pooling and admin budget controls.
Promotional credits: Business $30/mo, Enterprise $70/mo (June-August only).
Rationale: Agentic usage becoming default brings significantly higher compute demands.
