AI startup lands $863M, Microsoft in-house model & more (August 29, 2025)

Good morning,

Today’s news blends massive funding bets with strategic AI launches and shifting user data policies. From Microsoft unveiling in-house models to Ambani’s India AI play, the week is closing with heavyweight moves.

Let's dig in👇

🚨 Big Moves in AI

💰 Fusion startup lands $863M

Commonwealth Fusion Systems raised $863M with backing from Nvidia, Google, and Bill Gates to accelerate its fusion energy efforts. The round brings its total funding to nearly $3B as it pushes toward commercializing a fusion power plant. If successful, the company aims to send electricity to the grid in the early 2030s, marking a turning point in clean energy.

🚀 Microsoft launches in-house models

Microsoft AI launched its first in-house models, including MAI-Voice-1 and MAI-1-preview. The voice model can generate a minute of audio in under one second on a single GPU, signaling a big leap in efficiency. This positions Microsoft as a stronger player in the AI race, complementing its ongoing OpenAI partnership with homegrown capabilities.

🔐 Anthropic shifts data policy

Anthropic is changing how it handles user data, giving users until September 28 to opt out before chats are used for AI training. The move brings fresh scrutiny to privacy in AI adoption. Critics argue it pressures users into compliance, while Anthropic insists it’s about advancing transparency and model quality.
