🧠 Top Story: Jeff Bezos’ AI Startup Nears $38B Valuation — Mega-Rounds Are Back

A major signal just dropped in the startup world:

A new AI startup backed by Jeff Bezos, called Project Prometheus, is reportedly close to raising $10 billion, pushing its valuation to around $38 billion.

What makes this interesting:

• This is one of the largest early-stage AI raises ever
• The company is focused on “physical AI” (real-world systems, not just software)
• It’s aggressively hiring top talent from leading AI labs

Why this matters:

👉 We’re entering a new phase of startup funding:

• fewer deals
• much bigger checks
• extreme concentration at the top

For founders:

👉 The bar is rising — investors are backing category-defining bets, not incremental ideas

2️⃣ Startup funding remains record-breaking (but concentrated)
