1. NVIDIA Nemotron 3 Ultra Is Live - Download It Today
NVIDIA's Nemotron 3 Ultra is available as of today on Hugging Face (free weights download), NVIDIA NIM at build.nvidia.com (managed API), OpenRouter, and ModelScope. The model was announced by Jensen Huang at Computex on June 1 and ships as promised. At 550B total parameters and 55B active per token via mixture-of-experts architecture, it delivers over 300 output tokens per second - 3 to 6 times faster than comparable Chinese open models - and scores 48 on the Artificial Analysis Intelligence Index, the highest of any US open-weights model. Chinese model Kimi K2.6 still leads the overall open-weight ranking with a score of 54. Consumer hardware cannot run it. On-premises deployment via HP DGX Station with 775GB unified memory arrives August 2026.

2. SpaceX IPO Roadshow Starts Today at $135 Per Share
SpaceX launched its investor roadshow on June 4 with a fixed price of $135 per share - an unusual move that skips the standard price range process. At $135, SpaceX is valued at $1.77 trillion (assuming EchoStar and Cursor transactions close), making it the seventh-largest US company by market cap and above Tesla. The roadshow runs June 4-11. Pricing is expected June 11 evening. Shares begin trading on Nasdaq under SPCX on June 12. The raise of approximately $75 billion across 555.6 million shares would be the largest IPO in history.
Retail investors get 30% of shares via Robinhood, Fidelity, and Schwab. Indicate interest before June 10 for allocation. Morningstar has published a formal valuation of $780 billion - less than half the IPO price - noting that only Starlink is profitable, xAI is projected to burn $10 billion in 2026, and the 85% voting control Musk retains means public shareholders have no governance influence. ARK Invest projects $2.5 trillion by 2030 based on Starlink subscriber growth and Starship economics.

3. Apple WWDC 2026 Is Five Days Away - Here Is What's Coming
Apple WWDC 2026 opens June 9 at 10AM PT in Cupertino (free stream at apple.com/apple-events). Bloomberg's Mark Gurman - the most reliable Apple leaker - reported in May that Apple and Google have finalized a deal to bring Gemini into Siri as an optional backend for complex queries, joining the existing ChatGPT integration. iOS 20 is expected to be the most significant visual overhaul of the iPhone interface in over a decade; 9to5Mac has reported a unified widget and app layer with live activity integration throughout. Apple Intelligence 2.0 expands Private Cloud Compute with larger on-device models, macOS 17 follows suit, and visionOS 3 brings persistent spatial windows and improved hand tracking for Vision Pro.
Developer betas for all platforms begin June 9 after the keynote. Public betas arrive in July. General availability in September with the iPhone 18 launch. The WWDC 2026 logo is notable: described as "metallic and goth," fading from dark to bright - Apple's visual language almost always foreshadows the design direction of the software being revealed.
