The Fork in the Road: Anthropic’s IPO

Hard Fork AI13m 38s

This transcript covers a tech news roundup including Anthropic's confidential IPO filing at a $965 billion valuation, Microsoft's first proprietary reasoning model MAI Thinking One, NVIDIA's Cosmos 3 robotics AI model, Intel's comeback with their Crescent Island AI chip, Strava's new API paywall, and Windborne's AI weather forecasting model beating the ECMWF.

Summary

The transcript opens with Anthropic filing confidentially for an IPO on June 1st, just days after closing a $65 billion Series H at a $965 billion valuation — making them one of the most valuable private companies in the world and surpassing OpenAI's $852 billion valuation. The host notes Anthropic's revenue has exploded from a $9 billion run rate at end of 2024 to $47 billion mid-2025. SpaceX is also planning an IPO on June 12th at a $2 trillion valuation, with an interesting dynamic where Anthropic pays SpaceX over $15 billion annually for data center capacity.

Microsoft unveiled MAI Thinking One, their first fully proprietary reasoning model built without relying on OpenAI or other external AI outputs. Announced at Microsoft Build, the model was built from scratch without model distillation, signaling Microsoft's intent to become an independent AI player rather than remaining dependent on OpenAI. They also launched new image models and a Windows 11 developer mode.

NVIDIA revealed Cosmos 3, a foundational model enabling robots to mentally simulate outcomes before executing actions in real-world environments. The model works by having robots predict probable outcomes for different actions and selecting the optimal one. It is bundled with NVIDIA's Isaac and Omniverse tooling, giving NVIDIA a competitive advantage over rivals like Physical Intelligence and Skild AI.

Intel announced their Crescent Island AI chip, set for limited shipment by end of year. It undercuts NVIDIA and AMD by using cheaper LPDDR5 memory and air cooling instead of expensive HBM and liquid cooling. Targeting inference workloads and price-sensitive markets, the chip may also qualify for sale in China under current export controls — a market largely closed to NVIDIA and AMD. Intel's stock has surged over 200% this year under new CEO Lip Bhutan.

Strava ended their free API tier starting June 2025, citing a 448% spike in developer applications driven by zero-code AI app builders straining infrastructure. Third-party app developers will now pay $11.99/month, while wearable integrations and individual user access remain free. Strava simultaneously launched a direct integration with Anthropic's Claude for personal workout data analysis.

Finally, Windborne Systems released Weather Mesh 6, an AI weather model that claims to outperform the ECMWF — considered the global gold standard. Their competitive edge is a proprietary network of 400 balloons feeding raw sensor data directly to their transformer model, bypassing government data pipelines. The system provides updates every six hours at three-kilometer resolution and counts NOAA, the US Air Force, the US Navy, and commodity traders among its customers.

Key Insights

  • Anthropic's revenue run rate grew from $9 billion to $47 billion in less than half a year, which the host frames as one of the most dramatic revenue explosions in recent tech history.
  • Microsoft explicitly stated that MAI Thinking One was built without model distillation, distancing itself from a cost-cutting strategy that several Chinese AI firms and reportedly even xAI had used by training on outputs from competitor models.
  • Intel's Crescent Island chip may qualify for sale in China under current US export controls — a market the host argues is a significant revenue opportunity that is largely closed to NVIDIA and AMD due to trade tensions.
  • Windborne's Weather Mesh 6 bypasses government atmospheric data pipelines entirely by operating its own 400-balloon sensor network, giving it proprietary data that even Google DeepMind cannot access.
  • Strava attributed its API paywall decision directly to a 448% spike in developer applications driven by zero-code AI app builders, framing it as AI tool proliferation creating infrastructure costs with no corresponding revenue contribution.
