Alphabet & Nvidia Invest in OpenAI Co-Founder’s Startup SSI – $32B Valuation

In a major power play that’s sending ripples through the AI world, Alphabet and Nvidia have quietly invested in Safe Superintelligence Inc. (SSI) — a stealth-mode AI startup co-founded by former OpenAI chief scientist Ilya Sutskever. While exact financial terms remain undisclosed, sources familiar with the matter say the startup has already reached a jaw-dropping $32 billion valuation, only months after its launch.

But the big money isn’t just about capital — it’s also about chips. Google is not only investing through Alphabet but has also signed on as SSI’s primary infrastructure partner, granting the startup deep access to its proprietary Tensor Processing Units (TPUs) — a strategic shift that challenges Nvidia’s long-standing GPU dominance.

Let’s break down the key details and what they signal about the future of AI, chips, and cloud infrastructure.

SSI – Alphabet & Nvidia Back SSI: Ilya Sutskever’s AI Startup Lands $32B Valuation and Google TPU Deal

What Is SSI?

Safe Superintelligence Inc. (SSI) is a new AI research lab focused on building foundational models with safety at its core. Co-founded by Ilya Sutskever, one of the minds behind OpenAI’s breakthrough models like GPT-3, SSI is aiming high — both in impact and scale. With limited public information and no consumer product to speak of (yet), the company has already become one of the most closely watched AI startups globally.

Who’s Investing in SSI?

• Alphabet (Google) – Strategic investor and now infrastructure provider through Google Cloud
• Nvidia – The AI chip king, now backing the same startup that’s testing alternatives to its GPUs
• Greenoaks Capital – Led the $32B valuation round
• Other unnamed VCs – Signaling deep investor confidence in Sutskever’s vision

These aren’t just passive investments. The relationship is deeper and more strategic, especially for Google, which has landed SSI as an anchor customer for TPUs — its proprietary AI chips.

Google TPUs vs Nvidia GPUs: The Chip War Heats Up

SSI’s infrastructure preference offers a rare glimpse into a shifting battlefield. While Nvidia dominates over 80% of the AI chip market, SSI has chosen Google’s TPUs as its primary compute engine. Two sources confirmed that SSI is already conducting its AI development primarily on TPUs.

This isn’t just a one-off — Google Cloud’s Darren Mowry told Reuters that deals like this represent a broader pivot to selling TPUs externally, not just using them internally.

🧠 Why TPUs?
Google’s TPUs are designed specifically for AI workloads, offering better efficiency in training and inference for large-scale models. With six generations of development under its belt, Google is now competing head-to-head with Nvidia’s GPUs — and SSI is a high-profile customer to prove it.

Strategic Dual Model: Invest + Supply

Google and Nvidia’s investment in SSI mirrors a growing trend in big tech:

• Google + Anthropic
• Amazon + Anthropic (Trainium chips)
• Microsoft + OpenAI (Azure cloud)
• Nvidia + xAI + OpenAI

This “invest-and-supply” model gives tech giants a two-fold benefit:

1. Early visibility into next-gen AI breakthroughs
2. Massive demand for their cloud and chip infrastructure

SSI is the latest piece in this evolving puzzle.

AI Startups Are Reaching the Stratosphere — Fast

SSI’s valuation shows just how fast the AI valuation curve is accelerating. For context:

• In 2018, SenseTime became the world’s most valuable AI startup at $4.5B
• In 2025, SSI hit $32B — with no public product

This meteoric rise reflects a new reality in AI investing: foundational model research is now the hottest commodity, and capital is flowing in at record levels. Venture investment in AI topped $100 billion in 2024, with generative AI alone jumping from $191M in 2022 to over $25B in 2024.

What Does This Mean for the AI Industry?

• For Startups: SSI’s rise proves that deep technical talent and safety-first approaches can attract billions, even without products.
• For Chipmakers: Nvidia’s lead is being challenged as cloud providers roll out their own chips and woo high-profile clients.
• For Investors: AI research labs are now the new unicorns, often achieving $30B+ valuations faster than any previous tech wave.
• For Enterprises: Expect faster, more efficient AI solutions as cloud-chip partnerships continue to expand.

The Alphabet and Nvidia investments in SSI aren’t just a headline — they mark a seismic shift in AI strategy, infrastructure, and innovation. With Ilya Sutskever at the helm and $32B backing, SSI is already a major player in the race toward safe superintelligence — and the battle over AI’s future just got a whole lot more interesting.
