AI Labs

OpenAI

S

Private (public benefit corporation controlled by the OpenAI Foundation)

OpenAI is the world's most widely used artificial-intelligence company, best known for ChatGPT — which surpassed 900 million weekly active users in early 2026 — and for its frontier GPT-5 model family. GPT-5.5 (April 2026) is the broadly available flagship, and the next-generation GPT-5.6 family — Sol, Terra and Luna — opened to the public on July 9, 2026 after an initial government-gated preview. Beyond consumer chat, OpenAI runs a fast-growing enterprise and developer platform (1M+ business customers) that has pushed annualized revenue past ~$25B, and it is building consumer hardware through its ~$6.5B acquisition of Jony Ive's startup io. Following an October 2025 restructuring, the for-profit OpenAI Group PBC is controlled by the nonprofit OpenAI Foundation, with Microsoft holding roughly 27%. In March 2026 OpenAI closed the largest private fundraise in history — $122B at an $852B valuation — and has since filed confidentially toward a potential record IPO.

Anthropic

S

Private (public benefit corporation; confidentially filed for IPO)

Anthropic is a San Francisco AI-safety and research company, founded in 2021 by former OpenAI researchers led by siblings Dario and Daniela Amodei, that develops the Claude family of large language models. As of mid-2026 its lineup spans Claude Haiku 4.5, Claude Sonnet 5, the flagship Claude Opus 4.8, and its most capable widely released model, Claude Fable 5 (plus the invitation-only Claude Mythos 5). Claude is delivered through the claude.ai apps, the Claude API, enterprise plans, and Claude Code — its agentic coding tool, which alone surpassed a $2.5B run-rate and 2M+ weekly active users. Anthropic differentiates on safety and interpretability research and runs on massive cloud partnerships with Amazon (Project Rainier) and Google (up to $40B in cash and compute). Run-rate revenue reached ~$47B by May 2026; that month it raised a $65B Series H at a $965B valuation — briefly the world's most valuable AI startup — and on June 1, 2026 it filed confidentially for an IPO.

Google DeepMind

S

Alphabet subsidiary (Google's consolidated AI research division; not separately traded)

Google DeepMind is Alphabet's consolidated artificial-intelligence research lab, formed in April 2023 by merging the original DeepMind (founded in London in 2010, acquired by Google in 2014) with Google Brain. Led by Nobel laureate and co-founder Demis Hassabis, it builds the Gemini family of frontier multimodal models — which powers the Gemini app (900M+ monthly active users as of mid-2026), Google Search's AI Mode and AI Overviews, Google Cloud's Vertex AI, and, via a 2026 partnership, Apple's next-generation Siri. Beyond consumer AI, DeepMind pioneered game-playing systems (AlphaGo, AlphaZero) and scientific breakthroughs including AlphaFold — whose protein-structure database has been used by 3M+ researchers and earned Hassabis and John Jumper the 2024 Nobel Prize in Chemistry — plus AlphaGenome, AlphaEvolve, Veo and Genie world models, and Gemini Robotics. Its drug-discovery spinout Isomorphic Labs is preparing first-in-human oncology trials. As of July 2026 DeepMind runs on Google's custom TPUs and is racing to ship Gemini 3.5 Pro after several delays, while Hassabis has become a leading public voice calling for a global frontier-AI standards body.

xAI

A

Public — AI & social-media division of SpaceX (Nasdaq: SPCX); rebranded SpaceXAI in July 2026

xAI is Elon Musk's artificial-intelligence company — founded in March 2023, merged with the X social platform in March 2025, acquired by SpaceX in a $250B all-stock deal on February 2, 2026, and rebranded SpaceXAI on July 6, 2026. It builds the Grok model family, whose latest release, Grok 4.5 (July 9, 2026, co-developed with Cursor), Musk pitches as 'Opus-class but faster and cheaper' at $2/$6 per million tokens; Grok features reached ~117 million monthly active users by March 2026, third in the US behind ChatGPT and Gemini. Its Memphis-area Colossus supercomputer complex — roughly 555,000 Nvidia GPUs expanding toward 2 GW and 1 million GPUs — has become a business in itself, leased to Anthropic ($1.25B/month for all of Colossus 1) and Google ($920M/month from October 2026), though it also drew an April 2026 NAACP lawsuit over gas-turbine emissions in South Memphis. Grok is embedded in X (600M MAU), Tesla vehicles, and the Pentagon's GenAI.mil platform. The combined SpaceX went public on June 12, 2026 in history's largest IPO (~$85.7B raised), and the division's next act — the 6-trillion-parameter Grok 5 — is still training on Colossus 2 after slipping past two target windows.

Mistral AI

A

Private

Mistral AI is Europe's leading frontier AI lab, founded in April 2023 in Paris by CEO Arthur Mensch (ex-Google DeepMind) with chief scientist Guillaume Lample and CTO Timothée Lacroix (both ex-Meta). It champions open-weight models: its December 2025 Mistral 3 generation includes Mistral Large 3, a 675B-parameter sparse mixture-of-experts model released under Apache 2.0, alongside commercial and specialist models (Medium 3.5, Small 4, Magistral reasoning, Codestral/Devstral coding, Voxtral audio, OCR 4 documents and the new Robostral robotics line). Its consumer assistant Le Chat was rebranded 'Vibe' in May 2026 and repositioned as an agentic work-and-code platform. Positioned as Europe's sovereign alternative to US labs, Mistral has deep industrial and government ties — lead Series C investor ASML (~11% stake), Airbus, BMW, Stellantis, CMA CGM (a €100M deal) and a framework agreement with France's Ministry of Armed Forces — and is building its own Nvidia-powered infrastructure through Mistral Compute, whose first 44 MW data center south of Paris came online in mid-2026. Annual recurring revenue passed $400M in early 2026, up roughly 20x year over year, with a $1B+ target by year-end, and in June 2026 the company was reported to be in talks to raise about €3B at a ~€20B valuation.

DeepSeek

A

Private (controlled by founder Liang Wenfeng; preparing a mainland China IPO)

DeepSeek is a Hangzhou-based AI lab, founded in July 2023 by hedge-fund billionaire Liang Wenfeng as a spin-off of his quant fund High-Flyer, that builds frontier open-weight language models at radically low cost. Its January 2025 R1 reasoning model — released under an MIT license and trained for a small fraction of US-lab budgets — briefly made its free chatbot the top US iOS app and triggered a historic market rout in which Nvidia shed roughly $600B in a day. As of mid-2026 its flagship is the DeepSeek-V4 family (V4-Pro at 1.6T total parameters and V4-Flash), open-weight models with 1M-token context reportedly trained on Huawei Ascend chips without Nvidia GPUs. DeepSeek serves ~130M monthly active users, dominates China's chatbot market, and monetizes through an API priced orders of magnitude below US frontier labs. After operating for three years on High-Flyer's money alone, it closed a record ~$7B maiden round at a ~$52B valuation in June 2026 — with most investors taking non-voting stakes that preserve Liang's control — and is preparing a mainland IPO targeted for 2027.

Moonshot AI

A

Private (preparing a Hong Kong IPO)

Moonshot AI is a Beijing-based frontier AI lab, founded in March 2023 by Tsinghua alumnus Yang Zhilin (formerly of Meta AI and Google Brain), best known for its Kimi assistant and the open-weight Kimi K-series models. It built its early reputation on long context — Kimi launched in October 2023 with a then-unmatched 200,000-Chinese-character window, expanded to 2 million in 2024 — before pivoting to open-weight frontier models with Kimi K2 in July 2025. Its November 2025 K2 Thinking model topped agentic benchmarks against closed US rivals, and on July 16, 2026 it released Kimi K3, a ~2.8-trillion-parameter mixture-of-experts model with 1M-token context that is the largest open-weight model ever and claims parity with the best closed frontier models at a fraction of their API price. Backed by Alibaba, Tencent, HongShan and Meituan, Moonshot raised $2B at a $20B valuation in May 2026 (seeking $30B in follow-on talks), quadrupled ARR past $200M, and is unwinding its offshore structure ahead of a planned Hong Kong IPO.

Zhipu AI (Z.ai)

A

Public (HKEX: 2513, listed as 'Knowledge Atlas Technology'; STAR Market A-share listing planned)

Zhipu AI — branded Z.ai internationally — is a Beijing-based frontier AI lab spun out of Tsinghua University's Knowledge Engineering Group in 2019, best known for its open-weight GLM foundation-model family and for becoming the world's first publicly listed LLM company with its January 2026 Hong Kong IPO (HKEX: 2513). Led by CEO Zhang Peng, it ships MIT-licensed frontier models — the current flagship GLM-5.2 (June 2026) is a 744B-parameter mixture-of-experts model with 1M-token context that leads open-source models on several agentic and coding benchmarks — alongside the Z.ai/ChatGLM assistant, API platforms, the AutoGLM agent line and the ZCode coding harness aimed at Anthropic's Claude Code. Added to the US Entity List in January 2025, Zhipu leans into a sovereign-AI strategy, selling government-grade LLM infrastructure across Southeast Asia, the Middle East and Africa. Its stock rose roughly 1,700% in the six months after listing, pushing its market cap past HK$1 trillion (~US$128B), and in July 2026 it raised a further ~$4B placement to fund compute, with an up-to-RMB-15B Shanghai STAR Market listing also planned.
