Anthropic's $30B Series G Caps a Week of Mega Funding Rounds

Anthropic raised $30 billion in a Series G round that values the San Francisco generative AI company at $380 billion post-money — the largest venture deal of 2026 so far and the second-largest of all time, according to Crunchbase data. The round anchors a week in which ten U.S. startups each pulled in $100 million or more.

GIC and Coatue led the Anthropic financing, which the company said was also "co-led" by D.E. Shaw & Co. Ventures, Dragoneer Investment Group, Founders Fund, Iconiq Capital and MGX.

The week's top 10 announced rounds, tracked by Crunchbase for U.S.-based companies, spanned robotics, fusion energy, space tech, healthcare and AI. Combined, the ten deals total more than $36 billion.

What did the rest of the top 10 look like?

• Apptronik, $520 million, humanoid robots. The Austin-based AI robotics company added $520 million as an extension of its $415 million Series A from February 2025, bringing the total round to more than $935 million.
• Inertia Enterprises, $450 million, fusion energy. Bessemer Venture Partners led the Series A for the 2-year-old Livermore, California fusion startup, with Google Ventures, Threshold and other backers joining.
• Axiom Space, $350 million, space tech. Type One Ventures and Qatar Investment Authority led the round for the Houston company building a successor to the International Space Station and developing spacesuits for a moon mission.
• Runway, $315 million, AI. General Atlantic led the Series E, which valued the New York AI research company at $5.3 billion, up from $3.3 billion last April.
• Talkiatry, $210 million, mental health. Perceptive Advisors led the Series D for the New York provider of in-network psychiatry services, bringing its total funding to more than $400 million.
• Solace Health, $130 million, healthcare. IVP led the Series C, valuing the 4-year-old Redwood City patient-advocacy platform at more than $1 billion.
• Garner Health, $118 million, healthcare. Kleiner Perkins led the Series D for the New York company that helps patients find healthcare providers.
• Simile, $100 million, AI simulation. Index Ventures led the Series A for the Palo Alto startup building simulated environments and simulation tools with AI agents.
• Loyal, $100 million, dog longevity. Age1 led the Series C for the 7-year-old San Francisco company developing drugs to extend healthy lifespans in senior dogs.

What does Anthropic's round signal?

The $380 billion post-money valuation cements Anthropic's position at the top of the generative AI funding hierarchy. The round's structure — a single company raising more than the other nine deals combined by a factor of roughly 30 — shows how concentrated capital flows have become at the frontier of AI.

The breadth of the rest of the list matters too. Robotics, fusion, space infrastructure and healthcare all cleared $100 million in the same seven days, per Crunchbase data for the period of Feb. 7–13, suggesting investor appetite for large checks extends well beyond AI.

Runway's valuation jump from $3.3 billion to $5.3 billion in under a year marks one of the sharpest markups of the week, while Loyal's $100 million raise takes the unusual dog-longevity category into late-stage territory — the company says the capital will fund its move from late-stage development to market readiness.

If the pace holds, 2026's megadeal leaderboard — tracked on the Crunchbase Megadeals Board — will keep crowding quickly, and Anthropic may not hold the top slot uncontested for long.
