Capital this week ran in two parallel currents. At one end of the stack, the foundation model layer pulled in financing at a scale that now rivals the largest cloud platforms, with Anthropic crossing into near-trillion-dollar valuation territory and Cognition adding ten figures to extend its lead in autonomous software engineering. At the other end, much smaller checks landed on the boring but unavoidable plumbing problems: data pipes for AI agents, AI-native search retrieval, and the power semiconductors that keep AI data centers from melting. The five rounds below are ranked by deal size.

Anthropic

Round: Series H | Sector: AI Foundation Models / Cloud

Anthropic closed a $65 billion Series H at a $965 billion post-money valuation, led by Altimeter Capital, Dragoneer, Greenoaks, and Sequoia Capital, and including $15 billion in previously committed hyperscaler investments such as $5 billion from Amazon. The round nearly triples the company’s $380 billion valuation from February and lifts it past OpenAI as the most valuable AI startup. For enterprise IT, the more relevant signal is the simultaneous announcement of fresh infrastructure deals with Amazon, Google, Broadcom, and SpaceX, which lock in chip, data center, and cloud capacity at a scale that will shape procurement options for every Claude customer.

Cognition AI

Round: Series D | Sector: AI Software Engineering / ITSM

Cognition raised $1 billion in a Series D at a $26 billion valuation, co-led by Lux Capital, General Catalyst, and 8VC, with participation from Founders Fund, Ribbit Capital, Atreides, and Alpha Wave. The funding is earmarked to scale Devin, the company’s autonomous AI software engineering agent, which is already in production at Goldman Sachs, Mercedes-Benz, and several U.S. government agencies. The valuation step-up underscores investor conviction that agent-driven software delivery is now a core enterprise IT category rather than a productivity experiment, and one likely to reset assumptions for both internal engineering economics and external systems integration spend.

Exa Labs

Round: Series C | Sector: AI Search Infrastructure

Exa raised $250 million in a Series C at a $2.2 billion valuation, led by Andreessen Horowitz, to expand its AI-native web search engine and retrieval API. The company already powers search for Cursor, Cognition, HubSpot, OpenRouter, and Monday.com, and serves more than 400,000 developers, putting it among the few independent retrieval providers operating at agent scale. With AI agents projected to outpace human web search volume this year, the round positions Exa squarely on what is becoming a critical, and contested, piece of enterprise AI plumbing.

Daloopa

Round: Series C | Sector: Data Infrastructure for AI

Daloopa secured $47 million in a Series C led by Brighton Park Capital, with Squarepoint Capital, Touring Capital, and Nexus Venture Partners participating, to scale its source-linked financial data platform for AI and agentic workflows. The pitch, increasingly familiar across the lineup, is that AI quality is bounded by the quality of the data agents can reach, and that structured, citation-backed datasets are emerging as a distinct category from generic web retrieval. Coverage now spans more than 5,500 public companies globally, an asset base Daloopa intends to put behind a growing set of buy-side and enterprise AI use cases.

C2i Semiconductors

Round: Series A | Sector: Semiconductors

C2i Semiconductors closed a $16.7 million Series A with TDK Ventures, Peak XV Partners, and a group of semiconductor industry investors, to commercialize a software-defined voltage regulator platform aimed at AI and high-performance computing power delivery. The company projects greater than 96% conversion efficiency against the 94% in incumbent solutions, plus a four-degree-Celsius reduction in processor temperatures, which it estimates at roughly $12 million in annual energy savings inside a 100MW AI data center. With power and cooling now binding constraints on AI capacity buildout, marginal efficiency gains at the regulator level translate directly into compute that can actually be deployed.
