Anthropic raises $124M Series A to build reliable, steerable AI systems
Anthropic announced a $124 million Series A round in May 2021, led by Jaan Tallinn with participation from Dustin Moskovitz, Eric Schmidt, and others. The company, founded by Dario and Daniela Amodei, plans to use the funding for computationally-intensive research into large-scale AI systems that are steerable, interpretable, and robust. The round represents Anthropic's founding-era capital raise, establishing its research agenda around AI safety, interpretability, and human feedback integration.
Anthropic Forms New Enterprise AI Services Company with Blackstone, Hellman & Friedman, and Goldman Sachs
Anthropic has announced the formation of a new AI services company co-founded with Blackstone, Hellman & Friedman, and Goldman Sachs, backed by a consortium including General Atlantic, Apollo Global Management, GIC, and Sequoia Capital. The firm will deploy Claude into core operations of mid-sized enterprises—community banks, manufacturers, regional health systems—using embedded Applied AI engineers from Anthropic alongside the new company's own engineering staff. The venture extends Anthropic's existing Claude Partner Network (which includes Accenture, Deloitte, and PwC) by targeting a market segment that lacks in-house resources for frontier AI deployments. This represents a significant structural move by Anthropic to capture enterprise deployment revenue through a dedicated services vehicle rather than purely through API licensing.
Anthropic raises $580M Series B to advance AI safety and interpretability research (2022)
Anthropic raised $580 million in a Series B round in April 2022, led by Sam Bankman-Fried of FTX, to fund large-scale infrastructure for AI safety research. The company, then ~40 people, outlined work on interpretability, steerability, and robustness of large language models. The round is historically notable both for Anthropic's early safety-focused mission and for the involvement of Sam Bankman-Fried, who was later convicted of fraud in the FTX collapse.
Anthropic launches initiative to fund third-party AI safety evaluations
Anthropic announced a funded initiative to source third-party evaluations measuring advanced AI capabilities and safety risks, with priority areas including cybersecurity, CBRN threats, model autonomy, national security risks, social manipulation, and misalignment. The initiative is tied to Anthropic's Responsible Scaling Policy and AI Safety Level (ASL) framework, aiming to address a gap between demand and supply of high-quality safety-relevant evals. Proposals are solicited via an application form, with Anthropic framing the effort as benefiting the broader AI safety ecosystem rather than just internal use.
Anthropic raises Series E at $61.5B post-money valuation
Anthropic has closed a $3.5 billion Series E round at a $61.5 billion post-money valuation, led by Lightspeed Venture Partners with participation from Bessemer, Cisco, Fidelity, General Catalyst, Salesforce Ventures, and others. Proceeds will fund next-generation AI system development, expanded compute capacity, mechanistic interpretability and alignment research, and international expansion. The raise follows the launch of Claude 3.7 Sonnet and Claude Code, with Anthropic citing strong enterprise adoption across customers including Cursor, Zoom, Snowflake, Pfizer, and Amazon's Alexa+.
Anthropic raises $450M Series C led by Spark Capital with Google and Salesforce participation

This is a historically significant funding round for a frontier safety-focused AI lab, though it predates the much larger rounds that followed.
Anthropic Donates $20 Million to Public First Action for AI Policy Advocacy
Anthropic is contributing $20 million to Public First Action, a new bipartisan 501(c)(4) organization focused on AI governance and public education. The donation is intended to support policies including AI model transparency requirements, a federal AI governance framework, export controls on AI chips, and targeted regulation of high-risk AI applications such as bioweapons and cyberattacks. Anthropic frames the move as consistent with its safety mission, noting that effective AI governance would increase scrutiny of frontier AI companies including itself. The organization is led by both Republican and Democratic strategists and will work across party lines.
Anthropic forms $200 million partnership with the Gates Foundation
Anthropic and the Gates Foundation are committing $200 million over four years in grant funding, Claude usage credits, and technical support across global health, life sciences, education, and economic mobility.

The partnership is led by Anthropic's Beneficial Deployments team and includes public goods such as open datasets and benchmarks. This represents a significant scaling of Anthropic's non-commercial AI deployment strategy.
