PAC Establishment, $400M Acquisition, Extraordinary Secondary Market Demand, and OpenClaw Billing Changes—Reading Anthropic Through Four News Stories

Over the 48 hours of April 3–4, 2026, four distinct news stories regarding Anthropic converged. The escalation of political activity, an acquisition in life sciences, extraordinary demand in the secondary market, and friction surrounding the coding tool ecosystem—while these may appear as independent news items, they are connected by a single thread. It is the image of a rapidly growing company fighting on four battlefields simultaneously: business, politics, capital markets, and the developer ecosystem.

1. AnthroPAC—A Step Signaling the 'Escalation' of Political Activity by AI Companies

1-1. PAC Establishment and FEC Filing

Anthropic has submitted documents to the Federal Election Commission (FEC) to establish a PAC called 'AnthroPAC.' AnthroPAC plans to donate to both incumbent lawmakers and up-and-coming candidates from both parties in the midterm elections, with funds sourced from voluntary employee contributions (capped at $5,000).

1-2. The Context of Political Funding Across the AI Industry

According to reports from the Washington Post, AI companies have already contributed a total of $185 million to the midterm elections. Additionally, The New York Times has reported on 'Public First,' a Super PAC to which Anthropic is said to have contributed at least $20 million, with the PAC allocating funds to advertising campaigns supporting specific regulatory agendas.

1-3. The Background of Legal Disputes with the Pentagon

Anthropic's intensification of political activity coincides with a period in which the company is in the midst of a legal dispute with the Department of Defense. This dispute surfaced earlier this year regarding the government's use of Anthropic's AI models and their operational guidelines.

While OpenAI, Google, and Meta each have their own policy lobbying structures, Anthropic's political activity to date has been relatively modest. The establishment of AnthroPAC can be read as a move that clearly signals an intent to be directly involved in shaping AI regulation.

2. Coefficient Bio Acquisition—The Significance of a $400M Stock Swap, 8-Month-Old Startup, and ~10-Person Team

2-1. Overview of the Acquisition

Anthropic has acquired the stealth biotech startup Coefficient Bio in a $400 million stock swap (reported by The Information and Eric Newcomer; TechCrunch also confirmed the deal's completion).

Coefficient Bio was launched eight months ago by founders Samuel Stanton and Nathan C. Frey. Both have backgrounds in computational drug discovery research at Genentech's Prescient Design. The team of approximately 10 people is scheduled to join Anthropic's Health and Life Sciences division.

2-2. Connection to Claude for Life Sciences

This acquisition demonstrates a continued focus on the life sciences sector since the October 2025 announcement of “Claude for Life Sciences,” a tool designed to support scientific researchers in their discoveries.

What is noteworthy is 'speed' over 'scale.' Valuing an extremely early-stage team of about 10 people that was founded only eight months ago at $400 million shows strong conviction in both talent acquisition (acqui-hire) and technology. By combining computational drug discovery experts with a full-stack AI foundation, they are attempting to establish a position that can differentiate them from other companies in the AI-driven drug discovery process.

3. The 'Hardest-to-Get Stock' in the Secondary Market—Pentagon Conflict Actually Strengthens the Brand

3-1. An Abnormal State of $2 Billion in Waiting Buyers and Zero Sellers

The details shared with TechCrunch by Glen Anderson of Rainmaker Securities (an investment bank that handles private securities transactions for approximately 1,000 companies) vividly illustrate the current state of the secondary market.

'Anthropic is the hardest stock to get on our marketplace. There are no sellers,' Anderson stated. Bloomberg reports that while Ken Smythe, founder of Next Round Capital, says that 'buyers have $2 billion in capital ready and are waiting for Anthropic,' there is a situation where about $600 million worth of OpenAI stock remains unsold.

3-2. The Paradox Where Conflict with the Pentagon Functioned as "Differentiation"

Anderson argues that while the conflict between Anthropic and the DOD initially looked like a negative for the company, it ultimately became a gift. "The app became more popular, and people rallied around the company as 'heroes standing up to big government.' I think this event amplified the story and made the differentiation from OpenAI clearer," he stated.

3-3. The Positioning of OpenAI and Anthropic in the Secondary Market

OpenAI has not completely stalled either. While Anderson noted that "it's not a conversation about one or the other," he admitted that "it's not as active a market as Anthropic is right now." OpenAI's valuation in the secondary market is approximately $765 billion, trading at a discount from its primary round valuation of $852 billion.

3-4. The Risk of SpaceX IPO "Absorbing Liquidity"

Anderson pointed out that the SpaceX IPO will affect the timing of IPOs for OpenAI and Anthropic. SpaceX is planning an IPO for June 2026, aiming to raise $5 billion to $7.5 billion, having achieved a return of over 100x from its 2015 valuation of approximately $12 billion to over $1 trillion today. "SpaceX will soak up a massive amount of liquidity. The capital allocated to IPOs is limited," he said, suggesting that companies that go public first will have an advantage.

4. OpenClaw Billing Changes—Tensions Between Open Source and Closed Ecosystems

4-1. What Has Changed

Anthropic announced that starting at noon (Pacific Time) on April 4, 2026, Claude Code subscription usage quotas will no longer be applicable to third-party harnesses, including OpenClaw. Moving forward, a separate pay-as-you-go model will be required, distinct from the subscription. This policy begins with OpenClaw and will be applied sequentially to other third-party harnesses in the future.

4-2. Anthropic's Explanation

Boris Cherny, Head of Claude Code, stated on X that "our subscriptions were not designed for the usage patterns of these third-party tools," and explained that they are "intentionally trying to manage growth to continue providing sustainable service to our customers in the long term." He also stated that full refunds would be offered.

4-3. Criticism from the OpenClaw Founder

Meanwhile, OpenClaw founder Peter Steinberger (who has since moved to OpenAI) stated on X that he and OpenClaw board member Dave Morin "tried to persuade Anthropic, but could only get a one-week grace period." He criticized the move, saying, "First you copy popular features into your own closed harness, and then you shut out open source—the timing is interesting."

However, Cherny countered that the Claude Code team are "huge fans of open source," noting that he himself had just submitted a pull request to improve prompt cache efficiency for OpenClaw, and stated, "This is a matter of engineering constraints."

This incident raises the difficult question of how rapidly growing AI platforms should design their relationships with their ecosystems. Since trust from the developer community was one of Anthropic's points of differentiation, their future response will be closely watched.
