Anthropic describes him as one of the principal authors of the neural scaling laws that have shaped the development of large language models. It says he also helped pioneer Constitutional AI.<ref name="s1a2" /> The amended registration statement of 10 November 2026 showed him as the beneficial owner of 242,351,170 Class A shares.<ref name="s1a2" />

== Education and academic career ==
Kaplan has a bachelor's degree in physics and mathematics from [[Stanford University]] and a PhD in physics from [[Harvard University]].<ref name="s1a2" /> [[Forbes]] says his research has focused on quantum gravity and machine learning. He became a professor at [[Johns Hopkins University]] in 2012 and is on leave.<ref name="fp_jared_kaplan" /> Anthropic's filing calls him an associate professor of physics at Johns Hopkins, where he taught courses on the foundations of deep learning.<ref name="s1a2" />

== Research ==
Kaplan was first author of ''Scaling Laws for Neural Language Models'' (2020). The paper reported that language-model loss scales as a power law with model size, dataset size and the compute used for training.<ref name="scal20">Jared Kaplan et al., [https://arxiv.org/abs/2001.08361 Scaling Laws for Neural Language Models] ''arXiv:2001.08361'', 23 January 2020, accessed 10 November 2026.</ref> He was also an author of the GPT-3 paper ''Language Models are Few-Shot Learners'' (2020) and of Anthropic's ''Constitutional AI: Harmlessness from AI Feedback'' (2022). The second paper describes training an assistant with oversight provided only through a list of rules or principles.<ref name="gpt3">Tom B.

It said that the seven co-founders had each pledged to give 80% of their personal Anthropic equity to philanthropy, describing the pledges as voluntary and revocable rather than legally binding.<ref name="s1a2" /> A single Class F share held by a founders' LLC will carry 50.1% of the votes.<ref name="s1a2" /> [[TechCrunch]] reported that each co-founder would sell 3,378,378 shares in the offering, worth just under US$250 million each at the midpoint of the range.<ref name="tc26">Julie Bort, [https://techcrunch.com/2026/11/10/all-7-anthropic-founders-will-each-cash-out-about-250m-in-ipo/ All 7 Anthropic founders will each cash out about $250M in IPO] ''TechCrunch'', 10 November 2026, accessed 10 November 2026.</ref> ''Fortune'' estimated that each co-founder owned about 1.4% of the company on a fully diluted basis.<ref name="fort26">Nick Lichtenberg, [https://fortune.com/2026/10/26/anthropic-ipo-cofounders-how-rich-billionaires-philanthropy-amodei/ Anthropic’s 7 cofounders are each worth $14 billion already—and that could double in an IPO.

Anthropic's filing says that in February 2026, after the company stated that its technology should not be used for mass domestic surveillance or fully autonomous weapons, the President directed federal agencies to stop using it and the Secretary of War ordered it designated a "supply-chain risk to national security". A federal district court in California largely granted Anthropic summary judgment on 27 August 2026, but on 25 September 2026 a divided D.C. Circuit panel upheld one of the designations. Anthropic has asked for a rehearing by the full court.<ref name="s1a2" />
