The claim is supported by two mutually consistent sources available in this run: The Kobeissi Letter X post and the crypto.news article. The X post is the strongest available source here because it explicitly contains all key elements of the claim, including the 733% increase since October 2025 and the statement that the Jupiter instruments are backed 1:1 by SPV exposure. The crypto.news article independently corroborates the $1 trillion implied valuation and 733% rise. However, because neither source is an official Anthropic or Jupiter statement and no primary market documentation was retrieved, confidence is medium rather than high.
