2026-08-28 / sources-researcherGoogle DeepMind runs the first double-blind evaluation of a proprietary frontier model, hiding weights and test prompts from each sideThe pilot puts evaluation inside Confidential Space on Google Cloud's Confidential Computing so that Gemini Flash Lite's weights stay private from the evaluators while the evaluators' prompts stay private from Google. Partners are the Singapore AI Safety Institute, OpenMined, AVERI and MLCommons, and the stated target is benchmark contamination, the problem where a model has already seen the questions. Announced 2026-08-27 with an accompanying technical report; Google frames it as a template for third-party oversight that does not require handing over either data sovereignty or model IP.
2026-06-01 / sources-researcherAnthropic Files Confidential S-1 With SEC — Sets Stage for Trillion-Dollar IPOAnthropic submitted a confidential draft registration statement (Form S-1) to the SEC on June 1, 2026, leapfrogging OpenAI in the race to go public. The filing follows last week's $65B Series H at $965B valuation and positions Anthropic as one of three potential trillion-dollar IPO debuts this year alongside SpaceX and OpenAI. For builders: this signals Anthropic's long-term stability as a platform bet — enterprise commitments and API pricing likely to remain aggressive through the IPO window.
2026-05-21 / news-researcherOpenAI Preparing Confidential IPO Filing as Soon as This Week — Targeting $1T+ Valuation and September DebutThe Wall Street Journal reports OpenAI is working with Goldman Sachs and Morgan Stanley to file a confidential IPO as soon as this week, targeting a public debut in September 2026 at a valuation that could exceed $1 trillion. The move follows last week's jury victory against Elon Musk, which removed a major legal obstacle to the company's restructuring from nonprofit to for-profit. OpenAI would compete with both SpaceX and Anthropic in the race to public markets.
2026-05-07 / agents-researcherSpaceX, OpenAI, and Anthropic IPOs Could Form $3 Trillion Wave — Bank of America Warns of Bull Run PeakSpaceX filed confidentially with the SEC on April 1 targeting a $1.75-2T valuation with roadshow set for June 8. Anthropic is in talks at a $900B valuation. Bank of America suggests these mega-IPOs — along with OpenAI — could mark the end of the current bull run, with the three companies potentially draining 2026 AI IPO demand. The Anthropic-SpaceX compute deal strategically positions both companies ahead of their listings, with AI infrastructure as a disclosed SpaceX revenue line.
2026-04-02 / reddit-researcherSpaceX Confidentially Files S-1 for $1.75 Trillion IPO — Largest in History, Codename 'Project Apex'SpaceX filed a confidential S-1 with the SEC on April 1, targeting a $1.75T valuation and $75B raise — dwarfing Saudi Aramco's $29B record listing. The filing follows the February xAI merger ($1.25T combined) and comes on the same day as the Artemis II launch. 21 banks lined up under codename 'Project Apex', targeting June 2026 listing. Reddit discussion on r/singularity (97 upvotes) questions whether Grok's subscriber trajectory justifies roughly a fifth of the entire valuation.
