Seven billionaire-founded or -led companies -- OpenAI, Anthropic, xAI, Anduril, Databricks, Prometheus and The Boring Co. -- raised more than $260 billion through the first 10 months of 2026, just over half of all U.S. seed-through-growth venture investment.
Elon Musk is renaming SpaceXAI to SpaceXSI, The Information reports, swapping "AI" for "SI" -- super intelligence -- across the combined SpaceX-xAI entity formed in February's $1.25 trillion merger.
OpenAI, Anthropic, Google, Meta, Nvidia and xAI signed a voluntary White House safety accord as Trump ordered agencies to rename AI "Super Intelligence," a largely symbolic pact with no enforcement mechanism.
Court filings in OpenAI's antitrust fight with xAI reveal OpenAI's own view that its ChatGPT integration into Apple's Siri was 'persistently underperforming,' undercutting xAI's claim the deal gave OpenAI an unfair advantage.
xAI released Grok 4.7, a 2.1-trillion-parameter reasoning model with a 500K-token context window priced at $2 per million input and $6 per million output tokens, deployed immediately across all GitHub Copilot plans.
A federal judge ordered Elon Musk's X Corp and SpaceXAI to privately disclose the terms of an undisclosed settlement with Apple by noon Thursday, after the companies dropped Apple from their OpenAI antitrust suit without explanation.
Anthropic CEO Dario Amodei is urging AI companies to deliberately slow the pace of capability gains, and OpenAI's Sam Altman and xAI's Elon Musk both said within hours that they agree.
Contract documents obtained via a FOIA lawsuit reveal OpenAI, Anthropic, Google and xAI agreed to far closer Pentagon partnerships than their public statements suggested, including training military personnel and forecasting the risks of their own technology.
Booz Allen's benchmark scored Anthropic's Claude Mythos at 80 on its Cyber Weapon Index -- the only model of 18 tested to autonomously complete a full cyberattack kill chain -- well ahead of xAI's Grok-4.5 at 49 and OpenAI's GPT-5.6 Sol at 46.
Since its record $75 billion June IPO, SpaceX has used its newly public stock to fund an all-stock merger with xAI and a $60 billion acquisition of Cursor-maker Anysphere -- the most aggressive post-IPO acquisition spree of any 2026 debut.
GitSpawn, a newly disclosed vulnerability class, lets a booby-trapped repository silently execute code the moment it's opened in an AI coding agent, with no click or prompt required.
The Defense Department's GenAI.mil platform now offers custom ChatGPT and Grok versions to 3 million military and civilian personnel, with 1.7 million already signed up, cleared to handle sensitive but unclassified government work.
The SpaceX merger hands Grok something no other frontier lab has: effectively unlimited capital plus a built-in distribution channel in X. That's the bull case. The bear case is the math — $6.4B burned in a single year on ~$3.2B of revenue, and analysts openly calling the deal 'value destruction.' xAI is the riskiest of the frontier labs: it has the most powerful patron and the least disciplined balance sheet. Whether Musk's bundle outruns the burn is the whole story.
xAI makes money through Grok consumer subscriptions (SuperGrok, sold via the X app), API access, and enterprise deals — with deep integration into X (formerly Twitter) providing both distribution and a live stream of training data. Following the February 2026 merger, the whole operation is now backstopped by SpaceX's capital and compute.
The strategic bet is that owning distribution (X) plus capital (SpaceX) plus talent lets Grok close the gap with OpenAI and Anthropic despite a later start and heavy burn. The wager is that vertical integration into Musk's ecosystem is worth more than the years of head start its rivals enjoy.
