OpenAI is preparing to file a confidential S-1 with the SEC as early as this week, working with Goldman Sachs and Morgan Stanley, targeting a September 2026 public listing at a valuation above $1 trillion. The Wall Street Journal first reported the timing, with WinBuzzer narrowing the filing window to Friday. OpenAI has not confirmed.

Anthropic has told prospective investors it expects to post its first operating profit ever in the current quarter — $559 million on Q2 revenue of $10.9 billion, a 130% jump from the $4.8 billion reported in Q1. The numbers came via a Wall Street Journal scoop on Wednesday evening UK time and have been corroborated by CNBC and Dataconomy. The company is raising a fresh round at a $900 billion pre-money valuation and is reportedly targeting an October IPO.

SpaceX's own S-1 landed on Wednesday and contains a number worth circling. Anthropic has agreed to pay SpaceX $1.25 billion a month through May 2029 for access to Colossus 1 and Colossus II — a total commitment north of $45 billion and an annual run rate of $15 billion. The filing also shows SpaceX targeting $75 billion at IPO under the ticker SPCX, with a Nasdaq debut pencilled in for 12 June.

Google Marketing Live, which we covered briefly on Wednesday, has now been fully documented. The substantive announcements for performance marketers are Conversational Discovery ads inside AI Mode, Highlighted Answers in recommendation lists, AI-powered Shopping ads with Gemini-written explainers, Business Agent for Leads in open US beta, and the rebuilt Asset Studio with Gemini Omni for creative generation. AI Brief lets advertisers feed brand voice and guardrails to the system in plain English.

The connective tissue across the three financial stories is the cheap-AI thesis published by CNBC on Wednesday. Artificial Analysis benchmarks now put Claude at $4,811 per query, ChatGPT at $3,357, DeepSeek at $1,071, Kimi at $948 and Zhipu GLM at $544. Chinese models have grown from roughly 1% of OpenRouter usage in 2024 to over 60% in May 2026. The premium-moat IPO pitch is being tested in real time by the unit economics underneath it.

Watchlist: Anthropic's Dreaming feature and multi-agent orchestration for Managed Agents, both moved into public beta this month with credible enterprise pilot data from Harvey and Wisedocs. And Meta's 2026 capex guidance, now raised to $125–145 billion, sets the spending bar the rest of the field is being measured against.

The pattern across today's stories is that the AI sector is pricing itself for public markets in the same eight-week window that buyers are starting to walk towards cheaper inference. The procurement implications for a sharp operator are direct.

Google used last night's I/O keynote at the Shoreline Amphitheatre to ship Gemini 3.5 Flash as the new default across the Gemini app, AI Mode in Search, and the developer stack. Google's own benchmarks claim 3.5 Flash beats Gemini 3.1 Pro on Terminal-Bench 2.1, GDPval-AA, MCP Atlas and CharXiv Reasoning, while running at roughly four times the output-token speed of frontier rivals. Gemini 3.5 Pro is scheduled for June.

Gemini Spark, a 24/7 personal AI agent that runs on cloud virtual machines and works while devices are off, also landed. Spark is built on Gemini 3.5, runs inside Google's Antigravity development environment, and ships with Gmail, Calendar, Canva, OpenTable and Instacart integrations. It opens to trusted testers this week and to US AI Ultra subscribers next week.

Google restructured its AI subscriptions on the same stage. A new AI Ultra tier launches at $100 a month, and the existing top tier drops from $250 to $200. The Ultra tier bundles five-times-Pro usage limits in the Gemini app and Antigravity, priority Antigravity access, 20TB storage, YouTube Premium and Gemini Spark access.

Google Marketing Live opens its keynote today, Wednesday 20 May, at 4.45pm UK time, with Vidhya Srinivasan and Philipp Schindler on stage. The pre-show announcements are already material: AI Max for Search has formally exited beta with a stated 7% average uplift in conversions or conversion value at similar CPA or ROAS, and Dynamic Search Ads, automatically created assets and campaign-level broad match all begin forced migration to AI Max in September 2026.

Google also launched the Universal Commerce Protocol, an open standard for agentic commerce, backed by Shopify, Etsy, Wayfair, Target, Walmart, Adyen, American Express, Mastercard, Stripe, Visa, Best Buy, The Home Depot and Zalando. UCP is interoperable with Agent2Agent, Model Context Protocol and the Agent Payments Protocol. A consumer-side Universal Cart was demoed at I/O as the buyer-facing hub.

Gemini Omni, the company's new multimodal create-anything video model, also launched. Omni Flash is live now for AI Plus subscribers and higher, with ten-second clip caps, and rolls out free inside YouTube Shorts and YouTube Create later this week. An Omni Pro tier was teased.

The pattern running through the entire 48-hour Google window is that the AI stack has been collapsed into Google's distribution.

OpenAI and Dell Technologies announced a partnership yesterday to bring Codex and ChatGPT Enterprise into hybrid and on-premises environments through the Dell AI Data Platform and Dell AI Factory. The deal lands at the moment Codex weekly developer usage crossed four million and gives OpenAI a serious enterprise distribution answer to Claude Code.

Ramp's May 2026 AI Index, published yesterday, shows Anthropic overtaking OpenAI in US business spend for the first time. Anthropic's adoption climbed to 34.4% of tracked businesses in April; OpenAI fell to 32.3%. The engine is Claude Code — now reportedly the fastest-growing product in Anthropic's history and authoring roughly 4% of all public GitHub commits.

xAI quietly opened Grok Build to public beta over the weekend, an agentic CLI coding tool initially limited to SuperGrok Heavy subscribers at $300 a month, with a $99 introductory price for the first six months. Grok joins the coding-agent race against Claude Code, Codex and Google's developer stack — and is now the third paid CLI competing for engineering wallets.
