🚨 Breaking (last 24h)

OpenAI Claims First AI-Autonomous Math Breakthrough

OpenAI announced that one of its general-purpose reasoning models has autonomously solved an 80-year-old open problem in discrete geometry β€” the "ErdΕ‘s problem" β€” disproving a long-held belief about optimal grid-like constructions. The company published companion remarks from mathematicians Noga Alon, Melanie Wood, and Thomas Bloom (who maintains the ErdΕ‘s Problems website) validating the proof. This marks what OpenAI calls "the first time AI has autonomously solved a prominent open problem central to a field of mathematics." The proof came from a general-purpose model, not a math-specialized system.

OpenAI Barrels Toward September IPO

Sam Altman is reportedly targeting a September IPO for OpenAI, working with Goldman Sachs and Morgan Stanley. The company may file confidential IPO paperwork within days or weeks. This comes as SpaceX (which absorbed xAI) is also preparing its own IPO filing β€” setting up a Musk vs. Altman battle in public markets.

Anthropic to Pay xAI $1.25 Billion Per Month for Compute

SpaceX's S-1 filing revealed Anthropic will pay xAI $1.25 billion per month through May 2029 for compute capacity β€” a deal potentially worth over $40 billion total. The arrangement allows xAI to monetize unused capacity from its Colossus data center. Either side can terminate with 90 days' notice. The deal highlights xAI's "neocloud" hybrid model: building data centers for itself while reselling excess capacity to competitors.

xAI Lost $6.4B in 2025 on $3.2B Revenue

SpaceX's IPO filing reveals xAI's financials for the first time: $6.4 billion operating loss in 2025 on just $3.2 billion revenue. Losses ballooned from $1.56B in 2024. Revenue includes $365M from X/Grok subscriptions, $88M data licensing, and $116M advertising. AI capex hit $7.7B in Q1 2026 alone (annualized ~$30.8B). Grok MAUs: 117 million as of March 2026. SpaceX plans to scale Grok to "multiple trillions of parameters."

πŸ“Š Market Moves (last 48h)

Nvidia Posts Record Quarter, $43B in Startup Stakes

Nvidia reported record Q1 FY2027 revenue of $81.6 billion (up 20% QoQ), with data center revenue hitting $75.2 billion. The company authorized $80 billion in share repurchases. Notably, Nvidia's privately held startup stakes nearly doubled from $22B to $43B in a single quarter, driven by $18.5B in purchases. Nvidia committed $30B to OpenAI in February. Jensen Huang highlighted "significant" pending buildout with Anthropic: "Our coverage for Anthropic had been largely zero until this."

NanoClaw Creator Turns Down $20M Buyout, Raises $12M Seed

Gavriel Cohen, creator of NanoClaw (a secure sandboxed alternative to OpenClaw), raised a $12M seed round led by Valley Capital Partners with participation from Docker, Vercel, Monday.com, Slow Ventures, and Hugging Face CEO Clem Delangue as an angel. Cohen went from first lines of code to term sheet in under six weeks, fielding ~50+ investor DMs after endorsements from Andrej Karpathy and Singapore's foreign minister. He declined a roughly $20M acquisition offer.

Figma Adds AI Agent to Collaborative Canvas

Figma launched an AI assistant that uses natural language prompts to generate designs, edit existing ones, and automate tasks like generating iterations. Users can deploy multiple agents simultaneously. The agent runs on design-fine-tuned AI models. Figma Q1 2026 revenue: $333.4M (up 46% YoY). The company acquired Weavy last year and is bringing design and code closer together.

IrisGo (Andrew Ng-Backed) Launches AI Desktop Buddy

IrisGo, co-founded by former Apple Siri engineer Jeffrey Lai and backed by Andrew Ng, launched an AI desktop buddy that learns tasks by demonstration. Users show the app how to do something once, and it automates the process. Includes a coding assistant similar to Codex/Claude Code. The startup aims to become the "AI desktop buddy you never knew you needed."

Google I/O 2026 Recap (May 19)

Google's I/O conference delivered a massive AI overhaul:

xAI Sued Over Data Center Generators

The NAACP sued xAI for operating dozens of unregulated gas turbines near Memphis, Tennessee. xAI is using 46 turbines (only 15 permitted). Each can emit >2,000 tons of NOx annually. The EPA ruled xAI is violating federal law. Despite this, SpaceX's IPO filing reveals xAI plans to buy $2.8B more turbines β€” including $2B specifically for "mobile gas turbines."
