Anthropic told investors it expects to more than double revenue to $10.9 billion in Q2 and post its first-ever operating profit, driven by surging professional demand for Claude.

The profitable quarter may not hold. Large compute costs scheduled later in the year could push Anthropic back into the red, making this a milestone rather than a turning point.

The timing is pointed: Anthropic's profitability news landed the same day OpenAI was reported to be filing for its IPO, making the AI race's financial scorecard suddenly very public.

SpaceX's S-1 reveals a $1.75 trillion valuation, a $75 billion raise target, and a company that lost $4.9 billion in 2025 on $18 billion in revenue, with Starlink generating over half of that.

The filing shows SpaceX funneled 60% of its 2025 capital spending into its AI division (Grok's home base), which lost billions and grew revenue just 22%, well below other frontier AI labs.

Musk will hold CEO, CTO, and board chair roles post-IPO and keeps 85% of voting power. His new comp package unlocks a billion shares if SpaceX hits $7.5 trillion and puts a million people on Mars.

Sam Altman offered every startup in YC's current 169-company cohort $2 million in OpenAI tokens in exchange for equity, structured as an uncapped SAFE that converts at the startup's first priced round.

OpenAI gets two things: equity upside if startups succeed, and a captive customer base building on its platform rather than defaulting to rivals like Anthropic or Google.

As inference costs keep falling, the tokens OpenAI is handing out today may cost it almost nothing to deliver tomorrow, making the equity it gets back look like a very good deal for Altman's side.

Spotify is launching an ElevenLabs-powered audiobook creation tool in beta this June, letting authors generate and self-publish AI-narrated audiobooks directly through its Spotify for Authors platform.

The integration upgrades Spotify's existing ElevenLabs partnership, giving authors access to newer, more expressive voice models than its previous Google Play Books narration option.

Spotify's audiobook push is working: listening hours are up 60% year-on-year, over a million Audiobook+ subscriptions are active, and the platform is tracking toward $100 million in annualized revenue.

OpenAI's unreleased general reasoning model disproved a grid-based theory tied to Erdős' 1946 unit distance problem, a belief that had shaped the field for 80 years, verified by three prominent mathematicians.

The solution came from a general-purpose model using algebraic number theory, not a math-specific system, distinguishing it from tools like DeepMind's AlphaProof built explicitly for formal math.

OpenAI calls math a "leading indicator" of what's coming. A general model making original discoveries, not just finding answers, is the earliest signal yet of AI that can contribute across fields autonomously.
