The filing follows March 2026’s $122B raise at an $852B valuation, with Goldman Sachs and Morgan Stanley as underwriters. A fall 2026 listing is possible. When the public S-1 drops, it will be the first audited look at revenue by segment (ChatGPT consumer vs. enterprise vs. API). That $852B would slot OpenAI into the top 15 of the S&P 500. Source.

At WWDC on June 8, Apple announced a roughly $1 billion-per-year Gemini licensing deal (per Bloomberg) and a new Extensions framework in iOS 27 that lets users set Claude or ChatGPT as the default for all Apple Intelligence features. That ends OpenAI’s exclusive arrangement. Claude gets opt-in access to 2.5B+ active Apple devices for the first time. Coverage.

Upsized from $80B, the raise tops Petrobras’s 2010 record. Berkshire Hathaway put in $10B. The capital backstops Google’s $180–190B capex forecast for 2026. Public-market appetite for AI infrastructure spending at that scale is no longer speculative. Source.

Parallel subagent orchestration is now live: Claude Code breaks tasks into subtasks and runs them concurrently. If you do multi-file refactors or parallel test suites, this changes how you structure the work. Direct competitor to Cursor’s built-in agent mode and Cline’s parallel execution. Anthropic blog.

The decision tree comes down to scope: SDK custom tools for single-editor workflows, MCP servers when multiple clients or external services need the same capability. If you’re on Cursor v3.7+ and wondering which path to take, this guide walks the tradeoffs with code. Read the Cursor SDK guide.

When a task needs to cross service boundaries, run on a schedule, or share state across tools, Make picks up where a Cursor custom tool stops. Webhook triggers, 2,000+ integrations, visual flow builder. Try Make.

The Copilot SDK hit GA on June 2 with a stable API, BYOK support, and new Rust and Java language bindings. If you build internal dev tools or code-review bots, this guide covers what you can actually build, how AI Credits billing works, and when a custom Copilot extension beats standing up your own agent. Read it.

Every Copilot subscriber migrates to Polaris automatically in August, with a 3-month opt-out window to stay on GPT-4. If your team is deciding between Copilot and Claude Code today, this comparison covers what the model change means for the call, before Polaris benchmarks are public. Read the comparison.
