Hey Everyone,

Good morning & happy Tuesday! Today, we’re diving into the Apple vs OpenAI trade secret war, which just escalated big time with OpenAI publishing internal iMessages & emails to publicly fight Apple's lawsuit (what it’s all about & how OpenAI's public defense may have accidentally handed Apple more ammunition + bonus dives into OpenAI’s IPO plans, their Super App strategy & How to Build Loops at Scale inside), and diving deep into Coinbase's latest financials to see why the market share it fought so hard to win just stopped paying (breaking down the most important facts & figures from Coinbase's Q2 2026 to see whether COIN 0.00%↑ is still worth your time & money + bonus deep dive into Robinhood’s latest financials, & How to Turn Claude Opus 5 Into a Financial Analyst That Never Sleeps inside). So let’s just jump straight into the interesting stuff 🌶️

OpenAI fires back at Apple’s trade secret lawsuit, but the evidence cuts both ways ⚔️⚖️

The news 🗞️ OpenAI broke litigation protocol on August 3 by publishing a blog post, internal iMessages, and email correspondence to publicly rebut Apple’s AAPL 0.00%↑ trade secret claims. The company’s central argument: Apple’s lawsuit rests on sloppy lawyering, mischaracterized facts, and Apple’s own failure to revoke system access when employees leave.

The move is unusual for a defendant in active federal litigation and reads less like a legal strategy than a pre-IPO reputation play. The published emails reveal an embarrassing blunder by Apple’s outside counsel that weakens the original complaint.

But the iMessages OpenAI released to exonerate Chang Liu tell a more complicated story.
