1. OpenAI’s First Custom AI Chip Is Here

What happened: On June 24, 2026, OpenAI and Broadcom unveiled Jalapeño — OpenAI’s first custom-built AI processor. It was designed in just nine months, which is reportedly a record for chips this advanced. Jalapeño was built specifically for inference — the process of running a pre-built AI model to answer your questions. Early testing shows 50% cost savings compared to standard AI GPUs, with better performance per watt.

What this means for you: Right now, every time you ask ChatGPT something, it runs on borrowed hardware — mainly Nvidia GPUs that weren’t originally designed with AI in mind. Jalapeño changes that equation. When OpenAI runs its own custom chips, two things tend to happen: the service gets faster, and costs go down. Those savings could eventually show up as cheaper subscriptions, more features on the free tier, or a more reliable ChatGPT during busy hours. OpenAI plans to deploy Jalapeño by end of 2026.

2. ChatGPT Loses Its Market Majority — For the First Time Ever

What happened: According to Sensor Tower’s State of AI 2026 report, ChatGPT’s global market share fell to 46.4% in May 2026 — the first time it’s dipped below 50% since launching in 2022. Google Gemini now holds 27.7% of the market, and Anthropic’s Claude has reached 10.3%. The growth numbers are striking: Claude alone went from 60 million monthly users in December 2025 to 245 million by May 2026 — a 4× jump in just five months.

What this means for you: The AI assistant market is no longer a one-horse race. If you’ve only ever used ChatGPT, now is a genuinely good time to try Gemini and Claude — both have improved dramatically. Claude is especially strong for long documents, research, and writing tasks. Gemini is deeply integrated into Android and Google Workspace. And with three serious competitors pushing each other, all of them will keep getting better, faster.

3. Apple Completely Rebuilt Siri — and Put Google Gemini Inside

What happened: At WWDC 2026 on June 9, Apple unveiled a completely rebuilt Siri, now officially called Siri AI. The new version gains full screen awareness — it can read what’s on your screen and act on it in real time. It also gets a standalone app to compete directly with ChatGPT and Claude, natural language email and text editing, and conversational memory. Under the hood: Google Gemini powers the intelligence.

What this means for you: If you own an iPhone, your AI assistant just got a genuine upgrade. The old Siri was notoriously bad at understanding complex requests. The new Siri AI can see your screen — so if someone texts you flight details, you can say “add this to my calendar and text mom the arrival time” and it handles the whole thing. The catch: it ships with iOS 27 in fall 2026, available for iPhone 11 and later. Older devices won’t get it.

4. Google Is Losing Its Best AI Researchers — And Fast

What happened: In the past two weeks alone, four of Google’s top AI researchers announced they’re leaving for competitors. Nobel Prize-winning AlphaFold creator John Jumper is heading to Anthropic. Gemini co-lead Noam Shazeer — co-author of the 2017 Attention Is All You Need paper that started the modern AI era — is joining OpenAI. And Gemini researchers Jonas Adler and Alexander Pritzel are also moving to Anthropic. These aren’t junior engineers — these are the people who built some of Google’s most celebrated AI breakthroughs.

What this means for you: Talent moves like these take time to play out in products, but they matter. The people who built Gemini are now working on Claude and ChatGPT. This likely means Anthropic and OpenAI’s models get meaningfully better over the next 12–18 months. For you as a user: don’t assume the AI tool you’re using today is still the best option six months from now. The rankings will keep shifting.

5. China Is Spending $295 Billion to Dominate AI

What happened: China announced a $295 billion, five-year national AI infrastructure plan — one of the largest government AI investments in history. That works out to roughly $59 billion per year directed at AI data centers, chips, research, and infrastructure. The announcement signals China’s intention to compete directly with the US for AI leadership at the national level.

What this means for you: You may not feel this directly, but it reshapes the AI landscape for everyone. More global competition means more open-source alternatives and faster innovation cycles. China has already released competitive open-source models like DeepSeek, which shook up the market when it launched. A $295 billion commitment signals that Chinese AI isn’t going to trail behind — it may become a serious alternative to US-based tools for users in many parts of the world.

The Bottom Line

The biggest theme this week: the AI market is fragmenting. For three years, “AI” basically meant ChatGPT. That era is over. We’re entering a phase where Apple, Google, Anthropic, OpenAI, and now the Chinese government are all fighting for the same space — and none of them is running away with it.

For users, this is genuinely good news. Competition drives improvement, drives pricing down, and keeps any single company from getting complacent. The worst thing that could have happened to AI was for one company to win unchallenged.

The Jalapeño chip is the quiet story worth watching most. When AI companies control their own silicon, they can iterate faster, cut costs, and build features that aren’t possible on off-the-shelf hardware. OpenAI owning its compute supply chain is a structural shift — not just a product announcement.

What to Watch Next

Claude Fable 5 pricing — Anthropic ended its free window for Claude Fable 5 on June 23. How users respond to the paywall will tell us a lot about the real willingness to pay for premium AI.
Jalapeño deployment — OpenAI plans to deploy the chip by end of 2026. Watch for performance improvements and pricing changes in ChatGPT once it rolls out.
Google’s next model — With four top researchers out in two weeks, Google’s next major model announcement will be under intense scrutiny.

Murphy’s Take

I’ve been watching the AI space for a while, and this week actually felt different. The ChatGPT-below-50% number is symbolic, but the reason matters more than the number itself. It’s not that ChatGPT got worse — it’s that Gemini and Claude genuinely got better. That’s healthy.

The Apple-Gemini partnership is the sleeper story here. Most iPhone users don’t actively choose an AI tool — they just use whatever’s on their phone. Embedding Gemini inside Siri hands Google 1+ billion passive users who never had to make a deliberate choice. That’s a distribution play no amount of marketing can replicate.

And the Jalapeño chip? The boring infrastructure story is almost always the one that matters most. If OpenAI can cut inference costs by 50%, that money has to go somewhere. I’m betting it goes into making the free tier actually useful again.
