OpenAI DevDay: Dots, Agents & $100B Opportunities

I watched almost 60 minutes of Sam Altman on stage at OpenAI Dev Day 2026. Out of 20-plus launches, I pick the three or four that I think can make people billions of dollars in aggregate. I break down Dots, OpenAI's personal agent platform, plus the Decisions API, the Agents API with computer use, and Sign in with ChatGPT. I also share my four-step framework for building in this world and two business ideas I hope someone takes. If you want to build a business and make money around AI, this episode is for you.

Key Points

• Dots gives plugin builders a front door to 1.2 billion weekly active users.
• OpenAI is doubling down on plugins to make ChatGPT the app ecosystem for AI.
• Sign in with ChatGPT lets users bring their current plan, so a free core app with paid upsells now works.
• Workflows too niche for OpenAI to build become viable businesses.
• The strongest businesses in this world own the trigger, the action, and the feedback.
• Two open opportunities: real-world work APIs and an analytics layer for agent discovery
