Google Universal Cart & the Universal Commerce Protocol are Google’s bid to become the operating system of e-commerce ⚙️🛍️; OpenAI is paying for YC’s next batch in tokens it prints itself 🫣💸

FinTech is Eating the World, 21 May

Hey Everyone,

Good morning & happy Thursday! Today’s issue is especially interesting as we’re diving deep into Google, which is now going all in to become the operating system for the whole e-commerce (what Google Universal Cart is all about, why it matters & how it can transform e-commerce forever + bonus deep dives into Google’s UCP, how it just won Agentic Commerce & why AmEx skipped the protocol race altogether inside), OpenAI that just found a way to turn inference compute into venture capital (what their deal with Y Combinator is all about, what are the risks & challenges here + bonus deep dive into OpenAI, which is now trying to kill the FinTech app economy & how Anthropic told AI founders exactly what to build in 2026 inside). So let’s jump straight into the finnovative stuff 🌶️

Google Universal Cart and the Universal Commerce Protocol are Google’s bid to become the operating system of e-commerce ⚙️🛍️

The BIG News 🔥 Arguably one of the most consequential announcements at I/O 2026 wasn’t another AI model. It was a shopping cart.

Google GOOGL 0.00%↑ is no longer content to sit at the top of the funnel. With Universal Cart and the Universal Commerce Protocol (UCP), it’s clearly making a play to own the entire commerce stack: the intent layer, the reasoning layer, and now the protocol layer that connects every merchant to every AI agent.

The pattern is unmistakable if you’ve watched Google before. Define the open standard. Get the ecosystem to adopt it. Then win on the implementation no one else can match.

Let’s dive deeper into this, break down how the product works, what UCP actually standardizes, who benefits, who gets squeezed, and the specific second-order effects investors and operators should be tracking over the next 12 to 24 months.
