Pinterest bets $4 billion on Amazon.

$PINS Pinterest has signed a five-year, $4 billion contract with $AMZN — the largest infrastructure commitment in the company’s history. Graviton and Trainium chips, a full bet on AI.

But the real story is with Amazon. Its chip business generates over $20 billion annually and is growing at triple-digit rates. Trainium2 offers a 30% better price/performance ratio than comparable GPUs. Trainium3, delivered from early 2026, is almost fully pre-sold. Amazon is slowly freeing itself from dependence on Nvidia $NVDA.

With 631 million active users, Pinterest is shifting search from keywords to AI models that understand visual context. Ten consecutive quarters of double-digit user growth, revenue over $1 billion in Q1 2026. It’s fighting for survival against TikTok and Instagram and has bet on Amazon.

How do I see it?

Amazon is building chip infrastructure that genuinely competes with Nvidia and this is not marketing, these are the numbers. And the AI capex cycle isn't over. Commitment from OpenAI of $100+ billion, Trainium3 pre-sold before launch, now Pinterest with $4 billion. Infrastructure is being built for years to come.

$AMZN remains in the portfolio for a good reason.
