The AI Boom Is Coming to Main Street
For three years, the biggest bets in AI have been made in private. Venture funds, sovereign wealth funds, and a handful of tech giants writing checks most investors could never access. This week, that started to change.
SpaceX filed an $80 billion IPO prospectus — the largest in history. OpenAI is days away from filing its own, targeting a $1 trillion valuation by September. The AI boom, which has been priced behind closed doors since ChatGPT launched in 2022, is about to land on public stock exchanges where anyone can participate.
What the Numbers Say
OpenAI just closed a $122 billion funding round at an $852 billion valuation. Amazon put in $50 billion. NVIDIA put in $30 billion. SoftBank put in $30 billion. The company now has 900 million weekly active ChatGPT users and $2.6 billion in monthly revenue.
To put that in context: $2.6 billion per month is $31 billion annualized. Two years ago OpenAI was a research lab. Today it's one of the fastest-growing businesses in history.
Microsoft raised its 2026 AI capital expenditure guidance to $190 billion — partly because memory and storage component prices are surging due to AI demand. The buildout is so large it's moving the price of the raw materials required to build it.
What This Means for You
The Nasdaq has gained seven of the last eight weeks. The AI infrastructure thesis we've been tracking since February — chips, power, networking, security — continues to be confirmed in earnings, in capital flows, and now in IPO filings.
The OpenAI IPO will be one of the most watched market events in years. When it lists, millions of retail investors will be buying AI exposure for the first time. Understanding what you're actually buying — and which companies control the infrastructure that makes all of it work — is the difference between investing and speculating.
That's what we track every week at MasicotAI.
