What Do You Have to Believe for SpaceX to Be Worth Over $2 Trillion?

For SpaceX's $2 trillion valuation to be justified, investors must believe in four core theses: cheap compute is the key, AI must beat commodity pricing, revenue must grow 25x in five years, and investors must still pay 30x free cash flow by 2030. The speaker argues that SpaceX's moat comes from its low-cost launch capability, which could enable vertically integrated AI data centers in space, funded by Starlink's profitable connectivity business. However, he cautions that these margins are far from guaranteed and that the company's massive capital expenditures and reliance on a few large customers pose significant risks.

These 5 Ad Stocks Die Before Google & Meta Do

Agentic AI will disrupt advertising businesses that rely on search and display ads, as agents replace human eyeballs, making ads worthless to merchants. The speaker argues that companies like People Inc., PubMatic, Magnite, Criteo, and The Trade Desk are highly exposed, while social media and TV ads remain safer because people still want to view content themselves. The key takeaway is to follow the eyeballs: if an ad is seen by a human, it's protected; if an agent can bypass it, the business model is at risk.

AI Agents Are Coming for These 5 Stocks

Agentic AI will cancel unused subscriptions, eroding revenue for companies that rely on forgotten recurring payments, argues Brian Stoffel. He identifies Planet Fitness, SiriusXM, Peloton, Dropbox, and GoDaddy as vulnerable, noting that even a small monthly churn compounds over time. The key takeaway for investors is to assess whether an AI agent would cancel a service; if so, the company's membership numbers may decline.

Micron Crushed Earnings. So Why'd It Still Fall?

Micron's blowout earnings, with revenue up 380% and gross margins nearly doubling to 87%, still led to a stock decline because investors focus on the sustainability of those margins. The speaker explains that even a drop to 75% gross margins would halve revenue, and the long-term average is 37%, so the key risk is when supply catches up with demand, especially with new capacity coming online in late 2028. He argues that the stock's cheap valuation (14x trailing earnings) reflects this uncertainty, and the real question is whether gross margins can stay elevated.

I Just Made This My Biggest Holding

Brian Stoffel argues that Meta Platforms is his largest holding because the market has priced in zero value for its AI ambitions, while its core advertising business is already benefiting from AI, with both ad impressions and prices rising simultaneously. He highlights Meta's new AI agent, Muse, which could generate subscription revenue and take a slice of transactions, potentially transforming the business. Despite the stock rising 30% since his purchase, he believes the valuation is still reasonable, with a reverse DCF suggesting modest growth expectations.
