SpaceX Steals the Show
Elon Musk's SpaceX dominated the tape today, and not just from the launchpad. Fresh off the biggest stock market debut ever — a record $1.77 trillion IPO, per The Motley Fool — the aerospace-and-AI company rocketed to a $2.6 trillion valuation in just three trading sessions, briefly leapfrogging Amazon to become the world's fifth most valuable company. Shares added 4% in the latest session, and CNBC reports Wall Street is openly wondering whether SpaceX could trace the same explosive arc that turned Nvidia into a household name.
The company isn't waiting to find out. Reuters reports SpaceX is acquiring Anysphere, the startup behind the wildly popular AI coding assistant Cursor, in a deal valued at $60 billion. The move plants SpaceX squarely in the path of OpenAI and Anthropic, signaling that Musk intends to compete on AI software as aggressively as on rockets.
Nvidia Feels the Squeeze
The other side of the AI trade looked shakier. Barron's says Nvidia stock is "braced" as investors question how long the industry's spending spree can last, with the shares wobbling as the AI money spigot shows signs of tightening. That has analysts revisiting the long game: a widely circulated comparison weighs Nvidia against Alphabet to decide which AI chip stock is the better five-year bet. And The Motley Fool makes the case for a quieter winner — arguing the AI boom's biggest beneficiary may not be the GPU maker everyone names first.
AMD, Intel and the TSMC Bottleneck
Nvidia's rivals had a better day. AMD and Intel shares both climbed as available manufacturing capacity at TSMC tightened — GuruFocus and TradingView framed the gains around the same dynamic, with scarcer foundry slots boosting the value of chipmakers that have secured supply. AMD has been the standout of 2026, up a blistering 149% year to date according to AOL.com, riding the same AI-chip demand wave that lifted the sector.
OpenAI's Math Problem
Leaked numbers gave the bears fresh ammunition. Per TechSpot, OpenAI generated $13.07 billion in revenue but burned through roughly $21 billion — hard figures behind the long-held suspicion that the ChatGPT maker is spending far faster than it earns. The gap underscores why investors are suddenly so focused on whether AI's capital outlays can be sustained.
Startups Still Drawing Big Checks
Despite the jitters, money kept flowing to young companies. Amazon, Nvidia and AMD are jointly pouring $310 million into Odyssey ML, a world-model startup now valued at $1.45 billion — a rare case of three chip heavyweights backing the same bet. And Pramaana Labs raised a $27 million seed round led by Khosla Ventures, pitching technology to make AI output provably reliable, a problem that grows more urgent as the models spread.
The through-line: capital is rotating, not retreating. SpaceX's debut and shopping spree, the chip-supply scramble, and OpenAI's leaked losses all point to an AI market sorting winners from the merely expensive.
