See this official SEC document? On page 146 Elon Musk revealed the name of a startup that Jeff believes will be…
The next monster IPO on Wall Street. Even though this has nothing to do with robots, self-driving cars, or rockets… this startup is growing faster than Tesla… faster than SpaceX… and even 23 times faster than Nvidia.
That’s why The Atlantic called it “the fastest-growing business in the history of capitalism.”

Two Trillion-Dollar IPOs Just Left the Calendar

SpaceX went public on June 12 at $135. It peaked at $225 four days later. It closed Friday at $152. That 32 percent retracement in twelve days just rewrote the AI IPO calendar. OpenAI is delaying to 2027. Its biggest rival cited the same reason. The largest listing year in history just lost its second and third acts.
The Breakdown
Today’s disagreement: private AI valuations say the boom is accelerating. Public AI markets say it is repricing. The IPO pipeline breaking tells you which side is under more pressure.
01
The SpaceX Correction
SPCX peaked at $225.64 on June 16, four days after listing. It closed Friday at roughly $152, near its IPO price. The $75 billion raise was the largest in history. The drawdown that followed is now cited by name in every AI IPO boardroom in Silicon Valley.
02
The Pipeline Breaks
On June 26 both the New York Times and Bloomberg reported that OpenAI is leaning toward delaying its IPO to 2027. CEO Sam Altman was described as “spooked” by the SpaceX correction. The company filed its confidential S-1 on June 8. It will not set a date.
03
The Valuation Gap
OpenAI’s last private round valued it at $852 billion. Altman will not accept less than $1 trillion at listing. Polymarket traders now put the odds of a 2026 OpenAI IPO below 30 percent. Private AI says the boom is accelerating. Public AI — the Nasdaq fell 4.6 percent last week — says it is repricing.

The IPO Pipeline That Was Supposed to Define 2026

Three Whales, One Calendar

Two weeks ago the AI IPO calendar looked historic. SpaceX had just priced the largest offering ever. OpenAI and its biggest rival had both filed confidential S-1s with the SEC within a week of each other. Combined private valuations north of $1.8 trillion were queued for public markets by year-end. Wall Street called it the “three-whale” event: three mega-cap AI listings draining global IPO liquidity across the second half.

Two of those whales just swam back out to sea.

What SpaceX’s Tape Actually Showed

SPCX priced at $135 on June 11. It opened at $150, peaked at $225.64 four days later, then gave back nearly all of its gains. It trades near $152. The mechanics mattered more than the level: 96 percent of shares remain locked until December. The float was thin. The run-up was options-driven. The correction, per JPMorgan, raised “concerns about sustainability of infrastructure spending given the delay in funding from the capital markets.”

In this tape, the SpaceX correction is not a stock story. It is a market-structure event. Every AI company watching that tape learned the same lesson: a thin float on a narrative-peak valuation produces a four-day party and a twelve-day hangover. OpenAI’s CFO Sarah Friar has reportedly been advocating for a 2027 listing since before the SpaceX result confirmed her case.

The Private-to-Public Pricing Gap Is the Signal

Our view: the disagreement that matters here is not between two AI companies and the market. It is between two entire pricing regimes. Private AI valuations — $852 billion for OpenAI, $965 billion for its closest competitor — have not repriced. The Nasdaq fell 4.6 percent last week. Chip stocks dropped Friday on the OpenAI delay itself, per CNBC. The 10-year Treasury yield fell to a seven-week low, pricing a growth deceleration that AI private rounds have not absorbed.

When the two most valuable private companies in a sector decline to go public, the capital that was earmarked for those listings does not disappear. It reprices and redirects. Some of it flows into private secondary markets. Some moves into the public AI names that still trade at a discount to the private marks. And some moves out of AI entirely and into the industrial, healthcare, and energy rotation that has quietly outperformed for three weeks running. The Dow rose 0.6 percent last week while the Nasdaq fell 4.6 percent. That gap is the rotation in a single number.

December Is the Deadline That Actually Matters

Worth watching: SpaceX’s lockup expires in December. When 96 percent of shares unlock, the supply dynamics change overnight. If SPCX is still near $152 at that point, early investors who saw $225 will be selling into a market that has already priced the correction. That second wave of selling is what the next AI company in the IPO queue is trying to avoid by waiting.

Before then: ISM Manufacturing this morning, JOLTS Wednesday, jobs Friday. If the macro data softens and the Nasdaq continues to rotate capital out of growth, the IPO window narrows further. If it stabilizes, one of the two delayed companies may move its timeline forward. Either way, the private-to-public pricing gap is the most important structural signal in AI right now. It will resolve. The question for every portfolio is which side reprices first.

The two most valuable private companies in AI just looked at the public market and decided to stay home. That is not a timing decision. That is a price signal.
