Anthropic's Landlord Is Underwater

On July 17, SpaceX stock fell below its $135 IPO price for the first time — down roughly 40% from its June peak — even as Anthropic schedules fall IPO investor meetings and still owes Musk's firm $1.25 billion a month to rent Colossus compute with a 90-day escape hatch.

Thesis July 17's SpaceX breach below IPO price just turned Anthropic's $45 billion Colossus lease into a market stress test: the Claude maker is lining up October IPO meetings while its largest landlord trades underwater, 27 Wall Street analysts cling to $242 targets on a 4% float, and Kimi K3 repricing proves the compute scarcity thesis that justified both bets may already be cracking.

SpaceX shares fell below their $135 IPO price on July 17 — down roughly 40% from a June 16 peak near $226 — even as Anthropic schedules investor meetings for a possible October listing and still pays Elon Musk's company $1.25 billion a month to rent Colossus compute, making the AI economy's most awkward landlord-tenant relationship the clearest signal yet that the infrastructure trade is repricing faster than the IPO parade can keep up.

The slide: SpaceX (NASDAQ: SPCX) touched its lowest level since its June 12 Nasdaq debut, falling 5.4% on July 17 to below $126, the Associated Press reported. Investors who bought at the $135 offering price are now underwater. The stock has shed roughly 40% since peaking at $225.64 on June 16 — five weeks after the record $75 billion IPO that was supposed to reopen the mega-tech listing window.

  • Short interest has climbed above 17%, The Epoch Times reported, as traders bet the selloff has further to run.
  • SpaceX's $25 billion bond due in 2056 has seen prices fall sharply, lifting yields toward 8%.
  • A July 17 Starship test abort — Musk said on X that "some of the engines didn't start, triggering an automatic launch abort" — added to the week's pressure.

The lease: SpaceX's S-1 filing disclosed that Anthropic agreed to pay $1.25 billion per month for access to Colossus and Colossus 2 data-center capacity in Memphis, Tennessee — a deal the filing describes as running through May 2029, with either party able to terminate on 90 days' notice.

  • At the headline monthly rate, the contract could generate up to $45 billion over three years — making Anthropic SpaceX's single largest disclosed AI customer.
  • Musk contradicted the multi-year framing on May 28, writing on X that SpaceX "has not committed to leasing Colossus for years" and describing a 180-day base term with 90-day mutual cancellation thereafter.
  • TechCrunch noted the S-1 language — "the customer has agreed to pay a monthly fee through May 2029" — appears four times in the filing, while Musk's public posts describe a far shorter commitment.

The timing: On July 15, CNBC and Bloomberg reported that Goldman Sachs, Morgan Stanley, and JPMorgan Chase are scheduling meetings between Anthropic executives and prospective investors ahead of a possible October IPO. Anthropic confidentially filed its S-1 on June 1 and was last valued at $965 billion in a May Series H round. An Anthropic spokesperson declined to comment.

  • OpenAI has reportedly pushed its own listing target to 2027, leaving Anthropic first in line if markets cooperate.
  • WinBuzzer reported July 17 that Anthropic is separately negotiating several billion dollars in added bank credit atop a $2.5 billion facility — another sign the company is stress-testing balance-sheet capacity before going public.

The analyst gap: Tokenist reported that 27 of 31 Wall Street analysts covering SPCX rate the stock Buy or Strong Buy, with a consensus price target near $242 — implying roughly 90% upside from the July 15 close. Needham this week maintained Buy and raised its target to $250.

  • Prominent investor Gary Black posted on X July 15: "$SPCX now below $133. IPO should not have been priced at $135 (EV/Rev 47x!). Hard for me to get excited until it falls below $100."
  • Economist James Foord warned in a July 16 note: "Don't be tempted to buy the dip yet," citing a valuation premium SpaceX cannot justify without near-term profitability.
  • Swissquote senior analyst Ipek Ozkardeskaya told The Epoch Times that SpaceX "is now heading straight down as investors realize the company will have to spend heavily — perhaps for many years — to achieve an ambitious dream."

Why now: Moonshot AI's July 16 Kimi K3 release — a 2.8-trillion-parameter open-weight model ranked near U.S. frontier systems — accelerated a global chip selloff that had already punished TSMC, Nvidia, and the Philadelphia Semiconductor Index. The AP tied SpaceX's slide directly to the broader AI repricing, not just rocket delays.

  • JR Research strategists told The Epoch Times that Anthropic's Colossus lease helped drive "an early growth inflection" in SpaceX's AI revenue — but added that having spare compute "is proving to be invaluable" only while scarcity holds.
  • If Kimi K3 and successive Chinese open models compress frontier pricing, the scarcity premium underwriting both the Colossus rent check and the SpaceX IPO thesis weakens simultaneously.

Convina's view: Anthropic's fall IPO roadshow is pitching a $965 billion AI champion whose largest disclosed infrastructure bill goes to a landlord whose public stock just broke below par — on a lease either side can exit in 90 days. That is not a footnote for the S-1 risk factors section; it is the story. Wall Street's $242 consensus on SpaceX assumes AI infrastructure scarcity lasts long enough to validate $1.25 billion monthly rents and trillion-dollar lab valuations at the same time. Kimi K3 suggests the opposite. Until Anthropic discloses how much of its compute stack survives a landlord default or a Musk recall, investors are being asked to price the most important AI IPO of the decade while staring at a counterparty trading 40% off its peak — and both sides hold the kill switch.
