SPCX opens tomorrow — the retail allocation question becomes the precedent the next AI IPO cohort has to plan around
When SpaceX/xAI's NASDAQ debut lands at $135 a share and $1.75T valuation tomorrow, 30% retail allocation across three brokerages goes live. The mechanics of how that allocation plays out will define how Anthropic, OpenAI, and the next cohort structure their own retail tranches.
SPCX begins trading tomorrow on Nasdaq at $135 a share — $1.75 trillion valuation, $75B raise, officially the largest IPO in market history. The pricing happened this morning. The trading mechanics — and specifically the retail allocation through Robinhood, Fidelity, and Schwab — go live with the open. That's the inflection point the next 12 months of AI IPO planning runs through.
The retail allocation mechanic
30% retail across three brokerages with ~$250B in subscription demand against a $75B raise means a 3.5-4x oversubscription. Each broker's allocation algorithm becomes the bottleneck for individual access. Robinhood is expected to use proportional allocation; Fidelity a lottery for retail tickets; Schwab a relationship-tiered model. The composition of who actually gets shares — small retail vs. large brokerage clients vs. institutional through retail channels — sets the precedent for how the SEC and the labs themselves think about retail AI exposure.
Why Anthropic's retail structure will look different
Anthropic's $965B Series H confidential filing in May positioned the lab for an IPO. OpenAI's within-a-year timeline says the OpenAI IPO is the closest comparable. Both face a question SpaceX/xAI doesn't: there's no infrastructure cash flow underneath. Anthropic and OpenAI will be priced as pure-play frontier-AI bets. Retail allocation for that kind of asset reads differently than retail allocation for a Musk-controlled bundle that includes Starlink's $11.4B revenue stream.
The valuation anchor is now public-market
SpaceX/xAI at $1.75T resets every comparable. Anthropic at $965B and OpenAI projected at $500B-$1T pre-IPO now look comparatively cheap against a live public-market reference. That doesn't mean the next IPOs price up; it means the conversation around their pricing has a real-time anchor for the first time. The bull case becomes "trade close to the SpaceX/xAI public multiple"; the bear case is the Morningstar-style $780B fair-value flag that says the SpaceX/xAI trade itself is rich.
The Cursor/SpaceX wrinkle matters more than people think
SpaceX holding a $60B acquisition option on Cursor means SPCX's public valuation includes embedded developer-tools optionality on top of Starlink, Falcon, and xAI. That's not in most analyst models. If SPCX trades up materially in the first week, the option value of Cursor becomes a real piece of the pricing thesis — and the broader AI-coding-tool consolidation accelerates because SpaceX has the public-market currency to execute.
