SpaceX shares traded at $129 on secondary markets shortly after 1 p.m. EDT Thursday, an 11.7% single-session gain that pushed Elon Musk's net worth back above $800 billion for the first time since mid-July. The move reverses three weeks of drift in which SpaceX paper traded between $112 and $118, a range that had dulled allocator enthusiasm following the company's last tender offer in May at $115.
The spike occurred without announced news from SpaceX, suggesting either a large block crossed on Forge or EquityZen, or a cluster of buy orders from family offices updating exposure after Q2 portfolio reviews. Volume data on secondary platforms remains opaque, but the $129 print represents a 12.2% premium to the May tender price and implies a fully diluted valuation near $215 billion, depending on option-pool assumptions. Musk's stake—roughly 42% including performance-based awards—thus moves from $48 billion to nearly $90 billion in SpaceX equity alone, the swing that carries his consolidated net worth past the $800 billion threshold when combined with Tesla holdings and xAI's recent $50 billion private round.
The timing matters because SpaceX is expected to launch its next tender offer in late September or early October, a semi-annual liquidity event that has become the primary price-discovery mechanism for the company's equity. If secondary markets hold near $129 through August, the tender could clear at $125 to $130, a level that would price new capital at a 16% to 19% premium over the spring round and likely draw fresh allocations from sovereign wealth funds that passed in May. The company's Starship program logged 18 test flights in the first seven months of 2026, double the cadence of 2025, and NASA's Artemis III contract now schedules a manned lunar landing for Q1 2027, both milestones that justify valuation expansion in the eyes of long-duration allocators.
Operators should watch for confirmation of the $129 print across multiple platforms by Friday's close, and whether SpaceX insiders or early employees are net sellers into the rally, a pattern that has preceded prior corrections. Family offices with SpaceX exposure above 3% of NAV may face valuation-reporting questions if the spike persists, since auditors typically require two independent quotes for illiquid positions. The next Starlink revenue disclosure—expected with SpaceX's Q2 2026 unaudited summary in mid-September—will clarify whether the unit's rumored $8.7 billion annualized run rate justifies the move or whether this is a technical squeeze in thin secondary volume.
Musk's return above $800 billion resets the wealth-ranking optics but does not alter his liquidity profile: fewer than 2% of his SpaceX shares are pledged or readily saleable, and Tesla's stock has traded flat since June. The $129 print is the signal; the September tender is the event.
The takeaway
SpaceX secondary shares spiked 11.7% to $129, the highest in three weeks, ahead of a likely September tender that could set a new floor.

Your next customer won't visit your website. Their AI will.
AI assistants have quietly taken over the first step of buying — they answer from catalogs they can read and shortlist whoever can actually ship. Two questions now decide whether you exist to that buyer: can a machine read your catalog, and can you fulfill the order. Most brands fail one or both and never find out why the orders went elsewhere. The winners of this shift aren't the loudest. They're the most readable. Build for the machine that's about to do the shopping.
