SpaceX’s $25 billion bond, upsized from an initial $20 billion target on the back of strong institutional demand, has drawn a bubble warning from Allianz Chief Investment Officer Ludovic Subran, as the company’s stock continues to trade more than 30% below its post-IPO high of $225.64.
The offering’s structure, disclosed in a SEC pricing document, spans five tranches of senior unsecured notes: $7.0 billion of 5.350% notes due 2031, $6.0 billion of 5.650% notes due 2033, $6.0 billion of 5.875% notes due 2036, $2.5 billion of 6.600% notes due 2046, and $3.5 billion of 6.650% notes due 2056. The five tranches sum to exactly $25 billion and are expected to settle on 26 June 2026, subject to customary closing conditions.
The notes are being offered exclusively to qualified institutional buyers under Rule 144A and to non-US persons under Regulation S, and have not been registered under the Securities Act. According to the SEC filing, SpaceX intends to use net proceeds to repay its outstanding bridge loan facility in full, cover related fees and expenses, and direct any remainder to general corporate purposes.
SpaceX $25 Billion Bond Draws Bubble Warning from Allianz
According to the Financial Times, Allianz CIO Ludovic Subran argued the enlarged debt offering is consistent with companies exploiting elevated equity prices and favourable borrowing conditions to raise capital at pace. Subran drew a distinction between equity investors focused on long-term growth and debt investors who typically want predictable income and stable returns, a tension the offering’s coupon structure makes visible, with the longest-dated 2056 tranche priced at 6.650%.
The speed of SpaceX’s return to the capital markets is what Subran found telling. The company’s S-1 was filed on 20 May 2026, and its IPO took place on 12 June 2026 at the Nasdaq MarketSite in New York. The bond offering followed within weeks. Yahoo Finance reports the offering was originally sized at $20 billion before demand prompted SpaceX to upsize it by $5 billion.
Short Interest Climbs as SPCX Slips Below Debut Price
The stock was trading near $151 at the time of writing, down roughly 2% on the session and approximately 21% lower over five trading days. SPCX has not recovered from the sharp retreat following its post-listing rally, which peaked at $225.64.
Wealth Professional, citing Ortex data, reports that short interest has climbed to 13% of the public float, up from 8% in the prior session, representing approximately 83 million shares against an average daily volume of approximately 270 million shares. Ortex co-founder Peter Hillerberg flagged that such a concentrated short build-up in a newly listed company is unusual, and noted that a rush to cover could trigger a squeeze. He also told Reuters that SPCX trades at roughly 141 times 2025 revenue, against a valuation of approximately $2 trillion.
Ortex tied the selling pressure to profit-taking in recently listed names and a broader pullback in risk-sensitive assets as investors reassess the stock’s early-stage premium.
Analyst Coverage Frames the Valuation Debate
Susquehanna analyst Charles Minervino initiated coverage with a Neutral rating and a $170 price target, according to Sahm Capital. The $170 target sits above the $150 debut price but well below the post-IPO peak. CoinGape reports that Susquehanna’s model assumes SpaceX grows revenue at an 81% CAGR and adjusted EBITDA at a 76% CAGR between 2025 and 2028. The brokerage also cautioned that several of SpaceX’s business lines operate in markets that remain relatively untested, and that the current valuation depends on aggressive growth assumptions and premium multiples.
KeyBanc initiated with a Sector Weight rating and no price target, acknowledging SpaceX’s dominant position in commercial launch while concluding that the long-term upside is already reflected in the share price. Crypto.news notes that both initiations arrived with the stock trading below its $150 debut price.
Separately, unconfirmed reports via TD Cowen raised the possibility of SpaceX pursuing an acquisition of T-Mobile if a network-sharing agreement with the carrier fails to materialise. Both companies have declined to confirm anything, and the scenario remains speculative.
The binary question for SPCX from here is whether the 13% short interest becomes a catalyst for a squeeze as the stock approaches the debut price, or whether the debt load added by the $25 billion offering and the 141x revenue multiple keep institutional sellers in control.
