SpaceX Stock Crashes: The Cursor Deal and Bond Offering Triggered the Drop

SpaceX stock dropped sharply this week, shedding roughly $620 billion in market value over two sessions as the post-IPO rally finally broke. SPCX fell 8.3% combined on June 17 and June 18, closing at $178.50, down from its June 16 peak of $225.64. That's a 20% drop in two days, the first sustained decline since SpaceX went public on June 12 at $135 per share in the largest IPO in history.

This episode breaks down why SpaceX stock is dropping, what triggered the SPCX selloff, and what comes next for the most hyped IPO of 2026. The fall hit despite Moody's, Fitch, and S&P all assigning SpaceX investment-grade credit ratings on the same Thursday the stock dropped nearly 4%. The paradox is the story.

Four triggers drove the SpaceX stock drop. First, the $60 billion all-stock acquisition of Cursor, announced June 16, signaled immediate dilution to anyone who bought SPCX on the open market. Second, a planned $20 billion bond offering raised an obvious question after SpaceX had just pulled in $75 billion from the IPO and committed $60 billion to Cursor: how much capital does this company actually need? Third, SPCX options started trading on June 17, giving short sellers a practical way to bet against the stock for the first time. Nearly 1 million call contracts traded on day one, putting SPCX among the busiest options names on Wall Street. Fourth, the fundamentals caught up. SpaceX posted a $4.28 billion net loss in Q1 2026, wider than the $528 million loss in the year-ago quarter, with xAI alone accounting for $2.5 billion of the operating charge.

The float math is part of the volatility story. Only 4-5% of SpaceX shares are in the public float. Roughly 95% are locked up at IPO. Selling windows open in late July 2026, the standard lockup lapses in December 2026, and Musk's stake unlocks in June 2027. With limited liquidity, small flows move the SPCX stock price hard in both directions. The Gary Black "meme stock" critique landed because retail investors bought roughly the same amount of SPCX in three sessions as they bought Nvidia, Google, Amazon, Microsoft, Meta, QQQ, and SPY combined, according to Vanda Research.

The broader picture matters for SPCX shareholders. SpaceX still trades at a $2.4 trillion market cap, the sixth-largest US company by value. The stock ended its first week as a public company 37% above its IPO price. But the xAI subsidiary that justifies a chunk of the trillion-dollar valuation is bleeding cash: $6.36 billion in 2025 operating losses on $12.7 billion in capex, and every one of xAI's 11 original co-founders had departed before the IPO. Musk himself said publicly in March 2026 that xAI "was not built right first time around."

We also cover the other space-sector moves this week. Planet Labs (PL) dropped sharply after an earnings report showed margin pressure and near-term losses despite a record backlog, raising questions about whether satellite-data businesses can scale profitably. Intuitive Machines (LUNR) expanded its NASA partnership and shifted toward recurring lunar infrastructure revenue, a model that could de-risk a sector full of one-shot government contracts.

We cover what the SpaceX stock drop means for retail SPCX holders, why the Cursor acquisition and bond offering hit confidence on the same week, what the lockup calendar through 2027 means for sustained selling pressure, and whether the post-IPO selloff is a healthy reset or the start of a bigger correction.
