IBM shares plunge 25% in historic single-day crash

IBM shares have experienced a historic single-day decline, falling by just over $73 to settle at approximately $217. This represents a 25% drop in share price, a move described by CNBC as a significant market event that has established conditions for a unique options strategy.

The magnitude of the fall has drawn attention from investors, although the specific catalyst for the decline is not detailed in the source material. The historic nature of the drop has set up a distinct trading environment, with the source noting that the crash has created conditions for a unique options strategy for those looking to navigate the volatility.

While the IBM event dominates the immediate narrative, broader market sentiment has been influenced by other major developments. Concurrently, US equity markets saw modest gains coinciding with the debut of SpaceX shares on the Nasdaq and reports regarding an interim peace deal between the United States and Iran, which contributed to a drop in oil prices.

SpaceX opened trading on the Nasdaq on 11 June 2026 at $150 per share, following a record-breaking initial public offering priced at $135. The company raised approximately $75 billion, valuing it at around $1.77 trillion. On its debut day, the stock rose 27% to $172.

However, the momentum for the spaceflight manufacturer has since shifted. SpaceX shares have fallen below their initial public offering price of $135 for the first time, marking the fourth consecutive session of losses. This decline occurred shortly after the company’s recent entry into the Nasdaq-100 index.

The juxtaposition of these events highlights the divergent paths within the market. While IBM’s sharp correction has created specific opportunities for options traders, the broader context includes the cooling of enthusiasm for SpaceX and stabilising oil prices due to diplomatic developments.
