SpaceX shares declined again Thursday after the company announced a $25 billion bond offering, according to Yahoo Finance. The debt sale comes as Elon Musk's rocket venture faces renewed scrutiny over its valuation and growth trajectory. Investors are parsing whether the move signals a liquidity need or strategic repositioning.

The bond offering arrives amid a swirl of speculation about a potential merger between SpaceX and Tesla. Inc. reports that financial timing and stock dynamics could make a deal possible within the next 60 days, a scenario that Musk has not publicly confirmed. If realized, the combination would create an entity unlike any other in corporate history.

SpaceX's CEO has previously claimed the company could one day account for 88% of U.S. GDP, though he offered no timeline for that projection, according to Motley Fool. Meanwhile, Musk has reportedly lost his trillionaire status as SpaceX stock has fallen, Yahoo Finance reported earlier Thursday. The conflicting signals highlight the volatility surrounding the firm.

The $25 billion bond deal is one of the largest ever from a private company, and its success will test investor appetite for high-risk aerospace debt. If the merger with Tesla materializes, it would concentrate enormous power in Musk's hands. A separate Yahoo Finance analysis predicted that a $1,000 investment in SpaceX stock could be worth significantly more by September, though the forecast depends on market conditions.

Critics warn that Musk's vision of SpaceX dominating the U.S. economy is unrealistic and potentially dangerous, given the company's current challenges and regulatory hurdles.
