A newly disclosed stock purchase by Nancy Pelosi's household has sent Bloom Energy jumping, but the company underneath the hype carries real risk for anyone buying in now.

• The trades, filed a month after the fact, included millions of dollars in Bloom Energy and Intel, plus long-dated call options bought near the lows.
• Bloom makes fuel cells that turn natural gas into power, and the AI data center rush has finally pushed the company into solid profits after years of losses.
• The catch is that almost all the money comes from one customer, Oracle, plus a fund Bloom itself part-owns that buys its own products.
• Oracle is piling on debt, and the market is increasingly betting it could struggle to pay — if Oracle pulls back, Bloom's growth story goes with it.
• The stock is already down about 60% from its peak, and fair value estimates land well below where it trades today.

Outlook: Bloom looks more like a short-term momentum trade than a long-term hold unless it lands new customers beyond Oracle and keeps widening its profit margins.
