Bloom Energy stock surges while analysts question sustainability of gains

Bloom Energy shares have risen around 200% in 2026, and some investors have compared the company to Nvidia. However, analysts say the two companies are very different.

Bloom Energy makes fuel cell systems that produce electricity. Like Nvidia, it has benefited from the growth of artificial intelligence, which needs large amounts of power. Since July of last year, its share price has grown nine times over.

Despite this, analysts at Motley Fool did not include Bloom Energy in their list of top stocks to buy. They pointed to real limits on how much the company can grow. Bloom Energy is also about one hundred times smaller than Nvidia by market value, so a direct comparison is difficult to justify.
