Druckenmiller rotated out of SanDisk after pocketing a 400% gain in a single quarter. The move wasn’t a retreat from AI — it was a pivot within it.
He sold 166,235 SanDisk shares through his Duquesne Family Office. SanDisk had been a clean trade. The stock was spun off from Western Digital in February 2025, right as AI-driven demand for NAND flash memory was accelerating. Hyperscalers building out training clusters needed storage. SanDisk supplied it. The stock ran hard.
But a 400% gain in one quarter prices in a lot. Memory chips are cyclical. Druckenmiller appeared to decide the easy money was made.
His replacement trade was Bloom Energy, a company that makes solid-oxide fuel cells that convert natural gas into electricity. The stock has risen more than 800% since its 2018 IPO.

The logic is straightforward. AI data centers need enormous amounts of power. The five largest AI hyperscalers have outlined up to $720 billion in capital expenditures for 2026, much of it for new data center capacity. Grid connections involve multi-year permitting timelines. That’s a real bottleneck.
Bloom Energy’s fuel cells can be installed behind the meter, bypassing the grid entirely. That gives data center developers a way to get firm, dispatchable power without waiting years for grid approval.
The company already has deals in place with Oracle, CoreWeave, and Equinix to deploy its systems at new data center campuses.
Bloom Energy’s Q1 2026 results landed on April 28 and were hard to ignore. Revenue came in at $751.1 million, up 130% year-over-year, well above the $531.3 million analyst consensus. EPS hit $0.44, against an estimate of $0.09.
Management raised full-year 2026 guidance to $1.85–$2.25 EPS, citing surging data center demand and the Oracle partnership as key drivers.
Analyst upgrades followed quickly. BTIG raised its target to $295 with a buy rating. RBC moved to $335 with an outperform. UBS set a $251 target with a buy. The stock’s average analyst rating sits at “Moderate Buy,” though the average price target of $194.95 now sits well below where the stock is trading.
Vanguard also added to its position, buying an additional 45,557 shares in Q4, bringing its total stake to 20.85 million shares, about 8.82% of the company, valued at roughly $1.81 billion.
Goldman Sachs raised its Bloom Energy position by 50.3% in Q1, adding 836,810 shares.
Not everyone is bullish. JPMorgan’s target sits at $267, TD Cowen at $235, Wells Fargo at $217 — all below the current price. Some analysts have flagged stretched forward multiples as a risk if growth or margins disappoint.
Insider activity adds another wrinkle. Over the last 90 days, insiders sold 455,092 shares worth approximately $78.6 million.
Bloom Energy opened at $287.41 on Thursday, near its 52-week high of $290.50.
