PLUG Power Call Buyers See Fast Returns

Upside option positions are delivering exceptional profits in Plug Power Inc (PLUG).

On September 18, 2025, Market Rebellion’s Unusual Option Activity Service identified massive bullish call buying, with 53,000 17October 2.50 calls bought above the existing open interest of 2,742 contracts, with PLUG shares trading at $2.04-$2.05.

Those 17October 2.50 calls traded as high as $0.89 today with the stock at $3.15, delivering impressive returns of approximately 585% to 642% from the initial entry price range of $0.12 to $0.13. Meanwhile, PLUG shares gained approximately 54% from their initial trading level around $2.04, demonstrating how options can deliver significantly amplified returns compared to simply owning the underlying stock.

This performance illustrates the power of options leverage when the directional thesis proves correct, though it’s important to note that this same leverage can work against traders when market moves go in the opposite direction.

SEC Filing and Operational Milestones Drive Momentum

The primary catalysts driving PLUG’s explosive move came after the unusual options activity, starting with the company’s September 22, 2025 filing of a prospectus supplement with the U.S. Securities and Exchange Commission. The document covers the resale of common stock related to warrants issued in March 2025, representing over 185 million shares at a $2.00 exercise price that remain valid until March 2028. This regulatory filing provided clarity on the company’s share structure and addressed potential investor concerns about dilution.

Additional momentum built as Plug highlighted continued operational progress and hosted institutional stakeholders as part of a broader transparency push. The timing of these developments, occurring just days after the unusual call buying activity, created the perfect setup for options traders who had positioned for upside in the October contracts.

Record Production Numbers Showcase Scalability

Key operational validation came from the company’s September 23, 2025 announcement that its Georgia green hydrogen production plant achieved record-setting performance in August, producing 324 metric tons of hydrogen with 97% uptime and 99.7% availability. These impressive figures underscore the scalability of Plug’s GenEco electrolyzer technology and strengthen its position as a leader in large-scale hydrogen production.

The company actively courted institutional stakeholders through an investor tour at the Georgia facility hosted with Oppenheimer on September 23rd, with management including Chief Revenue Officer Jose Luis Crespo and VP of Investor Relations Roberto Friedlander communicating the strategic vision. The combination of strong operational metrics and increased transparency helped build confidence in execution capabilities, amplifying the stock’s momentum and rewarding those positioned in the October call options.

PLUG closed the session at $2.53, down 4.65% on the day.
