Prometheus presents a high-risk, high-reward equity opportunity.

Last updated: March 10, 2026

Bull (30%)+250%

Prometheus leverages its breakthrough e-Kerosene pathway and sub-$50/ton Direct Air Capture (DAC) technology to rapidly scale production, securing major contracts beyond current pre-sales and achieving cost-competitive Sustainable Aviation Fuel (SAF) and diesel without subsidies. This market leadership drives revenue to $500M+ by 2028 and justifies a $5.25B+ valuation (3.5x current) as a clear leader in the e-fuels space.

Base (45%)+75%

Prometheus successfully commercializes its e-fuel technology, capturing a significant share of the rapidly growing SAF market and expanding into other liquid e-fuels. While facing strong competition from established energy players, its proprietary technology allows for steady growth to ~$200M revenue by 2028, leading to an IPO or acquisition at a $2.6B valuation (1.75x current).

Bear (25%)-70%

Scaling challenges, higher-than-expected production costs, or aggressive moves by incumbents like Repsol or Neste erode Prometheus's competitive advantage. Despite initial breakthroughs, market penetration is slower than anticipated, leading to a down round or acquisition at a significantly reduced valuation of $450M (0.3x current), wiping out most common stock value due to liquidation preferences.

Questions to Ask at the Interview

Strategic questions based on Prometheus's data — designed to show you've done your homework.

  • 1

    “Prometheus has announced significant breakthroughs in reducing DAC and e-Kerosene production costs, potentially making Fischer-Tropsch obsolete. How do these advancements specifically translate into a sustainable cost advantage against major incumbents like Neste or Repsol, especially as they also invest heavily in SAF?”

  • 2

    “With a reported ~$12M in revenue and a $1.5B valuation, the company is clearly valued on future potential. What are the key milestones and scaling targets Prometheus aims to achieve in the next 18-24 months to justify this valuation and demonstrate a clear path to profitability?”

  • 3

    “Given the high capital intensity of the e-fuels sector and the Series B funding round in 2021, what is the company's current runway, and what is the anticipated timeline and strategy for future funding rounds or a potential liquidity event for employees?”
