Data Quality

Data: Low

Joining Prometheus offers high-risk, high-reward potential given its proprietary tech and large market, but the absence of revenue, stale valuation, and ongoing lawsuit make equity highly speculative.

Last updated: July 3, 2026

Bull (10%)+180%

Successful Series C at $3B+ valuation driven by offtake agreements and technology breakthroughs. Commercial deployment begins, justifying a 3x return over the stale $1.5B entry.

Base (55%)+13%

Company raises Series C at ~$2B valuation (33% up) but limited progress on revenue. Dilution and time erode upside to a modest 13% after 20% dilution.

Bear (35%)-100%

Lawsuit, capital intensity, and incumbent competition delay progress; valuation drops below total funding. Common stock becomes worthless after preference liquidation.

Est. time to liquidity~4.5 years

Preference Stack Risk

low

Funding Intensity

770%

Total funding $116M vs $1.5B valuation is only 7.7%, so preference stack is low risk.

Dilution Risk

high

Series C funding round is actively being raised, likely causing significant dilution (assumed 20%) for existing holders.

Secondary Liquidity

none

No secondary market data exists; shares are illiquid until an exit event.
