How it compares to the market

Benchmarked against 2049 companies in Other Energy. Each bar is a median (the middle company, not an average — outliers don't skew it). Two yardsticks: real money raised (reported on Form D) and modeled value (our estimate est.). These are whole-sector medians across all stages, except the per-stage row.

Total raised — vs sector median (real $, all stages) 267× above median
This company$915.7M
Sector median$3.4M
Latest round — vs other Growth/Late rounds in sector (real $, this stage) 0.9× of median
This company$452.0M

Modeled value — vs sector median (estimate, all stages) 236× above median
This company$4.0B
Sector median$17.0M

Raised more than 100% of sector peers (real $). Modeled value above 99% of peers (estimate).

Niche peers — same stage & era

A tighter cohort than the sector chart above — only companies at the same stage (Growth/Late) that last raised in the same ~3-year era, ranked by modeled value est. (not money raised). This is the exact set the analyst read compares against, so a like-for-like cohort is what makes "over/under-valued" meaningful.

Not enough valued peers in this cohort to chart positioning.
