Oklo Inc. OKLO
Oklo is a $3bn pre-revenue SPAC nuclear story whose 5x-lowballed fuel costs, unrealistic 2027 NRC timeline, and inexperienced 'Nuclear Bros' management mean shares should collapse as reality intrudes.
Thesis
Kerrisdale is short Oklo Inc., a $3bn pre-revenue nuclear SPAC promising 15-50 MWe sodium-cooled microreactors it calls 'powerhouses.' The thesis rests on four pillars. First, Oklo's $7,000/kg HALEU fuel cost assumption — the foundation of its 'illustrative' $40-90/MWh LCOE — is lowballed by ~5x versus the $30,000-40,000/kg industry experts cite, rendering its unit economics 'completely made up' per a former NRC Commissioner. Second, regulatory approval will take at least 4 years; the company's 2027 first-deployment target is 'beyond optimistic' after its 2022 license application was denied. Third, sodium-cooled fast reactors have a documented history of fires, leaks and shutdowns (Monju, Superphénix). Fourth, Citi estimates $2.7bn of additional capital is required, making a dilutive raise inevitable after the parabolic, retail-driven 300% rally. Street price targets near $10 imply ~55% downside.
SCQA
Oklo is a $3bn pre-revenue nuclear company that came public via Sam Altman's AltC SPAC in May 2024, aiming to design, build, own and operate small sodium-cooled microreactors marketed to AI data centers.
Its 'illustrative' unit economics rest on a $7,000/kg HALEU fuel assumption that is 5x below reality, NRC approval is at least 4 years away, and management — described as 'Nuclear Bros' — has zero commercial nuclear operating experience.
Investors should sell or short the stock, recognising that the recent 300% retail-driven rally and Chris Wright Energy Secretary nomination do not change Oklo's fundamental commercialization, capital and regulatory headwinds.
Street price targets near $10 versus the $22 share price imply roughly 55% downside; further dilution from a $2.7bn capital raise and approaching lock-up expiry compound the asymmetric short setup.
The three reasons
- 1
Oklo's $7,000/kg HALEU fuel cost assumption is lowballed by 5x
- 2
NRC license at least 4 years away; 2027 deployment 'beyond optimistic'
- 3
$2.7bn additional capital required; dilutive raise highly likely
Primary demands
- Sell or short OKLO shares
- Reject Oklo's illustrative unit economics as not credible
- Discount management's regulatory and deployment timelines

Notes
Classic Kerrisdale long-form short report: text-heavy prose with embedded charts, expert-interview quotes (former NRC Commissioner, former Oklo employee, Westinghouse fuel veteran) used as primary evidence. Memorable rhetorical devices: 'Nuclear Bros' framing, 'Fission Impossible' subtitle, repeated use of italicized expert quotes ('completely made up from their rear end', 'they were goal-seeking costs'). Strong CFO Cochran quote-contradiction on '50 MWe' modularity vs prior 'strategically small' positioning. Notable charts: SMR cost-escalation peer comparison (p.10), 500MW vs 10x50MW reactor visualization (p.11), Morgan Stanley SMR data-center share projection (p.18). Sam Altman / AltC SPAC backstory in Appendix II is meaningful context. No author signature — institutional Kerrisdale byline only. Stake size not disclosed beyond 'short shares'.
