⚡ Short nuclear: SMRs miss the economic window
By the time large reactors (2032-35) or SMRs clear permitting, solar+storage will have driven marginal electricity cost toward zero — nuclear 'does not hang together mathematically.' Disclosed position: 'Massively short nuclear.'

IS THIS A TRADE?
🚫 Not a trade — conviction 9.5 is DORMANT, below WATCH (45) and far from the GREEN entry bar (65). If more weighted voices pile on, it climbs; two mentions isn't conviction.
direction semantics: bearish = the plays below are expected to FALL if the thesis is right → expression is short / puts.

“Massively short nuclear... they've missed the window. By the time they deliver working SMRs at scale, the marginal cost of electricity will effectively be zero because of solar and storage... large form factor nuclear reactors make zero economic sense by 2032 or 2035... it just does not hang together mathematically.”

“that's if you assume no shift in the demand curve. ... going to 8 terawatts of production by 2040 ... I really do question whether we can pin everything on solar. ... at some point here, there's an inflection that we have to meet.”

SUPPORT
“by the time any of these SMRs actually get near production, the TCO of solar will be like $10 or $12 per megawatt hour, and it will be 80% of all the power generation. It'll make no sense by the time SMRs get online. ... That reactor won't even get turned on until 2030 The entire world will be covered by solar by then, so it won't matter.”
