From the ACX 2025 Prediction Contest:

I will resolve according to the Metaculus resolution:

This question resolves as Yes if, according to the Bloomberg Billionaires Index, Elon Musk is ranked #1 in net worth when the resolution source is accessed by Metaculus on December 31, 2025. If Musk is not ranked #1, then this question resolves as No.

Elon owns 42% of SpaceX, which already adds $160 billion.

@TimothyJohnson5c16 from what I understand the Forbes list (and maybe Bloomberg too?) already accounted for a valuation of xAI and SpaceX, but I may be wrong. In any case I doubt we should add $160bn to his wealth. The valuation was not zero before yesterday.

@MachiNi this matches my understanding, with the caveat that private assets are only valued sporadically. So it might be the case that a jump (positive or negative) is to be expected if e.g. SpaceX's valuation has changed a lot in the last 6-12 months.

@MachiNi Oh, yeah, I didn't mean to imply all of this is new. The previous valuation I saw several months ago was $350 billion.

Elon has lost a lot recently, but so has everyone else:

bought Ṁ250 NO

Buffett Boys rise up!!

The sweepstakes market for this question has been resolved to partial as we are shutting down sweepstakes. Please read the full announcement here. The mana market will continue as usual.

Only markets closing before March 3rd will be left open for trading and will be resolved as usual.

Users will be able to cashout or donate their entire sweepcash balance, regardless of whether it has been won in a sweepstakes or not, by March 28th (for amounts above our minimum threshold of $25).

opened a Ṁ5,000 NO at 72% order

jim order up

filled a Ṁ4,000 YES at 82% order

@jim Thanks, I took most of it

@TimothyJohnson5c16 u realise this is just the start

@jim Maybe, but even if TSLA drops 50%, Elon will still be ahead.

@TimothyJohnson5c16 frankly I think this is looking bad for me. My thesis was that Elon's wealth would stagnate and others' would rise sharply. But if xAI keeps crushing then that won't happen

@jim I need to think about it more carefully TBH, rather than going off of vibes. But I did some forecasting last night about AI revenues at EOY and arrived at very big numbers.

@jim Hmmm, I still think it will take longer before AI starts generating lots of revenue. Stock valuations could go crazy anyway based on expectations, but I think they're already kind of crazy now 🤔

@TimothyJohnson5c16 they're crazy now, how crazy will they be EOY when AI companies are raking in 100+ billion in revenue from coding agents

@jim Want to bet on that? I'm pretty sure that the total revenue in 2025 for all AI startups combined will be under $100 billion.
