By and large no. Read the comments under anything on LessWrong, for example, and it’s trivial to pick out the vast majority of nominally substantive posts lighting on the one thing that got them mad, just like you and I, in amidst a chorus of nothing remarks equivalent to “so brave, so powerful”. They’re just people man, after all.
Notice that the disagreements people get into by and large evolve the same way as reddit fights - everybody’s just waiting for their turn to nitpick some sentence or other that (nominally) deserves a fair, contextual, interpretation it’ll never receive.
I would be really really really surprised if, on average, LWers (et al.) performed better or worse than the average schmuck who decided to take a punt on proper investing or running a business or whathaveyou.
Beating the market is extremely hard. Riding the market is unbelievably easy, and gets easier constantly. Running a successful business is nearly impossible and gets harder all the time.
For these reasons most people don’t bother, take a job in somebody else’s company, and sometimes invest their savings in something very broad and shallow and safe like an index fund.
On the other hand, rationalism is an extremely well-funded cult, so it’s top-heavy with unbelievably bad decisions made with infinite thielbucks.

Probably you can find a fair few good stories which are couched as “donations” because, again, rationalism is a cult, and investments in a business are framed in terms of “donations”, or tithes, to this or that cause within the movement. It may not offer a concrete return to the tither, but as with a tithe they do actually expect to get something in return.
If Scott Siskind Alexander very publicly kicks a few bucks to Max More’s cryonics scheme every now and then alongside human enhancement research to preserve a future for our white children, and makes sure he’s picked the RIGHT AI alignment protocol, he isn’t a neutral third party to the future those decisions are helping design.
The whole architecture of the group is a speculative ponzi scheme projected far off enough into the future that nobody can complain when their abstract ideas of expected return fail to come good after all.
Indeed on another level looking for good stories about bad investments is a bit of a contradiction in the sense that what you’re looking at to begin with is, for whatever else turns up in the ‘TESCREAL’ acronym, primarily a scam dreamed up by Eliezer Yudkowsky back in the early 2000s no different from scientology and L. Ron Hubbard.
