Chamath’s prediction was that MrBeast (Jimmy Donaldson) would become a “multi multi‑billionaire”, i.e., have a net worth in the multiple billions of USD (well above $2B).

What we can see today:

• Multiple outlets now report MrBeast as a billionaire, with net‑worth estimates around $1 billion, based largely on Celebrity Net Worth’s figure.(celebritynetworth.com)
• MrBeast himself has publicly confirmed that he is a billionaire “on paper” in a 2025 appearance on Steven Bartlett’s Diary of a CEO podcast.(hypebeast.com)
• Separate reporting on his business, Beast Industries, indicates that recent funding rounds value the company at about $5 billion, and in a 2024 deposition he stated he owns “a little over half” of it, implying an equity stake above $2.5B on paper.(businessinsider.com)
• Some analyses therefore frame his wealth as roughly $1B under conservative assumptions, but $2.5–3B+ if you fully mark his private equity stake to the latest $5B valuation.(thetrademedia.com)

Because:

1. There is no consensus: widely cited “net worth” sites and mainstream coverage still describe him as roughly a $1B billionaire, while business/valuation–based analyses plausibly put his stake above $2.5B on paper.
2. His company is private, so we cannot independently verify whether those $5B valuations (and the implied $2.5B+ stake) should be fully counted as personal net worth today.
3. The original prediction had no time horizon, so we are not yet in a position to say he failed to become multi‑billionaire either.

Given these conflicting estimates and definitional issues around how to compute his “net worth” (cash vs. illiquid private equity vs. conservative vs. aggressive valuation), it cannot be determined with confidence whether he is already a multi‑billionaire, even though it is clearly plausible on paper. Hence the outcome of the prediction is ambiguous, not cleanly right or wrong at this time.
