Available data show that the total cryptocurrency market capitalization:

• Was around $2–3 trillion in late 2021 and briefly hit about $3 trillion in November 2021, consistent with the context of Chamath’s comment. (fortune.com)
• Reached new all‑time highs in 2024–2025, with reports of the total crypto market cap around $3.8T in July 2025 and roughly $4T in Q3 2025, surpassing the prior ~$3T peak from 2021. (cointelegraph.com)
• Was about $4.21T when Bitcoin hit an all‑time high above $125,000 in October 2025, and around $3.5T in mid‑November 2025 during a consolidation phase. (investopedia.com)

There is no evidence that the global crypto market cap has reached $6 trillion, let alone $10 trillion, by November 30, 2025; the documented highs are in the ~$4T range. (cryptorank.io)

However, Chamath’s prediction as phrased (“will grow over time to roughly $6 trillion and then to roughly $10 trillion”) does not include a clear time horizon. Since crypto market cap has grown beyond the ~$3T level he referenced but has not yet had enough time (or a specified deadline) to definitively prove or disprove eventual moves to $6T and $10T, the claim cannot be judged fully right or wrong as of 2025.

Because the numerical targets have not been reached but the prediction had no explicit time limit, the fairest assessment today is: too early to tell → inconclusive.
