Evidence since late 2021 strongly supports Chamath’s prediction that the creator economy, driven by platforms like TikTok and YouTube, would keep growing and enabling large careers and new content formats:

• Creator economy market growth: Industry estimates put the creator economy at around $100B+ by 2022 and continuing to grow substantially through 2023–2025, with millions of people monetizing content across platforms (YouTube, TikTok, Instagram, Twitch, etc.). These reports describe it as a fast‑growing ecosystem of independent creators earning from ads, sponsorships, fan payments, and more, not a shrinking or stagnant sector.
• Rising creator earnings and careers on YouTube: YouTube has repeatedly reported paying out tens of billions of dollars to creators, artists, and media companies over recent multi‑year windows, and has expanded monetization (e.g., Shorts ad‑revenue sharing, memberships, Super Thanks, etc.), signaling both sustained growth and more viable full‑time creator careers.
• TikTok and short‑form explosion: TikTok’s global user base and watch time have continued to expand since 2021, and the short‑form vertical-video format it popularized has been widely copied (YouTube Shorts, Instagram Reels, Snapchat Spotlight). This has directly enabled many new large‑scale creator careers, especially in niches that didn’t meaningfully exist pre‑TikTok (e.g., certain micro‑influencer, commentary, and short‑skit formats).
• Novel formats and tools: Since 2021 there has been a visible boom in new creator‑centric products and content styles—short‑form vertical video, live shopping, subscription communities, fan platforms (Patreon‑like), and more sophisticated brand‑creator marketplaces—along with widespread coverage describing these as part of a growing “creator economy.”

Chamath’s claim was directional (continued expansion and new creator opportunities, not a specific numeric forecast) and over the "coming years" after 2021. By late 2025, growth in creator earnings, platform investment in monetization tools, and the proliferation of new content formats and full‑time creators on TikTok, YouTube, and similar platforms all align with his prediction, not contradict it. Therefore the prediction is right.
