The wealth gap doesn't actually exist on paper—both sit at $15M—but the *revenue generation gap* is striking. Veritasium's physics content attracts a broader, more casual audience willing to watch ads and click sponsors, while 3Blue1Brown's advanced mathematics naturally filters for a smaller, niche demographic. YouTube's algorithm favors watch time and completion rates over educational depth, meaning Derek Muller's explainer format (which breaks complex physics into digestible 10-minute chunks) hits the algorithmic sweet spot harder than Grant's deep-dive mathematics lectures.

Grant's business model is more diversified but paradoxically less scalable. His Patreon at $200K monthly is impressive—it signals superfan monetization—but it's a ceiling business. His educational software and speaking gigs generate prestige and secondary income, but they don't compound like algorithmic reach. Meanwhile, Veritasium's single-channel dominance is actually his strength; Derek optimized ruthlessly for YouTube's ecosystem and let the algorithm work. This is the creator economy's dirty secret: jack-of-all-trades beats master-of-one in total net worth, but master-of-one beats it in annual revenue velocity.

The real wildcard is audience composition. Veritasium's 20M subscribers likely skew younger, global, and mainstream—exactly who advertisers want. 3Blue1Brown's audience skews older, highly educated, and concentrated in wealthy Western markets—premium to Patreon, but smaller in absolute size. Both are financially dominant creators, but they're playing different games: Derek chose viral-friendly physics and won YouTube's lottery, while Grant chose mathematical purity and won the patronage lottery instead.
