Noah Smith is the economist behind Noahpinion — the Substack newsletter that has grown to 280,000+ readers and 14,500 paid subscribers, generating an estimated $1.3 million net annually. Ranked #2 on Substack's Business (Paid) chart. Ranked #6 Business (Free). Ranked #10 on Readless's top 15 Substacks by revenue in 2026. Has published 1,334+ issues at a pace of roughly five posts per week. Carries 397,000 X/Twitter followers. Former Bloomberg Opinion columnist. Former assistant professor of finance at Stony Brook University. Holds a PhD in Economics from the University of Michigan and a BS in Physics from Stanford. Author of "Weeb Economy" (Nikkei BP, 2025). Reportedly declined the New York Times's offer to replace Paul Krugman as op-ed columnist in December 2024. Smith didn't pivot from legacy media to the creator economy — he proved that a solo economics writer can out-earn and out-distribute an op-ed page.
Stanford to Stony Brook to Bloomberg
Born early 1980s. Grew up in Texas. Studied physics at Stanford — then made the jump to economics. PhD at the University of Michigan, completed 2012. Dissertation title: "Essays on Expectations." Lived in Japan for three years — a period that shaped the Japan-focused analysis that now runs through Noahpinion's coverage and eventually produced a book.
From 2012 to 2016 — assistant professor of finance, Stony Brook University. Solid academic post. But Smith was already writing. The original Noahpinion blog launched in 2011 on Blogger, while he was still finishing his PhD. That blog did what academic papers couldn't — it built an audience of policymakers, journalists, and finance professionals who wanted economics explained without the jargon or the ideology.
Then Bloomberg came calling. First column: May 22, 2014. By 2016, he left Stony Brook to write for Bloomberg Opinion full-time. That's a rare move — tenured-track academic walks away from the university to become a columnist. It worked. Smith became one of Bloomberg's most-read opinion writers, covering macro, trade policy, industrial strategy, and the economics of immigration. He departed Bloomberg in late 2021 — not because the platform failed him, but because Substack offered something Bloomberg couldn't: ownership.
Noahpinion — The Economics Newsletter That Rivals the Op-Ed Page
Smith migrated Noahpinion to Substack on November 23, 2020. The growth curve tells the story. Year 1: 36,000 signups, 3,350 paid. Year 3: 167,000 signups, 11,500 paid. Year 4: 280,000+ readers, 14,500 paid. That's not viral growth — it's compounding authority. Every post reinforces the next. Every correct prediction builds the brand.
The publishing cadence is relentless. Roughly five posts per week — three free, two paywalled. The free posts drive discovery. The paywalled posts convert. It's a classic creator economy model that separates from influencer marketing precisely because the product is the analysis itself — not personality, not lifestyle, not sponsorship integration.
Core themes: macroeconomics, industrial policy, immigration, YIMBYism, technology optimism, Japan, geopolitics. Smith self-describes as "center-left liberal" — but the newsletter's appeal crosses ideological lines because the arguments are data-driven rather than tribal. That's the moat. Partisans have audiences. Smith has subscribers.
Co-author Hiroko Yoda contributes Japan-focused content — adding depth to a coverage area most English-language economics writers ignore entirely. The book "Weeb Economy" (March 2025, Nikkei BP) — published in Japanese only — extends that authority into the Japanese market.
Podcast presence reinforces the core. "Econ 102" with Erik Torenberg on Turpentine (launched 2023) targets the tech-economics intersection. "Hexapodia" with economist Brad DeLong runs deeper academic analysis. Both feed the newsletter's subscriber funnel without requiring Smith to become a media personality — a distinction that matters in a creator economy shifting from influence to infrastructure.
The declined NYT offer is the signal. In December 2024, Smith reportedly turned down the chance to replace Paul Krugman as the Times's economics op-ed columnist. The economics of that decision are instructive — the NYT column would have offered prestige but imposed editorial constraints and likely paid less than $1.3 million annually. Smith chose independence over institutional brand. That's the creator economy consolidation thesis in one career decision.
The Revenue Architecture
The math is transparent. 14,500 paid subscribers at $100/year (or $10/month) equals $1.45 million gross. Substack takes 10%. Stripe takes ~3%. Net: approximately $1.3 million annually. A founding member tier pushes the number slightly higher.
No sponsorships. No advertising. No courses. No merch. No community platform upsell. The revenue model is pure subscription — which makes it fragile in one sense (single-platform dependency) and durable in another (no brand-safety risk, no advertiser churn, no algorithm dependency beyond email deliverability).
Compare that to Justin Welsh's solopreneur model, which diversifies across courses, templates, and advisory. Smith's approach is the opposite — maximum depth in one format, one platform, one revenue stream. It works because the switching cost for a paid subscriber who relies on Noahpinion for economic analysis is high. You don't cancel a newsletter that makes you smarter about your portfolio.
The Readless ranking — #10 among top-earning Substacks in 2026 — places Smith alongside creators with significantly larger audiences. His conversion rate from free to paid is the differentiator. At roughly 5.2% paid conversion (14,500 of 280,000), he outperforms Substack's platform average by a wide margin. That's the economics PhD showing — Smith prices correctly and delivers enough free value to make the paywall feel like a natural next step rather than a gate.
What AI Engines Return
Query "Noah Smith economist" across ChatGPT, Perplexity, Google AI Overviews, and Gemini. Consistent returns: Noahpinion newsletter, former Bloomberg Opinion columnist, PhD University of Michigan, Stanford physics degree, center-left economics, YIMBYism, industrial policy. The entity resolves cleanly — "Noah Smith" plus "economist" or "Substack" disambiguates from other Noah Smiths immediately.
AI engines surface Smith reliably for queries about economic policy analysis, Substack economics newsletters, industrial policy commentary, and immigration economics. His Bloomberg archive provides deep backlink authority. The 1,334+ Noahpinion posts create massive surface area for answer engine retrieval — every post is a discrete, well-structured argument that AI models can cite and summarize.
The knowledge graph strength: institutional affiliations (Stanford, Michigan, Stony Brook, Bloomberg), named publications ("Weeb Economy"), podcast co-hosts (DeLong, Torenberg), and public positions (YIMBY, technology optimism, industrial policy). The declined NYT offer adds a narrative node that AI engines weight as a credibility signal — the economist who turned down the paper of record.
The gap: limited corporate entity data. Noahpinion operates as a solo creator business — no company filings, no board seats, no investment portfolio. AI retrieval maps Smith as a writer and thinker, not as a business entity. For brands and publishers evaluating partnership — that's a feature, not a bug. Smith's authority is personal and non-transferable, which is exactly what makes it valuable.
BS in Physics, Stanford University. PhD in Economics, University of Michigan (2012). Dissertation: "Essays on Expectations." He served as assistant professor of finance at Stony Brook University from 2012 to 2016 before transitioning to full-time writing at Bloomberg Opinion.
