The Age of Extraction is the label Columbia Law School professor Tim Wu gives to the current phase of the digital economy, in which the largest platforms earn more by charging for access to the markets they control than by improving what they offer. The phrase comes from his book The Age of Extraction: How Tech Platforms Conquered the Economy and Threaten Our Future Prosperity, published by Knopf on November 4, 2025. Wu condensed the problem in a Lawfare interview published eight days later: "too much extraction by an essential infrastructure". The term names a period rather than a practice. Its working parts, however - take rates, placement fees, self-preferencing - are line items for any business buying media on Amazon, Google or Apple.

How extraction works

Wu describes a two-stage life cycle. In an enablement phase a platform competes by being useful: cheap to join, open to sellers, better than rivals. Once it has "established a monopoly on both sides of the market", as he put it to Lawfare, it enters an extraction phase and raises its charges. "The first half of their life was building a better product. The second half of their life has been extraction," he said.

The economics are conventional. Wu said he borrowed the idea from microeconomics, where extraction means monopoly rent: what a firm can charge because no competitor or "something else" is disciplining it. A fee is not extractive because it is large. On this test it becomes extractive when nothing stops it rising.

A platform sits between buyer and seller and can charge both. Amazon is the book's central case. Its Marketplace levies a referral fee, akin to a commission, of 15% on most products, then fulfilment and storage fees and, increasingly, advertising, according to the Institute for Local Self-Reliance (ILSR), an anti-monopoly research group. Wu called "the placement fee - they called it advertising - the sponsored result" Amazon's "master stroke". On every $100 of seller revenue, ILSR estimated Amazon's combined cut at $19 in 2014, $34 in 2021 and $45 in the first half of 2023.

Advertising is where the mechanism turns technical. A 2023 working paper by Tim O'Reilly, Ilan Strauss and Mariana Mazzucato at University College London set out a theory of algorithmic attention rents: whoever controls ranking can move shoppers' attention from the most relevant organic results to paid ones. Their Amazon study found that an ad lifted a product the platform's own algorithm ranked lower by a median of 17 positions. "For the most part Amazon's ad business appears simply to be an additional fee levied on merchants rather than providing added value to them," the authors wrote.

A trilogy and a movement

The book closes what Wu calls a trilogy. The Master Switch (2010) traced how information industries open, consolidate and stagnate, and The Attention Merchants (2016) followed the trade in human attention. Wu, who coined "network neutrality", advised the Federal Trade Commission (FTC) from 2011 to 2013 and the White House on technology and competition policy from 2021 to 2023, according to his Columbia curriculum vitae.

He began, he said, with a single sentence: "Everything has to happen somewhere." Platforms in the book descend from the market square, and whoever writes the rules of that square shapes the society around it.

The argument then widens. According to a Washington Monthly review by Kainoa Lowman, Wu sets out a "sequence in five steps" - monopolisation, extraction, mass resentment, democratic failure and the rise of the strongman - which he calls "the real road to serfdom", a play on Friedrich Hayek. Later chapters extend "platform power beyond tech" to medical practices and rental housing. His remedy is an "architecture of equality": antitrust enforcement, utility-style regulation and price caps, common carrier and neutrality duties, structural separation so platforms stop selling on their own marketplaces, and limits on carrying dominance into new markets such as artificial intelligence (AI).

Cory Doctorow, a childhood schoolmate of Wu's, formalised "enshittification" in a November 2022 blog post and published a book of that name on October 7, 2025, four weeks before Wu's. ILSR had been calling Amazon a "monopoly tollbooth" since July 2020.

Why advertisers and publishers pay attention

Amazon's advertising business took in $56 billion in 2024 and $68.6 billion in 2025, and second-quarter 2026 revenue rose 26% to $19.8 billion. Its largest contributor is Sponsored Products, the format Wu calls a placement fee; the FTC's antitrust suit of September 26, 2023 alleges that Amazon replaced relevant organic results with paid ones. A separate complaint filed by the FTC and 22 states on August 31, 2026 alleges about $20 billion of undisclosed surcharges, with the share of clicks billed at the advertiser's full bid rising from 4% in late 2020 to 79.1% in 2024. A 3.5% surcharge on fulfilment fees followed on April 17, 2026.

On the open web the equivalent figure is the take rate, the share of spend an intermediary keeps. A Virginia court found in April 2025 that Google had monopolised the publisher ad server and ad exchange markets, and the later remedies opinion records that its AdX exchange charged 20% where rivals charged closer to 10%. App developers paid Apple up to 30% until a judge barred commissions on purchases made outside apps on April 30, 2025; an appeals court on December 11, 2025 gave Apple a chance to claim a reasonable commission on those sales, according to Reuters. Publishers meet a newer variant in AI. Cloudflare data from July 2026 put crawl-to-referral ratios at between 118 and nearly 50,000 crawls per referred visit across AI operators.

Where the argument is contested

Evidence is the first objection. Lowman wrote that Wu presents the five-step sequence as "a sort of natural law" with little empirical support, and that the book leaves out examples an advertising reader would expect, including Google's ad tech fees and Apple's in-app commission. Jennifer Szalai, reviewing for The New York Times, called it "an intelligent and useful guide to a dispiriting present" but found the remedies "old-fashioned and straightforward".

The line between a fee and extraction is the second. Alan Rozenshtein, Lawfare's research director, called it "the key conceptual hinge" of the book and suggested that claims of platform decay can be "a little vibes-based". Wu answered with a structural test rather than a price test: a monopoly held for 15 years with little sign of improvement and a record of destroying competitors.

The third is that the remedies pull in opposite directions, according to Kate Klonick of St. John's University, who argued that treating platforms as utilities "is the opposite of an antitrust solution". Wu replied: "I reject the idea that they're opposites."

Consumer benefit is the fourth objection. A review on onStrategy argued that the book underplays the surplus that near-free search, maps and logistics created before any extraction began. Courts have also rejected parts of the monopoly premise. On November 18, 2025 Judge James Boasberg dismissed the FTC's case against Meta, finding that TikTok and YouTube compete with Facebook and Instagram; Wu had described Facebook as a company that "doesn't really have to do anything" to keep its users. Amazon disputes the harm too. Answering the pricing complaint, it said inflation-adjusted cost per click for Sponsored Products was flat from 2019 to 2024 while conversion rates rose more than 24%.

The numbers do not agree. ILSR put Amazon's share of seller revenue at 45% in the first half of 2023, Marketplace Pulse figures reported by Fortune put it at around 50% in 2022, and Lowman relays Wu's figure of more than 50% by 2023. The methods differ on whether advertising counts as a fee at all, which is the question in dispute.

Not the same as

Enshittification. Doctorow's term describes a decline in quality: platforms serve users, then degrade the service to favour business customers, then squeeze both. Extraction describes where the money flows. Wu has endorsed the diagnosis while calling the word Doctorow's.

Surveillance capitalism. Shoshana Zuboff's framing, from her 2019 book The Age of Surveillance Capitalism, centres on behavioural data and prediction. Wu centres on fees and market structure, with data one resource among money, time and attention.

Take rate. A measurable share of spend retained by an intermediary. Calling it extraction is a claim that the rate exceeds what competition would allow.

Resource extraction. The phrase predates Wu in environmental writing, as in Brian Czech's 2013 essay "The End of the Age of Extraction" on natural resources. It has nothing to do with platforms.

Recent developments

Regulators have so far changed the rules rather than the owners, the opposite of Wu's structural preference. On September 2, 2026 Judge Leonie Brinkema rejected every structural remedy sought against Google's ad tech business, leaving AdX and its fee in Google's hands under six years of conduct rules; a jointly proposed final judgment is due on October 2, 2026. Digital Content Next, the publisher trade body, set the outcome against financial exchanges, where the same conflict is prohibited by statute. In August 2026 Apple swapped its EU per-install fee for a 5% commission on sales outside the App Store.

AI is the frontier Wu flagged, warning that its market structure is "headed in the direction of reinforcing" incumbents, according to Lowman's review. Agents cut both ways. Amazon's advertising depends on shoppers seeing sponsored placements that an AI assistant can skip, and on August 4, 2026 the Ninth Circuit vacated Amazon's injunction against Perplexity's Comet agent, holding that the user, not the agent's maker, does the accessing. California's antitrust case against Amazon is scheduled for trial on January 19, 2027.

Summary

Who. Tim Wu, Columbia law professor and former White House competition adviser, who wrote the book; the platforms at its centre, chiefly Amazon, Google, Apple and Meta; and the sellers, advertisers, publishers and developers who pay them. Critics include reviewers Kainoa Lowman and Jennifer Szalai and Lawfare's Alan Rozenshtein and Kate Klonick.

What. A name for an economic phase in which dominant platforms earn monopoly rents through fees, take rates, paid placement and control of data and attention, rather than by improving their products, with remedies built on antitrust, neutrality rules and structural separation.

When. The book was published on November 4, 2025, closing a trilogy begun in 2010. On Wu's account the turn came in the 2010s, once Amazon had beaten its marketplace rivals; ILSR put its cut of seller revenue at 19% in 2014.

Where. Mainly the United States, where the book's cases, court rulings and fee data sit, though Apple's European fee changes and AI crawling show the same dispute elsewhere.

Why. For advertisers and publishers, extraction is not an abstraction but a set of numbers: Amazon's advertising revenue, AdX's 20% take rate, Apple's commissions and AI crawl-to-referral ratios. Whether those figures reflect value added or monopoly rent is now being argued in court, and the answer shapes what media costs.
