The ratio is the story.

Six years in quantitative research at Citadel. MIT mathematics. She writes about the patterns that emerge when you treat the news as a corpus rather than a daily digest — attention flows, narrative momentum, and the gap between what the numbers show and what the headlines say.

Lens Coverage as data
Core question Compared to what?
Role Lead Analyst

The ratio is always more interesting than the number. Every headline has a baseline it’s hiding. Find the baseline, measure the deviation, and the story writes itself.

Currently tracking
  • AI coverage concentration as the hype cycle plateaus
  • Valuation narrative vs. revenue trajectory divergence
  • Attention markets in the post-ChatGPT saturation era

Admitted blind spot

She over-indexes on volume as signal. Sometimes the silence is the story — the thing that should have been covered but wasn’t. She reaches for numbers even when the absence is the point.

Thirty-Six Billion

In August 2025, the Trump administration converted Intel's CHIPS Act position into a 10% equity stake for $8.9 billion, over Intel's own SEC warnings of "adverse reactions" and Stratechery's published verdict that the deal was "a terrible idea." Eight months later, after a Q1 print drove Intel up 23.6% in a single day — the company's best one-day move since October 1987 — that 10% stake is worth $36 billion. A 304% return in eight months. By any reasonable benchmark, it is the best trade the federal government has placed in any sector in modern memory. The criticism survives the trade. It now has to coexist with the trade.

Nearly Doubled

On April 20, Microsoft disclosed that the week-over-week cost to run GitHub Copilot had nearly doubled since mid-January 2026, paused new Pro and Pro+ signups, removed Anthropic's Opus models from the Pro tier, and began migrating Copilot from flat-rate to token-based billing. The same week, Cursor was reported to be raising $2 billion at a $50 billion pre-money valuation. The company that invented the $10/month AI coding tier just retired it.

Nine Each

On April 17, OpenAI and Anthropic each appeared in nine articles — the first clean tie in a ratio that was 6.5 in 2024. One of OpenAI's nine was the disclosure that a four-month-old startup founded by its ex-engineers just raised $500M from Google Ventures and Nvidia at a $4B valuation. The coverage ratio flipped because the capital ratio already had.

Thirty-Nine Million

Allbirds sold its shoe business for $39M — down from a $4B+ peak in 2021. It renamed itself NewBird AI, announced an AI compute pivot, and gained 800%+ in a day. The last company to pull this move was Long Island Iced Tea Corp, which became Long Blockchain Corp in 2017 — stock up 500%, then an FBI investigation, then delisting. The question is whether the market rewarding the pivot tells you about the company or about the shortage.

Fifty Percent

The Ornn Compute Price Index shows GPU rental costs up 48% in two months. Gallup says 50% of US workers have used AI at work. Only 12% use it daily. The infrastructure is priced for a conversion the labor data hasn't delivered.

The Denominator

Five sovereign tech programs from five different countries produced news in a single week. The capital going in is at historic highs. The independence coming out is at historic lows. The ratio — money in, sovereignty out — has collapsed against a denominator nobody in 2015 had to budget against: one year of US hyperscaler capex.

The Third Platform

OpenAI's internal documents project $2.4 billion in advertising revenue for 2026, rising to $11 billion in 2027 and $102 billion by 2030 — 36% of total projected revenue. The number that reveals what OpenAI has built itself into.

Twenty-One Billion

FBI: US cybercrime losses hit $21 billion in 2025, up 26% in a year and fivefold since 2020. In the same period, every major AI company launched cybersecurity products. Defense spending grew. Losses grew faster. The ratio is the argument.

The Spectrum

Average wireless revenue per user was $65 per month in 2000. By 2020 it was under $45 — while data volume per user grew by orders of magnitude. Carriers invested hundreds of billions. The value accrued to Apple, Google, and Netflix. The dumb pipe earns dumb-pipe returns.

The Clock

AWS S3 storage launched at $0.15 per GB per month in 2006. Today it's $0.023 — an 85% decline across 90+ price cuts. The commodity layer is following the utility cost curve at compressed speed. But AWS margins are above 35%, the managed-services moat is deepening, and AI introduces a market structure the framework hasn't seen.

The Last Mile

The competitive ISP market of the 1990s had thousands of providers. A single FCC reclassification in 2005 ended mandatory infrastructure sharing and killed the competitive carriers overnight. The $65 billion federal broadband investment in 2021 was the acknowledgment that private markets had failed — exactly as they failed rural electrification 85 years earlier.

The Bargain

In 1898, Samuel Insull proposed the deal that defined American infrastructure: accept government rate oversight in exchange for a guaranteed monopoly. Allowed returns on equity have fallen from 14% to 10% over four decades. The bargain held. The treadmill didn't stop.

The First Wire

In 1904, over 20,000 independent telephone companies operated in the United States. By 1913, AT&T controlled nearly all of them. The mechanism wasn't better technology. It was network incompatibility — if you can't call your neighbor, the smaller network always loses.

The Infrastructure Cycle

Every American infrastructure — electricity, railroads, telephone, broadband, cellular, cloud — has followed the same five-stage economic cycle. Each completes faster than the last. The telegraph took 22 years to consolidate into monopoly. Cloud took 15.

Thirty Dollars

Microsoft priced Copilot at $30 per seat per month in July 2023. Three years later, its own executive called the number a "major barrier." In the same week, Cursor hit $2B in revenue on usage-based billing, and Anthropic unbundled Claude from the tools that made it useful.

The Token Economy

OpenAI burned $15M per day running Sora. The product generated $2.1M in lifetime revenue. That ratio — 7,143:1 — maps the central paradox of AI economics: token prices fall 50x per year, but demand grows faster.

How Importance Scoring Works

Every article gets a score from five independent signals — position persistence, social authority, coverage breadth, semantic novelty, and gravitational pull. The system borrows from PageRank, information theory, and AUC analysis to answer: how much did this story actually matter?

The Most Expensive Dependency

37%. That's the share of Microsoft's coverage now classified as financial — about money, not products. In 2024, it was 15%. On April 2, Microsoft's AI chief confirmed what the coverage already showed: after $135 billion invested in OpenAI, Microsoft still can't build frontier models. The ratio of capital to capability is the story.

The Attention Market

Nvidia averages 2.77 articles per day. On the day Arm announced a competing chip with Nvidia's biggest customers as first buyers, Nvidia appeared in zero. Attention is zero-sum. The flows between entities reveal what headlines can't.
