Rise of Socialism Index

## What this composite measures

The Rise of Socialism Index reads the convergence of two currents — cultural attention and policy-specific interest — to estimate how close socialist-adjacent thinking sits to mainstream electoral viability in the United States. Higher readings indicate stronger upward pressure on capital-side policy: wealth taxation, ownership transparency, antitrust intensity.

## Components

Seven Google Trends signals, each z-scored against a 24-month rolling baseline so absolute search-volume differences between terms don't distort the composite.

| Component | Weight | Transform | Why included | |---|---|---|---| | "Democratic socialism" search interest | 21.4% | 24m z-score | The most precise term-of-art; tracks how often people are actively researching the political project | | "Socialism" search interest | 16.7% | 24m z-score | Broader cultural register; lagging but high-coverage | | "Wealth tax" search interest | 16.7% | 24m z-score | Policy-detail term — the most actionable variant for stewards | | "Tax the rich" search interest | 14.3% | 24m z-score | Populist-slogan variant — distinct attention pattern from the policy-detail term | | "Income inequality" search interest | 11.9% | 24m z-score | Structural-framing term that academics and policymakers use; lagging indicator of mainstream debate | | "Mamdani" search interest | 9.5% | 24m z-score | Proxy for attention on the leading-edge electoral figure of the current cycle | | "Billionaire tax" search interest | 9.5% | 24m z-score | Direct-attack framing of capital concentration |

**Change, 2026-09-23.** A DSA membership estimate (16%) was removed. It was entered by hand, had no live source, and had not updated since May 2026, yet it was still contributing about as much to the reading as the strongest live input. Its weight was spread proportionally across the seven search signals and the index history was recomputed on the new definition. Readings before and after this date are comparable; readings published before it are not. An organized-membership input returns only when a source updates on its own.

## Reading the bands

The index runs 0–100 via sigmoid mapping. Anchor points from the 2024–2026 baseline:

**0–35 — Base state.** Activity confined to coastal urban centers and online discourse. Where the index sat for most of 2024 outside short-lived spikes around the election cycle.

**35–55 — Emerging.** Coverage moves into mainstream business press. State-level wealth-tax bills draw committee hearings. Donor messaging shifts. The summer-2025 reading after the Mamdani NYC primary win sat in this band.

**55–75 — Adopting.** Federal wealth-tax proposals draw double-digit Senate cosponsors. State ballot initiatives qualify. LP letters from major funds reference exposure as material.

**75–100 — Inflection.** Federal proposals reach committee markup. Capital starts pricing in 5–10 year compression in the after-tax IRR on US-domiciled concentrated positions. Material relocation conversations move from speculation to action.

## Why this matters for stewards

The index gives you 12–24 months of warning on three specific changes a steward should track:

**1. Estate and gift-tax basis.** Mainstream-shift readings (55+) historically lead Senate floor activity on estate-tax restructuring by 4–8 quarters. The window to lock in 2017-era valuations and lifetime exclusions narrows as the reading climbs.

**2. State-level wealth-tax exposure.** States with progressive governors and trifecta legislatures (CA, WA, MA, IL, MN, NJ) are the leading edge. The index reading correlates with state-bill introductions roughly two quarters ahead. The federal conversation moves later than the state one.

**3. Founder share-pledge and concentration risk.** When the index moves into "adopting" territory, reset 10b5-1 plans and review banking covenants tied to share value. The political environment shifts faster than the share-price environment, and the leverage built on top of concentrated positions tends to be slow to adjust.

## What this is not

This isn't a market-timing instrument. Index moves don't predict next-quarter equity returns and shouldn't be traded that way. It's a horizon instrument — useful for steering portfolio structure, succession planning, and operating-company domicile decisions across 18–36 month windows.

## What this measures

The Rise of Socialism Index measures how close socialist-adjacent thinking sits to mainstream electoral viability in the United States by combining search interest in political terms and policy proposals. It reads the convergence of cultural attention and policy-specific interest.

## How to read it

Higher readings indicate stronger upward pressure on capital-side policy, wealth taxation, ownership transparency, antitrust intensity. Readings below 35 reflect activity confined to coastal urban centers and online discourse; readings above 55 indicate federal proposals drawing Senate cosponsors and state ballot initiatives qualifying; readings above 75 suggest capital begins pricing in compression of after-tax returns on concentrated US positions.

## What it does not say

The index does not forecast legislation or tax-rate changes. It reflects relative search interest and does not count voters, donors, or likely election outcomes.
