United States Competition Profile

A national view of market structure, industry change, banking, and enforcement. Each series retains its own period and definition; these measures are not a single competition score.

Current competition pulse

Competition cannot be reduced to one number.

The national profile aligns source-specific public evidence systems while keeping each denominator, geography, period, and legal meaning separate.

Observation

Search engines moved from 7,589 in 2025 to 7,359 in 2026 (-230.0 HHI points).

Interpretation boundary

The latest encoded HHI anchor is lower within this documented market series. The change alone does not identify a cause or establish competitive harm.

Comparison contract

Latest observed anchor versus the immediately preceding observed anchor; intervening years are not estimated.

Next research question

Which entry, exit, share, switching, price, quality, or capacity evidence can explain the movement inside this exact market boundary?

Source custody

Each row has its own units, universe, period basis, and scale. Line angle shows direction only; lengths are not comparable and no composite score is calculated.
Competition MonitorLatest versus prior observed anchors across markets, strict Census sector medians, business dynamics, and federal merger activity.

Business dynamics / Business-flow context

United States business dynamics

us-business-dynamics / Establishment entry rate
Canonical dossier

Which sectors, firm-age groups, places, financing conditions, or policy changes account for the latest national entry-rate movement?

202211.65%
-1.04 pp1 year
202310.61%
Empirical methodBusiness-flow context

Disaggregate national entry, exit, job-flow, and reallocation movement by sector, place, and firm age before proposing a competitive mechanism.

Observed comparison

Establishment entry rate moved from 11.7% in 2022 to 10.6% in 2023 (-1.043 percentage points).

Bounded interpretation

The latest published national entry rate is lower than the prior annual BDS record. This business-flow movement does not measure concentration, market power, or a competitive cause.

Latest published Census BDS year versus the immediately preceding national annual record; the full 1978-2023 history remains available in the underlying explorer.

Agenda questions are derived from published latest-to-prior competition signals and remain attached to their exact metric, periods, universe, and source custody. They are not ranked, scored, or treated as findings of causality, competitive harm, liability, enforcement merit, or research importance. Evidence requests describe work to collect, not evidence already established.

Sources reviewed through Jul 21, 2026

This profile keeps market dossiers, national NAICS industry screens, separately bounded state insurance and bank-deposit measures, county bank-deposit screens, federal HSR activity, and dated enforcement records in distinct analytical universes. It does not combine them into a score, treat an industry, state, or county screen as a legal antitrust market, or infer harm or causation from proximity across panels.
