Public brief / source-backed packet

Cross-domain competition briefing

Orient readers to observed changes, evidence custody, and the questions that still require investigation. This packet keeps 4 latest-to-prior observations across 4 evidence systems separate and does not rank or combine them.

01

Defined markets / HHI

Search engines

-230
20257,589
1 year
20267,359

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

Research questionWhich entry, exit, share, switching, price, quality, or capacity evidence can explain the movement inside this exact market boundary?
02

Census industries / Median HHI

Information

+172.9
2017568.5
5 years
2022741.4

The 2022 median is higher than the 2017 median across the same published strict-match screen. Sector medians are orientation statistics, not sector HHI values or legal market findings.

Research questionWhich six-digit industries drive the sector shift, and where do product, geography, entry, conduct, price, quality, or enforcement records justify deeper market-level research?
03

Geographic systems / State median HHI

Statewide branch-deposit screens

-55
2015958
10 years
2025903

The later branch-deposit screen is lower than the 2015 anchor. This descriptive movement does not define a legal banking market, identify a cause, or measure every banking product.

Research questionWhich state-specific paths, ownership-reporting changes, branch-booking patterns, entry, exit, or consolidation events account for movement beneath the cross-sectional median?
04

Federal merger activity / Transaction volume

Hart-Scott-Rodino program

-25
FY20242,031
1 year
FY20252,006

The latest reported transaction volume is lower than the prior fiscal year. This is a program-activity comparison, not a finding about merger harm or enforcement effectiveness.

Research questionHow did filing mix, transaction size, thresholds, exemptions, and macroeconomic conditions change alongside notification volume?
Interpretation boundary

Every signal compares declared observed anchors inside the same series or cross-section. Missing years are not interpolated, intervals are not annualized, and market, industry, geographic, business-flow, and merger measures keep separate units, universes, period bases, and legal meanings. Antitrust Radar does not combine them into a composite competition score.

Packet access4 signals / 5 canonical sources / Jul 19, 2026

Publication standard

A briefing is a research handoff, not a finding of liability.

Every exported packet carries the observed comparison, source register, bounded interpretation, next research question, and the global no-composite-score rule.

  1. 01
    State what changed

    Report the exact prior and latest anchors with their period basis and interval.

  2. 02
    Keep systems separate

    Do not compare the magnitude of unlike HHI, share, business-flow, transaction, and review-rate changes.

  3. 03
    Open the investigation

    Route each signal into its underlying profile, explorer, source records, and research question.

The studio packages current observations; profiles, explorers, reports, and public data remain the authoritative analytical surfaces.
