Senate LDA Filings Analysis 2026: Top Spenders and Emerging Trends

The Big Picture: $5.5 Billion on Pace

Federal lobbying has set a new spending record every year since 2019. The $5.08 billion spent in 2025 was itself a 12% increase over 2024. Now, H1 2026 data suggests the trendline is accelerating. At $2.74 billion through June, full-year 2026 is projected to reach $5.5–5.7 billion — an 8–12% increase that would mark the seventh consecutive record year.

The growth isn't uniform. Healthcare lobbying, the largest sector, grew a modest 8%. Defense lobbying surged 45% due to the Iran conflict. Crypto and AI lobbying exploded by triple digits. Energy lobbying grew 28% as permitting reform and trade policy battles intensified. The story of 2026 lobbying is one of established sectors holding steady while new entrants drive the growth.

The number of active registered lobbyists has also increased — to over 12,600, up from 12,100 in 2025. But the more telling number is registered lobbying clients: over 14,200 entities now retain federal lobbyists, up 15% from 2024. More organizations than ever are concluding that they need Washington representation.

The Top 20 Spenders: H1 2026

New Entrants: Who Just Showed Up in Washington

The 1,840+ new lobbying registrations filed in H1 2026 tell us where industries see the next regulatory fights. The largest categories of new registrants are AI startups (180+), crypto and fintech companies (140+), defense subcontractors and tech firms (120+), and healthcare companies responding to drug pricing expansion (110+).

Several high-profile new entrants stand out. xAI, Elon Musk's AI company, registered its first federal lobbyists in Q1 2026. Tether, the stablecoin issuer, hired Washington representation for the first time as the stablecoin bill advanced. Multiple Chinese-owned companies registered lobbyists to fight potential TikTok-style bans and trade restrictions on Chinese-manufactured goods.

The pattern is consistent: companies register lobbyists when regulation threatens their business model. The surge in AI registrations began after Congress introduced comprehensive AI legislation in late 2025. The crypto registrations accelerated after the stablecoin bill cleared committee. The defense registrations followed the Iran supplemental request. Lobbying is reactive — and the reactions tell you where the regulatory pressure is building.

Industry Breakdown: Where the Money Goes

Healthcare remains the largest lobbying sector at $485 million in H1 2026, but its share of total spending has declined from 20% to 17.7% as other sectors grow faster. The healthcare total includes pharmaceuticals ($195M), hospitals and health systems ($112M), insurance ($98M), and medical devices ($80M). Drug pricing remains the dominant issue, but AI in medicine and telehealth regulation are emerging lobbying priorities.

Technology has overtaken finance as the second-largest lobbying sector at $380 million — a milestone that seemed years away as recently as 2024. The tech total includes traditional tech lobbying (antitrust, privacy, trade) plus the AI and crypto spending that has exploded in the last two years. If you separate AI and crypto as distinct sectors, traditional tech lobbying is actually flat; all the growth is in the new categories.

Defense lobbying at $285 million is the third-largest sector — elevated by the Iran conflict from its usual fifth or sixth position. Finance at $265 million has dropped to fourth. Energy at $220 million rounds out the top five, driven by permitting reform, LNG export fights, and tariff-related lobbying by energy-intensive manufacturers.

Quarterly Trends: Q1 vs. Q2 2026

Q2 2026 spending ($1.42B) exceeded Q1 ($1.32B) by 7.6% — an unusual pattern. Typically, lobbying spending is relatively flat across quarters, with slight increases in Q3 and Q4 as appropriations season heats up. The Q2 surge reflects the convergence of the Iran supplemental debate, the stablecoin bill markup, and midterm election positioning.

The Q1-to-Q2 increase was most pronounced in defense (+18% quarter-over-quarter), crypto (+22%), and energy (+12%). Healthcare spending was actually flat between quarters as the drug pricing debate entered a holding pattern. Finance declined slightly (-3%) as the Basel III endgame timeline was extended.

If the quarterly trajectory holds, Q3 2026 could set a single-quarter record. The Iran supplemental will move through conference committee, the AI regulatory framework will see floor action, and pre-election lobbying will intensify. Our projection: Q3 spending of $1.5–1.6 billion.

The Lobbying Firm Landscape: Who's Winning

The top lobbying firms continue to consolidate market share. Akin Gump Strauss Hauer & Feld leads all firms with $52.8 million in H1 lobbying revenue, followed by Brownstein Hyatt Farber Schreck ($48.1M), BGR Group ($38.4M), Holland & Knight ($35.6M), and Squire Patton Boggs ($33.2M).

The fastest-growing firms are those that built AI and crypto practices early. Invariant, a relatively new firm founded by former FTC and DOJ officials, has grown 180% year-over-year on the strength of its AI and antitrust practice. Franklin Square Group, which specializes in fintech and crypto, grew 140%. These boutique firms are winning clients from established shops that were slow to build expertise in emerging technology regulation.

The competitive dynamic is reshaping K Street. Legacy firms are acquiring tech policy practices and hiring from government AI and crypto offices. Boutique firms are expanding into adjacent areas. And in-house lobbying teams — particularly at tech companies — are growing faster than retained firm spending, as companies bring expertise in-house for their most sensitive issues.

What the Data Tells Us About 2027

LDA filings are backward-looking — they report what was spent last quarter. But the patterns in 2026 data point clearly to what's coming. New registrations in AI, crypto, and defense signal that these sectors will continue growing in 2027 regardless of midterm outcomes. The healthcare lobbying plateau suggests the drug pricing fight is reaching a legislative conclusion, one way or another.

The most important trend is the structural increase in total lobbying spending. The $5.5 billion projected for 2026 will likely become $6 billion by 2028. More industries are concluding that Washington representation is a cost of doing business, not an optional expense. The regulatory state is growing in complexity, and every new regulation creates new lobbying demand. It's a self-reinforcing cycle — and the LDA filings document every turn.
