01
Technology & Electronics
Platform monopolization claims modeled on the Google Search and Meta cases, app-store commission and anti-steering restraints (Epic v. Apple), self-preferencing by dominant marketplaces, standard-essential patent hold-up and FRAND disputes, no-poach and wage-suppression agreements among tech employers, digital-advertising auction manipulation, and component-cartel matters such as DRAM, LCD, capacitor, and lithium-ion battery price-fixing.
02
Transportation
Airline merger challenges (JetBlue–Spirit, American–US Airways), capacity-discipline and fuel-surcharge price-fixing conspiracies, ocean shipping alliance rate-setting under the Shipping Act, freight forwarder and rail-rate cartels, and rideshare driver-classification and pricing-algorithm cases. Antitrust scrutiny extends to slot allocation at congested airports, code-share arrangements, and loyalty-program tying.
03
Professional Sports
League-imposed restraints on player mobility, franchise relocation, and territorial exclusivity raise core Sherman Act questions. Representative matters include challenges to broadcast and streaming rights pooling, salary-cap and draft restrictions tested against the non-statutory labor exemption, NCAA name-image-likeness restraints after Alston, single-entity defenses under American Needle, and exclusive-dealing claims involving apparel, ticketing, and sports-data providers.
04
Consumer Goods
Resale price maintenance and minimum-advertised-price programs under Leegin, exclusive dealing and category-captain arrangements with major retailers, indirect-purchaser class actions under Illinois Brick repealer states, private-label tying, and horizontal price-fixing among manufacturers of staples (canned tuna, packaged seafood, chocolate, generic drugs). Recent matters also target algorithmic pricing tools that facilitate tacit collusion.
05
Healthcare
Pharmaceutical reverse-payment (pay-for-delay) settlements under Actavis, product-hopping and citizen-petition abuse, hospital and physician-group consolidation challenged by FTC and state AGs, PBM rebate-walls and formulary exclusion, medical-device tying and bundled rebates, GPO sole-source arrangements, and biosimilar entry-blocking. Insulin and EpiPen pricing litigation illustrates the multi-defendant supply-chain theory.
06
Energy
OPEC+ coordination and downstream price-fixing among refiners (as alleged in the D'Augusta gasoline litigation), pipeline and LNG terminal access denials, electricity capacity-market manipulation under FERC, oilfield-services no-poach agreements, midstream gathering monopolies, and renewable-credit and REC market collusion. Sherman Act monopolization theories increasingly target vertically integrated utilities and grid operators.
07
Finance
Benchmark manipulation (LIBOR, ISDAfix, FX, Treasury auctions), interchange-fee and merchant-restraint litigation against Visa and Mastercard, stock-loan and CDS market boycotts, prime-brokerage exclusive dealing, credit-card network merger challenges (Capital One–Discover), and HFT order-routing claims. Antitrust overlay extends to ratings-agency conduct and consortium-owned trading venues.
08
Farmers & Agriculture
Broiler-chicken, pork, beef, and turkey processor price-fixing under the Sherman Act and Packers and Stockyards Act, dairy cooperative supply-management cartels, seed and crop-protection consolidation (Bayer–Monsanto, ChemChina–Syngenta), grower-contract tournament systems, fertilizer cartels, and grain-handling and rail-car allocation restraints affecting farmers as direct sellers.
09
Casinos
Gaming-license market division among regional operators, sports-betting platform exclusivity and state-monopoly grants, hotel-room rate algorithms (Rainmaker/Cendyn-style) on the Las Vegas Strip, tribal-compact exclusivity disputes, slot-machine manufacturer tying with management services, and labor-side no-poach agreements among casino-resort operators.
10
Newspapers & Media
Newspaper joint-operating agreements under the Newspaper Preservation Act, broadcast-station and cable-system merger review, retransmission-consent collective bargaining, ad-tech monopolization claims paralleling the DOJ Google case, news-aggregator and search-snippet copyright/competition disputes, and music-licensing collective conduct by ASCAP, BMI, and SESAC consent-decree matters.
11
Space
Launch-services market concentration and EELV/NSSL procurement exclusion, satellite-bandwidth and orbital-slot coordination at the ITU, vertically integrated launch-plus-constellation foreclosure theories (Starlink-style), ground-station and tracking-network access denials, and exclusive government-contract steering. Emerging issues include in-or-orbit servicing standards and lunar-resource extraction rights.
12
Travel
Online travel agency parity clauses (Booking, Expedia MFNs) tested in EU and U.S. courts, global distribution system tying, hotel-chain merger review (Marriott–Starwood), all-inclusive resort and timeshare market allocation, cruise-line port-access exclusivity, and airline-hotel-rental car loyalty-program bundling. Recent algorithmic-pricing litigation targets hotel revenue-management software.
