Litigation Trends to Watch for 2026: Antitrust, Adtech Suits, and Contractor Tax Crimes — What Small Businesses Need to Know

A fast-moving legal road ahead — and why your small business should care now

Litigation trends in 2026 are shaping into three clear hotspots that will affect small businesses: renewed antitrust pressure in real estate, a spike in high-stakes adtech contract lawsuits, and intensified criminal enforcement of contractor tax crimes. If you run a brokerage, an adtech startup, or a contractor-heavy operation, these are not abstract headlines — they are immediate operational and financial risks. This article synthesizes late‑2025 and early‑2026 developments and gives you a practical, prioritized playbook to prepare, prevent, and respond.

Topline forecast for 2026 — the three litigation hotspots

Short version: expect more antitrust suits targeting industry rules and steering practices in real estate; more contract‑breach and data‑misuse cases in adtech with large damages; and a stepped‑up criminal tax enforcement track aimed at contractors and cash‑intensive service operations. Each trend is already visible in recent case developments and federal prosecutions.

1) Antitrust in real estate: expanded scrutiny beyond NAR

Late 2025 and early 2026 litigation shows a renewed focus on how listing, MLS rules, and commission practices affect competition. Cases like the Zea v. NAR‑related litigation (filed in 2023 and producing fresh briefing through 2025–26) illustrate plaintiffs are testing enforcement theories that MLSs and associations can be held responsible for policies that allegedly “steer” buyers and restrict nontraditional brokerage models.

Why this matters: smaller brokerages and flat‑fee models are now prime targets or bystanders in suits that seek injunctive relief, expanded disclosures, or rule enforcement — outcomes that can force system changes and sudden compliance costs.

2) Adtech contract suits: data access, scraping, and multimillion-dollar damages

The January 2026 jury verdict finding EDO liable to iSpot and awarding $18.3M highlights how contract and trade‑secret claims in adtech can produce big damages. That suit turned on alleged unauthorized access to proprietary measurement dashboards and reuse of data beyond licensed purposes. Expect more suits like this as firms monetize datasets and APIs, because the costs of litigation often outweigh the settlement value for larger damages.

Why this matters: if your business shares data with partners, uses third‑party measurement tools, or relies on scraped/aggregated feeds, a downstream contract suit can threaten revenues and reputations.

3) Contractor tax crimes: criminal enforcement and heavy restitution

Federal prosecutors are increasingly pursuing tax evasion and filing fraud against owners of contractor, restoration, and cash‑intensive businesses. High‑profile examples through early 2026 — including the Rhode Island public adjuster sentenced for tax evasion with more than $1.3M in restitution — show prosecutors seek prison time, probation, and large restitution orders even in repeated offender cases.

Why this matters: small businesses that misclassify workers, underreport cash receipts, or lack robust payroll/1099 practices are at risk of civil penalties and criminal prosecutions.

Why these trends are intensifying in 2026

• Regulatory focus and resources: state AGs and federal agencies (DOJ, FTC, IRS Criminal Investigation) have signaled antitrust and tax enforcement priorities for 2026.
• Data economy pressures: higher valuations on proprietary datasets mean more contract enforcement and trade‑secret disputes.
• Judicial receptivity: courts are entertaining novel claims tied to marketplace steering, API misuse, and contract scraping which broaden exposure for smaller players.
• Technology amplifies risk: easy scraping, automated ad measurement, and complex vendor chains create gaps in access control and provenance.

Who among small businesses is most exposed?

Several business models face elevated risk in 2026:

• Independent brokerages, IDX/MLS data resyndicators, and flat‑fee listing services
• Adtech platforms, analytics vendors, and data resellers that integrate third‑party feeds
• Contractor businesses: public adjusters, restoration firms, landscapers, and gig‑economy agencies with irregular payroll practices
• Companies with weak vendor contracts or lax access controls over proprietary dashboards

Early warning signs — signals you should watch now

1. Increased auditing or discovery requests from partners or competitors regarding data access logs.
2. Requests from brokers or platforms to change commission or listing display practices.
3. Unexplained gaps in tax paperwork: missing 1099s, shifting revenue reporting, or off‑books cash handling.
4. New regulations or AG inquiries in your state referencing MLS rules, adtech data privacy, or tax compliance campaigns.
5. Internal complaints about unauthorized data exports or suspicious vendor behavior.

Practical legal preparedness checklist — prioritized and pragmatic

Below is an operationally oriented checklist you can implement in 30, 90, and 180‑day phases. Each item is action‑oriented and tailored to the 2026 enforcement climate.

Immediate (0–30 days)

• Preserve evidence: implement a litigation hold for relevant data. Stop routine deletion or auto‑purge of logs and communications.
• Run a quick contracts inventory: identify all agreements with data partners, adtech vendors, broker partners, and major contractors.
• Tax triage: ensure payroll and 1099 reporting for the prior two tax years is externally reviewed by a CPA.
• Get counsel on deck: retain an attorney with experience in antitrust or data contract litigation and a tax crime specialist — do not use in‑house general counsel only.

Short term (30–90 days)

• Strengthen access controls: limit dashboard access, implement role‑based permissions, and enable immutable logging for data exports.
• Revise vendor contracts: add explicit permitted‑use clauses, audit rights, IP ownership language, and dispute resolution provisions. Consider liquidated damages for unauthorized use.
• Implement tax controls: formalize expense and revenue recognition policies, centralize invoicing, and document cash handling procedures.
• Insurance review: check coverage for cyber, D&O, EPLI, and professional liability. Ask carriers about contract breach and regulatory defense limits.

Medium term (90–180 days)

• Compliance program: build a lightweight compliance manual that covers data sharing, antitrust awareness, and tax reporting policies.
• Training: run manager trainings focused on data access rules, vendor onboarding, and payroll/1099 compliance.
• Red team your contracts: simulate a vendor dispute to test data provenance, logs, and contractual remedies.
• Implement a privileged investigative workflow: set up an internal counsel‑led process for privileged internal investigations.

Key contract language to consider (practical examples)

Below are compact clause ideas to discuss with counsel. These are for planning — work with an attorney to integrate and tailor language.

• Permitted Use: "Data Recipient shall use Data solely for the narrow purpose of [specified purpose]. Any secondary use requires prior written consent and is a material breach."
• Audit & Logs: "Provider may audit Recipient twice annually upon 30 days notice; Recipient shall maintain immutable access logs for no less than 36 months."
• IP & Ownership: "All aggregated or derivative datasets created from Provider Data are the exclusive property of Provider unless expressly licensed."
• Remedies: "In addition to injunctive relief, parties agree liquidated damages of $[X] per violation and recovery of attorneys' fees for enforcement actions."

How to respond if you get sued or investigated — an immediate 7‑step playbook

1. Stop and preserve: issue a litigation hold for emails, logs, and relevant records — include custodians and cloud providers.
2. Engage experienced counsel: contact antitrust/data litigation counsel or a tax criminal defense attorney as applicable.
3. Limit communications: centralize all external communications through counsel. Do not volunteer statements to regulators or media.
4. Forensics: retain a neutral forensic vendor to map access logs, export trails, and system snapshots.
5. Insurance notice: notify carriers early — many policies require prompt reporting to preserve coverage.
6. Assess settlement vs. litigation: counsel should run a damages and exposure model within 14–30 days to guide strategy.
7. Consider voluntary disclosure: for tax issues, a voluntary disclosure to IRS criminal investigation can mitigate outcomes but must be managed with counsel.

Preserve, consult, and centralize: in 2026, the speed of discovery and forensic capability make early evidence preservation and counsel engagement the single biggest determiners of outcome.

Case forecasting — plausible scenarios small businesses should prepare for

Forecasting litigation is probabilistic, but practical scenarios to plan for include:

• Regional brokerages hit with steering claims: plaintiffs seek class‑wide injunctive relief to change listing displays or buyer referral flows.
• Adtech cross‑claims: subcontractors and analytics firms are sued for scraping or republishing proprietary dashboards, with multimillion‑dollar damages like the EDO‑iSpot verdict.
• Criminal tax prosecutions against contractors: recurring pattern—civil audits escalate to criminal referrals, resulting in restitution and potential incarceration.

Advanced strategies — legal tech and data governance for 2026

Beyond basic compliance, leading small businesses are implementing three higher‑value defenses:

• Immutable audit trails: use blockchain or append‑only logs for critical datasets and access events to produce tamper‑resistant evidence.
• API gatekeeping: throttle, watermark, and token‑bound APIs to manage downstream uses and trace bad actors.
• Predictive litigation modeling: integrate simple exposure dashboards that map contract terms to potential damages scenarios so leadership can make informed settle vs litigate decisions.

Future outlook — regulatory and market trends for late 2026 and 2027

Expect the following through 2027:

• State AG coordination: multistate antitrust and adtech investigations will increase; small firms operating across borders should prepare for parallel inquiries.
• More private plaintiffs: class actions and private enforcement will remain attractive where statutory damages are not required but injunctive relief is.
• Tax enforcement specialization: DOJ and IRS will target sectors with repeat patterns of underreporting — expect targeted outreach campaigns and public indictments to deter others.
• Contract standardization: industry associations will accelerate model contract terms to reduce disputes — participating early can provide influence and protection.

Actionable takeaways — what to do this week

• Run a 30‑minute risks meeting with legal, finance, and operations to map your exposure to the three hotspots.
• Identify your top five data partners and request a permissions and log report for the past 24 months.
• Order an external tax compliance review for payroll and 1099 reporting for the last three years.
• Place a hold on routine log deletion and consult counsel on a preservation protocol.

Final recommendation — convert risk into managed cost

Litigation trends in 2026 are not a single crisis; they are a persistent shift in enforcement and private litigation incentives. The right approach treats legal risk like operational risk: identify, quantify, mitigate, monitor, and insure. Small businesses that move quickly to shore up contracts, data governance, and tax controls will preserve capital and strategic optionality.
