TL;DR — Quick Summary
- High-risk merchant accounts cost 2–5x more than standard accounts in processing fees, with setup times of 2–6 weeks versus 24 hours for low-risk merchants.
- The three most common high-risk categories — CBD, gambling, and adult — each have unique compliance requirements and acquiring bank restrictions.
- ISOs who specialize in high-risk merchant services earn 2–3x higher residuals per account but face significantly higher chargeback risk and regulatory overhead.
- A POS system with built-in compliance tools and chargeback monitoring is essential for managing high-risk portfolios at scale.

What Makes a Merchant “High-Risk”?
A high-risk merchant is any business that acquiring banks classify as having elevated risk of chargebacks, fraud, or regulatory violations. The classification is not subjective — it is driven by specific underwriting criteria that determine whether a processor is willing to board the account, and at what price.
According to Strategic Treasurer, high-risk merchants typically pay effective rates of 3.5%–7.0% on card transactions, compared to 1.8%–2.5% for standard merchants. The difference reflects the processor’s risk premium: higher chargeback rates, greater regulatory exposure, and the cost of maintaining specialized compliance infrastructure.
For ISOs, high-risk merchant services represent both the highest-revenue and highest-risk segment of the market. The residuals per account are significantly larger, but a single chargeback spike or compliance violation can result in account termination, reserve holds, and financial liability.
CBD Merchants: Navigating the Regulatory Patchwork
CBD (cannabidiol) merchants occupy a unique position in the high-risk landscape. The 2018 Farm Bill legalized hemp-derived CBD at the federal level (containing less than 0.3% THC), but the regulatory environment remains fragmented:
- FDA: Has not approved CBD as a food additive or dietary supplement. CBD products marketed with health claims risk FDA enforcement action.
- State laws: Vary widely. Some states (Colorado, Oregon) have permissive CBD regimes; others (Idaho, Iowa) have significant restrictions on CBD sales.
- Card brand rules: Visa and Mastercard both classify CBD as a high-risk category. Processors must use specific MCC codes (5993 for hemp/CBD products) and are subject to enhanced monitoring.
For ISOs, the key consideration is that CBD merchant boarding requires specialized underwriting. Not all acquiring banks accept CBD merchants, and those that do typically require: lab test results (Certificate of Analysis), state-by-state licensing documentation, website compliance review, and ongoing chargeback monitoring with thresholds below 1%.
Gambling Merchants: Online and In-Person
Gambling merchants are classified as high-risk due to the combination of regulatory complexity, high chargeback rates, and the potential for fraud. The category includes:
- Online gambling: Sports betting, online casinos, poker rooms. Legal in 38 states as of 2026, but each state has its own licensing and regulatory framework.
- Card rooms and casinos: Brick-and-mortar gambling establishments with in-person card processing.
- Fantasy sports: Daily fantasy sports platforms, which occupy a gray area between gambling and skill-based gaming.
The primary risk for gambling merchants is friendly fraud chargebacks — customers who dispute legitimate gambling losses. According to the Merchant Risk Council, gambling merchants experience chargeback rates 2–4x higher than the average e-commerce merchant. ISOs serving this sector need robust chargeback alert systems and representment workflows.
Adult Industry Merchants: Discretion and Compliance
Adult industry merchants face unique challenges beyond standard high-risk underwriting:
- Reputation risk: Many acquiring banks and ISOs refuse to board adult merchants regardless of compliance, due to reputational concerns.
- Age verification: Federal and state laws require robust age verification for adult content and products. Failure to implement adequate age checks can result in both regulatory action and chargebacks.
- Subscription models: Many adult businesses operate on recurring billing, which increases chargeback risk when customers do not recognize charges on their statements.
- Banking access: Adult merchants often struggle to obtain basic business banking services, making them reliant on specialized high-risk processors.
| Category | Effective Rate | Setup Time | Rolling Reserve | Key Risk |
|---|---|---|---|---|
| CBD | 3.5–5.0% | 2–4 weeks | 10–15% | Regulatory patchwork |
| Gambling | 4.0–7.0% | 4–6 weeks | 15–20% | Friendly fraud chargebacks |
| Adult | 4.5–8.0% | 3–5 weeks | 10–20% | Reputation and age verification |
| Standard merchant | 1.8–2.5% | 24 hours | None | Low |
How ISOs Can Profitably Serve High-Risk Merchants
The economics of high-risk merchant services are fundamentally different from standard accounts. Here is how ISOs can build a profitable high-risk portfolio:
- Specialize: Focus on one or two high-risk verticals (e.g., CBD and online gambling) to build deep compliance expertise and banking relationships.
- Charge premium pricing: High-risk merchants expect to pay more. A 0.50–1.00% premium over standard rates is typical and accepted.
- Require reserves: Always require rolling reserves (10–20% for 6 months) to protect against chargeback spikes.
- Monitor aggressively: Set chargeback alerts at 0.5% (well below the 1% card brand threshold) to catch problems early.
- Diversify: Never let one high-risk category exceed 30% of your portfolio. Concentration risk is the biggest threat to high-risk ISOs.

Frequently Asked Questions
What qualifies a merchant as high-risk?
Merchants are classified as high-risk based on several factors: industry type (CBD, gambling, adult), high chargeback rates, regulatory exposure, large average ticket size, recurring billing models, and history of fraud. Acquiring banks evaluate these criteria during underwriting and assign risk categories that determine pricing and reserve requirements.
What is a rolling reserve?
A rolling reserve is a percentage of each transaction (typically 10–20%) that the processor holds in escrow for 6 months to cover potential chargebacks. After 6 months, the reserved funds are released on a rolling basis. For example, if you process $50,000/month with a 15% reserve, $7,500 is held each month and released 6 months later.
Can CBD merchants accept credit cards?
Yes, but only through processors that specialize in high-risk CBD accounts. Standard processors like Square and Stripe typically prohibit CBD transactions. CBD merchants must use specialized high-risk processors with the appropriate MCC code (5993) and acquiring bank relationships that permit hemp-derived CBD products.
How do ISOs make money on high-risk accounts?
ISOs earn significantly higher residuals on high-risk accounts due to the wider spread between wholesale interchange rates and the merchant’s effective rate. A standard merchant at 2.1% might generate 0.15–0.25% in ISO residuals, while a high-risk merchant at 5.0% might generate 1.0–2.0% in residuals. However, the risk of account termination and chargeback liability is proportionally higher.
What happens when a high-risk merchant exceeds the chargeback threshold?
When a merchant’s chargeback rate exceeds 1% of total transactions (the card brand threshold), the processor may: increase the rolling reserve, impose additional fees, restrict processing volumes, or terminate the account. Visa’s Fraud Monitoring Program and Mastercard’s Excessive Chargeback Program both have escalating intervention levels that can result in fines of $5,000–$25,000 per month for persistent violators.
Conclusion
High-risk merchant services are not for every ISO — but for those willing to invest in specialized underwriting, compliance infrastructure, and chargeback management, the revenue opportunity is substantial. CBD, gambling, and adult merchants pay premium processing rates and generate residuals 2–3x higher than standard accounts.
The key to success in high-risk is infrastructure: a POS platform with built-in chargeback monitoring, reserve management, and multi-category portfolio support. Without it, the operational overhead of managing high-risk accounts will erode your margins faster than the residuals can build them.
