The best company structure for an AI prompt marketplace.

An AI prompt marketplace has two core structural needs. First, it needs to be the merchant of record for customer payments, collecting revenue through a standard processor like Stripe or Shopify Payments. Second, it needs to be able to pay out commissions to prompt sellers globally. This two-sided flow, where the platform takes a fee from the gross sale and remits the net to the seller, presents a funds flow that can be misconstrued as money transmission if not structured correctly.

A US LLC simplifies this. By becoming the merchant of record, the LLC collects the full transaction amount from the end customer. The subsequent payout to the prompt seller is then a simple business expense, a payment to a supplier. This avoids the regulatory complexity of holding funds on behalf of others. The structure must also enable access to US payment processors, which offer better rates and access for USD transactions, and a US business bank account to hold USD balances and make payouts efficiently. This combination of a US entity, a US payment gateway, and a US account is the foundation for managing the unique cash flow of a marketplace model.

A single-member LLC owned by a non-US person is typically treated as a 'disregarded entity' for US tax purposes. This means the LLC itself is not a separate taxpayer; its activities are considered to be those of its owner. This simplicity is its main advantage. It grants the founder a formal US entity with an Employer Identification Number (EIN), which is essential for opening US financial accounts and satisfying the know-your-business (KYB) requirements of processors like Stripe. This allows the business to operate fully within the US ecosystem.

However, it is crucial to understand its limitations. A US LLC does not eliminate your tax obligations in your country of residence. You are still required to report the income from the LLC according to your local tax laws. It does not act as a magic wand for high-risk business models; if the underlying activity is problematic, the corporate wrapper will not fix it. Finally, forming an LLC does not guarantee a bank account. Banking is a regulated activity subject to strict underwriting, and approval is never certain. The LLC is a necessary, but not sufficient, condition for US banking.

For a non-US owner of a disregarded LLC, the central US tax question is whether your income is US-sourced and whether you are 'engaged in a trade or business in the United States' (ETBUS). If you have no US-based employees, offices, or 'dependent agents' working for you exclusively, it is possible that your online business may not be considered ETBUS. If the business is not ETBUS, the owner generally does not owe US federal income tax on its non-US source income. This determination is highly fact-specific and requires analysis from a qualified US tax adviser.

Even if no tax is due, there is a critical reporting requirement. A foreign-owned single-member LLC must file Form 5472 and a pro forma Form 1120 with the IRS annually. These forms report transactions between the LLC and its foreign owner. The penalty for failing to file or for incorrect filing is substantial, starting at $25,000 per form. This is not a DIY task for most founders. It is a recurring compliance cost that must be factored into the decision to form a US entity, and it must be handled by a competent US accountant.

Founders often ask whether to form their LLC in Wyoming, Delaware, or another state. For most non-US founders running an online business like an AI prompt marketplace, the choice has less impact than commonly believed. Neither Wyoming nor Delaware levies state income tax on an LLC whose owner is not a resident and whose income is not sourced there. Both states have strong corporate law precedents and efficient filing systems.

Wyoming is often preferred for its lower annual fees and enhanced privacy; its public registry does not list the names of members or managers. This can be a benefit for founders concerned about public exposure. Delaware is the standard for venture-backed technology companies that intend to raise capital and convert to a C Corporation later, as its Court of Chancery is the preeminent US forum for corporate law disputes. For a bootstrapped AI prompt marketplace that does not plan to seek venture capital, the simplicity, privacy, and lower cost of a Wyoming LLC often make it the more practical choice. The structure is functionally identical for accessing US banking and payments.

The primary commercial reason to form a US LLC is to get a US Employer Identification Number (EIN). This nine-digit number is the universal identifier for businesses in the US financial system. With a registered entity and an EIN, you can apply for a US business bank account and for payment processing with US-domiciled acquirers. For an AI prompt marketplace, this is critical. It allows you to open a Stripe US account, which is a condition for using Stripe Connect to manage payouts to sellers in many jurisdictions.

A US entity allows you to hold USD balances, receive USD payments via ACH or wire in the company's name, and send USD payments more cheaply than via international SWIFT transfers. This is crucial for paying your global base of prompt sellers. Without this US nexus, you would likely be reliant on platforms like Payoneer or Wise, which can be effective but may not integrate as cleanly and can present their own compliance hurdles. The LLC provides the formal identity needed to be a direct customer of US-based financial institutions, from fintech BaaS providers to more traditional banks.

When a bank or payment processor underwrites an AI prompt marketplace, they focus on several key risks. First is intellectual property. They need to see that you have clear terms of service establishing that your sellers own the rights to the prompts they list and grant you the right to market and sell them. The platform must have a clear policy for handling copyright or trademark infringement claims. Second is the two-sided payout model. Compliance teams will scrutinize the flow of funds to ensure it does not constitute unlicensed money transmission. Having clear terms that state the platform is the merchant of record, collecting the full purchase price and then paying sellers their share as a business expense, is vital.

Underwriters will also assess the content itself. Prompts that generate harmful, illegal, or explicit content are a non-starter. You must demonstrate robust content moderation policies. Finally, they will look at the founder's background and business history. Expect a thorough know-your-customer (KYC) check on the LLC's ultimate beneficial owner. A clear, compliant, and well-documented business model is essential for a successful application.

Wyoming, Delaware and Florida are the most common choices for foreign-owned LLCs, but each presents a different profile to a bank or payment processor. A Wyoming LLC offers strong privacy and low annual costs, making it a default choice for many online businesses. However, its reputation as a haven for asset protection can sometimes attract additional scrutiny from compliance departments at more conservative financial institutions.

Delaware is the standard for venture-backed companies, and its name carries a perception of seriousness. For a bootstrapped AI prompt marketplace, this is often overkill. The state's franchise tax and registered agent fees are higher. A Delaware filing signals an intent to raise capital, which may not align with the business model of a solo founder or small team in this niche.

Florida has gained popularity for its low costs and straightforward compliance. As a high-population state with significant real-world commerce, a Florida LLC can appear more grounded than one from a state known primarily for company formations. This can be a subtle advantage when an underwriter is manually reviewing a new business account application for a novel model like a prompt marketplace.

Payment processors view AI prompt marketplaces as a higher-risk category. The core issue is the potential for intellectual property disputes and the subjective quality of the digital goods sold, which can lead to chargebacks from buyers. Stripe is the most common primary processor, but an application will face scrutiny. Underwriters will look for clear terms of service that establish your platform as the merchant of record and define your relationship with prompt sellers.

Expect to provide your EIN, LLC formation documents and a detailed explanation of your payout model. A high number of disputes or chargebacks, especially early on, may trigger a rolling reserve, where Stripe holds back 10-30% of your revenue for 90 days or longer. PayPal may be more permissive for initial setup but is notoriously quick to limit or freeze accounts if their internal risk models flag transaction patterns, such as a sudden spike in payout volume to sellers.

For marketplaces hosted on platforms like Etsy or Gumroad, you are subject to their integrated payment systems. These platforms manage the risk but take a larger cut, and your business is entirely dependent on their rules, which can change with little notice.

The public costs are predictable. State filing fees are a one-time expense, typically $100-300. Annual costs include the state's report fee (around $60 in Wyoming, $300 in Delaware for the franchise tax) and the registered agent service, which ranges from $100 to $250 per year. Do not mistake a cheap first-year agent fee for a low lifetime cost.

Obtaining an EIN from the IRS without a Social Security Number is the main bottleneck. The timeline for this process fluctuates significantly based on IRS backlogs, ranging from four to eight weeks on average. Your LLC is formed, but you cannot open a US business bank account or fully activate payment processing without the EIN.

From filing the LLC to receiving your first customer payout can take 8 to 12 weeks. Week 1: LLC filed. Weeks 2-8: Waiting for EIN. Week 9: Apply for business banking and Stripe. Weeks 10-12: Bank and processor onboarding, which may involve requests for more information. A common stalling point for prompt marketplaces is a processor's compliance team asking for a more detailed breakdown of the seller payout mechanism, delaying settlement.

The process follows a specific sequence. First, we file the Certificate of Formation with the chosen state, typically Wyoming. Once the state confirms the formation, we draft the LLC's Operating Agreement. The next, and most critical, step is obtaining the Employer Identification Number (EIN) from the IRS. This step can involve significant delays if not handled correctly. Once the EIN is issued, the LLC is formally established and ready for the next stage.

Xavion then prepares the banking and payment processing applications. We position your application with US-based financial institutions, including fintech platforms and international banking entities, that have an appetite for this specific business model. The entire process, from formation to having an open account, realistically takes several weeks, and sometimes longer, depending on IRS processing times and bank underwriting queues. We manage the entire administrative sequence, ensuring each step is completed correctly to maximise the probability of a successful outcome. You can start the process at xavioncapital.com/start.
