About Silicon Prairie Online

Silicon Prairie Online is the brand used by Silicon Prairie Portal & Exchange, LLC, a JOBS Act-powered Regulation Crowdfunding portal that enables everyday and accredited investors to invest in private businesses through online offerings. The company operates nationally in the U.S. and has roots in the Midwest “Silicon Prairie” startup ecosystem. It is a wholly owned subsidiary of Silicon Prairie Holdings, Inc., which also operates related broker‑dealer and alternative trading system entities to provide a broader capital markets technology stack for private issuers and investors.([linkedin.com](https://www.linkedin.com/company/siliconprairie?utm_source=openai))

A charge from “Silicon Prairie” or “Silicon Prairie Online” on a card statement typically relates to an investment transaction processed through their funding portal—such as purchasing securities (often via Reg CF offerings) in a startup or private company. In many cases, the cardholder will have created an account on the Silicon Prairie platform (web or mobile app) and committed funds to a specific campaign; the portal then processes the payment and remits funds to the issuer, taking its fees from the raise. SEC offering documents for various issuers list Silicon Prairie Online, LLC as the intermediary and detail its commissions and listing fees, confirming its role as the merchant of record for many such transactions.([sec.gov](https://www.sec.gov/Archives/edgar/data/1841998/000118518524001090/abovespace_formca110824.pdf?utm_source=openai))

If you don’t recognize a Silicon Prairie charge, first log into your Silicon Prairie investment account (via sppx.io or the Silicon Prairie app) and review your recent investments, commitments, and payment history—each investment should have an associated transaction record and amount that matches your statement. Check any offering documents or email confirmations you received when investing, as they often specify that payments will be processed by Silicon Prairie Online. If questions remain, contact Silicon Prairie support via the contact links on their portal to request details of the specific charge; be prepared to provide the last four digits of your card, the transaction date, and amount. If you still suspect fraud after speaking with them or cannot match the transaction to an investment, you should then contact your card issuer to dispute or block the charge.

Frequently Asked Questions

Why do I see a charge from Silicon Prairie or Silicon Prairie Online on my card statement?

Silicon Prairie Online processes payments for investments made through its Regulation Crowdfunding portal. If you recently committed funds to a private offering hosted on the Silicon Prairie platform or app, the investment amount (plus any applicable fees disclosed in the offering) will appear as a charge from Silicon Prairie or Silicon Prairie Online on your card statement.

What typical amounts does Silicon Prairie Online charge for transactions?

Transaction amounts depend on the specific investment you made and the minimums set by the issuer—for example, offerings on the Silicon Prairie portal often have minimum investments ranging from about $100 to a few thousand dollars. SEC filings show that Silicon Prairie is compensated by the issuer via listing fees and percentage commissions on the total raised, so you typically see only your investment amount (and any disclosed investor fees) rather than Silicon Prairie’s internal commission structure.([sec.gov](https://www.sec.gov/Archives/edgar/data/1841998/000118518523001114/abovespace_formc.pdf?utm_source=openai))

How can I confirm which investment a Silicon Prairie charge is linked to?

Log into your Silicon Prairie account at sppx.io or through the Silicon Prairie mobile app, go to your portfolio or transaction history, and compare the date and amount of each investment to the charge on your statement. Each investment record should show the issuer’s name, the amount committed, and the date the payment was processed, which you can match to your card transaction.

How do I cancel or reduce an investment I made through Silicon Prairie Online?

Whether you can cancel or reduce an investment depends on the specific offering and its regulatory rules. Within the cancellation window specified in the Form C and portal terms, you can usually log into your Silicon Prairie account, navigate to the offering, and request to cancel or modify your commitment; after the deadline passes, commitments may become irrevocable except in limited circumstances such as material changes to the offering. Review the offering’s disclosure documents and the portal’s terms of service, or contact Silicon Prairie support for guidance on your specific investment.([sphi.io](https://sphi.io/tos/?utm_source=openai))

How can I request a refund for a Silicon Prairie Online transaction?

Refunds generally occur only if an offering is canceled, the minimum funding target is not reached, or your investment is withdrawn within the permitted cancellation window. In those cases, Silicon Prairie will typically return funds to your original payment method or designated account. To inquire about a refund, log into your account, locate the specific investment, and use the portal’s contact or support options to request the status of funds; if the offering has closed successfully, refunds are usually not available except in special circumstances described in the offering documents.([sec.gov](https://www.sec.gov/Archives/edgar/data/1841998/000118518524001090/abovespace_formca110824.pdf?utm_source=openai))

What should I do if I don’t recognize a Silicon Prairie merchant charge?

First, check whether you or someone with authorized access to your card opened an account and invested through Silicon Prairie—search your email for “Silicon Prairie,” “sppx,” or investment confirmations. If you still don’t recognize the charge, contact Silicon Prairie via the support or contact links on their website with the transaction date and amount so they can look it up. If they cannot match the transaction to your identity or you suspect fraud, immediately contact your bank or card issuer to dispute the transaction and request a new card number.

Does Silicon Prairie place temporary authorizations or small test charges on my card?

Like many online financial platforms, Silicon Prairie or its payment partners may place temporary authorization holds on your card or bank account to verify payment details, especially when you first add a funding source. These holds may appear as small amounts and should fall off automatically within a few days if not converted into a finalized transaction; if a small charge does not reverse, contact Silicon Prairie support and your card issuer for clarification.

How can I contact Silicon Prairie about a billing or account issue?

You can reach Silicon Prairie by using the “Contact Silicon Prairie” or support links available on their investor portals (such as sppx.io) or from within the Silicon Prairie mobile app. Provide your full name, the email tied to your account, and details about the charge or investment in question so they can quickly locate your records and respond with specific billing information.([spnb.io](https://www.spnb.io/?utm_source=openai))
