The US Cards and Payments Market in 2025: Strategic Positioning in the Age of Amazon and TikTok-Driven E-Commerce

The U.S. cards and payments market in 2025 is no longer a story of incremental change—it's a seismic shift driven by the twin engines of Amazon's dominance in traditional e-commerce and TikTok's explosive rise in social commerce. These platforms are not just reshaping how Americans shop; they're redefining the very infrastructure of digital payments, open banking, and mobile wallet adoption. For investors, this is a golden opportunity to position capital in companies and technologies that are at the intersection of convenience, innovation, and consumer behavior.

Amazon: The E-Commerce Behemoth and Payment Infrastructure Builder

Amazon remains the uncontested leader in traditional e-commerce, with U.S. consumers projected to spend $400 billion on its platform in 2025. Its recent launch of Haul, a mobile-only, ultra-affordable e-commerce platform, underscores its commitment to capturing the mobile-first market. Haul's integration with Amazon's existing payment systems—digital wallets, one-click purchases, and recurring billing—has normalized frictionless transactions for millions.

Amazon's strategic investments in embedded finance, such as BNPL (Buy Now, Pay Later) services and merchant lending, are also leveraging open banking APIs to streamline financial data sharing. For example, Amazon's partnership with Parafin to offer algorithmic cash advances to small sellers relies on real-time data from open banking platforms. This not only enhances Amazon's ecosystem but also creates a flywheel effect: more sellers adopt open banking tools, which in turn attracts more consumers to the platform.

TikTok Shop: The Social Commerce Revolution

While Amazon dominates the practical, transactional side of e-commerce, TikTok Shop is rewriting the rules of impulse-driven shopping. With U.S. social commerce sales expected to hit $85.58 billion in 2025 (a 19.5% growth year-over-year), TikTok's integration of live shopping, influencer-driven campaigns, and in-app payments is creating a new paradigm.

The platform's success hinges on three pillars:
1. Impulse Purchases: TikTok's algorithm-driven product recommendations and viral trends drive spontaneous buying.
2. Micro-Transactions: The average order value on TikTok Shop is $43, reflecting a shift toward low-cost, high-frequency purchases.
3. Influencer Commerce: 78% of TikTok shoppers discover products through influencers, creating a direct link between social media and e-commerce.

TikTok's in-app payment systems—powered by partnerships with fintechs and open banking APIs—are enabling seamless transactions without leaving the platform. This is particularly appealing to Gen Z and Millennials, who prioritize convenience and social engagement. However, TikTok's future in the U.S. remains uncertain due to regulatory scrutiny, making it a high-reward, high-risk bet for investors.

Open Banking: The Invisible Backbone of Digital Payments

Open banking, though slower to adopt in the U.S. compared to Europe and Asia, is gaining traction as e-commerce platforms demand faster, more secure transactions. By 2025, 52% of U.S. adults use at least one open banking-enabled service, driven by partnerships between banks, fintechs, and platforms like Amazon and TikTok.

Key developments include:
- Real-Time Payments (RTPs): Amazon and TikTok are integrating RTPs via FedNow and NACHA's Innovation Alliance to enable instant settlements.
- Account-to-Account (A2A) Transfers: These bypass traditional card networks, reducing fees and increasing security.
- Embedded Finance: Open banking APIs allow platforms to offer financial services (e.g., BNPL, cash advances) directly within their ecosystems.

For investors, open banking represents a $1.2 trillion global opportunity by 2030. Fintechs like Plaid and MX, which provide open banking infrastructure, are critical players. Additionally, regional banks partnering with fintechs to offer data-sharing APIs are well-positioned to capture market share.

Investor Opportunities: Where to Place Bets

1. Digital Wallets and Payment Processors:
2. Apple Pay and Google Pay: With 40% of U.S. online transactions processed through mobile wallets in 2025, these platforms are foundational.

3. Stripe and PayPal: These companies are adapting to the TikTok-driven shift toward in-app payments and BNPL.

4. Social Commerce Platforms:

5. TikTok Shop: Despite regulatory risks, its growth in the U.S. is undeniable. Investors should monitor its ability to navigate political challenges while scaling.

6. Meta's In-App Payments: Meta's mandate for merchants to use its checkout system could unlock $94.5 billion in social commerce payments by 2030.

7. Open Banking Enablers:

8. Plaid and MX: These fintechs provide the APIs that power real-time data sharing and A2A transfers.

9. Regional Banks: Institutions like U.S. Bancorp and PNC are expanding open banking partnerships to stay competitive.

10. Fraud Detection and Security:

11. As social commerce grows, so does the risk of scams. Companies like LexisNexis and ID.me, which use AI to detect synthetic identities, are becoming essential.

Risks and Strategic Considerations

• TikTok's Regulatory Uncertainty: A potential U.S. ban could disrupt its social commerce momentum. Diversification into platforms like Instagram and Snapchat is crucial.
• Consumer Trust: Only 47% of U.S. consumers trust products bought via social media. Brands must prioritize transparency and quality.
• Competition from Traditional Retailers: Walmart and Costco are investing in social commerce to counter Amazon and TikTok.

Conclusion: Positioning for the Future

The U.S. cards and payments market in 2025 is a battleground of innovation, where convenience, speed, and personalization are the new currency. Amazon's ecosystem and TikTok's social commerce model are not just trends—they're transformative forces. For investors, the key is to back companies that bridge the gap between emerging platforms and open banking infrastructure while addressing consumer trust and regulatory risks.

The time to act is now. The winners in this space won't just survive—they'll dominate.
