Rain Valuation Approaches $20 Billion: The Battle for U-Cards Extends to Rewards Systems

Foresight NewsPublished on 2026-06-17Last updated on 2026-06-17

Abstract

Rain, a stablecoin payments infrastructure company, is shifting the competitive focus for U Cards from simple issuance to user retention and repeated usage. On June 15, Rain launched "Rain Rewards," an embedded loyalty program capability within its card-issuing infrastructure. This allows partner businesses—like fintech platforms and neobanks—to configure branded loyalty points, earning rules, redemptions, and merchant promotions directly within their card products. The system, built from the 2025 acquisition of Uptop, ensures points are only issued upon final transaction settlement, preventing liabilities from refunds. Trials, such as with Avalanche Card, reportedly boosted spending by 25% among enrolled users. Founded by Farooq Malik and Charles Yoo-Naut, Rain evolved from a tool for managing Web3 company expenses into a full-stack enterprise platform. It is a Principal Member of Visa and Mastercard, enabling partners to issue stablecoin-backed cards and wallets while leveraging traditional payment networks. Notably, the popular U Card Plasma One is issued by Rain under Visa's authority. Rain also integrates with Visa's stablecoin settlement pilot, using USDC for network settlement. Rain's rapid funding reflects growing institutional interest in stablecoin payment infrastructure. It raised a $245 million Series A in March 2025, a $58 million Series B in August 2025, and a $250 million Series C in January of this year, reaching a $19.5 billion valuation. Annualized transac...

The next phase of competition for U-Cards might not be about issuing the cards themselves, but about who can get users to use them repeatedly.

On June 15, Rain announced the opening of its rewards program to platform partners. This is a loyalty capability directly embedded within Rain's card-issuing infrastructure. Partners can configure the name of the points, earning ratios, redemption methods, bonuses, and merchant subsidy campaigns within their own card products.

On the surface, Rain Rewards is a points and loyalty feature for card programs; but within the context of Rain's overall business, it more closely resembles a crucial puzzle piece for its stablecoin payment infrastructure.

Rain is a stablecoin payment infrastructure company. It serves not retail users, but enterprises, neobanks, fintech platforms, developers, and AI agents. Partners can use Rain to issue stablecoin-backed cards and wallets, accessing on/off ramps, cross-border payments, rewards programs, and risk control capabilities. For end-users, the experience might just be a card that can be used for both offline and online purchases; for enterprises, Rain provides a complete back-end system for integrating stablecoins into traditional payment networks.

Card Rewards Program: Retention is Paramount

The core of Rain Rewards is not about moving points on-chain, but about embedding the rewards program into the card-issuing infrastructure itself.

According to Rain's announcement on June 15, any partner running a card program on the Rain platform can launch a private-label loyalty program without having to integrate a third-party points provider separately or build a rewards system from scratch. Rain stated that during a private test of this rewards program with Avalanche Card, cardholders who joined the program had a 25% higher spend than those who did not.

Its mechanics also align more closely with financial infrastructure than a typical marketing tool. Points, earning rules, and redemption are all handled within the same system that processes spending and settlement. Furthermore, points are only generated on-chain after a transaction is finally completed, ensuring refunds or reversals do not leave behind difficult-to-manage liabilities.

Partners can set the program name, points-back percentage, category bonuses, merchant subsidy campaigns, allow users to offset their bills with points within their own app, or redeem for hotels and flights through a white-labeled travel portal.

This capability stems from Rain's acquisition of Uptop in November 2025. Uptop was an on-chain rewards platform that had provided rewards systems for clients like the Cleveland Cavaliers and the Detroit Pistons.

After acquiring Uptop, Rain integrated the rewards capability into its own card and wallet platform, forming a more complete enterprise-grade payment product stack.

This point is critical. If stablecoin cards only solve the 'can you spend' problem, it's difficult to compete with mature credit cards and fintech products. In reality, card programs compete for user frequency, merchant subsidies, benefit design, and brand affinity. By building Rewards into its underlying system, Rain essentially allows partners to have an operational consumption growth tool at their disposal as soon as they issue a stablecoin card.

What is Rain: The Backend for Stablecoin Payments

Rain was co-founded by Farooq Malik (CEO) and Charles Yoo-Naut (CTO).

Based on a 2022 interview with the two founders by Circle Ventures, we can see their starting point wasn't stablecoin cards from the outset, but rather a 2021 side project called SignandWire. This project initially aimed to embed payment functionality into electronic signature workflows. Later, an entrepreneur asked if USDC could be used as a payment method within signed investment documents, which led Farooq Malik and Charles Yoo-Naut to focus on the near real-time settlement capabilities of stablecoins. They first integrated USDC on Ethereum for SignandWire, and later, upon request from Solana ecosystem entrepreneurs, integrated USDC on Solana.

In discussions with Web3 entrepreneurs, the pair identified a more frequent pain point: many DAOs, protocol teams, and native on-chain companies held large amounts of crypto assets but still had to use temporary off-ramps, reimbursements, and manual processes to pay for real-world expenses like GitHub, SaaS, travel, and computers.

Rain initially evolved around the spend management needs of such teams, providing corporate cards and expense management tools, acting as a conversion layer between the traditional financial system and Web3 treasury systems. Subsequently, Rain's business expanded from DAO spend management to stablecoin card issuance, wallets, settlement, and enterprise-grade payment infrastructure, continuing this underlying logic: enabling on-chain assets to enter real-world payment scenarios in ways familiar to businesses and merchants.

Today, Rain is a Principal Member of Visa and Mastercard, enabling partners to offer stablecoin-backed credit cards, prepaid cards, and related wallet capabilities through the two major card networks.

In 2025, Rain also joined Visa's stablecoin settlement pilot and claimed to have migrated its Visa card settlement to USDC, enabling settlement with Visa 7 days a week, 365 days a year. When a user spends with a Visa card issued by Rain, Visa still settles with the merchant acquirer via conventional processes, while Rain uses stablecoins to complete network settlement in the backend.

Notably, the recently popular U-Card Plasma One is also issued by Rain under a Visa authorization.

In other words, Rain's role is not to replace existing payment networks, but to connect stablecoin settlement, card issuance, wallet, and compliance capabilities to traditional card networks, allowing enterprises to use one set of infrastructure to bring on-chain funds into offline and online consumption scenarios.

Accelerated Fundraising: From Series A to Series C in 10 Months

The pace of Rain's fundraising reflects the repricing of stablecoin payment infrastructure over the past year.

In March 2025, Rain announced the completion of a $24.5 million Series A funding round led by Norwest Venture Partners, with new investors including Galaxy Ventures, Goldcrest, Thayer, Hard Yaka joining, and existing investors like Lightspeed Venture Partners, Coinbase Ventures, Vinyl Capital, Canonical Crypto, and Latitude Capital participating further. Rain stated at the time that its transactions covered over 100 countries, with growth exceeding 15x in the past 12 months.

Five months later, in August 2025, Rain completed a $58 million Series B funding round led by Sapphire Ventures, with participation from Dragonfly, Galaxy Ventures, Endeavor Catalyst, Samsung Next, Lightspeed, and Norwest. Rain announced in the statement that transaction volume had grown 10x since January 2025, with Visa card programs processing millions of transactions in over 150 countries.

In January of this year, Rain completed a $250 million Series C funding round led by ICONIQ, with participation from Sapphire Ventures, Dragonfly, Bessemer Venture Partners, Galaxy Ventures, FirstMark, Lightspeed, Norwest, and Endeavor Catalyst.

Following this round, Rain's valuation reached $19.5 billion, with total funding exceeding $338 million. Rain also disclosed an annualized transaction volume of over $3 billion, serving over 200 partners, including Western Union, Nuvei, and KAST.

The most notable aspect of these figures isn't just the funding amounts themselves, but the time density. Rain progressed from Series A to Series C within 10 months, indicating that institutional capital is beginning to view stablecoin payments not just as a crypto concept, but as enterprise-grade financial infrastructure.

From Human Cardholders to AI Agents: Rain Aims to Secure the Programmable Payment Gateway

Rain's product line is no longer just a stablecoin card.

On June 9, 2026, Rain launched Agent Control Layer. This feature allows enterprises and developers to define the spending boundaries for AI Agents at the infrastructure level, including acceptable merchant categories, approved merchants/payees, transaction amounts, transaction frequency, number of available Agent cards, and card validity periods. Rain stated these rules are enforced before card issuance or transaction initiation, not after the fact.

This extends Rain's payment system from "humans using cards" to "machines using money." If AI agents in the future need to subscribe to software, book travel, execute procurement, or pay suppliers, the first problem enterprises need to solve is not the payment button, but the permission boundary: who can spend, when, to whom, and up to how much. Stablecoins provide programmable money, card networks provide merchant reach, and the control layer gives enterprises the confidence to embrace this automation.

From Agent Control Layer to the card rewards program (Rewards), Rain's path is becoming increasingly clear. Its goal is not a point product, but a stablecoin payment operating system: Cards are responsible for reaching merchants, wallets for holding assets, on/off ramps for connecting fiat, Rewards for retention, and the Agent Control Layer for managing permissions and compliance in automated payments.

The mainstream adoption of stablecoin payments may not happen within exchange interfaces. It might appear in a corporate card, a cross-border salary payment, a cup of coffee, or a virtual card temporarily generated by an AI Agent. Rain aims to be behind these transactions, enabling on-chain funds to flow where users don't even notice.

Has the Crypto Market Bottomed? Here's What Institutions Think

The crypto market is in a period of significant debate, with leading institutions offering differing views on whether a bottom has been reached. Three prominent firms have published detailed analyses: * **Galaxy Digital** argues Bitcoin has **not yet bottomed**. Their analysis of 13 historical indicators across six dimensions (valuation, profit-taking, miner pressure, etc.) shows only four are fully met. They project a potential bottom range between $30k and $54k. * **NYDIG** states a bottom is **possible but not likely**. While metrics are close to historic bear market extremes, they note the absence of a classic panic-selling event. They also suggest increased institutional adoption may have structurally altered the market cycle, potentially leading to a shallower downturn. * **Standard Chartered Bank** asserts the **bottom has already occurred** at around $59k. They cite two key factors: potential US-Iran diplomatic progress and the anticipated SpaceX IPO, which they believe absorbed capital and caused ETF selling pressure that is now subsiding. They forecast a year-end price target of $100k. Despite the surface-level disagreement, the reports share critical common ground more valuable for long-term investors: 1. All three believe the market bottom will form **within this year**. 2. All agree the current price is **closer to the bottom than to previous highs**. 3. All maintain a **bullish long-term outlook** for Bitcoin and a new cycle. The core takeaway is that while the exact bottom price ($40k, $50k, or $60k) is debated, the consensus is that a bottom is imminent. For long-term holders, the primary focus should not be pinpointing the absolute low, but on the future potential for prices to reach $100k, $200k, or higher. The fundamental thesis for Bitcoin—sovereign debt accumulation, inflation, declining trust in centralized institutions, global digitization, and improved accessibility—remains intact and is arguably strengthening. The overall landscape is viewed as more favorable than in previous crypto winters.

The 'Chip' Challenge and Breakthroughs in China's Optical Industry Chain

China's Photonics Industry: Bottlenecks and Breakthroughs In the global AI race, computing chips dominate the narrative, but the underlying bottleneck increasingly defining the scale of AI clusters is light—or more specifically, optical connectivity. Optical modules, which translate electrical signals to light and vice versa, are crucial for connecting thousands of GPUs in AI data centers, preventing data congestion and ensuring efficient model training. High-speed modules (800G, 1.6T) are now standard, with performance hinging on advanced DSP (Digital Signal Processor) chips. This is where a critical dependency lies. Two US giants—Marvell and Broadcom—collectively dominate over 90% of the high-end DSP chip market. Chinese optical module leaders like Zhongji Innolight and Eoptolink rely on these chips to manufacture modules for overseas AI customers, primarily in North America. While this creates a supply chain vulnerability, complete decoupling is difficult. Marvell derives over half its revenue from Greater China, and the US firms depend on Chinese partners for chip packaging and optical components. The risk from laser chips (e.g., from Lumentum), another key component, is considered more manageable due to multiple global suppliers and faster progress in domestic alternatives from companies like YOFC and Accelink. To mitigate risks, China's industry is pursuing a multi-pronged strategy: diversifying supply chains and locking in long-term orders; fostering a domestic market ecosystem to adopt homegrown DSPs from firms like Huawei HiSilicon and CETC; accelerating R&D in high-speed DSPs and advanced packaging; and investing in next-gen technologies like silicon photonics and Co-Packaged Optics (CPO) to reduce reliance on discrete DSPs. The ultimate solution lies not in short-term博弈 but in persistent advancement of domestic high-end chip R&D and manufacturing. While challenges remain in performance, certification, and ecosystem building, China's vast domestic market and manufacturing base provide a crucial buffer, buying time for the industry to achieve greater technological independence.

Behind SpaceX's $2 Trillion Market Cap: Why Does Musk Always Have the Next Move Planned?

On June 12th, SpaceX debuted on the Nasdaq, reaching a valuation that briefly touched $2 trillion. This marked the culmination of a 24-year journey from its founding in 2002, driven by Elon Musk's frustration at the high cost of buying rockets. The company's path was defined by early failures, with its first three Falcon 1 launches ending in explosions before a successful 2008 flight opened the era of commercial spaceflight. Key to its model was a fixed-price NASA contract, incentivizing cost reduction. SpaceX mastered rocket reusability, first achieving a Falcon 9 landing in 2015, which drastically cut launch costs. This enabled its profitable Starlink satellite internet constellation, envisioned years before reusability was proven, to create an internal market for frequent launches. Similarly, the next-generation Starship rocket was in development long before its first flight, with its business case evolving from Mars colonization to supporting the emerging concept of in-orbit data centers for AI—a story now central to its valuation. The company's recent IPO, a reversal of its long-standing "no IPO" stance, is funding this ambitious "space-based compute" vision. While major tech players like Google, Blue Origin, and others are investing heavily, significant technical and cost hurdles remain. Ultimately, SpaceX's history is one of creating its own demand: first with Starlink and now with space-based AI compute, betting that its next rocket will enable its next giant market.

USDe Circumvents GENIUS Act Yield Ban: How Synthetic Dollars Became Crypto's Most Successful Gray Area?

In drafting the GENIUS Act, Congress prohibited licensed payment stablecoin issuers from paying interest or yield to holders—a rule that forced changes for USDC. However, Ethena's USDe, a rapidly growing "yield dollar," operates outside this regulation. USDe is a delta-neutral synthetic dollar backed by crypto collateral and hedged perpetual futures positions, generating yield from funding rates rather than traditional reserves. Because it doesn't fit the legal definition of a payment stablecoin, the GENIUS Act's restrictions do not apply. USDe's supply peaked above $14 billion in 2025, making it a top-three dollar-denominated crypto asset. Its model carries distinct risks, notably dependence on sustained positive funding rates and vulnerability during market deleveraging events, as seen in a brief depeg in October 2025. Regulatory approaches differ: Germany's BaFin banned USDe sales, viewing it as an unregistered security, while U.S. institutional capital, like Janus Henderson, has embraced it for treasury management. The GENIUS Act defined and regulated payment stablecoins but left synthetic dollars like USDe in a gray area. The unresolved question is whether future regulations will address this category or if yield will continue migrating to undefined spaces.

When Crypto Meets the World Cup: CoinW and Modrić's Art of "Navigating Cycles"

When Encryption Meets the World Cup: CoinW and Modrić's "Transcending Cycles" Philosophy In the context of the 2026 FIFA World Cup and its massive global audience, the crypto exchange CoinW announced football legend Luka Modrić as its global brand ambassador. This move is framed not merely as a marketing tactic, but as a strategic experiment in user profile migration. It targets mature, financially stable football fans—particularly in Europe, Southeast Asia, and Latin America—who traditionally have low crypto awareness but value trusted, time-tested authority figures like Modrić. The article draws parallels between Modrić's enduring, disciplined career—marked by consistency and success at the highest level over two decades—and CoinW's own development path. Founded in 2017 during a volatile industry period, CoinW focused on building robust infrastructure and risk management. It weathered the 2022 industry crisis without major security incidents, subsequently earning recognition like "Europe's Most Trusted Exchange" and growing to over 20 million registered users. This "long-termism" is translated into user-centric products. CoinW Academy lowers the initial knowledge barrier. Its integrated ecosystem (CoinW, GemW, DeriW, PropW) and the recent launch of a TradFi section—offering perpetual contracts on traditional assets like stocks, gold, and oil—aim to create a unified platform for diverse assets. For the World Cup, CoinW launched the "We Are The Game" campaign, collaborating with Alchemy Pay to offer zero-fee deposits and local payment options, aiming to transform spectators into participants and lower entry barriers. Ultimately, CoinW's sports partnerships and product strategy are presented as a concerted effort to build trust and accessibility for the "silent majority" still outside crypto—shifting the industry narrative toward inclusivity and long-term value.
