Tech Weekly: When Giants Stumble and Quantum Threats Loom
Article on Rise N Shine Blog, written by Arthur R McPhee.
The week ending November 2, 2025, delivered a reminder that even the largest players in fintech can stumble. While Fiserv's historic stock collapse dominated headlines, a quieter convergence of threats and opportunities emerged across quantum computing, cryptocurrency markets, and global fintech innovation hubs. This wasn't just another news cycle. It was a snapshot of an industry at an inflection point.
For anyone tracking tech, business, or digital assets, last week's developments carry implications that extend far beyond quarterly earnings reports. The convergence of agentic AI with quantum computing is moving from theory to practice. Cryptocurrency markets are inching toward mainstream legitimacy through ETF approvals. And the geography of fintech innovation is shifting beneath our feet. Here's what happened, what it means, and where to look next.

The Fiserv Collapse: A $30 Billion Warning
Fiserv's stock didn't just drop on October 29. It collapsed. The payment technology giant lost 44% of its value in a single day, erasing roughly $30 billion in market capitalization. That's not a correction. That's a confidence crisis.
The numbers were brutal. Fiserv reported third-quarter adjusted earnings of $2.04 per share against analyst expectations of $2.65. Revenue came in at $4.92 billion versus the anticipated $5.36 billion. Organic revenue growth slowed to just 1% year-over-year. The company simultaneously slashed its full-year 2025 guidance from an expected $10.15 to $10.30 EPS range down to $8.50 to $8.60.
CEO Mike Lyons, who assumed the role in January 2025, acknowledged reality bluntly during the earnings call. "Our current performance is not where we want it to be nor where our stakeholders expect it to be," he said. The company blamed deteriorating economic conditions in Argentina, which had contributed 10% of organic growth the previous year, among other factors.
But the real story lies in what Fiserv did next. The company announced a complete leadership overhaul. Takis Georgakopoulos, who joined as COO in April, and Dhivya Suryadevara, former CEO of Optum Financial Services, were appointed co-presidents effective December 1. Paul Todd, former CFO of Global Payments, took over as CFO on October 31. The board of directors underwent significant restructuring with three new members joining January 1, 2026.
Fiserv also announced a move from the New York Stock Exchange to Nasdaq, effective November 11, where it will trade under its original ticker "FISV." The company unveiled a "One Fiserv" action plan focused on client-first operations, building its Clover small business platform, delivering AI-enabled operational excellence, and disciplined capital allocation.
The market reaction suggests investors believe this will take time. One analyst described the results as "abysmal" and the magnitude of the miss as "difficult to comprehend." The collapse adds to broader concerns about whether payment processors are entering a post-boom phase as transaction growth slows globally.
For smaller fintech players and startups, Fiserv's stumble creates opportunity. When incumbents face execution risk and investor skepticism, gaps open. The question is whether nimble competitors can move fast enough to capture market share while Fiserv attempts its multi-quarter recovery.
Quantum Computing Meets Agentic AI: The Convergence Accelerates
While Fiserv struggled with quarterly results, a more fundamental shift continued gathering momentum. The convergence of agentic AI with quantum computing is no longer a future scenario. It's happening now, and the implications stretch across fintech, biotech, and cryptography.
Agentic AI refers to systems that can make decisions, set goals, and take actions based on context and learned experience. When paired with quantum computing's ability to process thousands or millions of potential solutions simultaneously, these systems become exponentially more capable.
By mid-2025, companies like IBM and Google had made quantum services available through cloud-based platforms. The technology has reached early commercial maturity in the United States. Quantum computing in 2025 is actively contributing to molecular simulations, complex optimization, and encryption challenges.
The fusion creates entirely new modes of reasoning and automation. Agentic systems can use quantum hardware to rapidly explore large solution spaces, learn from outputs, and adjust strategies in real time. Quantum systems benefit from AI-driven optimization, where agents help refine circuit designs or quantum algorithms based on desired outcomes.
This isn't just academic. In fintech, the convergence enables more sophisticated risk modeling, fraud detection, and portfolio optimization. Early adopters are testing quantum-enhanced reinforcement learning for trading strategies and quantum-assisted financial modeling.
But the convergence cuts both ways. The same technology that enables breakthrough applications also threatens existing security infrastructure. More on that shortly.
XRP ETF Watch: The Approval Timeline Tightens
Ripple's Swell 2025 event took place November 4-5 in New York, bringing together senior executives from BlackRock, JPMorgan, CME, Nasdaq, and Franklin Templeton. The presence of Maxwell Stein, BlackRock's Director of Digital Assets, sparked speculation about potential XRP ETF announcements, though BlackRock has stated it has "no plans" for an XRP ETF currently.
The real movement happened elsewhere. Seven U.S. spot XRP ETF filings are currently under Securities and Exchange Commission review, with decisions expected between October 18 and November 14. Ripple's State of the XRP Ledger Q3 2025 report revealed that XRP has now met a key regulatory condition: XRP futures began trading on Coinbase Derivatives Exchange on April 21, 2025, and on CME Group on May 18, 2025.
The SEC's updated listing framework requires a minimum of six months of regulated futures trading before any spot crypto ETF can be listed. Based on this timeline, XRP completes its six-month futures requirement by late November, allowing for potential SEC approval and a U.S. spot XRP ETF launch by the end of 2025.
Market data platform Polymarket shows greater than 99% probability that the SEC will approve a spot XRP ETF by year-end 2025. That level of confidence reflects strong institutional expectation that XRP will follow Bitcoin, Ethereum, and Solana in joining the U.S. ETF market.
Spot XRP ETFs for Solana, Litecoin, and Hedera began trading on Wall Street in late October 2025. Three spot XRP ETFs launched in Canada in June 2025, while Hashdex introduced the world's first XRP spot ETF in Brazil in April. The U.S. market appears to be following international precedent.
The legal uncertainty around XRP has also been resolved. On August 7, Ripple and the SEC jointly dropped their appeals, confirming Judge Analisa Torres' July 2023 ruling as final judgment. Ripple agreed to pay a $125 million civil fine to close the matter. With the case legally settled, the path to ETF approval appears clear, barring unexpected regulatory concerns.
The Quantum Threat to Crypto: Not If, But When
Here's where the quantum-AI convergence becomes a problem. Blockchain technology relies on cryptographic algorithms that a sufficiently powerful quantum computer could break. The threat isn't theoretical anymore. It's a matter of timing.
A Federal Reserve study published in October 2025 warned that quantum computers could eventually unlock the private history of Bitcoin and other blockchain networks. The report focused on "harvest now, decrypt later" (HNDL) attacks, where adversaries collect encrypted blockchain data today and store it until quantum computers become powerful enough to decrypt it.
The study noted that when "Q-Day" arrives—the moment quantum computers can routinely break existing encryption—data secured by traditional cryptography could be instantly compromised. But HNDL means the risk starts now, not later. Anyone who copies a blockchain ledger today could decrypt it in the future, potentially revealing digital signatures and wallet ownership.
Experts estimate that within a decade, powerful quantum machines may crack encryption securing up to 25% of all Bitcoin, particularly coins stored in legacy wallets with exposed public keys. Google scientists estimate that a million-qubit quantum computer could break RSA-2048 encryption in about a week—a task that would take conventional computers roughly 300 trillion years.
BlackRock quietly updated its iShares Bitcoin Trust filing in May 2025 to flag quantum computing as a potential risk to Bitcoin's long-term security. The filing specifically warned that quantum technology could "undermine the viability" of cryptographic algorithms used not just in digital assets but across the global tech stack.

The good news is that post-quantum cryptography standards are emerging from organizations like NIST and ENISA. Some blockchains are taking action. Algorand has integrated Falcon, a post-quantum digital signature algorithm vetted by NIST. The Quantum Resistant Ledger was built from day one with this threat in mind, using XMSS instead of traditional cryptography.
But most major networks haven't made the transition. Even though NIST standards are solidifying, valuable networks still use ECDSA without quantum-resilient upgrades. The crypto industry is prioritizing hypergrowth over responsible scaling, according to industry observers. That could prove costly.
The Geography of Innovation: Emerging Markets Rise
While Western fintech giants like Fiserv struggle, emerging markets are gaining momentum. India, in particular, has emerged as a global fintech powerhouse.
India is home to 12,894 fintech companies, including 1,612 funded firms that have collectively raised $33.8 billion. The country hosts one decacorn, 25 unicorns, and 87 soonicorns with a combined valuation of $125 billion. In Q3 2024, India climbed to second place globally for fintech funding, attracting $778 million—a 66% increase from the previous year.
The momentum continued into 2025. In the first half of 2025, India saw 99 deals accounting for $1.5 billion in fintech investment. Major raises included $200 million by investment platform Groww, $171.8 million by asset financing company IKF Finance, and $78 million by contactless payments firm ToneTag.
Bangalore (Bengaluru) now ranks among the top global fintech cities, climbing past Los Angeles in recent rankings. The city is home to 438 fintech startups and has been dubbed the "Silicon Valley of India." It benefits from India's digital finance revolution, government initiatives promoting cashless transactions, and a vast young population with increasing internet penetration.
Beyond India, other emerging markets are making moves. Jakarta moved up four positions to become the #2 emerging startup ecosystem globally, benefiting from increased early-stage capital access and a thriving fintech scene. Istanbul climbed 10 spots to #3, driven by improvements in performance, funding, and market reach.
The shift suggests that fintech innovation is no longer concentrated in traditional hubs like Silicon Valley, New York, and London. Talent, capital, and innovation are flowing to regions with large unbanked populations, favorable regulatory environments, and government support for digital transformation.
For Western startups and investors, this creates both competition and opportunity. Emerging market fintech companies often build solutions for unique local challenges that can scale globally. Partnerships and cross-border collaboration may become increasingly valuable.
What This Means for Tech Strategy
The past week's developments point to several strategic considerations for anyone building, investing in, or writing about technology.
First, incumbent advantage is fragile. Fiserv's collapse shows that even massive, established players can lose investor confidence quickly when execution falters. For startups, this means windows of opportunity open during incumbent weakness. The challenge is moving fast enough to capitalize.
Second, security infrastructure requires immediate attention. The quantum threat to cryptography isn't a 2030 problem. It's a 2025 problem because of harvest-now-decrypt-later attacks. Any organization dealing with sensitive data, financial transactions, or blockchain technology should be evaluating post-quantum cryptography now.
Third, geographical assumptions about innovation are outdated. The narrative that meaningful fintech innovation only happens in a few Western cities no longer holds. India, Southeast Asia, and other emerging markets are producing unicorns and driving adoption at scale. Global competition is intensifying, not just among established hubs but from unexpected places.
Fourth, the convergence of AI and quantum computing will reshape competitive dynamics. Organizations that can leverage this convergence for optimization, security, or decision-making will gain advantages. But the technology bar is high, requiring both quantum and AI expertise plus substantial capital investment.
Fifth, regulatory clarity creates opportunity. The path to XRP ETF approval shows how legal resolution and regulatory frameworks enable institutional capital flows. For crypto and digital assets, regulatory legitimacy appears to matter more than technological superiority.
Comparison: Fintech Leadership Responses to Market Pressure
What to Watch Next Week
Several developments bear watching as November progresses.
The SEC decision window for XRP ETF applications closes mid-November. If approvals come through, expect significant market movement and potentially a rush of similar applications for other altcoins.
Fiserv's new leadership takes formal roles in early December. Their first 90 days will signal whether the "One Fiserv" plan represents genuine strategic change or just repackaging.
Quantum computing announcements from IBM, Google, and other major players could provide clarity on Q-Day timelines. Any breakthrough in qubit stability or error correction will be significant.
Emerging market fintech funding trends in Q4 2025 will indicate whether the shift toward India and Southeast Asia is sustainable or temporary.
And watch for how traditional financial institutions respond to cryptocurrency ETF approvals. The presence of BlackRock, JPMorgan, and others at Ripple Swell suggests institutional interest is real, but translating interest into product launches takes time.
The tech industry spent the past week demonstrating that nothing is guaranteed. Not market position. Not encryption security. Not geographical dominance. The winners in 2026 will be those who saw these signals and adjusted accordingly.
