How AI Will Transform Fintech In 2026

Fintech went from a full-blown surge to a near standstill in just two years. At its peak, about 25 percent of all venture dollars were pouring into the category. By late 2022, that number had collapsed to almost zero. In this conversation, a16z General Partner David Haber and Plaid cofounder and CEO Zach Perret unpack what actually happened during that cycle and why the market is heating up again. We explore how the industry moved from the explosive growth of 2020 and 2021 into a deep freeze, and why we are now seeing real momentum return. We also dig into the forces reshaping fintech today: AI’s outsized impact on fraud and underwriting, incumbents finally embracing external software, the renewed importance of deposits, and the rise of embedded finance across entirely new categories. Zach shares how Plaid has navigated these shifts, what the company is building now, and how he sees the next phase of fintech taking shape Timecodes: 0:00 FinTech’s Seasons 1:10 The Rise of FinTech (2014–2019) 3:32 COVID-19 and the FinTech Boom 4:43 Venture Capital Surge and FinTech Summer 8:25 Solving the Access Problem 10:41 Is Crypto Fintech? 13:51 Plaid’s Evolution and Industry Impact 17:26 Consumer Behavior and Adoption 21:48 Global FinTech Expansion 27:43 2026 Predictions: AI and Fraud 40:26 Emerging Trends in Fintech 43:34 Plaid’s Anti-Fraud and Credit Innovations Resources: Find Zach on X: https://x.com/zachperret Find David on X: https://x.com/dhaber Stay Updated: If you enjoyed this episode, be sure to like, subscribe, and share with your friends!

WHAT IT’S REALLY ABOUT

Fintech’s cycles, maturing infrastructure, and AI-driven fraud reshape 2026 outlook

  1. Fintech moved through distinct “seasons” from late-spring growth (2018–2019) to a COVID-era boom (2020–2021), a sharp funding winter (late 2022), and a gradual thaw back to “spring” by 2024–2025.
  2. Macro shifts—especially the interest-rate cycle—changed fintech business models, pushing many companies from lending/origination dependence toward deposits/float and more full-stack strategies including bank charters and acquisitions.
  3. The industry’s center of gravity has broadened from consumer-point solutions to fintech-as-infrastructure, embedded finance, and software sold into incumbent financial institutions that now adopt third-party technology more readily.
  4. AI is expected to transform workflows inside financial institutions and customer interactions (e.g., agentic experiences like mortgage origination), but the most immediate AI “killer app” is enabling more scalable, sophisticated fraud.
  5. Plaid’s evolution mirrors the market: from account-linking access infrastructure to analytics and risk products, highlighted by its Protect anti-fraud suite and LendScore (cash-flow-based credit scoring) as major near-term growth drivers.

IDEAS WORTH REMEMBERING

Fintech is no longer a niche—it’s increasingly synonymous with financial services.

The conversation frames fintech as having matured from startups delivering digital access into the mainstream fabric of financial services, with banks positioning themselves as large fintech operators and non-financial brands adopting embedded finance.

The rate cycle rewired fintech economics and exposed fragile lending-led growth.

Low rates amplified lending volume and venture exuberance; higher rates compressed lending margins and forced a shift toward deposits/float and stronger balance-sheet strategies, contributing to the post-2022 pullback and subsequent maturation.

“Access” was the first wave; “excellence” (better underwriting, clearer credit) is the next.

They argue the industry largely solved basic digital access (open accounts, move money, apply online), but core systems like credit scoring and fraud remain illogical or opaque—creating room for products grounded in cash flow, explainability, and better risk signals.

AI will accelerate incumbents’ adoption of third-party software because outcomes are obvious.

Unlike prior shifts (e.g., cloud), leaders can personally test AI and see productivity gains, increasing board-level urgency and shortening sales cycles for software that automates compliance, operations, and servicing work previously done manually in “Excel-driven” processes.

The near-term AI winner in finance is the adversary: fraudsters.

Perret predicts fraud will continue compounding (cited at ~18–20% annual growth) because AI scales social engineering, deepfakes, and scams like “pig butchering,” making it harder to stop when the victim is a legitimate user being manipulated.

WORDS WORTH SAVING

It turns out the biggest use case for AI is fraudsters committing fraud against financial services companies.

Zach Perret

Financial fraud is growing at like, like eighteen to twenty percent a year, uh, which is insane, and it's already a huge market.

Zach Perret

I mean, the cat, the cat'll win l-long term, but the mouse is winning right now.

We've solved the access problem. Not completely, not in every little niche, but, but for the most part, we as a collective industry have solved the access problem.

Zach Perret

What we've done is we've taken traditional financial services and we've made it digital. We haven't necessarily made it excellent.
