Venture capital is undergoing a dramatic polarization in 2025. At one extreme, massive mega-rounds are flowing almost exclusively to AI companies. At the other, private equity is stepping in to fill the middle-market gap. Meanwhile, traditional small-to-medium VC deals are quietly disappearing.
This shift is fundamentally reshaping who gets funded, how companies scale, and what it even means to be “venture-backable.”
As 2025 comes to an end, several defining trends stand out.
The AI Mania: A New Gold Rush
The gold rush is back—only this time, the gold is AI.
Venture capital firms are chasing AI deals with unprecedented intensity, often at eye-watering valuations. After eight straight quarters of declining VC investment, 2025 began at a low point and ended on a hot streak, with three consecutive quarterly increases. The rebound, however, came with a caveat.
Strip out AI, and the recovery all but disappears.
According to the SVB Innovative Economy Outlook, for the first time more mega-deal dollars flowed into AI companies ($73 billion) than into non-AI companies ($47 billion).
“Capital is consolidating because AI companies have scaled incredibly fast and achieved outsized outcomes with far smaller teams relative to the capital they raise,” explains Michelle Kwok, Principal at Draper Associates. “When a category consistently produces hockey-stick growth curves, the market shifts accordingly. With enough momentum and hype, dollars always follow.”
That concentration is playing out clearly at the portfolio level. DMZ Financials & Holdings deployed 68% of its capital into AI-centric deals in 2025, with the remaining 32% spread across all other verticals. According to Dimitriy Mishin, venture investor and serial entrepreneur, key portfolio companies include You.com, Reflection AI, Sent.dm, Tahcar, Anyroad, Watt Data and WalkWay AI. The firm also increased exposure to AI-focused funds such as AiX Ventures and Day One Ventures.
Austin Walters, Managing Partner at SpringTide Ventures, compares AI to prior platform shifts. “AI is the next tech tsunami, creating an order of magnitude more return value than previous waves like cloud and handheld computing. Software ate the world—and now AI is eating software.”
Bigger deals, fewer companies
Unsurprisingly, AI’s rise has pushed capital toward mega-rounds—funding rounds of $100 million or more.
In 2025, these deals accounted for a record share of venture funding: roughly 60% globally and 70% in the U.S., according to Crunchbase. December alone saw Saviynt, an AI identity security platform, raise $700 million. Other notable mega-rounds went to companies like Fervo Energy, Boom Supersonic and Fal, which raised $140 million for its generative AI platform.
But volume does not always equal quality.
“AI deal flow has exploded, but differentiation is narrowing,” Mishin warns. “Much like the dot-com boom, skeptics predicting a bubble aren’t entirely wrong. A glut of AI-peripheral companies is being funded, and most will be wiped out when a correction occurs. That said, true leaders will survive—and those companies can become trillion-dollar industry Goliaths.”
For many investors, concentrating capital is a deliberate strategy. Writing larger checks for fewer companies increases exposure to power-law outcomes rather than chasing marginal returns across sub-scale bets.
The Disappearing Middle
As mega-rounds surge, early-stage funding tells a different story.
Crunchbase data shows a steady decline in the number of seed deals, even as total dollars invested at the seed stage remain relatively stable. In other words, seed rounds are getting larger—but far harder to secure.
So what does this mean for founders outside the AI spotlight?
“This is a tougher time,” says Dimitriy Mishin, venture investor and serial entrepreneur. “You might have a great product, an exceptional team or impressive revenue growth—but right now, you’re simply not ‘in fashion.’”
Raising $10–$20 million rounds is still possible, but founders must be more strategic. “Don’t approach funds that are already heavily exposed to AI,” Mishin advises. “Look for investors whose portfolios align with your sector.”
Walters agrees that smaller deals still exist, but notes that headline statistics are distorted by the explosive growth in assets under management at the largest VC firms, which are overwhelmingly focused on mega-deals.
Kwok argues that what many describe as the “disappearing middle” is actually a redefinition of venture capital itself.
“This forces venture back to its original purpose—backing non-consensus outliers early, with conviction, before the world understands them,” she says. “At Draper, we spend much of our time in frontier biotech, aerospace, robotics and deep tech. These areas require underwriting technical risk and longer time horizons. Not all VCs are ready for that yet—but you can feel the shift coming.”
What’s In Fashion Now
According to Crunchbase, just a few years ago, venture dollars were widely distributed across sectors—from food tech to health tech to robotics—and across all stages of growth. Today, capital is far more selective.
“If you’re not following the current trends, you’re effectively out of the game,” Mishin says. “Fashion today is cross-industrial AI. Second is climate tech. Third is dual-use and defense tech.”
Founders operating outside these areas should expect lower valuations compared to AI companies—or compared to valuations seen three to four years ago.
Defense tech, in particular, is emerging from the shadows. According to the SVB Innovative Economy Outlook, more VCs are explicitly naming defense tech as a focus area than ever before. Firms such as Andreessen Horowitz, Founders Fund, Lux Capital and General Catalyst are increasingly backing “dual-use” technologies that span civilian and military applications, including AI, autonomy and cybersecurity.
Private Equity’s Venture Invasion:
As venture capital concentrates at the extremes, private equity is quietly moving in.
PE firms are increasingly investing in later-stage, venture-backed companies—and in some cases, “eating VC’s lunch.”
Several forces are driving this shift:
- The search for growth: PE firms, historically focused on stable, mature businesses, are drawn to the growth and returns of technology companies.
- Longer private lifecycles: Startups are staying private longer, creating a pool of mature companies well-suited to PE investment.
- Record dry powder: PE firms are sitting on vast amounts of undeployed capital and are expanding into new stages to put it to work.
- VC exit pressure: With IPO markets constrained, PE buyouts provide a viable liquidity path for VC portfolios.
- Blurring strategies: Large VC firms are raising growth funds and registering as RIAs, while PE firms are adopting venture-style approaches.
- Operational expertise: Modern PE brings hands-on value creation—optimizing operations, improving margins and executing acquisitions.
- Risk mitigation: Later-stage investments offer PE firms lower risk than early-stage venture, with meaningful upside intact.
For founders navigating today’s polarized capital landscape, the message is clear: venture capital hasn’t disappeared—but it has changed. Understanding where your company fits in this new reality may determine whether you raise capital at all, and from whom.
