U.S. Venture Capital Investment in AI Surges Despite Exit Challenges
Recent analysis from the PitchBook-NVCA Venture Monitor indicates that massive investments in artificial intelligence have propelled U.S. venture capital deal values to 44% above the previous annual record, even as the year approaches its final quarter. Despite this remarkable financial activity, the rate of exits necessary to return that capital to investors has lagged significantly behind.
A substantial portion of the $515.8 billion deployed within the first three quarters of this year was directed toward leading AI firms, specifically OpenAI Group PBC and Anthropic PBC. Collectively, these companies secured over $200 billion in funding during the first half of the year. Analysts at PitchBook observe that without these funding rounds, the overall investment trends have largely remained consistent since late 2024.
In the third quarter, the value of venture capital deals fell by approximately 40%, amounting to $98.4 billion, with most of this decline attributed to drops in venture-growth rounds. Nevertheless, startups continued to secure funding at nearly record levels, with PitchBook estimating about 5,012 deals in the quarter, marking one of the busiest periods since early 2022.
Artificial intelligence dominated the investment landscape, accounting for a record 82.7% of the year’s total deal value. However, its percentage of quarterly contributions has been gradually declining since January, dipping to 65.9% in the third quarter. Notably, Databricks Inc. received the largest individual funding in this period, totaling $5 billion, a stark contrast to the triple-digit billions raised by various labs earlier this year, as reported by PitchBook.
PitchBook has expressed concern regarding the challenges associated with capital returns. Nizar Tarhuni, Executive Vice President of Research and Market Intelligence at PitchBook, highlighted that “the real story sits on the exit side.” He pointed out that the timeline for initial public offerings (IPOs) continues to extend, thus forcing sellers to rely on mergers and acquisitions for liquidity.
One significant transaction in the third quarter significantly influenced exit numbers: Space Exploration Technologies Corp. (SpaceX) completed a $60 billion all-stock acquisition of Anysphere Inc., the developer behind Cursor. This deal alone accounted for 53.1% of the quarter’s total exit value and ranks as the second-largest acquisition of a venture-backed company on record, following SpaceX’s earlier acquisition of xAI Inc.
Excluding the SpaceX deal, the total exits for the quarter amounted to just $53 billion, marking the lowest level since late 2024. Noteworthy deals included Salesforce Inc.’s $3.6 billion acquisition of customer service AI company Fin and Autodesk Inc.’s $3.6 billion purchase of MaintainX Inc.
PitchBook’s report characterized the IPO landscape during this quarter as “rather mundane.” Notably, healthcare companies dominated the 18 venture-backed companies that went public; however, none were categorized as AI-focused, which Tarhuni emphasized is necessary for enhancing market liquidity. The past three years have seen a decreasing total number of new listings compared to the numbers already achieved in 2026 through September.
AI Giants Delay IPOs Amid Speculation
Neither OpenAI nor Anthropic has entered the public market yet. Reports suggest that OpenAI has opted out of pursuing an IPO this year, while Anthropic has postponed its offering until November, despite previously targeting an earlier date. PitchBook’s exit model estimates an 86% chance for Anthropic to go public within a year, in contrast to OpenAI’s comparatively modest 12% likelihood.
The private sector remains crowded, with the number of startups valued at $1 billion or more reaching a historic high of 992 by the end of September, holding a combined worth of $5.7 trillion. This year has seen 179 new unicorns created, a number that surpasses all years except for 2021 in terms of IPO activity.
Companies that do make sales are frequently settling for amounts significantly lower than their last private valuations. For example, Bending Spoons SpA acquired Airtable Inc. for $1.3 billion, down from an earlier valuation of $11.7 billion. Its expected acquisition of workplace collaboration platform Miro is also predicted to close at a valuation of $1.4 billion, down from a previous Series C funding round valuation of $17.5 billion.
On the fundraising front, U.S. venture firms have amassed $108.5 billion across 699 funds thus far this year, surpassing the total raised for the entirety of 2025 by nearly 39%. The majority of this capital—78%—has been captured by megafunds with $500 million or more, despite representing only 6% of all new funds. Notably, Andreessen Horowitz alone raised $23.8 billion through its recent funds.
Conversely, the number of emerging firms successfully closing funds this year stands at just 211, a drop from 927 in 2022, with first-time funds bringing in only $4.9 billion across 81 different vehicles. Bobby Franklin, president and CEO of the National Venture Capital Association, remarked that the vibrancy of AI innovation could mask the mounting challenges present within the fundraising landscape. He stressed the importance of sustaining a diverse and competitive investor base for ensuring the nation’s continued leadership in innovation.
Tarhuni concludes that while 2026’s figures may appear prosperous on the surface, the disparity in liquidity will have significant implications heading into 2027.
