From OpenAI to Groq, 6 VC Trends That Captured AI Funding Gold Rush of 2025

The year gone by was stellar for the AI ecosystem. In 2025, venture capital flowed like a river for many late-stage and application-led AI companies, as AI reshaped the entire tech investment landscape.

According to Crunchbase, global investment in AI reached $202.3 billion by Q3 2025, a 75% year-on-year increase.  AI alone accounted for nearly half of all global venture funding in 2025, concentrating capital at a scale rarely seen in private markets. 

Here are some of the AI funding highlights from 2025:

OpenAI Raised Whopping $40 Bn 

While reports hinted at OpenAI pursuing an IPO, the AI pioneer, in 2025, raised unprecedented capital, making it the largest private tech fundraising event in US history.

In April 2025, OpenAI closed a $40 billion financing fund led by Softbank, with $10 billion in mid-April and an additional $30 billion in December. 

Following the deal, OpenAI’s valuation continued to climb through secondary transactions, with employee and insider share sales implying a valuation near $500 billion by October.

By December 2025, the company was reported to be in preliminary talks to raise to $100 billion more at a valuation in the range of $750–830 billion. 

Anthropic: High Funding, Higher Valuation 

OpenAI’s fiercest private competitor, Anthropic, projected the discipline of a public-market company, even as it played down near-term IPO plans. Executives told Financial Times that discussions about a public listing remained preliminary, with no fixed timeline or decision in place.

In March 2025, it raised $3.5 billion in a Series E round at a $61.5 billion post-money valuation, led by Lightspeed Venture Partners and with participation from Bessemer, Cisco, Fidelity, and others, cementing investors’ faith in its Claude models.

That momentum accelerated with a $13-billion Series F haul in September, lifting its valuation to about $183 billion. The round was co-led by ICONIQ Capital, Fidelity and Lightspeed, among a broad syndicate of institutional backers.

External analyses indicated that Anthropic was on track to reach profitability years ahead of rivals like OpenAI, with forecasts suggesting a break-even point around 2028 as revenue growth from enterprise customers surged and cost efficiency improved. 

Reports in December 2025 indicated that Anthropic is in talks for a new private funding round that could value it at over $300 billion. 

Databricks: More Late-Stage Capital

Databricks CEO Ali Ghodsi has been vocal about avoiding the public markets when conditions aren’t favourable, famously saying it was “dumb to IPO” in 2024 and opting instead to tap private capital while preparing the business for eventual listing.

Databricks sustained strong investor demand through 2025. 

In August, the company cashed in a $1 billion Series K investment at a valuation of roughly $100 billion. Later, in December, Databricks announced a Series L funding round exceeding $4 billion. 

This huge late-stage raise underscored sustained investor appetite as demand for AI-driven data platforms continued to accelerate. 

With an annual revenue run rate of about $4.8 billion, positive cash flow, and a valuation of roughly $134 billion, the company is increasingly challenging conventional wisdom around when—or even whether—high-growth technology firms need to go public.

Anysphere: Now Valued at ~$30 Bn

Cursor’s parent company, Anysphere, had a breakout funding year as its AI-driven developer tool quickly became one of the most popular platforms for software engineers. 

Built around the AI coding assistant Cursor, the company’s growth attracted escalating venture capital interest throughout the year, beginning with a $900 million Series C round in July led by Thrive Capital with Andreessen Horowitz, Accel, and DST Global at a roughly $9.9 billion valuation.

That momentum continued into late 2025, when Anysphere closed a $2.3 billion Series D financing, with participation from heavyweight strategic backers including NVIDIA and Google, that lifted its valuation to about $29.3 billion. 

Meta’s Minority Stake in Scale AI

Scale AI, the leading data infrastructure provider for training and evaluating AI models, remained one of 2025’s most capital-intensive private tech stories outside of core model builders when Meta Platforms agreed to invest $14.3 billion in June 2025 for a 49% stake, valuing the company at around $29 billion and expanding its commercial collaboration with the tech giant.

A key component of the deal was Scale co-founder and CEO Alexandr Wang transitioning to Meta to lead its Superintelligence Labs, a bespoke research unit focused on next-generation AI capabilities, while remaining on Scale’s board—a move that underpinned much of Meta’s strategic rationale for the investment.

Europe’s AI Giants: Lovable & Mistral Raise Big Money

As demand for vibe coding platforms surged in 2025, the Stockholm-based startup Lovable stocked up on cash. In July, it raised a $200 million Series A led round by Accel at a $1.8 billion valuation, making it one of Europe’s fastest-growing unicorns just months after launch.

Building on that momentum, in December, the company secured a $330 million Series B round at a valuation of $6.6 billion, led by CapitalG and Menlo Ventures, and with participation from Khosla Ventures, Salesforce Ventures, and Databricks Ventures. 

However, the Swedish startup stands second in the list of most valuable AI startups of Europe, with Mistral taking the crown. The French foundational AI model maker closed a €1.7 billion (≈$2 billion) Series C funding round at an €11.7 billion valuation in September. 

The round was led by Dutch semiconductor equipment giant ASML, which invested about €1.3 billion and became Mistral’s largest shareholder with an 11% stake, alongside continued participation from existing backers including DST Global, Andreessen Horowitz, Bpifrance, General Catalyst, Index Ventures, Lightspeed, and NVIDIA.

OpenAI Alumni Raised Big Money 

OpenAI alumni continued to shape the 2025 AI funding landscape, with SSI and Thinking Machines Lab emerging as among the most closely watched new ventures.

Safe Superintelligence Inc. (SSI), co-founded by OpenAI’s former chief scientist Ilya Sutskever with Daniel Gross and Daniel Levy, raised in $2 billion in March at a $32 billion valuation, despite having no product or revenue yet, attracting involvement from Greenoaks as lead investor and participation from Lightspeed, Andreessen Horowitz, Alphabet, and NVIDIA.

Alongside SSI, Thinking Machines Lab, founded in early 2025 by former OpenAI CTO Mira Murati and staffed with researchers from OpenAI, Meta and other leading AI groups, closed a massive ~$2 billion seed round in July led by Andreessen Horowitz at a $12 billion valuation. 

Later in the year, the company unveiled its first product, Tinker, to help researchers and developers access compute easily for ML and AI research. 

AI Hardware Companies: Cerebras Billion Dollar Funding, Groq Joins NVIDIA

Shortly after withdrawing its IPO registration in October 2025, chipmaker Cerebras Systems raised $1.1 billion in a Series G financing at an $8.1 billion valuation in September 2025, led by Fidelity Management & Research and Atreides Management, with participation from Tiger Global, Valor Equity Partners. and 1789 Capital. 

This underscored continued private investor support for its wafer-scale AI compute technology and expansion of cloud and enterprise deployments. 

Groq, another prominent AI chip startup, focused on inference architectures and strengthened its financial footing in 2025 with a major funding round of approximately $750 million at a $6.9 billion valuation, reflecting growing demand for efficient inference hardware even as NVIDIA dominates training compute.

In December, the company entered a licensing and talent agreement with NVIDIA, under which NVIDIA licensed Groq’s inference technology and onboarded key executives, including founder Jonathan Ross and President Sunny Madra, while Groq continues to operate independently. The deal was reported to be worth up to roughly $20 billion.
