AI Investment Expands by 75.6% in First Half of 2025, Despite Challenges in Venture Capital Fundraising
In the first half of 2025, global venture capital (VC) investment in artificial intelligence (AI) startups reached an unprecedented $126 billion, marking a significant increase compared to previous years.
According to PitchBook data cited by Axios, AI startups received approximately 53% of all global VC dollars during this period, a substantial rise from the 29% share in H1 2025. This proportion represents a dramatic acceleration, with AI-related investments accounting for just 26% of U.S. VC funding in 2023, rising to 45% in 2024, and surging to 71% in Q1 2025 alone.
Notable highlights in Q1 2025 include the historic $40 billion funding round by AI behemoth OpenAI, and an estimated $73 billion raised by AI startups globally. In the U.S., AI-related startups received around $80 billion in Q1 2025, capturing 57.9% of global VC funding during the quarter.
This trend reflects a strategic focus on AI technologies by investors, partly driven by major deals like OpenAI’s and a broader "AI FOMO" phenomenon where investors aggressively back AI ventures to avoid missing the potential gains in this transformational technology.
The funding for startups in the first half of 2025 was highly concentrated in the IT sector, with the Bay Area accounting for nearly 70% of all VC investment. AI startups comprised 29% of all startups funded, indicating increased venture interest in this sector.
In the U.S., AI defense tech startup Shield AI raised $240 million in a Series F round in Q1 of 2025, while SandboxAQ closed a $450 million Series E round in Q2. Anysphere, which introduced coding assistant Cursor in January, has sold a 7.25% equity stake for $105 million and may sell more at more than $10 billion.
Success stories include Cursor, Perplexity, Synthesia, ElevenLabs, and others amassing tens or hundreds of millions of dollars in annual recurring revenue. It has been reported that Anysphere has nearly $200 million of its annual recurring revenue.
