▶Altimeter employs a highly concentrated investment strategy, deliberately avoiding diversification to chase outlier returns by making large bets on a few companies believed to be on a 'power law' trajectory.Apr 2026

▶The firm is willing to write very large checks, ranging from $15-$25 million for Series A rounds to over $250 million for growth-stage companies, positioning it as a major capital provider for top-tier private companies.Apr 2026

▶Altimeter has made a significant, firm-defining investment in OpenAI, participating in a recent $40 billion funding round and considering it the largest investment in the firm's history.Apr–May 2026

▶The firm operates a crossover investment model where insights from public market holdings (e.g., NVIDIA) inform private investments (e.g., CoreWeave), and long-standing relationships with public companies (e.g., Snowflake) generate proprietary deal flow (e.g., Smuha).Apr 2026

▶There is a potential contradiction regarding Altimeter's single largest investment. One source claims it is Anduril by position size, while another states OpenAI is the largest investment in the firm's history, suggesting a possible difference between current market value and total capital deployed.Apr 2026

▶The firm's investment focus appears split between software/AI (OpenAI, Snowflake, CoreWeave) and 'hard tech' sectors like aerospace, defense, and manufacturing (Anduril, Hadrian, Vulcan Elements), presenting a dual-pronged rather than a single-sector thesis.

▶There's a contrast between the internal 2021 prediction of a difficult fundraising environment for Altimeter's own funds and the external observation that the firm has continued to deploy massive amounts of capital into its portfolio companies, suggesting a divergence between capital raising and capital deployment conditions.Apr–May 2026
