Nvidia (NASDAQ:NVDA [https://seekingalpha.com/symbol/NVDA]) shares hit a new record on Tuesday, rising nearly 3% and making the chipmaker the first company to hit a $4.53 trillion market cap.

Shares rose 2.6% on Tuesday to close at $186.58 on September 30. Nvidia has raced through market cap milestones in recent years, crossing $3 trillion in June 2024 and $4 trillion in July 2025 as demand for its AI chips continues to surge.

Market caps of other megacap tech peers stand at: Palantir Technologies (PLTR [https://seekingalpha.com/symbol/PLTR]) $432.58B; Oracle (ORCL [https://seekingalpha.com/symbol/ORCL]) $801.76B; Broadcom (AVGO [https://seekingalpha.com/symbol/AVGO]) $1.56T; Apple (AAPL [https://seekingalpha.com/symbol/AAPL]) $3.78T; and Advanced Micro Devices (AMD [https://seekingalpha.com/symbol/AMD]) $262.56B.

Nvidia (NASDAQ:NVDA [https://seekingalpha.com/symbol/NVDA]) has advanced 39% year-to-date, boosted by a string of artificial intelligence infrastructure deals. Nvidia recently struck a landmark partnership with Microsoft-backed (MSFT [https://seekingalpha.com/symbol/MSFT]) OpenAI, committing up to $100 billion to build AI infrastructure capable of supporting at least 10 gigawatts of compute power.

OpenAI later unveiled plans with Oracle (ORCL [https://seekingalpha.com/symbol/ORCL]) to build five massive new data centers, designed to house hundreds of thousands of GPUs. OpenAI isn’t the only one scaling up—Meta (META [https://seekingalpha.com/symbol/META]), Google (GOOG [https://seekingalpha.com/symbol/GOOG]) (GOOGL [https://seekingalpha.com/symbol/GOOGL]), and other tech giants are also pouring heavily into infrastructure. On Tuesday, CoreWeave (CRWV [https://seekingalpha.com/symbol/CRWV]), a cloud provider backed by Nvidia, announced a $14.2 billion deal to deliver AI infrastructure services to Meta.
