Ambiq Micro (NYSE: AMBQ) made a splash on July 30, 2025, when its IPO priced at $24 per share and promptly nearly doubled on its first day of trading, hitting highs around $47.
More than just a breakout, this debut shows how investors are enthusiastic for ultra–low‑power chip makers targeting the booming edge AI market.
Ambiq sold 4.6 million shares, including the full exercise of the underwriters’ overallotment, raising roughly $96 to $110 million, and giving it an initial valuation of around $700 million.
Founded in 2010 and headquartered in Austin, Texas, Ambiq has carved out a niche by designing chips that consume two to five times less power than conventional alternatives, thanks to its proprietary Sub-threshold Power Optimized Technology (SPOT) platform.
By the end of 2024, it had shipped over 42 million units, with more than 40% supporting AI workloads, like fitness trackers, smartwatches, and IoT health sensors. The company’s existing installed base stands at an impressive 270 million devices.
Financially, Ambiq reported $76.1 million in revenue for 2024, an increase over the previous year’s $65.5 million, while trimming its net loss from $50.3 million in 2023 to $39.7 million.
In Q1 2025, it posted $15.7 million in sales and a net loss of $8.3 million, narrowing slightly from the year before.
Ambiq’s IPO racked up loads of attention not only for its valuation but because it’s backed by Arm Holdings, part of SoftBank Group, and top venture firms like Kleiner Perkins and EDB Investments, which lent it strong credibility.
The company used the IPO proceeds to fund expansion of its global engineering teams and accelerate product development, positioning itself to move beyond wearables into larger, power-sensitive applications such as AI data centers and automotive systems.
Ambiq’s first trading day was sort of a bumpy ride, as volatility sent regulators halting trading twice, but investors clearly responded to its long-term potential in edge AI.
The upside in its stock was driven by both enthusiasm for its power-efficient chipset technology and its position within a rapidly growing edge-AI market forecasted to jump from $13.9 billion in 2025 to $22.6 billion by 2028.
Of course, risks will not magically disappear: Ambiq is still loss-making, its revenue comes from a concentrated customer base, and it lacks long-term contracts, meaning that any order reduction could significantly impact future results.
But of course, its energy-efficient approach is increasingly relevant amid mounting concerns over AI’s rising power demands.
In the grand scheme, Ambiq Micro’s IPO feels like a calculated bet on the future of computing at the edge, where lower power does not mean lower intelligence.
For investors tracking small-cap semiconductors, Ambiq is a compelling mix of high-growth potential, clean ESG-related differentiation, and early momentum in a fast-evolving space.
