Ambiq, InMobi Plan Major AI-Driven IPOs

Ambiq Micro Inc., an Austin-based semiconductor company specializing in ultra-low power chips for AI applications, is preparing to raise up to $85 million in its US IPO by offering 3.4 million shares at $22 to $25 each. The company's anticipated market capitalization is more than $412 million if the IPO is fully subscribed. Ambiq, backed by Arm Holdings, supplies chips used in over 270 million devices globally and is expanding beyond China due to geopolitical and pricing concerns. Separately, SoftBank-backed InMobi is planning an initial public offering in India targeting up to $1 billion and a valuation of $5-6 billion, though final terms have not been set. Both IPOs underscore heightened investor interest in AI and semiconductor technologies amid rising demand for energy-efficient solutions. The proceeds from Ambiq's IPO are intended for next-generation AI chip development and market expansion.
