US AI Chipmaker Ambiq Lists on SGX, Deepens Singapore R&D for Edge AI
Source: The Business Times
US semiconductor company Ambiq Micro has commenced trading on the Singapore Exchange Mainboard in a secondary listing by way of introduction, marking the first sizeable global fabless chip design company to list on SGX. The Austin-based firm, known for its ultra-low-power chips powering edge AI devices from wearables to smart infrastructure, also runs a multi-year R&D programme in Singapore supported by the Economic Development Board.
Singapore's semiconductor ecosystem got a vote of confidence this week with a listing that brings together two of the fastest-growing areas in technology — AI and chips. Ambiq Micro, the US-based designer of ultra-low-power semiconductor solutions, began trading on the SGX Mainboard on July 30 under the ticker AMQ, and the move signals something bigger than just another dual listing.
Ambiq's debut on SGX is a secondary listing by way of introduction — no new shares were offered and no fresh capital was raised in Singapore. The company maintains its primary listing on the New York Stock Exchange, where it went public in July 2025 at US4 per share. Its SGX-listed shares opened at S3.74. The listing comes as Ambiq's NYSE stock has faced downward pressure amid a broader sell-off in semiconductor equities and investor jitters around AI capital expenditure returns.
What makes this listing worth watching isn't the trading mechanics — though those are interesting too, with SGX quoting the stock in Singapore dollars and offering smaller board lot sizes of 10 shares for retail accessibility. The real story is the operational commitment behind it. Ambiq runs a multi-year R&D programme in Singapore supported by the Economic Development Board, and earlier this year announced plans to hire 30 specialised tech roles in the city-state for integrated circuit design and next-generation edge AI development.
The company's proprietary Sub-threshold Power Optimized Technology (SPOT) platform is at the centre of this push. It dramatically reduces power consumption for AI at the edge — think wearables, smart infrastructure sensors, and IoT devices that need to run AI models without draining batteries or relying on cloud connectivity. As Pol de Win, SGX Group's head of global sales and origination, put it: "As AI moves out of the data centre and onto everyday devices, a Singapore listing elevates Ambiq's profile with Asian investors." The cross-border trading mechanism also lets investors convert and transfer shares between SGX and NYSE on a scripless basis via CDP.
Why it matters for Singapore: Ambiq's SGX listing and expanding R&D presence reinforces Singapore's position as a destination for deep-tech semiconductor companies, not just fintech and software startups. The EDB-backed R&D programme and the specialised IC design roles being created here contribute directly to building Singapore's hardware talent pipeline — a layer of the AI stack that's often overshadowed by software and services in local coverage. As the global AI build-out pushes compute out of data centres and into edge devices, the chip design expertise being anchored here today will matter more tomorrow.
