Onsemi Targets $213B AI Power Semiconductor Market
ON Semiconductor, also known as Onsemi, is targeting a $213 billion AI power semiconductor market by 2030. At its 16 September Investor Day, the company said power density could become the next major constraint for artificial intelligence data centres, replacing computing power and memory as the key infrastructure bottlenecks.
Onsemi expects AI data centre revenue to rise from about $500 million in 2026 to more than $2.5 billion by 2030. That implies annual growth of over 50%. The company is also targeting roughly $11 billion in total revenue by 2030, representing a 12–14% compound annual growth rate.
The potential acquisition of Synaptics could expand Onsemi’s total addressable market to more than $243 billion. Chief executive Hassane El-Khoury said AI systems may increase from around 60 kilowatts today to 200 kilowatts and potentially 1 megawatt, intensifying demand for efficient power management.
Onsemi introduced its GaNEXUS gallium-nitride platform and Embedded Power Platform, which use advanced materials and wafer-level integration to improve power efficiency and density. The company also highlighted continued demand from hyperscale customers and its existing silicon-carbide capabilities through GT Advanced Technologies.
The AI power semiconductor market gives Onsemi exposure to data-centre growth without directly competing with Nvidia or AMD in GPUs and processors. However, the projections are based on management guidance and Investor Day optimism. Traders should monitor execution, hyperscaler spending, acquisition progress and valuation for confirmation of the AI power semiconductor thesis.
Neutral
The direct cryptocurrency-market impact is neutral because the article concerns Onsemi’s semiconductor strategy rather than blockchain networks, digital-asset regulation or crypto-market liquidity. It may still have an indirect effect through the broader AI and technology trade.
In the short term, Onsemi’s forecast of more than 50% annual growth in AI data-centre revenue and a $213 billion addressable market could support positive sentiment in AI-related equities and semiconductor suppliers. Traders may view power management as a new infrastructure theme alongside GPUs, memory and networking. However, the announcement is based largely on management projections, so it is unlikely to create a direct catalyst for BTC, ETH or other major crypto assets.
The main risks are execution and valuation. If hyperscaler capital spending remains strong, successful GaN and embedded-power product launches, together with progress on the Synaptics acquisition, could improve confidence in the wider AI hardware cycle. Conversely, weaker data-centre spending, delays, integration problems or a disappointing earnings update could trigger a rotation out of AI-linked equities. Similar to past semiconductor Investor Day announcements, the initial reaction may be optimistic, while longer-term price performance will depend on orders, margins and delivered revenue.
For crypto traders, the key signal is broader risk appetite. Strong AI infrastructure demand could support technology-sector sentiment and speculative trading, while an AI spending slowdown could weigh on high-beta assets, including cryptocurrencies. Without a direct crypto catalyst, the expected effect remains neutral.
