The paradox landed on my desk like a piece of shattered silicon: Bank of America lowered Onsemi's target price while the company reported a surge in quarterly profits. On the surface, the move seems irrational—a downgrade in the face of operational strength. But for those of us who map the flows between macro liquidity and digital asset infrastructure, the signal is unmistakable. The semiconductor industry's inventory cycle is turning, and the ripple effects will hit Bitcoin mining hardware, GPU availability, and the cost of securing proof-of-work networks before the end of the year. We map the flows, but the ocean remains unmapped—yet the currents are shifting.
Onsemi is not a household name in crypto. It does not manufacture ASICs for Bitcoin or GPUs for Ethereum. But it is the quiet backbone of the power electronics that drive mining rigs, data center PSUs, and high-voltage infrastructure for AI clusters that also host blockchain nodes. As a cross-border payment researcher, I have spent the past eighteen years tracing the arteries of global supply chains, and I have learned that the health of a single power semiconductor company often predicts the cost of moving digital value across borders. The Onsemi story is a microcosm of a larger macro reality: the post-pandemic chip glut is finally giving way to a structural oversupply in power devices, and the crypto mining industry will be a major beneficiary—and a victim—of this transition.
Context: The Power Semiconductor Landscape
Onsemi is an Integrated Device Manufacturer (IDM) specializing in power semiconductors: MOSFETs, IGBTs, silicon carbide (SiC) devices, and analog chips. Unlike the logic fab giants (TSMC, Samsung) that chase nanometer nodes, Onsemi operates in the mature-node sweet spot—200mm and 300mm wafers with specialized processes for high-voltage, high-reliability applications. Its revenue is roughly 50% automotive, 25-30% industrial, 5-10% cloud/AI data center, and the remainder in communications and consumer. The company has been aggressively investing in SiC vertical integration, acquiring GT Advanced Technologies to internalize substrate production, and building a 300mm power fab in East Fishkill, New York, backed by up to $1.5 billion in CHIPS Act subsidies.
Why does this matter for crypto? Because every Bitcoin mining rig—whether an Antminer S19 or a Whatsminer M50—contains dozens of power MOSFETs and voltage regulators that manage the high-current draw from the PSU to the hash boards. The same goes for GPU mining rigs, which rely on multi-phase power stages. The cost and availability of these components directly influence the price of mining hardware and, by extension, the hash rate growth trajectory. When Onsemi's capacity is constrained, mining rig production slows; when Onsemi faces oversupply, component prices drop, and manufacturers like Bitmain and MicroBT can pass savings to miners.
Core: The Inventory Cycle and Its Implications for Mining Hardware
Based on my audit experience with payment infrastructure providers, I have seen how inventory cycles in semiconductor supply chains preced shifts in hardware pricing by two to three quarters. Onsemi's current situation is a textbook case of a cyclical downturn masked by a profit spike. The company's gross margin peaked above 49% in 2022, driven by the post-pandemic shortage and the EV boom. By 2024, gross margin had fallen to the mid-45% range, partly due to capacity underutilization and depreciation from new fabs. Bank of America's target price cut likely reflects an expectation that margins will continue to compress as the auto and industrial sectors complete their destocking—and as a flood of new SiC capacity from competitors like Infineon, STMicroelectronics, and Chinese suppliers drives down average selling prices.
For the crypto mining industry, this is a double-edged sword. On the one hand, lower power semiconductor prices mean cheaper BOM (bill of materials) for mining rig manufacturers. A 10% reduction in the cost of power components can translate into a 3-5% reduction in the retail price of a new ASIC miner. For miners operating on thin margins in a post-halving environment, every dollar counts. On the other hand, the inventory destocking also signals weak demand from the automotive sector, which is a leading indicator for global economic growth. If the auto industry is cutting orders, it suggests that consumer spending is faltering, which could depress Bitcoin demand and put downward pressure on price. The macro signal from Onsemi's downgrade is therefore ambiguous: cheaper hardware but potentially weaker coin price.
Let me break down the technical details. Onsemi's SiC MOSFETs are critical for high-efficiency power conversion in the 800V to 1,200V range—exactly the voltage levels used in the PSUs of high-performance mining rigs. The shift from planar to trench-gate SiC structures improves switching efficiency and reduces thermal losses, which is why miners are moving toward immersion cooling and higher-density power supplies. However, the industry-wide price decline in SiC devices is accelerating. According to public data, SiC MOSFET prices have fallen 20-30% year-over-year in 2025, driven by Chinese competitors like BYD Semiconductor and Starpower. This is good news for miners: the cost of the most efficient power stage is dropping, enabling higher hash rates per watt. But it also means that Onsemi's margin compression is not temporary—it is a structural shift that will force the company to rely on volume growth rather than pricing power.
From a capacity perspective, Onsemi's 300mm wafer fab in East Fishkill is a strategic asset. Moving from 200mm to 300mm wafers reduces die cost by roughly 30% for power devices, giving Onsemi a cost advantage over rivals stuck on 200mm. The CHIPS Act subsidy helps offset the $2-3 billion capital expenditure, but the depreciation will suppress free cash flow for the next three years. For crypto miners, this means that Onsemi will be highly motivated to keep its fabs loaded with orders, even if it means offering volume discounts to large customers like Bitmain. In the current market, I expect to see more aggressive pricing for power modules used in mining rigs, potentially lowering the cost of new-generation miners by 5-10% in the second half of 2026.
Contrarian: The Decoupling Thesis
The conventional narrative is that the semiconductor cycle is a lagging indicator for crypto—miners only care about Bitcoin price and hash rate. I take the opposite view. The decoupling between hardware cost and crypto asset price is exactly where the risk lies. If Onsemi's inventory destocking is a sign of a broader economic slowdown, then Bitcoin's correlation with traditional risk assets could reassert itself, dragging prices down even as mining hardware becomes cheaper. The market is currently pricing in a soft landing, but the semiconductor industry is voting with its order books: industrial and automotive customers are not placing long-term contracts, preferring spot buys. That is a bearish signal for economic momentum.
However, there is a hidden angle: the AI data center segment is growing at a high double-digit rate, and Onsemi's power devices are essential for the 48V and 800V architectures used in Nvidia's GPU clusters. As AI inference moves to the edge, the demand for efficient power conversion will only increase. This is a structural demand driver that is largely independent of the auto/industrial cycle. If Onsemi can pivot its capacity toward AI and cloud, it may offset the mining/automotive weakness. But that requires time—and time is something miners do not have when they are making capital allocation decisions for the next 18 months.
Takeaway: Positioning for the Cycle
I see the pattern before it becomes a trend. The Onsemi target price cut is not a one-off event; it is the first domino in a chain of re-ratings for power semiconductor companies. For crypto miners, the implication is clear: the next six months will offer a window of opportunity to procure mining hardware at lower costs, but the macro headwind from weakening industrial demand could compress Bitcoin's price. The savvy move is to hedge your exposure—lock in hardware prices with long-term contracts while ensuring you have enough liquidity to weather a potential downturn. The chip inventory cycle is a mirror of the broader liquidity cycle, and right now, that mirror shows a murky reflection. Between the wafer and the wallet, there is a void. Fill it with data, not hope.
