Nvidia has poured $2 billion into Synopsys, taking a major equity stake in one of the world’s most influential chip-design software makers as part of an expanded engineering and design partnership. The tech giant bought the shares at $414.79 apiece, just below Synopsys’ previous closing price of $418.01, the companies said on Monday.
The move triggered an immediate market reaction, sending Synopsys shares soaring about 8 percent in pre-market trading. The rally offered a sharp rebound for a stock that had slid nearly 14 percent year-to-date. Nvidia shares dipped slightly ahead of the opening bell, though the company remains the world’s most valuable publicly traded firm.
The investment marks the latest in a growing list of strategic bets Nvidia has placed across the AI supply chain. It has backed OpenAI, pumped capital into data-center operator CoreWeave, and even pledged $5 billion to Intel, a long-time rival, in a joint effort to co-develop chips for PCs and data-center infrastructure. These increasingly intertwined deals have stirred unease among analysts and regulators who warn that Nvidia’s investments risk creating circular financial loops—boosting the valuations of its partners and funneling capital to customers who then purchase more Nvidia hardware.
Synopsys, a cornerstone of the semiconductor design world, provides the software and services that underpin the creation of electronic components used across the industry. By strengthening its ties with Synopsys, Nvidia is doubling down on the upstream technologies that shape the next generation of chips, tightening its grip on the ecosystem powering the acceleration of artificial intelligence.
