U.S. chipmaker Intel (INTC.O) agreed to buy Israeli driverless car-technology firm Mobileye (MBLY.N) for $15.3 billion on Monday, positioning itself for a dominant role in the fast-moving autonomous-driving sector.

The $63.54-per-share cash deal marks the largest purchase of a company solely focused on the self-driving sector and could significantly alter the competitive landscape among key technology and systems suppliers, including chipmakers Nvidia Corp (NVDA.O) and Qualcomm Inc (QCOM.O) and systems integrator Delphi Automotive PLC (DLPH.N).

Mobileye's shares jumped 30 percent to $61.30 in late morning U.S. trading, while Intel's shares were down 2 percent. Shares of Delphi, which has partnerships with both companies, were up 3 percent.

The deal underscores the expanding alliances between automakers and their suppliers as they race to develop self-driving cars, a concept that once seemed a science-fiction dream but is drawing closer to reality.

While Intel is known for hardware chips and Mobileye for collision detection and mapping software, the merger promises to create an expanded portfolio of technologies needed for driverless vehicles. It also strengthens Intel's position in the sector against rival chipmakers Nvidia and Qualcomm.

The Intel-Mobileye portfolio includes cameras, sensor chips, in-car networking, roadway mapping, machine learning, cloud software and data fusion and management.
