"I thought this story was dead wrong. They already have a partnership. They didn't need to do this deal," Cramer said on CNBC's "Squawk on the Street." "I'm just saying that [Altera's] stock was up for a very long time and I knew that it didn't make sense."
News of a possible acquisition move between the two companies first broke in March, and led to Altera's stock rising 28 percent. The tech company opened Thursday trading down more than 7 percent before regaining some ground, while Intel's stock dipped about 2 percent.
The two companies have not talked in more than a week, according to sources close to the situation. They also said that Intel did make an offer to Altera in the low $50-per-share range.
Altera and Intel did not immediately respond to a request for comment from CNBC.
Cramer added that a deal between semiconductor company Broadcom and Intel would have made sense. "I always thought it was ; I didn't think it was Altera," he said. "They tried to talk in the 1990s and the deal failed."
Broadcom's stock was up about 1.8 percent in midmorning trading.
