(Updates sponsors, background on Gores)

Feb 22 (Reuters) - A blank-check firm backed by billionaire Alec Gores and investment bank Guggenheim Partners is looking to raise nearly $750 million through an initial public offering $(IPO.UK)$, a regulatory filing showed on Monday.

Gores Guggenheim, co-sponsored by Gores Group LLC and Guggenheim, said it plans to sell 75 million units composed of shares and warrants, priced at $10 per unit on the Nasdaq Capital Market.

Gores Guggenheim is the thirteenth special purpose acquisition company (SPAC) backed by Gores, who is among Wall Street's most prolific SPAC dealmakers and has raised billions of dollars through multiple blank-check vehicles so far.

Another Gores-backed SPAC, Gores Holdings VI Inc , earlier this month agreed to take 3D camera maker Matterport Inc public for $2.9 billion.

SPACs, or blank-check firms, are shell companies that raise funds through an IPO to take a private company public and have emerged as one of Wall Street's most favored investment vehicles in recent times. For the company going public, striking a deal with a SPAC is an alternative to a traditional IPO.

Deutsche Bank Securities, Citigroup and Morgan Stanley are the lead underwriters for the latest offering.
