The show in Orlando, which will run through February 9, features over 300 exhibitions from leading financial institutions.
Russia's top trade representative to the U.S. said national companies face a major challenge in attracting American investors.
"There is now quite a vigorous battle for American investment. Russia's active competitors in this area are, primarily, China, Brazil, India, and Eastern European countries. This is why we highly value the chance to make presentations to an audience of several thousand business people at this forum," Andrei Dolgoruky told RIA Novosti in an interview.
Investment opportunities in Russia, whose stock market remains strong amid difficulties abroad, will be presented at RIA Novosti pavilions and the Russian Chamber of Commerce in the United States. RIA Novosti is also an official media partner of the forum, for the second year running.
Razan, an investor from Pakistan attending the show, said: "I get a good overall view of what's going on in the investment environment. Recently I sold all of my holdings in Pakistan because of the political imbalance and I am now looking into other areas of prosperous investments, including very interesting ones in Russia."
The show, being held at Gaylord Palms Resort in Kissimmee outside Orlando, allows investors and potential investors to meet directly with company representatives, seek market advice, attend seminars given by investment strategists, and meet others looking to invest in equities, bonds, real estate, oil and gas, precious metals, and other sectors.
The forum's chairman, Charles Githler, said: "This is our 30th year of holding this annual show in Orlando and we've recently surpassed the 50,000-member mark. We've launched our new site (www.moneyshow.com), marking yet another milestone in our continuing quest to bring the best investment experts to investors around the world."
Investment companies including Germany's Deutsche Bank and U.S. companies Wachovia Securities and VectorVest are represented at the show.
The vice president of event organizer Intershow, Greg Huffman, said: "We have 14,500 people registered for the show here in Orlando, though we're expecting to bring in over 15,000 participants over the next two days."
"The Orlando World Money Show is celebrating its 30th anniversary, we organized the fourth World Money Show in London last December, and we're opening a new World Money Show in March 2009 in Hong Kong," he added.
