Celente was born in The Bronx, New York City, New York. He had early political experience running a mayoral campaign in Yonkers, New York and served as executive assistant to the secretary of the New York State Senate, which Celente called the worst job he ever had. From 1973 to 1979 Celente traveled between Chicago and Washington D.C. as a government affairs specialist. In 1980 Celente founded The Trends Research Institute (at first called the Socio-Economic Research Institute of America), now located in Kingston, New York, publisher of the Trends Journal which forecasts and analyzes business, socioeconomic, political and other trends.

His forecasts since 1993 have included predictions about terrorism, economic collapses and war. More recent forecasts involve fascism in the United States, food riots and tax revolts. Celente has long predicted global anti-Americanism, a failing economy and immigration woes in the U.S. In December 2007 Celente wrote, "Failing banks, busted brokerages, toppled corporate giants, bankrupt cities, states in default, foreign creditors cashing out of US securities ... whatever the spark, the stage is set for panic in the streets" and "Just as the Twin Towers collapsed from the top down, so too will the U.S. economy ... when the giant firms fall, they’ll crush the man on the street." He has also predicted tax revolts. In November 2008 Celente appeared on Fox Business Network and predicted economic depression, tax rebellions and food riots in the United States by 2012. Celente also predicted an "economic 9/11" and a "panic of 2008."

In 2009 Celente predicted turmoil which he described as "Obamageddon" and he was a popular guest on conservative cable-TV shows such as Fox News Sunday and Glenn Beck's television program. In April 2009 Celente wrote, "Wall Street controls our financial lives; the media manipulates our minds. These systems cannot be changed from within. There is no alternative. Without a revolution, these institutions will bankrupt the country, keep fighting failed wars, start new ones, and hold us in perpetual intellectual subjugation." He appeared on the Glenn Beck show and criticized the U.S. stimulus plan of 2009, calling government controlled capitalism "fascism" and saying shopping malls in the U.S. would become "ghost malls." Celente has said, "smaller communities, the smaller groups, the smaller states, the more self-sustaining communities, will 'weather the crisis in style' as big cities and hypertrophic suburbias descend into misery and conflict," and forecasts "a downsizing of America."

Predictions

2009

"The Crash of '09 was as dramatic as the crash of '29. The New Depression had begun." (Trends Journal, Summer 2008, pg. 12)

2010

Some areas of the U.S. are experiencing resurgences in real estate values due to highly localized factors, and some investors profit from this. However, the rises will almost all stop and reverse with time, and the overall national trend in real estate values is downward. (T.J. Summer 08, pg. 8)

Ghost malls have become a common sight across America. Especially hard-hit are big chain stores (Sears, Home Depot, etc.). (T.J. Summer 08, pg. 8)

2011

Developers have begun rehabbing some of the ghost malls for more productive uses. (T.J. Summer 08, pg. 9)

2012

The economic policies of the U.S. government over the past few years have failed to fix America's fundamental problems and have merely papered over them and in fact made them worse. By 2012, the "American Empire" is collapsing. In the U.S., basic staple goods like quality food and water are too expensive for most people to afford,(T.J. Summer 08, pg. 1) and "food riots" happen across the country (T.J. Summer 09, pg.1). Major American cities look like disaster zones, and mass homelessness exists across the country. Crime is rampant, with much of it being directed at the rich. (T.J. Summer 08, pg. 1) Kidnappings and ransomings of rich people are on the rise. Average people fed up with big government, high taxes and out-of-control spending join tax revolts. (T.J. Summer 09, pg. 1) The world is also experiencing major environmental problems and "the blackest of plagues." The global financial system has also "melted down" and the situation is very bad outside the U.S.(T.J. Summer 08, pg. 1) The advanced industrial economies collapse first, and their sagging consumer spending drags down the export-based economies of emerging economies next.(T.J. Summer 09, pg. 2) The economy is as bad as it was during the Great Depression in many ways. In spite of all this, the U.S. government, power elites, and mainstream media continue to insist that the fundamentals of the world economy are sound, and that official policies can lead to a recovery. A growing number of average people, however, doubt this. (T.J. Summer 08, pg. 1)

While the Mayan and Hopi prophecies of global destruction do not come to pass, 2012 is indeed a watershed year that sees the death of an ailing and unsustainable global economic system and lifestyle and its replacement with something better. (T.J. Summer 08, pg. 2)

By 2012, Obama is viewed by most as a stale president who sold himself as a fresh, visionary candidate in 2008 and instead proved to be a servant of the big corporations and the military-industrial complex like his predecessors.(T.J. Summer 09, pg. 5) His economic policies only delayed disaster and in fact have made the situation worse: Expansionary monetary policy and the various government bailouts and stimulus programs create a "Bailout Bubble" that invariably bursts in a cataclysm for the U.S. and world economy.(T.J. Summer 09, pg. 11) Obama blames other factors for this and might have even tried to start a war by 2012 to distract attention from the domestic misery.(T.J. Summer 09, pg. 12) Obama's foreign policy has also failed to accomplish anything significant on the world stage, and Pakistan is a mess and the Afghan war continues to drag on without hope of conclusion.(T.J. Summer 09, pg. 12)

In the 2012 U.S. elections, online news sites, bloggers and independent journalists wield as much influence on voters as mainstream media outlets (TV, cable, magazines, newspapers) for the first time. This breaks the corporate and moneyed stranglehold on American politics and allows a third party to attain nation-level recognition. (T.J. Summer 08, pg. 5)

Broad future trends

Americans will adapt to lower standards of living and will travel less, both on a daily basis and for vacations. Higher fuel costs, advances in telecommuting and an aging American population will push many more people to work from home or close to home. Walking-distance communities will be constructed and will become popular. (T.J. Summer 08, pg. 7)

Geographically isolated resort destinations like Las Vegas will wither due to higher fuel costs, lower American incomes and increased overseas competition while vacation spots closer to population centers will revive. (T.J. Summer 08, pg. 9)

Government-run lotteries, on the other hand, will thrive. (T.J. Summer 08, pg. 9)

In America and to a lesser extent overseas, consumer spending habits will be motivated out of fear and escapism. Businesses that capitalize upon this will succeed. (T.J. Summer 09, pg. 24)
