American Philanthropic Donations

American philanthropists are among the top philanthropists in the world. America’s wealthiest people are also the most generous givers in the country. Despite the drop in billionaire fortunes in 2022, charitable donations by American philanthropists increased last year. As per Forbes, the 25 biggest donors on its list donated around $196 billion over their lifetimes through the end of 2022, up from $196 billion in 2021. The $27-billion rise in philanthropic donations in 2022 has surpassed the $20-billion gain in the last two years and sums more than what the top 25 philanthropists gave away in 2018.

According to the National Philanthropic Trust, Americans donated $499.33 billion in 2022. The corporate and foundation donations grew to $21.08 billion and $105.21 billion in 2022, respectively. Corporate giving increased 2.4% compared to 2021 and foundation giving increased 2.5% from 2021. While donation by bequest in 2022 was $45.6 billion. In 2022, the largest source of philanthropic activities in the US came from individuals, who donated $319.04 billion, representing 64% of total giving.

In 2022, the majority of the charitable dollars went to organizations serving in religion at 27%, human services at 14%, and education at 13%, among others. While there was double-digit growth in gifts for foundations.

American Philanthropists Who Have Pledged

American philanthropists have been donating billions for years now. In 2010, Warren Buffett, Bill Gates, and Melinda French Gates established The Giving Pledge. The purpose of The Giving Pledge was to gather philanthropists so they could pledge a large portion of their wealth to public service after their death. The idea was initially to gather ultra-wealthy people from the US, but The Giving Pledge saw interest from philanthropists around the world. Warren Buffett who is one of the richest billionaires in the world has pledged 99% of his wealth for donation. In his pledge letter, Warren Buffett says:

“First, my pledge: More than 99% of my wealth will go to philanthropy during my lifetime or at death. Measured by dollars, this commitment is large. In a comparative sense, though, many individuals give more to others every day.”

Buffett generates his wealth from his holding firm Berkshire Hathaway Inc. (NYSE:BRK-B). On June 22, Reuters reported that Buffett has donated another $4.64 billion of Berkshire Hathaway Inc. (NYSE:BRK-B) stock to five charities, including a donation to the Bill & Melinda Gates Foundation. Since 2006, Buffett has donated more than $51 billion through the giving of his Berkshire Hathaway Inc. (NYSE:BRK-B) shares. With Warren’s recent donation, he gave away 13.7 million of Berkshire Hathaway Inc.’s (NYSE:BRK-B) shares, of which 10.45 million shares were given to the Bill & Melinda Gates Foundation. Warren Buffett has contributed more than $39 billion of Berkshire Hathaway Inc.’s (NYSE:BRK-B) shares to the Bill & Melinda Gates Foundation overall.

Founder of Microsoft Corporation (NASDAQ:MSFT), Bill Gates is one of the biggest philanthropists in the US. Bill has made his fortune from Microsoft Corporation (NASDAQ:MSFT) and he has been donating through his foundation, the Bill & Melinda Gates Foundation. Gates established the foundation in 2000 and since then he has contributed billions to various non-profit and profit organizations. Bill Gates is investing in an Australian climate technology startup. On January 23, Bloomberg announced that Breakthrough Energy Ventures LLC, led by Microsoft Corporation’s (NASDAQ:MSFT) founder, and Andrew Forrest’s Harvest Road Group participated in a $12 million Phase 2 seed funding round for Rumin8 Pty.

Bill through his foundation contributes to various organizations that are doing the job for the betterment of society. In October 2023, the Bill & Melinda Gates Foundation granted $1.16 million to Australian firm Vaxxas Pty Ltd for its vaccine development and phase 2 MAP Industrial Proof of Principle work.

Alphabet Inc. (NASDAQ:GOOG) co-founder Sergey Brin has risen among the biggest philanthropists in the US in 2023. On May 15, Bloomberg reported that Brin gifted Alphabet Inc. (NASDAQ:GOOG) shares worth around $600 million to unnamed sources. In a filing, it was disclosed that 5.2 million Alphabet Inc. (NASDAQ:GOOG) shares were gifted by Brin. They could be directed to charity, or any other financial trusts, added Bloomberg. Brin has also been funding Parkinson’s research and has quietly donated $1.1 billion to date towards the research, as per Forbes.

25 Biggest Philanthropists in the US in 2023

Our Methodology

To compile our list of the biggest philanthropists in the US in 2023, we gathered data from Forbes. First, we took the top 50 wealthiest Americans and checked their philanthropy scores, which are measured on a scale of 1 to 5. The higher philanthropy score describes a larger percentage of wealth donations.

Here is the breakdown of the philanthropy scores:

A philanthropy score of 1 means 1% of wealth is given away.
A score of 2 means 1% to 4.99% of wealth is given away.
A score of 3 means 5% to 9.99% of wealth is given away.
A score of 4 means 10% to 19.99% of wealth is given away.
A score of 5 means more than 20% of the wealth is given away.

Therefore, individuals with higher philanthropy scores are ranked higher on the list. For similar philanthropy scores, we have considered net worth as a tie-breaker, and the individuals with higher net worth are ranked higher. We took the net worth data from the Forbes Real Time Billionaires database.

Our list is ranked in ascending order of philanthropy scores, primarily, and net worth, secondarily.

AI, Tariffs, Nuclear Power: One Undervalued Stock Connects ALL the Dots (Before It Explodes!)

Published on June 23, 2025 at by Inan Dogan, PhD

Artificial intelligence is the greatest investment opportunity of our lifetime. The time to invest in groundbreaking AI is now, and this stock is a steal!

AI is eating the world—and the machines behind it are ravenous.

Each ChatGPT query, each model update, each robotic breakthrough consumes massive amounts of energy. In fact, AI is already pushing global power grids to the brink.

Wall Street is pouring hundreds of billions into artificial intelligence—training smarter chatbots, automating industries, and building the digital future. But there’s one urgent question few are asking:

Where will all of that energy come from?

AI is the most electricity-hungry technology ever invented. Each data center powering large language models like ChatGPT consumes as much energy as a small city. And it’s about to get worse.

Even Sam Altman, the founder of OpenAI, issued a stark warning:

“The future of AI depends on an energy breakthrough.”

Elon Musk was even more blunt:

“AI will run out of electricity by next year.”

As the world chases faster, smarter machines, a hidden crisis is emerging behind the scenes. Power grids are strained. Electricity prices are rising. Utilities are scrambling to expand capacity.

And that’s where the real opportunity lies…

One little-known company—almost entirely overlooked by most AI investors—could be the ultimate backdoor play. It’s not a chipmaker. It’s not a cloud platform. But it might be the most important AI stock in the US owns critical energy infrastructure assets positioned to feed the coming AI energy spike.

As demand from AI data centers explodes, this company is gearing up to profit from the most valuable commodity in the digital age: electricity.

The “Toll Booth” Operator of the AI Energy Boom

It owns critical nuclear energy infrastructure assets, positioning it at the heart of America’s next-generation power strategy.
It’s one of the only global companies capable of executing large-scale, complex EPC (engineering, procurement, and construction) projects across oil, gas, renewable fuels, and industrial infrastructure.
It plays a pivotal role in U.S. LNG exportation—a sector about to explode under President Trump’s renewed “America First” energy doctrine.

Trump has made it clear: Europe and U.S. allies must buy American LNG.

And our company sits in the toll booth—collecting fees on every drop exported.

But that’s not all…

As Trump’s proposed tariffs push American manufacturers to bring their operations back home, this company will be first in line to rebuild, retrofit, and reengineer those facilities.

AI. Energy. Tariffs. Onshoring. This One Company Ties It All Together.

While the world is distracted by flashy AI tickers, a few smart investors are quietly scooping up shares of the one company powering it all from behind the scenes.

AI needs energy. Energy needs infrastructure.

And infrastructure needs a builder with experience, scale, and execution.

This company has its finger in every pie—and Wall Street is just starting to notice.

Wall Street is noticing this company also because it is quietly riding all of these tailwinds—without the sky-high valuation.

While most energy and utility firms are buried under mountains of debt and coughing up hefty interest payments just to appease bondholders…

This company is completely debt-free.

In fact, it’s sitting on a war chest of cash—equal to nearly one-third of its entire market cap.

It also owns a huge equity stake in another red-hot AI play, giving investors indirect exposure to multiple AI growth engines without paying a premium.

And here’s what the smart money has started whispering…

The Hedge Fund Secret That’s Starting to Leak Out

This stock is so off-the-radar, so absurdly undervalued, that some of the most secretive hedge fund managers in the world have begun pitching it at closed-door investment summits.

They’re sharing it quietly, away from the cameras, to rooms full of ultra-wealthy clients.

Why? Because excluding cash and investments, this company is trading at less than 7 times earnings.

And that’s for a business tied to:

The AI infrastructure supercycle
The onshoring boom driven by Trump-era tariffs
A surge in U.S. LNG exports
And a unique footprint in nuclear energy—the future of clean, reliable power

You simply won’t find another AI and energy stock this cheap… with this much upside.

This isn’t a hype stock. It’s not riding on hope.

It’s delivering real cash flows, owns critical infrastructure, and holds stakes in other major growth stories.

This is your chance to get in before the rockets take off!

Disruption is the New Name of the Game: Let’s face it, complacency breeds stagnation.

AI is the ultimate disruptor, and it’s shaking the foundations of traditional industries.

The companies that embrace AI will thrive, while the dinosaurs clinging to outdated methods will be left in the dust.

As an investor, you want to be on the side of the winners, and AI is the winning ticket.

The Talent Pool is Overflowing: The world’s brightest minds are flocking to AI.

From computer scientists to mathematicians, the next generation of innovators is pouring its energy into this field.

This influx of talent guarantees a constant stream of groundbreaking ideas and rapid advancements.

By investing in AI, you’re essentially backing the future.

The future is powered by artificial intelligence, and the time to invest is NOW.

Don’t be a spectator in this technological revolution.

Dive into the AI gold rush and watch your portfolio soar alongside the brightest minds of our generation.

A New Dawn is Coming to U.S. Stocks

Published on June 13, 2025 at by Insider Monkey Staff

I work for one of the largest independent financial publishers in the world – representing over 1 million people in 148 countries.

We’re independently funding today’s broadcast to address something on the mind of every investor in America right now…

Should I put my money in Artificial Intelligence?

Here to answer that for us… and give away his No. 1 free AI recommendation… is 50-year Wall Street titan, Marc Chaikin.

Marc’s been a trader, stockbroker, and analyst. He was the head of the options department at a major brokerage firm and is a sought-after expert for CNBC, Fox Business, Barron’s, and Yahoo! Finance…

But what Marc’s most known for is his award-winning stock-rating system. Which determines whether a stock could shoot sky-high in the next three to six months… or come crashing down.

That’s why Marc’s work appears in every Bloomberg and Reuters terminal on the planet…

And is still used by hundreds of banks, hedge funds, and brokerages to track the billions of dollars flowing in and out of stocks each day.

He’s used this system to survive nine bear markets… create three new indices for the Nasdaq… and even predict the brutal bear market of 2022, 90 days in advance.
