Forbes Daily Briefing

Last year, the GOP’s legacy donor class and its newer crop of tech and finance billionaires found common cause: writing enormous checks to support Donald Trump. 

In February, billionaire Kelcy Warren and his fossil fuel pipeline company, Energy Transfer, each sent $12.5 million to MAGA Inc., a Trump-aligned super PAC. Just a few months later, OpenAI cofounder and president Greg Brockman and his wife cut checks for $12.5 million each. 

That makes Warren and Brockman the biggest individual donors to MAGA Inc. But the roster is deeper than two names and four eight-figure checks. Forbes counts at least 24 billionaires or billionaire families who have given over $1 million, according to Federal Election Commission filings covering through the end of March. (Brockman is not currently on Forbes’ list of billionaires, but he did claim to be one in testimony related to Elon Musk’s lawsuit against OpenAI). Collectively, these ten-figure club members, plus Brockman, donated $118 million, about a third of the $350 million war chest MAGA Inc has built.

Last week, Strategy overtook BlackRock, issuer of the world’s largest bitcoin exchange-traded fund, IBIT, to become the world’s largest institutional holder of bitcoin. The milestone followed yet another enormous purchase: between April 13 and April 19, according to a recent Securities and Exchange Commission filing, Strategy bought $2.54 billion worth of bitcoin, its largest acquisition since November 2024. The purchase brought the company’s total holdings to 815,061 BTC—about 3.88% of bitcoin’s fixed 21 million supply—currently worth around $65 billion. The only larger holder is thought to be Satoshi Nakamoto, the elusive founder of the cryptocurrency who disappeared 15 years ago.

The funding for Strategy’s latest bitcoin buying spree is not coming from flooding the market with common shares or convertible debt, but mainly from what traders affectionately call “Stretch,” a high-yield perpetual preferred stock the company has been issuing under the symbol STRC. Saylor, Strategy’s chairman, has been touting Stretch as the critical underpinning of the next phase of his bitcoin empire.

From 2020 through 2024, Strategy financed its bitcoin binge largely by selling convertible notes and issuing common stock. It was a shrewd display of financial engineering while it lasted. As bitcoin climbed and investors bid Strategy shares to eye-popping premiums over the value of the company’s underlying bitcoin, Saylor could keep issuing more bonds convertible into stock and selling common shares to hedge funds and other investors anticipating a windfall. At points, the stock traded at two to three times the value of bitcoin on its balance sheet.

The AI boom created a colossal market for compute—GPUs, networking gear and the massive datacenters that run it all. It also bolstered a second less celebrated market: protecting those facilities and the crown-jewel chips inside from threats.

On top of rising anti-data center sentiment stateside, the war in Iran has turned that problem into a line item. “Data centers are secondary targets right after obvious military sites,” says Matt McCrann, former executive at drone defense company DroneShield, who has worked with data centers in the U.S. and Middle East.

That shift matters because the AI data centers being built these days aren’t just expensive—they’re also possible strategic infrastructure during times of war. Enemies don’t need to hit a military site to degrade an opponent’s capability; they can hit compute that potentially underpins communications, logistics, payments and even military planning.

Mariana Minerals CEO and cofounder Turner Caldwell is betting that the next big use for AI won’t be another chatbot—it’ll be a copper mine.

His startup, Mariana Minerals, is launching the world’s first autonomous mining operation today at its Copper One mine in remote southeast Utah: automated drills do the digging, giant robotic haul trucks move ore for processing, and an AI-enabled platform called MarianaOS will track and direct the entire operation. The company is even using Boston Dynamics’ Spot robot dog, packed with sensors, to patrol the 10,000-acre site and inspect conditions.

If it works, Mariana could help boost both U.S. copper supply and U.S. copper refining as demand for the metal climbs and the politics around “critical minerals” grows louder. In a few years, the company could be generating hundreds of millions of dollars in revenue from both the Utah copper mine and a separate lithium refining operation it’s setting up in Texas, recovering the mineral from wastewater from oil and gas fields.
