Here's your Forbes Daily Briefing for Friday, December 5th.

Today on Forbes, Eric Trump has gotten 10 times richer since Dad's election.

Eric Trump, who has been managing his father's business for nine years now, does not own a stake in any of the real estate for which the Trump organization is known.

He did, however, inherit something even more valuable. Over the last year, Donald Trump has

offered a masterclass in turning political fame into personal fortune. Eric has proven to be the best

student and is now worth an estimated $400 million, more than any of his

siblings. The biggest single chunk of his fortune is a stake in American Bitcoin, a company that

mines and holds cryptocurrency. At the end of September, it had 3,418 Bitcoin on hand, worth

about $320 million at today's prices. The market cap of American

Bitcoin now sits at over $2 billion, valuing Eric's 7.3% stake at about $160 million.

In early September, Eric boasted on television, quote, we have massive aspirations to be the absolute best crypto company on Earth.

I think you know how hard we all charge.

We're pretty known for that, and we're having a lot of fun doing this.

It's difficult not to have fun when you're making millions of dollars,

and American Bitcoin is hardly the only valuable venture on

Eric's mind. His share of World Liberty Financial, which his father launched alongside his son's

Eric, Donald Trump Jr., and Baron, shortly before the election last year, has netted Eric

an estimated $135 million. Combined with a few other new assets, the two crypto ventures have

boosted Eric's net worth to 10 times where it sat on the eve of his father's return to the

White House. Reached for comment, Eric disputed the valuation, but declined to explain why.

Eric's American Bitcoin windfall began as American data centers, or ADC, an opaque venture that

he launched with his older brother in February.
