The story so far

Polymarket has closed a new funding round that investors say values the prediction‑market platform at roughly $21 billion. What’s striking is the split reporting on the amount raised: some outlets cite a $300 million infusion, while others describe a $1 billion total round.

The Wall Street Journal reports that 1789 Capital contributed about $300 million, a figure echoed in its exclusive story linking Donald Trump Jr.’s fund to that same contribution. Dealroom and Bloomberg describe a $1 billion round led by 1789 Capital that sets the $21 billion valuation.

The New York Times similarly notes Donald Trump Jr.’s firm as the lead investor in a $1 billion financing. Because the figures differ, the precise size of the Trump‑linked contribution versus the broader round remains unclear.
