What happened
Intercontinental Exchange (ICE) disclosed in its 10-Q for the period ended 30 June 2026, filed 30 July 2026, that its combined Series D and Series E preferred holding in Polymarket was carried at about $2.0 billion as of 30 June. ICE reported that the stake represented about 22% of Polymarket's outstanding shares and about 14% on a fully diluted basis. The filing names the company as Blockratize, Inc., doing business as Polymarket, and gives no per-share price for either series.
The filing described how ICE built the position. On 7 October 2025 it agreed to buy 9.6 million Series D Preferred shares for $1.0 billion. On 26 March 2026 it invested an additional $600 million for about 4.2 million Series E shares. In the three months ended 31 March 2026 ICE recorded a $389 million gain by measuring the Series D stake at the implied fair value indicated by the Series E transaction price. It identified no downward adjustments or impairments in the three or six months ended 30 June 2026. Separately, in an April 2026 tender offer ICE bought about 0.4 million common shares for $40 million, under 1% of outstanding and fully diluted shares.
Key points
- ICE carried its Polymarket Series D and E preferred at about $2.0B as of 30 June 2026.1
- The stake was about 22% of outstanding shares and about 14% fully diluted.1
- ICE agreed to buy 9.6M Series D shares for $1.0B on 7 October 2025 and invested $600M for about 4.2M Series E shares on 26 March 2026.1
- A $389M gain was recorded in Q1 2026 by measuring Series D at the Series E price; no impairments were identified through 30 June.1
- In April 2026 ICE bought about 0.4M common shares for $40M in a tender offer.1
Why it matters
The $389 million gain came from measuring Series D at the implied fair value of the Series E transaction price, so the filed carrying value follows the latest round price.
ICE is a public company reporting its own holding and ownership shares. That gives an outside figure to compare with other accounts of who holds Polymarket stock.
The filing says Series D converts mandatorily on a qualified IPO or direct listing and states Series E rights are substantially similar. That ties the preferred holding to any future listing.
