On June 15, 2026, BIG3 HoldCo LLC, which is a party to the previously disclosed Business Combination Agreement (the “Business Combination Agreement”), dated as of June 15, 2026, with Graf Global Corp. and Halfcourt Holdco, Inc., among other parties, through its social media accounts, shared the following post on its Instagram (@thebig3) account:
On June 15, 2026, Sports Business Journal published the following article regarding the previously disclosed Business Combination Agreement:
Big3 looks to feed off NBA Finals frenzy as ninth season begins
Ice Cube noted Big3 remains in the market with a secondary media deal.
With the NBA Finals over, Ice Cube is hoping the Big3 can “feed off the frenzy” from Knicks-Spurs as the 3-on-3 hoops league begins its ninth season this weekend.
“We always saw this as a complementary league, especially for fans,” Cube told SBJ. “When the [NBA] season is done and the Finals are over, fans have a hangover. They want more. And here we are with a real season. ... We don’t have 82 — we have eight games. … We look at what the NFL does. Every game counts.”
Cube said the Big3 is “very fortunate” to have CBS as a main partner (that deal is in its seventh year). “They provide us with the best in the business when it comes to production,” he said. “We get the same guys that produce the Super Bowl. So it’s pretty impressive for a league like ours to have a slot like that with CBS.”
A package of games remains out in market for Big3, and Cube noted the league has been in talks with a number of platforms. That smaller package of non-CBS games was with Vice TV last year, and it streamed on X in 2024. “We’re looking for people to take the non-CBS games, and hopefully it’ll be a network … or a platform that can help grow the game,” Cube said.
The Big3 also has a new element in midweek re-airs this season, as BET just struck a deal to show CBS Big3 games from the weekend on a Monday night. It’s the first time Big3 has midweek re-airs since Season 2.
‘Best kept secret’
Cube continues to feel that the NBA has hindered Big3’s growth and traditional media prospects, having alleged in the past that the NBA has encouraged sponsors and networks to avoid his young league. That makes social media even more important for Big3, which aims to go public via SPAC in Q4.
“Social media is how we can combat that,” he said. “We control that. We control the scenario. We were the first to let influencers actually air the games and comment and bring in their audience and expand their audience. … Between 2024 and 2025, [social media growth for the Big3 has] been up 7,000%. So we’ve been doing great.”
