OpenAI yesterday closed its historic investment round, raising $6.6 billion at a $157 billion valuation.

• The ChatGPT maker also promised investors that it will convert into a for-profit entity — reflecting its transition from a research lab into a product-focused business — even pledging to return capital if the structural change isn't completed within two years.

Look ahead: The next step is for OpenAI to think about going public.

The big picture: The stunning reality is that $6.6 billion won't get OpenAI where it wants to go, as Axios' Scott Rosenberg explains.

• Sam Altman & Co. certainly could return to the private markets, given that the new round was oversubscribed, but there's much deeper liquidity in the public markets.
• Particularly given that OpenAI doesn't want investors that also back its top competitors.
• Plus, OpenAI now has a new CFO in Sarah Friar who previously led a listed company (NextDoor) and who effectively led another (Square/Block).

Zoom out: Going public is all about being able to tell a story, and this one almost writes itself.

• ChatGPT is almost becoming consumer shorthand for AI, and there is an argument that it could eventually become a multi-trillion dollar business (which is why VC backers in this round think they could get VC-level return multiples).
• It's a lottery ticket on a rocket ship, particularly for retail investors who missed out (or were too young) to bet on Amazon or Google in their early days.

The bottom line: OpenAI must eventually go public if it's to fulfill its promise. It will need the money, and its venture backers won't have other viable exit options.

• Doing it sooner rather than later, even if it requires an uncomfortable level of disclosure, is a show of strength that would lengthen its competitive advantage.

Bain Capital is supporting a share buyback plan by Korea Zinc, the world's largest refined zinc smelter, which is designed to prevent a takeover by MBK Partners.

Why it's the BFD: This is a bitter fight between the founding families of a $12 billion metals giant, each of which now has a deep-pocketed private equity firm on its side.

• On one side is the Chang family, which recently partnered with MBK to launch a $1.5 billion tender offer to buy a control stake in Korea Zinc. That tender ends tomorrow.
• On the other is the Choi family, which now plans to buy back $2 billion of Korea Zinc stock at an 11% premium to the Chang price. This is what Bain Capital is backing, via the purchase of another $322 million worth of shares.

Look ahead: The South Korean government would probably require that any future sale of Korea Zinc be to a domestic company, thus limiting exit opportunities for MBK.

The bottom line: "The battle and its aftermath will have implications far beyond Korea. Including affiliates, the company accounts for 12% of the world's zinc produced outside of China, 5% of its lead and around 9% of its silver. ... Those are vital for efforts to limit Beijing's metals dominance." — Bloomberg

DirecTV's proposed acquisition of Dish Networks is anything but a sure bet, as around 83% of Dish bondholders must accept a big haircut, Axios' Felix Salmon writes:

• "Bondholders aren't usually consulted in a merger. But this is a distressed deal in which the equity appears worthless — so the lenders scrambling to get paid back are actually the ones in control."
• And, as a reminder, TPG is on the hook to buy AT&T's 70% stake in DirecTV for $7.6 billion, even if the Dish deal fails.
