Mark Zuckerberg’s push for a new Meta share class began well before the company’s latest earnings release. Since July, he had been negotiating with the board over the prospect of California’s Proposition 40, a proposed one-time 5% levy on billionaires who were California residents as of Jan. 1, 2026.¹

The pressure peaked at a Sept. 9 dinner with directors. Zuckerberg said he would list his Palo Alto home if no agreement emerged, giving the board 96 hours before a planned Sept. 13 listing—a move that would have publicly underscored the possibility of his leaving the state.¹ The filings put his potential tax bill at nearly $12.5 billion, based on an estimated $247 billion fortune. Selling existing supervoting Meta stock to cover it, the company said, could cut his voting power from 60.6% to 53%.¹

On Wednesday, Meta unveiled the compromise: a new non-voting Class C share, to be issued to shareholders in January. The stock would give Zuckerberg an asset he could sell without surrendering voting control, while also giving Meta another financing tool for acquisitions, employee pay and its costly AI expansion.²

Meta’s public rationale is broader than one founder’s tax planning. The company said the investment needed to compete through the industry’s AI transformation is “significant,” and CFO Susan Li said the shares would provide “flexibility to invest behind the unprecedented momentum” driven by AI.² Meta expects annual capital expenditure of $135 billion to $145 billion, after reporting $34.91 billion in third-quarter spending.²

The governance argument is equally explicit. A board special committee concluded Zuckerberg remained the best leader for Meta’s future, and the company said Class C stock would preserve the “founder-led model” behind its success.³ For investors, the move functions like a two-for-one split; for Zuckerberg, it is a durable hedge against both dilution and California’s tax threat.³
