The Globe and Mail reports in its Friday edition that SpaceX shares begin trading today, after the company announced Thursday that it completed the sale of 555.6 million shares at $135 (U.S.) each, raising a record $75-billion (U.S.). The Globe's Sophia Bertuzzi writes that in anticipation of the initial public offering, and with Anthropic and OpenAI expected to be following suit, Nasdaq, S&P Dow Jones Indices and other index providers consulted with Wall Street bankers earlier this year regarding proposed changes to their index methodology. Newly listed public companies typically aren't eligible for inclusion in an index until after what's known as a "seasoning period." For the Nasdaq 100, that is typically three months, while the S&P 500 maintains a one-year delay. Even after that period -- which exists to allow the stock price to stabilize after its IPO -- companies must meet other requirements in order to be considered. Peter Haynes, managing director at TD Securities, said the S&P's decision to maintain its index eligibility criteria runs contrary to what the industry expected. "If we start making judgment calls on what belongs [in the index] and what doesn't, then we are making active bets," he said.
