This is a transparent, rules-based screen — not a prediction or a probability. Additions to the S&P 500 are decided by the S&P Index Committee at its sole discretion; meeting every published criterion is necessary but never sufficient, and the committee can add a company that screens poorly or pass over one that screens well.

What this screen checks

Every company listed above passes each of these eligibility rules. Meeting them is necessary — never sufficient.

  • U.S.-domiciled operating company (incl. foreign-incorporated 10-K filers S&P treats as U.S.)
  • Common stock, equity REIT, or BDC — no ETFs, ADRs, MLPs, or SPACs
  • Market cap at or above the published threshold (≈$22.7B, as of 2025-07-01)
  • Public float of more than 50% of shares outstanding
  • Positive GAAP earnings — most recent quarter and trailing four quarters combined
  • At least 12 months since its IPO (screen heuristic)
  • ≥250k shares traded in each of the prior 6 months

Public float is enforced here: a company whose public float is below 50% of shares outstanding is excluded, even if it clears every other rule. Where free float is not yet available it shows as “Float unverified” and the company is listed but not confirmed against this rule. The float-adjusted liquidity ratio remains part of the official rules but is not yet evaluated here.

Additions usually follow removals: when a current member is acquired or removed, a new company takes its place. Watch pending mergers and acquisitions among current members — they create the openings these candidates compete for.
