AI Reasoning: I searched Marathon Petroleum’s public filings, press releases and news (company site, SEC annual report and press releases). The most relevant investment-related activities found relate to corporate operations and community projects reported in 2024 and early 2025, but there is no evidence of Marathon Petroleum making an equity investment in a startup within the last 12 months. The last identifiable investment-like activity tied to outside projects was in 2024 (startup or project referenced in the 2024 Sustainability Report). That places the most recent known investment more than 12 months ago, so the appropriate classification is not-active. The startup mentioned in the sustainability report was an external project providing a cellular tower (referenced as a partner project).

Not Active – No known investments in the last 12 months.

Low Activity – Only known investments between the last 12 and 6 months.

Active – Known investments between the last 6 and 3 months.

Very Active – Known investments in the last 3 months.
