Theodore Rachmat's net worth is $4.45 billion, per Forbes' "Indonesia's 50 Richest 2025" list, published 10 December 2025, ranking him 15th richest in Indonesia in the "Diversified" category. Rachmat, known in Indonesia as Teddy, spent two decades rising to CEO of Astra International, the conglomerate his uncle William Soeryadjaya founded, before leaving in 1998 to build Triputra Group on his own. He is also Vice President Commissioner of Alamtri Resources Indonesia, the coal miner formerly known as Adaro Energy.
| Publisher | Timing | Figure | Note |

| Forbes, "Indonesia's 50 Richest 2025" | 10 December 2025 | $4.45 billion | #15 in Indonesia, "Diversified" |
Forbes' annual list is the only figure this article treats as fact, because it carries a clear date and a named methodology. Forbes also runs a separate real-time profile page for Rachmat that places him at #954 on Forbes' 2026 World's Billionaires list, but this run's research could not attach a dated, standalone dollar figure to that rank from Forbes itself, so it is stated here only as a rank, not a number. Bloomberg Markets maintains its own profile page for Rachmat, confirming it tracks him, but no dated Bloomberg Billionaires Index figure for him individually was found. As with Dewi Kam, when a second publisher's number cannot be pinned down, that gap is worth stating plainly rather than papered over with an estimate.
Rachmat joined Astra International in 1968, the auto and conglomerate group his uncle William Soeryadjaya founded, and eventually became its CEO. He left in 1998 to found Triputra Group, which now spans agriculture, manufacturing, mining, trading and motor dealerships. Its most visible listed unit is PT Triputra Agro Persada Tbk (TAPG), a palm oil producer that IPO'd on the Indonesia Stock Exchange in April 2021.
Separately, Rachmat sits as Vice President Commissioner of PT Alamtri Resources Indonesia Tbk (ADRO), linkable on NetWort, the coal exporter renamed from Adaro Energy in November 2024. Per an undated MarketScreener shareholder snapshot, he personally holds 812,988,601 shares, about 2.766% of the company. At Alamtri's IDX closing price of Rp2,540 on 7 August 2026 (stockanalysis.com), that stake is worth roughly Rp2.06 trillion, about $117 million at the Rp17,631-per-dollar rate Pluang quoted on 8 September 2026, a straightforward multiplication of two dated figures rather than an estimate. That is only around 2.6% of his $4.45 billion Forbes total, so most of his tracked wealth sits in privately held Triputra Group, not in the one disclosed public stake.
Alamtri Resources' own results improved through 2026. Net income reached $128.1 million in the first quarter, up 67.1% year over year from $76.7 million a year earlier, its strongest quarterly earnings since the post-rename repositioning, per NH Korindo Sekuritas Indonesia's Q1 2026 research update. UOB Kay Hian separately forecasts full-year 2026 net profit rising 60% to $719 million, citing higher metallurgical coal prices, higher sales volume and a growing aluminium smelter contribution, a forecast, not a reported result. No publisher in this run's research has connected either figure to an updated personal net worth number for Rachmat himself, and this article does not draw that line either. Triputra Agro Persada's own results were not separately sourced this run.
Harder to verify than a single-stock fortune. Triputra Group, the larger share of Rachmat's wealth by Forbes' own $4.45 billion figure, is privately held and does not disclose the way a listed company must. His one confirmed public stake, in Alamtri Resources, is both small relative to the total and dated to an undated secondary snapshot rather than a same-day filing. Forbes' own real-time tracker places him on its 2026 global list without a figure this run could confirm, and Bloomberg tracks him without a public number found. That combination, a mostly private core plus unconfirmed secondary trackers, is closer to the multi-entity spread already documented for Hermanto Tanoko than to a fortune anchored on one clean, daily-priced stock.
Rachmat's path, from rising through a conglomerate someone else founded to building his own, echoes how Boy Thohir holds a personal stake in the same company, Alamtri Resources, while running businesses well beyond it. It also lines up with Franky Widjaja's Sinar Mas fortune in one respect: both sit mostly in private group structures that a single Forbes number cannot fully unpack for an outside reader. NetWort's asset screener can track the one public piece of a story like this, Alamtri Resources' share price, even when the larger private group behind it stays opaque.
