Sibiryakov graduated from the Zurich polytechnic institute in Switzerland. Later in life, he financed the polar expeditions of Adolf Erik Nordenskiöld (see Vega Expedition) and A.V. Grigoriev. He also sponsored the publication of works on Siberia's history. In 1880, he made an attempt to enter the Yenisei estuary through the Kara Sea on a schooner. In 1884, Sibiryakov reached the Pechora estuary on the "Nordenskjöld" steamer and proceeded up the river. He then crossed the Urals using reindeers and reached Tobolsk by the Tobol River. Sibiryakov contributed significantly^[how?] to Siberia's economic development.

After the Russian revolution in 1917, Sibiryakov left Russia and spent the rest of his life in exile. He died in Nice, France, in poverty, aged 84. His funeral was paid for by Swedish government, as a sign of gratitude for Sibiryakov's friendly relations with Sweden. The news reports at the time stated that only the consul of Sweden and two other members of the Swedish diplomatic mission in France attended Sibiryakov's funeral.^[1]

Sibiryakov Island, an island in the Kara Sea at the mouth of the Yenisei River, is named after him, as well as icebreakers A. Sibiryakov and Sibiryakov.
