I observed prayer along with the Messenger of Allah ﷺ and with Abu Bakr, Umar and Uthman (may Allah be pleased with all of them), but I never heard any one of them reciting Bismillah-ir-Rahman-ir-Rahim loudly. (Using translation from Muslim 399a)  

أحمد:١٢٨١٠ – حَدَّثَنَا مُحَمَّدُ بْنُ جَعْفَرٍ حَدَّثَنَا شُعْبَةُ وَحَجَّاجٌ قَالَ حَدَّثَنِي شُعْبَةُ قَالَ سَمِعْتُ قَتَادَةَ يُحَدِّثُ عَنْ أَنَسِ بْنِ مَالِكٍ قَالَ

صَلَّيْتُ مَعَ رَسُولِ اللهِ ﷺ وَأَبِي بَكْرٍ وَعُمَرَ وَعُثْمَانَ فَلَمْ أَسْمَعْ أَحَدًا مِنْهُمْ يَقْرَأُ {بِسْمِ اللهِ الرَّحْمَنِ الرَّحِيمِ} [الفاتحة 1] قَالَ حَجَّاجٌ قَالَ شُعْبَةُ قَالَ قَتَادَةُ سَأَلْتُ أَنَسَ بْنَ مَالِكٍ بِأَيِّ شَيْءٍ كَانَ رَسُولُ اللهِ ﷺ يَسْتَفْتِحُ الْقِرَاءَةَ؟ فَقَالَ إِنَّكَ لَتَسْأَلُنِي عَنْ شَيْءٍ مَا سَأَلَنِي عَنْهُ أَحَدٌ

ahmad:12974 – Ismāʿīl > Saʿīd b. Yazīd

[Machine] Narrated Anas bin Malik: I asked the Prophet ﷺ if he used to begin reciting the Quran with "Bismillah ar-Rahman ar-Rahim" (In the name of Allah, the Most Gracious, the Most Merciful) or with "Alhamdulillahi Rabbil 'Alameen" (Praise be to Allah, the Lord of all the worlds)? He replied, "You asked me about something no one has asked me before."

قَتَادَةُ سَأَلْتُ أَنَسَ بْنَ مَالِكٍ بِأَيِّ شَيْءٍ كَانَ يَسْتَفْتِحُ رَسُولُ اللهِ ﷺ الْقِرَاءَةَ؟ قَالَ إِنَّكَ لَتَسْأَلُنِي عَنْ شَيْءٍ مَا سَأَلَنِي عَنْهُ أَحَدٌ

Shu'bah said: I asked Qatadah, 'Did you hear this from Anas?' He replied, 'Yes, we asked him about it.'"

صَلَّيْتُ خَلْفَ رَسُولِ اللهِ ﷺ وَخَلْفَ أَبِي بَكْرٍ وَعُمَرَ وَعُثْمَانَ فَلَمْ يَكُونُوا يَسْتَفْتِحُونَ الْقِرَاءَةَ بِ {بِسْمِ اللهِ الرَّحْمَنِ الرَّحِيمِ} [الفاتحة 1] قَالَ شُعْبَةُ فَقُلْتُ لِقَتَادَةَ أَسَمِعْتَهُ مِنْ أَنَسٍ؟ قَالَ نَعَمْ نَحْنُ سَأَلْنَاهُ عَنْهُ
