Lewis Hamilton fell ill following the Singapore Grand Prix, and race organisers released him from his post-race media obligations as a result. Hamilton was transported to the circuit's medical facility at Marina Bay for evaluation.

After exiting his Ferrari in parc ferme, Hamilton was observed crouching with his gaze directed downward before receiving medical attention. A broadcaster on air relayed that Hamilton had stepped away from his car feeling unwell and had been taken to the medical centre, though the team had anticipated speaking with him before the programme concluded. Hamilton did not address reporters — from either television or print — in the post-race media area.

Starting from third on the grid, Hamilton dropped to sixth by the finish, with the decision to skip a second tyre change costing him those positions. A planned two-stop tyre strategy for Hamilton was set aside once data showed wear rates running lower than pre-race forecasts had indicated.

An opportunity for a tyre change at reduced cost became available when the virtual safety car was deployed during the latter stages of the race. Both Ferrari drivers were called to the pits. Charles Leclerc brought his car in from second place on the road, while Hamilton opted against following the same strategy.

Tyre wear caught up with Hamilton after he chose to stay out, and his position gradually fell until he finished sixth. On the radio during his return to the pit lane, he told the team the strategy outcome that day had been his fault. Hamilton also put forward a pledge to perform at a higher level in the next race.

After completing 62 laps through the streets of Singapore, Hamilton crouched down in parc ferme, visibly affected by the race's heat and humidity.

Ferrari team principal Frédéric Vasseur offered no update on Hamilton's physical condition but stated that the decision to stay out during the virtual safety car period had come from the driver himself, and that the team's plan had been to bring both cars in for fresh tyres at the same time. Vasseur said that calling both drivers to the pits at that point would have secured second and third place, given the positions the team held on track.

Race data confirmed that missing the pit entry cost Hamilton a place on the podium. Vasseur noted that the team had been unable to prevent Max Verstappen from taking the victory, describing Hamilton's weekend display as acceptable while pointing to the races ahead as the priority. Vasseur also acknowledged that Verstappen had held a pace advantage throughout the weekend, while noting that both drivers and the team as a whole had put in a solid showing across those same days.
